See issue - [#6223](https://github.com/nim-lang/Nim/issues/6223) for more details. - You can use ``substr(str, start, finish)`` to get the old behaviour back, - see [this commit](https://github.com/nim-lang/nimbot/commit/98cc031a27ea89947daa7f0bb536bcf86462941f) for an example. - -- ``strutils.split`` and ``strutils.rsplit`` with an empty string and a - separator now returns that empty string. - See issue [#4377](https://github.com/nim-lang/Nim/issues/4377). - -- Arrays of char cannot be converted to ``cstring`` anymore, pointers to - arrays of char can! This means ``$`` for arrays can finally exist - in ``system.nim`` and do the right thing. This means ``$myArrayOfChar`` changed - its behaviour! Compile with ``-d:nimNoArrayToString`` to see where to fix your - code. - -- `reExtended` is no longer default for the `re` constructor in the `re` - module. - -- The behavior of ``$`` has been changed for all standard library collections. The - collection-to-string implementations now perform proper quoting and escaping of - strings and chars. - -- `newAsyncSocket` taking an `AsyncFD` now runs `setBlocking(false)` on the - fd. - -- ``mod`` and bitwise ``and`` do not produce ``range`` subtypes anymore. This - turned out to be more harmful than helpful and the language is simpler - without this special typing rule. - -- ``formatFloat``/``formatBiggestFloat`` now support formatting floats with zero - precision digits. The previous ``precision = 0`` behavior (default formatting) - is now available via ``precision = -1``. - -- Moved from stdlib into Nimble packages: - - [``basic2d``](https://github.com/nim-lang/basic2d) - _deprecated: use ``glm``, ``arraymancer``, ``neo``, or another package instead_ - - [``basic3d``](https://github.com/nim-lang/basic3d) - _deprecated: use ``glm``, ``arraymancer``, ``neo``, or another package instead_ - - [``gentabs``](https://github.com/lcrees/gentabs) - - [``libuv``](https://github.com/lcrees/libuv) - - [``numeric``](https://github.com/lcrees/polynumeric) - - [``poly``](https://github.com/lcrees/polynumeric) - - [``pdcurses``](https://github.com/lcrees/pdcurses) - - [``romans``](https://github.com/lcrees/romans) - - [``libsvm``](https://github.com/nim-lang/libsvm_legacy) - - [``joyent_http_parser``](https://github.com/nim-lang/joyent_http_parser) - -- Proc [toCountTable](https://nim-lang.org/docs/tables.html#toCountTable,openArray[A]) - now produces a `CountTable` with values correspoding to the number of occurrences - of the key in the input. It used to produce a table with all values set to `1`. - - Counting occurrences in a sequence used to be: - - ```nim - let mySeq = @[1, 2, 1, 3, 1, 4] - var myCounter = initCountTable[int]() - - for item in mySeq: - myCounter.inc item - ``` - - Now, you can simply do: - - ```nim - let - mySeq = @[1, 2, 1, 3, 1, 4] - myCounter = mySeq.toCountTable() - ``` - -- If you use ``--dynlibOverride:ssl`` with OpenSSL 1.0.x, you now have to - define ``openssl10`` symbol (``-d:openssl10``). By default OpenSSL 1.1.x is - assumed. - -- ``newNativeSocket`` is now named ``createNativeSocket``. - -- ``newAsyncNativeSocket`` is now named ``createAsyncNativeSocket`` - and it no longer raises an OS error but returns an ``osInvalidSocket`` when - creation fails. - -- The ``securehash`` module is now deprecated. Instead import ``std / sha1``. - -- The ``readPasswordFromStdin`` proc has been moved from the ``rdstdin`` - to the ``terminal`` module, thus it does not depend on linenoise anymore. - #### Breaking changes in the compiler -- ``\n`` is now only the single line feed character like in most - other programming languages. The new platform specific newline escape sequence is - written as ``\p``. This change only affects the Windows platform. - -- The overloading rules changed slightly so that constrained generics are - preferred over unconstrained generics. (Bug #6526) - -- We changed how array accesses "from backwards" like ``a[^1]`` or ``a[0..^1]`` are - implemented. These are now implemented purely in ``system.nim`` without compiler - support. There is a new "heterogenous" slice type ``system.HSlice`` that takes 2 - generic parameters which can be ``BackwardsIndex`` indices. ``BackwardsIndex`` is - produced by ``system.^``. - This means if you overload ``[]`` or ``[]=`` you need to ensure they also work - with ``system.BackwardsIndex`` (if applicable for the accessors). - -- The parsing rules of ``if`` expressions were changed so that multiple - statements are allowed in the branches. We found few code examples that - now fail because of this change, but here is one: - -```nim -t[ti] = if exp_negative: '-' else: '+'; inc(ti) -``` - -This now needs to be written as: - -```nim -t[ti] = (if exp_negative: '-' else: '+'); inc(ti) -``` - -- The experimental overloading of the dot ``.`` operators now take - an ``untyped``` parameter as the field name, it used to be - a ``static[string]``. You can use ``when defined(nimNewDot)`` to make - your code work with both old and new Nim versions. - See [special-operators](https://nim-lang.org/docs/manual.html#special-operators) - for more information. - -- ``yield`` (or ``await`` which is mapped to ``yield``) never worked reliably - in an array, seq or object constructor and is now prevented at compile-time. - ### Library additions -- **Added ``sequtils.mapLiterals`` for easier construction of array and tuple literals.** - -- Added ``system.runnableExamples`` to make examples in Nim's documentation easier - to write and test. The examples are tested as the last step of - ``nim doc``. - -- Implemented ``getIoHandler`` proc in the ``asyncdispatch`` module that allows - you to retrieve the underlying IO Completion Port or ``Selector[AsyncData]`` - object in the specified dispatcher. - -- For string formatting / interpolation a new module - called [strformat](https://nim-lang.org/docs/strformat.html) has been added - to the stdlib. - -- The `ReadyKey` type in the selectors module now contains an ``errorCode`` - field to help distinguish between ``Event.Error`` events. - -- Implemented an `accept` proc that works on a `SocketHandle` in - ``nativesockets``. - -- Added ``algorithm.rotateLeft``. - -- Added ``typetraits.$`` as an alias for ``typetraits.name``. - -- Added ``system.getStackTraceEntries`` that allows you to access the stack - trace in a structured manner without string parsing. - -- Added ``parseutils.parseSaturatedNatural``. - -- Added ``macros.unpackVarargs``. - -- Added support for asynchronous programming for the JavaScript backend using - the `asyncjs` module. - -- Added true color support for some terminals. Example: -```nim -import colors, terminal - -const Nim = "Efficient and expressive programming." - -var - fg = colYellow - bg = colBlue - int = 1.0 - -enableTrueColors() - -for i in 1..15: - styledEcho bgColor, bg, fgColor, fg, Nim, resetStyle - int -= 0.01 - fg = intensity(fg, int) - -setForegroundColor colRed -setBackgroundColor colGreen -styledEcho "Red on Green.", resetStyle -``` - ### Library changes -- ``echo`` now works with strings that contain ``\0`` (the binary zero is not - shown) and ``nil`` strings are equal to empty strings. - -- JSON: Deprecated `getBVal`, `getFNum`, and `getNum` in favour of - `getBool`, `getFloat`, `getBiggestInt`. A new `getInt` procedure was also - added. - -- ``rationals.toRational`` now uses an algorithm based on continued fractions. - This means its results are more precise and it can't run into an infinite loop - anymore. - -- ``os.getEnv`` now takes an optional ``default`` parameter that tells ``getEnv`` - what to return if the environment variable does not exist. - -- The ``random`` procs in ``random.nim`` have all been deprecated. Instead use - the new ``rand`` procs. The module now exports the state of the random - number generator as type ``Rand`` so multiple threads can easily use their - own random number generators that do not require locking. For more information - about this rename see issue [#6934](https://github.com/nim-lang/Nim/issues/6934) - -- ``writeStackTrace`` is now proclaimed to have no IO effect (even though it does) - so that it is more useful for debugging purposes. - -- ``db_mysql`` module: ``DbConn`` is now a ``distinct`` type that doesn't expose the - details of the underlying ``PMySQL`` type. - -- ``parseopt2`` is now deprecated, use ``parseopt`` instead. - ### Language additions -- It is now possible to forward declare object types so that mutually - recursive types can be created across module boundaries. See - [package level objects](https://nim-lang.org/docs/manual.html#package-level-objects) - for more information. - -- Added support for casting between integers of same bitsize in VM (compile time and nimscript). - This allows to, among other things, reinterpret signed integers as unsigned. - -- Custom pragmas are now supported using pragma ``pragma``, please see language - manual for details. - -- Standard library modules can now also be imported via the ``std`` pseudo-directory. - This is useful in order to distinguish between standard library and nimble package - imports: - - ```nim - import std / [strutils, os, osproc] - import someNimblePackage / [strutils, os] - ``` - ### Language changes -- The **unary** ``<`` is now deprecated, for ``.. <`` use ``..<`` for other usages - use the ``pred`` proc. - -- Bodies of ``for`` loops now get their own scope: - -```nim -# now compiles: -for i in 0..4: - let i = i + 1 - echo i -``` - -- To make Nim even more robust the system iterators ``..`` and ``countup`` - now only accept a single generic type ``T``. This means the following code - doesn't die with an "out of range" error anymore: - -```nim -var b = 5.Natural -var a = -5 -for i in a..b: - echo i -``` - -- ``atomic`` and ``generic`` are no longer keywords in Nim. ``generic`` used to be - an alias for ``concept``, ``atomic`` was not used for anything. - -- The memory manager now uses a variant of the TLSF algorithm that has much - better memory fragmentation behaviour. According - to [http://www.gii.upv.es/tlsf/](http://www.gii.upv.es/tlsf/) the maximum - fragmentation measured is lower than 25%. As a nice bonus ``alloc`` and - ``dealloc`` became O(1) operations. - -- The compiler is now more consistent in its treatment of ambiguous symbols: - Types that shadow procs and vice versa are marked as ambiguous (bug #6693). - -- codegenDecl pragma now works for the JavaScript backend. It returns an empty - string for function return type placeholders. - -- Extra semantic checks for procs with noreturn pragma: return type is not allowed, - statements after call to noreturn procs are no longer allowed. - -- Noreturn proc calls and raising exceptions branches are now skipped during common type - deduction in ``if`` and ``case`` expressions. The following code snippets now compile: - ```nim - import strutils - let str = "Y" - let a = case str: - of "Y": true - of "N": false - else: raise newException(ValueError, "Invalid boolean") - let b = case str: - of nil, "": raise newException(ValueError, "Invalid boolean") - elif str.startsWith("Y"): true - elif str.startsWith("N"): false - else: false - let c = if str == "Y": true - elif str == "N": false - else: - echo "invalid bool" - quit("this is the end") - ``` - -- Pragmas now support call syntax, for example: ``{.exportc"myname".}`` and - ``{.exportc("myname").}`` - -- The ``deprecated`` pragma now supports a user-definable warning message for procs. - - ```nim - proc bar {.deprecated: "use foo instead".} = - return - - bar() - ``` - ### Tool changes -- The ``nim doc`` command is now an alias for ``nim doc2``, the second version of - the documentation generator. The old version 1 can still be accessed - via the new ``nim doc0`` command. - -- Nim's ``rst2html`` command now supports the testing of code snippets via an RST - extension that we called ``:test:``:: - - ```rst - .. code-block:: nim - :test: - # shows how the 'if' statement works - if true: echo "yes" - ``` - ### Compiler changes ### Bugfixes - -- Fixed "ReraiseError when using try/except within finally block" -

Behavior should be identical to the old behavior if empty partial symbol tables are passed. "Partialness" of the symbol table refers to the fact that one need only specify option keys that are toggles/booleans/do not take arguments, hence the "NoArg" suffixes in shortNoArg and longNoArg. commandLineParams() returns seq[TaintedString], so use that consistently in getopt() and initOptParser(seq[TaintedString]) dropping the taint at the quoting stage just as with the paramStr() logic. Fix capitalization inconsistency of cmdLongOption. Export OptParser.cmd and OptParser.pos so that, at least *in principle*, users of this API can handle "--" option processing termination or some "git-like" sub-command stop word with a separate option sub-syntax. { Eg., ``case p.key of "": echo "trailing non-option args: ", p.cmd[p.pos..^1]`` or ``case p.kind of cmdArgument: if p.key == "mysubcmd": ...``. } Really, searching for the last delimiter before p.pos is probably needed to frame the trailing text..Not the nicest API, but still possible with effort. * Make requested changes from string to seq[char] (see https://github.com/nim-lang/Nim/pull/7297) * Document new behavior and elaborate on some special cases. * NoArg => NoVal to be less ambiguous/more clear. * Add more documentation and an example snippet. * Tweak language.

Several of Nim's features may need more +precise wording. This manual is constantly evolving until the 1.0 release and is +not to be considered as the final proper specification. + +This document describes the lexis, the syntax, and the semantics of Nim. + +The language constructs are explained using an extended BNF, in which ``(a)*`` +means 0 or more ``a``'s, ``a+`` means 1 or more ``a``'s, and ``(a)?`` means an +optional *a*. Parentheses may be used to group elements. + +``&`` is the lookahead operator; ``&a`` means that an ``a`` is expected but +not consumed. It will be consumed in the following rule. + +The ``|``, ``/`` symbols are used to mark alternatives and have the lowest +precedence. ``/`` is the ordered choice that requires the parser to try the +alternatives in the given order. ``/`` is often used to ensure the grammar +is not ambiguous. + +Non-terminals start with a lowercase letter, abstract terminal symbols are in +UPPERCASE. Verbatim terminal symbols (including keywords) are quoted +with ``'``. An example:: + + ifStmt = 'if' expr ':' stmts ('elif' expr ':' stmts)* ('else' stmts)? + +The binary ``^*`` operator is used as a shorthand for 0 or more occurrences +separated by its second argument; likewise ``^+`` means 1 or more +occurrences: ``a ^+ b`` is short for ``a (b a)*`` +and ``a ^* b`` is short for ``(a (b a)*)?``. Example:: + + arrayConstructor = '[' expr ^* ',' ']' + +Other parts of Nim - like scoping rules or runtime semantics are only +described in the, more easily comprehensible, informal manner for now. + + + + +Definitions +=========== + +A Nim program specifies a computation that acts on a memory consisting of +components called `locations`:idx:. A variable is basically a name for a +location. Each variable and location is of a certain `type`:idx:. The +variable's type is called `static type`:idx:, the location's type is called +`dynamic type`:idx:. If the static type is not the same as the dynamic type, +it is a super-type or subtype of the dynamic type. + +An `identifier`:idx: is a symbol declared as a name for a variable, type, +procedure, etc. The region of the program over which a declaration applies is +called the `scope`:idx: of the declaration. Scopes can be nested. The meaning +of an identifier is determined by the smallest enclosing scope in which the +identifier is declared unless overloading resolution rules suggest otherwise. + +An expression specifies a computation that produces a value or location. +Expressions that produce locations are called `l-values`:idx:. An l-value +can denote either a location or the value the location contains, depending on +the context. Expressions whose values can be determined statically are called +`constant expressions`:idx:; they are never l-values. + +A `static error`:idx: is an error that the implementation detects before +program execution. Unless explicitly classified, an error is a static error. + +A `checked runtime error`:idx: is an error that the implementation detects +and reports at runtime. The method for reporting such errors is via *raising +exceptions* or *dying with a fatal error*. However, the implementation +provides a means to disable these runtime checks. See the section pragmas_ +for details. + +Whether a checked runtime error results in an exception or in a fatal error at +runtime is implementation specific. Thus the following program is always +invalid: + +.. code-block:: nim + var a: array[0..1, char] + let i = 5 + try: + a[i] = 'N' + except IndexError: + echo "invalid index" + +An `unchecked runtime error`:idx: is an error that is not guaranteed to be +detected, and can cause the subsequent behavior of the computation to +be arbitrary. Unchecked runtime errors cannot occur if only `safe`:idx: +language features are used. + + + +Lexical Analysis +================ + +Encoding +-------- + +All Nim source files are in the UTF-8 encoding (or its ASCII subset). Other +encodings are not supported. Any of the standard platform line termination +sequences can be used - the Unix form using ASCII LF (linefeed), the Windows +form using the ASCII sequence CR LF (return followed by linefeed), or the old +Macintosh form using the ASCII CR (return) character. All of these forms can be +used equally, regardless of platform. + + +Indentation +----------- + +Nim's standard grammar describes an `indentation sensitive`:idx: language. +This means that all the control structures are recognized by indentation. +Indentation consists only of spaces; tabulators are not allowed. + +The indentation handling is implemented as follows: The lexer annotates the +following token with the preceding number of spaces; indentation is not +a separate token. This trick allows parsing of Nim with only 1 token of +lookahead. + +The parser uses a stack of indentation levels: the stack consists of integers +counting the spaces. The indentation information is queried at strategic +places in the parser but ignored otherwise: The pseudo terminal ``IND{>}`` +denotes an indentation that consists of more spaces than the entry at the top +of the stack; ``IND{=}`` an indentation that has the same number of spaces. ``DED`` +is another pseudo terminal that describes the *action* of popping a value +from the stack, ``IND{>}`` then implies to push onto the stack. + +With this notation we can now easily define the core of the grammar: A block of +statements (simplified example):: + + ifStmt = 'if' expr ':' stmt + (IND{=} 'elif' expr ':' stmt)* + (IND{=} 'else' ':' stmt)? + + simpleStmt = ifStmt / ... + + stmt = IND{>} stmt ^+ IND{=} DED # list of statements + / simpleStmt # or a simple statement + + + +Comments +-------- + +Comments start anywhere outside a string or character literal with the +hash character ``#``. +Comments consist of a concatenation of `comment pieces`:idx:. A comment piece +starts with ``#`` and runs until the end of the line. The end of line characters +belong to the piece. If the next line only consists of a comment piece with +no other tokens between it and the preceding one, it does not start a new +comment: + + +.. code-block:: nim + i = 0 # This is a single comment over multiple lines. + # The scanner merges these two pieces. + # The comment continues here. + + +`Documentation comments`:idx: are comments that start with two ``##``. +Documentation comments are tokens; they are only allowed at certain places in +the input file as they belong to the syntax tree! + + +Multiline comments +------------------ + +Starting with version 0.13.0 of the language Nim supports multiline comments. +They look like: + +.. code-block:: nim + #[Comment here. + Multiple lines + are not a problem.]# + +Multiline comments support nesting: + +.. code-block:: nim + #[ #[ Multiline comment in already + commented out code. ]# + proc p[T](x: T) = discard + ]# + +Multiline documentation comments also exist and support nesting too: + +.. code-block:: nim + proc foo = + ##[Long documentation comment + here. + ]## + + +Identifiers & Keywords +---------------------- + +Identifiers in Nim can be any string of letters, digits +and underscores, beginning with a letter. Two immediate following +underscores ``__`` are not allowed:: + + letter ::= 'A'..'Z' | 'a'..'z' | '\x80'..'\xff' + digit ::= '0'..'9' + IDENTIFIER ::= letter ( ['_'] (letter | digit) )* + +Currently any Unicode character with an ordinal value > 127 (non ASCII) is +classified as a ``letter`` and may thus be part of an identifier but later +versions of the language may assign some Unicode characters to belong to the +operator characters instead. + +The following keywords are reserved and cannot be used as identifiers: + +.. code-block:: nim + :file: keywords.txt + +Some keywords are unused; they are reserved for future developments of the +language. + + +Identifier equality +------------------- + +Two identifiers are considered equal if the following algorithm returns true: + +.. code-block:: nim + proc sameIdentifier(a, b: string): bool = + a[0] == b[0] and + a.replace("_", "").toLowerAscii == b.replace("_", "").toLowerAscii + +That means only the first letters are compared in a case sensitive manner. Other +letters are compared case insensitively within the ASCII range and underscores are ignored. + +This rather unorthodox way to do identifier comparisons is called +`partial case insensitivity`:idx: and has some advantages over the conventional +case sensitivity: + +It allows programmers to mostly use their own preferred +spelling style, be it humpStyle or snake_style, and libraries written +by different programmers cannot use incompatible conventions. +A Nim-aware editor or IDE can show the identifiers as preferred. +Another advantage is that it frees the programmer from remembering +the exact spelling of an identifier. The exception with respect to the first +letter allows common code like ``var foo: Foo`` to be parsed unambiguously. + +Historically, Nim was a fully `style-insensitive`:idx: language. This meant that +it was not case-sensitive and underscores were ignored and there was no even a +distinction between ``foo`` and ``Foo``. + + +String literals +--------------- + +Terminal symbol in the grammar: ``STR_LIT``. + +String literals can be delimited by matching double quotes, and can +contain the following `escape sequences`:idx:\ : + +================== =================================================== + Escape sequence Meaning +================== =================================================== + ``\p`` platform specific newline: CRLF on Windows, + LF on Unix + ``\r``, ``\c`` `carriage return`:idx: + ``\n``, ``\l`` `line feed`:idx: (often called `newline`:idx:) + ``\f`` `form feed`:idx: + ``\t`` `tabulator`:idx: + ``\v`` `vertical tabulator`:idx: + ``\\`` `backslash`:idx: + ``\"`` `quotation mark`:idx: + ``\'`` `apostrophe`:idx: + ``\`` '0'..'9'+ `character with decimal value d`:idx:; + all decimal digits directly + following are used for the character + ``\a`` `alert`:idx: + ``\b`` `backspace`:idx: + ``\e`` `escape`:idx: `[ESC]`:idx: + ``\x`` HH `character with hex value HH`:idx:; + exactly two hex digits are allowed +================== =================================================== + + +Strings in Nim may contain any 8-bit value, even embedded zeros.

Generalized raw string literals +are especially convenient for embedding mini languages directly into Nim +(for example regular expressions). + +The construct ``identifier"""string literal"""`` exists too. It is a shortcut +for ``identifier("""string literal""")``. + + +Character literals +------------------ + +Character literals are enclosed in single quotes ``''`` and can contain the +same escape sequences as strings - with one exception: the platform +dependent `newline`:idx: (``\p``) +is not allowed as it may be wider than one character (often it is the pair +CR/LF for example).

[: + + +The `slice`:idx: operator `..`:tok: takes precedence over other tokens that +contain a dot: `{..}`:tok: are the three tokens `{`:tok:, `..`:tok:, `}`:tok: +and not the two tokens `{.`:tok:, `.}`:tok:. + + + +Syntax +====== + +This section lists Nim's standard syntax. How the parser handles +the indentation is already described in the `Lexical Analysis`_ section. + +Nim allows user-definable operators. +Binary operators have 11 different levels of precedence. + + + +Associativity +------------- + +Binary operators whose first character is ``^`` are right-associative, all +other binary operators are left-associative. + +.. code-block:: nim + proc `^/`(x, y: float): float = + # a right-associative division operator + result = x / y + echo 12 ^/ 4 ^/ 8 # 24.0 (4 / 8 = 0.5, then 12 / 0.5 = 24.0) + echo 12 / 4 / 8 # 0.375 (12 / 4 = 3.0, then 3 / 8 = 0.375) + +Precedence +---------- + +Unary operators always bind stronger than any binary +operator: ``$a + b`` is ``($a) + b`` and not ``$(a + b)``. + +If an unary operator's first character is ``@`` it is a `sigil-like`:idx: +operator which binds stronger than a ``primarySuffix``: ``@x.abc`` is parsed +as ``(@x).abc`` whereas ``$x.abc`` is parsed as ``$(x.abc)``. + + +For binary operators that are not keywords the precedence is determined by the +following rules: + +Operators ending in either ``->``, ``~>`` or ``=>`` are called +`arrow like`:idx:, and have the lowest precedence of all operators. + +If the operator ends with ``=`` and its first character is none of +``<``, ``>``, ``!``, ``=``, ``~``, ``?``, it is an *assignment operator* which +has the second lowest precedence. + +Otherwise precedence is determined by the first character. + +================ =============================================== ================== =============== +Precedence level Operators First character Terminal symbol +================ =============================================== ================== =============== + 10 (highest) ``$ ^`` OP10 + 9 ``* / div mod shl shr %`` ``* % \ /`` OP9 + 8 ``+ -`` ``+ - ~ |`` OP8 + 7 ``&`` ``&`` OP7 + 6 ``..`` ``.`` OP6 + 5 ``== <= < >= > != in notin is isnot not of`` ``= < > !`` OP5 + 4 ``and`` OP4 + 3 ``or xor`` OP3 + 2 ``@ : ?`` OP2 + 1 *assignment operator* (like ``+=``, ``*=``) OP1 + 0 (lowest) *arrow like operator* (like ``->``, ``=>``) OP0 +================ =============================================== ================== =============== + + +Whether an operator is used a prefix operator is also affected by preceding +whitespace (this parsing change was introduced with version 0.13.0): + +.. code-block:: nim + echo $foo + # is parsed as + echo($foo) + + +Grammar +------- + +The grammar's start symbol is ``module``. + +.. include:: grammar.txt + :literal: + + + +Types +===== + +All expressions have a type which is known at compile time. Nim +is statically typed. One can declare new types, which is in essence defining +an identifier that can be used to denote this custom type. + +These are the major type classes: + +* ordinal types (consist of integer, bool, character, enumeration + (and subranges thereof) types) +* floating point types +* string type +* structured types +* reference (pointer) type +* procedural type +* generic type + + +Ordinal types +------------- +Ordinal types have the following characteristics: + +- Ordinal types are countable and ordered. This property allows + the operation of functions as ``inc``, ``ord``, ``dec`` on ordinal types to + be defined. +- Ordinal values have a smallest possible value. Trying to count further + down than the smallest value gives a checked runtime or static error. +- Ordinal values have a largest possible value. Trying to count further + than the largest value gives a checked runtime or static error. + +Integers, bool, characters and enumeration types (and subranges of these +types) belong to ordinal types. For reasons of simplicity of implementation +the types ``uint`` and ``uint64`` are not ordinal types. + + +Pre-defined integer types +------------------------- +These integer types are pre-defined: + +``int`` + the generic signed integer type; its size is platform dependent and has the + same size as a pointer. This type should be used in general. An integer + literal that has no type suffix is of this type if it is in the range + ``low(int32)..high(int32)`` otherwise the literal's type is ``int64``. + +intXX + additional signed integer types of XX bits use this naming scheme + (example: int16 is a 16 bit wide integer). + The current implementation supports ``int8``, ``int16``, ``int32``, ``int64``. + Literals of these types have the suffix 'iXX. + +``uint`` + the generic `unsigned integer`:idx: type; its size is platform dependent and + has the same size as a pointer. An integer literal with the type + suffix ``'u`` is of this type. + +uintXX + additional signed integer types of XX bits use this naming scheme + (example: uint16 is a 16 bit wide unsigned integer). + The current implementation supports ``uint8``, ``uint16``, ``uint32``, + ``uint64``. Literals of these types have the suffix 'uXX. + Unsigned operations all wrap around; they cannot lead to over- or + underflow errors. + + +In addition to the usual arithmetic operators for signed and unsigned integers +(``+ - *`` etc.) there are also operators that formally work on *signed* +integers but treat their arguments as *unsigned*: They are mostly provided +for backwards compatibility with older versions of the language that lacked +unsigned integer types. These unsigned operations for signed integers use +the ``%`` suffix as convention: + + +====================== ====================================================== +operation meaning +====================== ====================================================== +``a +% b`` unsigned integer addition +``a -% b`` unsigned integer subtraction +``a *% b`` unsigned integer multiplication +``a /% b`` unsigned integer division +``a %% b`` unsigned integer modulo operation +``a <% b`` treat ``a`` and ``b`` as unsigned and compare +``a <=% b`` treat ``a`` and ``b`` as unsigned and compare +``ze(a)`` extends the bits of ``a`` with zeros until it has the + width of the ``int`` type +``toU8(a)`` treats ``a`` as unsigned and converts it to an + unsigned integer of 8 bits (but still the + ``int8`` type) +``toU16(a)`` treats ``a`` as unsigned and converts it to an + unsigned integer of 16 bits (but still the + ``int16`` type) +``toU32(a)`` treats ``a`` as unsigned and converts it to an + unsigned integer of 32 bits (but still the + ``int32`` type) +====================== ====================================================== + +`Automatic type conversion`:idx: is performed in expressions where different +kinds of integer types are used: the smaller type is converted to the larger. + +A `narrowing type conversion`:idx: converts a larger to a smaller type (for +example ``int32 -> int16``. A `widening type conversion`:idx: converts a +smaller type to a larger type (for example ``int16 -> int32``). In Nim only +widening type conversions are *implicit*: + +.. code-block:: nim + var myInt16 = 5i16 + var myInt: int + myInt16 + 34 # of type ``int16`` + myInt16 + myInt # of type ``int`` + myInt16 + 2i32 # of type ``int32`` + +However, ``int`` literals are implicitly convertible to a smaller integer type +if the literal's value fits this smaller type and such a conversion is less +expensive than other implicit conversions, so ``myInt16 + 34`` produces +an ``int16`` result. + +For further details, see `Convertible relation +<#type-relations-convertible-relation>`_. + + +Subrange types +-------------- +A subrange type is a range of values from an ordinal type (the base +type). To define a subrange type, one must specify it's limiting values: the +lowest and highest value of the type: + +.. code-block:: nim + type + Subrange = range[0..5] + + +``Subrange`` is a subrange of an integer which can only hold the values 0 +to 5. Assigning any other value to a variable of type ``Subrange`` is a +checked runtime error (or static error if it can be statically +determined). Assignments from the base type to one of its subrange types +(and vice versa) are allowed. + +A subrange type has the same size as its base type (``int`` in the example). + + +Pre-defined floating point types +-------------------------------- + +The following floating point types are pre-defined: + +``float`` + the generic floating point type; its size is platform dependent + (the compiler chooses the processor's fastest floating point type). + This type should be used in general. + +floatXX + an implementation may define additional floating point types of XX bits using + this naming scheme (example: float64 is a 64 bit wide float). The current + implementation supports ``float32`` and ``float64``. Literals of these types + have the suffix 'fXX. + + +Automatic type conversion in expressions with different kinds +of floating point types is performed: See `Convertible relation`_ for further +details. Arithmetic performed on floating point types follows the IEEE +standard. Integer types are not converted to floating point types automatically +and vice versa. + +The IEEE standard defines five types of floating-point exceptions: + +* Invalid: operations with mathematically invalid operands, + for example 0.0/0.0, sqrt(-1.0), and log(-37.8). +* Division by zero: divisor is zero and dividend is a finite nonzero number, + for example 1.0/0.0. +* Overflow: operation produces a result that exceeds the range of the exponent, + for example MAXDOUBLE+0.0000000000001e308. +* Underflow: operation produces a result that is too small to be represented + as a normal number, for example, MINDOUBLE * MINDOUBLE. +* Inexact: operation produces a result that cannot be represented with infinite + precision, for example, 2.0 / 3.0, log(1.1) and 0.1 in input. + +The IEEE exceptions are either ignored at runtime or mapped to the +Nim exceptions: `FloatInvalidOpError`:idx:, `FloatDivByZeroError`:idx:, +`FloatOverflowError`:idx:, `FloatUnderflowError`:idx:, +and `FloatInexactError`:idx:. +These exceptions inherit from the `FloatingPointError`:idx: base class. + +Nim provides the pragmas `nanChecks`:idx: and `infChecks`:idx: to control +whether the IEEE exceptions are ignored or trap a Nim exception: + +.. code-block:: nim + {.nanChecks: on, infChecks: on.} + var a = 1.0 + var b = 0.0 + echo b / b # raises FloatInvalidOpError + echo a / b # raises FloatOverflowError + +In the current implementation ``FloatDivByZeroError`` and ``FloatInexactError`` +are never raised. ``FloatOverflowError`` is raised instead of +``FloatDivByZeroError``. +There is also a `floatChecks`:idx: pragma that is a short-cut for the +combination of ``nanChecks`` and ``infChecks`` pragmas. ``floatChecks`` are +turned off as default. + +The only operations that are affected by the ``floatChecks`` pragma are +the ``+``, ``-``, ``*``, ``/`` operators for floating point types. + +An implementation should always use the maximum precision available to evaluate +floating pointer values at compile time; this means expressions like +``0.09'f32 + 0.01'f32 == 0.09'f64 + 0.01'f64`` are true. + + +Boolean type +------------ +The boolean type is named `bool`:idx: in Nim and can be one of the two +pre-defined values ``true`` and ``false``. Conditions in ``while``, +``if``, ``elif``, ``when``-statements need to be of type ``bool``. + +This condition holds:: + + ord(false) == 0 and ord(true) == 1 + +The operators ``not, and, or, xor, <, <=, >, >=, !=, ==`` are defined +for the bool type. The ``and`` and ``or`` operators perform short-cut +evaluation. Example: + +.. code-block:: nim + + while p != nil and p.name != "xyz": + # p.name is not evaluated if p == nil + p = p.next + + +The size of the bool type is one byte. + + +Character type +-------------- +The character type is named ``char`` in Nim. Its size is one byte. +Thus it cannot represent an UTF-8 character, but a part of it. +The reason for this is efficiency: for the overwhelming majority of use-cases, +the resulting programs will still handle UTF-8 properly as UTF-8 was specially +designed for this. +Another reason is that Nim can support ``array[char, int]`` or +``set[char]`` efficiently as many algorithms rely on this feature. The +`Rune` type is used for Unicode characters, it can represent any Unicode +character. ``Rune`` is declared in the `unicode module `_. + + + + +Enumeration types +----------------- +Enumeration types define a new type whose values consist of the ones +specified. The values are ordered. Example: + +.. code-block:: nim + + type + Direction = enum + north, east, south, west + + +Now the following holds:: + + ord(north) == 0 + ord(east) == 1 + ord(south) == 2 + ord(west) == 3 + +Thus, north < east < south < west. The comparison operators can be used +with enumeration types. + +For better interfacing to other programming languages, the fields of enum +types can be assigned an explicit ordinal value. However, the ordinal values +have to be in ascending order. A field whose ordinal value is not +explicitly given is assigned the value of the previous field + 1. + +An explicit ordered enum can have *holes*: + +.. code-block:: nim + type + TokenType = enum + a = 2, b = 4, c = 89 # holes are valid + +However, it is then not an ordinal anymore, so it is not possible to use these +enums as an index type for arrays. The procedures ``inc``, ``dec``, ``succ`` +and ``pred`` are not available for them either. + + +The compiler supports the built-in stringify operator ``$`` for enumerations. +The stringify's result can be controlled by explicitly giving the string +values to use: + +.. code-block:: nim + + type + MyEnum = enum + valueA = (0, "my value A"), + valueB = "value B", + valueC = 2, + valueD = (3, "abc") + +As can be seen from the example, it is possible to both specify a field's +ordinal value and its string value by using a tuple. It is also +possible to only specify one of them. + +An enum can be marked with the ``pure`` pragma so that it's fields are not +added to the current scope, so they always need to be accessed +via ``MyEnum.value``: + +.. code-block:: nim + + type + MyEnum {.pure.} = enum + valueA, valueB, valueC, valueD + + echo valueA # error: Unknown identifier + echo MyEnum.valueA # works + + +String type +----------- +All string literals are of the type ``string``. A string in Nim is very +similar to a sequence of characters. However, strings in Nim are both +zero-terminated and have a length field. One can retrieve the length with the +builtin ``len`` procedure; the length never counts the terminating zero. +The assignment operator for strings always copies the string. +The ``&`` operator concatenates strings. + +Most native Nim types support conversion to strings with the special ``$`` proc. +When calling the ``echo`` proc, for example, the built-in stringify operation +for the parameter is called: + +.. code-block:: nim + + echo 3 # calls `$` for `int` + +Whenever a user creates a specialized object, implementation of this procedure +provides for ``string`` representation. + +.. code-block:: nim + type + Person = object + name: string + age: int + + proc `$`(p: Person): string = # `$` always returns a string + result = p.name & " is " & + $p.age & # we *need* the `$` in front of p.age, which + # is natively an integer, to convert it to + # a string + " years old." + +While ``$p.name`` can also be used, the ``$`` operation on a string does +nothing. Note that we cannot rely on automatic conversion from an ``int`` to +a ``string`` like we can for the ``echo`` proc. + +Strings are compared by their lexicographical order. All comparison operators +are available. Strings can be indexed like arrays (lower bound is 0). Unlike +arrays, they can be used in case statements: + +.. code-block:: nim + + case paramStr(i) + of "-v": incl(options, optVerbose) + of "-h", "-?": incl(options, optHelp) + else: write(stdout, "invalid command line option!\n") + +Per convention, all strings are UTF-8 strings, but this is not enforced. For +example, when reading strings from binary files, they are merely a sequence of +bytes. The index operation ``s[i]`` means the i-th *char* of ``s``, not the +i-th *unichar*. The iterator ``runes`` from the `unicode module +`_ can be used for iteration over all Unicode characters. + + +cstring type +------------ + +The ``cstring`` type meaning `compatible string` is the native representation +of a string for the compilation backend. For the C backend the ``cstring`` type +represents a pointer to a zero-terminated char array +compatible to the type ``char*`` in Ansi C. Its primary purpose lies in easy +interfacing with C. The index operation ``s[i]`` means the i-th *char* of +``s``; however no bounds checking for ``cstring`` is performed making the +index operation unsafe. + +A Nim ``string`` is implicitly convertible +to ``cstring`` for convenience. If a Nim string is passed to a C-style +variadic proc, it is implicitly converted to ``cstring`` too: + +.. code-block:: nim + proc printf(formatstr: cstring) {.importc: "printf", varargs, + header: "".} + + printf("This works %s", "as expected") + +Even though the conversion is implicit, it is not *safe*: The garbage collector +does not consider a ``cstring`` to be a root and may collect the underlying +memory. However in practice this almost never happens as the GC considers +stack roots conservatively. One can use the builtin procs ``GC_ref`` and +``GC_unref`` to keep the string data alive for the rare cases where it does +not work. + +A `$` proc is defined for cstrings that returns a string. Thus to get a nim +string from a cstring: + +.. code-block:: nim + var str: string = "Hello!" + var cstr: cstring = str + var newstr: string = $cstr + +Structured types +---------------- +A variable of a structured type can hold multiple values at the same +time. Structured types can be nested to unlimited levels. Arrays, sequences, +tuples, objects and sets belong to the structured types. + +Array and sequence types +------------------------ +Arrays are a homogeneous type, meaning that each element in the array +has the same type. Arrays always have a fixed length which is specified at +compile time (except for open arrays). They can be indexed by any ordinal type. +A parameter ``A`` may be an *open array*, in which case it is indexed by +integers from 0 to ``len(A)-1``. An array expression may be constructed by the +array constructor ``[]``. The element type of this array expression is +inferred from the type of the first element. All other elements need to be +implicitly convertable to this type. + +Sequences are similar to arrays but of dynamic length which may change +during runtime (like strings). Sequences are implemented as growable arrays, +allocating pieces of memory as items are added. A sequence ``S`` is always +indexed by integers from 0 to ``len(S)-1`` and its bounds are checked. +Sequences can be constructed by the array constructor ``[]`` in conjunction +with the array to sequence operator ``@``. Another way to allocate space for a +sequence is to call the built-in ``newSeq`` procedure. + +A sequence may be passed to a parameter that is of type *open array*. + +Example: + +.. code-block:: nim + + type + IntArray = array[0..5, int] # an array that is indexed with 0..5 + IntSeq = seq[int] # a sequence of integers + var + x: IntArray + y: IntSeq + x = [1, 2, 3, 4, 5, 6] # [] is the array constructor + y = @[1, 2, 3, 4, 5, 6] # the @ turns the array into a sequence + + let z = [1.0, 2, 3, 4] # the type of z is array[0..3, float] + +The lower bound of an array or sequence may be received by the built-in proc +``low()``, the higher bound by ``high()``. The length may be +received by ``len()``. ``low()`` for a sequence or an open array always returns +0, as this is the first valid index. +One can append elements to a sequence with the ``add()`` proc or the ``&`` +operator, and remove (and get) the last element of a sequence with the +``pop()`` proc. + +The notation ``x[i]`` can be used to access the i-th element of ``x``. + +Arrays are always bounds checked (at compile-time or at runtime). These +checks can be disabled via pragmas or invoking the compiler with the +``--boundChecks:off`` command line switch. + + +Open arrays +----------- + +Often fixed size arrays turn out to be too inflexible; procedures should +be able to deal with arrays of different sizes. The `openarray`:idx: type +allows this; it can only be used for parameters. Openarrays are always +indexed with an ``int`` starting at position 0. The ``len``, ``low`` +and ``high`` operations are available for open arrays too. Any array with +a compatible base type can be passed to an openarray parameter, the index +type does not matter. In addition to arrays sequences can also be passed +to an open array parameter. + +The openarray type cannot be nested: multidimensional openarrays are not +supported because this is seldom needed and cannot be done efficiently. + +.. code-block:: nim + proc testOpenArray(x: openArray[int]) = echo repr(x) + + testOpenArray([1,2,3]) # array[] + testOpenArray(@[1,2,3]) # seq[] + +Varargs +------- + +A ``varargs`` parameter is an openarray parameter that additionally +allows to pass a variable number of arguments to a procedure. The compiler +converts the list of arguments to an array implicitly: + +.. code-block:: nim + proc myWriteln(f: File, a: varargs[string]) = + for s in items(a): + write(f, s) + write(f, "\n") + + myWriteln(stdout, "abc", "def", "xyz") + # is transformed to: + myWriteln(stdout, ["abc", "def", "xyz"]) + +This transformation is only done if the varargs parameter is the +last parameter in the procedure header. It is also possible to perform +type conversions in this context: + +.. code-block:: nim + proc myWriteln(f: File, a: varargs[string, `$`]) = + for s in items(a): + write(f, s) + write(f, "\n") + + myWriteln(stdout, 123, "abc", 4.0) + # is transformed to: + myWriteln(stdout, [$123, $"def", $4.0]) + +In this example ``$`` is applied to any argument that is passed to the +parameter ``a``. (Note that ``$`` applied to strings is a nop.) + +Note that an explicit array constructor passed to a ``varargs`` parameter is +not wrapped in another implicit array construction: + +.. code-block:: nim + proc takeV[T](a: varargs[T]) = discard + + takeV([123, 2, 1]) # takeV's T is "int", not "array of int" + + +``varargs[typed]`` is treated specially: It matches a variable list of arguments +of arbitrary type but *always* constructs an implicit array. This is required +so that the builtin ``echo`` proc does what is expected: + +.. code-block:: nim + proc echo*(x: varargs[typed, `$`]) {...} + + echo @[1, 2, 3] + # prints "@[1, 2, 3]" and not "123" + + +Tuples and object types +----------------------- +A variable of a tuple or object type is a heterogeneous storage +container. +A tuple or object defines various named *fields* of a type. A tuple also +defines an *order* of the fields. Tuples are meant for heterogeneous storage +types with no overhead and few abstraction possibilities. The constructor ``()`` +can be used to construct tuples. The order of the fields in the constructor +must match the order of the tuple's definition. Different tuple-types are +*equivalent* if they specify the same fields of the same type in the same +order. The *names* of the fields also have to be identical. + +The assignment operator for tuples copies each component. +The default assignment operator for objects copies each component. Overloading +of the assignment operator is described in `type-bound-operations-operator`_. + +.. code-block:: nim + + type + Person = tuple[name: string, age: int] # type representing a person: + # a person consists of a name + # and an age + var + person: Person + person = (name: "Peter", age: 30) + # the same, but less readable: + person = ("Peter", 30) + +The implementation aligns the fields for best access performance. The alignment +is compatible with the way the C compiler does it. + +For consistency with ``object`` declarations, tuples in a ``type`` section +can also be defined with indentation instead of ``[]``: + +.. code-block:: nim + type + Person = tuple # type representing a person + name: string # a person consists of a name + age: natural # and an age + +Objects provide many features that tuples do not. Object provide inheritance +and information hiding. Objects have access to their type at runtime, so that +the ``of`` operator can be used to determine the object's type. The ``of`` operator +is similar to the ``instanceof`` operator in Java. + +.. code-block:: nim + type + Person = object of RootObj + name*: string # the * means that `name` is accessible from other modules + age: int # no * means that the field is hidden + + Student = ref object of Person # a student is a person + id: int # with an id field + + var + student: Student + person: Person + assert(student of Student) # is true + assert(student of Person) # also true + +Object fields that should be visible from outside the defining module, have to +be marked by ``*``. In contrast to tuples, different object types are +never *equivalent*. Objects that have no ancestor are implicitly ``final`` +and thus have no hidden type field. One can use the ``inheritable`` pragma to +introduce new object roots apart from ``system.RootObj``. + + +Object construction +------------------- + +Objects can also be created with an `object construction expression`:idx: that +has the syntax ``T(fieldA: valueA, fieldB: valueB, ...)`` where ``T`` is +an ``object`` type or a ``ref object`` type: + +.. code-block:: nim + var student = Student(name: "Anton", age: 5, id: 3) + +Note that, unlike tuples, objects require the field names along with their values. +For a ``ref object`` type ``system.new`` is invoked implicitly. + + +Object variants +--------------- +Often an object hierarchy is overkill in certain situations where simple +variant types are needed. + +An example: + +.. code-block:: nim + + # This is an example how an abstract syntax tree could be modelled in Nim + type + NodeKind = enum # the different node types + nkInt, # a leaf with an integer value + nkFloat, # a leaf with a float value + nkString, # a leaf with a string value + nkAdd, # an addition + nkSub, # a subtraction + nkIf # an if statement + Node = ref NodeObj + NodeObj = object + case kind: NodeKind # the ``kind`` field is the discriminator + of nkInt: intVal: int + of nkFloat: floatVal: float + of nkString: strVal: string + of nkAdd, nkSub: + leftOp, rightOp: Node + of nkIf: + condition, thenPart, elsePart: Node + + # create a new case object: + var n = Node(kind: nkIf, condition: nil) + # accessing n.thenPart is valid because the ``nkIf`` branch is active: + n.thenPart = Node(kind: nkFloat, floatVal: 2.0) + + # the following statement raises an `FieldError` exception, because + # n.kind's value does not fit and the ``nkString`` branch is not active: + n.strVal = "" + + # invalid: would change the active object branch: + n.kind = nkInt + + var x = Node(kind: nkAdd, leftOp: Node(kind: nkInt, intVal: 4), + rightOp: Node(kind: nkInt, intVal: 2)) + # valid: does not change the active object branch: + x.kind = nkSub + +As can been seen from the example, an advantage to an object hierarchy is that +no casting between different object types is needed. Yet, access to invalid +object fields raises an exception. + +The syntax of ``case`` in an object declaration follows closely the syntax of +the ``case`` statement: The branches in a ``case`` section may be indented too. + +In the example the ``kind`` field is called the `discriminator`:idx:\: For +safety its address cannot be taken and assignments to it are restricted: The +new value must not lead to a change of the active object branch. For an object +branch switch ``system.reset`` has to be used. Also, when the fields of a +particular branch are specified during object construction, the correct value +for the discriminator must be supplied at compile-time. + +Package level objects +--------------------- + +Every Nim module resides in a (nimble) package. An object type can be attached +to the package it resides in. If that is done, the type can be referenced from +other modules as an `incomplete`:idx: object type. This features allows to +break up recursive type dependencies accross module boundaries. Incomplete +object types are always passed ``byref`` and can only be used in pointer like +contexts (``var/ref/ptr IncompleteObject``) in general since the compiler does +not yet know the size of the object. To complete an incomplete object +the ``package`` pragma has to be used. ``package`` implies ``byref``. + +As long as a type ``T`` is incomplete ``sizeof(T)`` or "runtime type +information" for ``T`` is not available. + + +Example: + +.. code-block:: nim + + # module A (in an arbitrary package) + type + Pack.SomeObject = object ## declare as incomplete object of package 'Pack' + Triple = object + a, b, c: ref SomeObject ## pointers to incomplete objects are allowed + + ## Incomplete objects can be used as parameters: + proc myproc(x: SomeObject) = discard + + +.. code-block:: nim + + # module B (in package "Pack") + type + SomeObject* {.package.} = object ## Use 'package' to complete the object + s, t: string + x, y: int + + +Set type +-------- + +.. include:: sets_fragment.txt + +Reference and pointer types +--------------------------- +References (similar to pointers in other programming languages) are a +way to introduce many-to-one relationships. This means different references can +point to and modify the same location in memory (also called `aliasing`:idx:). + +Nim distinguishes between `traced`:idx: and `untraced`:idx: references. +Untraced references are also called *pointers*. Traced references point to +objects of a garbage collected heap, untraced references point to +manually allocated objects or to objects somewhere else in memory. Thus +untraced references are *unsafe*. However for certain low-level operations +(accessing the hardware) untraced references are unavoidable. + +Traced references are declared with the **ref** keyword, untraced references +are declared with the **ptr** keyword. In general, a `ptr T` is implicitly +convertible to the `pointer` type. + +An empty subscript ``[]`` notation can be used to derefer a reference, +the ``addr`` procedure returns the address of an item. An address is always +an untraced reference. +Thus the usage of ``addr`` is an *unsafe* feature. + +The ``.`` (access a tuple/object field operator) +and ``[]`` (array/string/sequence index operator) operators perform implicit +dereferencing operations for reference types: + +.. code-block:: nim + + type + Node = ref NodeObj + NodeObj = object + le, ri: Node + data: int + + var + n: Node + new(n) + n.data = 9 + # no need to write n[].data; in fact n[].data is highly discouraged! + +Automatic dereferencing is also performed for the first argument of a routine +call. But currently this feature has to be only enabled +via ``{.experimental.}``: + +.. code-block:: nim + {.experimental.} + + proc depth(x: NodeObj): int = ... + + var + n: Node + new(n) + echo n.depth + # no need to write n[].depth either + + + +In order to simplify structural type checking, recursive tuples are not valid: + +.. code-block:: nim + # invalid recursion + type MyTuple = tuple[a: ref MyTuple] + +Likewise ``T = ref T`` is an invalid type. + +As a syntactical extension ``object`` types can be anonymous if +declared in a type section via the ``ref object`` or ``ptr object`` notations. +This feature is useful if an object should only gain reference semantics: + +.. code-block:: nim + + type + Node = ref object + le, ri: Node + data: int + + +To allocate a new traced object, the built-in procedure ``new`` has to be used. +To deal with untraced memory, the procedures ``alloc``, ``dealloc`` and +``realloc`` can be used. The documentation of the system module contains +further information. + +If a reference points to *nothing*, it has the value ``nil``. + +Special care has to be taken if an untraced object contains traced objects like +traced references, strings or sequences: in order to free everything properly, +the built-in procedure ``GCunref`` has to be called before freeing the untraced +memory manually: + +.. code-block:: nim + type + Data = tuple[x, y: int, s: string] + + # allocate memory for Data on the heap: + var d = cast[ptr Data](alloc0(sizeof(Data))) + + # create a new string on the garbage collected heap: + d.s = "abc" + + # tell the GC that the string is not needed anymore: + GCunref(d.s) + + # free the memory: + dealloc(d) + +Without the ``GCunref`` call the memory allocated for the ``d.s`` string would +never be freed. The example also demonstrates two important features for low +level programming: the ``sizeof`` proc returns the size of a type or value +in bytes. The ``cast`` operator can circumvent the type system: the compiler +is forced to treat the result of the ``alloc0`` call (which returns an untyped +pointer) as if it would have the type ``ptr Data``. Casting should only be +done if it is unavoidable: it breaks type safety and bugs can lead to +mysterious crashes. + +**Note**: The example only works because the memory is initialized to zero +(``alloc0`` instead of ``alloc`` does this): ``d.s`` is thus initialized to +``nil`` which the string assignment can handle. One needs to know low level +details like this when mixing garbage collected data with unmanaged memory. + +.. XXX finalizers for traced objects + + +Not nil annotation +------------------ + +All types for that ``nil`` is a valid value can be annotated to +exclude ``nil`` as a valid value with the ``not nil`` annotation: + +.. code-block:: nim + type + PObject = ref TObj not nil + TProc = (proc (x, y: int)) not nil + + proc p(x: PObject) = + echo "not nil" + + # compiler catches this: + p(nil) + + # and also this: + var x: PObject + p(x) + +The compiler ensures that every code path initializes variables which contain +non nilable pointers. The details of this analysis are still to be specified +here. + + +Memory regions +-------------- + +The types ``ref`` and ``ptr`` can get an optional ``region`` annotation. +A region has to be an object type. + +Regions are very useful to separate user space and kernel memory in the +development of OS kernels: + +.. code-block:: nim + type + Kernel = object + Userspace = object + + var a: Kernel ptr Stat + var b: Userspace ptr Stat + + # the following does not compile as the pointer types are incompatible: + a = b + +As the example shows ``ptr`` can also be used as a binary +operator, ``region ptr T`` is a shortcut for ``ptr[region, T]``. + +In order to make generic code easier to write ``ptr T`` is a subtype +of ``ptr[R, T]`` for any ``R``. + +Furthermore the subtype relation of the region object types is lifted to +the pointer types: If ``A <: B`` then ``ptr[A, T] <: ptr[B, T]``. This can be +used to model subregions of memory. As a special typing rule ``ptr[R, T]`` is +not compatible to ``pointer`` to prevent the following from compiling: + +.. code-block:: nim + # from system + proc dealloc(p: pointer) + + # wrap some scripting language + type + PythonsHeap = object + PyObjectHeader = object + rc: int + typ: pointer + PyObject = ptr[PythonsHeap, PyObjectHeader] + + proc createPyObject(): PyObject {.importc: "...".} + proc destroyPyObject(x: PyObject) {.importc: "...".} + + var foo = createPyObject() + # type error here, how convenient: + dealloc(foo) + + +Future directions: + +* Memory regions might become available for ``string`` and ``seq`` too. +* Builtin regions like ``private``, ``global`` and ``local`` might be + useful for an OpenCL target. +* Builtin "regions" can model ``lent`` and ``unique`` pointers. +* An assignment operator can be attached to a region so that proper write + barriers can be generated. This would imply that the GC can be implemented + completely in user-space. + + +Procedural type +--------------- +A procedural type is internally a pointer to a procedure. ``nil`` is +an allowed value for variables of a procedural type. Nim uses procedural +types to achieve `functional`:idx: programming techniques. + +Examples: + +.. code-block:: nim + + proc printItem(x: int) = ... + + proc forEach(c: proc (x: int) {.cdecl.}) = + ... + + forEach(printItem) # this will NOT compile because calling conventions differ + + +.. code-block:: nim + + type + OnMouseMove = proc (x, y: int) {.closure.} + + proc onMouseMove(mouseX, mouseY: int) = + # has default calling convention + echo "x: ", mouseX, " y: ", mouseY + + proc setOnMouseMove(mouseMoveEvent: OnMouseMove) = discard + + # ok, 'onMouseMove' has the default calling convention, which is compatible + # to 'closure': + setOnMouseMove(onMouseMove) + + +A subtle issue with procedural types is that the calling convention of the +procedure influences the type compatibility: procedural types are only +compatible if they have the same calling convention. As a special extension, +a procedure of the calling convention ``nimcall`` can be passed to a parameter +that expects a proc of the calling convention ``closure``. + +Nim supports these `calling conventions`:idx:\: + +`nimcall`:idx: + is the default convention used for a Nim **proc**. It is the + same as ``fastcall``, but only for C compilers that support ``fastcall``. + +`closure`:idx: + is the default calling convention for a **procedural type** that lacks + any pragma annotations. It indicates that the procedure has a hidden + implicit parameter (an *environment*). Proc vars that have the calling + convention ``closure`` take up two machine words: One for the proc pointer + and another one for the pointer to implicitly passed environment. + +`stdcall`:idx: + This the stdcall convention as specified by Microsoft. The generated C + procedure is declared with the ``__stdcall`` keyword. + +`cdecl`:idx: + The cdecl convention means that a procedure shall use the same convention + as the C compiler. Under windows the generated C procedure is declared with + the ``__cdecl`` keyword. + +`safecall`:idx: + This is the safecall convention as specified by Microsoft. The generated C + procedure is declared with the ``__safecall`` keyword. The word *safe* + refers to the fact that all hardware registers shall be pushed to the + hardware stack. + +`inline`:idx: + The inline convention means the the caller should not call the procedure, + but inline its code directly. Note that Nim does not inline, but leaves + this to the C compiler; it generates ``__inline`` procedures. This is + only a hint for the compiler: it may completely ignore it and + it may inline procedures that are not marked as ``inline``. + +`fastcall`:idx: + Fastcall means different things to different C compilers. One gets whatever + the C ``__fastcall`` means. + +`syscall`:idx: + The syscall convention is the same as ``__syscall`` in C. It is used for + interrupts. + +`noconv`:idx: + The generated C code will not have any explicit calling convention and thus + use the C compiler's default calling convention. This is needed because + Nim's default calling convention for procedures is ``fastcall`` to + improve speed. + +Most calling conventions exist only for the Windows 32-bit platform. + +The default calling convention is ``nimcall``, unless it is an inner proc (a +proc inside of a proc). For an inner proc an analysis is performed whether it +accesses its environment. If it does so, it has the calling convention +``closure``, otherwise it has the calling convention ``nimcall``. + + +Distinct type +------------- + +A ``distinct`` type is new type derived from a `base type`:idx: that is +incompatible with its base type. In particular, it is an essential property +of a distinct type that it **does not** imply a subtype relation between it +and its base type. Explicit type conversions from a distinct type to its +base type and vice versa are allowed. + + +Modelling currencies +~~~~~~~~~~~~~~~~~~~~ + +A distinct type can be used to model different physical `units`:idx: with a +numerical base type, for example. The following example models currencies. + +Different currencies should not be mixed in monetary calculations. Distinct +types are a perfect tool to model different currencies: + +.. code-block:: nim + type + Dollar = distinct int + Euro = distinct int + + var + d: Dollar + e: Euro + + echo d + 12 + # Error: cannot add a number with no unit and a ``Dollar`` + +Unfortunately, ``d + 12.Dollar`` is not allowed either, +because ``+`` is defined for ``int`` (among others), not for ``Dollar``. So +a ``+`` for dollars needs to be defined: + +.. code-block:: + proc `+` (x, y: Dollar): Dollar = + result = Dollar(int(x) + int(y)) + +It does not make sense to multiply a dollar with a dollar, but with a +number without unit; and the same holds for division: + +.. code-block:: + proc `*` (x: Dollar, y: int): Dollar = + result = Dollar(int(x) * y) + + proc `*` (x: int, y: Dollar): Dollar = + result = Dollar(x * int(y)) + + proc `div` ... + +This quickly gets tedious. The implementations are trivial and the compiler +should not generate all this code only to optimize it away later - after all +``+`` for dollars should produce the same binary code as ``+`` for ints. +The pragma `borrow`:idx: has been designed to solve this problem; in principle +it generates the above trivial implementations: + +.. code-block:: nim + proc `*` (x: Dollar, y: int): Dollar {.borrow.} + proc `*` (x: int, y: Dollar): Dollar {.borrow.} + proc `div` (x: Dollar, y: int): Dollar {.borrow.} + +The ``borrow`` pragma makes the compiler use the same implementation as +the proc that deals with the distinct type's base type, so no code is +generated. + +But it seems all this boilerplate code needs to be repeated for the ``Euro`` +currency. This can be solved with templates_. + +.. code-block:: nim + template additive(typ: typedesc) = + proc `+` *(x, y: typ): typ {.borrow.} + proc `-` *(x, y: typ): typ {.borrow.} + + # unary operators: + proc `+` *(x: typ): typ {.borrow.} + proc `-` *(x: typ): typ {.borrow.} + + template multiplicative(typ, base: typedesc) = + proc `*` *(x: typ, y: base): typ {.borrow.} + proc `*` *(x: base, y: typ): typ {.borrow.} + proc `div` *(x: typ, y: base): typ {.borrow.} + proc `mod` *(x: typ, y: base): typ {.borrow.} + + template comparable(typ: typedesc) = + proc `<` * (x, y: typ): bool {.borrow.} + proc `<=` * (x, y: typ): bool {.borrow.} + proc `==` * (x, y: typ): bool {.borrow.} + + template defineCurrency(typ, base: untyped) = + type + typ* = distinct base + additive(typ) + multiplicative(typ, base) + comparable(typ) + + defineCurrency(Dollar, int) + defineCurrency(Euro, int) + + +The borrow pragma can also be used to annotate the distinct type to allow +certain builtin operations to be lifted: + +.. code-block:: nim + type + Foo = object + a, b: int + s: string + + Bar {.borrow: `.`.} = distinct Foo + + var bb: ref Bar + new bb + # field access now valid + bb.a = 90 + bb.s = "abc" + +Currently only the dot accessor can be borrowed in this way. + + +Avoiding SQL injection attacks +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +An SQL statement that is passed from Nim to an SQL database might be +modelled as a string. However, using string templates and filling in the +values is vulnerable to the famous `SQL injection attack`:idx:\: + +.. code-block:: nim + import strutils + + proc query(db: DbHandle, statement: string) = ... + + var + username: string + + db.query("SELECT FROM users WHERE name = '$1'" % username) + # Horrible security hole, but the compiler does not mind! + +This can be avoided by distinguishing strings that contain SQL from strings +that don't. Distinct types provide a means to introduce a new string type +``SQL`` that is incompatible with ``string``: + +.. code-block:: nim + type + SQL = distinct string + + proc query(db: DbHandle, statement: SQL) = ... + + var + username: string + + db.query("SELECT FROM users WHERE name = '$1'" % username) + # Error at compile time: `query` expects an SQL string! + + +It is an essential property of abstract types that they **do not** imply a +subtype relation between the abstract type and its base type. Explicit type +conversions from ``string`` to ``SQL`` are allowed: + +.. code-block:: nim + import strutils, sequtils + + proc properQuote(s: string): SQL = + # quotes a string properly for an SQL statement + return SQL(s) + + proc `%` (frmt: SQL, values: openarray[string]): SQL = + # quote each argument: + let v = values.mapIt(SQL, properQuote(it)) + # we need a temporary type for the type conversion :-( + type StrSeq = seq[string] + # call strutils.`%`: + result = SQL(string(frmt) % StrSeq(v)) + + db.query("SELECT FROM users WHERE name = '$1'".SQL % [username]) + +Now we have compile-time checking against SQL injection attacks. Since +``"".SQL`` is transformed to ``SQL("")`` no new syntax is needed for nice +looking ``SQL`` string literals. The hypothetical ``SQL`` type actually +exists in the library as the `TSqlQuery type `_ of +modules like `db_sqlite `_. + + +Void type +--------- + +The ``void`` type denotes the absence of any type. Parameters of +type ``void`` are treated as non-existent, ``void`` as a return type means that +the procedure does not return a value: + +.. code-block:: nim + proc nothing(x, y: void): void = + echo "ha" + + nothing() # writes "ha" to stdout + +The ``void`` type is particularly useful for generic code: + +.. code-block:: nim + proc callProc[T](p: proc (x: T), x: T) = + when T is void: + p() + else: + p(x) + + proc intProc(x: int) = discard + proc emptyProc() = discard + + callProc[int](intProc, 12) + callProc[void](emptyProc) + +However, a ``void`` type cannot be inferred in generic code: + +.. code-block:: nim + callProc(emptyProc) + # Error: type mismatch: got (proc ()) + # but expected one of: + # callProc(p: proc (T), x: T) + +The ``void`` type is only valid for parameters and return types; other symbols +cannot have the type ``void``. + + +Auto type +--------- + +The ``auto`` type can only be used for return types and parameters. For return +types it causes the compiler to infer the type from the routine body: + +.. code-block:: nim + proc returnsInt(): auto = 1984 + +For parameters it currently creates implicitly generic routines: + +.. code-block:: nim + proc foo(a, b: auto) = discard + +Is the same as: + +.. code-block:: nim + proc foo[T1, T2](a: T1, b: T2) = discard + +However later versions of the language might change this to mean "infer the +parameters' types from the body". Then the above ``foo`` would be rejected as +the parameters' types can not be inferred from an empty ``discard`` statement. + + +Type relations +============== + +The following section defines several relations on types that are needed to +describe the type checking done by the compiler. + + +Type equality +------------- +Nim uses structural type equivalence for most types. Only for objects, +enumerations and distinct types name equivalence is used.

XXX nil is a special value! + + +Covariance +---------- + +Covariance in Nim can be introduced only though pointer-like types such +as ``ptr`` and ``ref``. Sequence, Array and OpenArray types, instantiated +with pointer-like types will be considered covariant if and only if they +are also immutable. The introduction of a ``var`` modifier or additional +``ptr`` or ``ref`` indirections would result in invariant treatment of +these types. + +``proc`` types are currently always invariant, but future versions of Nim +may relax this rule. + +User-defined generic types may also be covariant with respect to some of +their parameters. By default, all generic params are considered invariant, +but you may choose the apply the prefix modifier ``in`` to a parameter to +make it contravariant or ``out`` to make it covariant: + +.. code-block:: nim + type + AnnotatedPtr[out T] = + metadata: MyTypeInfo + p: ref T + + RingBuffer[out T] = + startPos: int + data: seq[T] + + Action {.importcpp: "std::function".} [in T] = object + +When the designated generic parameter is used to instantiate a pointer-like +type as in the case of `AnnotatedPtr` above, the resulting generic type will +also have pointer-like covariance: + +.. code-block:: nim + type + GuiWidget = object of RootObj + Button = object of GuiWidget + ComboBox = object of GuiWidget + + var + widgetPtr: AnnotatedPtr[GuiWidget] + buttonPtr: AnnotatedPtr[Button] + + ... + + proc drawWidget[T](x: AnnotatedPtr[GuiWidget]) = ... + + # you can call procs expecting base types by supplying a derived type + drawWidget(buttonPtr) + + # and you can convert more-specific pointer types to more general ones + widgetPtr = buttonPtr + +Just like with regular pointers, covariance will be enabled only for immutable +values: + +.. code-block:: nim + proc makeComboBox[T](x: var AnnotatedPtr[GuiWidget]) = + x.p = new(ComboBox) + + makeComboBox(buttonPtr) # Error, AnnotatedPtr[Button] cannot be modified + # to point to a ComboBox + +On the other hand, in the `RingBuffer` example above, the designated generic +param is used to instantiate the non-pointer ``seq`` type, which means that +the resulting generic type will have covariance that mimics an array or +sequence (i.e. it will be covariant only when instantiated with ``ptr`` and +``ref`` types): + +.. code-block:: nim + + type + Base = object of RootObj + Derived = object of Base + + proc consumeBaseValues(b: RingBuffer[Base]) = ... + + var derivedValues: RingBuffer[Derived] + + consumeBaseValues(derivedValues) # Error, Base and Derived values may differ + # in size + + proc consumeBasePointers(b: RingBuffer[ptr Base]) = ... + + var derivedPointers: RingBuffer[ptr Derived] + + consumeBaseValues(derivedPointers) # This is legal + +Please note that Nim will treat the user-defined pointer-like types as +proper alternatives to the built-in pointer types. That is, types such +as `seq[AnnotatedPtr[T]]` or `RingBuffer[AnnotatedPtr[T]]` will also be +considered covariant and you can create new pointer-like types by instantiating +other user-defined pointer-like types. + +The contravariant parameters introduced with the ``in`` modifier are currently +useful only when interfacing with imported types having such semantics. + + +Convertible relation +-------------------- +A type ``a`` is **implicitly** convertible to type ``b`` iff the following +algorithm returns true: + +.. code-block:: nim + # XXX range types? + proc isImplicitlyConvertible(a, b: PType): bool = + if isSubtype(a, b) or isCovariant(a, b): + return true + case a.kind + of int: result = b in {int8, int16, int32, int64, uint, uint8, uint16, + uint32, uint64, float, float32, float64} + of int8: result = b in {int16, int32, int64, int} + of int16: result = b in {int32, int64, int} + of int32: result = b in {int64, int} + of uint: result = b in {uint32, uint64} + of uint8: result = b in {uint16, uint32, uint64} + of uint16: result = b in {uint32, uint64} + of uint32: result = b in {uint64} + of float: result = b in {float32, float64} + of float32: result = b in {float64, float} + of float64: result = b in {float32, float} + of seq: + result = b == openArray and typeEquals(a.baseType, b.baseType) + of array: + result = b == openArray and typeEquals(a.baseType, b.baseType) + if a.baseType == char and a.indexType.rangeA == 0: + result = b = cstring + of cstring, ptr: + result = b == pointer + of string: + result = b == cstring + +A type ``a`` is **explicitly** convertible to type ``b`` iff the following +algorithm returns true: + +.. code-block:: nim + proc isIntegralType(t: PType): bool = + result = isOrdinal(t) or t.kind in {float, float32, float64} + + proc isExplicitlyConvertible(a, b: PType): bool = + result = false + if isImplicitlyConvertible(a, b): return true + if typeEqualsOrDistinct(a, b): return true + if isIntegralType(a) and isIntegralType(b): return true + if isSubtype(a, b) or isSubtype(b, a): return true + +The convertible relation can be relaxed by a user-defined type +`converter`:idx:. + +.. code-block:: nim + converter toInt(x: char): int = result = ord(x) + + var + x: int + chr: char = 'a' + + # implicit conversion magic happens here + x = chr + echo x # => 97 + # you can use the explicit form too + x = chr.toInt + echo x # => 97 + +The type conversion ``T(a)`` is an L-value if ``a`` is an L-value and +``typeEqualsOrDistinct(T, type(a))`` holds. + + +Assignment compatibility +------------------------ + +An expression ``b`` can be assigned to an expression ``a`` iff ``a`` is an +`l-value` and ``isImplicitlyConvertible(b.typ, a.typ)`` holds. + + +Overloading resolution +====================== + +In a call ``p(args)`` the routine ``p`` that matches best is selected. If +multiple routines match equally well, the ambiguity is reported at compiletime. + +Every arg in args needs to match. There are multiple different categories how an +argument can match. Let ``f`` be the formal parameter's type and ``a`` the type +of the argument. + +1. Exact match: ``a`` and ``f`` are of the same type. +2. Literal match: ``a`` is an integer literal of value ``v`` + and ``f`` is a signed or unsigned integer type and ``v`` is in ``f``'s + range. Or: ``a`` is a floating point literal of value ``v`` + and ``f`` is a floating point type and ``v`` is in ``f``'s + range. +3. Generic match: ``f`` is a generic type and ``a`` matches, for + instance ``a`` is ``int`` and ``f`` is a generic (constrained) parameter + type (like in ``[T]`` or ``[T: int|char]``. +4. Subrange or subtype match: ``a`` is a ``range[T]`` and ``T`` + matches ``f`` exactly. Or: ``a`` is a subtype of ``f``. +5. Integral conversion match: ``a`` is convertible to ``f`` and ``f`` and ``a`` + is some integer or floating point type. +6. Conversion match: ``a`` is convertible to ``f``, possibly via a user + defined ``converter``. + +These matching categories have a priority: An exact match is better than a +literal match and that is better than a generic match etc. In the following +``count(p, m)`` counts the number of matches of the matching category ``m`` +for the routine ``p``. + +A routine ``p`` matches better than a routine ``q`` if the following +algorithm returns true:: + + for each matching category m in ["exact match", "literal match", + "generic match", "subtype match", + "integral match", "conversion match"]: + if count(p, m) > count(q, m): return true + elif count(p, m) == count(q, m): + discard "continue with next category m" + else: + return false + return "ambiguous" + + +Some examples: + +.. code-block:: nim + proc takesInt(x: int) = echo "int" + proc takesInt[T](x: T) = echo "T" + proc takesInt(x: int16) = echo "int16" + + takesInt(4) # "int" + var x: int32 + takesInt(x) # "T" + var y: int16 + takesInt(y) # "int16" + var z: range[0..4] = 0 + takesInt(z) # "T" + + +If this algorithm returns "ambiguous" further disambiguation is performed: +If the argument ``a`` matches both the parameter type ``f`` of ``p`` +and ``g`` of ``q`` via a subtyping relation, the inheritance depth is taken +into account: + +.. code-block:: nim + type + A = object of RootObj + B = object of A + C = object of B + + proc p(obj: A) = + echo "A" + + proc p(obj: B) = + echo "B" + + var c = C() + # not ambiguous, calls 'B', not 'A' since B is a subtype of A + # but not vice versa: + p(c) + + proc pp(obj: A, obj2: B) = echo "A B" + proc pp(obj: B, obj2: A) = echo "B A" + + # but this is ambiguous: + pp(c, c) + + +Likewise for generic matches the most specialized generic type (that still +matches) is preferred: + +.. code-block:: nim + proc gen[T](x: ref ref T) = echo "ref ref T" + proc gen[T](x: ref T) = echo "ref T" + proc gen[T](x: T) = echo "T" + + var ri: ref int + gen(ri) # "ref T" + + +Overloading based on 'var T' +---------------------------- + +If the formal parameter ``f`` is of type ``var T`` in addition to the ordinary +type checking, the argument is checked to be an `l-value`:idx:. ``var T`` +matches better than just ``T`` then. + +.. code-block:: nim + proc sayHi(x: int): string = + # matches a non-var int + result = $x + proc sayHi(x: var int): string = + # matches a var int + result = $(x + 10) + + proc sayHello(x: int) = + var m = x # a mutable version of x + echo sayHi(x) # matches the non-var version of sayHi + echo sayHi(m) # matches the var version of sayHi + + sayHello(3) # 3 + # 13 + +Automatic dereferencing +----------------------- + +If the `experimental mode <#pragmas-experimental-pragma>`_ is active and no other match +is found, the first argument ``a`` is dereferenced automatically if it's a +pointer type and overloading resolution is tried with ``a[]`` instead. + +Automatic self insertions +------------------------- + +Starting with version 0.14 of the language, Nim supports ``field`` as a +shortcut for ``self.field`` comparable to the `this`:idx: keyword in Java +or C++. This feature has to be explicitly enabled via a ``{.this: self.}`` +statement pragma. This pragma is active for the rest of the module: + +.. code-block:: nim + type + Parent = object of RootObj + parentField: int + Child = object of Parent + childField: int + + {.this: self.} + proc sumFields(self: Child): int = + result = parentField + childField + # is rewritten to: + # result = self.parentField + self.childField + +Instead of ``self`` any other identifier can be used too, but +``{.this: self.}`` will become the default directive for the whole language +eventually. + +In addition to fields, routine applications are also rewritten, but only +if no other interpretation of the call is possible: + +.. code-block:: nim + proc test(self: Child) = + echo childField, " ", sumFields() + # is rewritten to: + echo self.childField, " ", sumFields(self) + # but NOT rewritten to: + echo self, self.childField, " ", sumFields(self) + + +Lazy type resolution for untyped +-------------------------------- + +**Note**: An `unresolved`:idx: expression is an expression for which no symbol +lookups and no type checking have been performed. + +Since templates and macros that are not declared as ``immediate`` participate +in overloading resolution it's essential to have a way to pass unresolved +expressions to a template or macro. This is what the meta-type ``untyped`` +accomplishes: + +.. code-block:: nim + template rem(x: untyped) = discard + + rem unresolvedExpression(undeclaredIdentifier) + +A parameter of type ``untyped`` always matches any argument (as long as there is +any argument passed to it). + +But one has to watch out because other overloads might trigger the +argument's resolution: + +.. code-block:: nim + template rem(x: untyped) = discard + proc rem[T](x: T) = discard + + # undeclared identifier: 'unresolvedExpression' + rem unresolvedExpression(undeclaredIdentifier) + +``untyped`` and ``varargs[untyped]`` are the only metatype that are lazy in this sense, the other +metatypes ``typed`` and ``typedesc`` are not lazy. + + +Varargs matching +---------------- + +See `Varargs <#types-varargs>`_. + + +Statements and expressions +========================== + +Nim uses the common statement/expression paradigm: Statements do not +produce a value in contrast to expressions. However, some expressions are +statements. + +Statements are separated into `simple statements`:idx: and +`complex statements`:idx:. +Simple statements are statements that cannot contain other statements like +assignments, calls or the ``return`` statement; complex statements can +contain other statements. To avoid the `dangling else problem`:idx:, complex +statements always have to be indented. The details can be found in the grammar. + + +Statement list expression +------------------------- + +Statements can also occur in an expression context that looks +like ``(stmt1; stmt2; ...; ex)``. This is called +an statement list expression or ``(;)``. The type +of ``(stmt1; stmt2; ...; ex)`` is the type of ``ex``. All the other statements +must be of type ``void``. (One can use ``discard`` to produce a ``void`` type.) +``(;)`` does not introduce a new scope. + + +Discard statement +----------------- + +Example: + +.. code-block:: nim + proc p(x, y: int): int = + result = x + y + + discard p(3, 4) # discard the return value of `p` + +The ``discard`` statement evaluates its expression for side-effects and +throws the expression's resulting value away. + +Ignoring the return value of a procedure without using a discard statement is +a static error. + +The return value can be ignored implicitly if the called proc/iterator has +been declared with the `discardable`:idx: pragma: + +.. code-block:: nim + proc p(x, y: int): int {.discardable.} = + result = x + y + + p(3, 4) # now valid + +An empty ``discard`` statement is often used as a null statement: + +.. code-block:: nim + proc classify(s: string) = + case s[0] + of SymChars, '_': echo "an identifier" + of '0'..'9': echo "a number" + else: discard + + +Void context +------------ + +In a list of statements every expression except the last one needs to have the +type ``void``. In addition to this rule an assignment to the builtin ``result`` +symbol also triggers a mandatory ``void`` context for the subsequent expressions: + +.. code-block:: nim + proc invalid*(): string = + result = "foo" + "invalid" # Error: value of type 'string' has to be discarded + +.. code-block:: nim + proc valid*(): string = + let x = 317 + "valid" + + +Var statement +------------- + +Var statements declare new local and global variables and +initialize them. A comma separated list of variables can be used to specify +variables of the same type: + +.. code-block:: nim + + var + a: int = 0 + x, y, z: int + +If an initializer is given the type can be omitted: the variable is then of the +same type as the initializing expression. Variables are always initialized +with a default value if there is no initializing expression. The default +value depends on the type and is always a zero in binary. + +============================ ============================================== +Type default value +============================ ============================================== +any integer type 0 +any float 0.0 +char '\\0' +bool false +ref or pointer type nil +procedural type nil +sequence nil (*not* ``@[]``) +string nil (*not* "") +tuple[x: A, y: B, ...] (default(A), default(B), ...) + (analogous for objects) +array[0..., T] [default(T), ...] +range[T] default(T); this may be out of the valid range +T = enum cast[T](0); this may be an invalid value +============================ ============================================== + + +The implicit initialization can be avoided for optimization reasons with the +`noinit`:idx: pragma: + +.. code-block:: nim + var + a {.noInit.}: array [0..1023, char] + +If a proc is annotated with the ``noinit`` pragma this refers to its implicit +``result`` variable: + +.. code-block:: nim + proc returnUndefinedValue: int {.noinit.} = discard + + +The implicit initialization can be also prevented by the `requiresInit`:idx: +type pragma. The compiler requires an explicit initialization for the object +and all of its fields. However it does a `control flow analysis`:idx: to prove +the variable has been initialized and does not rely on syntactic properties: + +.. code-block:: nim + type + MyObject = object {.requiresInit.} + + proc p() = + # the following is valid: + var x: MyObject + if someCondition(): + x = a() + else: + x = a() + # use x + + +let statement +------------- + +A ``let`` statement declares new local and global `single assignment`:idx: +variables and binds a value to them. The syntax is the same as that of the ``var`` +statement, except that the keyword ``var`` is replaced by the keyword ``let``. +Let variables are not l-values and can thus not be passed to ``var`` parameters +nor can their address be taken. They cannot be assigned new values. + +For let variables the same pragmas are available as for ordinary variables. + + +Tuple unpacking +--------------- + +In a ``var`` or ``let`` statement tuple unpacking can be performed. The special +identifier ``_`` can be used to ignore some parts of the tuple: + +.. code-block:: nim + proc returnsTuple(): (int, int, int) = (4, 2, 3) + + let (x, _, z) = returnsTuple() + + + +Const section +------------- + +`Constants`:idx: are symbols which are bound to a value. The constant's value +cannot change. The compiler must be able to evaluate the expression in a +constant declaration at compile time. + +Nim contains a sophisticated compile-time evaluator, so procedures which +have no side-effect can be used in constant expressions too: + +.. code-block:: nim + import strutils + const + constEval = contains("abc", 'b') # computed at compile time! + + +The rules for compile-time computability are: + +1. Literals are compile-time computable. +2. Type conversions are compile-time computable. +3. Procedure calls of the form ``p(X)`` are compile-time computable if + ``p`` is a proc without side-effects (see the `noSideEffect pragma + <#pragmas-nosideeffect-pragma>`_ for details) and if ``X`` is a + (possibly empty) list of compile-time computable arguments. + + +Constants cannot be of type ``ptr``, ``ref`` or ``var``, nor can +they contain such a type. + + +Static statement/expression +--------------------------- + +A static statement/expression can be used to enforce compile +time evaluation explicitly. Enforced compile time evaluation can even evaluate +code that has side effects: + +.. code-block:: + + static: + echo "echo at compile time" + +It's a static error if the compiler cannot perform the evaluation at compile +time. + +The current implementation poses some restrictions for compile time +evaluation: Code which contains ``cast`` or makes use of the foreign function +interface cannot be evaluated at compile time. Later versions of Nim will +support the FFI at compile time. + + +If statement +------------ + +Example: + +.. code-block:: nim + + var name = readLine(stdin) + + if name == "Andreas": + echo "What a nice name!" + elif name == "": + echo "Don't you have a name?" + else: + echo "Boring name..." + +The ``if`` statement is a simple way to make a branch in the control flow: +The expression after the keyword ``if`` is evaluated, if it is true +the corresponding statements after the ``:`` are executed. Otherwise +the expression after the ``elif`` is evaluated (if there is an +``elif`` branch), if it is true the corresponding statements after +the ``:`` are executed. This goes on until the last ``elif``. If all +conditions fail, the ``else`` part is executed. If there is no ``else`` +part, execution continues with the next statement. + +In ``if`` statements new scopes begin immediately after the ``if``/``elif``/``else`` keywords and ends after the corresponding *then* block. +For visualization purposes the scopes have been enclosed in ``{| |}`` in the following example: + +.. code-block:: nim + if {| (let m = input =~ re"(\w+)=\w+"; m.isMatch): + echo "key ", m[0], " value ", m[1] |} + elif {| (let m = input =~ re""; m.isMatch): + echo "new m in this scope" |} + else: {| + echo "m not declared here" |} + +Case statement +-------------- + +Example: + +.. code-block:: nim + + case readline(stdin) + of "delete-everything", "restart-computer": + echo "permission denied" + of "go-for-a-walk": echo "please yourself" + else: echo "unknown command" + + # indentation of the branches is also allowed; and so is an optional colon + # after the selecting expression: + case readline(stdin): + of "delete-everything", "restart-computer": + echo "permission denied" + of "go-for-a-walk": echo "please yourself" + else: echo "unknown command" + + +The ``case`` statement is similar to the if statement, but it represents +a multi-branch selection. The expression after the keyword ``case`` is +evaluated and if its value is in a *slicelist* the corresponding statements +(after the ``of`` keyword) are executed. If the value is not in any +given *slicelist* the ``else`` part is executed. If there is no ``else`` +part and not all possible values that ``expr`` can hold occur in a +``slicelist``, a static error occurs. This holds only for expressions of +ordinal types. "All possible values" of ``expr`` are determined by ``expr``'s +type. To suppress the static error an ``else`` part with an +empty ``discard`` statement should be used. + +For non ordinal types it is not possible to list every possible value and so +these always require an ``else`` part. + +As case statements perform compile-time exhaustiveness checks, the value in +every ``of`` branch must be known at compile time. This fact is also exploited +to generate more performant code. + +As a special semantic extension, an expression in an ``of`` branch of a case +statement may evaluate to a set or array constructor; the set or array is then +expanded into a list of its elements: + +.. code-block:: nim + const + SymChars: set[char] = {'a'..'z', 'A'..'Z', '\x80'..'\xFF'} + + proc classify(s: string) = + case s[0] + of SymChars, '_': echo "an identifier" + of '0'..'9': echo "a number" + else: echo "other" + + # is equivalent to: + proc classify(s: string) = + case s[0] + of 'a'..'z', 'A'..'Z', '\x80'..'\xFF', '_': echo "an identifier" + of '0'..'9': echo "a number" + else: echo "other" + + +When statement +-------------- + +Example: + +.. code-block:: nim + + when sizeof(int) == 2: + echo "running on a 16 bit system!" + elif sizeof(int) == 4: + echo "running on a 32 bit system!" + elif sizeof(int) == 8: + echo "running on a 64 bit system!" + else: + echo "cannot happen!" + +The ``when`` statement is almost identical to the ``if`` statement with some +exceptions: + +* Each condition (``expr``) has to be a constant expression (of type ``bool``). +* The statements do not open a new scope. +* The statements that belong to the expression that evaluated to true are + translated by the compiler, the other statements are not checked for + semantics! However, each condition is checked for semantics. + +The ``when`` statement enables conditional compilation techniques. As +a special syntactic extension, the ``when`` construct is also available +within ``object`` definitions. + + +When nimvm statement +-------------------- + +``nimvm`` is a special symbol, that may be used as expression of ``when nimvm`` +statement to differentiate execution path between runtime and compile time. + +Example: + +.. code-block:: nim + proc someProcThatMayRunInCompileTime(): bool = + when nimvm: + # This code runs in compile time + result = true + else: + # This code runs in runtime + result = false + const ctValue = someProcThatMayRunInCompileTime() + let rtValue = someProcThatMayRunInCompileTime() + assert(ctValue == true) + assert(rtValue == false) + +``when nimvm`` statement must meet the following requirements: + +* Its expression must always be ``nimvm``. More complex expressions are not + allowed. +* It must not contain ``elif`` branches. +* It must contain ``else`` branch. +* Code in branches must not affect semantics of the code that follows the + ``when nimvm`` statement. E.g. it must not define symbols that are used in + the following code. + +Return statement +---------------- + +Example: + +.. code-block:: nim + return 40+2 + +The ``return`` statement ends the execution of the current procedure. +It is only allowed in procedures. If there is an ``expr``, this is syntactic +sugar for: + +.. code-block:: nim + result = expr + return result + + +``return`` without an expression is a short notation for ``return result`` if +the proc has a return type. The `result`:idx: variable is always the return +value of the procedure. It is automatically declared by the compiler. As all +variables, ``result`` is initialized to (binary) zero: + +.. code-block:: nim + proc returnZero(): int = + # implicitly returns 0 + + +Yield statement +--------------- + +Example: + +.. code-block:: nim + yield (1, 2, 3) + +The ``yield`` statement is used instead of the ``return`` statement in +iterators. It is only valid in iterators. Execution is returned to the body +of the for loop that called the iterator. Yield does not end the iteration +process, but execution is passed back to the iterator if the next iteration +starts. See the section about iterators (`Iterators and the for statement`_) +for further information. + + +Block statement +--------------- + +Example: + +.. code-block:: nim + var found = false + block myblock: + for i in 0..3: + for j in 0..3: + if a[j][i] == 7: + found = true + break myblock # leave the block, in this case both for-loops + echo found + +The block statement is a means to group statements to a (named) ``block``. +Inside the block, the ``break`` statement is allowed to leave the block +immediately. A ``break`` statement can contain a name of a surrounding +block to specify which block is to leave. + + +Break statement +--------------- + +Example: + +.. code-block:: nim + break + +The ``break`` statement is used to leave a block immediately. If ``symbol`` +is given, it is the name of the enclosing block that is to leave. If it is +absent, the innermost block is left. + + +While statement +--------------- + +Example: + +.. code-block:: nim + echo "Please tell me your password:" + var pw = readLine(stdin) + while pw != "12345": + echo "Wrong password! Next try:" + pw = readLine(stdin) + + +The ``while`` statement is executed until the ``expr`` evaluates to false. +Endless loops are no error. ``while`` statements open an `implicit block`, +so that they can be left with a ``break`` statement. + + +Continue statement +------------------ + +A ``continue`` statement leads to the immediate next iteration of the +surrounding loop construct. It is only allowed within a loop. A continue +statement is syntactic sugar for a nested block: + +.. code-block:: nim + while expr1: + stmt1 + continue + stmt2 + +Is equivalent to: + +.. code-block:: nim + while expr1: + block myBlockName: + stmt1 + break myBlockName + stmt2 + + +Assembler statement +------------------- + +The direct embedding of assembler code into Nim code is supported +by the unsafe ``asm`` statement. Identifiers in the assembler code that refer to +Nim identifiers shall be enclosed in a special character which can be +specified in the statement's pragmas. The default special character is ``'`'``: + +.. code-block:: nim + {.push stackTrace:off.} + proc addInt(a, b: int): int = + # a in eax, and b in edx + asm """ + mov eax, `a` + add eax, `b` + jno theEnd + call `raiseOverflow` + theEnd: + """ + {.pop.} + +If the GNU assembler is used, quotes and newlines are inserted automatically: + +.. code-block:: nim + proc addInt(a, b: int): int = + asm """ + addl %%ecx, %%eax + jno 1 + call `raiseOverflow` + 1: + :"=a"(`result`) + :"a"(`a`), "c"(`b`) + """ + +Instead of: + +.. code-block:: nim + proc addInt(a, b: int): int = + asm """ + "addl %%ecx, %%eax\n" + "jno 1\n" + "call `raiseOverflow`\n" + "1: \n" + :"=a"(`result`) + :"a"(`a`), "c"(`b`) + """ + +Using statement +--------------- + +The using statement provides syntactic convenience in modules where +the same parameter names and types are used over and over. Instead of: + +.. code-block:: nim + proc foo(c: Context; n: Node) = ... + proc bar(c: Context; n: Node, counter: int) = ... + proc baz(c: Context; n: Node) = ... + +One can tell the compiler about the convention that a parameter of +name ``c`` should default to type ``Context``, ``n`` should default to +``Node`` etc.: + +.. code-block:: nim + using + c: Context + n: Node + counter: int + + proc foo(c, n) = ... + proc bar(c, n, counter) = ... + proc baz(c, n) = ... + + +The ``using`` section uses the same indentation based grouping syntax as +a ``var`` or ``let`` section. + +Note that ``using`` is not applied for ``template`` since untyped template +parameters default to the type ``system.untyped``. + + +If expression +------------- + +An `if expression` is almost like an if statement, but it is an expression. +Example: + +.. code-block:: nim + var y = if x > 8: 9 else: 10 + +An if expression always results in a value, so the ``else`` part is +required. ``Elif`` parts are also allowed. + +When expression +--------------- + +Just like an `if expression`, but corresponding to the when statement. + +Case expression +--------------- + +The `case expression` is again very similar to the case statement: + +.. code-block:: nim + var favoriteFood = case animal + of "dog": "bones" + of "cat": "mice" + elif animal.endsWith"whale": "plankton" + else: + echo "I'm not sure what to serve, but everybody loves ice cream" + "ice cream" + +As seen in the above example, the case expression can also introduce side +effects. When multiple statements are given for a branch, Nim will use +the last expression as the result value, much like in an `expr` template. + +Table constructor +----------------- + +A table constructor is syntactic sugar for an array constructor: + +.. code-block:: nim + {"key1": "value1", "key2", "key3": "value2"} + + # is the same as: + [("key1", "value1"), ("key2", "value2"), ("key3", "value2")] + + +The empty table can be written ``{:}`` (in contrast to the empty set +which is ``{}``) which is thus another way to write as the empty array +constructor ``[]``. This slightly unusual way of supporting tables +has lots of advantages: + +* The order of the (key,value)-pairs is preserved, thus it is easy to + support ordered dicts with for example ``{key: val}.newOrderedTable``. +* A table literal can be put into a ``const`` section and the compiler + can easily put it into the executable's data section just like it can + for arrays and the generated data section requires a minimal amount + of memory. +* Every table implementation is treated equal syntactically. +* Apart from the minimal syntactic sugar the language core does not need to + know about tables. + + +Type conversions +---------------- +Syntactically a `type conversion` is like a procedure call, but a +type name replaces the procedure name. A type conversion is always +safe in the sense that a failure to convert a type to another +results in an exception (if it cannot be determined statically). + +Ordinary procs are often preferred over type conversions in Nim: For instance, +``$`` is the ``toString`` operator by convention and ``toFloat`` and ``toInt`` +can be used to convert from floating point to integer or vice versa. + + +Type casts +---------- +Example: + +.. code-block:: nim + cast[int](x) + +Type casts are a crude mechanism to interpret the bit pattern of +an expression as if it would be of another type. Type casts are +only needed for low-level programming and are inherently unsafe. + + +The addr operator +----------------- +The ``addr`` operator returns the address of an l-value. If the type of the +location is ``T``, the `addr` operator result is of the type ``ptr T``. An +address is always an untraced reference. Taking the address of an object that +resides on the stack is **unsafe**, as the pointer may live longer than the +object on the stack and can thus reference a non-existing object. One can get +the address of variables, but one can't use it on variables declared through +``let`` statements: + +.. code-block:: nim + + let t1 = "Hello" + var + t2 = t1 + t3 : pointer = addr(t2) + echo repr(addr(t2)) + # --> ref 0x7fff6b71b670 --> 0x10bb81050"Hello" + echo cast[ptr string](t3)[] + # --> Hello + # The following line doesn't compile: + echo repr(addr(t1)) + # Error: expression has no address + + +Procedures +========== + +What most programming languages call `methods`:idx: or `functions`:idx: are +called `procedures`:idx: in Nim. A procedure +declaration consists of an identifier, zero or more formal parameters, a return +value type and a block of code. Formal parameters are declared as a list of +identifiers separated by either comma or semicolon. A parameter is given a type +by ``: typename``. The type applies to all parameters immediately before it, +until either the beginning of the parameter list, a semicolon separator or an +already typed parameter, is reached. The semicolon can be used to make +separation of types and subsequent identifiers more distinct. + +.. code-block:: nim + # Using only commas + proc foo(a, b: int, c, d: bool): int + + # Using semicolon for visual distinction + proc foo(a, b: int; c, d: bool): int + + # Will fail: a is untyped since ';' stops type propagation. + proc foo(a; b: int; c, d: bool): int + +A parameter may be declared with a default value which is used if the caller +does not provide a value for the argument. + +.. code-block:: nim + # b is optional with 47 as its default value + proc foo(a: int, b: int = 47): int + +Parameters can be declared mutable and so allow the proc to modify those +arguments, by using the type modifier `var`. + +.. code-block:: nim + # "returning" a value to the caller through the 2nd argument + # Notice that the function uses no actual return value at all (ie void) + proc foo(inp: int, outp: var int) = + outp = inp + 47 + +If the proc declaration has no body, it is a `forward`:idx: declaration. If the +proc returns a value, the procedure body can access an implicitly declared +variable named `result`:idx: that represents the return value. Procs can be +overloaded. The overloading resolution algorithm determines which proc is the +best match for the arguments. Example: + +.. code-block:: nim + + proc toLower(c: char): char = # toLower for characters + if c in {'A'..'Z'}: + result = chr(ord(c) + (ord('a') - ord('A'))) + else: + result = c + + proc toLower(s: string): string = # toLower for strings + result = newString(len(s)) + for i in 0..len(s) - 1: + result[i] = toLower(s[i]) # calls toLower for characters; no recursion! + +Calling a procedure can be done in many different ways: + +.. code-block:: nim + proc callme(x, y: int, s: string = "", c: char, b: bool = false) = ... + + # call with positional arguments # parameter bindings: + callme(0, 1, "abc", '\t', true) # (x=0, y=1, s="abc", c='\t', b=true) + # call with named and positional arguments: + callme(y=1, x=0, "abd", '\t') # (x=0, y=1, s="abd", c='\t', b=false) + # call with named arguments (order is not relevant): + callme(c='\t', y=1, x=0) # (x=0, y=1, s="", c='\t', b=false) + # call as a command statement: no () needed: + callme 0, 1, "abc", '\t' # (x=0, y=1, s="abc", c='\t', b=false) + +A procedure may call itself recursively. + + +`Operators`:idx: are procedures with a special operator symbol as identifier: + +.. code-block:: nim + proc `$` (x: int): string = + # converts an integer to a string; this is a prefix operator. + result = intToStr(x) + +Operators with one parameter are prefix operators, operators with two +parameters are infix operators. (However, the parser distinguishes these from +the operator's position within an expression.) There is no way to declare +postfix operators: all postfix operators are built-in and handled by the +grammar explicitly. + +Any operator can be called like an ordinary proc with the '`opr`' +notation. (Thus an operator can have more than two parameters): + +.. code-block:: nim + proc `*+` (a, b, c: int): int = + # Multiply and add + result = a * b + c + + assert `*+`(3, 4, 6) == `*`(a, `+`(b, c)) + + +Export marker +------------- + +If a declared symbol is marked with an `asterisk`:idx: it is exported from the +current module: + +.. code-block:: nim + + proc exportedEcho*(s: string) = echo s + proc `*`*(a: string; b: int): string = + result = newStringOfCap(a.len * b) + for i in 1..b: result.add a + + var exportedVar*: int + const exportedConst* = 78 + type + ExportedType* = object + exportedField*: int + + +Method call syntax +------------------ + +For object oriented programming, the syntax ``obj.method(args)`` can be used +instead of ``method(obj, args)``. The parentheses can be omitted if there are no +remaining arguments: ``obj.len`` (instead of ``len(obj)``). + +This method call syntax is not restricted to objects, it can be used +to supply any type of first argument for procedures: + +.. code-block:: nim + + echo "abc".len # is the same as echo len "abc" + echo "abc".toUpper() + echo {'a', 'b', 'c'}.card + stdout.writeLine("Hallo") # the same as writeLine(stdout, "Hallo") + +Another way to look at the method call syntax is that it provides the missing +postfix notation. + +The method call syntax conflicts with explicit generic instantiations: +``p[T](x)`` cannot be written as ``x.p[T]`` because ``x.p[T]`` is always +parsed as ``(x.p)[T]``. + +See also: `Limitations of the method call syntax +<#templates-limitations-of-the-method-call-syntax>`_. + +The ``[: ]`` notation has been designed to mitigate this issue: ``x.p[:T]`` +is rewritten by the parser to ``p[T](x)``, ``x.p[:T](y)`` is rewritten to +``p[T](x, y)``. Note that ``[: ]`` has no AST representation, the rewrite +is performed directly in the parsing step. + + +Properties +---------- +Nim has no need for *get-properties*: Ordinary get-procedures that are called +with the *method call syntax* achieve the same. But setting a value is +different; for this a special setter syntax is needed: + +.. code-block:: nim + + type + Socket* = ref object of RootObj + FHost: int # cannot be accessed from the outside of the module + # the `F` prefix is a convention to avoid clashes since + # the accessors are named `host` + + proc `host=`*(s: var Socket, value: int) {.inline.} = + ## setter of hostAddr + s.FHost = value + + proc host*(s: Socket): int {.inline.} = + ## getter of hostAddr + s.FHost + + var s: Socket + new s + s.host = 34 # same as `host=`(s, 34) + + +Command invocation syntax +------------------------- + +Routines can be invoked without the ``()`` if the call is syntactically +a statement. This command invocation syntax also works for +expressions, but then only a single argument may follow. This restriction +means ``echo f 1, f 2`` is parsed as ``echo(f(1), f(2))`` and not as +``echo(f(1, f(2)))``. The method call syntax may be used to provide one +more argument in this case: + +.. code-block:: nim + proc optarg(x: int, y: int = 0): int = x + y + proc singlearg(x: int): int = 20*x + + echo optarg 1, " ", singlearg 2 # prints "1 40" + + let fail = optarg 1, optarg 8 # Wrong. Too many arguments for a command call + let x = optarg(1, optarg 8) # traditional procedure call with 2 arguments + let y = 1.optarg optarg 8 # same thing as above, w/o the parenthesis + assert x == y + +The command invocation syntax also can't have complex expressions as arguments. +For example: (`anonymous procs`_), ``if``, ``case`` or ``try``. The (`do +notation`_) is limited, but usable for a single proc (see the example in the +corresponding section). Function calls with no arguments still needs () to +distinguish between a call and the function itself as a first class value. + + +Closures +-------- + +Procedures can appear at the top level in a module as well as inside other +scopes, in which case they are called nested procs. A nested proc can access +local variables from its enclosing scope and if it does so it becomes a +closure. Any captured variables are stored in a hidden additional argument +to the closure (its environment) and they are accessed by reference by both +the closure and its enclosing scope (i.e. any modifications made to them are +visible in both places). The closure environment may be allocated on the heap +or on the stack if the compiler determines that this would be safe. + +Creating closures in loops +~~~~~~~~~~~~~~~~ + +Since closures capture local variables by reference it is often not wanted +behavior inside loop bodies. See `closureScope `_ +for details on how to change this behavior. + +Anonymous Procs +--------------- + +Procs can also be treated as expressions, in which case it's allowed to omit +the proc's name. + +.. code-block:: nim + var cities = @["Frankfurt", "Tokyo", "New York", "Kyiv"] + + cities.sort(proc (x,y: string): int = + cmp(x.len, y.len)) + + +Procs as expressions can appear both as nested procs and inside top level +executable code. + + +Do notation +----------- + +As a special more convenient notation, proc expressions involved in procedure +calls can use the ``do`` keyword: + +.. code-block:: nim + sort(cities) do (x,y: string) -> int: + cmp(x.len, y.len) + + # Less parenthesis using the method plus command syntax: + cities = cities.map do (x:string) -> string: + "City of " & x + + # In macros, the do notation is often used for quasi-quoting + macroResults.add quote do: + if not `ex`: + echo `info`, ": Check failed: ", `expString` + +``do`` is written after the parentheses enclosing the regular proc params. +The proc expression represented by the do block is appended to them. +In calls using the command syntax, the do block will bind to the immediately +preceeding expression, transforming it in a call. + +``do`` with parentheses is an anonymous ``proc``; however a ``do`` without +parentheses is just a block of code. The ``do`` notation can be used to +pass multiple blocks to a macro: + +.. code-block:: nim + macro performWithUndo(task, undo: untyped) = ... + + performWithUndo do: + # multiple-line block of code + # to perform the task + do: + # code to undo it + + +Nonoverloadable builtins +------------------------ + +The following builtin procs cannot be overloaded for reasons of implementation +simplicity (they require specialized semantic checking):: + + declared, defined, definedInScope, compiles, sizeOf, + is, shallowCopy, getAst, astToStr, spawn, procCall + +Thus they act more like keywords than like ordinary identifiers; unlike a +keyword however, a redefinition may `shadow`:idx: the definition in +the ``system`` module. From this list the following should not be written in dot +notation ``x.f`` since ``x`` cannot be type checked before it gets passed +to ``f``:: + + declared, defined, definedInScope, compiles, getAst, astToStr + + +Var parameters +-------------- +The type of a parameter may be prefixed with the ``var`` keyword: + +.. code-block:: nim + proc divmod(a, b: int; res, remainder: var int) = + res = a div b + remainder = a mod b + + var + x, y: int + + divmod(8, 5, x, y) # modifies x and y + assert x == 1 + assert y == 3 + +In the example, ``res`` and ``remainder`` are `var parameters`. +Var parameters can be modified by the procedure and the changes are +visible to the caller. The argument passed to a var parameter has to be +an l-value. Var parameters are implemented as hidden pointers. The +above example is equivalent to: + +.. code-block:: nim + proc divmod(a, b: int; res, remainder: ptr int) = + res[] = a div b + remainder[] = a mod b + + var + x, y: int + divmod(8, 5, addr(x), addr(y)) + assert x == 1 + assert y == 3 + +In the examples, var parameters or pointers are used to provide two +return values. This can be done in a cleaner way by returning a tuple: + +.. code-block:: nim + proc divmod(a, b: int): tuple[res, remainder: int] = + (a div b, a mod b) + + var t = divmod(8, 5) + + assert t.res == 1 + assert t.remainder == 3 + +One can use `tuple unpacking`:idx: to access the tuple's fields: + +.. code-block:: nim + var (x, y) = divmod(8, 5) # tuple unpacking + assert x == 1 + assert y == 3 + + +**Note**: ``var`` parameters are never necessary for efficient parameter +passing. Since non-var parameters cannot be modified the compiler is always +free to pass arguments by reference if it considers it can speed up execution. + + +Var return type +--------------- + +A proc, converter or iterator may return a ``var`` type which means that the +returned value is an l-value and can be modified by the caller: + +.. code-block:: nim + var g = 0 + + proc WriteAccessToG(): var int = + result = g + + WriteAccessToG() = 6 + assert g == 6 + +It is a compile time error if the implicitly introduced pointer could be +used to access a location beyond its lifetime: + +.. code-block:: nim + proc WriteAccessToG(): var int = + var g = 0 + result = g # Error! + +For iterators, a component of a tuple return type can have a ``var`` type too: + +.. code-block:: nim + iterator mpairs(a: var seq[string]): tuple[key: int, val: var string] = + for i in 0..a.high: + yield (i, a[i]) + +In the standard library every name of a routine that returns a ``var`` type +starts with the prefix ``m`` per convention. + + +Overloading of the subscript operator +------------------------------------- + +The ``[]`` subscript operator for arrays/openarrays/sequences can be overloaded. + + +Multi-methods +============= + +Procedures always use static dispatch. Multi-methods use dynamic +dispatch. For dynamic dispatch to work on an object it should be a reference +type as well. + +.. code-block:: nim + type + Expression = ref object of RootObj ## abstract base class for an expression + Literal = ref object of Expression + x: int + PlusExpr = ref object of Expression + a, b: Expression + + method eval(e: Expression): int {.base.} = + # override this base method + quit "to override!" + + method eval(e: Literal): int = return e.x + + method eval(e: PlusExpr): int = + # watch out: relies on dynamic binding + result = eval(e.a) + eval(e.b) + + proc newLit(x: int): Literal = + new(result) + result.x = x + + proc newPlus(a, b: Expression): PlusExpr = + new(result) + result.a = a + result.b = b + + echo eval(newPlus(newPlus(newLit(1), newLit(2)), newLit(4))) + +In the example the constructors ``newLit`` and ``newPlus`` are procs +because they should use static binding, but ``eval`` is a method because it +requires dynamic binding. + +As can be seen in the example, base methods have to be annotated with +the `base`:idx: pragma. The ``base`` pragma also acts as a reminder for the +programmer that a base method ``m`` is used as the foundation to determine all +the effects that a call to ``m`` might cause. + +In a multi-method all parameters that have an object type are used for the +dispatching: + +.. code-block:: nim + type + Thing = ref object of RootObj + Unit = ref object of Thing + x: int + + method collide(a, b: Thing) {.base, inline.} = + quit "to override!" + + method collide(a: Thing, b: Unit) {.inline.} = + echo "1" + + method collide(a: Unit, b: Thing) {.inline.} = + echo "2" + + var a, b: Unit + new a + new b + collide(a, b) # output: 2 + + +Invocation of a multi-method cannot be ambiguous: collide 2 is preferred over +collide 1 because the resolution works from left to right. +In the example ``Unit, Thing`` is preferred over ``Thing, Unit``. + +**Performance note**: Nim does not produce a virtual method table, but +generates dispatch trees. This avoids the expensive indirect branch for method +calls and enables inlining. However, other optimizations like compile time +evaluation or dead code elimination do not work with methods. + + +Iterators and the for statement +=============================== + +The `for`:idx: statement is an abstract mechanism to iterate over the elements +of a container. It relies on an `iterator`:idx: to do so. Like ``while`` +statements, ``for`` statements open an `implicit block`:idx:, so that they +can be left with a ``break`` statement. + +The ``for`` loop declares iteration variables - their scope reaches until the +end of the loop body. The iteration variables' types are inferred by the +return type of the iterator. + +An iterator is similar to a procedure, except that it can be called in the +context of a ``for`` loop. Iterators provide a way to specify the iteration over +an abstract type. A key role in the execution of a ``for`` loop plays the +``yield`` statement in the called iterator. Whenever a ``yield`` statement is +reached the data is bound to the ``for`` loop variables and control continues +in the body of the ``for`` loop. The iterator's local variables and execution +state are automatically saved between calls. Example: + +.. code-block:: nim + # this definition exists in the system module + iterator items*(a: string): char {.inline.} = + var i = 0 + while i < len(a): + yield a[i] + inc(i) + + for ch in items("hello world"): # `ch` is an iteration variable + echo ch + +The compiler generates code as if the programmer would have written this: + +.. code-block:: nim + var i = 0 + while i < len(a): + var ch = a[i] + echo ch + inc(i) + +If the iterator yields a tuple, there can be as many iteration variables +as there are components in the tuple. The i'th iteration variable's type is +the type of the i'th component. In other words, implicit tuple unpacking in a +for loop context is supported. + +Implict items/pairs invocations +------------------------------- + +If the for loop expression ``e`` does not denote an iterator and the for loop +has exactly 1 variable, the for loop expression is rewritten to ``items(e)``; +ie. an ``items`` iterator is implicitly invoked: + +.. code-block:: nim + for x in [1,2,3]: echo x + +If the for loop has exactly 2 variables, a ``pairs`` iterator is implicitly +invoked. + +Symbol lookup of the identifiers ``items``/``pairs`` is performed after +the rewriting step, so that all overloads of ``items``/``pairs`` are taken +into account. + + +First class iterators +--------------------- + +There are 2 kinds of iterators in Nim: *inline* and *closure* iterators. +An `inline iterator`:idx: is an iterator that's always inlined by the compiler +leading to zero overhead for the abstraction, but may result in a heavy +increase in code size. Inline iterators are second class citizens; +They can be passed as parameters only to other inlining code facilities like +templates, macros and other inline iterators. + +In contrast to that, a `closure iterator`:idx: can be passed around more freely: + +.. code-block:: nim + iterator count0(): int {.closure.} = + yield 0 + + iterator count2(): int {.closure.} = + var x = 1 + yield x + inc x + yield x + + proc invoke(iter: iterator(): int {.closure.}) = + for x in iter(): echo x + + invoke(count0) + invoke(count2) + +Closure iterators have other restrictions than inline iterators: + +1. ``yield`` in a closure iterator can not occur in a ``try`` statement. +2. For now, a closure iterator cannot be evaluated at compile time. +3. ``return`` is allowed in a closure iterator (but rarely useful) and ends + iteration. +4. Neither inline nor closure iterators can be recursive. +5. Closure iterators are not supported by the js backend. + +Iterators that are neither marked ``{.closure.}`` nor ``{.inline.}`` explicitly +default to being inline, but this may change in future versions of the +implementation. + +The ``iterator`` type is always of the calling convention ``closure`` +implicitly; the following example shows how to use iterators to implement +a `collaborative tasking`:idx: system: + +.. code-block:: nim + # simple tasking: + type + Task = iterator (ticker: int) + + iterator a1(ticker: int) {.closure.} = + echo "a1: A" + yield + echo "a1: B" + yield + echo "a1: C" + yield + echo "a1: D" + + iterator a2(ticker: int) {.closure.} = + echo "a2: A" + yield + echo "a2: B" + yield + echo "a2: C" + + proc runTasks(t: varargs[Task]) = + var ticker = 0 + while true: + let x = t[ticker mod t.len] + if finished(x): break + x(ticker) + inc ticker + + runTasks(a1, a2) + +The builtin ``system.finished`` can be used to determine if an iterator has +finished its operation; no exception is raised on an attempt to invoke an +iterator that has already finished its work. + +Note that ``system.finished`` is error prone to use because it only returns +``true`` one iteration after the iterator has finished: + +.. code-block:: nim + iterator mycount(a, b: int): int {.closure.} = + var x = a + while x <= b: + yield x + inc x + + var c = mycount # instantiate the iterator + while not finished(c): + echo c(1, 3) + + # Produces + 1 + 2 + 3 + 0 + +Instead this code has to be used: + +.. code-block:: nim + var c = mycount # instantiate the iterator + while true: + let value = c(1, 3) + if finished(c): break # and discard 'value'! + echo value + +It helps to think that the iterator actually returns a +pair ``(value, done)`` and ``finished`` is used to access the hidden ``done`` +field. + + +Closure iterators are *resumable functions* and so one has to provide the +arguments to every call. To get around this limitation one can capture +parameters of an outer factory proc: + +.. code-block:: nim + proc mycount(a, b: int): iterator (): int = + result = iterator (): int = + var x = a + while x <= b: + yield x + inc x + + let foo = mycount(1, 4) + + for f in foo(): + echo f + +.. + Implicit return type + -------------------- + + Since inline iterators must always produce values that will be consumed in + a for loop, the compiler will implicitly use the ``auto`` return type if no + type is given by the user. In contrast, since closure iterators can be used + as a collaborative tasking system, ``void`` is a valid return type for them. + + +Converters +========== + +A converter is like an ordinary proc except that it enhances +the "implicitly convertible" type relation (see `Convertible relation`_): + +.. code-block:: nim + # bad style ahead: Nim is not C. + converter toBool(x: int): bool = x != 0 + + if 4: + echo "compiles" + + +A converter can also be explicitly invoked for improved readability. Note that +implicit converter chaining is not supported: If there is a converter from +type A to type B and from type B to type C the implicit conversion from A to C +is not provided. + + +Type sections +============= + +Example: + +.. code-block:: nim + type # example demonstrating mutually recursive types + Node = ref object # an object managed by the garbage collector (ref) + le, ri: Node # left and right subtrees + sym: ref Sym # leaves contain a reference to a Sym + + Sym = object # a symbol + name: string # the symbol's name + line: int # the line the symbol was declared in + code: Node # the symbol's abstract syntax tree + +A type section begins with the ``type`` keyword. It contains multiple +type definitions. A type definition binds a type to a name. Type definitions +can be recursive or even mutually recursive. Mutually recursive types are only +possible within a single ``type`` section. Nominal types like ``objects`` +or ``enums`` can only be defined in a ``type`` section. + + + +Exception handling +================== + +Try statement +------------- + +Example: + +.. code-block:: nim + # read the first two lines of a text file that should contain numbers + # and tries to add them + var + f: File + if open(f, "numbers.txt"): + try: + var a = readLine(f) + var b = readLine(f) + echo "sum: " & $(parseInt(a) + parseInt(b)) + except OverflowError: + echo "overflow!" + except ValueError: + echo "could not convert string to integer" + except IOError: + echo "IO error!" + except: + echo "Unknown exception!" + finally: + close(f) + + +The statements after the ``try`` are executed in sequential order unless +an exception ``e`` is raised. If the exception type of ``e`` matches any +listed in an ``except`` clause the corresponding statements are executed. +The statements following the ``except`` clauses are called +`exception handlers`:idx:. + +The empty `except`:idx: clause is executed if there is an exception that is +not listed otherwise. It is similar to an ``else`` clause in ``if`` statements. + +If there is a `finally`:idx: clause, it is always executed after the +exception handlers. + +The exception is *consumed* in an exception handler. However, an +exception handler may raise another exception. If the exception is not +handled, it is propagated through the call stack. This means that often +the rest of the procedure - that is not within a ``finally`` clause - +is not executed (if an exception occurs). + + +Try expression +-------------- + +Try can also be used as an expression; the type of the ``try`` branch then +needs to fit the types of ``except`` branches, but the type of the ``finally`` +branch always has to be ``void``: + +.. code-block:: nim + let x = try: parseInt("133a") + except: -1 + finally: echo "hi" + + +To prevent confusing code there is a parsing limitation; if the ``try`` +follows a ``(`` it has to be written as a one liner: + +.. code-block:: nim + let x = (try: parseInt("133a") except: -1) + + +Except clauses +-------------- + +Within an ``except`` clause, it is possible to use +``getCurrentException`` to retrieve the exception that has been +raised: + +.. code-block:: nim + try: + # ... + except IOError: + let e = getCurrentException() + # Now use "e" + +Note that ``getCurrentException`` always returns a ``ref Exception`` +type. If a variable of the proper type is needed (in the example +above, ``IOError``), one must convert it explicitly: + +.. code-block:: nim + try: + # ... + except IOError: + let e = (ref IOError)(getCurrentException()) + # "e" is now of the proper type + +However, this is seldom needed. The most common case is to extract an +error message from ``e``, and for such situations it is enough to use +``getCurrentExceptionMsg``: + +.. code-block:: nim + try: + # ... + except IOError: + echo "I/O error: " & getCurrentExceptionMsg() + + +Defer statement +--------------- + +Instead of a ``try finally`` statement a ``defer`` statement can be used. + +Any statements following the ``defer`` in the current block will be considered +to be in an implicit try block: + +.. code-block:: nim + var f = open("numbers.txt") + defer: close(f) + f.write "abc" + f.write "def" + +Is rewritten to: + +.. code-block:: nim + var f = open("numbers.txt") + try: + f.write "abc" + f.write "def" + finally: + close(f) + +Top level ``defer`` statements are not supported +since it's unclear what such a statement should refer to. + + +Raise statement +--------------- + +Example: + +.. code-block:: nim + raise newEOS("operating system failed") + +Apart from built-in operations like array indexing, memory allocation, etc. +the ``raise`` statement is the only way to raise an exception. + +.. XXX document this better! + +If no exception name is given, the current exception is `re-raised`:idx:. The +`ReraiseError`:idx: exception is raised if there is no exception to +re-raise. It follows that the ``raise`` statement *always* raises an +exception. + + +Exception hierarchy +------------------- + +The exception tree is defined in the `system `_ module: + +.. include:: exception_hierarchy_fragment.txt + + +Imported exceptions +------------------- + +It is possible to raise/catch imported C++ exceptions. Types imported using +`importcpp` can be raised or caught. Exceptions are raised by value and +caught by reference. Example: + +.. code-block:: nim + + type + std_exception {.importcpp: "std::exception", header: "".} = object + + proc what(s: std_exception): cstring {.importcpp: "((char *)#.what())".} + + try: + raise std_exception() + except std_exception as ex: + echo ex.what() + + + +Effect system +============= + +Exception tracking +------------------ + +Nim supports exception tracking. The `raises`:idx: pragma can be used +to explicitly define which exceptions a proc/iterator/method/converter is +allowed to raise. The compiler verifies this: + +.. code-block:: nim + proc p(what: bool) {.raises: [IOError, OSError].} = + if what: raise newException(IOError, "IO") + else: raise newException(OSError, "OS") + +An empty ``raises`` list (``raises: []``) means that no exception may be raised: + +.. code-block:: nim + proc p(): bool {.raises: [].} = + try: + unsafeCall() + result = true + except: + result = false + + +A ``raises`` list can also be attached to a proc type. This affects type +compatibility: + +.. code-block:: nim + type + Callback = proc (s: string) {.raises: [IOError].} + var + c: Callback + + proc p(x: string) = + raise newException(OSError, "OS") + + c = p # type error + + +For a routine ``p`` the compiler uses inference rules to determine the set of +possibly raised exceptions; the algorithm operates on ``p``'s call graph: + +1. Every indirect call via some proc type ``T`` is assumed to + raise ``system.Exception`` (the base type of the exception hierarchy) and + thus any exception unless ``T`` has an explicit ``raises`` list. + However if the call is of the form ``f(...)`` where ``f`` is a parameter + of the currently analysed routine it is ignored. The call is optimistically + assumed to have no effect. Rule 2 compensates for this case. +2. Every expression of some proc type within a call that is not a call + itself (and not nil) is assumed to be called indirectly somehow and thus + its raises list is added to ``p``'s raises list. +3. Every call to a proc ``q`` which has an unknown body (due to a forward + declaration or an ``importc`` pragma) is assumed to + raise ``system.Exception`` unless ``q`` has an explicit ``raises`` list. +4. Every call to a method ``m`` is assumed to + raise ``system.Exception`` unless ``m`` has an explicit ``raises`` list. +5. For every other call the analysis can determine an exact ``raises`` list. +6. For determining a ``raises`` list, the ``raise`` and ``try`` statements + of ``p`` are taken into consideration. + +Rules 1-2 ensure the following works: + +.. code-block:: nim + proc noRaise(x: proc()) {.raises: [].} = + # unknown call that might raise anything, but valid: + x() + + proc doRaise() {.raises: [IOError].} = + raise newException(IOError, "IO") + + proc use() {.raises: [].} = + # doesn't compile! Can raise IOError! + noRaise(doRaise) + +So in many cases a callback does not cause the compiler to be overly +conservative in its effect analysis. + + +Tag tracking +------------ + +The exception tracking is part of Nim's `effect system`:idx:. Raising an +exception is an *effect*. Other effects can also be defined. A user defined +effect is a means to *tag* a routine and to perform checks against this tag: + +.. code-block:: nim + type IO = object ## input/output effect + proc readLine(): string {.tags: [IO].} + + proc no_IO_please() {.tags: [].} = + # the compiler prevents this: + let x = readLine() + +A tag has to be a type name. A ``tags`` list - like a ``raises`` list - can +also be attached to a proc type. This affects type compatibility. + +The inference for tag tracking is analogous to the inference for +exception tracking. + + +Read/Write tracking +------------------- + +**Note**: Read/write tracking is not yet implemented! + +The inference for read/write tracking is analogous to the inference for +exception tracking. + + +Effects pragma +-------------- + +The ``effects`` pragma has been designed to assist the programmer with the +effects analysis. It is a statement that makes the compiler output all inferred +effects up to the ``effects``'s position: + +.. code-block:: nim + proc p(what: bool) = + if what: + raise newException(IOError, "IO") + {.effects.} + else: + raise newException(OSError, "OS") + +The compiler produces a hint message that ``IOError`` can be raised. ``OSError`` +is not listed as it cannot be raised in the branch the ``effects`` pragma +appears in. + + +Generics +======== + +Generics are Nim's means to parametrize procs, iterators or types with +`type parameters`:idx:. Depending on context, the brackets are used either to +introduce type parameters or to instantiate a generic proc, iterator or type. + +The following example shows a generic binary tree can be modelled: + +.. code-block:: nim + type + BinaryTree*[T] = ref object # BinaryTree is a generic type with + # generic param ``T`` + le, ri: BinaryTree[T] # left and right subtrees; may be nil + data: T # the data stored in a node + + proc newNode*[T](data: T): BinaryTree[T] = + # constructor for a node + new(result) + result.data = data + + proc add*[T](root: var BinaryTree[T], n: BinaryTree[T]) = + # insert a node into the tree + if root == nil: + root = n + else: + var it = root + while it != nil: + # compare the data items; uses the generic ``cmp`` proc + # that works for any type that has a ``==`` and ``<`` operator + var c = cmp(it.data, n.data) + if c < 0: + if it.le == nil: + it.le = n + return + it = it.le + else: + if it.ri == nil: + it.ri = n + return + it = it.ri + + proc add*[T](root: var BinaryTree[T], data: T) = + # convenience proc: + add(root, newNode(data)) + + iterator preorder*[T](root: BinaryTree[T]): T = + # Preorder traversal of a binary tree. + # Since recursive iterators are not yet implemented, + # this uses an explicit stack (which is more efficient anyway): + var stack: seq[BinaryTree[T]] = @[root] + while stack.len > 0: + var n = stack.pop() + while n != nil: + yield n.data + add(stack, n.ri) # push right subtree onto the stack + n = n.le # and follow the left pointer + + var + root: BinaryTree[string] # instantiate a BinaryTree with ``string`` + add(root, newNode("hello")) # instantiates ``newNode`` and ``add`` + add(root, "world") # instantiates the second ``add`` proc + for str in preorder(root): + stdout.writeLine(str) + +The ``T`` is called a `generic type parameter`:idx:. + + +Is operator +----------- + +The ``is`` operator checks for type equivalence at compile time. It is +therefore very useful for type specialization within generic code: + +.. code-block:: nim + type + Table[Key, Value] = object + keys: seq[Key] + values: seq[Value] + when not (Key is string): # nil value for strings used for optimization + deletedKeys: seq[bool] + + +Type operator +------------- + +The ``type`` (in many other languages called `typeof`:idx:) operator can +be used to get the type of an expression: + +.. code-block:: nim + var x = 0 + var y: type(x) # y has type int + +If ``type`` is used to determine the result type of a proc/iterator/converter +call ``c(X)`` (where ``X`` stands for a possibly empty list of arguments), the +interpretation where ``c`` is an iterator is preferred over the +other interpretations: + +.. code-block:: nim + import strutils + + # strutils contains both a ``split`` proc and iterator, but since an + # an iterator is the preferred interpretation, `y` has the type ``string``: + var y: type("a b c".split) + + +Type Classes +------------ + +A type class is a special pseudo-type that can be used to match against +types in the context of overload resolution or the ``is`` operator. +Nim supports the following built-in type classes: + +================== =================================================== +type class matches +================== =================================================== +``object`` any object type +``tuple`` any tuple type + +``enum`` any enumeration +``proc`` any proc type +``ref`` any ``ref`` type +``ptr`` any ``ptr`` type +``var`` any ``var`` type +``distinct`` any distinct type +``array`` any array type +``set`` any set type +``seq`` any seq type +``auto`` any type +``any`` distinct auto (see below) +================== =================================================== + +Furthermore, every generic type automatically creates a type class of the same +name that will match any instantiation of the generic type. + +Type classes can be combined using the standard boolean operators to form +more complex type classes: + +.. code-block:: nim + # create a type class that will match all tuple and object types + type RecordType = tuple or object + + proc printFields(rec: RecordType) = + for key, value in fieldPairs(rec): + echo key, " = ", value + +Procedures utilizing type classes in such manner are considered to be +`implicitly generic`:idx:. They will be instantiated once for each unique +combination of param types used within the program. + +Nim also allows for type classes and regular types to be specified +as `type constraints`:idx: of the generic type parameter: + +.. code-block:: nim + proc onlyIntOrString[T: int|string](x, y: T) = discard + + onlyIntOrString(450, 616) # valid + onlyIntOrString(5.0, 0.0) # type mismatch + onlyIntOrString("xy", 50) # invalid as 'T' cannot be both at the same time + +By default, during overload resolution each named type class will bind to +exactly one concrete type. We call such type classes `bind once`:idx: types. +Here is an example taken directly from the system module to illustrate this: + +.. code-block:: nim + proc `==`*(x, y: tuple): bool = + ## requires `x` and `y` to be of the same tuple type + ## generic ``==`` operator for tuples that is lifted from the components + ## of `x` and `y`. + result = true + for a, b in fields(x, y): + if a != b: result = false + +Alternatively, the ``distinct`` type modifier can be applied to the type class +to allow each param matching the type class to bind to a different type. Such +type classes are called `bind many`:idx: types. + +Procs written with the implicitly generic style will often need to refer to the +type parameters of the matched generic type. They can be easily accessed using +the dot syntax: + +.. code-block:: nim + type Matrix[T, Rows, Columns] = object + ... + + proc `[]`(m: Matrix, row, col: int): Matrix.T = + m.data[col * high(Matrix.Columns) + row] + +Alternatively, the `type` operator can be used over the proc params for similar +effect when anonymous or distinct type classes are used. + +When a generic type is instantiated with a type class instead of a concrete +type, this results in another more specific type class: + +.. code-block:: nim + seq[ref object] # Any sequence storing references to any object type + + type T1 = auto + proc foo(s: seq[T1], e: T1) + # seq[T1] is the same as just `seq`, but T1 will be allowed to bind + # to a single type, while the signature is being matched + + Matrix[Ordinal] # Any Matrix instantiation using integer values + +As seen in the previous example, in such instantiations, it's not necessary to +supply all type parameters of the generic type, because any missing ones will +be inferred to have the equivalent of the `any` type class and thus they will +match anything without discrimination. + + +Concepts +-------- + +**Note**: Concepts are still in development. + +Concepts, also known as "user-defined type classes", are used to specify an +arbitrary set of requirements that the matched type must satisfy. + +Concepts are written in the following form: + +.. code-block:: nim + type + Comparable = concept x, y + (x < y) is bool + + Stack[T] = concept s, var v + s.pop() is T + v.push(T) + + s.len is Ordinal + + for value in s: + value is T + +The concept is a match if: + +a) all of the expressions within the body can be compiled for the tested type +b) all statically evaluable boolean expressions in the body must be true + +The identifiers following the ``concept`` keyword represent instances of the +currently matched type. You can apply any of the standard type modifiers such +as ``var``, ``ref``, ``ptr`` and ``static`` to denote a more specific type of +instance. You can also apply the `type` modifier to create a named instance of +the type itself: + +.. code-block:: nim + type + MyConcept = concept x, var v, ref r, ptr p, static s, type T + ... + +Within the concept body, types can appear in positions where ordinary values +and parameters are expected. This provides a more convenient way to check for +the presence of callable symbols with specific signatures: + +.. code-block:: nim + type + OutputStream = concept var s + s.write(string) + +In order to check for symbols accepting ``typedesc`` params, you must prefix +the type with an explicit ``type`` modifier. The named instance of the type, +following the ``concept`` keyword is also considered an explicit ``typedesc`` +value that will be matched only as a type. + +.. code-block:: nim + type + # Let's imagine a user-defined casting framework with operators + # such as `val.to(string)` and `val.to(JSonValue)`. We can test + # for these with the following concept: + MyCastables = concept x + x.to(type string) + x.to(type JSonValue) + + # Let's define a couple of concepts, known from Algebra: + AdditiveMonoid* = concept x, y, type T + x + y is T + T.zero is T # require a proc such as `int.zero` or 'Position.zero' + + AdditiveGroup* = concept x, y, type T + x is AdditiveMonoid + -x is T + x - y is T + +Please note that the ``is`` operator allows one to easily verify the precise +type signatures of the required operations, but since type inference and +default parameters are still applied in the concept body, it's also possible +to describe usage protocols that do not reveal implementation details. + +Much like generics, concepts are instantiated exactly once for each tested type +and any static code included within the body is executed only once. + + +Concept diagnostics +------------------- + +By default, the compiler will report the matching errors in concepts only when +no other overload can be selected and a normal compilation error is produced. +When you need to understand why the compiler is not matching a particular +concept and, as a result, a wrong overload is selected, you can apply the +``explain`` pragma to either the concept body or a particular call-site. + +.. code-block:: nim + type + MyConcept {.explain.} = concept ... + + overloadedProc(x, y, z) {.explain.} + +This will provide Hints in the compiler output either every time the concept is +not matched or only on the particular call-site. + + +Generic concepts and type binding rules +--------------------------------------- + +The concept types can be parametric just like the regular generic types: + +.. code-block:: nim + ### matrixalgo.nim + + import typetraits + + type + AnyMatrix*[R, C: static[int]; T] = concept m, var mvar, type M + M.ValueType is T + M.Rows == R + M.Cols == C + + m[int, int] is T + mvar[int, int] = T + + type TransposedType = stripGenericParams(M)[C, R, T] + + AnySquareMatrix*[N: static[int], T] = AnyMatrix[N, N, T] + + AnyTransform3D* = AnyMatrix[4, 4, float] + + proc transposed*(m: AnyMatrix): m.TransposedType = + for r in 0 ..< m.R: + for c in 0 ..< m.C: + result[r, c] = m[c, r] + + proc determinant*(m: AnySquareMatrix): int = + ... + + proc setPerspectiveProjection*(m: AnyTransform3D) = + ... + + -------------- + ### matrix.nim + + type + Matrix*[M, N: static[int]; T] = object + data: array[M*N, T] + + proc `[]`*(M: Matrix; m, n: int): M.T = + M.data[m * M.N + n] + + proc `[]=`*(M: var Matrix; m, n: int; v: M.T) = + M.data[m * M.N + n] = v + + # Adapt the Matrix type to the concept's requirements + template Rows*(M: type Matrix): expr = M.M + template Cols*(M: type Matrix): expr = M.N + template ValueType*(M: type Matrix): typedesc = M.T + + ------------- + ### usage.nim + + import matrix, matrixalgo + + var + m: Matrix[3, 3, int] + projectionMatrix: Matrix[4, 4, float] + + echo m.transposed.determinant + setPerspectiveProjection projectionMatrix + +When the concept type is matched against a concrete type, the unbound type +parameters are inferred from the body of the concept in a way that closely +resembles the way generic parameters of callable symbols are inferred on +call sites. + +Unbound types can appear both as params to calls such as `s.push(T)` and +on the right-hand side of the ``is`` operator in cases such as `x.pop is T` +and `x.data is seq[T]`. + +Unbound static params will be inferred from expressions involving the `==` +operator and also when types dependent on them are being matched: + +.. code-block:: nim + type + MatrixReducer[M, N: static[int]; T] = concept x + x.reduce(SquareMatrix[N, T]) is array[M, int] + +The Nim compiler includes a simple linear equation solver, allowing it to +infer static params in some situations where integer arithmetic is involved. + +Just like in regular type classes, Nim discriminates between ``bind once`` +and ``bind many`` types when matching the concept. You can add the ``distinct`` +modifier to any of the otherwise inferable types to get a type that will be +matched without permanently inferring it. This may be useful when you need +to match several procs accepting the same wide class of types: + +.. code-block:: nim + type + Enumerable[T] = concept e + for v in e: + v is T + + type + MyConcept = concept o + # this could be inferred to a type such as Enumerable[int] + o.foo is distinct Enumerable + + # this could be inferred to a different type such as Enumerable[float] + o.bar is distinct Enumerable + + # it's also possible to give an alias name to a `bind many` type class + type Enum = distinct Enumerable + o.baz is Enum + +On the other hand, using ``bind once`` types allows you to test for equivalent +types used in multiple signatures, without actually requiring any concrete +types, thus allowing you to encode implementation-defined types: + +.. code-block:: nim + type + MyConcept = concept x + type T1 = auto + x.foo(T1) + x.bar(T1) # both procs must accept the same type + + type T2 = seq[SomeNumber] + x.alpha(T2) + x.omega(T2) # both procs must accept the same type + # and it must be a numeric sequence + +As seen in the previous examples, you can refer to generic concepts such as +`Enumerable[T]` just by their short name. Much like the regular generic types, +the concept will be automatically instantiated with the bind once auto type +in the place of each missing generic param. + +Please note that generic concepts such as `Enumerable[T]` can be matched +against concrete types such as `string`. Nim doesn't require the concept +type to have the same number of parameters as the type being matched. +If you wish to express a requirement towards the generic parameters of +the matched type, you can use a type mapping operator such as `genericHead` +or `stripGenericParams` within the body of the concept to obtain the +uninstantiated version of the type, which you can then try to instantiate +in any required way. For example, here is how one might define the classic +`Functor` concept from Haskell and then demonstrate that Nim's `Option[T]` +type is an instance of it: + +.. code-block:: nim + import future, typetraits + + type + Functor[A] = concept f + type MatchedGenericType = genericHead(f.type) + # `f` will be a value of a type such as `Option[T]` + # `MatchedGenericType` will become the `Option` type + + f.val is A + # The Functor should provide a way to obtain + # a value stored inside it + + type T = auto + map(f, A -> T) is MatchedGenericType[T] + # And it should provide a way to map one instance of + # the Functor to a instance of a different type, given + # a suitable `map` operation for the enclosed values + + import options + echo Option[int] is Functor # prints true + + +Concept derived values +---------------------- + +All top level constants or types appearing within the concept body are +accessible through the dot operator in procs where the concept was successfully +matched to a concrete type: + +.. code-block:: nim + type + DateTime = concept t1, t2, type T + const Min = T.MinDate + T.Now is T + + t1 < t2 is bool + + type TimeSpan = type(t1 - t2) + TimeSpan * int is TimeSpan + TimeSpan + TimeSpan is TimeSpan + + t1 + TimeSpan is T + + proc eventsJitter(events: Enumerable[DateTime]): float = + var + # this variable will have the inferred TimeSpan type for + # the concrete Date-like value the proc was called with: + averageInterval: DateTime.TimeSpan + + deviation: float + ... + + +Concept refinement +------------------ + +When the matched type within a concept is directly tested against a different +concept, we say that the outer concept is a refinement of the inner concept and +thus it is more-specific. When both concepts are matched in a call during +overload resolution, Nim will assign a higher precedence to the most specific +one. As an alternative way of defining concept refinements, you can use the +object inheritance syntax involving the ``of`` keyword: + +.. code-block:: nim + type + Graph = concept g, type G of EqualyComparable, Copyable + type + VertexType = G.VertexType + EdgeType = G.EdgeType + + VertexType is Copyable + EdgeType is Copyable + + var + v: VertexType + e: EdgeType + + IncidendeGraph = concept of Graph + # symbols such as variables and types from the refined + # concept are automatically in scope: + + g.source(e) is VertexType + g.target(e) is VertexType + + g.outgoingEdges(v) is Enumerable[EdgeType] + + BidirectionalGraph = concept g, type G + # The following will also turn the concept into a refinement when it + # comes to overload resolution, but it doesn't provide the convenient + # symbol inheritance + g is IncidendeGraph + + g.incomingEdges(G.VertexType) is Enumerable[G.EdgeType] + + proc f(g: IncidendeGraph) + proc f(g: BidirectionalGraph) # this one will be preferred if we pass a type + # matching the BidirectionalGraph concept + +.. + Converter type classes + ---------------------- + + Concepts can also be used to convert a whole range of types to a single type or + a small set of simpler types. This is achieved with a `return` statement within + the concept body: + + .. code-block:: nim + type + Stringable = concept x + $x is string + return $x + + StringRefValue[CharType] = object + base: ptr CharType + len: int + + StringRef = concept x + # the following would be an overloaded proc for cstring, string, seq and + # other user-defined types, returning either a StringRefValue[char] or + # StringRefValue[wchar] + return makeStringRefValue(x) + + # the varargs param will here be converted to an array of StringRefValues + # the proc will have only two instantiations for the two character types + proc log(format: static[string], varargs[StringRef]) + + # this proc will allow char and wchar values to be mixed in + # the same call at the cost of additional instantiations + # the varargs param will be converted to a tuple + proc log(format: static[string], varargs[distinct StringRef]) + + +.. + VTable types + ------------ + + Concepts allow Nim to define a great number of algorithms, using only + static polymorphism and without erasing any type information or sacrificing + any execution speed. But when polymorphic collections of objects are required, + the user must use one of the provided type erasure techniques - either common + base types or VTable types. + + VTable types are represented as "fat pointers" storing a reference to an + object together with a reference to a table of procs implementing a set of + required operations (the so called vtable). + + In contrast to other programming languages, the vtable in Nim is stored + externally to the object, allowing you to create multiple different vtable + views for the same object. Thus, the polymorphism in Nim is unbounded - + any type can implement an unlimited number of protocols or interfaces not + originally envisioned by the type's author. + + Any concept type can be turned into a VTable type by using the ``vtref`` + or the ``vtptr`` compiler magics. Under the hood, these magics generate + a converter type class, which converts the regular instances of the matching + types to the corresponding VTable type. + + .. code-block:: nim + type + IntEnumerable = vtref Enumerable[int] + + MyObject = object + enumerables: seq[IntEnumerable] + streams: seq[OutputStream.vtref] + + proc addEnumerable(o: var MyObject, e: IntEnumerable) = + o.enumerables.add e + + proc addStream(o: var MyObject, e: OutputStream.vtref) = + o.streams.add e + + The procs that will be included in the vtable are derived from the concept + body and include all proc calls for which all param types were specified as + concrete types. All such calls should include exactly one param of the type + matched against the concept (not necessarily in the first position), which + will be considered the value bound to the vtable. + + Overloads will be created for all captured procs, accepting the vtable type + in the position of the captured underlying object. + + Under these rules, it's possible to obtain a vtable type for a concept with + unbound type parameters or one instantiated with metatypes (type classes), + but it will include a smaller number of captured procs. A completely empty + vtable will be reported as an error. + + The ``vtref`` magic produces types which can be bound to ``ref`` types and + the ``vtptr`` magic produced types bound to ``ptr`` types. + + +Symbol lookup in generics +------------------------- + +Open and Closed symbols +~~~~~~~~~~~~~~~~~~~~~~~ + +The symbol binding rules in generics are slightly subtle: There are "open" and +"closed" symbols. A "closed" symbol cannot be re-bound in the instantiation +context, an "open" symbol can. Per default overloaded symbols are open +and every other symbol is closed. + +Open symbols are looked up in two different contexts: Both the context +at definition and the context at instantiation are considered: + +.. code-block:: nim + type + Index = distinct int + + proc `==` (a, b: Index): bool {.borrow.} + + var a = (0, 0.Index) + var b = (0, 0.Index) + + echo a == b # works! + +In the example the generic ``==`` for tuples (as defined in the system module) +uses the ``==`` operators of the tuple's components. However, the ``==`` for +the ``Index`` type is defined *after* the ``==`` for tuples; yet the example +compiles as the instantiation takes the currently defined symbols into account +too. + +Mixin statement +--------------- + +A symbol can be forced to be open by a `mixin`:idx: declaration: + +.. code-block:: nim + proc create*[T](): ref T = + # there is no overloaded 'init' here, so we need to state that it's an + # open symbol explicitly: + mixin init + new result + init result + + +Bind statement +-------------- + +The ``bind`` statement is the counterpart to the ``mixin`` statement. It +can be used to explicitly declare identifiers that should be bound early (i.e. +the identifiers should be looked up in the scope of the template/generic +definition): + +.. code-block:: nim + # Module A + var + lastId = 0 + + template genId*: untyped = + bind lastId + inc(lastId) + lastId + +.. code-block:: nim + # Module B + import A + + echo genId() + +But a ``bind`` is rarely useful because symbol binding from the definition +scope is the default. + + + +Templates +========= + +A template is a simple form of a macro: It is a simple substitution +mechanism that operates on Nim's abstract syntax trees. It is processed in +the semantic pass of the compiler. + +The syntax to *invoke* a template is the same as calling a procedure. + +Example: + +.. code-block:: nim + template `!=` (a, b: untyped): untyped = + # this definition exists in the System module + not (a == b) + + assert(5 != 6) # the compiler rewrites that to: assert(not (5 == 6)) + +The ``!=``, ``>``, ``>=``, ``in``, ``notin``, ``isnot`` operators are in fact +templates: + +| ``a > b`` is transformed into ``b < a``. +| ``a in b`` is transformed into ``contains(b, a)``. +| ``notin`` and ``isnot`` have the obvious meanings. + +The "types" of templates can be the symbols ``untyped``, +``typed`` or ``typedesc`` (stands for *type +description*). These are "meta types", they can only be used in certain +contexts. Real types can be used too; this implies that ``typed`` expressions +are expected. + + +Typed vs untyped parameters +--------------------------- + +An ``untyped`` parameter means that symbol lookups and type resolution is not +performed before the expression is passed to the template. This means that for +example *undeclared* identifiers can be passed to the template: + +.. code-block:: nim + + template declareInt(x: untyped) = + var x: int + + declareInt(x) # valid + x = 3 + + +.. code-block:: nim + + template declareInt(x: typed) = + var x: int + + declareInt(x) # invalid, because x has not been declared and so has no type + +A template where every parameter is ``untyped`` is called an `immediate`:idx: +template. For historical reasons templates can be explicitly annotated with +an ``immediate`` pragma and then these templates do not take part in +overloading resolution and the parameters' types are *ignored* by the +compiler. Explicit immediate templates are now deprecated. + +**Note**: For historical reasons ``stmt`` is an alias for ``typed`` and +``expr`` an alias for ``untyped``, but new code should use the newer, +clearer names. + + +Passing a code block to a template +---------------------------------- + +You can pass a block of statements as a last parameter to a template via a +special ``:`` syntax: + +.. code-block:: nim + template withFile(f, fn, mode, actions: untyped): untyped = + var f: File + if open(f, fn, mode): + try: + actions + finally: + close(f) + else: + quit("cannot open: " & fn) + + withFile(txt, "ttempl3.txt", fmWrite): + txt.writeLine("line 1") + txt.writeLine("line 2") + +In the example the two ``writeLine`` statements are bound to the ``actions`` +parameter. + + +Usually to pass a block of code to a template the parameter that accepts +the block needs to be of type ``untyped``. Because symbol lookups are then +delayed until template instantiation time: + +.. code-block:: nim + template t(body: typed) = + block: + body + + t: + var i = 1 + echo i + + t: + var i = 2 # fails with 'attempt to redeclare i' + echo i + +The above code fails with the mysterious error message that ``i`` has already +been declared. The reason for this is that the ``var i = ...`` bodies need to +be type-checked before they are passed to the ``body`` parameter and type +checking in Nim implies symbol lookups. For the symbol lookups to succeed +``i`` needs to be added to the current (i.e. outer) scope. After type checking +these additions to the symbol table are not rolled back (for better or worse). +The same code works with ``untyped`` as the passed body is not required to be +type-checked: + +.. code-block:: nim + template t(body: untyped) = + block: + body + + t: + var i = 1 + echo i + + t: + var i = 2 # compiles + echo i + + +Varargs of untyped +------------------ + +In addition to the ``untyped`` meta-type that prevents type checking there is +also ``varargs[untyped]`` so that not even the number of parameters is fixed: + +.. code-block:: nim + template hideIdentifiers(x: varargs[untyped]) = discard + + hideIdentifiers(undeclared1, undeclared2) + +However, since a template cannot iterate over varargs, this feature is +generally much more useful for macros. + +**Note**: For historical reasons ``varargs[expr]`` is not equivalent +to ``varargs[untyped]``. + + +Symbol binding in templates +--------------------------- + +A template is a `hygienic`:idx: macro and so opens a new scope. Most symbols are +bound from the definition scope of the template: + +.. code-block:: nim + # Module A + var + lastId = 0 + + template genId*: untyped = + inc(lastId) + lastId + +.. code-block:: nim + # Module B + import A + + echo genId() # Works as 'lastId' has been bound in 'genId's defining scope + +As in generics symbol binding can be influenced via ``mixin`` or ``bind`` +statements. + + + +Identifier construction +----------------------- + +In templates identifiers can be constructed with the backticks notation: + +.. code-block:: nim + + template typedef(name: untyped, typ: typedesc) = + type + `T name`* {.inject.} = typ + `P name`* {.inject.} = ref `T name` + + typedef(myint, int) + var x: PMyInt + +In the example ``name`` is instantiated with ``myint``, so \`T name\` becomes +``Tmyint``. + + +Lookup rules for template parameters +------------------------------------ + +A parameter ``p`` in a template is even substituted in the expression ``x.p``. +Thus template arguments can be used as field names and a global symbol can be +shadowed by the same argument name even when fully qualified: + +.. code-block:: nim + # module 'm' + + type + Lev = enum + levA, levB + + var abclev = levB + + template tstLev(abclev: Lev) = + echo abclev, " ", m.abclev + + tstLev(levA) + # produces: 'levA levA' + +But the global symbol can properly be captured by a ``bind`` statement: + +.. code-block:: nim + # module 'm' + + type + Lev = enum + levA, levB + + var abclev = levB + + template tstLev(abclev: Lev) = + bind m.abclev + echo abclev, " ", m.abclev + + tstLev(levA) + # produces: 'levA levB' + + +Hygiene in templates +-------------------- + +Per default templates are `hygienic`:idx:\: Local identifiers declared in a +template cannot be accessed in the instantiation context: + +.. code-block:: nim + + template newException*(exceptn: typedesc, message: string): untyped = + var + e: ref exceptn # e is implicitly gensym'ed here + new(e) + e.msg = message + e + + # so this works: + let e = "message" + raise newException(EIO, e) + + +Whether a symbol that is declared in a template is exposed to the instantiation +scope is controlled by the `inject`:idx: and `gensym`:idx: pragmas: gensym'ed +symbols are not exposed but inject'ed are. + +The default for symbols of entity ``type``, ``var``, ``let`` and ``const`` +is ``gensym`` and for ``proc``, ``iterator``, ``converter``, ``template``, +``macro`` is ``inject``. However, if the name of the entity is passed as a +template parameter, it is an inject'ed symbol: + +.. code-block:: nim + template withFile(f, fn, mode: untyped, actions: untyped): untyped = + block: + var f: File # since 'f' is a template param, it's injected implicitly + ... + + withFile(txt, "ttempl3.txt", fmWrite): + txt.writeLine("line 1") + txt.writeLine("line 2") + + +The ``inject`` and ``gensym`` pragmas are second class annotations; they have +no semantics outside of a template definition and cannot be abstracted over: + +.. code-block:: nim + {.pragma myInject: inject.} + + template t() = + var x {.myInject.}: int # does NOT work + + +To get rid of hygiene in templates, one can use the `dirty`:idx: pragma for +a template. ``inject`` and ``gensym`` have no effect in ``dirty`` templates. + + + +Limitations of the method call syntax +------------------------------------- + +The expression ``x`` in ``x.f`` needs to be semantically checked (that means +symbol lookup and type checking) before it can be decided that it needs to be +rewritten to ``f(x)``. Therefore the dot syntax has some limitations when it +is used to invoke templates/macros: + +.. code-block:: nim + template declareVar(name: untyped) = + const name {.inject.} = 45 + + # Doesn't compile: + unknownIdentifier.declareVar + + +Another common example is this: + +.. code-block:: nim + from sequtils import toSeq + + iterator something: string = + yield "Hello" + yield "World" + + var info = toSeq(something()) + +The problem here is that the compiler already decided that ``something()`` as +an iterator is not callable in this context before ``toSeq`` gets its +chance to convert it into a sequence. + + +Macros +====== + +A macro is a special kind of low level template. Macros can be used +to implement `domain specific languages`:idx:. + +While macros enable advanced compile-time code transformations, they +cannot change Nim's syntax. However, this is no real restriction because +Nim's syntax is flexible enough anyway. + +To write macros, one needs to know how the Nim concrete syntax is converted +to an abstract syntax tree. + +There are two ways to invoke a macro: +(1) invoking a macro like a procedure call (`expression macros`) +(2) invoking a macro with the special ``macrostmt`` syntax (`statement macros`) + + +Expression Macros +----------------- + +The following example implements a powerful ``debug`` command that accepts a +variable number of arguments: + +.. code-block:: nim + # to work with Nim syntax trees, we need an API that is defined in the + # ``macros`` module: + import macros + + macro debug(n: varargs[untyped]): untyped = + # `n` is a Nim AST that contains the whole macro invocation + # this macro returns a list of statements: + result = newNimNode(nnkStmtList, n) + # iterate over any argument that is passed to this macro: + for i in 0..n.len-1: + # add a call to the statement list that writes the expression; + # `toStrLit` converts an AST to its string representation: + add(result, newCall("write", newIdentNode("stdout"), toStrLit(n[i]))) + # add a call to the statement list that writes ": " + add(result, newCall("write", newIdentNode("stdout"), newStrLitNode(": "))) + # add a call to the statement list that writes the expressions value: + add(result, newCall("writeLine", newIdentNode("stdout"), n[i])) + + var + a: array [0..10, int] + x = "some string" + a[0] = 42 + a[1] = 45 + + debug(a[0], a[1], x) + +The macro call expands to: + +.. code-block:: nim + write(stdout, "a[0]") + write(stdout, ": ") + writeLine(stdout, a[0]) + + write(stdout, "a[1]") + write(stdout, ": ") + writeLine(stdout, a[1]) + + write(stdout, "x") + write(stdout, ": ") + writeLine(stdout, x) + + +Arguments that are passed to a ``varargs`` parameter are wrapped in an array +constructor expression. This is why ``debug`` iterates over all of ``n``'s +children. + + +BindSym +------- + +The above ``debug`` macro relies on the fact that ``write``, ``writeLine`` and +``stdout`` are declared in the system module and thus visible in the +instantiating context. There is a way to use bound identifiers +(aka `symbols`:idx:) instead of using unbound identifiers. The ``bindSym`` +builtin can be used for that: + +.. code-block:: nim + import macros + + macro debug(n: varargs[typed]): untyped = + result = newNimNode(nnkStmtList, n) + for x in n: + # we can bind symbols in scope via 'bindSym': + add(result, newCall(bindSym"write", bindSym"stdout", toStrLit(x))) + add(result, newCall(bindSym"write", bindSym"stdout", newStrLitNode(": "))) + add(result, newCall(bindSym"writeLine", bindSym"stdout", x)) + + var + a: array [0..10, int] + x = "some string" + a[0] = 42 + a[1] = 45 + + debug(a[0], a[1], x) + +The macro call expands to: + +.. code-block:: nim + write(stdout, "a[0]") + write(stdout, ": ") + writeLine(stdout, a[0]) + + write(stdout, "a[1]") + write(stdout, ": ") + writeLine(stdout, a[1]) + + write(stdout, "x") + write(stdout, ": ") + writeLine(stdout, x) + +However, the symbols ``write``, ``writeLine`` and ``stdout`` are already bound +and are not looked up again. As the example shows, ``bindSym`` does work with +overloaded symbols implicitly. + + +Statement Macros +---------------- + +Statement macros are defined just as expression macros. However, they are +invoked by an expression following a colon. + +The following example outlines a macro that generates a lexical analyzer from +regular expressions: + +.. code-block:: nim + import macros + + macro case_token(n: untyped): untyped = + # creates a lexical analyzer from regular expressions + # ... (implementation is an exercise for the reader :-) + discard + + case_token: # this colon tells the parser it is a macro statement + of r"[A-Za-z_]+[A-Za-z_0-9]*": + return tkIdentifier + of r"0-9+": + return tkInteger + of r"[\+\-\*\?]+": + return tkOperator + else: + return tkUnknown + + +**Style note**: For code readability, it is the best idea to use the least +powerful programming construct that still suffices. So the "check list" is: + +(1) Use an ordinary proc/iterator, if possible. +(2) Else: Use a generic proc/iterator, if possible. +(3) Else: Use a template, if possible. +(4) Else: Use a macro. + + +Macros as pragmas +----------------- + +Whole routines (procs, iterators etc.) can also be passed to a template or +a macro via the pragma notation: + +.. code-block:: nim + template m(s: untyped) = discard + + proc p() {.m.} = discard + +This is a simple syntactic transformation into: + +.. code-block:: nim + template m(s: untyped) = discard + + m: + proc p() = discard + + + +Special Types +============= + +static[T] +--------- + +**Note**: static[T] is still in development. + +As their name suggests, static parameters must be known at compile-time: + +.. code-block:: nim + + proc precompiledRegex(pattern: static[string]): RegEx = + var res {.global.} = re(pattern) + return res + + precompiledRegex("/d+") # Replaces the call with a precompiled + # regex, stored in a global variable + + precompiledRegex(paramStr(1)) # Error, command-line options + # are not known at compile-time + + +For the purposes of code generation, all static params are treated as +generic params - the proc will be compiled separately for each unique +supplied value (or combination of values). + +Static params can also appear in the signatures of generic types: + +.. code-block:: nim + + type + Matrix[M,N: static[int]; T: Number] = array[0..(M*N - 1), T] + # Note how `Number` is just a type constraint here, while + # `static[int]` requires us to supply a compile-time int value + + AffineTransform2D[T] = Matrix[3, 3, T] + AffineTransform3D[T] = Matrix[4, 4, T] + + var m1: AffineTransform3D[float] # OK + var m2: AffineTransform2D[string] # Error, `string` is not a `Number` + + +typedesc +-------- + +`typedesc` is a special type allowing one to treat types as compile-time values +(i.e. if types are compile-time values and all values have a type, then +typedesc must be their type). + +When used as a regular proc param, typedesc acts as a type class. The proc +will be instantiated for each unique type parameter and one can refer to the +instantiation type using the param name: + +.. code-block:: nim + + proc new(T: typedesc): ref T = + echo "allocating ", T.name + new(result) + + var n = Node.new + var tree = new(BinaryTree[int]) + +When multiple typedesc params are present, they act like a distinct type class +(i.e. they will bind freely to different types). To force a bind-once behavior +one can use a named alias or an explicit `typedesc` generic param: + +.. code-block:: nim + proc acceptOnlyTypePairs[T: typedesc, U: typedesc](A, B: T; C, D: U) + +Once bound, typedesc params can appear in the rest of the proc signature: + +.. code-block:: nim + + template declareVariableWithType(T: typedesc, value: T) = + var x: T = value + + declareVariableWithType int, 42 + + +Overload resolution can be further influenced by constraining the set of +types that will match the typedesc param: + +.. code-block:: nim + + template maxval(T: typedesc[int]): int = high(int) + template maxval(T: typedesc[float]): float = Inf + + var i = int.maxval + var f = float.maxval + var s = string.maxval # error, maxval is not implemented for string + +The constraint can be a concrete type or a type class. + + + + +Special Operators +================= + +dot operators +------------- + +**Note**: Dot operators are still experimental and so need to be enabled +via ``{.experimental.}``. + +Nim offers a special family of dot operators that can be used to +intercept and rewrite proc call and field access attempts, referring +to previously undeclared symbol names. They can be used to provide a +fluent interface to objects lying outside the static confines of the +type system such as values from dynamic scripting languages +or dynamic file formats such as JSON or XML. + +When Nim encounters an expression that cannot be resolved by the +standard overload resolution rules, the current scope will be searched +for a dot operator that can be matched against a re-written form of +the expression, where the unknown field or proc name is passed to +an ``untyped`` parameter: + +.. code-block:: nim + a.b # becomes `.`(a, "b") + a.b(c, d) # becomes `.`(a, "b", c, d) + +The matched dot operators can be symbols of any callable kind (procs, +templates and macros), depending on the desired effect: + +.. code-block:: nim + template `.` (js: PJsonNode, field: untyped): JSON = js[astToStr(field)] + + var js = parseJson("{ x: 1, y: 2}") + echo js.x # outputs 1 + echo js.y # outputs 2 + +The following dot operators are available: + +operator `.` +------------ +This operator will be matched against both field accesses and method calls. + +operator `.()` +--------------- +This operator will be matched exclusively against method calls. It has higher +precedence than the `.` operator and this allows one to handle expressions like +`x.y` and `x.y()` differently if one is interfacing with a scripting language +for example. + +operator `.=` +------------- +This operator will be matched against assignments to missing fields. + +.. code-block:: nim + a.b = c # becomes `.=`(a, "b", c) + + + + +Type bound operations +===================== + +There are 3 operations that are bound to a type: + +1. Assignment +2. Destruction +3. Deep copying for communication between threads + +These operations can be *overridden* instead of *overloaded*. This means the +implementation is automatically lifted to structured types. For instance if type +``T`` has an overridden assignment operator ``=`` this operator is also used +for assignments of the type ``seq[T]``. Since these operations are bound to a +type they have to be bound to a nominal type for reasons of simplicity of +implementation: This means an overridden ``deepCopy`` for ``ref T`` is really +bound to ``T`` and not to ``ref T``. This also means that one cannot override +``deepCopy`` for both ``ptr T`` and ``ref T`` at the same time; instead a +helper distinct or object type has to be used for one pointer type. + + +operator `=` +------------ + +This operator is the assignment operator. Note that in the contexts +``result = expr``, ``parameter = defaultValue`` or for +parameter passing no assignment is performed. For a type ``T`` that has an +overloaded assignment operator ``var v = T()`` is rewritten +to ``var v: T; v = T()``; in other words ``var`` and ``let`` contexts do count +as assignments. + +The assignment operator needs to be attached to an object or distinct +type ``T``. Its signature has to be ``(var T, T)``. Example: + +.. code-block:: nim + type + Concrete = object + a, b: string + + proc `=`(d: var Concrete; src: Concrete) = + shallowCopy(d.a, src.a) + shallowCopy(d.b, src.b) + echo "Concrete '=' called" + + var x, y: array[0..2, Concrete] + var cA, cB: Concrete + + var cATup, cBTup: tuple[x: int, ha: Concrete] + + x = y + cA = cB + cATup = cBTup + + + +destructors +----------- + +A destructor must have a single parameter with a concrete type (the name of a +generic type is allowed too). The name of the destructor has to be ``=destroy``. + +``=destroy(v)`` will be automatically invoked for every local stack +variable ``v`` that goes out of scope. + +If a structured type features a field with destructable type and +the user has not provided an explicit implementation, a destructor for the +structured type will be automatically generated. Calls to any base class +destructors in both user-defined and generated destructors will be inserted. + +A destructor is attached to the type it destructs; expressions of this type +can then only be used in *destructible contexts* and as parameters: + +.. code-block:: nim + type + MyObj = object + x, y: int + p: pointer + + proc `=destroy`(o: var MyObj) = + if o.p != nil: dealloc o.p + + proc open: MyObj = + result = MyObj(x: 1, y: 2, p: alloc(3)) + + proc work(o: MyObj) = + echo o.x + # No destructor invoked here for 'o' as 'o' is a parameter. + + proc main() = + # destructor automatically invoked at the end of the scope: + var x = open() + # valid: pass 'x' to some other proc: + work(x) + + # Error: usage of a type with a destructor in a non destructible context + echo open() + +A destructible context is currently only the following: + +1. The ``expr`` in ``var x = expr``. +2. The ``expr`` in ``let x = expr``. +3. The ``expr`` in ``return expr``. +4. The ``expr`` in ``result = expr`` where ``result`` is the special symbol + introduced by the compiler. + +These rules ensure that the construction is tied to a variable and can easily +be destructed at its scope exit. Later versions of the language will improve +the support of destructors. + +Be aware that destructors are not called for objects allocated with ``new``. +This may change in future versions of language, but for now the `finalizer`:idx: +parameter to ``new`` has to be used. + +**Note**: Destructors are still experimental and the spec might change +significantly in order to incorporate an escape analysis. + + +deepCopy +-------- + +``=deepCopy`` is a builtin that is invoked whenever data is passed to +a ``spawn``'ed proc to ensure memory safety. The programmer can override its +behaviour for a specific ``ref`` or ``ptr`` type ``T``. (Later versions of the +language may weaken this restriction.) + +The signature has to be: + +.. code-block:: nim + proc `=deepCopy`(x: T): T + +This mechanism will be used by most data structures that support shared memory +like channels to implement thread safe automatic memory management. + +The builtin ``deepCopy`` can even clone closures and their environments. See +the documentation of `spawn`_ for details. + + +Term rewriting macros +===================== + +Term rewriting macros are macros or templates that have not only +a *name* but also a *pattern* that is searched for after the semantic checking +phase of the compiler: This means they provide an easy way to enhance the +compilation pipeline with user defined optimizations: + +.. code-block:: nim + template optMul{`*`(a, 2)}(a: int): int = a+a + + let x = 3 + echo x * 2 + +The compiler now rewrites ``x * 2`` as ``x + x``. The code inside the +curlies is the pattern to match against. The operators ``*``, ``**``, +``|``, ``~`` have a special meaning in patterns if they are written in infix +notation, so to match verbatim against ``*`` the ordinary function call syntax +needs to be used. + + +Unfortunately optimizations are hard to get right and even the tiny example +is **wrong**: + +.. code-block:: nim + template optMul{`*`(a, 2)}(a: int): int = a+a + + proc f(): int = + echo "side effect!" + result = 55 + + echo f() * 2 + +We cannot duplicate 'a' if it denotes an expression that has a side effect! +Fortunately Nim supports side effect analysis: + +.. code-block:: nim + template optMul{`*`(a, 2)}(a: int{noSideEffect}): int = a+a + + proc f(): int = + echo "side effect!" + result = 55 + + echo f() * 2 # not optimized ;-) + +You can make one overload matching with a constraint and one without, and the +one with a constraint will have precedence, and so you can handle both cases +differently. + +So what about ``2 * a``? We should tell the compiler ``*`` is commutative. We +cannot really do that however as the following code only swaps arguments +blindly: + +.. code-block:: nim + template mulIsCommutative{`*`(a, b)}(a, b: int): int = b*a + +What optimizers really need to do is a *canonicalization*: + +.. code-block:: nim + template canonMul{`*`(a, b)}(a: int{lit}, b: int): int = b*a + +The ``int{lit}`` parameter pattern matches against an expression of +type ``int``, but only if it's a literal. + + + +Parameter constraints +--------------------- + +The `parameter constraint`:idx: expression can use the operators ``|`` (or), +``&`` (and) and ``~`` (not) and the following predicates: + +=================== ===================================================== +Predicate Meaning +=================== ===================================================== +``atom`` The matching node has no children. +``lit`` The matching node is a literal like "abc", 12. +``sym`` The matching node must be a symbol (a bound + identifier). +``ident`` The matching node must be an identifier (an unbound + identifier). +``call`` The matching AST must be a call/apply expression. +``lvalue`` The matching AST must be an lvalue. +``sideeffect`` The matching AST must have a side effect. +``nosideeffect`` The matching AST must have no side effect. +``param`` A symbol which is a parameter. +``genericparam`` A symbol which is a generic parameter. +``module`` A symbol which is a module. +``type`` A symbol which is a type. +``var`` A symbol which is a variable. +``let`` A symbol which is a ``let`` variable. +``const`` A symbol which is a constant. +``result`` The special ``result`` variable. +``proc`` A symbol which is a proc. +``method`` A symbol which is a method. +``iterator`` A symbol which is an iterator. +``converter`` A symbol which is a converter. +``macro`` A symbol which is a macro. +``template`` A symbol which is a template. +``field`` A symbol which is a field in a tuple or an object. +``enumfield`` A symbol which is a field in an enumeration. +``forvar`` A for loop variable. +``label`` A label (used in ``block`` statements). +``nk*`` The matching AST must have the specified kind. + (Example: ``nkIfStmt`` denotes an ``if`` statement.) +``alias`` States that the marked parameter needs to alias + with *some* other parameter. +``noalias`` States that *every* other parameter must not alias + with the marked parameter. +=================== ===================================================== + +Predicates that share their name with a keyword have to be escaped with +backticks: `` `const` ``. +The ``alias`` and ``noalias`` predicates refer not only to the matching AST, +but also to every other bound parameter; syntactically they need to occur after +the ordinary AST predicates: + +.. code-block:: nim + template ex{a = b + c}(a: int{noalias}, b, c: int) = + # this transformation is only valid if 'b' and 'c' do not alias 'a': + a = b + inc a, c + + +Pattern operators +----------------- + +The operators ``*``, ``**``, ``|``, ``~`` have a special meaning in patterns +if they are written in infix notation. + + +The ``|`` operator +~~~~~~~~~~~~~~~~~~ + +The ``|`` operator if used as infix operator creates an ordered choice: + +.. code-block:: nim + template t{0|1}(): untyped = 3 + let a = 1 + # outputs 3: + echo a + +The matching is performed after the compiler performed some optimizations like +constant folding, so the following does not work: + +.. code-block:: nim + template t{0|1}(): untyped = 3 + # outputs 1: + echo 1 + +The reason is that the compiler already transformed the 1 into "1" for +the ``echo`` statement. However, a term rewriting macro should not change the +semantics anyway. In fact they can be deactivated with the ``--patterns:off`` +command line option or temporarily with the ``patterns`` pragma. + + +The ``{}`` operator +~~~~~~~~~~~~~~~~~~~ + +A pattern expression can be bound to a pattern parameter via the ``expr{param}`` +notation: + +.. code-block:: nim + template t{(0|1|2){x}}(x: untyped): untyped = x+1 + let a = 1 + # outputs 2: + echo a + + +The ``~`` operator +~~~~~~~~~~~~~~~~~~ + +The ``~`` operator is the **not** operator in patterns: + +.. code-block:: nim + template t{x = (~x){y} and (~x){z}}(x, y, z: bool) = + x = y + if x: x = z + + var + a = false + b = true + c = false + a = b and c + echo a + + +The ``*`` operator +~~~~~~~~~~~~~~~~~~ + +The ``*`` operator can *flatten* a nested binary expression like ``a & b & c`` +to ``&(a, b, c)``: + +.. code-block:: nim + var + calls = 0 + + proc `&&`(s: varargs[string]): string = + result = s[0] + for i in 1..len(s)-1: result.add s[i] + inc calls + + template optConc{ `&&` * a }(a: string): untyped = &&a + + let space = " " + echo "my" && (space & "awe" && "some " ) && "concat" + + # check that it's been optimized properly: + doAssert calls == 1 + + +The second operator of `*` must be a parameter; it is used to gather all the +arguments.

If a +parameter is of the type ``varargs`` it is treated specially and it can match +0 or more arguments in the AST to be matched against: + +.. code-block:: nim + template optWrite{ + write(f, x) + ((write|writeLine){w})(f, y) + }(x, y: varargs[untyped], f: File, w: untyped) = + w(f, x, y) + + + +Example: Partial evaluation +--------------------------- + +The following example shows how some simple partial evaluation can be +implemented with term rewriting: + +.. code-block:: nim + proc p(x, y: int; cond: bool): int = + result = if cond: x + y else: x - y + + template optP1{p(x, y, true)}(x, y: untyped): untyped = x + y + template optP2{p(x, y, false)}(x, y: untyped): untyped = x - y + + +Example: Hoisting +----------------- + +The following example shows how some form of hoisting can be implemented: + +.. code-block:: nim + import pegs + + template optPeg{peg(pattern)}(pattern: string{lit}): Peg = + var gl {.global, gensym.} = peg(pattern) + gl + + for i in 0 .. 3: + echo match("(a b c)", peg"'(' @ ')'") + echo match("W_HI_Le", peg"\y 'while'") + +The ``optPeg`` template optimizes the case of a peg constructor with a string +literal, so that the pattern will only be parsed once at program startup and +stored in a global ``gl`` which is then re-used. This optimization is called +hoisting because it is comparable to classical loop hoisting. + + +AST based overloading +===================== + +Parameter constraints can also be used for ordinary routine parameters; these +constraints affect ordinary overloading resolution then: + +.. code-block:: nim + proc optLit(a: string{lit|`const`}) = + echo "string literal" + proc optLit(a: string) = + echo "no string literal" + + const + constant = "abc" + + var + variable = "xyz" + + optLit("literal") + optLit(constant) + optLit(variable) + +However, the constraints ``alias`` and ``noalias`` are not available in +ordinary routines. + + +Move optimization +----------------- + +The ``call`` constraint is particularly useful to implement a move +optimization for types that have copying semantics: + +.. code-block:: nim + proc `[]=`*(t: var Table, key: string, val: string) = + ## puts a (key, value)-pair into `t`. The semantics of string require + ## a copy here: + let idx = findInsertionPosition(key) + t[idx].key = key + t[idx].val = val + + proc `[]=`*(t: var Table, key: string{call}, val: string{call}) = + ## puts a (key, value)-pair into `t`. Optimized version that knows that + ## the strings are unique and thus don't need to be copied: + let idx = findInsertionPosition(key) + shallowCopy t[idx].key, key + shallowCopy t[idx].val, val + + var t: Table + # overloading resolution ensures that the optimized []= is called here: + t[f()] = g() + + + +Modules +======= +Nim supports splitting a program into pieces by a module concept. +Each module needs to be in its own file and has its own `namespace`:idx:. +Modules enable `information hiding`:idx: and `separate compilation`:idx:. +A module may gain access to symbols of another module by the `import`:idx: +statement. `Recursive module dependencies`:idx: are allowed, but slightly +subtle. Only top-level symbols that are marked with an asterisk (``*``) are +exported. A valid module name can only be a valid Nim identifier (and thus its +filename is ``identifier.nim``). + +The algorithm for compiling modules is: + +- compile the whole module as usual, following import statements recursively + +- if there is a cycle only import the already parsed symbols (that are + exported); if an unknown identifier occurs then abort + +This is best illustrated by an example: + +.. code-block:: nim + # Module A + type + T1* = int # Module A exports the type ``T1`` + import B # the compiler starts parsing B + + proc main() = + var i = p(3) # works because B has been parsed completely here + + main() + + +.. code-block:: nim + # Module B + import A # A is not parsed here! Only the already known symbols + # of A are imported. + + proc p*(x: A.T1): A.T1 = + # this works because the compiler has already + # added T1 to A's interface symbol table + result = x + 1 + + +Import statement +~~~~~~~~~~~~~~~~ + +After the ``import`` statement a list of module names can follow or a single +module name followed by an ``except`` list to prevent some symbols to be +imported: + +.. code-block:: nim + import strutils except `%`, toUpper + + # doesn't work then: + echo "$1" % "abc".toUpper + + +It is not checked that the ``except`` list is really exported from the module. +This feature allows to compile against an older version of the module that +does not export these identifiers. + + +Include statement +~~~~~~~~~~~~~~~~~ +The ``include`` statement does something fundamentally different than +importing a module: it merely includes the contents of a file. The ``include`` +statement is useful to split up a large module into several files: + +.. code-block:: nim + include fileA, fileB, fileC + + + +Module names in imports +~~~~~~~~~~~~~~~~~~~~~~~ + +A module alias can be introduced via the ``as`` keyword: + +.. code-block:: nim + import strutils as su, sequtils as qu + + echo su.format("$1", "lalelu") + +The original module name is then not accessible. The +notations ``path/to/module`` or ``path.to.module`` or ``"path/to/module"`` +can be used to refer to a module in subdirectories: + +.. code-block:: nim + import lib.pure.strutils, lib/pure/os, "lib/pure/times" + +Note that the module name is still ``strutils`` and not ``lib.pure.strutils`` +and so one **cannot** do: + +.. code-block:: nim + import lib.pure.strutils + echo lib.pure.strutils + +Likewise the following does not make sense as the name is ``strutils`` already: + +.. code-block:: nim + import lib.pure.strutils as strutils + + +From import statement +~~~~~~~~~~~~~~~~~~~~~ + +After the ``from`` statement a module name follows followed by +an ``import`` to list the symbols one likes to use without explicit +full qualification: + +.. code-block:: nim + from strutils import `%` + + echo "$1" % "abc" + # always possible: full qualification: + echo strutils.replace("abc", "a", "z") + +It's also possible to use ``from module import nil`` if one wants to import +the module but wants to enforce fully qualified access to every symbol +in ``module``. + + +Export statement +~~~~~~~~~~~~~~~~ + +An ``export`` statement can be used for symbol forwarding so that client +modules don't need to import a module's dependencies: + +.. code-block:: nim + # module B + type MyObject* = object + +.. code-block:: nim + # module A + import B + export B.MyObject + + proc `$`*(x: MyObject): string = "my object" + + +.. code-block:: nim + # module C + import A + + # B.MyObject has been imported implicitly here: + var x: MyObject + echo $x + +Note on paths +----------- +In module related statements, if any part of the module name / +path begins with a number, you may have to quote it in double quotes. +In the following example, it would be seen as a literal number '3.0' of type +'float64' if not quoted, if uncertain - quote it: + +.. code-block:: nim + import "gfx/3d/somemodule" + + +Scope rules +----------- +Identifiers are valid from the point of their declaration until the end of +the block in which the declaration occurred. The range where the identifier +is known is the scope of the identifier. The exact scope of an +identifier depends on the way it was declared. + +Block scope +~~~~~~~~~~~ +The *scope* of a variable declared in the declaration part of a block +is valid from the point of declaration until the end of the block. If a +block contains a second block, in which the identifier is redeclared, +then inside this block, the second declaration will be valid. Upon +leaving the inner block, the first declaration is valid again. An +identifier cannot be redefined in the same block, except if valid for +procedure or iterator overloading purposes. + + +Tuple or object scope +~~~~~~~~~~~~~~~~~~~~~ +The field identifiers inside a tuple or object definition are valid in the +following places: + +* To the end of the tuple/object definition. +* Field designators of a variable of the given tuple/object type. +* In all descendant types of the object type. + +Module scope +~~~~~~~~~~~~ +All identifiers of a module are valid from the point of declaration until +the end of the module. Identifiers from indirectly dependent modules are *not* +available. The `system`:idx: module is automatically imported in every module. + +If a module imports an identifier by two different modules, each occurrence of +the identifier has to be qualified, unless it is an overloaded procedure or +iterator in which case the overloading resolution takes place: + +.. code-block:: nim + # Module A + var x*: string + +.. code-block:: nim + # Module B + var x*: int + +.. code-block:: nim + # Module C + import A, B + write(stdout, x) # error: x is ambiguous + write(stdout, A.x) # no error: qualifier used + + var x = 4 + write(stdout, x) # not ambiguous: uses the module C's x + + +Compiler Messages +================= + +The Nim compiler emits different kinds of messages: `hint`:idx:, +`warning`:idx:, and `error`:idx: messages. An *error* message is emitted if +the compiler encounters any static error. + + + +Pragmas +======= + +Pragmas are Nim's method to give the compiler additional information / +commands without introducing a massive number of new keywords. Pragmas are +processed on the fly during semantic checking. Pragmas are enclosed in the +special ``{.`` and ``.}`` curly brackets. Pragmas are also often used as a +first implementation to play with a language feature before a nicer syntax +to access the feature becomes available. + + +deprecated pragma +----------------- + +The deprecated pragma is used to mark a symbol as deprecated: + +.. code-block:: nim + proc p() {.deprecated.} + var x {.deprecated.}: char + +It can also be used as a statement, in that case it takes a list of *renamings*. + +.. code-block:: nim + type + File = object + Stream = ref object + {.deprecated: [TFile: File, PStream: Stream].} + + +noSideEffect pragma +------------------- +The ``noSideEffect`` pragma is used to mark a proc/iterator to have no side +effects. This means that the proc/iterator only changes locations that are +reachable from its parameters and the return value only depends on the +arguments. If none of its parameters have the type ``var T`` +or ``ref T`` or ``ptr T`` this means no locations are modified. It is a static +error to mark a proc/iterator to have no side effect if the compiler cannot +verify this. + +As a special semantic rule, the built-in `debugEcho `_ +pretends to be free of side effects, so that it can be used for debugging +routines marked as ``noSideEffect``. + +**Future directions**: ``func`` may become a keyword and syntactic sugar for a +proc with no side effects: + +.. code-block:: nim + func `+` (x, y: int): int + + +destructor pragma +----------------- + +The ``destructor`` pragma is used to mark a proc to act as a type destructor. +Its usage is deprecated, see `type bound operations`_ instead. + +override pragma +--------------- + +See `type bound operations`_ instead. + +procvar pragma +-------------- +The ``procvar`` pragma is used to mark a proc that it can be passed to a +procedural variable. + + +compileTime pragma +------------------ +The ``compileTime`` pragma is used to mark a proc or variable to be used at +compile time only. No code will be generated for it. Compile time procs are +useful as helpers for macros. Since version 0.12.0 of the language, a proc +that uses ``system.NimNode`` within its parameter types is implicitly declared +``compileTime``: + +.. code-block:: nim + proc astHelper(n: NimNode): NimNode = + result = n + +Is the same as: + +.. code-block:: nim + proc astHelper(n: NimNode): NimNode {.compileTime.} = + result = n + + +noReturn pragma +--------------- +The ``noreturn`` pragma is used to mark a proc that never returns. + + +acyclic pragma +-------------- +The ``acyclic`` pragma can be used for object types to mark them as acyclic +even though they seem to be cyclic. This is an **optimization** for the garbage +collector to not consider objects of this type as part of a cycle: + +.. code-block:: nim + type + Node = ref NodeObj + NodeObj {.acyclic, final.} = object + left, right: Node + data: string + +Or if we directly use a ref object: + +.. code-block:: nim + type + Node = ref object {.acyclic, final.} + left, right: Node + data: string + +In the example a tree structure is declared with the ``Node`` type. Note that +the type definition is recursive and the GC has to assume that objects of +this type may form a cyclic graph. The ``acyclic`` pragma passes the +information that this cannot happen to the GC. If the programmer uses the +``acyclic`` pragma for data types that are in reality cyclic, the GC may leak +memory, but nothing worse happens. + +**Future directions**: The ``acyclic`` pragma may become a property of a +``ref`` type: + +.. code-block:: nim + type + Node = acyclic ref NodeObj + NodeObj = object + left, right: Node + data: string + + +final pragma +------------ +The ``final`` pragma can be used for an object type to specify that it +cannot be inherited from. + + +shallow pragma +-------------- +The ``shallow`` pragma affects the semantics of a type: The compiler is +allowed to make a shallow copy. This can cause serious semantic issues and +break memory safety! However, it can speed up assignments considerably, +because the semantics of Nim require deep copying of sequences and strings. +This can be expensive, especially if sequences are used to build a tree +structure: + +.. code-block:: nim + type + NodeKind = enum nkLeaf, nkInner + Node {.final, shallow.} = object + case kind: NodeKind + of nkLeaf: + strVal: string + of nkInner: + children: seq[Node] + + +pure pragma +----------- +An object type can be marked with the ``pure`` pragma so that its type +field which is used for runtime type identification is omitted. This used to be +necessary for binary compatibility with other compiled languages. + +An enum type can be marked as ``pure``. Then access of its fields always +requires full qualification. + + +asmNoStackFrame pragma +---------------------- +A proc can be marked with the ``asmNoStackFrame`` pragma to tell the compiler +it should not generate a stack frame for the proc. There are also no exit +statements like ``return result;`` generated and the generated C function is +declared as ``__declspec(naked)`` or ``__attribute__((naked))`` (depending on +the used C compiler). + +**Note**: This pragma should only be used by procs which consist solely of +assembler statements. + +error pragma +------------ +The ``error`` pragma is used to make the compiler output an error message +with the given content. Compilation does not necessarily abort after an error +though. + +The ``error`` pragma can also be used to +annotate a symbol (like an iterator or proc). The *usage* of the symbol then +triggers a compile-time error. This is especially useful to rule out that some +operation is valid due to overloading and type conversions: + +.. code-block:: nim + ## check that underlying int values are compared and not the pointers: + proc `==`(x, y: ptr int): bool {.error.} + + +fatal pragma +------------ +The ``fatal`` pragma is used to make the compiler output an error message +with the given content. In contrast to the ``error`` pragma, compilation +is guaranteed to be aborted by this pragma. Example: + +.. code-block:: nim + when not defined(objc): + {.fatal: "Compile this program with the objc command!".} + +warning pragma +-------------- +The ``warning`` pragma is used to make the compiler output a warning message +with the given content. Compilation continues after the warning. + +hint pragma +----------- +The ``hint`` pragma is used to make the compiler output a hint message with +the given content. Compilation continues after the hint. + +line pragma +----------- +The ``line`` pragma can be used to affect line information of the annotated +statement as seen in stack backtraces: + +.. code-block:: nim + + template myassert*(cond: untyped, msg = "") = + if not cond: + # change run-time line information of the 'raise' statement: + {.line: InstantiationInfo().}: + raise newException(EAssertionFailed, msg) + +If the ``line`` pragma is used with a parameter, the parameter needs be a +``tuple[filename: string, line: int]``. If it is used without a parameter, +``system.InstantiationInfo()`` is used. + + +linearScanEnd pragma +-------------------- +The ``linearScanEnd`` pragma can be used to tell the compiler how to +compile a Nim `case`:idx: statement. Syntactically it has to be used as a +statement: + +.. code-block:: nim + case myInt + of 0: + echo "most common case" + of 1: + {.linearScanEnd.} + echo "second most common case" + of 2: echo "unlikely: use branch table" + else: echo "unlikely too: use branch table for ", myInt + +In the example, the case branches ``0`` and ``1`` are much more common than +the other cases. Therefore the generated assembler code should test for these +values first, so that the CPU's branch predictor has a good chance to succeed +(avoiding an expensive CPU pipeline stall). The other cases might be put into a +jump table for O(1) overhead, but at the cost of a (very likely) pipeline +stall. + +The ``linearScanEnd`` pragma should be put into the last branch that should be +tested against via linear scanning. If put into the last branch of the +whole ``case`` statement, the whole ``case`` statement uses linear scanning. + + +computedGoto pragma +------------------- +The ``computedGoto`` pragma can be used to tell the compiler how to +compile a Nim `case`:idx: in a ``while true`` statement. +Syntactically it has to be used as a statement inside the loop: + +.. code-block:: nim + + type + MyEnum = enum + enumA, enumB, enumC, enumD, enumE + + proc vm() = + var instructions: array [0..100, MyEnum] + instructions[2] = enumC + instructions[3] = enumD + instructions[4] = enumA + instructions[5] = enumD + instructions[6] = enumC + instructions[7] = enumA + instructions[8] = enumB + + instructions[12] = enumE + var pc = 0 + while true: + {.computedGoto.} + let instr = instructions[pc] + case instr + of enumA: + echo "yeah A" + of enumC, enumD: + echo "yeah CD" + of enumB: + echo "yeah B" + of enumE: + break + inc(pc) + + vm() + +As the example shows ``computedGoto`` is mostly useful for interpreters. If +the underlying backend (C compiler) does not support the computed goto +extension the pragma is simply ignored. + + +unroll pragma +------------- +The ``unroll`` pragma can be used to tell the compiler that it should unroll +a `for`:idx: or `while`:idx: loop for runtime efficiency: + +.. code-block:: nim + proc searchChar(s: string, c: char): int = + for i in 0 .. s.high: + {.unroll: 4.} + if s[i] == c: return i + result = -1 + +In the above example, the search loop is unrolled by a factor 4. The unroll +factor can be left out too; the compiler then chooses an appropriate unroll +factor. + +**Note**: Currently the compiler recognizes but ignores this pragma. + + +immediate pragma +---------------- + +See `Typed vs untyped parameters`_. + + +compilation option pragmas +-------------------------- +The listed pragmas here can be used to override the code generation options +for a proc/method/converter. + +The implementation currently provides the following possible options (various +others may be added later). + +=============== =============== ============================================ +pragma allowed values description +=============== =============== ============================================ +checks on|off Turns the code generation for all runtime + checks on or off. +boundChecks on|off Turns the code generation for array bound + checks on or off. +overflowChecks on|off Turns the code generation for over- or + underflow checks on or off. +nilChecks on|off Turns the code generation for nil pointer + checks on or off. +assertions on|off Turns the code generation for assertions + on or off. +warnings on|off Turns the warning messages of the compiler + on or off. +hints on|off Turns the hint messages of the compiler + on or off. +optimization none|speed|size Optimize the code for speed or size, or + disable optimization. +patterns on|off Turns the term rewriting templates/macros + on or off. +callconv cdecl|... Specifies the default calling convention for + all procedures (and procedure types) that + follow. +=============== =============== ============================================ + +Example: + +.. code-block:: nim + {.checks: off, optimization: speed.} + # compile without runtime checks and optimize for speed + + +push and pop pragmas +-------------------- +The `push/pop`:idx: pragmas are very similar to the option directive, +but are used to override the settings temporarily. Example: + +.. code-block:: nim + {.push checks: off.} + # compile this section without runtime checks as it is + # speed critical + # ... some code ... + {.pop.} # restore old settings + + +register pragma +--------------- +The ``register`` pragma is for variables only. It declares the variable as +``register``, giving the compiler a hint that the variable should be placed +in a hardware register for faster access. C compilers usually ignore this +though and for good reasons: Often they do a better job without it anyway. + +In highly specific cases (a dispatch loop of a bytecode interpreter for +example) it may provide benefits, though. + + +global pragma +------------- +The ``global`` pragma can be applied to a variable within a proc to instruct +the compiler to store it in a global location and initialize it once at program +startup. + +.. code-block:: nim + proc isHexNumber(s: string): bool = + var pattern {.global.} = re"[0-9a-fA-F]+" + result = s.match(pattern) + +When used within a generic proc, a separate unique global variable will be +created for each instantiation of the proc. The order of initialization of +the created global variables within a module is not defined, but all of them +will be initialized after any top-level variables in their originating module +and before any variable in a module that imports it. + +deadCodeElim pragma +------------------- +The ``deadCodeElim`` pragma only applies to whole modules: It tells the +compiler to activate (or deactivate) dead code elimination for the module the +pragma appears in. + +The ``--deadCodeElim:on`` command line switch has the same effect as marking +every module with ``{.deadCodeElim:on}``. However, for some modules such as +the GTK wrapper it makes sense to *always* turn on dead code elimination - +no matter if it is globally active or not. + +Example: + +.. code-block:: nim + {.deadCodeElim: on.} + + +.. + NoForward pragma + ---------------- + The ``noforward`` pragma can be used to turn on and off a special compilation + mode that to large extent eliminates the need for forward declarations. In this + mode, the proc definitions may appear out of order and the compiler will postpone + their semantic analysis and compilation until it actually needs to generate code + using the definitions. In this regard, this mode is similar to the modus operandi + of dynamic scripting languages, where the function calls are not resolved until + the code is executed. Here is the detailed algorithm taken by the compiler: + + 1. When a callable symbol is first encountered, the compiler will only note the + symbol callable name and it will add it to the appropriate overload set in the + current scope. At this step, it won't try to resolve any of the type expressions + used in the signature of the symbol (so they can refer to other not yet defined + symbols). + + 2. When a top level call is encountered (usually at the very end of the module), + the compiler will try to determine the actual types of all of the symbols in the + matching overload set. This is a potentially recursive process as the signatures + of the symbols may include other call expressions, whose types will be resolved + at this point too. + + 3. Finally, after the best overload is picked, the compiler will start + compiling the body of the respective symbol. This in turn will lead the + compiler to discover more call expressions that need to be resolved and steps + 2 and 3 will be repeated as necessary. + + Please note that if a callable symbol is never used in this scenario, its body + will never be compiled. This is the default behavior leading to best compilation + times, but if exhaustive compilation of all definitions is required, using + ``nim check`` provides this option as well. + + Example: + + .. code-block:: nim + + {.noforward: on.} + + proc foo(x: int) = + bar x + + proc bar(x: int) = + echo x + + foo(10) + + +pragma pragma +------------- + +The ``pragma`` pragma can be used to declare user defined pragmas. This is +useful because Nim's templates and macros do not affect pragmas. User +defined pragmas are in a different module-wide scope than all other symbols. +They cannot be imported from a module. + +Example: + +.. code-block:: nim + when appType == "lib": + {.pragma: rtl, exportc, dynlib, cdecl.} + else: + {.pragma: rtl, importc, dynlib: "client.dll", cdecl.} + + proc p*(a, b: int): int {.rtl.} = + result = a+b + +In the example a new pragma named ``rtl`` is introduced that either imports +a symbol from a dynamic library or exports the symbol for dynamic library +generation. + + +Disabling certain messages +-------------------------- +Nim generates some warnings and hints ("line too long") that may annoy the +user. A mechanism for disabling certain messages is provided: Each hint +and warning message contains a symbol in brackets. This is the message's +identifier that can be used to enable or disable it: + +.. code-block:: Nim + {.hint[LineTooLong]: off.} # turn off the hint about too long lines + +This is often better than disabling all warnings at once. + + +used pragma +----------- + +Nim produces a warning for symbols that are not exported and not used either. +The ``used`` pragma can be attached to a symbol to suppress this warning. This +is particularly useful when the symbol was generated by a macro: + +.. code-block:: nim + template implementArithOps(T) = + proc echoAdd(a, b: T) {.used.} = + echo a + b + proc echoSub(a, b: T) {.used.} = + echo a - b + + # no warning produced for the unused 'echoSub' + implementArithOps(int) + echoAdd 3, 5 + + + +experimental pragma +------------------- + +The ``experimental`` pragma enables experimental language features. Depending +on the concrete feature this means that the feature is either considered +too unstable for an otherwise stable release or that the future of the feature +is uncertain (it may be removed any time). + +Example: + +.. code-block:: nim + {.experimental.} + type + FooId = distinct int + BarId = distinct int + using + foo: FooId + bar: BarId + + proc useUsing(bar, foo) = + echo "bar is of type BarId" + echo "foo is of type FooId" + + +Implementation Specific Pragmas +=============================== + +This section describes additional pragmas that the current Nim implementation +supports but which should not be seen as part of the language specification. + +Bitsize pragma +-------------- + +The ``bitsize`` pragma is for object field members. It declares the field as +a bitfield in C/C++. + +.. code-block:: Nim + type + mybitfield = object + flag {.bitsize:1.}: cuint + +generates: + +.. code-block:: C + struct mybitfield { + unsigned int flag:1; + }; + + +Volatile pragma +--------------- +The ``volatile`` pragma is for variables only. It declares the variable as +``volatile``, whatever that means in C/C++ (its semantics are not well defined +in C/C++). + +**Note**: This pragma will not exist for the LLVM backend. + + +NoDecl pragma +------------- +The ``noDecl`` pragma can be applied to almost any symbol (variable, proc, +type, etc.) and is sometimes useful for interoperability with C: +It tells Nim that it should not generate a declaration for the symbol in +the C code. For example: + +.. code-block:: Nim + var + EACCES {.importc, noDecl.}: cint # pretend EACCES was a variable, as + # Nim does not know its value + +However, the ``header`` pragma is often the better alternative. + +**Note**: This will not work for the LLVM backend. + + +Header pragma +------------- +The ``header`` pragma is very similar to the ``noDecl`` pragma: It can be +applied to almost any symbol and specifies that it should not be declared +and instead the generated code should contain an ``#include``: + +.. code-block:: Nim + type + PFile {.importc: "FILE*", header: "".} = distinct pointer + # import C's FILE* type; Nim will treat it as a new pointer type + +The ``header`` pragma always expects a string constant. The string contant +contains the header file: As usual for C, a system header file is enclosed +in angle brackets: ``<>``. If no angle brackets are given, Nim +encloses the header file in ``""`` in the generated C code. + +**Note**: This will not work for the LLVM backend. + + +IncompleteStruct pragma +----------------------- +The ``incompleteStruct`` pragma tells the compiler to not use the +underlying C ``struct`` in a ``sizeof`` expression: + +.. code-block:: Nim + type + DIR* {.importc: "DIR", header: "", + final, pure, incompleteStruct.} = object + + +Compile pragma +-------------- +The ``compile`` pragma can be used to compile and link a C/C++ source file +with the project: + +.. code-block:: Nim + {.compile: "myfile.cpp".} + +**Note**: Nim computes a SHA1 checksum and only recompiles the file if it +has changed. You can use the ``-f`` command line option to force recompilation +of the file. + + +Link pragma +----------- +The ``link`` pragma can be used to link an additional file with the project: + +.. code-block:: Nim + {.link: "myfile.o".} + + +PassC pragma +------------ +The ``passC`` pragma can be used to pass additional parameters to the C +compiler like you would using the commandline switch ``--passC``: + +.. code-block:: Nim + {.passC: "-Wall -Werror".} + +Note that you can use ``gorge`` from the `system module `_ to +embed parameters from an external command at compile time: + +.. code-block:: Nim + {.passC: gorge("pkg-config --cflags sdl").} + +PassL pragma +------------ +The ``passL`` pragma can be used to pass additional parameters to the linker +like you would using the commandline switch ``--passL``: + +.. code-block:: Nim + {.passL: "-lSDLmain -lSDL".} + +Note that you can use ``gorge`` from the `system module `_ to +embed parameters from an external command at compile time: + +.. code-block:: Nim + {.passL: gorge("pkg-config --libs sdl").} + + +Emit pragma +----------- +The ``emit`` pragma can be used to directly affect the output of the +compiler's code generator. So it makes your code unportable to other code +generators/backends. Its usage is highly discouraged! However, it can be +extremely useful for interfacing with `C++`:idx: or `Objective C`:idx: code. + +Example: + +.. code-block:: Nim + {.emit: """ + static int cvariable = 420; + """.} + + {.push stackTrace:off.} + proc embedsC() = + var nimVar = 89 + # access Nim symbols within an emit section outside of string literals: + {.emit: ["""fprintf(stdout, "%d\n", cvariable + (int)""", nimVar, ");"].} + {.pop.} + + embedsC() + +For backwards compatibility, if the argument to the ``emit`` statement +is a single string literal, Nim symbols can be referred to via backticks. +This usage is however deprecated. + +For a toplevel emit statement the section where in the generated C/C++ file +the code should be emitted can be influenced via the +prefixes ``/*TYPESECTION*/`` or ``/*VARSECTION*/`` or ``/*INCLUDESECTION*/``: + +.. code-block:: Nim + {.emit: """/*TYPESECTION*/ + struct Vector3 { + public: + Vector3(): x(5) {} + Vector3(float x_): x(x_) {} + float x; + }; + """.} + + type Vector3 {.importcpp: "Vector3", nodecl} = object + x: cfloat + + proc constructVector3(a: cfloat): Vector3 {.importcpp: "Vector3(@)", nodecl} + + +ImportCpp pragma +---------------- + +**Note**: `c2nim `_ can parse a large subset of C++ and knows +about the ``importcpp`` pragma pattern language. It is not necessary +to know all the details described here. + + +Similar to the `importc pragma for C +<#foreign-function-interface-importc-pragma>`_, the +``importcpp`` pragma can be used to import `C++`:idx: methods or C++ symbols +in general. The generated code then uses the C++ method calling +syntax: ``obj->method(arg)``. In combination with the ``header`` and ``emit`` +pragmas this allows *sloppy* interfacing with libraries written in C++: + +.. code-block:: Nim + # Horrible example of how to interface with a C++ engine ... ;-) + + {.link: "/usr/lib/libIrrlicht.so".} + + {.emit: """ + using namespace irr; + using namespace core; + using namespace scene; + using namespace video; + using namespace io; + using namespace gui; + """.} + + const + irr = "" + + type + IrrlichtDeviceObj {.final, header: irr, + importcpp: "IrrlichtDevice".} = object + IrrlichtDevice = ptr IrrlichtDeviceObj + + proc createDevice(): IrrlichtDevice {. + header: irr, importcpp: "createDevice(@)".} + proc run(device: IrrlichtDevice): bool {. + header: irr, importcpp: "#.run(@)".} + +The compiler needs to be told to generate C++ (command ``cpp``) for +this to work. The conditional symbol ``cpp`` is defined when the compiler +emits C++ code. + + +Namespaces +~~~~~~~~~~ + +The *sloppy interfacing* example uses ``.emit`` to produce ``using namespace`` +declarations. It is usually much better to instead refer to the imported name +via the ``namespace::identifier`` notation: + +.. code-block:: nim + type + IrrlichtDeviceObj {.final, header: irr, + importcpp: "irr::IrrlichtDevice".} = object + + +Importcpp for enums +~~~~~~~~~~~~~~~~~~~ + +When ``importcpp`` is applied to an enum type the numerical enum values are +annotated with the C++ enum type, like in this example: ``((TheCppEnum)(3))``. +(This turned out to be the simplest way to implement it.) + + +Importcpp for procs +~~~~~~~~~~~~~~~~~~~ + +Note that the ``importcpp`` variant for procs uses a somewhat cryptic pattern +language for maximum flexibility: + +- A hash ``#`` symbol is replaced by the first or next argument. +- A dot following the hash ``#.`` indicates that the call should use C++'s dot + or arrow notation. +- An at symbol ``@`` is replaced by the remaining arguments, separated by + commas. + +For example: + +.. code-block:: nim + proc cppMethod(this: CppObj, a, b, c: cint) {.importcpp: "#.CppMethod(@)".} + var x: ptr CppObj + cppMethod(x[], 1, 2, 3) + +Produces: + +.. code-block:: C + x->CppMethod(1, 2, 3) + +As a special rule to keep backwards compatibility with older versions of the +``importcpp`` pragma, if there is no special pattern +character (any of ``# ' @``) at all, C++'s +dot or arrow notation is assumed, so the above example can also be written as: + +.. code-block:: nim + proc cppMethod(this: CppObj, a, b, c: cint) {.importcpp: "CppMethod".} + +Note that the pattern language naturally also covers C++'s operator overloading +capabilities: + +.. code-block:: nim + proc vectorAddition(a, b: Vec3): Vec3 {.importcpp: "# + #".} + proc dictLookup(a: Dict, k: Key): Value {.importcpp: "#[#]".} + + +- An apostrophe ``'`` followed by an integer ``i`` in the range 0..9 + is replaced by the i'th parameter *type*. The 0th position is the result + type. This can be used to pass types to C++ function templates. Between + the ``'`` and the digit an asterisk can be used to get to the base type + of the type. (So it "takes away a star" from the type; ``T*`` becomes ``T``.) + Two stars can be used to get to the element type of the element type etc. + +For example: + +.. code-block:: nim + + type Input {.importcpp: "System::Input".} = object + proc getSubsystem*[T](): ptr T {.importcpp: "SystemManager::getSubsystem<'*0>()", nodecl.} + + let x: ptr Input = getSubsystem[Input]() + +Produces: + +.. code-block:: C + x = SystemManager::getSubsystem() + + +- ``#@`` is a special case to support a ``cnew`` operation. It is required so + that the call expression is inlined directly, without going through a + temporary location. This is only required to circumvent a limitation of the + current code generator. + +For example C++'s ``new`` operator can be "imported" like this: + +.. code-block:: nim + proc cnew*[T](x: T): ptr T {.importcpp: "(new '*0#@)", nodecl.} + + # constructor of 'Foo': + proc constructFoo(a, b: cint): Foo {.importcpp: "Foo(@)".} + + let x = cnew constructFoo(3, 4) + +Produces: + +.. code-block:: C + x = new Foo(3, 4) + +However, depending on the use case ``new Foo`` can also be wrapped like this +instead: + +.. code-block:: nim + proc newFoo(a, b: cint): ptr Foo {.importcpp: "new Foo(@)".} + + let x = newFoo(3, 4) + + +Wrapping constructors +~~~~~~~~~~~~~~~~~~~~~ + +Sometimes a C++ class has a private copy constructor and so code like +``Class c = Class(1,2);`` must not be generated but instead ``Class c(1,2);``. +For this purpose the Nim proc that wraps a C++ constructor needs to be +annotated with the `constructor`:idx: pragma. This pragma also helps to generate +faster C++ code since construction then doesn't invoke the copy constructor: + +.. code-block:: nim + # a better constructor of 'Foo': + proc constructFoo(a, b: cint): Foo {.importcpp: "Foo(@)", constructor.} + + +Wrapping destructors +~~~~~~~~~~~~~~~~~~~~ + +Since Nim generates C++ directly, any destructor is called implicitly by the +C++ compiler at the scope exits. This means that often one can get away with +not wrapping the destructor at all! However when it needs to be invoked +explicitly, it needs to be wrapped. But the pattern language already provides +everything that is required for that: + +.. code-block:: nim + proc destroyFoo(this: var Foo) {.importcpp: "#.~Foo()".} + + +Importcpp for objects +~~~~~~~~~~~~~~~~~~~~~ + +Generic ``importcpp``'ed objects are mapped to C++ templates. This means that +you can import C++'s templates rather easily without the need for a pattern +language for object types: + +.. code-block:: nim + type + StdMap {.importcpp: "std::map", header: "".} [K, V] = object + proc `[]=`[K, V](this: var StdMap[K, V]; key: K; val: V) {. + importcpp: "#[#] = #", header: "".} + + var x: StdMap[cint, cdouble] + x[6] = 91.4 + + +Produces: + +.. code-block:: C + std::map x; + x[6] = 91.4; + + +- If more precise control is needed, the apostrophe ``'`` can be used in the + supplied pattern to denote the concrete type parameters of the generic type. + See the usage of the apostrophe operator in proc patterns for more details. + +.. code-block:: nim + + type + VectorIterator {.importcpp: "std::vector<'0>::iterator".} [T] = object + + var x: VectorIterator[cint] + + +Produces: + +.. code-block:: C + + std::vector::iterator x; + + +ImportObjC pragma +----------------- +Similar to the `importc pragma for C +<#foreign-function-interface-importc-pragma>`_, the ``importobjc`` pragma can +be used to import `Objective C`:idx: methods. The generated code then uses the +Objective C method calling syntax: ``[obj method param1: arg]``. +In addition with the ``header`` and ``emit`` pragmas this +allows *sloppy* interfacing with libraries written in Objective C: + +.. code-block:: Nim + # horrible example of how to interface with GNUStep ... + + {.passL: "-lobjc".} + {.emit: """ + #include + @interface Greeter:Object + { + } + + - (void)greet:(long)x y:(long)dummy; + @end + + #include + @implementation Greeter + + - (void)greet:(long)x y:(long)dummy + { + printf("Hello, World!\n"); + } + @end + + #include + """.} + + type + Id {.importc: "id", header: "", final.} = distinct int + + proc newGreeter: Id {.importobjc: "Greeter new", nodecl.} + proc greet(self: Id, x, y: int) {.importobjc: "greet", nodecl.} + proc free(self: Id) {.importobjc: "free", nodecl.} + + var g = newGreeter() + g.greet(12, 34) + g.free() + +The compiler needs to be told to generate Objective C (command ``objc``) for +this to work. The conditional symbol ``objc`` is defined when the compiler +emits Objective C code. + + +CodegenDecl pragma +------------------ + +The ``codegenDecl`` pragma can be used to directly influence Nim's code +generator. It receives a format string that determines how the variable +or proc is declared in the generated code. + +For variables $1 in the format string represents the type of the variable +and $2 is the name of the variable. + +The following Nim code: + +.. code-block:: nim + var + a {.codegenDecl: "$# progmem $#".}: int + +will generate this C code: + +.. code-block:: c + int progmem a + +For procedures $1 is the return type of the procedure, $2 is the name of +the procedure and $3 is the parameter list. + +The following nim code: + +.. code-block:: nim + proc myinterrupt() {.codegenDecl: "__interrupt $# $#$#".} = + echo "realistic interrupt handler" + +will generate this code: + +.. code-block:: c + __interrupt void myinterrupt() + + +InjectStmt pragma +----------------- + +The ``injectStmt`` pragma can be used to inject a statement before every +other statement in the current module. It is only supposed to be used for +debugging: + +.. code-block:: nim + {.injectStmt: gcInvariants().} + + # ... complex code here that produces crashes ... + +compile time define pragmas +--------------------------- + +The pragmas listed here can be used to optionally accept values from +the -d/--define option at compile time. + +The implementation currently provides the following possible options (various +others may be added later). + +================= ============================================ +pragma description +================= ============================================ +`intdefine`:idx: Reads in a build-time define as an integer +`strdefine`:idx: Reads in a build-time define as a string +================= ============================================ + +.. code-block:: nim + const FooBar {.intdefine.}: int = 5 + echo FooBar + +.. code-block:: bash + nim c -d:FooBar=42 foobar.c + +In the above example, providing the -d flag causes the symbol +``FooBar`` to be overwritten at compile time, printing out 42. If the +``-d:FooBar=42`` were to be omitted, the default value of 5 would be +used. + + +Custom annotations +------------------ +It is possible to define custom typed pragmas. Custom pragmas do not effect +code generation directly, but their presence can be detected by macros. +Custom pragmas are defined using templates annotated with pragma ``pragma``: + +.. code-block:: nim + template dbTable(name: string, table_space: string = nil) {.pragma.} + template dbKey(name: string = nil, primary_key: bool = false) {.pragma.} + template dbForeignKey(t: typedesc) {.pragma.} + template dbIgnore {.pragma.} + + +Consider stylized example of possible Object Relation Mapping (ORM) implementation: + +.. code-block:: nim + const tblspace {.strdefine.} = "dev" # switch for dev, test and prod environments + + type + User {.dbTable("users", tblspace).} = object + id {.dbKey(primary_key = true).}: int + name {.dbKey"full_name".}: string + is_cached {.dbIgnore.}: bool + age: int + + UserProfile {.dbTable("profiles", tblspace).} = object + id {.dbKey(primary_key = true).}: int + user_id {.dbForeignKey: User.}: int + read_access: bool + write_access: bool + admin_acess: bool + +In this example custom pragmas are used to describe how Nim objects are +mapped to the schema of the relational database. Custom pragmas can have +zero or more arguments. In order to pass multiple arguments use one of +template call syntaxes. All arguments are typed and follow standard +overload resolution rules for templates. Therefore, it is possible to have +default values for arguments, pass by name, varargs, etc. + +Custom pragmas can be used in all locations where ordinary pragmas can be +specified. It is possible to annotate procs, templates, type and variable +definitions, statements, etc. + +Macros module includes helpers which can be used to simplify custom pragma +access `hasCustomPragma`, `getCustomPragmaVal`. Please consult macros module +documentation for details. These macros are no magic, they don't do anything +you cannot do yourself by walking AST object representation. + +More examples with custom pragmas: + - Better serialization/deserialization control: + + .. code-block:: nim + type MyObj = object + a {.dontSerialize.}: int + b {.defaultDeserialize: 5.}: int + c {.serializationKey: "_c".}: string + + - Adopting type for gui inspector in a game engine: + + .. code-block:: nim + type MyComponent = object + position {.editable, animatable.}: Vector3 + alpha {.editRange: [0.0..1.0], animatable.}: float32 + + + + +Foreign function interface +========================== + +Nim's `FFI`:idx: (foreign function interface) is extensive and only the +parts that scale to other future backends (like the LLVM/JavaScript backends) +are documented here. + + +Importc pragma +-------------- +The ``importc`` pragma provides a means to import a proc or a variable +from C. The optional argument is a string containing the C identifier. If +the argument is missing, the C name is the Nim identifier *exactly as +spelled*: + +.. code-block:: + proc printf(formatstr: cstring) {.header: "", importc: "printf", varargs.} + +Note that this pragma is somewhat of a misnomer: Other backends do provide +the same feature under the same name. Also, if one is interfacing with C++ +the `ImportCpp pragma `_ and +interfacing with Objective-C the `ImportObjC pragma +`_ can be used. + +The string literal passed to ``importc`` can be a format string: + +.. code-block:: Nim + proc p(s: cstring) {.importc: "prefix$1".} + +In the example the external name of ``p`` is set to ``prefixp``. Only ``$1`` +is available and a literal dollar sign must be written as ``$$``. + + +Exportc pragma +-------------- +The ``exportc`` pragma provides a means to export a type, a variable, or a +procedure to C. Enums and constants can't be exported. The optional argument +is a string containing the C identifier. If the argument is missing, the C +name is the Nim identifier *exactly as spelled*: + +.. code-block:: Nim + proc callme(formatstr: cstring) {.exportc: "callMe", varargs.} + +Note that this pragma is somewhat of a misnomer: Other backends do provide +the same feature under the same name. + +The string literal passed to ``exportc`` can be a format string: + +.. code-block:: Nim + proc p(s: string) {.exportc: "prefix$1".} = + echo s + +In the example the external name of ``p`` is set to ``prefixp``. Only ``$1`` +is available and a literal dollar sign must be written as ``$$``. + + + +Extern pragma +------------- +Like ``exportc`` or ``importc``, the ``extern`` pragma affects name +mangling. The string literal passed to ``extern`` can be a format string: + +.. code-block:: Nim + proc p(s: string) {.extern: "prefix$1".} = + echo s + +In the example the external name of ``p`` is set to ``prefixp``. Only ``$1`` +is available and a literal dollar sign must be written as ``$$``. + + + +Bycopy pragma +------------- + +The ``bycopy`` pragma can be applied to an object or tuple type and +instructs the compiler to pass the type by value to procs: + +.. code-block:: nim + type + Vector {.bycopy, pure.} = object + x, y, z: float + + +Byref pragma +------------ + +The ``byref`` pragma can be applied to an object or tuple type and instructs +the compiler to pass the type by reference (hidden pointer) to procs. + + +Varargs pragma +-------------- +The ``varargs`` pragma can be applied to procedures only (and procedure +types). It tells Nim that the proc can take a variable number of parameters +after the last specified parameter. Nim string values will be converted to C +strings automatically: + +.. code-block:: Nim + proc printf(formatstr: cstring) {.nodecl, varargs.} + + printf("hallo %s", "world") # "world" will be passed as C string + + +Union pragma +------------ +The ``union`` pragma can be applied to any ``object`` type. It means all +of the object's fields are overlaid in memory. This produces a ``union`` +instead of a ``struct`` in the generated C/C++ code. The object declaration +then must not use inheritance or any GC'ed memory but this is currently not +checked. + +**Future directions**: GC'ed memory should be allowed in unions and the GC +should scan unions conservatively. + +Packed pragma +------------- +The ``packed`` pragma can be applied to any ``object`` type. It ensures +that the fields of an object are packed back-to-back in memory. It is useful +to store packets or messages from/to network or hardware drivers, and for +interoperability with C. Combining packed pragma with inheritance is not +defined, and it should not be used with GC'ed memory (ref's). + +**Future directions**: Using GC'ed memory in packed pragma will result in +compile-time error. Usage with inheritance should be defined and documented. + +Unchecked pragma +---------------- +The ``unchecked`` pragma can be used to mark a named array as ``unchecked`` +meaning its bounds are not checked. This is often useful to +implement customized flexibly sized arrays. Additionally an unchecked array is +translated into a C array of undetermined size: + +.. code-block:: nim + type + ArrayPart{.unchecked.} = array[0, int] + MySeq = object + len, cap: int + data: ArrayPart + +Produces roughly this C code: + +.. code-block:: C + typedef struct { + NI len; + NI cap; + NI data[]; + } MySeq; + +The base type of the unchecked array may not contain any GC'ed memory but this +is currently not checked. + +**Future directions**: GC'ed memory should be allowed in unchecked arrays and +there should be an explicit annotation of how the GC is to determine the +runtime size of the array. + + +Dynlib pragma for import +------------------------ +With the ``dynlib`` pragma a procedure or a variable can be imported from +a dynamic library (``.dll`` files for Windows, ``lib*.so`` files for UNIX). +The non-optional argument has to be the name of the dynamic library: + +.. code-block:: Nim + proc gtk_image_new(): PGtkWidget + {.cdecl, dynlib: "libgtk-x11-2.0.so", importc.} + +In general, importing a dynamic library does not require any special linker +options or linking with import libraries. This also implies that no *devel* +packages need to be installed. + +The ``dynlib`` import mechanism supports a versioning scheme: + +.. code-block:: nim + proc Tcl_Eval(interp: pTcl_Interp, script: cstring): int {.cdecl, + importc, dynlib: "libtcl(|8.5|8.4|8.3).so.(1|0)".} + +At runtime the dynamic library is searched for (in this order):: + + libtcl.so.1 + libtcl.so.0 + libtcl8.5.so.1 + libtcl8.5.so.0 + libtcl8.4.so.1 + libtcl8.4.so.0 + libtcl8.3.so.1 + libtcl8.3.so.0 + +The ``dynlib`` pragma supports not only constant strings as argument but also +string expressions in general: + +.. code-block:: nim + import os + + proc getDllName: string = + result = "mylib.dll" + if existsFile(result): return + result = "mylib2.dll" + if existsFile(result): return + quit("could not load dynamic library") + + proc myImport(s: cstring) {.cdecl, importc, dynlib: getDllName().} + +**Note**: Patterns like ``libtcl(|8.5|8.4).so`` are only supported in constant +strings, because they are precompiled. + +**Note**: Passing variables to the ``dynlib`` pragma will fail at runtime +because of order of initialization problems. + +**Note**: A ``dynlib`` import can be overridden with +the ``--dynlibOverride:name`` command line option. The Compiler User Guide +contains further information. + + +Dynlib pragma for export +------------------------ + +With the ``dynlib`` pragma a procedure can also be exported to +a dynamic library. The pragma then has no argument and has to be used in +conjunction with the ``exportc`` pragma: + +.. code-block:: Nim + proc exportme(): int {.cdecl, exportc, dynlib.} + +This is only useful if the program is compiled as a dynamic library via the +``--app:lib`` command line option. This pragma only has an effect for the code +generation on the Windows target, so when this pragma is forgotten and the dynamic +library is only tested on Mac and/or Linux, there won't be an error. On Windows +this pragma adds ``__declspec(dllexport)`` to the function declaration. + + + +Threads +======= + +To enable thread support the ``--threads:on`` command line switch needs to +be used. The ``system`` module then contains several threading primitives. +See the `threads `_ and `channels `_ modules +for the low level thread API. There are also high level parallelism constructs +available. See `spawn <#parallel-spawn>`_ for further details. + +Nim's memory model for threads is quite different than that of other common +programming languages (C, Pascal, Java): Each thread has its own (garbage +collected) heap and sharing of memory is restricted to global variables. This +helps to prevent race conditions. GC efficiency is improved quite a lot, +because the GC never has to stop other threads and see what they reference. +Memory allocation requires no lock at all! This design easily scales to massive +multicore processors that are becoming the norm. + + +Thread pragma +------------- + +A proc that is executed as a new thread of execution should be marked by the +``thread`` pragma for reasons of readability. The compiler checks for +violations of the `no heap sharing restriction`:idx:\: This restriction implies +that it is invalid to construct a data structure that consists of memory +allocated from different (thread local) heaps. + +A thread proc is passed to ``createThread`` or ``spawn`` and invoked +indirectly; so the ``thread`` pragma implies ``procvar``. + + +GC safety +--------- + +We call a proc ``p`` `GC safe`:idx: when it doesn't access any global variable +that contains GC'ed memory (``string``, ``seq``, ``ref`` or a closure) either +directly or indirectly through a call to a GC unsafe proc. + +The `gcsafe`:idx: annotation can be used to mark a proc to be gcsafe, +otherwise this property is inferred by the compiler. Note that ``noSideEffect`` +implies ``gcsafe``. The only way to create a thread is via ``spawn`` or +``createThread``. ``spawn`` is usually the preferable method. Either way +the invoked proc must not use ``var`` parameters nor must any of its parameters +contain a ``ref`` or ``closure`` type. This enforces +the *no heap sharing restriction*. + +Routines that are imported from C are always assumed to be ``gcsafe``. +To disable the GC-safety checking the ``--threadAnalysis:off`` command line +switch can be used. This is a temporary workaround to ease the porting effort +from old code to the new threading model. + +To override the compiler's gcsafety analysis a ``{.gcsafe.}`` pragma block can +be used: + +.. code-block:: nim + + var + someGlobal: string = "some string here" + perThread {.threadvar.}: string + + proc setPerThread() = + {.gcsafe.}: + deepCopy(perThread, someGlobal) + + +Future directions: + +- A shared GC'ed heap might be provided. + + +Threadvar pragma +---------------- + +A global variable can be marked with the ``threadvar`` pragma; it is +a `thread-local`:idx: variable then: + +.. code-block:: nim + var checkpoints* {.threadvar.}: seq[string] + +Due to implementation restrictions thread local variables cannot be +initialized within the ``var`` section. (Every thread local variable needs to +be replicated at thread creation.) + + +Threads and exceptions +---------------------- + +The interaction between threads and exceptions is simple: A *handled* exception +in one thread cannot affect any other thread. However, an *unhandled* exception +in one thread terminates the whole *process*! + + + +Parallel & Spawn +================ + +Nim has two flavors of parallelism: +1) `Structured`:idx: parallelism via the ``parallel`` statement. +2) `Unstructured`:idx: parallelism via the standalone ``spawn`` statement. + +Nim has a builtin thread pool that can be used for CPU intensive tasks. For +IO intensive tasks the ``async`` and ``await`` features should be +used instead. Both parallel and spawn need the `threadpool `_ +module to work. + +Somewhat confusingly, ``spawn`` is also used in the ``parallel`` statement +with slightly different semantics. ``spawn`` always takes a call expression of +the form ``f(a, ...)``. Let ``T`` be ``f``'s return type. If ``T`` is ``void`` +then ``spawn``'s return type is also ``void`` otherwise it is ``FlowVar[T]``. + +Within a ``parallel`` section sometimes the ``FlowVar[T]`` is eliminated +to ``T``. This happens when ``T`` does not contain any GC'ed memory. +The compiler can ensure the location in ``location = spawn f(...)`` is not +read prematurely within a ``parallel`` section and so there is no need for +the overhead of an indirection via ``FlowVar[T]`` to ensure correctness. + +**Note**: Currently exceptions are not propagated between ``spawn``'ed tasks! + + +Spawn statement +--------------- + +`spawn`:idx: can be used to pass a task to the thread pool: + +.. code-block:: nim + import threadpool + + proc processLine(line: string) = + discard "do some heavy lifting here" + + for x in lines("myinput.txt"): + spawn processLine(x) + sync() + +For reasons of type safety and implementation simplicity the expression +that ``spawn`` takes is restricted: + +* It must be a call expression ``f(a, ...)``. +* ``f`` must be ``gcsafe``. +* ``f`` must not have the calling convention ``closure``. +* ``f``'s parameters may not be of type ``var``. + This means one has to use raw ``ptr``'s for data passing reminding the + programmer to be careful. +* ``ref`` parameters are deeply copied which is a subtle semantic change and + can cause performance problems but ensures memory safety. This deep copy + is performed via ``system.deepCopy`` and so can be overridden. +* For *safe* data exchange between ``f`` and the caller a global ``TChannel`` + needs to be used. However, since spawn can return a result, often no further + communication is required. + + +``spawn`` executes the passed expression on the thread pool and returns +a `data flow variable`:idx: ``FlowVar[T]`` that can be read from. The reading +with the ``^`` operator is **blocking**. However, one can use ``awaitAny`` to +wait on multiple flow variables at the same time: + +.. code-block:: nim + import threadpool, ... + + # wait until 2 out of 3 servers received the update: + proc main = + var responses = newSeq[FlowVarBase](3) + for i in 0..2: + responses[i] = spawn tellServer(Update, "key", "value") + var index = awaitAny(responses) + assert index >= 0 + responses.del(index) + discard awaitAny(responses) + +Data flow variables ensure that no data races +are possible. Due to technical limitations not every type ``T`` is possible in +a data flow variable: ``T`` has to be of the type ``ref``, ``string``, ``seq`` +or of a type that doesn't contain a type that is garbage collected. This +restriction is not hard to work-around in practice. + + + +Parallel statement +------------------ + +Example: + +.. code-block:: nim + # Compute PI in an inefficient way + import strutils, math, threadpool + + proc term(k: float): float = 4 * math.pow(-1, k) / (2*k + 1) + + proc pi(n: int): float = + var ch = newSeq[float](n+1) + parallel: + for k in 0..ch.high: + ch[k] = spawn term(float(k)) + for k in 0..ch.high: + result += ch[k] + + echo formatFloat(pi(5000)) + + +The parallel statement is the preferred mechanism to introduce parallelism +in a Nim program. A subset of the Nim language is valid within a +``parallel`` section. This subset is checked to be free of data races at +compile time. A sophisticated `disjoint checker`:idx: ensures that no data +races are possible even though shared memory is extensively supported! + +The subset is in fact the full language with the following +restrictions / changes: + +* ``spawn`` within a ``parallel`` section has special semantics. +* Every location of the form ``a[i]`` and ``a[i..j]`` and ``dest`` where + ``dest`` is part of the pattern ``dest = spawn f(...)`` has to be + provably disjoint. This is called the *disjoint check*. +* Every other complex location ``loc`` that is used in a spawned + proc (``spawn f(loc)``) has to be immutable for the duration of + the ``parallel`` section. This is called the *immutability check*. Currently + it is not specified what exactly "complex location" means. We need to make + this an optimization! +* Every array access has to be provably within bounds. This is called + the *bounds check*. +* Slices are optimized so that no copy is performed. This optimization is not + yet performed for ordinary slices outside of a ``parallel`` section. + + +Guards and locks +================ + +Apart from ``spawn`` and ``parallel`` Nim also provides all the common low level +concurrency mechanisms like locks, atomic intrinsics or condition variables. + +Nim significantly improves on the safety of these features via additional +pragmas: + +1) A `guard`:idx: annotation is introduced to prevent data races. +2) Every access of a guarded memory location needs to happen in an + appropriate `locks`:idx: statement. +3) Locks and routines can be annotated with `lock levels`:idx: to prevent + deadlocks at compile time. + + +Guards and the locks section +---------------------------- + +Protecting global variables +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Object fields and global variables can be annotated via a ``guard`` pragma: + +.. code-block:: nim + var glock: TLock + var gdata {.guard: glock.}: int + +The compiler then ensures that every access of ``gdata`` is within a ``locks`` +section: + +.. code-block:: nim + proc invalid = + # invalid: unguarded access: + echo gdata + + proc valid = + # valid access: + {.locks: [glock].}: + echo gdata + +Top level accesses to ``gdata`` are always allowed so that it can be initialized +conveniently. It is *assumed* (but not enforced) that every top level statement +is executed before any concurrent action happens. + +The ``locks`` section deliberately looks ugly because it has no runtime +semantics and should not be used directly! It should only be used in templates +that also implement some form of locking at runtime: + +.. code-block:: nim + template lock(a: TLock; body: untyped) = + pthread_mutex_lock(a) + {.locks: [a].}: + try: + body + finally: + pthread_mutex_unlock(a) + + +The guard does not need to be of any particular type. It is flexible enough to +model low level lockfree mechanisms: + +.. code-block:: nim + var dummyLock {.compileTime.}: int + var atomicCounter {.guard: dummyLock.}: int + + template atomicRead(x): untyped = + {.locks: [dummyLock].}: + memoryReadBarrier() + x + + echo atomicRead(atomicCounter) + + +The ``locks`` pragma takes a list of lock expressions ``locks: [a, b, ...]`` +in order to support *multi lock* statements. Why these are essential is +explained in the `lock levels <#guards-and-locks-lock-levels>`_ section. + + +Protecting general locations +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The ``guard`` annotation can also be used to protect fields within an object. +The guard then needs to be another field within the same object or a +global variable. + +Since objects can reside on the heap or on the stack this greatly enhances the +expressivity of the language: + +.. code-block:: nim + type + ProtectedCounter = object + v {.guard: L.}: int + L: TLock + + proc incCounters(counters: var openArray[ProtectedCounter]) = + for i in 0..counters.high: + lock counters[i].L: + inc counters[i].v + +The access to field ``x.v`` is allowed since its guard ``x.L`` is active. +After template expansion, this amounts to: + +.. code-block:: nim + proc incCounters(counters: var openArray[ProtectedCounter]) = + for i in 0..counters.high: + pthread_mutex_lock(counters[i].L) + {.locks: [counters[i].L].}: + try: + inc counters[i].v + finally: + pthread_mutex_unlock(counters[i].L) + +There is an analysis that checks that ``counters[i].L`` is the lock that +corresponds to the protected location ``counters[i].v``. This analysis is called +`path analysis`:idx: because it deals with paths to locations +like ``obj.field[i].fieldB[j]``. + +The path analysis is **currently unsound**, but that doesn't make it useless. +Two paths are considered equivalent if they are syntactically the same. + +This means the following compiles (for now) even though it really should not: + +.. code-block:: nim + {.locks: [a[i].L].}: + inc i + access a[i].v + + + +Lock levels +----------- + +Lock levels are used to enforce a global locking order in order to prevent +deadlocks at compile-time. A lock level is an constant integer in the range +0..1_000. Lock level 0 means that no lock is acquired at all. + +If a section of code holds a lock of level ``M`` than it can also acquire any +lock of level ``N < M``. Another lock of level ``M`` cannot be acquired. Locks +of the same level can only be acquired *at the same time* within a +single ``locks`` section: + +.. code-block:: nim + var a, b: TLock[2] + var x: TLock[1] + # invalid locking order: TLock[1] cannot be acquired before TLock[2]: + {.locks: [x].}: + {.locks: [a].}: + ... + # valid locking order: TLock[2] acquired before TLock[1]: + {.locks: [a].}: + {.locks: [x].}: + ... + + # invalid locking order: TLock[2] acquired before TLock[2]: + {.locks: [a].}: + {.locks: [b].}: + ... + + # valid locking order, locks of the same level acquired at the same time: + {.locks: [a, b].}: + ... + + +Here is how a typical multilock statement can be implemented in Nim. Note how +the runtime check is required to ensure a global ordering for two locks ``a`` +and ``b`` of the same lock level: + +.. code-block:: nim + template multilock(a, b: ptr TLock; body: untyped) = + if cast[ByteAddress](a) < cast[ByteAddress](b): + pthread_mutex_lock(a) + pthread_mutex_lock(b) + else: + pthread_mutex_lock(b) + pthread_mutex_lock(a) + {.locks: [a, b].}: + try: + body + finally: + pthread_mutex_unlock(a) + pthread_mutex_unlock(b) + + +Whole routines can also be annotated with a ``locks`` pragma that takes a lock +level. This then means that the routine may acquire locks of up to this level. +This is essential so that procs can be called within a ``locks`` section: + +.. code-block:: nim + proc p() {.locks: 3.} = discard + + var a: TLock[4] + {.locks: [a].}: + # p's locklevel (3) is strictly less than a's (4) so the call is allowed: + p() + + +As usual ``locks`` is an inferred effect and there is a subtype +relation: ``proc () {.locks: N.}`` is a subtype of ``proc () {.locks: M.}`` +iff (M <= N). + +The ``locks`` pragma can also take the special value ``"unknown"``. This +is useful in the context of dynamic method dispatching. In the following +example, the compiler can infer a lock level of 0 for the ``base`` case. +However, one of the overloaded methods calls a procvar which is +potentially locking. Thus, the lock level of calling ``g.testMethod`` +cannot be inferred statically, leading to compiler warnings. By using +``{.locks: "unknown".}``, the base method can be marked explicitly as +having unknown lock level as well: + +.. code-block:: nim + type SomeBase* = ref object of RootObj + type SomeDerived* = ref object of SomeBase + memberProc*: proc () + + method testMethod(g: SomeBase) {.base, locks: "unknown".} = discard + method testMethod(g: SomeDerived) = + if g.memberProc != nil: + g.memberProc() + + +Taint mode +========== + +The Nim compiler and most parts of the standard library support +a taint mode. Input strings are declared with the `TaintedString`:idx: +string type declared in the ``system`` module. + +If the taint mode is turned on (via the ``--taintMode:on`` command line +option) it is a distinct string type which helps to detect input +validation errors: + +.. code-block:: nim + echo "your name: " + var name: TaintedString = stdin.readline + # it is safe here to output the name without any input validation, so + # we simply convert `name` to string to make the compiler happy: + echo "hi, ", name.string + +If the taint mode is turned off, ``TaintedString`` is simply an alias for +``string``. + + diff --git a/doc/manual/about.txt b/doc/manual/about.txt deleted file mode 100644 index 58e3baa85e..0000000000 --- a/doc/manual/about.txt +++ /dev/null @@ -1,37 +0,0 @@ -About this document -=================== - -**Note**: This document is a draft!

Only ``$1`` -is available and a literal dollar sign must be written as ``$$``. - - - -Bycopy pragma -------------- - -The ``bycopy`` pragma can be applied to an object or tuple type and -instructs the compiler to pass the type by value to procs: - -.. code-block:: nim - type - Vector {.bycopy, pure.} = object - x, y, z: float - - -Byref pragma ------------- - -The ``byref`` pragma can be applied to an object or tuple type and instructs -the compiler to pass the type by reference (hidden pointer) to procs. - - -Varargs pragma --------------- -The ``varargs`` pragma can be applied to procedures only (and procedure -types). It tells Nim that the proc can take a variable number of parameters -after the last specified parameter. Nim string values will be converted to C -strings automatically: - -.. code-block:: Nim - proc printf(formatstr: cstring) {.nodecl, varargs.} - - printf("hallo %s", "world") # "world" will be passed as C string - - -Union pragma ------------- -The ``union`` pragma can be applied to any ``object`` type. It means all -of the object's fields are overlaid in memory. This produces a ``union`` -instead of a ``struct`` in the generated C/C++ code. The object declaration -then must not use inheritance or any GC'ed memory but this is currently not -checked. - -**Future directions**: GC'ed memory should be allowed in unions and the GC -should scan unions conservatively. - -Packed pragma -------------- -The ``packed`` pragma can be applied to any ``object`` type. It ensures -that the fields of an object are packed back-to-back in memory. It is useful -to store packets or messages from/to network or hardware drivers, and for -interoperability with C. Combining packed pragma with inheritance is not -defined, and it should not be used with GC'ed memory (ref's). - -**Future directions**: Using GC'ed memory in packed pragma will result in -compile-time error. Usage with inheritance should be defined and documented. - -Unchecked pragma ----------------- -The ``unchecked`` pragma can be used to mark a named array as ``unchecked`` -meaning its bounds are not checked. This is often useful to -implement customized flexibly sized arrays. Additionally an unchecked array is -translated into a C array of undetermined size: - -.. code-block:: nim - type - ArrayPart{.unchecked.} = array[0, int] - MySeq = object - len, cap: int - data: ArrayPart - -Produces roughly this C code: - -.. code-block:: C - typedef struct { - NI len; - NI cap; - NI data[]; - } MySeq; - -The base type of the unchecked array may not contain any GC'ed memory but this -is currently not checked. - -**Future directions**: GC'ed memory should be allowed in unchecked arrays and -there should be an explicit annotation of how the GC is to determine the -runtime size of the array. - - -Dynlib pragma for import ------------------------- -With the ``dynlib`` pragma a procedure or a variable can be imported from -a dynamic library (``.dll`` files for Windows, ``lib*.so`` files for UNIX). -The non-optional argument has to be the name of the dynamic library: - -.. code-block:: Nim - proc gtk_image_new(): PGtkWidget - {.cdecl, dynlib: "libgtk-x11-2.0.so", importc.} - -In general, importing a dynamic library does not require any special linker -options or linking with import libraries.

The Compiler User Guide -contains further information. - - -Dynlib pragma for export ------------------------- - -With the ``dynlib`` pragma a procedure can also be exported to -a dynamic library. The pragma then has no argument and has to be used in -conjunction with the ``exportc`` pragma: - -.. code-block:: Nim - proc exportme(): int {.cdecl, exportc, dynlib.} - -This is only useful if the program is compiled as a dynamic library via the -``--app:lib`` command line option. This pragma only has an effect for the code -generation on the Windows target, so when this pragma is forgotten and the dynamic -library is only tested on Mac and/or Linux, there won't be an error. On Windows -this pragma adds ``__declspec(dllexport)`` to the function declaration. - diff --git a/doc/manual/generics.txt b/doc/manual/generics.txt deleted file mode 100644 index 01f76b5916..0000000000 --- a/doc/manual/generics.txt +++ /dev/null @@ -1,715 +0,0 @@ -Generics -======== - -Generics are Nim's means to parametrize procs, iterators or types with -`type parameters`:idx:.

Such -type classes are called `bind many`:idx: types. - -Procs written with the implicitly generic style will often need to refer to the -type parameters of the matched generic type. They can be easily accessed using -the dot syntax: - -.. code-block:: nim - type Matrix[T, Rows, Columns] = object - ... - - proc `[]`(m: Matrix, row, col: int): Matrix.T = - m.data[col * high(Matrix.Columns) + row] - -Alternatively, the `type` operator can be used over the proc params for similar -effect when anonymous or distinct type classes are used. - -When a generic type is instantiated with a type class instead of a concrete -type, this results in another more specific type class: - -.. code-block:: nim - seq[ref object] # Any sequence storing references to any object type - - type T1 = auto - proc foo(s: seq[T1], e: T1) - # seq[T1] is the same as just `seq`, but T1 will be allowed to bind - # to a single type, while the signature is being matched - - Matrix[Ordinal] # Any Matrix instantiation using integer values - -As seen in the previous example, in such instantiations, it's not necessary to -supply all type parameters of the generic type, because any missing ones will -be inferred to have the equivalent of the `any` type class and thus they will -match anything without discrimination. - - -Concepts --------- - -**Note**: Concepts are still in development. - -Concepts, also known as "user-defined type classes", are used to specify an -arbitrary set of requirements that the matched type must satisfy. - -Concepts are written in the following form: - -.. code-block:: nim - type - Comparable = concept x, y - (x < y) is bool - - Stack[T] = concept s, var v - s.pop() is T - v.push(T) - - s.len is Ordinal - - for value in s: - value is T - -The concept is a match if: - -a) all of the expressions within the body can be compiled for the tested type -b) all statically evaluable boolean expressions in the body must be true - -The identifiers following the ``concept`` keyword represent instances of the -currently matched type. You can apply any of the standard type modifiers such -as ``var``, ``ref``, ``ptr`` and ``static`` to denote a more specific type of -instance. You can also apply the `type` modifier to create a named instance of -the type itself: - -.. code-block:: nim - type - MyConcept = concept x, var v, ref r, ptr p, static s, type T - ... - -Within the concept body, types can appear in positions where ordinary values -and parameters are expected. This provides a more convenient way to check for -the presence of callable symbols with specific signatures: - -.. code-block:: nim - type - OutputStream = concept var s - s.write(string) - -In order to check for symbols accepting ``typedesc`` params, you must prefix -the type with an explicit ``type`` modifier. The named instance of the type, -following the ``concept`` keyword is also considered an explicit ``typedesc`` -value that will be matched only as a type. - -.. code-block:: nim - type - # Let's imagine a user-defined casting framework with operators - # such as `val.to(string)` and `val.to(JSonValue)`. We can test - # for these with the following concept: - MyCastables = concept x - x.to(type string) - x.to(type JSonValue) - - # Let's define a couple of concepts, known from Algebra: - AdditiveMonoid* = concept x, y, type T - x + y is T - T.zero is T # require a proc such as `int.zero` or 'Position.zero' - - AdditiveGroup* = concept x, y, type T - x is AdditiveMonoid - -x is T - x - y is T - -Please note that the ``is`` operator allows one to easily verify the precise -type signatures of the required operations, but since type inference and -default parameters are still applied in the concept body, it's also possible -to describe usage protocols that do not reveal implementation details. - -Much like generics, concepts are instantiated exactly once for each tested type -and any static code included within the body is executed only once. - - -Concept diagnostics -------------------- - -By default, the compiler will report the matching errors in concepts only when -no other overload can be selected and a normal compilation error is produced. -When you need to understand why the compiler is not matching a particular -concept and, as a result, a wrong overload is selected, you can apply the -``explain`` pragma to either the concept body or a particular call-site. - -.. code-block:: nim - type - MyConcept {.explain.} = concept ... - - overloadedProc(x, y, z) {.explain.} - -This will provide Hints in the compiler output either every time the concept is -not matched or only on the particular call-site. - - -Generic concepts and type binding rules ---------------------------------------- - -The concept types can be parametric just like the regular generic types: - -.. code-block:: nim - ### matrixalgo.nim - - import typetraits - - type - AnyMatrix*[R, C: static[int]; T] = concept m, var mvar, type M - M.ValueType is T - M.Rows == R - M.Cols == C - - m[int, int] is T - mvar[int, int] = T - - type TransposedType = stripGenericParams(M)[C, R, T] - - AnySquareMatrix*[N: static[int], T] = AnyMatrix[N, N, T] - - AnyTransform3D* = AnyMatrix[4, 4, float] - - proc transposed*(m: AnyMatrix): m.TransposedType = - for r in 0 ..< m.R: - for c in 0 ..< m.C: - result[r, c] = m[c, r] - - proc determinant*(m: AnySquareMatrix): int = - ... - - proc setPerspectiveProjection*(m: AnyTransform3D) = - ... - - -------------- - ### matrix.nim - - type - Matrix*[M, N: static[int]; T] = object - data: array[M*N, T] - - proc `[]`*(M: Matrix; m, n: int): M.T = - M.data[m * M.N + n] - - proc `[]=`*(M: var Matrix; m, n: int; v: M.T) = - M.data[m * M.N + n] = v - - # Adapt the Matrix type to the concept's requirements - template Rows*(M: type Matrix): expr = M.M - template Cols*(M: type Matrix): expr = M.N - template ValueType*(M: type Matrix): typedesc = M.T - - ------------- - ### usage.nim - - import matrix, matrixalgo - - var - m: Matrix[3, 3, int] - projectionMatrix: Matrix[4, 4, float] - - echo m.transposed.determinant - setPerspectiveProjection projectionMatrix - -When the concept type is matched against a concrete type, the unbound type -parameters are inferred from the body of the concept in a way that closely -resembles the way generic parameters of callable symbols are inferred on -call sites. - -Unbound types can appear both as params to calls such as `s.push(T)` and -on the right-hand side of the ``is`` operator in cases such as `x.pop is T` -and `x.data is seq[T]`. - -Unbound static params will be inferred from expressions involving the `==` -operator and also when types dependent on them are being matched: - -.. code-block:: nim - type - MatrixReducer[M, N: static[int]; T] = concept x - x.reduce(SquareMatrix[N, T]) is array[M, int] - -The Nim compiler includes a simple linear equation solver, allowing it to -infer static params in some situations where integer arithmetic is involved. - -Just like in regular type classes, Nim discriminates between ``bind once`` -and ``bind many`` types when matching the concept. You can add the ``distinct`` -modifier to any of the otherwise inferable types to get a type that will be -matched without permanently inferring it. This may be useful when you need -to match several procs accepting the same wide class of types: - -.. code-block:: nim - type - Enumerable[T] = concept e - for v in e: - v is T - - type - MyConcept = concept o - # this could be inferred to a type such as Enumerable[int] - o.foo is distinct Enumerable - - # this could be inferred to a different type such as Enumerable[float] - o.bar is distinct Enumerable - - # it's also possible to give an alias name to a `bind many` type class - type Enum = distinct Enumerable - o.baz is Enum - -On the other hand, using ``bind once`` types allows you to test for equivalent -types used in multiple signatures, without actually requiring any concrete -types, thus allowing you to encode implementation-defined types: - -.. code-block:: nim - type - MyConcept = concept x - type T1 = auto - x.foo(T1) - x.bar(T1) # both procs must accept the same type - - type T2 = seq[SomeNumber] - x.alpha(T2) - x.omega(T2) # both procs must accept the same type - # and it must be a numeric sequence - -As seen in the previous examples, you can refer to generic concepts such as -`Enumerable[T]` just by their short name. Much like the regular generic types, -the concept will be automatically instantiated with the bind once auto type -in the place of each missing generic param. - -Please note that generic concepts such as `Enumerable[T]` can be matched -against concrete types such as `string`. Nim doesn't require the concept -type to have the same number of parameters as the type being matched. -If you wish to express a requirement towards the generic parameters of -the matched type, you can use a type mapping operator such as `genericHead` -or `stripGenericParams` within the body of the concept to obtain the -uninstantiated version of the type, which you can then try to instantiate -in any required way. For example, here is how one might define the classic -`Functor` concept from Haskell and then demonstrate that Nim's `Option[T]` -type is an instance of it: - -.. code-block:: nim - import future, typetraits - - type - Functor[A] = concept f - type MatchedGenericType = genericHead(f.type) - # `f` will be a value of a type such as `Option[T]` - # `MatchedGenericType` will become the `Option` type - - f.val is A - # The Functor should provide a way to obtain - # a value stored inside it - - type T = auto - map(f, A -> T) is MatchedGenericType[T] - # And it should provide a way to map one instance of - # the Functor to a instance of a different type, given - # a suitable `map` operation for the enclosed values - - import options - echo Option[int] is Functor # prints true - - -Concept derived values ----------------------- - -All top level constants or types appearing within the concept body are -accessible through the dot operator in procs where the concept was successfully -matched to a concrete type: - -.. code-block:: nim - type - DateTime = concept t1, t2, type T - const Min = T.MinDate - T.Now is T - - t1 < t2 is bool - - type TimeSpan = type(t1 - t2) - TimeSpan * int is TimeSpan - TimeSpan + TimeSpan is TimeSpan - - t1 + TimeSpan is T - - proc eventsJitter(events: Enumerable[DateTime]): float = - var - # this variable will have the inferred TimeSpan type for - # the concrete Date-like value the proc was called with: - averageInterval: DateTime.TimeSpan - - deviation: float - ... - - -Concept refinement ------------------- - -When the matched type within a concept is directly tested against a different -concept, we say that the outer concept is a refinement of the inner concept and -thus it is more-specific. When both concepts are matched in a call during -overload resolution, Nim will assign a higher precedence to the most specific -one. As an alternative way of defining concept refinements, you can use the -object inheritance syntax involving the ``of`` keyword: - -.. code-block:: nim - type - Graph = concept g, type G of EqualyComparable, Copyable - type - VertexType = G.VertexType - EdgeType = G.EdgeType - - VertexType is Copyable - EdgeType is Copyable - - var - v: VertexType - e: EdgeType - - IncidendeGraph = concept of Graph - # symbols such as variables and types from the refined - # concept are automatically in scope: - - g.source(e) is VertexType - g.target(e) is VertexType - - g.outgoingEdges(v) is Enumerable[EdgeType] - - BidirectionalGraph = concept g, type G - # The following will also turn the concept into a refinement when it - # comes to overload resolution, but it doesn't provide the convenient - # symbol inheritance - g is IncidendeGraph - - g.incomingEdges(G.VertexType) is Enumerable[G.EdgeType] - - proc f(g: IncidendeGraph) - proc f(g: BidirectionalGraph) # this one will be preferred if we pass a type - # matching the BidirectionalGraph concept - -.. - Converter type classes - ---------------------- - - Concepts can also be used to convert a whole range of types to a single type or - a small set of simpler types. This is achieved with a `return` statement within - the concept body: - - .. code-block:: nim - type - Stringable = concept x - $x is string - return $x - - StringRefValue[CharType] = object - base: ptr CharType - len: int - - StringRef = concept x - # the following would be an overloaded proc for cstring, string, seq and - # other user-defined types, returning either a StringRefValue[char] or - # StringRefValue[wchar] - return makeStringRefValue(x) - - # the varargs param will here be converted to an array of StringRefValues - # the proc will have only two instantiations for the two character types - proc log(format: static[string], varargs[StringRef]) - - # this proc will allow char and wchar values to be mixed in - # the same call at the cost of additional instantiations - # the varargs param will be converted to a tuple - proc log(format: static[string], varargs[distinct StringRef]) - - -.. - VTable types - ------------ - - Concepts allow Nim to define a great number of algorithms, using only - static polymorphism and without erasing any type information or sacrificing - any execution speed. But when polymorphic collections of objects are required, - the user must use one of the provided type erasure techniques - either common - base types or VTable types. - - VTable types are represented as "fat pointers" storing a reference to an - object together with a reference to a table of procs implementing a set of - required operations (the so called vtable). - - In contrast to other programming languages, the vtable in Nim is stored - externally to the object, allowing you to create multiple different vtable - views for the same object. Thus, the polymorphism in Nim is unbounded - - any type can implement an unlimited number of protocols or interfaces not - originally envisioned by the type's author. - - Any concept type can be turned into a VTable type by using the ``vtref`` - or the ``vtptr`` compiler magics. Under the hood, these magics generate - a converter type class, which converts the regular instances of the matching - types to the corresponding VTable type. - - .. code-block:: nim - type - IntEnumerable = vtref Enumerable[int] - - MyObject = object - enumerables: seq[IntEnumerable] - streams: seq[OutputStream.vtref] - - proc addEnumerable(o: var MyObject, e: IntEnumerable) = - o.enumerables.add e - - proc addStream(o: var MyObject, e: OutputStream.vtref) = - o.streams.add e - - The procs that will be included in the vtable are derived from the concept - body and include all proc calls for which all param types were specified as - concrete types. All such calls should include exactly one param of the type - matched against the concept (not necessarily in the first position), which - will be considered the value bound to the vtable. - - Overloads will be created for all captured procs, accepting the vtable type - in the position of the captured underlying object. - - Under these rules, it's possible to obtain a vtable type for a concept with - unbound type parameters or one instantiated with metatypes (type classes), - but it will include a smaller number of captured procs. A completely empty - vtable will be reported as an error. - - The ``vtref`` magic produces types which can be bound to ``ref`` types and - the ``vtptr`` magic produced types bound to ``ptr`` types. - - -Symbol lookup in generics -------------------------- - -Open and Closed symbols -~~~~~~~~~~~~~~~~~~~~~~~ - -The symbol binding rules in generics are slightly subtle: There are "open" and -"closed" symbols. A "closed" symbol cannot be re-bound in the instantiation -context, an "open" symbol can. Per default overloaded symbols are open -and every other symbol is closed. - -Open symbols are looked up in two different contexts: Both the context -at definition and the context at instantiation are considered: - -.. code-block:: nim - type - Index = distinct int - - proc `==` (a, b: Index): bool {.borrow.} - - var a = (0, 0.Index) - var b = (0, 0.Index) - - echo a == b # works! - -In the example the generic ``==`` for tuples (as defined in the system module) -uses the ``==`` operators of the tuple's components. However, the ``==`` for -the ``Index`` type is defined *after* the ``==`` for tuples; yet the example -compiles as the instantiation takes the currently defined symbols into account -too. - -Mixin statement ---------------- - -A symbol can be forced to be open by a `mixin`:idx: declaration: - -.. code-block:: nim - proc create*[T](): ref T = - # there is no overloaded 'init' here, so we need to state that it's an - # open symbol explicitly: - mixin init - new result - init result - - -Bind statement --------------- - -The ``bind`` statement is the counterpart to the ``mixin`` statement. It -can be used to explicitly declare identifiers that should be bound early (i.e. -the identifiers should be looked up in the scope of the template/generic -definition): - -.. code-block:: nim - # Module A - var - lastId = 0 - - template genId*: untyped = - bind lastId - inc(lastId) - lastId - -.. code-block:: nim - # Module B - import A - - echo genId() - -But a ``bind`` is rarely useful because symbol binding from the definition -scope is the default. - diff --git a/doc/manual/lexing.txt b/doc/manual/lexing.txt deleted file mode 100644 index 372de4d561..0000000000 --- a/doc/manual/lexing.txt +++ /dev/null @@ -1,420 +0,0 @@ -Lexical Analysis -================ - -Encoding --------- - -All Nim source files are in the UTF-8 encoding (or its ASCII subset).

If the next line only consists of a comment piece with -no other tokens between it and the preceding one, it does not start a new -comment: - - -.. code-block:: nim - i = 0 # This is a single comment over multiple lines. - # The scanner merges these two pieces. - # The comment continues here. - - -`Documentation comments`:idx: are comments that start with two ``##``. -Documentation comments are tokens; they are only allowed at certain places in -the input file as they belong to the syntax tree! - - -Multiline comments ------------------- - -Starting with version 0.13.0 of the language Nim supports multiline comments. -They look like: - -.. code-block:: nim - #[Comment here. - Multiple lines - are not a problem.]# - -Multiline comments support nesting: - -.. code-block:: nim - #[ #[ Multiline comment in already - commented out code. ]# - proc p[T](x: T) = discard - ]# - -Multiline documentation comments also exist and support nesting too: - -.. code-block:: nim - proc foo = - ##[Long documentation comment - here. - ]## - - -Identifiers & Keywords ----------------------- - -Identifiers in Nim can be any string of letters, digits -and underscores, beginning with a letter. Two immediate following -underscores ``__`` are not allowed:: - - letter ::= 'A'..'Z' | 'a'..'z' | '\x80'..'\xff' - digit ::= '0'..'9' - IDENTIFIER ::= letter ( ['_'] (letter | digit) )* - -Currently any Unicode character with an ordinal value > 127 (non ASCII) is -classified as a ``letter`` and may thus be part of an identifier but later -versions of the language may assign some Unicode characters to belong to the -operator characters instead. - -The following keywords are reserved and cannot be used as identifiers: - -.. code-block:: nim - :file: ../keywords.txt - -Some keywords are unused; they are reserved for future developments of the -language. - - -Identifier equality -------------------- - -Two identifiers are considered equal if the following algorithm returns true: - -.. code-block:: nim - proc sameIdentifier(a, b: string): bool = - a[0] == b[0] and - a.replace("_", "").toLowerAscii == b.replace("_", "").toLowerAscii - -That means only the first letters are compared in a case sensitive manner. Other -letters are compared case insensitively within the ASCII range and underscores are ignored. - -This rather unorthodox way to do identifier comparisons is called -`partial case insensitivity`:idx: and has some advantages over the conventional -case sensitivity: - -It allows programmers to mostly use their own preferred -spelling style, be it humpStyle or snake_style, and libraries written -by different programmers cannot use incompatible conventions. -A Nim-aware editor or IDE can show the identifiers as preferred. -Another advantage is that it frees the programmer from remembering -the exact spelling of an identifier. The exception with respect to the first -letter allows common code like ``var foo: Foo`` to be parsed unambiguously. - -Historically, Nim was a fully `style-insensitive`:idx: language. This meant that -it was not case-sensitive and underscores were ignored and there was no even a -distinction between ``foo`` and ``Foo``. - - -String literals ---------------- - -Terminal symbol in the grammar: ``STR_LIT``. - -String literals can be delimited by matching double quotes, and can -contain the following `escape sequences`:idx:\ : - -================== =================================================== - Escape sequence Meaning -================== =================================================== - ``\p`` platform specific newline: CRLF on Windows, - LF on Unix - ``\r``, ``\c`` `carriage return`:idx: - ``\n``, ``\l`` `line feed`:idx: (often called `newline`:idx:) - ``\f`` `form feed`:idx: - ``\t`` `tabulator`:idx: - ``\v`` `vertical tabulator`:idx: - ``\\`` `backslash`:idx: - ``\"`` `quotation mark`:idx: - ``\'`` `apostrophe`:idx: - ``\`` '0'..'9'+ `character with decimal value d`:idx:; - all decimal digits directly - following are used for the character - ``\a`` `alert`:idx: - ``\b`` `backspace`:idx: - ``\e`` `escape`:idx: `[ESC]`:idx: - ``\x`` HH `character with hex value HH`:idx:; - exactly two hex digits are allowed -================== =================================================== - - -Strings in Nim may contain any 8-bit value, even embedded zeros. However -some operations may interpret the first binary zero as a terminator. - - -Triple quoted string literals ------------------------------ - -Terminal symbol in the grammar: ``TRIPLESTR_LIT``. - -String literals can also be delimited by three double quotes -``"""`` ... ``"""``. -Literals in this form may run for several lines, may contain ``"`` and do not -interpret any escape sequences. -For convenience, when the opening ``"""`` is followed by a newline (there may -be whitespace between the opening ``"""`` and the newline), -the newline (and the preceding whitespace) is not included in the string. The -ending of the string literal is defined by the pattern ``"""[^"]``, so this: - -.. code-block:: nim - """"long string within quotes"""" - -Produces:: - - "long string within quotes" - - -Raw string literals -------------------- - -Terminal symbol in the grammar: ``RSTR_LIT``. - -There are also raw string literals that are preceded with the -letter ``r`` (or ``R``) and are delimited by matching double quotes (just -like ordinary string literals) and do not interpret the escape sequences. -This is especially convenient for regular expressions or Windows paths: - -.. code-block:: nim - - var f = openFile(r"C:\texts\text.txt") # a raw string, so ``\t`` is no tab - -To produce a single ``"`` within a raw string literal, it has to be doubled: - -.. code-block:: nim - - r"a""b" - -Produces:: - - a"b - -``r""""`` is not possible with this notation, because the three leading -quotes introduce a triple quoted string literal. ``r"""`` is the same -as ``"""`` since triple quoted string literals do not interpret escape -sequences either. - - -Generalized raw string literals -------------------------------- - -Terminal symbols in the grammar: ``GENERALIZED_STR_LIT``, -``GENERALIZED_TRIPLESTR_LIT``. - -The construct ``identifier"string literal"`` (without whitespace between the -identifier and the opening quotation mark) is a -generalized raw string literal. It is a shortcut for the construct -``identifier(r"string literal")``, so it denotes a procedure call with a -raw string literal as its only argument. Generalized raw string literals -are especially convenient for embedding mini languages directly into Nim -(for example regular expressions). - -The construct ``identifier"""string literal"""`` exists too. It is a shortcut -for ``identifier("""string literal""")``. - - -Character literals ------------------- - -Character literals are enclosed in single quotes ``''`` and can contain the -same escape sequences as strings - with one exception: the platform -dependent `newline`:idx: (``\p``) -is not allowed as it may be wider than one character (often it is the pair -CR/LF for example). Here are the valid `escape sequences`:idx: for character -literals: - -================== =================================================== - Escape sequence Meaning -================== =================================================== - ``\r``, ``\c`` `carriage return`:idx: - ``\n``, ``\l`` `line feed`:idx: - ``\f`` `form feed`:idx: - ``\t`` `tabulator`:idx: - ``\v`` `vertical tabulator`:idx: - ``\\`` `backslash`:idx: - ``\"`` `quotation mark`:idx: - ``\'`` `apostrophe`:idx: - ``\`` '0'..'9'+ `character with decimal value d`:idx:; - all decimal digits directly - following are used for the character - ``\a`` `alert`:idx: - ``\b`` `backspace`:idx: - ``\e`` `escape`:idx: `[ESC]`:idx: - ``\x`` HH `character with hex value HH`:idx:; - exactly two hex digits are allowed -================== =================================================== - -A character is not an Unicode character but a single byte. The reason for this -is efficiency: for the overwhelming majority of use-cases, the resulting -programs will still handle UTF-8 properly as UTF-8 was specially designed for -this. Another reason is that Nim can thus support ``array[char, int]`` or -``set[char]`` efficiently as many algorithms rely on this feature.

This is an **optimization** for the garbage -collector to not consider objects of this type as part of a cycle: - -.. code-block:: nim - type - Node = ref NodeObj - NodeObj {.acyclic, final.} = object - left, right: Node - data: string - -Or if we directly use a ref object: - -.. code-block:: nim - type - Node = ref object {.acyclic, final.} - left, right: Node - data: string - -In the example a tree structure is declared with the ``Node`` type. Note that -the type definition is recursive and the GC has to assume that objects of -this type may form a cyclic graph. The ``acyclic`` pragma passes the -information that this cannot happen to the GC. If the programmer uses the -``acyclic`` pragma for data types that are in reality cyclic, the GC may leak -memory, but nothing worse happens. - -**Future directions**: The ``acyclic`` pragma may become a property of a -``ref`` type: - -.. code-block:: nim - type - Node = acyclic ref NodeObj - NodeObj = object - left, right: Node - data: string - - -final pragma ------------- -The ``final`` pragma can be used for an object type to specify that it -cannot be inherited from. - - -shallow pragma --------------- -The ``shallow`` pragma affects the semantics of a type: The compiler is -allowed to make a shallow copy. This can cause serious semantic issues and -break memory safety! However, it can speed up assignments considerably, -because the semantics of Nim require deep copying of sequences and strings. -This can be expensive, especially if sequences are used to build a tree -structure: - -.. code-block:: nim - type - NodeKind = enum nkLeaf, nkInner - Node {.final, shallow.} = object - case kind: NodeKind - of nkLeaf: - strVal: string - of nkInner: - children: seq[Node] - - -pure pragma ------------ -An object type can be marked with the ``pure`` pragma so that its type -field which is used for runtime type identification is omitted. This used to be -necessary for binary compatibility with other compiled languages. - -An enum type can be marked as ``pure``. Then access of its fields always -requires full qualification. - - -asmNoStackFrame pragma ----------------------- -A proc can be marked with the ``asmNoStackFrame`` pragma to tell the compiler -it should not generate a stack frame for the proc. There are also no exit -statements like ``return result;`` generated and the generated C function is -declared as ``__declspec(naked)`` or ``__attribute__((naked))`` (depending on -the used C compiler). - -**Note**: This pragma should only be used by procs which consist solely of -assembler statements. - -error pragma ------------- -The ``error`` pragma is used to make the compiler output an error message -with the given content. Compilation does not necessarily abort after an error -though. - -The ``error`` pragma can also be used to -annotate a symbol (like an iterator or proc). The *usage* of the symbol then -triggers a compile-time error. This is especially useful to rule out that some -operation is valid due to overloading and type conversions: - -.. code-block:: nim - ## check that underlying int values are compared and not the pointers: - proc `==`(x, y: ptr int): bool {.error.} - - -fatal pragma ------------- -The ``fatal`` pragma is used to make the compiler output an error message -with the given content. In contrast to the ``error`` pragma, compilation -is guaranteed to be aborted by this pragma. Example: - -.. code-block:: nim - when not defined(objc): - {.fatal: "Compile this program with the objc command!".} - -warning pragma --------------- -The ``warning`` pragma is used to make the compiler output a warning message -with the given content. Compilation continues after the warning. - -hint pragma ------------ -The ``hint`` pragma is used to make the compiler output a hint message with -the given content. Compilation continues after the hint. - -line pragma ------------ -The ``line`` pragma can be used to affect line information of the annotated -statement as seen in stack backtraces: - -.. code-block:: nim - - template myassert*(cond: untyped, msg = "") = - if not cond: - # change run-time line information of the 'raise' statement: - {.line: InstantiationInfo().}: - raise newException(EAssertionFailed, msg) - -If the ``line`` pragma is used with a parameter, the parameter needs be a -``tuple[filename: string, line: int]``. If it is used without a parameter, -``system.InstantiationInfo()`` is used. - - -linearScanEnd pragma --------------------- -The ``linearScanEnd`` pragma can be used to tell the compiler how to -compile a Nim `case`:idx: statement. Syntactically it has to be used as a -statement: - -.. code-block:: nim - case myInt - of 0: - echo "most common case" - of 1: - {.linearScanEnd.} - echo "second most common case" - of 2: echo "unlikely: use branch table" - else: echo "unlikely too: use branch table for ", myInt - -In the example, the case branches ``0`` and ``1`` are much more common than -the other cases. Therefore the generated assembler code should test for these -values first, so that the CPU's branch predictor has a good chance to succeed -(avoiding an expensive CPU pipeline stall). The other cases might be put into a -jump table for O(1) overhead, but at the cost of a (very likely) pipeline -stall. - -The ``linearScanEnd`` pragma should be put into the last branch that should be -tested against via linear scanning. If put into the last branch of the -whole ``case`` statement, the whole ``case`` statement uses linear scanning. - - -computedGoto pragma -------------------- -The ``computedGoto`` pragma can be used to tell the compiler how to -compile a Nim `case`:idx: in a ``while true`` statement. -Syntactically it has to be used as a statement inside the loop: - -.. code-block:: nim - - type - MyEnum = enum - enumA, enumB, enumC, enumD, enumE - - proc vm() = - var instructions: array [0..100, MyEnum] - instructions[2] = enumC - instructions[3] = enumD - instructions[4] = enumA - instructions[5] = enumD - instructions[6] = enumC - instructions[7] = enumA - instructions[8] = enumB - - instructions[12] = enumE - var pc = 0 - while true: - {.computedGoto.} - let instr = instructions[pc] - case instr - of enumA: - echo "yeah A" - of enumC, enumD: - echo "yeah CD" - of enumB: - echo "yeah B" - of enumE: - break - inc(pc) - - vm() - -As the example shows ``computedGoto`` is mostly useful for interpreters. If -the underlying backend (C compiler) does not support the computed goto -extension the pragma is simply ignored. - - -unroll pragma -------------- -The ``unroll`` pragma can be used to tell the compiler that it should unroll -a `for`:idx: or `while`:idx: loop for runtime efficiency: - -.. code-block:: nim - proc searchChar(s: string, c: char): int = - for i in 0 .. s.high: - {.unroll: 4.} - if s[i] == c: return i - result = -1 - -In the above example, the search loop is unrolled by a factor 4. The unroll -factor can be left out too; the compiler then chooses an appropriate unroll -factor. - -**Note**: Currently the compiler recognizes but ignores this pragma. - - -immediate pragma ----------------- - -See `Typed vs untyped parameters`_. - - -compilation option pragmas --------------------------- -The listed pragmas here can be used to override the code generation options -for a proc/method/converter. - -The implementation currently provides the following possible options (various -others may be added later). - -=============== =============== ============================================ -pragma allowed values description -=============== =============== ============================================ -checks on|off Turns the code generation for all runtime - checks on or off. -boundChecks on|off Turns the code generation for array bound - checks on or off. -overflowChecks on|off Turns the code generation for over- or - underflow checks on or off. -nilChecks on|off Turns the code generation for nil pointer - checks on or off. -assertions on|off Turns the code generation for assertions - on or off. -warnings on|off Turns the warning messages of the compiler - on or off. -hints on|off Turns the hint messages of the compiler - on or off. -optimization none|speed|size Optimize the code for speed or size, or - disable optimization. -patterns on|off Turns the term rewriting templates/macros - on or off. -callconv cdecl|... Specifies the default calling convention for - all procedures (and procedure types) that - follow. -=============== =============== ============================================ - -Example: - -.. code-block:: nim - {.checks: off, optimization: speed.} - # compile without runtime checks and optimize for speed - - -push and pop pragmas --------------------- -The `push/pop`:idx: pragmas are very similar to the option directive, -but are used to override the settings temporarily. Example: - -.. code-block:: nim - {.push checks: off.} - # compile this section without runtime checks as it is - # speed critical - # ... some code ... - {.pop.} # restore old settings - - -register pragma ---------------- -The ``register`` pragma is for variables only. It declares the variable as -``register``, giving the compiler a hint that the variable should be placed -in a hardware register for faster access. C compilers usually ignore this -though and for good reasons: Often they do a better job without it anyway. - -In highly specific cases (a dispatch loop of a bytecode interpreter for -example) it may provide benefits, though. - - -global pragma -------------- -The ``global`` pragma can be applied to a variable within a proc to instruct -the compiler to store it in a global location and initialize it once at program -startup. - -.. code-block:: nim - proc isHexNumber(s: string): bool = - var pattern {.global.} = re"[0-9a-fA-F]+" - result = s.match(pattern) - -When used within a generic proc, a separate unique global variable will be -created for each instantiation of the proc. The order of initialization of -the created global variables within a module is not defined, but all of them -will be initialized after any top-level variables in their originating module -and before any variable in a module that imports it. - -deadCodeElim pragma -------------------- -The ``deadCodeElim`` pragma only applies to whole modules: It tells the -compiler to activate (or deactivate) dead code elimination for the module the -pragma appears in. - -The ``--deadCodeElim:on`` command line switch has the same effect as marking -every module with ``{.deadCodeElim:on}``. However, for some modules such as -the GTK wrapper it makes sense to *always* turn on dead code elimination - -no matter if it is globally active or not. - -Example: - -.. code-block:: nim - {.deadCodeElim: on.} - - -.. - NoForward pragma - ---------------- - The ``noforward`` pragma can be used to turn on and off a special compilation - mode that to large extent eliminates the need for forward declarations. In this - mode, the proc definitions may appear out of order and the compiler will postpone - their semantic analysis and compilation until it actually needs to generate code - using the definitions. In this regard, this mode is similar to the modus operandi - of dynamic scripting languages, where the function calls are not resolved until - the code is executed. Here is the detailed algorithm taken by the compiler: - - 1. When a callable symbol is first encountered, the compiler will only note the - symbol callable name and it will add it to the appropriate overload set in the - current scope. At this step, it won't try to resolve any of the type expressions - used in the signature of the symbol (so they can refer to other not yet defined - symbols). - - 2. When a top level call is encountered (usually at the very end of the module), - the compiler will try to determine the actual types of all of the symbols in the - matching overload set. This is a potentially recursive process as the signatures - of the symbols may include other call expressions, whose types will be resolved - at this point too. - - 3. Finally, after the best overload is picked, the compiler will start - compiling the body of the respective symbol. This in turn will lead the - compiler to discover more call expressions that need to be resolved and steps - 2 and 3 will be repeated as necessary. - - Please note that if a callable symbol is never used in this scenario, its body - will never be compiled. This is the default behavior leading to best compilation - times, but if exhaustive compilation of all definitions is required, using - ``nim check`` provides this option as well. - - Example: - - .. code-block:: nim - - {.noforward: on.} - - proc foo(x: int) = - bar x - - proc bar(x: int) = - echo x - - foo(10) - - -pragma pragma -------------- - -The ``pragma`` pragma can be used to declare user defined pragmas. This is -useful because Nim's templates and macros do not affect pragmas. User -defined pragmas are in a different module-wide scope than all other symbols. -They cannot be imported from a module. - -Example: - -.. code-block:: nim - when appType == "lib": - {.pragma: rtl, exportc, dynlib, cdecl.} - else: - {.pragma: rtl, importc, dynlib: "client.dll", cdecl.} - - proc p*(a, b: int): int {.rtl.} = - result = a+b - -In the example a new pragma named ``rtl`` is introduced that either imports -a symbol from a dynamic library or exports the symbol for dynamic library -generation. - - -Disabling certain messages --------------------------- -Nim generates some warnings and hints ("line too long") that may annoy the -user. A mechanism for disabling certain messages is provided: Each hint -and warning message contains a symbol in brackets. This is the message's -identifier that can be used to enable or disable it: - -.. code-block:: Nim - {.hint[LineTooLong]: off.} # turn off the hint about too long lines - -This is often better than disabling all warnings at once. - - -used pragma ------------ - -Nim produces a warning for symbols that are not exported and not used either. -The ``used`` pragma can be attached to a symbol to suppress this warning. This -is particularly useful when the symbol was generated by a macro: - -.. code-block:: nim - template implementArithOps(T) = - proc echoAdd(a, b: T) {.used.} = - echo a + b - proc echoSub(a, b: T) {.used.} = - echo a - b - - # no warning produced for the unused 'echoSub' - implementArithOps(int) - echoAdd 3, 5 - - - -experimental pragma -------------------- - -The ``experimental`` pragma enables experimental language features. Depending -on the concrete feature this means that the feature is either considered -too unstable for an otherwise stable release or that the future of the feature -is uncertain (it may be removed any time). - -Example: - -.. code-block:: nim - {.experimental.} - type - FooId = distinct int - BarId = distinct int - using - foo: FooId - bar: BarId - - proc useUsing(bar, foo) = - echo "bar is of type BarId" - echo "foo is of type FooId" - - -Implementation Specific Pragmas -=============================== - -This section describes additional pragmas that the current Nim implementation -supports but which should not be seen as part of the language specification. - -Bitsize pragma --------------- - -The ``bitsize`` pragma is for object field members. It declares the field as -a bitfield in C/C++. - -.. code-block:: Nim - type - mybitfield = object - flag {.bitsize:1.}: cuint - -generates: - -.. code-block:: C - struct mybitfield { - unsigned int flag:1; - }; - - -Volatile pragma ---------------- -The ``volatile`` pragma is for variables only. It declares the variable as -``volatile``, whatever that means in C/C++ (its semantics are not well defined -in C/C++). - -**Note**: This pragma will not exist for the LLVM backend. - - -NoDecl pragma -------------- -The ``noDecl`` pragma can be applied to almost any symbol (variable, proc, -type, etc.) and is sometimes useful for interoperability with C: -It tells Nim that it should not generate a declaration for the symbol in -the C code. For example: - -.. code-block:: Nim - var - EACCES {.importc, noDecl.}: cint # pretend EACCES was a variable, as - # Nim does not know its value - -However, the ``header`` pragma is often the better alternative. - -**Note**: This will not work for the LLVM backend. - - -Header pragma -------------- -The ``header`` pragma is very similar to the ``noDecl`` pragma: It can be -applied to almost any symbol and specifies that it should not be declared -and instead the generated code should contain an ``#include``: - -.. code-block:: Nim - type - PFile {.importc: "FILE*", header: "".} = distinct pointer - # import C's FILE* type; Nim will treat it as a new pointer type - -The ``header`` pragma always expects a string constant. The string contant -contains the header file: As usual for C, a system header file is enclosed -in angle brackets: ``<>``. If no angle brackets are given, Nim -encloses the header file in ``""`` in the generated C code. - -**Note**: This will not work for the LLVM backend. - - -IncompleteStruct pragma ------------------------ -The ``incompleteStruct`` pragma tells the compiler to not use the -underlying C ``struct`` in a ``sizeof`` expression: - -.. code-block:: Nim - type - DIR* {.importc: "DIR", header: "", - final, pure, incompleteStruct.} = object - - -Compile pragma --------------- -The ``compile`` pragma can be used to compile and link a C/C++ source file -with the project: - -.. code-block:: Nim - {.compile: "myfile.cpp".} - -**Note**: Nim computes a SHA1 checksum and only recompiles the file if it -has changed. You can use the ``-f`` command line option to force recompilation -of the file. - - -Link pragma ------------ -The ``link`` pragma can be used to link an additional file with the project: - -.. code-block:: Nim - {.link: "myfile.o".} - - -PassC pragma ------------- -The ``passC`` pragma can be used to pass additional parameters to the C -compiler like you would using the commandline switch ``--passC``: - -.. code-block:: Nim - {.passC: "-Wall -Werror".} - -Note that you can use ``gorge`` from the `system module `_ to -embed parameters from an external command at compile time: - -.. code-block:: Nim - {.passC: gorge("pkg-config --cflags sdl").} - -PassL pragma ------------- -The ``passL`` pragma can be used to pass additional parameters to the linker -like you would using the commandline switch ``--passL``: - -.. code-block:: Nim - {.passL: "-lSDLmain -lSDL".} - -Note that you can use ``gorge`` from the `system module `_ to -embed parameters from an external command at compile time: - -.. code-block:: Nim - {.passL: gorge("pkg-config --libs sdl").} - - -Emit pragma ------------ -The ``emit`` pragma can be used to directly affect the output of the -compiler's code generator. So it makes your code unportable to other code -generators/backends. Its usage is highly discouraged! However, it can be -extremely useful for interfacing with `C++`:idx: or `Objective C`:idx: code. - -Example: - -.. code-block:: Nim - {.emit: """ - static int cvariable = 420; - """.} - - {.push stackTrace:off.} - proc embedsC() = - var nimVar = 89 - # access Nim symbols within an emit section outside of string literals: - {.emit: ["""fprintf(stdout, "%d\n", cvariable + (int)""", nimVar, ");"].} - {.pop.} - - embedsC() - -For backwards compatibility, if the argument to the ``emit`` statement -is a single string literal, Nim symbols can be referred to via backticks. -This usage is however deprecated. - -For a toplevel emit statement the section where in the generated C/C++ file -the code should be emitted can be influenced via the -prefixes ``/*TYPESECTION*/`` or ``/*VARSECTION*/`` or ``/*INCLUDESECTION*/``: - -.. code-block:: Nim - {.emit: """/*TYPESECTION*/ - struct Vector3 { - public: - Vector3(): x(5) {} - Vector3(float x_): x(x_) {} - float x; - }; - """.} - - type Vector3 {.importcpp: "Vector3", nodecl} = object - x: cfloat - - proc constructVector3(a: cfloat): Vector3 {.importcpp: "Vector3(@)", nodecl} - - -ImportCpp pragma ----------------- - -**Note**: `c2nim `_ can parse a large subset of C++ and knows -about the ``importcpp`` pragma pattern language. It is not necessary -to know all the details described here. - - -Similar to the `importc pragma for C -<#foreign-function-interface-importc-pragma>`_, the -``importcpp`` pragma can be used to import `C++`:idx: methods or C++ symbols -in general. The generated code then uses the C++ method calling -syntax: ``obj->method(arg)``. In combination with the ``header`` and ``emit`` -pragmas this allows *sloppy* interfacing with libraries written in C++: - -.. code-block:: Nim - # Horrible example of how to interface with a C++ engine ... ;-) - - {.link: "/usr/lib/libIrrlicht.so".} - - {.emit: """ - using namespace irr; - using namespace core; - using namespace scene; - using namespace video; - using namespace io; - using namespace gui; - """.} - - const - irr = "" - - type - IrrlichtDeviceObj {.final, header: irr, - importcpp: "IrrlichtDevice".} = object - IrrlichtDevice = ptr IrrlichtDeviceObj - - proc createDevice(): IrrlichtDevice {. - header: irr, importcpp: "createDevice(@)".} - proc run(device: IrrlichtDevice): bool {. - header: irr, importcpp: "#.run(@)".} - -The compiler needs to be told to generate C++ (command ``cpp``) for -this to work. The conditional symbol ``cpp`` is defined when the compiler -emits C++ code. - - -Namespaces -~~~~~~~~~~ - -The *sloppy interfacing* example uses ``.emit`` to produce ``using namespace`` -declarations. It is usually much better to instead refer to the imported name -via the ``namespace::identifier`` notation: - -.. code-block:: nim - type - IrrlichtDeviceObj {.final, header: irr, - importcpp: "irr::IrrlichtDevice".} = object - - -Importcpp for enums -~~~~~~~~~~~~~~~~~~~ - -When ``importcpp`` is applied to an enum type the numerical enum values are -annotated with the C++ enum type, like in this example: ``((TheCppEnum)(3))``. -(This turned out to be the simplest way to implement it.) - - -Importcpp for procs -~~~~~~~~~~~~~~~~~~~ - -Note that the ``importcpp`` variant for procs uses a somewhat cryptic pattern -language for maximum flexibility: - -- A hash ``#`` symbol is replaced by the first or next argument. -- A dot following the hash ``#.`` indicates that the call should use C++'s dot - or arrow notation. -- An at symbol ``@`` is replaced by the remaining arguments, separated by - commas. - -For example: - -.. code-block:: nim - proc cppMethod(this: CppObj, a, b, c: cint) {.importcpp: "#.CppMethod(@)".} - var x: ptr CppObj - cppMethod(x[], 1, 2, 3) - -Produces: - -.. code-block:: C - x->CppMethod(1, 2, 3) - -As a special rule to keep backwards compatibility with older versions of the -``importcpp`` pragma, if there is no special pattern -character (any of ``# ' @``) at all, C++'s -dot or arrow notation is assumed, so the above example can also be written as: - -.. code-block:: nim - proc cppMethod(this: CppObj, a, b, c: cint) {.importcpp: "CppMethod".} - -Note that the pattern language naturally also covers C++'s operator overloading -capabilities: - -.. code-block:: nim - proc vectorAddition(a, b: Vec3): Vec3 {.importcpp: "# + #".} - proc dictLookup(a: Dict, k: Key): Value {.importcpp: "#[#]".} - - -- An apostrophe ``'`` followed by an integer ``i`` in the range 0..9 - is replaced by the i'th parameter *type*. The 0th position is the result - type. This can be used to pass types to C++ function templates. Between - the ``'`` and the digit an asterisk can be used to get to the base type - of the type. (So it "takes away a star" from the type; ``T*`` becomes ``T``.) - Two stars can be used to get to the element type of the element type etc. - -For example: - -.. code-block:: nim - - type Input {.importcpp: "System::Input".} = object - proc getSubsystem*[T](): ptr T {.importcpp: "SystemManager::getSubsystem<'*0>()", nodecl.} - - let x: ptr Input = getSubsystem[Input]() - -Produces: - -.. code-block:: C - x = SystemManager::getSubsystem() - - -- ``#@`` is a special case to support a ``cnew`` operation. It is required so - that the call expression is inlined directly, without going through a - temporary location. This is only required to circumvent a limitation of the - current code generator. - -For example C++'s ``new`` operator can be "imported" like this: - -.. code-block:: nim - proc cnew*[T](x: T): ptr T {.importcpp: "(new '*0#@)", nodecl.} - - # constructor of 'Foo': - proc constructFoo(a, b: cint): Foo {.importcpp: "Foo(@)".} - - let x = cnew constructFoo(3, 4) - -Produces: - -.. code-block:: C - x = new Foo(3, 4) - -However, depending on the use case ``new Foo`` can also be wrapped like this -instead: - -.. code-block:: nim - proc newFoo(a, b: cint): ptr Foo {.importcpp: "new Foo(@)".} - - let x = newFoo(3, 4) - - -Wrapping constructors -~~~~~~~~~~~~~~~~~~~~~ - -Sometimes a C++ class has a private copy constructor and so code like -``Class c = Class(1,2);`` must not be generated but instead ``Class c(1,2);``. -For this purpose the Nim proc that wraps a C++ constructor needs to be -annotated with the `constructor`:idx: pragma. This pragma also helps to generate -faster C++ code since construction then doesn't invoke the copy constructor: - -.. code-block:: nim - # a better constructor of 'Foo': - proc constructFoo(a, b: cint): Foo {.importcpp: "Foo(@)", constructor.} - - -Wrapping destructors -~~~~~~~~~~~~~~~~~~~~ - -Since Nim generates C++ directly, any destructor is called implicitly by the -C++ compiler at the scope exits. This means that often one can get away with -not wrapping the destructor at all! However when it needs to be invoked -explicitly, it needs to be wrapped. But the pattern language already provides -everything that is required for that: - -.. code-block:: nim - proc destroyFoo(this: var Foo) {.importcpp: "#.~Foo()".} - - -Importcpp for objects -~~~~~~~~~~~~~~~~~~~~~ - -Generic ``importcpp``'ed objects are mapped to C++ templates. This means that -you can import C++'s templates rather easily without the need for a pattern -language for object types: - -.. code-block:: nim - type - StdMap {.importcpp: "std::map", header: "".} [K, V] = object - proc `[]=`[K, V](this: var StdMap[K, V]; key: K; val: V) {. - importcpp: "#[#] = #", header: "".} - - var x: StdMap[cint, cdouble] - x[6] = 91.4 - - -Produces: - -.. code-block:: C - std::map x; - x[6] = 91.4; - - -- If more precise control is needed, the apostrophe ``'`` can be used in the - supplied pattern to denote the concrete type parameters of the generic type. - See the usage of the apostrophe operator in proc patterns for more details. - -.. code-block:: nim - - type - VectorIterator {.importcpp: "std::vector<'0>::iterator".} [T] = object - - var x: VectorIterator[cint] - - -Produces: - -.. code-block:: C - - std::vector::iterator x; - - -ImportObjC pragma ------------------ -Similar to the `importc pragma for C -<#foreign-function-interface-importc-pragma>`_, the ``importobjc`` pragma can -be used to import `Objective C`:idx: methods. The generated code then uses the -Objective C method calling syntax: ``[obj method param1: arg]``. -In addition with the ``header`` and ``emit`` pragmas this -allows *sloppy* interfacing with libraries written in Objective C: - -.. code-block:: Nim - # horrible example of how to interface with GNUStep ... - - {.passL: "-lobjc".} - {.emit: """ - #include - @interface Greeter:Object - { - } - - - (void)greet:(long)x y:(long)dummy; - @end - - #include - @implementation Greeter - - - (void)greet:(long)x y:(long)dummy - { - printf("Hello, World!\n"); - } - @end - - #include - """.} - - type - Id {.importc: "id", header: "", final.} = distinct int - - proc newGreeter: Id {.importobjc: "Greeter new", nodecl.} - proc greet(self: Id, x, y: int) {.importobjc: "greet", nodecl.} - proc free(self: Id) {.importobjc: "free", nodecl.} - - var g = newGreeter() - g.greet(12, 34) - g.free() - -The compiler needs to be told to generate Objective C (command ``objc``) for -this to work. The conditional symbol ``objc`` is defined when the compiler -emits Objective C code. - - -CodegenDecl pragma ------------------- - -The ``codegenDecl`` pragma can be used to directly influence Nim's code -generator. It receives a format string that determines how the variable -or proc is declared in the generated code. - -For variables $1 in the format string represents the type of the variable -and $2 is the name of the variable. - -The following Nim code: - -.. code-block:: nim - var - a {.codegenDecl: "$# progmem $#".}: int - -will generate this C code: - -.. code-block:: c - int progmem a - -For procedures $1 is the return type of the procedure, $2 is the name of -the procedure and $3 is the parameter list. - -The following nim code: - -.. code-block:: nim - proc myinterrupt() {.codegenDecl: "__interrupt $# $#$#".} = - echo "realistic interrupt handler" - -will generate this code: - -.. code-block:: c - __interrupt void myinterrupt() - - -InjectStmt pragma ------------------ - -The ``injectStmt`` pragma can be used to inject a statement before every -other statement in the current module.

Example: - -.. code-block:: nim - - proc toLower(c: char): char = # toLower for characters - if c in {'A'..'Z'}: - result = chr(ord(c) + (ord('a') - ord('A'))) - else: - result = c - - proc toLower(s: string): string = # toLower for strings - result = newString(len(s)) - for i in 0..len(s) - 1: - result[i] = toLower(s[i]) # calls toLower for characters; no recursion! - -Calling a procedure can be done in many different ways: - -.. code-block:: nim - proc callme(x, y: int, s: string = "", c: char, b: bool = false) = ... - - # call with positional arguments # parameter bindings: - callme(0, 1, "abc", '\t', true) # (x=0, y=1, s="abc", c='\t', b=true) - # call with named and positional arguments: - callme(y=1, x=0, "abd", '\t') # (x=0, y=1, s="abd", c='\t', b=false) - # call with named arguments (order is not relevant): - callme(c='\t', y=1, x=0) # (x=0, y=1, s="", c='\t', b=false) - # call as a command statement: no () needed: - callme 0, 1, "abc", '\t' # (x=0, y=1, s="abc", c='\t', b=false) - -A procedure may call itself recursively. - - -`Operators`:idx: are procedures with a special operator symbol as identifier: - -.. code-block:: nim - proc `$` (x: int): string = - # converts an integer to a string; this is a prefix operator. - result = intToStr(x) - -Operators with one parameter are prefix operators, operators with two -parameters are infix operators.

This command invocation syntax also works for -expressions, but then only a single argument may follow. This restriction -means ``echo f 1, f 2`` is parsed as ``echo(f(1), f(2))`` and not as -``echo(f(1, f(2)))``. The method call syntax may be used to provide one -more argument in this case: - -.. code-block:: nim - proc optarg(x: int, y: int = 0): int = x + y - proc singlearg(x: int): int = 20*x - - echo optarg 1, " ", singlearg 2 # prints "1 40" - - let fail = optarg 1, optarg 8 # Wrong. Too many arguments for a command call - let x = optarg(1, optarg 8) # traditional procedure call with 2 arguments - let y = 1.optarg optarg 8 # same thing as above, w/o the parenthesis - assert x == y - -The command invocation syntax also can't have complex expressions as arguments. -For example: (`anonymous procs`_), ``if``, ``case`` or ``try``. The (`do -notation`_) is limited, but usable for a single proc (see the example in the -corresponding section). Function calls with no arguments still needs () to -distinguish between a call and the function itself as a first class value. - - -Closures --------- - -Procedures can appear at the top level in a module as well as inside other -scopes, in which case they are called nested procs. A nested proc can access -local variables from its enclosing scope and if it does so it becomes a -closure. Any captured variables are stored in a hidden additional argument -to the closure (its environment) and they are accessed by reference by both -the closure and its enclosing scope (i.e. any modifications made to them are -visible in both places). The closure environment may be allocated on the heap -or on the stack if the compiler determines that this would be safe. - -Creating closures in loops -~~~~~~~~~~~~~~~~ - -Since closures capture local variables by reference it is often not wanted -behavior inside loop bodies. See `closureScope `_ -for details on how to change this behavior. - -Anonymous Procs ---------------- - -Procs can also be treated as expressions, in which case it's allowed to omit -the proc's name. - -.. code-block:: nim - var cities = @["Frankfurt", "Tokyo", "New York", "Kyiv"] - - cities.sort(proc (x,y: string): int = - cmp(x.len, y.len)) - - -Procs as expressions can appear both as nested procs and inside top level -executable code. - - -Do notation ------------ - -As a special more convenient notation, proc expressions involved in procedure -calls can use the ``do`` keyword: - -.. code-block:: nim - sort(cities) do (x,y: string) -> int: - cmp(x.len, y.len) - - # Less parenthesis using the method plus command syntax: - cities = cities.map do (x:string) -> string: - "City of " & x - - # In macros, the do notation is often used for quasi-quoting - macroResults.add quote do: - if not `ex`: - echo `info`, ": Check failed: ", `expString` - -``do`` is written after the parentheses enclosing the regular proc params. -The proc expression represented by the do block is appended to them. -In calls using the command syntax, the do block will bind to the immediately -preceeding expression, transforming it in a call. - -``do`` with parentheses is an anonymous ``proc``; however a ``do`` without -parentheses is just a block of code. The ``do`` notation can be used to -pass multiple blocks to a macro: - -.. code-block:: nim - macro performWithUndo(task, undo: untyped) = ... - - performWithUndo do: - # multiple-line block of code - # to perform the task - do: - # code to undo it - - -Nonoverloadable builtins ------------------------- - -The following builtin procs cannot be overloaded for reasons of implementation -simplicity (they require specialized semantic checking):: - - declared, defined, definedInScope, compiles, sizeOf, - is, shallowCopy, getAst, astToStr, spawn, procCall - -Thus they act more like keywords than like ordinary identifiers; unlike a -keyword however, a redefinition may `shadow`:idx: the definition in -the ``system`` module.

The argument passed to a var parameter has to be -an l-value. Var parameters are implemented as hidden pointers. The -above example is equivalent to: - -.. code-block:: nim - proc divmod(a, b: int; res, remainder: ptr int) = - res[] = a div b - remainder[] = a mod b - - var - x, y: int - divmod(8, 5, addr(x), addr(y)) - assert x == 1 - assert y == 3 - -In the examples, var parameters or pointers are used to provide two -return values. This can be done in a cleaner way by returning a tuple: - -.. code-block:: nim - proc divmod(a, b: int): tuple[res, remainder: int] = - (a div b, a mod b) - - var t = divmod(8, 5) - - assert t.res == 1 - assert t.remainder == 3 - -One can use `tuple unpacking`:idx: to access the tuple's fields: - -.. code-block:: nim - var (x, y) = divmod(8, 5) # tuple unpacking - assert x == 1 - assert y == 3 - - -**Note**: ``var`` parameters are never necessary for efficient parameter -passing. Since non-var parameters cannot be modified the compiler is always -free to pass arguments by reference if it considers it can speed up execution. - - -Var return type ---------------- - -A proc, converter or iterator may return a ``var`` type which means that the -returned value is an l-value and can be modified by the caller: - -.. code-block:: nim - var g = 0 - - proc WriteAccessToG(): var int = - result = g - - WriteAccessToG() = 6 - assert g == 6 - -It is a compile time error if the implicitly introduced pointer could be -used to access a location beyond its lifetime: - -.. code-block:: nim - proc WriteAccessToG(): var int = - var g = 0 - result = g # Error! - -For iterators, a component of a tuple return type can have a ``var`` type too: - -.. code-block:: nim - iterator mpairs(a: var seq[string]): tuple[key: int, val: var string] = - for i in 0..a.high: - yield (i, a[i]) - -In the standard library every name of a routine that returns a ``var`` type -starts with the prefix ``m`` per convention. - - -Overloading of the subscript operator -------------------------------------- - -The ``[]`` subscript operator for arrays/openarrays/sequences can be overloaded. - - -Multi-methods -============= - -Procedures always use static dispatch. Multi-methods use dynamic -dispatch. For dynamic dispatch to work on an object it should be a reference -type as well. - -.. code-block:: nim - type - Expression = ref object of RootObj ## abstract base class for an expression - Literal = ref object of Expression - x: int - PlusExpr = ref object of Expression - a, b: Expression - - method eval(e: Expression): int {.base.} = - # override this base method - quit "to override!" - - method eval(e: Literal): int = return e.x - - method eval(e: PlusExpr): int = - # watch out: relies on dynamic binding - result = eval(e.a) + eval(e.b) - - proc newLit(x: int): Literal = - new(result) - result.x = x - - proc newPlus(a, b: Expression): PlusExpr = - new(result) - result.a = a - result.b = b - - echo eval(newPlus(newPlus(newLit(1), newLit(2)), newLit(4))) - -In the example the constructors ``newLit`` and ``newPlus`` are procs -because they should use static binding, but ``eval`` is a method because it -requires dynamic binding. - -As can be seen in the example, base methods have to be annotated with -the `base`:idx: pragma. The ``base`` pragma also acts as a reminder for the -programmer that a base method ``m`` is used as the foundation to determine all -the effects that a call to ``m`` might cause. - -In a multi-method all parameters that have an object type are used for the -dispatching: - -.. code-block:: nim - type - Thing = ref object of RootObj - Unit = ref object of Thing - x: int - - method collide(a, b: Thing) {.base, inline.} = - quit "to override!" - - method collide(a: Thing, b: Unit) {.inline.} = - echo "1" - - method collide(a: Unit, b: Thing) {.inline.} = - echo "2" - - var a, b: Unit - new a - new b - collide(a, b) # output: 2 - - -Invocation of a multi-method cannot be ambiguous: collide 2 is preferred over -collide 1 because the resolution works from left to right. -In the example ``Unit, Thing`` is preferred over ``Thing, Unit``. - -**Performance note**: Nim does not produce a virtual method table, but -generates dispatch trees. This avoids the expensive indirect branch for method -calls and enables inlining. However, other optimizations like compile time -evaluation or dead code elimination do not work with methods. - - -Iterators and the for statement -=============================== - -The `for`:idx: statement is an abstract mechanism to iterate over the elements -of a container. It relies on an `iterator`:idx: to do so. Like ``while`` -statements, ``for`` statements open an `implicit block`:idx:, so that they -can be left with a ``break`` statement. - -The ``for`` loop declares iteration variables - their scope reaches until the -end of the loop body. The iteration variables' types are inferred by the -return type of the iterator. - -An iterator is similar to a procedure, except that it can be called in the -context of a ``for`` loop. Iterators provide a way to specify the iteration over -an abstract type. A key role in the execution of a ``for`` loop plays the -``yield`` statement in the called iterator. Whenever a ``yield`` statement is -reached the data is bound to the ``for`` loop variables and control continues -in the body of the ``for`` loop. The iterator's local variables and execution -state are automatically saved between calls. Example: - -.. code-block:: nim - # this definition exists in the system module - iterator items*(a: string): char {.inline.} = - var i = 0 - while i < len(a): - yield a[i] - inc(i) - - for ch in items("hello world"): # `ch` is an iteration variable - echo ch - -The compiler generates code as if the programmer would have written this: - -.. code-block:: nim - var i = 0 - while i < len(a): - var ch = a[i] - echo ch - inc(i) - -If the iterator yields a tuple, there can be as many iteration variables -as there are components in the tuple. The i'th iteration variable's type is -the type of the i'th component. In other words, implicit tuple unpacking in a -for loop context is supported. - -Implict items/pairs invocations -------------------------------- - -If the for loop expression ``e`` does not denote an iterator and the for loop -has exactly 1 variable, the for loop expression is rewritten to ``items(e)``; -ie. an ``items`` iterator is implicitly invoked: - -.. code-block:: nim - for x in [1,2,3]: echo x - -If the for loop has exactly 2 variables, a ``pairs`` iterator is implicitly -invoked. - -Symbol lookup of the identifiers ``items``/``pairs`` is performed after -the rewriting step, so that all overloads of ``items``/``pairs`` are taken -into account. - - -First class iterators ---------------------- - -There are 2 kinds of iterators in Nim: *inline* and *closure* iterators. -An `inline iterator`:idx: is an iterator that's always inlined by the compiler -leading to zero overhead for the abstraction, but may result in a heavy -increase in code size. Inline iterators are second class citizens; -They can be passed as parameters only to other inlining code facilities like -templates, macros and other inline iterators. - -In contrast to that, a `closure iterator`:idx: can be passed around more freely: - -.. code-block:: nim - iterator count0(): int {.closure.} = - yield 0 - - iterator count2(): int {.closure.} = - var x = 1 - yield x - inc x - yield x - - proc invoke(iter: iterator(): int {.closure.}) = - for x in iter(): echo x - - invoke(count0) - invoke(count2) - -Closure iterators have other restrictions than inline iterators: - -1. ``yield`` in a closure iterator can not occur in a ``try`` statement. -2. For now, a closure iterator cannot be evaluated at compile time. -3. ``return`` is allowed in a closure iterator (but rarely useful) and ends - iteration. -4. Neither inline nor closure iterators can be recursive. -5. Closure iterators are not supported by the js backend. - -Iterators that are neither marked ``{.closure.}`` nor ``{.inline.}`` explicitly -default to being inline, but this may change in future versions of the -implementation. - -The ``iterator`` type is always of the calling convention ``closure`` -implicitly; the following example shows how to use iterators to implement -a `collaborative tasking`:idx: system: - -.. code-block:: nim - # simple tasking: - type - Task = iterator (ticker: int) - - iterator a1(ticker: int) {.closure.} = - echo "a1: A" - yield - echo "a1: B" - yield - echo "a1: C" - yield - echo "a1: D" - - iterator a2(ticker: int) {.closure.} = - echo "a2: A" - yield - echo "a2: B" - yield - echo "a2: C" - - proc runTasks(t: varargs[Task]) = - var ticker = 0 - while true: - let x = t[ticker mod t.len] - if finished(x): break - x(ticker) - inc ticker - - runTasks(a1, a2) - -The builtin ``system.finished`` can be used to determine if an iterator has -finished its operation; no exception is raised on an attempt to invoke an -iterator that has already finished its work. - -Note that ``system.finished`` is error prone to use because it only returns -``true`` one iteration after the iterator has finished: - -.. code-block:: nim - iterator mycount(a, b: int): int {.closure.} = - var x = a - while x <= b: - yield x - inc x - - var c = mycount # instantiate the iterator - while not finished(c): - echo c(1, 3) - - # Produces - 1 - 2 - 3 - 0 - -Instead this code has to be used: - -.. code-block:: nim - var c = mycount # instantiate the iterator - while true: - let value = c(1, 3) - if finished(c): break # and discard 'value'! - echo value - -It helps to think that the iterator actually returns a -pair ``(value, done)`` and ``finished`` is used to access the hidden ``done`` -field. - - -Closure iterators are *resumable functions* and so one has to provide the -arguments to every call. To get around this limitation one can capture -parameters of an outer factory proc: - -.. code-block:: nim - proc mycount(a, b: int): iterator (): int = - result = iterator (): int = - var x = a - while x <= b: - yield x - inc x - - let foo = mycount(1, 4) - - for f in foo(): - echo f - -.. - Implicit return type - -------------------- - - Since inline iterators must always produce values that will be consumed in - a for loop, the compiler will implicitly use the ``auto`` return type if no - type is given by the user. In contrast, since closure iterators can be used - as a collaborative tasking system, ``void`` is a valid return type for them. - - -Converters -========== - -A converter is like an ordinary proc except that it enhances -the "implicitly convertible" type relation (see `Convertible relation`_): - -.. code-block:: nim - # bad style ahead: Nim is not C. - converter toBool(x: int): bool = x != 0 - - if 4: - echo "compiles" - - -A converter can also be explicitly invoked for improved readability.

In addition to this rule an assignment to the builtin ``result`` -symbol also triggers a mandatory ``void`` context for the subsequent expressions: - -.. code-block:: nim - proc invalid*(): string = - result = "foo" - "invalid" # Error: value of type 'string' has to be discarded - -.. code-block:: nim - proc valid*(): string = - let x = 317 - "valid" - - -Var statement -------------- - -Var statements declare new local and global variables and -initialize them. A comma separated list of variables can be used to specify -variables of the same type: - -.. code-block:: nim - - var - a: int = 0 - x, y, z: int - -If an initializer is given the type can be omitted: the variable is then of the -same type as the initializing expression. Variables are always initialized -with a default value if there is no initializing expression. The default -value depends on the type and is always a zero in binary. - -============================ ============================================== -Type default value -============================ ============================================== -any integer type 0 -any float 0.0 -char '\\0' -bool false -ref or pointer type nil -procedural type nil -sequence nil (*not* ``@[]``) -string nil (*not* "") -tuple[x: A, y: B, ...] (default(A), default(B), ...) - (analogous for objects) -array[0..., T] [default(T), ...] -range[T] default(T); this may be out of the valid range -T = enum cast[T](0); this may be an invalid value -============================ ============================================== - - -The implicit initialization can be avoided for optimization reasons with the -`noinit`:idx: pragma: - -.. code-block:: nim - var - a {.noInit.}: array [0..1023, char] - -If a proc is annotated with the ``noinit`` pragma this refers to its implicit -``result`` variable: - -.. code-block:: nim - proc returnUndefinedValue: int {.noinit.} = discard - - -The implicit initialization can be also prevented by the `requiresInit`:idx: -type pragma. The compiler requires an explicit initialization for the object -and all of its fields. However it does a `control flow analysis`:idx: to prove -the variable has been initialized and does not rely on syntactic properties: - -.. code-block:: nim - type - MyObject = object {.requiresInit.} - - proc p() = - # the following is valid: - var x: MyObject - if someCondition(): - x = a() - else: - x = a() - # use x - - -let statement -------------- - -A ``let`` statement declares new local and global `single assignment`:idx: -variables and binds a value to them. The syntax is the same as that of the ``var`` -statement, except that the keyword ``var`` is replaced by the keyword ``let``. -Let variables are not l-values and can thus not be passed to ``var`` parameters -nor can their address be taken. They cannot be assigned new values. - -For let variables the same pragmas are available as for ordinary variables. - - -Tuple unpacking ---------------- - -In a ``var`` or ``let`` statement tuple unpacking can be performed. The special -identifier ``_`` can be used to ignore some parts of the tuple: - -.. code-block:: nim - proc returnsTuple(): (int, int, int) = (4, 2, 3) - - let (x, _, z) = returnsTuple() - - - -Const section -------------- - -`Constants`:idx: are symbols which are bound to a value. The constant's value -cannot change. The compiler must be able to evaluate the expression in a -constant declaration at compile time. - -Nim contains a sophisticated compile-time evaluator, so procedures which -have no side-effect can be used in constant expressions too: - -.. code-block:: nim - import strutils - const - constEval = contains("abc", 'b') # computed at compile time! - - -The rules for compile-time computability are: - -1. Literals are compile-time computable. -2. Type conversions are compile-time computable. -3. Procedure calls of the form ``p(X)`` are compile-time computable if - ``p`` is a proc without side-effects (see the `noSideEffect pragma - <#pragmas-nosideeffect-pragma>`_ for details) and if ``X`` is a - (possibly empty) list of compile-time computable arguments. - - -Constants cannot be of type ``ptr``, ``ref`` or ``var``, nor can -they contain such a type. - - -Static statement/expression ---------------------------- - -A static statement/expression can be used to enforce compile -time evaluation explicitly. Enforced compile time evaluation can even evaluate -code that has side effects: - -.. code-block:: - - static: - echo "echo at compile time" - -It's a static error if the compiler cannot perform the evaluation at compile -time. - -The current implementation poses some restrictions for compile time -evaluation: Code which contains ``cast`` or makes use of the foreign function -interface cannot be evaluated at compile time. Later versions of Nim will -support the FFI at compile time. - - -If statement ------------- - -Example: - -.. code-block:: nim - - var name = readLine(stdin) - - if name == "Andreas": - echo "What a nice name!" - elif name == "": - echo "Don't you have a name?" - else: - echo "Boring name..." - -The ``if`` statement is a simple way to make a branch in the control flow: -The expression after the keyword ``if`` is evaluated, if it is true -the corresponding statements after the ``:`` are executed. Otherwise -the expression after the ``elif`` is evaluated (if there is an -``elif`` branch), if it is true the corresponding statements after -the ``:`` are executed. This goes on until the last ``elif``. If all -conditions fail, the ``else`` part is executed. If there is no ``else`` -part, execution continues with the next statement. - -In ``if`` statements new scopes begin immediately after the ``if``/``elif``/``else`` keywords and ends after the corresponding *then* block. -For visualization purposes the scopes have been enclosed in ``{| |}`` in the following example: - -.. code-block:: nim - if {| (let m = input =~ re"(\w+)=\w+"; m.isMatch): - echo "key ", m[0], " value ", m[1] |} - elif {| (let m = input =~ re""; m.isMatch): - echo "new m in this scope" |} - else: {| - echo "m not declared here" |} - -Case statement --------------- - -Example: - -.. code-block:: nim - - case readline(stdin) - of "delete-everything", "restart-computer": - echo "permission denied" - of "go-for-a-walk": echo "please yourself" - else: echo "unknown command" - - # indentation of the branches is also allowed; and so is an optional colon - # after the selecting expression: - case readline(stdin): - of "delete-everything", "restart-computer": - echo "permission denied" - of "go-for-a-walk": echo "please yourself" - else: echo "unknown command" - - -The ``case`` statement is similar to the if statement, but it represents -a multi-branch selection. The expression after the keyword ``case`` is -evaluated and if its value is in a *slicelist* the corresponding statements -(after the ``of`` keyword) are executed. If the value is not in any -given *slicelist* the ``else`` part is executed. If there is no ``else`` -part and not all possible values that ``expr`` can hold occur in a -``slicelist``, a static error occurs. This holds only for expressions of -ordinal types. "All possible values" of ``expr`` are determined by ``expr``'s -type. To suppress the static error an ``else`` part with an -empty ``discard`` statement should be used. - -For non ordinal types it is not possible to list every possible value and so -these always require an ``else`` part. - -As case statements perform compile-time exhaustiveness checks, the value in -every ``of`` branch must be known at compile time. This fact is also exploited -to generate more performant code. - -As a special semantic extension, an expression in an ``of`` branch of a case -statement may evaluate to a set or array constructor; the set or array is then -expanded into a list of its elements: - -.. code-block:: nim - const - SymChars: set[char] = {'a'..'z', 'A'..'Z', '\x80'..'\xFF'} - - proc classify(s: string) = - case s[0] - of SymChars, '_': echo "an identifier" - of '0'..'9': echo "a number" - else: echo "other" - - # is equivalent to: - proc classify(s: string) = - case s[0] - of 'a'..'z', 'A'..'Z', '\x80'..'\xFF', '_': echo "an identifier" - of '0'..'9': echo "a number" - else: echo "other" - - -When statement --------------- - -Example: - -.. code-block:: nim - - when sizeof(int) == 2: - echo "running on a 16 bit system!" - elif sizeof(int) == 4: - echo "running on a 32 bit system!" - elif sizeof(int) == 8: - echo "running on a 64 bit system!" - else: - echo "cannot happen!" - -The ``when`` statement is almost identical to the ``if`` statement with some -exceptions: - -* Each condition (``expr``) has to be a constant expression (of type ``bool``). -* The statements do not open a new scope. -* The statements that belong to the expression that evaluated to true are - translated by the compiler, the other statements are not checked for - semantics! However, each condition is checked for semantics. - -The ``when`` statement enables conditional compilation techniques. As -a special syntactic extension, the ``when`` construct is also available -within ``object`` definitions. - - -When nimvm statement --------------------- - -``nimvm`` is a special symbol, that may be used as expression of ``when nimvm`` -statement to differentiate execution path between runtime and compile time. - -Example: - -.. code-block:: nim - proc someProcThatMayRunInCompileTime(): bool = - when nimvm: - # This code runs in compile time - result = true - else: - # This code runs in runtime - result = false - const ctValue = someProcThatMayRunInCompileTime() - let rtValue = someProcThatMayRunInCompileTime() - assert(ctValue == true) - assert(rtValue == false) - -``when nimvm`` statement must meet the following requirements: - -* Its expression must always be ``nimvm``. More complex expressions are not - allowed. -* It must not contain ``elif`` branches. -* It must contain ``else`` branch. -* Code in branches must not affect semantics of the code that follows the - ``when nimvm`` statement. E.g. it must not define symbols that are used in - the following code. - -Return statement ----------------- - -Example: - -.. code-block:: nim - return 40+2 - -The ``return`` statement ends the execution of the current procedure. -It is only allowed in procedures. If there is an ``expr``, this is syntactic -sugar for: - -.. code-block:: nim - result = expr - return result - - -``return`` without an expression is a short notation for ``return result`` if -the proc has a return type. The `result`:idx: variable is always the return -value of the procedure. It is automatically declared by the compiler. As all -variables, ``result`` is initialized to (binary) zero: - -.. code-block:: nim - proc returnZero(): int = - # implicitly returns 0 - - -Yield statement ---------------- - -Example: - -.. code-block:: nim - yield (1, 2, 3) - -The ``yield`` statement is used instead of the ``return`` statement in -iterators. It is only valid in iterators. Execution is returned to the body -of the for loop that called the iterator. Yield does not end the iteration -process, but execution is passed back to the iterator if the next iteration -starts. See the section about iterators (`Iterators and the for statement`_) -for further information. - - -Block statement ---------------- - -Example: - -.. code-block:: nim - var found = false - block myblock: - for i in 0..3: - for j in 0..3: - if a[j][i] == 7: - found = true - break myblock # leave the block, in this case both for-loops - echo found - -The block statement is a means to group statements to a (named) ``block``. -Inside the block, the ``break`` statement is allowed to leave the block -immediately. A ``break`` statement can contain a name of a surrounding -block to specify which block is to leave. - - -Break statement ---------------- - -Example: - -.. code-block:: nim - break - -The ``break`` statement is used to leave a block immediately. If ``symbol`` -is given, it is the name of the enclosing block that is to leave. If it is -absent, the innermost block is left. - - -While statement ---------------- - -Example: - -.. code-block:: nim - echo "Please tell me your password:" - var pw = readLine(stdin) - while pw != "12345": - echo "Wrong password! Next try:" - pw = readLine(stdin) - - -The ``while`` statement is executed until the ``expr`` evaluates to false. -Endless loops are no error. ``while`` statements open an `implicit block`, -so that they can be left with a ``break`` statement. - - -Continue statement ------------------- - -A ``continue`` statement leads to the immediate next iteration of the -surrounding loop construct. It is only allowed within a loop. A continue -statement is syntactic sugar for a nested block: - -.. code-block:: nim - while expr1: - stmt1 - continue - stmt2 - -Is equivalent to: - -.. code-block:: nim - while expr1: - block myBlockName: - stmt1 - break myBlockName - stmt2 - - -Assembler statement -------------------- - -The direct embedding of assembler code into Nim code is supported -by the unsafe ``asm`` statement. Identifiers in the assembler code that refer to -Nim identifiers shall be enclosed in a special character which can be -specified in the statement's pragmas. The default special character is ``'`'``: - -.. code-block:: nim - {.push stackTrace:off.} - proc addInt(a, b: int): int = - # a in eax, and b in edx - asm """ - mov eax, `a` - add eax, `b` - jno theEnd - call `raiseOverflow` - theEnd: - """ - {.pop.} - -If the GNU assembler is used, quotes and newlines are inserted automatically: - -.. code-block:: nim - proc addInt(a, b: int): int = - asm """ - addl %%ecx, %%eax - jno 1 - call `raiseOverflow` - 1: - :"=a"(`result`) - :"a"(`a`), "c"(`b`) - """ - -Instead of: - -.. code-block:: nim - proc addInt(a, b: int): int = - asm """ - "addl %%ecx, %%eax\n" - "jno 1\n" - "call `raiseOverflow`\n" - "1: \n" - :"=a"(`result`) - :"a"(`a`), "c"(`b`) - """ - -Using statement ---------------- - -The using statement provides syntactic convenience in modules where -the same parameter names and types are used over and over. Instead of: - -.. code-block:: nim - proc foo(c: Context; n: Node) = ... - proc bar(c: Context; n: Node, counter: int) = ... - proc baz(c: Context; n: Node) = ... - -One can tell the compiler about the convention that a parameter of -name ``c`` should default to type ``Context``, ``n`` should default to -``Node`` etc.: - -.. code-block:: nim - using - c: Context - n: Node - counter: int - - proc foo(c, n) = ... - proc bar(c, n, counter) = ... - proc baz(c, n) = ... - - -The ``using`` section uses the same indentation based grouping syntax as -a ``var`` or ``let`` section. - -Note that ``using`` is not applied for ``template`` since untyped template -parameters default to the type ``system.untyped``. - - -If expression -------------- - -An `if expression` is almost like an if statement, but it is an expression. -Example: - -.. code-block:: nim - var y = if x > 8: 9 else: 10 - -An if expression always results in a value, so the ``else`` part is -required. ``Elif`` parts are also allowed. - -When expression ---------------- - -Just like an `if expression`, but corresponding to the when statement. - -Case expression ---------------- - -The `case expression` is again very similar to the case statement: - -.. code-block:: nim - var favoriteFood = case animal - of "dog": "bones" - of "cat": "mice" - elif animal.endsWith"whale": "plankton" - else: - echo "I'm not sure what to serve, but everybody loves ice cream" - "ice cream" - -As seen in the above example, the case expression can also introduce side -effects. When multiple statements are given for a branch, Nim will use -the last expression as the result value, much like in an `expr` template. - -Table constructor ------------------ - -A table constructor is syntactic sugar for an array constructor: - -.. code-block:: nim - {"key1": "value1", "key2", "key3": "value2"} - - # is the same as: - [("key1", "value1"), ("key2", "value2"), ("key3", "value2")] - - -The empty table can be written ``{:}`` (in contrast to the empty set -which is ``{}``) which is thus another way to write as the empty array -constructor ``[]``. This slightly unusual way of supporting tables -has lots of advantages: - -* The order of the (key,value)-pairs is preserved, thus it is easy to - support ordered dicts with for example ``{key: val}.newOrderedTable``. -* A table literal can be put into a ``const`` section and the compiler - can easily put it into the executable's data section just like it can - for arrays and the generated data section requires a minimal amount - of memory. -* Every table implementation is treated equal syntactically. -* Apart from the minimal syntactic sugar the language core does not need to - know about tables. - - -Type conversions ----------------- -Syntactically a `type conversion` is like a procedure call, but a -type name replaces the procedure name. A type conversion is always -safe in the sense that a failure to convert a type to another -results in an exception (if it cannot be determined statically). - -Ordinary procs are often preferred over type conversions in Nim: For instance, -``$`` is the ``toString`` operator by convention and ``toFloat`` and ``toInt`` -can be used to convert from floating point to integer or vice versa. - - -Type casts ----------- -Example: - -.. code-block:: nim - cast[int](x) - -Type casts are a crude mechanism to interpret the bit pattern of -an expression as if it would be of another type. Type casts are -only needed for low-level programming and are inherently unsafe. - - -The addr operator ------------------ -The ``addr`` operator returns the address of an l-value. If the type of the -location is ``T``, the `addr` operator result is of the type ``ptr T``. An -address is always an untraced reference. Taking the address of an object that -resides on the stack is **unsafe**, as the pointer may live longer than the -object on the stack and can thus reference a non-existing object. One can get -the address of variables, but one can't use it on variables declared through -``let`` statements: - -.. code-block:: nim - - let t1 = "Hello" - var - t2 = t1 - t3 : pointer = addr(t2) - echo repr(addr(t2)) - # --> ref 0x7fff6b71b670 --> 0x10bb81050"Hello" - echo cast[ptr string](t3)[] - # --> Hello - # The following line doesn't compile: - echo repr(addr(t1)) - # Error: expression has no address diff --git a/doc/manual/syntax.txt b/doc/manual/syntax.txt deleted file mode 100644 index f3ace9f563..0000000000 --- a/doc/manual/syntax.txt +++ /dev/null @@ -1,81 +0,0 @@ -Syntax -====== - -This section lists Nim's standard syntax.

Most symbols are -bound from the definition scope of the template: - -.. code-block:: nim - # Module A - var - lastId = 0 - - template genId*: untyped = - inc(lastId) - lastId - -.. code-block:: nim - # Module B - import A - - echo genId() # Works as 'lastId' has been bound in 'genId's defining scope - -As in generics symbol binding can be influenced via ``mixin`` or ``bind`` -statements. - - - -Identifier construction ------------------------ - -In templates identifiers can be constructed with the backticks notation: - -.. code-block:: nim - - template typedef(name: untyped, typ: typedesc) = - type - `T name`* {.inject.} = typ - `P name`* {.inject.} = ref `T name` - - typedef(myint, int) - var x: PMyInt - -In the example ``name`` is instantiated with ``myint``, so \`T name\` becomes -``Tmyint``. - - -Lookup rules for template parameters ------------------------------------- - -A parameter ``p`` in a template is even substituted in the expression ``x.p``. -Thus template arguments can be used as field names and a global symbol can be -shadowed by the same argument name even when fully qualified: - -.. code-block:: nim - # module 'm' - - type - Lev = enum - levA, levB - - var abclev = levB - - template tstLev(abclev: Lev) = - echo abclev, " ", m.abclev - - tstLev(levA) - # produces: 'levA levA' - -But the global symbol can properly be captured by a ``bind`` statement: - -.. code-block:: nim - # module 'm' - - type - Lev = enum - levA, levB - - var abclev = levB - - template tstLev(abclev: Lev) = - bind m.abclev - echo abclev, " ", m.abclev - - tstLev(levA) - # produces: 'levA levB' - - -Hygiene in templates --------------------- - -Per default templates are `hygienic`:idx:\: Local identifiers declared in a -template cannot be accessed in the instantiation context: - -.. code-block:: nim - - template newException*(exceptn: typedesc, message: string): untyped = - var - e: ref exceptn # e is implicitly gensym'ed here - new(e) - e.msg = message - e - - # so this works: - let e = "message" - raise newException(EIO, e) - - -Whether a symbol that is declared in a template is exposed to the instantiation -scope is controlled by the `inject`:idx: and `gensym`:idx: pragmas: gensym'ed -symbols are not exposed but inject'ed are. - -The default for symbols of entity ``type``, ``var``, ``let`` and ``const`` -is ``gensym`` and for ``proc``, ``iterator``, ``converter``, ``template``, -``macro`` is ``inject``.

Therefore the dot syntax has some limitations when it -is used to invoke templates/macros: - -.. code-block:: nim - template declareVar(name: untyped) = - const name {.inject.} = 45 - - # Doesn't compile: - unknownIdentifier.declareVar - - -Another common example is this: - -.. code-block:: nim - from sequtils import toSeq - - iterator something: string = - yield "Hello" - yield "World" - - var info = toSeq(something()) - -The problem here is that the compiler already decided that ``something()`` as -an iterator is not callable in this context before ``toSeq`` gets its -chance to convert it into a sequence. - - -Macros -====== - -A macro is a special kind of low level template. Macros can be used -to implement `domain specific languages`:idx:. - -While macros enable advanced compile-time code transformations, they -cannot change Nim's syntax.

This is why ``debug`` iterates over all of ``n``'s -children. - - -BindSym -------- - -The above ``debug`` macro relies on the fact that ``write``, ``writeLine`` and -``stdout`` are declared in the system module and thus visible in the -instantiating context. There is a way to use bound identifiers -(aka `symbols`:idx:) instead of using unbound identifiers. The ``bindSym`` -builtin can be used for that: - -.. code-block:: nim - import macros - - macro debug(n: varargs[typed]): untyped = - result = newNimNode(nnkStmtList, n) - for x in n: - # we can bind symbols in scope via 'bindSym': - add(result, newCall(bindSym"write", bindSym"stdout", toStrLit(x))) - add(result, newCall(bindSym"write", bindSym"stdout", newStrLitNode(": "))) - add(result, newCall(bindSym"writeLine", bindSym"stdout", x)) - - var - a: array [0..10, int] - x = "some string" - a[0] = 42 - a[1] = 45 - - debug(a[0], a[1], x) - -The macro call expands to: - -.. code-block:: nim - write(stdout, "a[0]") - write(stdout, ": ") - writeLine(stdout, a[0]) - - write(stdout, "a[1]") - write(stdout, ": ") - writeLine(stdout, a[1]) - - write(stdout, "x") - write(stdout, ": ") - writeLine(stdout, x) - -However, the symbols ``write``, ``writeLine`` and ``stdout`` are already bound -and are not looked up again. As the example shows, ``bindSym`` does work with -overloaded symbols implicitly. - - -Statement Macros ----------------- - -Statement macros are defined just as expression macros. However, they are -invoked by an expression following a colon. - -The following example outlines a macro that generates a lexical analyzer from -regular expressions: - -.. code-block:: nim - import macros - - macro case_token(n: untyped): untyped = - # creates a lexical analyzer from regular expressions - # ...

Let ``T`` be ``f``'s return type. If ``T`` is ``void`` -then ``spawn``'s return type is also ``void`` otherwise it is ``FlowVar[T]``. - -Within a ``parallel`` section sometimes the ``FlowVar[T]`` is eliminated -to ``T``.

This deep copy - is performed via ``system.deepCopy`` and so can be overridden. -* For *safe* data exchange between ``f`` and the caller a global ``TChannel`` - needs to be used.

These unsigned operations for signed integers use -the ``%`` suffix as convention: - - -====================== ====================================================== -operation meaning -====================== ====================================================== -``a +% b`` unsigned integer addition -``a -% b`` unsigned integer subtraction -``a *% b`` unsigned integer multiplication -``a /% b`` unsigned integer division -``a %% b`` unsigned integer modulo operation -``a <% b`` treat ``a`` and ``b`` as unsigned and compare -``a <=% b`` treat ``a`` and ``b`` as unsigned and compare -``ze(a)`` extends the bits of ``a`` with zeros until it has the - width of the ``int`` type -``toU8(a)`` treats ``a`` as unsigned and converts it to an - unsigned integer of 8 bits (but still the - ``int8`` type) -``toU16(a)`` treats ``a`` as unsigned and converts it to an - unsigned integer of 16 bits (but still the - ``int16`` type) -``toU32(a)`` treats ``a`` as unsigned and converts it to an - unsigned integer of 32 bits (but still the - ``int32`` type) -====================== ====================================================== - -`Automatic type conversion`:idx: is performed in expressions where different -kinds of integer types are used: the smaller type is converted to the larger. - -A `narrowing type conversion`:idx: converts a larger to a smaller type (for -example ``int32 -> int16``. A `widening type conversion`:idx: converts a -smaller type to a larger type (for example ``int16 -> int32``). In Nim only -widening type conversions are *implicit*: - -.. code-block:: nim - var myInt16 = 5i16 - var myInt: int - myInt16 + 34 # of type ``int16`` - myInt16 + myInt # of type ``int`` - myInt16 + 2i32 # of type ``int32`` - -However, ``int`` literals are implicitly convertible to a smaller integer type -if the literal's value fits this smaller type and such a conversion is less -expensive than other implicit conversions, so ``myInt16 + 34`` produces -an ``int16`` result. - -For further details, see `Convertible relation -<#type-relations-convertible-relation>`_. - - -Subrange types --------------- -A subrange type is a range of values from an ordinal type (the base -type). To define a subrange type, one must specify it's limiting values: the -lowest and highest value of the type: - -.. code-block:: nim - type - Subrange = range[0..5] - - -``Subrange`` is a subrange of an integer which can only hold the values 0 -to 5. Assigning any other value to a variable of type ``Subrange`` is a -checked runtime error (or static error if it can be statically -determined). Assignments from the base type to one of its subrange types -(and vice versa) are allowed. - -A subrange type has the same size as its base type (``int`` in the example). - - -Pre-defined floating point types --------------------------------- - -The following floating point types are pre-defined: - -``float`` - the generic floating point type; its size is platform dependent - (the compiler chooses the processor's fastest floating point type). - This type should be used in general. - -floatXX - an implementation may define additional floating point types of XX bits using - this naming scheme (example: float64 is a 64 bit wide float). The current - implementation supports ``float32`` and ``float64``. Literals of these types - have the suffix 'fXX. - - -Automatic type conversion in expressions with different kinds -of floating point types is performed: See `Convertible relation`_ for further -details. Arithmetic performed on floating point types follows the IEEE -standard. Integer types are not converted to floating point types automatically -and vice versa. - -The IEEE standard defines five types of floating-point exceptions: - -* Invalid: operations with mathematically invalid operands, - for example 0.0/0.0, sqrt(-1.0), and log(-37.8). -* Division by zero: divisor is zero and dividend is a finite nonzero number, - for example 1.0/0.0. -* Overflow: operation produces a result that exceeds the range of the exponent, - for example MAXDOUBLE+0.0000000000001e308. -* Underflow: operation produces a result that is too small to be represented - as a normal number, for example, MINDOUBLE * MINDOUBLE. -* Inexact: operation produces a result that cannot be represented with infinite - precision, for example, 2.0 / 3.0, log(1.1) and 0.1 in input. - -The IEEE exceptions are either ignored at runtime or mapped to the -Nim exceptions: `FloatInvalidOpError`:idx:, `FloatDivByZeroError`:idx:, -`FloatOverflowError`:idx:, `FloatUnderflowError`:idx:, -and `FloatInexactError`:idx:. -These exceptions inherit from the `FloatingPointError`:idx: base class. - -Nim provides the pragmas `nanChecks`:idx: and `infChecks`:idx: to control -whether the IEEE exceptions are ignored or trap a Nim exception: - -.. code-block:: nim - {.nanChecks: on, infChecks: on.} - var a = 1.0 - var b = 0.0 - echo b / b # raises FloatInvalidOpError - echo a / b # raises FloatOverflowError - -In the current implementation ``FloatDivByZeroError`` and ``FloatInexactError`` -are never raised. ``FloatOverflowError`` is raised instead of -``FloatDivByZeroError``. -There is also a `floatChecks`:idx: pragma that is a short-cut for the -combination of ``nanChecks`` and ``infChecks`` pragmas. ``floatChecks`` are -turned off as default. - -The only operations that are affected by the ``floatChecks`` pragma are -the ``+``, ``-``, ``*``, ``/`` operators for floating point types. - -An implementation should always use the maximum precision available to evaluate -floating pointer values at compile time; this means expressions like -``0.09'f32 + 0.01'f32 == 0.09'f64 + 0.01'f64`` are true. - - -Boolean type ------------- -The boolean type is named `bool`:idx: in Nim and can be one of the two -pre-defined values ``true`` and ``false``. Conditions in ``while``, -``if``, ``elif``, ``when``-statements need to be of type ``bool``. - -This condition holds:: - - ord(false) == 0 and ord(true) == 1 - -The operators ``not, and, or, xor, <, <=, >, >=, !=, ==`` are defined -for the bool type. The ``and`` and ``or`` operators perform short-cut -evaluation. Example: - -.. code-block:: nim - - while p != nil and p.name != "xyz": - # p.name is not evaluated if p == nil - p = p.next - - -The size of the bool type is one byte. - - -Character type --------------- -The character type is named ``char`` in Nim. Its size is one byte. -Thus it cannot represent an UTF-8 character, but a part of it. -The reason for this is efficiency: for the overwhelming majority of use-cases, -the resulting programs will still handle UTF-8 properly as UTF-8 was specially -designed for this. -Another reason is that Nim can support ``array[char, int]`` or -``set[char]`` efficiently as many algorithms rely on this feature. The -`Rune` type is used for Unicode characters, it can represent any Unicode -character. ``Rune`` is declared in the `unicode module `_. - - - - -Enumeration types ------------------ -Enumeration types define a new type whose values consist of the ones -specified. The values are ordered. Example: - -.. code-block:: nim - - type - Direction = enum - north, east, south, west - - -Now the following holds:: - - ord(north) == 0 - ord(east) == 1 - ord(south) == 2 - ord(west) == 3 - -Thus, north < east < south < west. The comparison operators can be used -with enumeration types. - -For better interfacing to other programming languages, the fields of enum -types can be assigned an explicit ordinal value. However, the ordinal values -have to be in ascending order. A field whose ordinal value is not -explicitly given is assigned the value of the previous field + 1. - -An explicit ordered enum can have *holes*: - -.. code-block:: nim - type - TokenType = enum - a = 2, b = 4, c = 89 # holes are valid - -However, it is then not an ordinal anymore, so it is not possible to use these -enums as an index type for arrays. The procedures ``inc``, ``dec``, ``succ`` -and ``pred`` are not available for them either. - - -The compiler supports the built-in stringify operator ``$`` for enumerations. -The stringify's result can be controlled by explicitly giving the string -values to use: - -.. code-block:: nim - - type - MyEnum = enum - valueA = (0, "my value A"), - valueB = "value B", - valueC = 2, - valueD = (3, "abc") - -As can be seen from the example, it is possible to both specify a field's -ordinal value and its string value by using a tuple. It is also -possible to only specify one of them. - -An enum can be marked with the ``pure`` pragma so that it's fields are not -added to the current scope, so they always need to be accessed -via ``MyEnum.value``: - -.. code-block:: nim - - type - MyEnum {.pure.} = enum - valueA, valueB, valueC, valueD - - echo valueA # error: Unknown identifier - echo MyEnum.valueA # works - - -String type ------------ -All string literals are of the type ``string``. A string in Nim is very -similar to a sequence of characters. However, strings in Nim are both -zero-terminated and have a length field. One can retrieve the length with the -builtin ``len`` procedure; the length never counts the terminating zero. -The assignment operator for strings always copies the string. -The ``&`` operator concatenates strings. - -Most native Nim types support conversion to strings with the special ``$`` proc. -When calling the ``echo`` proc, for example, the built-in stringify operation -for the parameter is called: - -.. code-block:: nim - - echo 3 # calls `$` for `int` - -Whenever a user creates a specialized object, implementation of this procedure -provides for ``string`` representation. - -.. code-block:: nim - type - Person = object - name: string - age: int - - proc `$`(p: Person): string = # `$` always returns a string - result = p.name & " is " & - $p.age & # we *need* the `$` in front of p.age, which - # is natively an integer, to convert it to - # a string - " years old." - -While ``$p.name`` can also be used, the ``$`` operation on a string does -nothing. Note that we cannot rely on automatic conversion from an ``int`` to -a ``string`` like we can for the ``echo`` proc. - -Strings are compared by their lexicographical order. All comparison operators -are available. Strings can be indexed like arrays (lower bound is 0). Unlike -arrays, they can be used in case statements: - -.. code-block:: nim - - case paramStr(i) - of "-v": incl(options, optVerbose) - of "-h", "-?": incl(options, optHelp) - else: write(stdout, "invalid command line option!\n") - -Per convention, all strings are UTF-8 strings, but this is not enforced. For -example, when reading strings from binary files, they are merely a sequence of -bytes. The index operation ``s[i]`` means the i-th *char* of ``s``, not the -i-th *unichar*. The iterator ``runes`` from the `unicode module -`_ can be used for iteration over all Unicode characters. - - -cstring type ------------- - -The ``cstring`` type meaning `compatible string` is the native representation -of a string for the compilation backend. For the C backend the ``cstring`` type -represents a pointer to a zero-terminated char array -compatible to the type ``char*`` in Ansi C. Its primary purpose lies in easy -interfacing with C. The index operation ``s[i]`` means the i-th *char* of -``s``; however no bounds checking for ``cstring`` is performed making the -index operation unsafe. - -A Nim ``string`` is implicitly convertible -to ``cstring`` for convenience. If a Nim string is passed to a C-style -variadic proc, it is implicitly converted to ``cstring`` too: - -.. code-block:: nim - proc printf(formatstr: cstring) {.importc: "printf", varargs, - header: "".} - - printf("This works %s", "as expected") - -Even though the conversion is implicit, it is not *safe*: The garbage collector -does not consider a ``cstring`` to be a root and may collect the underlying -memory. However in practice this almost never happens as the GC considers -stack roots conservatively. One can use the builtin procs ``GC_ref`` and -``GC_unref`` to keep the string data alive for the rare cases where it does -not work. - -A `$` proc is defined for cstrings that returns a string. Thus to get a nim -string from a cstring: - -.. code-block:: nim - var str: string = "Hello!" - var cstr: cstring = str - var newstr: string = $cstr - -Structured types ----------------- -A variable of a structured type can hold multiple values at the same -time. Structured types can be nested to unlimited levels. Arrays, sequences, -tuples, objects and sets belong to the structured types. - -Array and sequence types ------------------------- -Arrays are a homogeneous type, meaning that each element in the array -has the same type. Arrays always have a fixed length which is specified at -compile time (except for open arrays). They can be indexed by any ordinal type. -A parameter ``A`` may be an *open array*, in which case it is indexed by -integers from 0 to ``len(A)-1``. An array expression may be constructed by the -array constructor ``[]``. The element type of this array expression is -inferred from the type of the first element. All other elements need to be -implicitly convertable to this type. - -Sequences are similar to arrays but of dynamic length which may change -during runtime (like strings). Sequences are implemented as growable arrays, -allocating pieces of memory as items are added. A sequence ``S`` is always -indexed by integers from 0 to ``len(S)-1`` and its bounds are checked. -Sequences can be constructed by the array constructor ``[]`` in conjunction -with the array to sequence operator ``@``. Another way to allocate space for a -sequence is to call the built-in ``newSeq`` procedure. - -A sequence may be passed to a parameter that is of type *open array*. - -Example: - -.. code-block:: nim - - type - IntArray = array[0..5, int] # an array that is indexed with 0..5 - IntSeq = seq[int] # a sequence of integers - var - x: IntArray - y: IntSeq - x = [1, 2, 3, 4, 5, 6] # [] is the array constructor - y = @[1, 2, 3, 4, 5, 6] # the @ turns the array into a sequence - - let z = [1.0, 2, 3, 4] # the type of z is array[0..3, float] - -The lower bound of an array or sequence may be received by the built-in proc -``low()``, the higher bound by ``high()``. The length may be -received by ``len()``. ``low()`` for a sequence or an open array always returns -0, as this is the first valid index. -One can append elements to a sequence with the ``add()`` proc or the ``&`` -operator, and remove (and get) the last element of a sequence with the -``pop()`` proc. - -The notation ``x[i]`` can be used to access the i-th element of ``x``. - -Arrays are always bounds checked (at compile-time or at runtime). These -checks can be disabled via pragmas or invoking the compiler with the -``--boundChecks:off`` command line switch. - - -Open arrays ------------ - -Often fixed size arrays turn out to be too inflexible; procedures should -be able to deal with arrays of different sizes. The `openarray`:idx: type -allows this; it can only be used for parameters. Openarrays are always -indexed with an ``int`` starting at position 0. The ``len``, ``low`` -and ``high`` operations are available for open arrays too. Any array with -a compatible base type can be passed to an openarray parameter, the index -type does not matter. In addition to arrays sequences can also be passed -to an open array parameter. - -The openarray type cannot be nested: multidimensional openarrays are not -supported because this is seldom needed and cannot be done efficiently. - -.. code-block:: nim - proc testOpenArray(x: openArray[int]) = echo repr(x) - - testOpenArray([1,2,3]) # array[] - testOpenArray(@[1,2,3]) # seq[] - -Varargs -------- - -A ``varargs`` parameter is an openarray parameter that additionally -allows to pass a variable number of arguments to a procedure. The compiler -converts the list of arguments to an array implicitly: - -.. code-block:: nim - proc myWriteln(f: File, a: varargs[string]) = - for s in items(a): - write(f, s) - write(f, "\n") - - myWriteln(stdout, "abc", "def", "xyz") - # is transformed to: - myWriteln(stdout, ["abc", "def", "xyz"]) - -This transformation is only done if the varargs parameter is the -last parameter in the procedure header. It is also possible to perform -type conversions in this context: - -.. code-block:: nim - proc myWriteln(f: File, a: varargs[string, `$`]) = - for s in items(a): - write(f, s) - write(f, "\n") - - myWriteln(stdout, 123, "abc", 4.0) - # is transformed to: - myWriteln(stdout, [$123, $"def", $4.0]) - -In this example ``$`` is applied to any argument that is passed to the -parameter ``a``. (Note that ``$`` applied to strings is a nop.) - -Note that an explicit array constructor passed to a ``varargs`` parameter is -not wrapped in another implicit array construction: - -.. code-block:: nim - proc takeV[T](a: varargs[T]) = discard - - takeV([123, 2, 1]) # takeV's T is "int", not "array of int" - - -``varargs[typed]`` is treated specially: It matches a variable list of arguments -of arbitrary type but *always* constructs an implicit array. This is required -so that the builtin ``echo`` proc does what is expected: - -.. code-block:: nim - proc echo*(x: varargs[typed, `$`]) {...} - - echo @[1, 2, 3] - # prints "@[1, 2, 3]" and not "123" - - -Tuples and object types ------------------------ -A variable of a tuple or object type is a heterogeneous storage -container. -A tuple or object defines various named *fields* of a type. A tuple also -defines an *order* of the fields. Tuples are meant for heterogeneous storage -types with no overhead and few abstraction possibilities. The constructor ``()`` -can be used to construct tuples. The order of the fields in the constructor -must match the order of the tuple's definition. Different tuple-types are -*equivalent* if they specify the same fields of the same type in the same -order. The *names* of the fields also have to be identical. - -The assignment operator for tuples copies each component. -The default assignment operator for objects copies each component. Overloading -of the assignment operator is described in `type-bound-operations-operator`_. - -.. code-block:: nim - - type - Person = tuple[name: string, age: int] # type representing a person: - # a person consists of a name - # and an age - var - person: Person - person = (name: "Peter", age: 30) - # the same, but less readable: - person = ("Peter", 30) - -The implementation aligns the fields for best access performance. The alignment -is compatible with the way the C compiler does it. - -For consistency with ``object`` declarations, tuples in a ``type`` section -can also be defined with indentation instead of ``[]``: - -.. code-block:: nim - type - Person = tuple # type representing a person - name: string # a person consists of a name - age: natural # and an age - -Objects provide many features that tuples do not. Object provide inheritance -and information hiding. Objects have access to their type at runtime, so that -the ``of`` operator can be used to determine the object's type. The ``of`` operator -is similar to the ``instanceof`` operator in Java. - -.. code-block:: nim - type - Person = object of RootObj - name*: string # the * means that `name` is accessible from other modules - age: int # no * means that the field is hidden - - Student = ref object of Person # a student is a person - id: int # with an id field - - var - student: Student - person: Person - assert(student of Student) # is true - assert(student of Person) # also true - -Object fields that should be visible from outside the defining module, have to -be marked by ``*``. In contrast to tuples, different object types are -never *equivalent*. Objects that have no ancestor are implicitly ``final`` -and thus have no hidden type field. One can use the ``inheritable`` pragma to -introduce new object roots apart from ``system.RootObj``. - - -Object construction -------------------- - -Objects can also be created with an `object construction expression`:idx: that -has the syntax ``T(fieldA: valueA, fieldB: valueB, ...)`` where ``T`` is -an ``object`` type or a ``ref object`` type: - -.. code-block:: nim - var student = Student(name: "Anton", age: 5, id: 3) - -Note that, unlike tuples, objects require the field names along with their values. -For a ``ref object`` type ``system.new`` is invoked implicitly. - - -Object variants ---------------- -Often an object hierarchy is overkill in certain situations where simple -variant types are needed. - -An example: - -.. code-block:: nim - - # This is an example how an abstract syntax tree could be modelled in Nim - type - NodeKind = enum # the different node types - nkInt, # a leaf with an integer value - nkFloat, # a leaf with a float value - nkString, # a leaf with a string value - nkAdd, # an addition - nkSub, # a subtraction - nkIf # an if statement - Node = ref NodeObj - NodeObj = object - case kind: NodeKind # the ``kind`` field is the discriminator - of nkInt: intVal: int - of nkFloat: floatVal: float - of nkString: strVal: string - of nkAdd, nkSub: - leftOp, rightOp: Node - of nkIf: - condition, thenPart, elsePart: Node - - # create a new case object: - var n = Node(kind: nkIf, condition: nil) - # accessing n.thenPart is valid because the ``nkIf`` branch is active: - n.thenPart = Node(kind: nkFloat, floatVal: 2.0) - - # the following statement raises an `FieldError` exception, because - # n.kind's value does not fit and the ``nkString`` branch is not active: - n.strVal = "" - - # invalid: would change the active object branch: - n.kind = nkInt - - var x = Node(kind: nkAdd, leftOp: Node(kind: nkInt, intVal: 4), - rightOp: Node(kind: nkInt, intVal: 2)) - # valid: does not change the active object branch: - x.kind = nkSub - -As can been seen from the example, an advantage to an object hierarchy is that -no casting between different object types is needed. Yet, access to invalid -object fields raises an exception. - -The syntax of ``case`` in an object declaration follows closely the syntax of -the ``case`` statement: The branches in a ``case`` section may be indented too. - -In the example the ``kind`` field is called the `discriminator`:idx:\: For -safety its address cannot be taken and assignments to it are restricted: The -new value must not lead to a change of the active object branch. For an object -branch switch ``system.reset`` has to be used. Also, when the fields of a -particular branch are specified during object construction, the correct value -for the discriminator must be supplied at compile-time. - -Package level objects ---------------------- - -Every Nim module resides in a (nimble) package. An object type can be attached -to the package it resides in. If that is done, the type can be referenced from -other modules as an `incomplete`:idx: object type. This features allows to -break up recursive type dependencies accross module boundaries. Incomplete -object types are always passed ``byref`` and can only be used in pointer like -contexts (``var/ref/ptr IncompleteObject``) in general since the compiler does -not yet know the size of the object. To complete an incomplete object -the ``package`` pragma has to be used. ``package`` implies ``byref``. - -As long as a type ``T`` is incomplete ``sizeof(T)`` or "runtime type -information" for ``T`` is not available. - - -Example: - -.. code-block:: nim - - # module A (in an arbitrary package) - type - Pack.SomeObject = object ## declare as incomplete object of package 'Pack' - Triple = object - a, b, c: ref SomeObject ## pointers to incomplete objects are allowed - - ## Incomplete objects can be used as parameters: - proc myproc(x: SomeObject) = discard - - -.. code-block:: nim - - # module B (in package "Pack") - type - SomeObject* {.package.} = object ## Use 'package' to complete the object - s, t: string - x, y: int - - -Set type --------- - -.. include:: ../sets_fragment.txt - -Reference and pointer types ---------------------------- -References (similar to pointers in other programming languages) are a -way to introduce many-to-one relationships. This means different references can -point to and modify the same location in memory (also called `aliasing`:idx:). - -Nim distinguishes between `traced`:idx: and `untraced`:idx: references. -Untraced references are also called *pointers*. Traced references point to -objects of a garbage collected heap, untraced references point to -manually allocated objects or to objects somewhere else in memory. Thus -untraced references are *unsafe*. However for certain low-level operations -(accessing the hardware) untraced references are unavoidable. - -Traced references are declared with the **ref** keyword, untraced references -are declared with the **ptr** keyword. In general, a `ptr T` is implicitly -convertible to the `pointer` type. - -An empty subscript ``[]`` notation can be used to derefer a reference, -the ``addr`` procedure returns the address of an item. An address is always -an untraced reference. -Thus the usage of ``addr`` is an *unsafe* feature. - -The ``.`` (access a tuple/object field operator) -and ``[]`` (array/string/sequence index operator) operators perform implicit -dereferencing operations for reference types: - -.. code-block:: nim - - type - Node = ref NodeObj - NodeObj = object - le, ri: Node - data: int - - var - n: Node - new(n) - n.data = 9 - # no need to write n[].data; in fact n[].data is highly discouraged! - -Automatic dereferencing is also performed for the first argument of a routine -call. But currently this feature has to be only enabled -via ``{.experimental.}``: - -.. code-block:: nim - {.experimental.} - - proc depth(x: NodeObj): int = ... - - var - n: Node - new(n) - echo n.depth - # no need to write n[].depth either - - - -In order to simplify structural type checking, recursive tuples are not valid: - -.. code-block:: nim - # invalid recursion - type MyTuple = tuple[a: ref MyTuple] - -Likewise ``T = ref T`` is an invalid type. - -As a syntactical extension ``object`` types can be anonymous if -declared in a type section via the ``ref object`` or ``ptr object`` notations. -This feature is useful if an object should only gain reference semantics: - -.. code-block:: nim - - type - Node = ref object - le, ri: Node - data: int - - -To allocate a new traced object, the built-in procedure ``new`` has to be used. -To deal with untraced memory, the procedures ``alloc``, ``dealloc`` and -``realloc`` can be used. The documentation of the system module contains -further information. - -If a reference points to *nothing*, it has the value ``nil``. - -Special care has to be taken if an untraced object contains traced objects like -traced references, strings or sequences: in order to free everything properly, -the built-in procedure ``GCunref`` has to be called before freeing the untraced -memory manually: - -.. code-block:: nim - type - Data = tuple[x, y: int, s: string] - - # allocate memory for Data on the heap: - var d = cast[ptr Data](alloc0(sizeof(Data))) - - # create a new string on the garbage collected heap: - d.s = "abc" - - # tell the GC that the string is not needed anymore: - GCunref(d.s) - - # free the memory: - dealloc(d) - -Without the ``GCunref`` call the memory allocated for the ``d.s`` string would -never be freed. The example also demonstrates two important features for low -level programming: the ``sizeof`` proc returns the size of a type or value -in bytes. The ``cast`` operator can circumvent the type system: the compiler -is forced to treat the result of the ``alloc0`` call (which returns an untyped -pointer) as if it would have the type ``ptr Data``. Casting should only be -done if it is unavoidable: it breaks type safety and bugs can lead to -mysterious crashes. - -**Note**: The example only works because the memory is initialized to zero -(``alloc0`` instead of ``alloc`` does this): ``d.s`` is thus initialized to -``nil`` which the string assignment can handle. One needs to know low level -details like this when mixing garbage collected data with unmanaged memory. - -.. XXX finalizers for traced objects - - -Not nil annotation ------------------- - -All types for that ``nil`` is a valid value can be annotated to -exclude ``nil`` as a valid value with the ``not nil`` annotation: - -.. code-block:: nim - type - PObject = ref TObj not nil - TProc = (proc (x, y: int)) not nil - - proc p(x: PObject) = - echo "not nil" - - # compiler catches this: - p(nil) - - # and also this: - var x: PObject - p(x) - -The compiler ensures that every code path initializes variables which contain -non nilable pointers. The details of this analysis are still to be specified -here. - - -Memory regions --------------- - -The types ``ref`` and ``ptr`` can get an optional ``region`` annotation. -A region has to be an object type. - -Regions are very useful to separate user space and kernel memory in the -development of OS kernels: - -.. code-block:: nim - type - Kernel = object - Userspace = object - - var a: Kernel ptr Stat - var b: Userspace ptr Stat - - # the following does not compile as the pointer types are incompatible: - a = b - -As the example shows ``ptr`` can also be used as a binary -operator, ``region ptr T`` is a shortcut for ``ptr[region, T]``. - -In order to make generic code easier to write ``ptr T`` is a subtype -of ``ptr[R, T]`` for any ``R``. - -Furthermore the subtype relation of the region object types is lifted to -the pointer types: If ``A <: B`` then ``ptr[A, T] <: ptr[B, T]``. This can be -used to model subregions of memory. As a special typing rule ``ptr[R, T]`` is -not compatible to ``pointer`` to prevent the following from compiling: - -.. code-block:: nim - # from system - proc dealloc(p: pointer) - - # wrap some scripting language - type - PythonsHeap = object - PyObjectHeader = object - rc: int - typ: pointer - PyObject = ptr[PythonsHeap, PyObjectHeader] - - proc createPyObject(): PyObject {.importc: "...".} - proc destroyPyObject(x: PyObject) {.importc: "...".} - - var foo = createPyObject() - # type error here, how convenient: - dealloc(foo) - - -Future directions: - -* Memory regions might become available for ``string`` and ``seq`` too. -* Builtin regions like ``private``, ``global`` and ``local`` might be - useful for an OpenCL target. -* Builtin "regions" can model ``lent`` and ``unique`` pointers. -* An assignment operator can be attached to a region so that proper write - barriers can be generated. This would imply that the GC can be implemented - completely in user-space. - - -Procedural type ---------------- -A procedural type is internally a pointer to a procedure. ``nil`` is -an allowed value for variables of a procedural type. Nim uses procedural -types to achieve `functional`:idx: programming techniques. - -Examples: - -.. code-block:: nim - - proc printItem(x: int) = ... - - proc forEach(c: proc (x: int) {.cdecl.}) = - ... - - forEach(printItem) # this will NOT compile because calling conventions differ - - -.. code-block:: nim - - type - OnMouseMove = proc (x, y: int) {.closure.} - - proc onMouseMove(mouseX, mouseY: int) = - # has default calling convention - echo "x: ", mouseX, " y: ", mouseY - - proc setOnMouseMove(mouseMoveEvent: OnMouseMove) = discard - - # ok, 'onMouseMove' has the default calling convention, which is compatible - # to 'closure': - setOnMouseMove(onMouseMove) - - -A subtle issue with procedural types is that the calling convention of the -procedure influences the type compatibility: procedural types are only -compatible if they have the same calling convention. As a special extension, -a procedure of the calling convention ``nimcall`` can be passed to a parameter -that expects a proc of the calling convention ``closure``. - -Nim supports these `calling conventions`:idx:\: - -`nimcall`:idx: - is the default convention used for a Nim **proc**. It is the - same as ``fastcall``, but only for C compilers that support ``fastcall``. - -`closure`:idx: - is the default calling convention for a **procedural type** that lacks - any pragma annotations. It indicates that the procedure has a hidden - implicit parameter (an *environment*). Proc vars that have the calling - convention ``closure`` take up two machine words: One for the proc pointer - and another one for the pointer to implicitly passed environment. - -`stdcall`:idx: - This the stdcall convention as specified by Microsoft. The generated C - procedure is declared with the ``__stdcall`` keyword. - -`cdecl`:idx: - The cdecl convention means that a procedure shall use the same convention - as the C compiler. Under windows the generated C procedure is declared with - the ``__cdecl`` keyword. - -`safecall`:idx: - This is the safecall convention as specified by Microsoft. The generated C - procedure is declared with the ``__safecall`` keyword. The word *safe* - refers to the fact that all hardware registers shall be pushed to the - hardware stack. - -`inline`:idx: - The inline convention means the the caller should not call the procedure, - but inline its code directly. Note that Nim does not inline, but leaves - this to the C compiler; it generates ``__inline`` procedures. This is - only a hint for the compiler: it may completely ignore it and - it may inline procedures that are not marked as ``inline``. - -`fastcall`:idx: - Fastcall means different things to different C compilers. One gets whatever - the C ``__fastcall`` means. - -`syscall`:idx: - The syscall convention is the same as ``__syscall`` in C. It is used for - interrupts. - -`noconv`:idx: - The generated C code will not have any explicit calling convention and thus - use the C compiler's default calling convention. This is needed because - Nim's default calling convention for procedures is ``fastcall`` to - improve speed. - -Most calling conventions exist only for the Windows 32-bit platform. - -The default calling convention is ``nimcall``, unless it is an inner proc (a -proc inside of a proc). For an inner proc an analysis is performed whether it -accesses its environment. If it does so, it has the calling convention -``closure``, otherwise it has the calling convention ``nimcall``. - - -Distinct type -------------- - -A ``distinct`` type is new type derived from a `base type`:idx: that is -incompatible with its base type. In particular, it is an essential property -of a distinct type that it **does not** imply a subtype relation between it -and its base type. Explicit type conversions from a distinct type to its -base type and vice versa are allowed. - - -Modelling currencies -~~~~~~~~~~~~~~~~~~~~ - -A distinct type can be used to model different physical `units`:idx: with a -numerical base type, for example. The following example models currencies. - -Different currencies should not be mixed in monetary calculations. Distinct -types are a perfect tool to model different currencies: - -.. code-block:: nim - type - Dollar = distinct int - Euro = distinct int - - var - d: Dollar - e: Euro - - echo d + 12 - # Error: cannot add a number with no unit and a ``Dollar`` - -Unfortunately, ``d + 12.Dollar`` is not allowed either, -because ``+`` is defined for ``int`` (among others), not for ``Dollar``. So -a ``+`` for dollars needs to be defined: - -.. code-block:: - proc `+` (x, y: Dollar): Dollar = - result = Dollar(int(x) + int(y)) - -It does not make sense to multiply a dollar with a dollar, but with a -number without unit; and the same holds for division: - -.. code-block:: - proc `*` (x: Dollar, y: int): Dollar = - result = Dollar(int(x) * y) - - proc `*` (x: int, y: Dollar): Dollar = - result = Dollar(x * int(y)) - - proc `div` ... - -This quickly gets tedious. The implementations are trivial and the compiler -should not generate all this code only to optimize it away later - after all -``+`` for dollars should produce the same binary code as ``+`` for ints. -The pragma `borrow`:idx: has been designed to solve this problem; in principle -it generates the above trivial implementations: - -.. code-block:: nim - proc `*` (x: Dollar, y: int): Dollar {.borrow.} - proc `*` (x: int, y: Dollar): Dollar {.borrow.} - proc `div` (x: Dollar, y: int): Dollar {.borrow.} - -The ``borrow`` pragma makes the compiler use the same implementation as -the proc that deals with the distinct type's base type, so no code is -generated. - -But it seems all this boilerplate code needs to be repeated for the ``Euro`` -currency. This can be solved with templates_. - -.. code-block:: nim - template additive(typ: typedesc) = - proc `+` *(x, y: typ): typ {.borrow.} - proc `-` *(x, y: typ): typ {.borrow.} - - # unary operators: - proc `+` *(x: typ): typ {.borrow.} - proc `-` *(x: typ): typ {.borrow.} - - template multiplicative(typ, base: typedesc) = - proc `*` *(x: typ, y: base): typ {.borrow.} - proc `*` *(x: base, y: typ): typ {.borrow.} - proc `div` *(x: typ, y: base): typ {.borrow.} - proc `mod` *(x: typ, y: base): typ {.borrow.} - - template comparable(typ: typedesc) = - proc `<` * (x, y: typ): bool {.borrow.} - proc `<=` * (x, y: typ): bool {.borrow.} - proc `==` * (x, y: typ): bool {.borrow.} - - template defineCurrency(typ, base: untyped) = - type - typ* = distinct base - additive(typ) - multiplicative(typ, base) - comparable(typ) - - defineCurrency(Dollar, int) - defineCurrency(Euro, int) - - -The borrow pragma can also be used to annotate the distinct type to allow -certain builtin operations to be lifted: - -.. code-block:: nim - type - Foo = object - a, b: int - s: string - - Bar {.borrow: `.`.} = distinct Foo - - var bb: ref Bar - new bb - # field access now valid - bb.a = 90 - bb.s = "abc" - -Currently only the dot accessor can be borrowed in this way. - - -Avoiding SQL injection attacks -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -An SQL statement that is passed from Nim to an SQL database might be -modelled as a string. However, using string templates and filling in the -values is vulnerable to the famous `SQL injection attack`:idx:\: - -.. code-block:: nim - import strutils - - proc query(db: DbHandle, statement: string) = ... - - var - username: string - - db.query("SELECT FROM users WHERE name = '$1'" % username) - # Horrible security hole, but the compiler does not mind! - -This can be avoided by distinguishing strings that contain SQL from strings -that don't. Distinct types provide a means to introduce a new string type -``SQL`` that is incompatible with ``string``: - -.. code-block:: nim - type - SQL = distinct string - - proc query(db: DbHandle, statement: SQL) = ... - - var - username: string - - db.query("SELECT FROM users WHERE name = '$1'" % username) - # Error at compile time: `query` expects an SQL string! - - -It is an essential property of abstract types that they **do not** imply a -subtype relation between the abstract type and its base type. Explicit type -conversions from ``string`` to ``SQL`` are allowed: - -.. code-block:: nim - import strutils, sequtils - - proc properQuote(s: string): SQL = - # quotes a string properly for an SQL statement - return SQL(s) - - proc `%` (frmt: SQL, values: openarray[string]): SQL = - # quote each argument: - let v = values.mapIt(SQL, properQuote(it)) - # we need a temporary type for the type conversion :-( - type StrSeq = seq[string] - # call strutils.`%`: - result = SQL(string(frmt) % StrSeq(v)) - - db.query("SELECT FROM users WHERE name = '$1'".SQL % [username]) - -Now we have compile-time checking against SQL injection attacks. Since -``"".SQL`` is transformed to ``SQL("")`` no new syntax is needed for nice -looking ``SQL`` string literals. The hypothetical ``SQL`` type actually -exists in the library as the `TSqlQuery type `_ of -modules like `db_sqlite `_. - - -Void type ---------- - -The ``void`` type denotes the absence of any type. Parameters of -type ``void`` are treated as non-existent, ``void`` as a return type means that -the procedure does not return a value: - -.. code-block:: nim - proc nothing(x, y: void): void = - echo "ha" - - nothing() # writes "ha" to stdout - -The ``void`` type is particularly useful for generic code: - -.. code-block:: nim - proc callProc[T](p: proc (x: T), x: T) = - when T is void: - p() - else: - p(x) - - proc intProc(x: int) = discard - proc emptyProc() = discard - - callProc[int](intProc, 12) - callProc[void](emptyProc) - -However, a ``void`` type cannot be inferred in generic code: - -.. code-block:: nim - callProc(emptyProc) - # Error: type mismatch: got (proc ()) - # but expected one of: - # callProc(p: proc (T), x: T) - -The ``void`` type is only valid for parameters and return types; other symbols -cannot have the type ``void``. - - -Auto type ---------- - -The ``auto`` type can only be used for return types and parameters. For return -types it causes the compiler to infer the type from the routine body: - -.. code-block:: nim - proc returnsInt(): auto = 1984 - -For parameters it currently creates implicitly generic routines: - -.. code-block:: nim - proc foo(a, b: auto) = discard - -Is the same as: - -.. code-block:: nim - proc foo[T1, T2](a: T1, b: T2) = discard - -However later versions of the language might change this to mean "infer the -parameters' types from the body". Then the above ``foo`` would be rejected as -the parameters' types can not be inferred from an empty ``discard`` statement.

This allows you to pass a template or a macro to another macro which can then inspect the implementation of the former template/macro using `getImpl`. Since templates can be freely redefined, this allows you to treat their symbols as compile-time variables that have lexical scope. A motivating PoC example for a logging library taking advantage of this will be provided in the next commit. Implementation details: * The name of a template or a macro will be consider a symbol if the template/macro requires parameters * For parameterless templates/macros, you can use `bindSym`, which was extended to also work outside of compile-time procs. --- compiler/ast.nim | 13 +++ compiler/evaltempl.nim | 2 +- compiler/semexprs.nim | 8 +- compiler/semmagic.nim | 4 + compiler/sigmatch.nim | 8 +- lib/core/macros.nim | 2 +- tests/macros/ttemplatesymbols.nim | 173 ++++++++++++++++++++++++++++++ 7 files changed, 202 insertions(+), 8 deletions(-) create mode 100644 tests/macros/ttemplatesymbols.nim diff --git a/compiler/ast.nim b/compiler/ast.nim index b8202abe60..350fa5f6ac 100644 --- a/compiler/ast.nim +++ b/compiler/ast.nim @@ -1615,6 +1615,19 @@ proc originatingModule*(s: PSym): PSym = proc isRoutine*(s: PSym): bool {.inline.} = result = s.kind in skProcKinds +proc isCompileTimeProc*(s: PSym): bool {.inline.} = + result = s.kind == skMacro or + s.kind == skProc and sfCompileTime in s.flags + +proc requiredParams*(s: PSym): int = + # Returns the number of required params (without default values) + # XXX: Perhaps we can store this in the `offset` field of the + # symbol instead? + for i in 1 ..< s.typ.len: + if s.typ.n[i].sym.ast != nil: + return i - 1 + return s.typ.len - 1 + proc hasPattern*(s: PSym): bool {.inline.} = result = isRoutine(s) and s.ast.sons[patternPos].kind != nkEmpty diff --git a/compiler/evaltempl.nim b/compiler/evaltempl.nim index fbb7eb2e6e..5024308157 100644 --- a/compiler/evaltempl.nim +++ b/compiler/evaltempl.nim @@ -63,7 +63,7 @@ proc evalTemplateArgs(n: PNode, s: PSym; fromHlo: bool): PNode = # if the template has zero arguments, it can be called without ``()`` # `n` is then a nkSym or something similar var totalParams = case n.kind - of nkCall, nkInfix, nkPrefix, nkPostfix, nkCommand, nkCallStrLit: n.len-1 + of nkCallKinds: n.len-1 else: 0 var diff --git a/compiler/semexprs.nim b/compiler/semexprs.nim index 4a3672aa0d..29f377a190 100644 --- a/compiler/semexprs.nim +++ b/compiler/semexprs.nim @@ -960,18 +960,20 @@ proc semSym(c: PContext, n: PNode, sym: PSym, flags: TExprFlags): PNode = else: result = newSymNode(s, n.info) of skMacro: - if efNoEvaluateGeneric in flags and s.ast[genericParamsPos].len > 0: + if efNoEvaluateGeneric in flags and s.ast[genericParamsPos].len > 0 or + (n.kind notin nkCallKinds and s.requiredParams > 0): markUsed(n.info, s, c.graph.usageSym) styleCheckUse(n.info, s) - result = newSymNode(s, n.info) + result = symChoice(c, n, s, scClosed) else: result = semMacroExpr(c, n, n, s, flags) of skTemplate: if efNoEvaluateGeneric in flags and s.ast[genericParamsPos].len > 0 or + (n.kind notin nkCallKinds and s.requiredParams > 0) or sfCustomPragma in sym.flags: markUsed(n.info, s, c.graph.usageSym) styleCheckUse(n.info, s) - result = newSymNode(s, n.info) + result = symChoice(c, n, s, scClosed) else: result = semTemplateExpr(c, n, s, flags) of skParam: diff --git a/compiler/semmagic.nim b/compiler/semmagic.nim index 3f0df00650..bf3c55120f 100644 --- a/compiler/semmagic.nim +++ b/compiler/semmagic.nim @@ -199,6 +199,10 @@ proc semBindSym(c: PContext, n: PNode): PNode = if s != nil: # we need to mark all symbols: var sc = symChoice(c, id, s, TSymChoiceRule(isMixin.intVal)) + if not getCurrOwner(c).isCompileTimeProc: + # inside regular code, bindSym resolves to the sym-choice + # nodes (see tinspectsymbol) + return sc result.add(sc) else: errorUndeclaredIdentifier(c, n.sons[1].info, sl.strVal) diff --git a/compiler/sigmatch.nim b/compiler/sigmatch.nim index 4263ef5813..7e566afad6 100644 --- a/compiler/sigmatch.nim +++ b/compiler/sigmatch.nim @@ -2032,8 +2032,9 @@ proc paramTypesMatch*(m: var TCandidate, f, a: PType, y.calleeSym = m.calleeSym z.calleeSym = m.calleeSym var best = -1 - for i in countup(0, sonsLen(arg) - 1): - if arg.sons[i].sym.kind in {skProc, skFunc, skMethod, skConverter, skIterator}: + for i in 0 ..< arg.len: + if arg.sons[i].sym.kind in {skProc, skFunc, skMethod, skConverter, + skIterator, skMacro, skTemplate}: copyCandidate(z, m) z.callee = arg.sons[i].typ if tfUnresolved in z.callee.flags: continue @@ -2062,6 +2063,7 @@ proc paramTypesMatch*(m: var TCandidate, f, a: PType, x = z elif cmp == 0: y = z # z is as good as x + if x.state == csEmpty: result = nil elif y.state == csMatch and cmpCandidates(x, y) == 0: @@ -2070,7 +2072,7 @@ proc paramTypesMatch*(m: var TCandidate, f, a: PType, # ambiguous: more than one symbol fits! # See tsymchoice_for_expr as an example.

Date: Fri, 4 May 2018 19:56:03 +0300 Subject: [PATCH 0356/1122] bugfix: strutils.find was broken for strings with uneven number of chars For some reason, the problem was manifesting only inside the VM, it was detecting an attempt to read past the string end (i.e. the formerly accessible null byte). To catch such errors, strutils now performs static tests too. I've solved the problem by re-implementing the Boyer-Moore algotihm in a cleaner way and I took the opportunity to make some other optimisations to strutils. --- lib/pure/strutils.nim | 454 +++++++++++++++++++++++------------------- 1 file changed, 245 insertions(+), 209 deletions(-) diff --git a/lib/pure/strutils.nim b/lib/pure/strutils.nim index 3f01f02853..ee3072c855 100644 --- a/lib/pure/strutils.nim +++ b/lib/pure/strutils.nim @@ -1262,21 +1262,20 @@ proc initSkipTable*(a: var SkipTable, sub: string) {.noSideEffect, rtl, extern: "nsuInitSkipTable".} = ## Preprocess table `a` for `sub`. let m = len(sub) - let m1 = m + 1 var i = 0 while i <= 0xff-7: - a[chr(i + 0)] = m1 - a[chr(i + 1)] = m1 - a[chr(i + 2)] = m1 - a[chr(i + 3)] = m1 - a[chr(i + 4)] = m1 - a[chr(i + 5)] = m1 - a[chr(i + 6)] = m1 - a[chr(i + 7)] = m1 + a[chr(i + 0)] = m + a[chr(i + 1)] = m + a[chr(i + 2)] = m + a[chr(i + 3)] = m + a[chr(i + 4)] = m + a[chr(i + 5)] = m + a[chr(i + 6)] = m + a[chr(i + 7)] = m i += 8 - for i in 0..m-1: - a[sub[i]] = m-i + for i in 0 ..< m - 1: + a[sub[i]] = m - 1 - i proc find*(a: SkipTable, s, sub: string, start: Natural = 0, last: Natural = 0): int {.noSideEffect, rtl, extern: "nsuFindStrA".} = @@ -1284,18 +1283,29 @@ proc find*(a: SkipTable, s, sub: string, start: Natural = 0, last: Natural = 0): ## If `last` is unspecified, it defaults to `s.high`. ## ## Searching is case-sensitive.
