This is an org-mode todo list of stuff that needs to be done for Guile Lua.

* Before inclusion
|
|
** DONE And/or evaluate too much
|
|
CLOSED: [2011-04-19 Tue 19:36]
|
|
** DONE Standard library functions: math.modf, math.fmod
|
|
CLOSED: [2011-04-21 Thu 15:43]
|
|
** TODO Assignment cannot be naive left-to-right
|
|
a,b = b,a should work correctly
|
|
** STARTED Multiple values
|
|
What's the deal? In Lua, the rightmost expression in a
|
|
comma-delimited list (such as in a function application, or the
|
|
right-hand side of an assignment) may result in multiple values.
|
|
|
|
** TODO Variable arguments
|
|
|
|
** TODO Function environments (getfenv and setfenv)
|
|
** TODO Use prompt and abort instead of throw and catch
|
|
** TODO Standard library function: module
|
|
** TODO Standard library function: table.sort
|
|
** TODO Get the official Lua 5.1 test suite running
|
|
** TODO Lua working at the REPL
|
|
** TODO Document some stuff
|
|
|
|
* Eh
|
|
** TODO Standard library function: math.frexp
|
|
Pending some additions to Guile's numeric tower.
|
|
** TODO Use module binders
|
|
** TODO Better testing of standard library modules io, os
|
|
** TODO compile-tree-il.scm should be rewritten
|
|
Right now it's a jungle of tree-il constructors. There's a lot of
|
|
boilerplate code that could be made much nicer using macros and
|
|
parse-tree-il.
|
|
|
|
* Differences
|
|
Here are some difference in Guile Lua's behavior that should not cause
|
|
problems in porting Lua code.
|
|
|
|
** Guile Lua will accept the "break" statement anywhere
|
|
For instance:
|
|
for k,v in table do
|
|
function breaky() break end
|
|
end
|
|
Would be rejected by Lua but not by Guile Lua.
|
|
|
|
** math.sqrt accepts negative arguments since Guile's numeric tower is capable of representing complex numbers
|
