High priority (version 0.8.12)
==============================
* implement message passing built-ins
* add --deadlock_prevention:on|off switch? timeout for locks?
* real types for template results
* built-in serialization
version 0.9.0
=============
- test the sort implementation again
- warning for implicit openArray -> varargs convention
- implement explicit varargs
- tests: run modules that contain "#RUN_ME", compile the other
modules; run the GC tests
- fix the streams implementation so that it uses methods
- fix overloading resolution
- wrong co-/contravariance
- make ^ available as operator
- implement closures for the C code generator
Bugs
----
- proc (x: int) is passable to proc (x: var int) !?
- the parser allows empty object case branches
- pegs: the anchor '^' does not work because many procs use a linear search
and matchLen()
- bug: generic assign still buggy
- Optimization: If we use a temporary for the result anyway the code gen
should make use of this fact to generate better code...
- bug: invoking a generic iterator twice triggers a code gen bug
- bug: forward proc for generic seems broken
- sorting with leads to a strange memory corruption!
--> system.swap or genericAssign is broken! And indeed, if reference counts
are not modified and the GC is triggered in between a swap, bad things
may happen!
version 0.9.XX
==============
- distinct types for array/seq indexes
- GC: marker procs for native Nimrod GC and Boehm GC
- implicit ref/ptr->var conversion; the compiler may store an object
implicitly on the heap for write barrier efficiency
- resizing of strings/sequences could take into account the memory that
is allocated
- typeAllowed() for parameters...
- find a way to reintroduce the cleanup() pass for C code generation: this
is hard because of partial evaluation --> symbol files will fix this as
a side effect
- EcmaScript needs a new and better code gen: simply adapt the C code gen to it
- prefer proc in current module over other procs with same overloading result?
- generalized case statement (requires better transf)
- tlastmod returns wrong results on BSD (Linux, MacOS X: works)
- nested tuple unpacking
- better error messages for used keywords as identifiers
- case statement branches should support constant sets
- 'nimrod def': does not always work
- test branch coverage
- checked exceptions
- fix implicit generic routines
Library
-------
- radix tree for strings; maybe suffix tree
- locale support
- conversion between character sets
- bignums
- ftp (and other internet protocols)
- pdcurses bindings
- queues additional to streams: have two positions (read/write) instead of one
- for system:
proc `@` [T](a: openArray[T]): seq[T] =
newSeq(result, a.len)
for i in 0..a.len-1: result[i] = a[i]
--> ensure @[] calls the array version!
Version 2
=========
- language change: inheritance should only work with reference types, so that
the ``type`` field is not needed for objects! --> zero overhead aggregation
BETTER: ``is`` and safe object conversions only work with ref objects. Same
for multi methods.
- explicit nil types?
* nil seq[int]
* nil string
* nil ref int
* nil ptr THallo
* nil proc
- better for backwards compatibility: default nilable, but ``not nil``
notation:
type
PWindow = ref TWindow not nil
The problem with ``nil`` is that the language currently relies on it for
implicit initialization. Initialization is different from assignment. The
issues can "easily" dealt with by ensuring:
var x = myProc() # checks myProc() initializes every pointer explicitely
- the two other parsers
- rethink the syntax: distinction between expr and stmt is unfortunate;
indentation handling is quite complex too
Low priority
------------
- ``when T is int`` for generic code
- ``when validCode( proc () )`` for generic code
- macros: ``typecheck`` pragma; this allows transformations based on types!
- find a way for easy constructors and destructors; (destructors are much more
important than constructors)
- code generated for type information is wasteful
