• Before inclusion
  • And/or evaluate too much
  • Standard library functions: math.modf, math.fmod
  • Variable arguments and multiple returns
  • Use prompt and abort instead of throw and catch
  • Standard library function: module
  • Standard library function: table.sort
  • Get the official Lua 5.1 test suite running
• Eh
  • Standard library function: math.frexp
  • Better testing of standard library modules io, os
  • Function environments (getfenv and setfenv)
• Differences
  • Guile Lua will accept the "break" statement anywhere
  • math.sqrt accepts negative arguments since Guile's numeric tower is capable of representing complex numbers

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

Before inclusion

TODO Variable arguments and multiple returns

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

Eh

TODO Standard library function: math.frexp

Pending some additions to Guile's numeric tower.

TODO Better testing of standard library modules io, os

TODO Function environments (getfenv and setfenv)

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
