|
==============
|
|
|
|
- document special cased varargs[untyped] and varargs[typed]
|
|
- The remaining bugs of the lambda lifting pass that is responsible to enable
|
|
closures and closure iterators need to be fixed.
|
|
- ``concept`` needs to be refined, a nice name for the feature is not enough.
|
|
- Destructors need to be refined.
|
|
- make '--implicitStatic:on' the default; then we can also clean up the
|
|
'static[T]' mess in the compiler!
|
|
|
|
- add "all threads are blocked" detection to 'spawn'
|
|
- Deprecate ``immediate`` for templates and macros
|
|
|
|
|
|
version 1.0
|
|
===========
|
|
|
|
- map ``string`` and ``seq`` to ``std::string`` and ``std::vector``
|
|
- macro support for '='; bind '=' to a memory region
|
|
- remove echo $foo gotcha
|
|
- figure out why C++ bootstrapping is so much slower
|
|
- nimsuggest: auto-completion needs to work in 'class' macros
|
|
- The bitwise 'not' operator will be renamed to 'bnot' to
|
|
prevent 'not 4 == 5' from compiling. -> requires 'mixin' annotation for procs!
|
|
- split docgen into separate tool
|
|
- BUG: echo with template `$`*(info: TLineInfo): expr = toFileLineCol(info)
|
|
- make 'nil' work for 'add':
|
|
- resizeString
|
|
- incrSeq
|
|
- addChar
|
|
|
|
|
|
Concurrency
|
|
-----------
|
|
|
|
- test 'deepCopy' for closures
|
|
- implement 'foo[1..4] = spawn(f[4..7])'
|
|
|
|
Low priority:
|
|
- support for exception propagation? (hard to implement)
|
|
- the copying of the 'ref Promise' into the thead local storage only
|
|
happens to work due to the write barrier's implementation
|
|
|
|
|
|
Misc
|
|
----
|
|
|
|
- prevent 'alloc(TypeWithGCedMemory)'
|
|
|
|
|
|
Bugs
|
|
====
|
|
|
|
- Can lead to wrong C code:
|
|
|
|
template cd*(dir: string, body: stmt) =
|
|
## Sets the current dir to ``dir``, executes ``body`` and restores the
|
|
## previous working dir.
|
|
let lastDir = getCurrentDir()
|
|
setCurrentDir(dir)
|
|
try:
|
|
body
|
|
finally:
|
|
setCurrentDir(lastDir)
|
|
|
|
proc test =
|
|
cd dir:
|
|
var output = execProcess("git tag")
|
|
case meth
|
|
of DownloadMethod.git:
|
|
output = execProcess("git tag")
|
|
of DownloadMethod.hg:
|
|
output = execProcess("hg tags")
|
|
if output.len > 0:
|
|
case meth
|
|
of DownloadMethod.git:
|
|
result = @[]
|
|
for i in output.splitLines():
|
|
if i == "": continue
|
|
result.add(i)
|
|
of DownloadMethod.hg:
|
|
result = @[]
|
|
for i in output.splitLines():
|
|
if i == "": continue
|
|
var tag = ""
|
|
discard parseUntil(i, tag, ' ')
|
|
if tag != "tip":
|
|
result.add(tag)
|
|
else:
|
|
result = @[]
|
|
|
|
- VM: Pegs do not work at compile-time
|
|
- VM: ptr/ref T cannot work in general
|
|
- blocks can "export" an identifier but the CCG generates {} for them ...
|
|
- ConcreteTypes in a 'case' means we don't check for duplicated case branches
|
|
|
|
|
|
version 0.9.x
|
|
=============
|
|
|
|
- pragmas need 'bindSym' support
|
|
- allow simple read accesses to global variables --> difficult to ensure that
|
|
no data races happen
|
|
- pragmas need re-work: 'push' is dangerous, 'hasPragma' does not work
|
|
reliably with user-defined pragmas
|
|
- memory manager: add a measure of fragmentation
|
|
- implement 'bits' pragmas
|
|
- we need a magic thisModule symbol
|
|
- optimize 'genericReset'; 'newException' leads to code bloat
|
|
|
|
|
|
version 0.9.X
|
|
=============
|
|
|
|
- macros as type pragmas
|
|
- document NimMain and check whether it works for threading
|
|
|
|
GC
|
|
==
|
|
|
|
- hybrid GC
|
|
- use big blocks in the allocator
|
|
- provide tool/API to track leaks/object counts
|
|
- resizing of strings/sequences could take into account the memory that
|
|
is allocated
|
|
|
|
|
|
CGEN
|
|
====
|
|
- codegen should use "NIM_CAST" macro and respect aliasing rules for GCC
|
|
- ``restrict`` pragma + backend support
|
