6505bd347d Markdown indented code blocks (#20473)
* Implement Markdown indented code blocks

Additional indentation of 4 spaces makes a block an "indented code block"
(monospaced text without syntax highlighting).
Also `::` RST syntax for code blocks is disabled.

So instead of
```rst
see::

  Some code
```

the code block should be written as
```markdown
see:

    Some code
```

10355cb48a strutils, rstgen: avoid deprecated strutils.delete (#20488)
The strutils `delete` func with signature

    func delete*(s: var string, first, last: int)

was deprecated in adba5eb45e, in favor of one with signature

    func delete*(s: var string, slice: Slice[int])

However, a few procedures still used the deprecated form. This commit
updates them, resolving these deprecation warnings:

    rstgen.nim(766, 12) Warning: use `delete(s, first..last)`; delete is deprecated [Deprecated]
    strutils.nim(1651, 19) Warning: use `delete(s, first..last)`; delete is deprecated [Deprecated]
    strutils.nim(1679, 7) Warning: use `delete(s, first..last)`; delete is deprecated [Deprecated]
    strutils.nim(2472, 7) Warning: use `delete(s, first..last)`; delete is deprecated [Deprecated]

Before this commit:

- `trimZeros` called `s.delete(i+1, i)` for an input that lacks a
  trailing zero (like "1.23").

- `removePrefix*(s: var string, prefix: string)` called
  `s.delete(0, -1)` when the prefix was the empty string.

which did not modify `s`, nor raise an error. But the newer slice
`delete` raises an `IndexDefect` when the start of the slice is greater
than the end, so we avoid calling the new `delete` for such a case.

Recall that exceptions inheriting from `system.Defect` are not tracked
with the `.raises: []` exception tracking mechanism [1], so this commit
does not break existing code like:

    proc foo {.raises: [].} =
      var s = "abc1.20"
      s.removePrefix("abc")
      s.trimZeros()
      doAssert s == "1.2"

The `strutils.delete` deprecation was motivated by a problem with
`system.delete` [2][3]:

    `system.delete` had surprising behavior when the index passed to it
    was out of bounds (it would delete the last entry then). Compile
    with `-d:nimStrictDelete` so that an index error is produced
    instead.

    Be aware however that your code might depend on this quirky behavior
    so a review process is required on your part before you can use
    `-d:nimStrictDelete`. To make this review easier, use the
    `-d:nimAuditDelete` switch, which pretends that `system.delete` is
    deprecated so that it is easier to see where it was used in your
    code.

    `-d:nimStrictDelete` will become the default in upcoming versions.

A similar deprecation happened with `sequtils.delete` [4], but that
deprecated form is already not used in this repo.

68f92af17c Fix cannot create Windows directory in root (#20311)
* Fix cannot create Windows directory in root

Fixes #20306, a regression bug with `createDir` caused by
`23e0160af283bb0bb573a86145e6c1c792780d49`.

The issue is that, if the path consists only of a drive and a single
directory (e.g. "Y:\nimcache2" in the original issue), then no
directories will be created. This works fine if there are multiple
directories (e.g. "Y:\nimcache2\test").

In the case of "Y:\nimcache2", `omitNext` in `createDir` is `false` on
the last condition in `createDir`. This means that the "nimcache2"
directory will not be created, and no exception will be raised.

Fixed by refactoring to use `parentDirs` iterator instead of iterating
over the string characters. Motivation is reduced code complexity.

Will not test the specific "C:\test" `createDir` case, since there is no
standard Windows drive with write permissions in the root. Creating a
custom drive-mapping to Windows Temp is a non-option. That could mess
up some users running the test.

Added `parentDirs` tests since they are lacking on for POSIX paths.

* Fix `createDir("")` causing error

The change to `createDir` caused `createDir("")` to raise an error,
where it previously didn't. Fixed so `createDir("")` does not fail, and
added test case.

cde6b2aab8 Implement Pandoc Markdown concise link extension (#20304)
* Implement Pandoc Markdown concise link extension

This implements https://github.com/nim-lang/Nim/issues/20127.
Besides reference to headings we also support doing references
to Nim symbols inside Nim modules.

Markdown:
```
Some heading
------------

Ref. [Some heading].
```

Nim:
```
proc someFunction*() ...

... ## Ref. [someFunction]
```

This is substitution for RST syntax like `` `target`_ ``.
All 3 syntax variants of extension from Pandoc Markdown are supported:
`[target]`, `[target][]`, `[description][target]`.

This PR also fixes clashes in existing files, particularly
conflicts with RST footnote feature, which does not work with
this PR (but there is a plan to adopt a popular [Markdown footnote
extension](https://pandoc.org/MANUAL.html#footnotes) to make footnotes work).

Also the PR fixes a bug that Markdown links did not work when `[...]`
section had a line break.

The implementation is straightforward since link resolution did not
change w.r.t. RST implementation, it's almost only about new syntax
addition. The only essential difference is a possibility to add a custom
link description: form `[description][target]` which does not have an
RST equivalent.

23e0160af2 Add improved Windows UNC path support in std/os (#20281)
* Add improved Windows UNC path support in std/os

Original issue: `std/os.createDir` tries to create every component of
the given path as a directory. The problem is that `createDir`
interprets every backslash/slash as a path separator. For a UNC path
this is incorrect. E.g. one UNC form is `\\Server\Volume\Path`. It's an
error to create the `\\Server` directory, as well as creating
`\\Server\Volume`.

Add `ntpath.nim` module with `splitDrive` proc. This implements UNC path
parsing as implemented in the Python `ntpath.py` module. The following
UNC forms are supported:

* `\\Server\Volume\Path`
* `\\?\Volume\Path`
* `\\?\UNC\Server\Volume\Path`

Improves support for UNC paths in various procs in `std/os`:
---

* pathnorm.addNormalizePath
  * Issue: This had incomplete support for UNC paths
    * The UNC prefix (first 2 characters of a UNC path) was assumed to
      be exactly `\\`, but it can be `//` and `\/`, etc. as well
    * Also, the UNC prefix must be normalized to the `dirSep` argument
      of `addNormalizePath`
  * Resolution: Changed to account for different UNC prefixes, and
    normalizing the prefixes according to `dirSep`
    * Affected procs that get tests: `relativePath`, `joinPath`
  * Issue: The server/volume part of UNC paths can be stripped when
    normalizing `..` path components
    * This error should be negligable, so ignoring this
* splitPath
  * Now make sure the UNC drive is not split; return the UNC drive as
    `head` if the UNC drive is the only component of the path
  * Consequently fixes `extractFilename`, `lastPathPart`
* parentDir / `/../`
  * Strip away drive before working on the path, prepending the drive
    after all work is done - prevents stripping UNC components
  * Return empty string if drive component is the only component; this
    is the behavior for POSIX paths as well
  * Alternative implementation: Just call something like
    `pathnorm.normalizePath(path & "/..")` for the whole proc - maybe
    too big of a change
* tailDir
  * If drive is present in path, just split that from path and return
    path
* parentDirs iterator
  * Uses `parentDir` for going backwards
  * When going forwards, first `splitDrive`, yield the drive field, and
    then iterate over path field as normal
* splitFile
  * Make sure path parsing stops at end of drive component
* createDir
  * Fixed by skipping drive part before creating directories
  * Alternative implementation: use `parentDirs` iterator instead of
    iterating over characters
    * Consequence is that it will try to create the root directory
* isRootDir
  * Changed to treat UNC drive alone as root (e.g. "//?/c:" is root)
  * This change prevents the empty string being yielded by the
    `parentDirs` iterator with `fromRoot = false`
* Internal `sameRoot`
  * The "root" refers to the drive, so `splitDrive` can be used here

This adds UNC path support to all procs that could use it in std/os. I
don't think any more work has to be done to support UNC paths. For the
future, I believe the path handling code can be refactored due to
duplicate code. There are multiple ways of manipulating paths, such as
manually searching string for path separator and also having a path
normalizer (pathnorm.nim). If all path manipulation used `pathnorm.nim`,
and path component splitting used `parentDirs` iterator, then a lot of
code could be removed.

Tests
---

Added test file for `pathnorm.nim` and `ntpath.nim`.
`pathnorm.normalizePath` has no tests, so I'm adding a few unit tests.
`ntpath.nim` contains tests copied from Python's test suite.

Added integration tests to `tos.nim` that tests UNC paths.

Removed incorrect `relativePath` runnableExamples from being tested on Windows:
---

`relativePath("/Users///me/bar//z.nim", "//Users/", '/') == "me/bar/z.nim"`

This is incorrect on Windows because the `/` and `//` are not the same
root. `/` (or `\`) is expanded to the drive in the current working
directory (e.g. `C:\`). `//` (or `\\`), however, are the first two
characters of a UNC path. The following holds true for normal Windows
installations:

* `dirExists("/Users") != dirExists("//Users")`
* `dirExists("\\Users") != dirExists("\\\\Users")`

Fixes #19103

Questions:
---

* Should the `splitDrive` proc be in `os.nim` instead with copyright
  notice above the proc?
* Is it fine to put most of the new tests into the `runnableExamples`
  section of the procs in std/os?

Co-authored-by: Clay Sweetser <Varriount@users.noreply.github.com>

* Move runnableExamples tests in os.nim to tos.nim

* tests/topt_no_cursor: Change from using splitFile to splitDrive

`splitFile` can no longer be used in the test, because it generates
different ARC code on Windows and Linux. This replaces `splitFile` with
`splitDrive`, because it generates same ARC code on Windows and Linux,
and returns a tuple. I assume the test wants a proc that returns a
tuple.

f4bbf3bf0b Add use of Windows Wide CRT API for env. vars (#20084)
* Add use of Windows Wide CRT API for env. vars

Replaces use of CRT API `getenv` and `putenv` with respectively
`_wgetenv` and `_wputenv`. Motivation is to reliably convert environment
variables to UTF-8, and the wide API is best there, because it's
reliably UTF-16.

Changed the hack in `lib/std/private/win_setenv.nim` by switching the
order of the Unicode and MBCS environment update; Unicode first, MBCS
second. Because `_wgetenv`/`_wputenv` is now used, the Unicode
environment will be initialized, so it should always be updated.

Stop updating MBCS environment with the name of `getEnv`. It's not
necessarily true that MBCS encoding and the `string` encoding is the
same. Instead convert UTF-16 to current Windows code page with
`wcstombs`, and use that string to update MBCS.

Fixes regression in `6b3c77e` that caused `std/envvars.getEnv` or
`std/os.getEnv` on Windows to return non-UTF-8 encoded strings.

Add tests that test environment variables with Unicode characters in
their name or value.

* Fix test issues

Fixes

* `nim cpp` didn't compile the tests
* Nimscript import of `tosenv.nim` from `test_nimscript.nims` failed
  with "cannot importc"

* Fix missing error check on `wcstombs`

* Fix ANSI testing errors

* Separate ANSI-related testing to their own tests, and only executing
  them if running process has a specific code page
  * Setting locale with `setlocale` was not reliable and didn't work on
    certain machines
* Add handling of a "no character representation" error in second
  `wcstombs` call

* tests/newruntime_misc: Increment allocCount

Increments overall allocations in `tnewruntime_misc` test. This is
because `getEnv` now does an additional allocation: allocation of the
UTF-16 string used as parameter to `c_wgetenv`.

* Revert "tests/newruntime_misc: Increment allocCount"

This reverts commit 4d4fe8bd3e.

* tests/newruntime_misc: Increment allocCount on Windows

Increments overall allocations in `tnewruntime_misc` test for Windows.
This is because `getEnv` on Windows now does an additional allocation:

e8657c7107 make implicit cstring conversions explicit (#19488)
The Nim manual says that an implicit conversion to cstring will
eventually not be allowed [1]:

    A Nim `string` is implicitly convertible to `cstring` for convenience.

    [...]

    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. For this reason, the implicit conversion will be removed in future
    releases of the Nim compiler. Certain idioms like conversion of a `const` string
    to `cstring` are safe and will remain to be allowed.

And from Nim 1.6.0, such a conversion triggers a warning [2]:

    A dangerous implicit conversion to `cstring` now triggers a `[CStringConv]` warning.
    This warning will become an error in future versions! Use an explicit conversion
    like `cstring(x)` in order to silence the warning.

However, some files in this repo produced such a warning. For example,
before this commit, compiling `parsejson.nim` would produce:

    /foo/Nim/lib/pure/parsejson.nim(221, 37) Warning: implicit conversion to 'cstring' from a non-const location: my.buf; this will become a compile time error in the future [CStringConv]
    /foo/Nim/lib/pure/parsejson.nim(231, 39) Warning: implicit conversion to 'cstring' from a non-const location: my.buf; this will become a compile time error in the future [CStringConv]

This commit resolves the most visible `CStringConv` warnings, making the
cstring conversions explicit.

c579243e0c Pass check condition directly to if (#20217)
When checking conditions, pass `check` untyped argument directly to if. This results in better error messages when the condition is malformed.

Previously `check 1` would fail at compile time with `Error: type mismatch: got 'int literal(-2)' for '-2' but expected 'bool'`
Now it fails with `Error: type mismatch: got 'int literal(1)' for '1' but expected 'bool'`.

Similarly `check "foo"` would fail with
```
Error: type mismatch: got <string>
but expected one of:
proc `not`(a: typedesc): typedesc
  first type mismatch at position: 1
  required type for a: typedesc
  but expression '"somestring"' is of type: string
...
```
Now it fails with `Error: type mismatch: got 'string' for '"somestring"' but expected 'bool'`

31b7a25e1e fix broken runnableExamples for getWeeksInIsoYear (#20193)
Based on what I understand from [Wikipedia](https://en.wikipedia.org/wiki/ISO_week_date#Weeks_per_year), 2001 does not have 53 weeks, but 2004, 2009, 2015, 2020 do. The years 2000 and 2001 seem to be copy pasted from the `getDaysInYear` example above. The result of `getWeeksInIsoYear` also seem to match up with Wikipedia.

That means these runnableExamples were never tested. Why is this the case? I only discovered this in #20091.

7af484da94 Add client.close() in httpclient examples. (#20118)
Without this, the httpclient examples are essentially setting you up for failure. I was bitten by this when my app became unable to open any more sockets.

I'm not entirely sure how long this will relevant, as I hope destructors will be added to an upcoming version of the stdlib. But figured it was worth submitting anyways!
