TO IMPLEMENT
|
||||
============
|
||||
|
||||
Plan
|
||||
----
|
||||
|
||||
* implement new memory manager --> hopefully faster turnaround times
|
||||
* implement LLVM backend --> faster turnaround times

Bugs
|
||||
----
|
||||
|
||||
- BUG: check if "break" is valid is not complete: "break" within "for"
|
||||
may be incorrect, if the called iterator is not in a loop
|
||||
--> check that "yield" is inside a loop!
|
||||
- BUG: returning an array does not work --> see md5.nim module
|
||||
- BUG: if not nodeOfDegree(g, 1) >= 0: inc(counter)
|
||||
- BUG: addr/deref may not work when interpreting
|
||||
- BUG: the parser allows empty object case branches
|
||||
- BUG: when optmizing cgen.c with Visual C++, GCC, LLVM (O3), it breaks.
|
||||
- BUG: ``-cc:bcc`` command line option does not error
|
||||
- BUG: symbol files still do not work
|
||||
- BUG: tlastmod returns wrong results on BSD (Linux, MacOS X: works)
|
||||
- BUG: sigmatch for ``len`` matches the open array too often... (?)
|
||||
|
||||
|
||||
High priority
|
||||
-------------
|
||||
|
||||
- typeAllowed() for parameters...
|
||||
- implicit conversions from ``ptr/ref T`` to ``var T`` and from
|
||||
``ptr/ref T`` to ``T``? Yes.
|
||||
- implement generic types
|
||||
- implement tuple unpacking
|
||||
- implement closures for the C code generator
|
||||
- implement a better memory manager
|
||||
- implement stack walking via assembler for horribly advanced optimizers
|
||||
|
||||
- documentation: ``[]`` overloading, type convertions,
|
||||
anonymous procs, ``len(s) == s.len``, type converters
|
||||
- documentation: type converters
|
||||
- implement two-phase lookup for generics (this is hard...): This is useful
|
||||
for macros too! Alternative: Explicit early name binding. Both are hard to
|
||||
implement
|
||||
- get rid of ``nkHiddenStdConv`` in several places: this mechanism caused more
|
||||
bugs than it ever solved!
|
||||
- language change: inheritance should only work with reference types, so that
|
||||
the ``type`` field is not needed for objects! --> zero overhead aggregation
|
||||
|
||||
For the next versions
|
||||
=====================
|
||||
|
||||
- multi-processor support
|
||||
- IDE
|
||||
- better support for GDB?
|
||||
- support for generation of dynamic libraries
|
||||
- better code generator: skip ropes datastructure, it uses too much memory
|
||||
- make set optimizations part of the transformation (--> all backends profit
|
||||
from it), but this really needs a more abstract code generator
|
||||
|
||||
|
||||
Further ideas/nice to have
|
||||
==========================
|
||||
|
||||
- queues additional to streams: have to positions (read/write) instead of one
|
||||
- introduce: refany type???
|
||||
- CLR code generator; better use XYZ? --> Version 1.2?
|
||||
- provide an interactive shell: if the user wants his commands
|
||||
to be executed, the command should end with #
|
||||
- implement packed arrays (bit arrays)/ packed records
|
||||
- implement tables (implement as library? - no! Builtin because of
|
||||
constructor syntax is nice to have)
|
||||
|
||||
|
||||
Version 2
|
||||
---------
|
||||
|
||||
- language support for aggregation:
|
||||
type
|
||||
TMyObject = object
|
||||
x: TOtherObject
|
||||
|
||||
--> can be done via type converters elegantly
|
||||
|
||||
|
||||
- type tags:
|
||||
type
|
||||
sqlString* = type string
|
||||
|
||||
everywhere where a string is expected, a "sqlString" is allowed, but not
|
||||
vice versa. However, this causes problems:
|
||||
|
||||
type
|
||||
TDollar = type decimal
|
||||
|
||||
TDollar * int --> allowed
|
||||
TDollar div int --> allowed
|
||||
TDollar + int --> not allowed
|
||||
TDollar + TEuro --> not allowed, or implicit conversion
|
||||
|
||||
--> Explicit converters are probably flawed
|
||||
|
||||
- explicit nil types?
|
||||
* nil seq[int]
|
||||
* nil string
|
||||
* nil ref int
|
||||
* nil ptr THallo
|
||||
* nil proc
|
||||
|
||||
.. code-block:: nimrod
|
||||
var
|
||||
x: string = nil # initialized with invalid value!
|
||||
if not isNil(x):
|
||||
# now x
|
||||
|
||||
- better for backwards compability: default nilable, but prefix ``!`` operator
|
||||
to specify that null is not allowed
|
||||
|
||||
type
|
||||
PWindow = ! ref TWindow
|
||||
|
||||
|
||||
|
||||
Library
|
||||
-------
|
||||
- xml, html, url, fastcgi: implement from scratch
|
||||
- socket library (does SDL for us?)
|
||||
|
||||
- gui module
|
||||
- finish json module: hard
|
||||
- socket, http, ftp, email, fastcgi: implement from scratch
|
||||
- ncurses bindings
|
||||
- osproc for Windows
|
||||
- bignums
|
||||
- python
|
||||
- TCL
|
||||
- automate module: expect-like module for Nimrod
|
||||
- parsecsv module
|
||||
|
||||
- YAML module
|
||||
|
||||
|
||||
Low priority
|
||||
------------
|
||||
|
||||
- ``when T is int`` for generic code
|
||||
- ``when validCode( proc () )`` for generic code
|
||||
|
||||
when compiles:
|
||||
|
||||
elif compiles:
|
||||
|
||||
|
||||
- copy more of C++'s object modell?
|
||||
- syntactic sugar for OOP:
|
||||
|
||||
type
|
||||
TObj* = object
|
||||
fx = 0.nat
|
||||
fy = 0.nat
|
||||
s = ""
|
||||
proc setX(var, val: int) = my.fx = val
|
||||
proc getX: int = return my.fx
|
||||
|
||||
`x=`: proc (var, val: int) = setX
|
||||
x: proc: int = getX
|
||||
|
||||
proc q*(query: int): int =
|
||||
# implicit "my: TObj" parameter
|
||||
# variables are looked up automatically:
|
||||
return fx
|
||||
|
||||
proc setEvent(var, e: TEvent): int =
|
||||
# implicit "my: var TObj" parameter
|
||||
nil
|
||||
|
||||
proc init(var) =
|
||||
# constructor
|
||||
nil
|
||||
|
||||
o.x = 13 # ambigious
|
||||
|
||||
- implement stack walking via assembler for horribly advanced optimizers
|
||||
- use `` notation for identifier concatenation?
|
||||
- Visual C++: emit ``default: __assume(0);`` for optimization
|
||||
- macros: ``typecheck`` pragma; this is really a good idea! This allows
|
||||
transformations based on types!
|
||||
- make callconv a set
|
||||
- partial generic instantation is missing
|
||||
- commas are not optional any longer as this may lead to bugs (which?)
|
||||
- get code generation for C++ exception handling right!
|
||||
- find a way for easy constructors and destructors; though constructors are
|
||||
flawed... destructors are not, however!
|
||||
- multiple dispatch
|
||||
- multiple dispatch: no, but provide a proc ``typeId`` to allow the user to
|
||||
implement it efficiently
|
||||
- replace ropes with strings in the C code generator: This may yield a HUGE
|
||||
speedup of the compiler! (10%)
|
||||
- code generated for type information is wasteful
