Re: Low level Linux lib, was: C Based Hash Libs

[Phil Leblanc <philanc@...>]

Hi Paul,

Thanks for your suggestions regarding my "Low-Level Linux Library for
Lua" ("L5") [1]. The objective is really to include only low-level
stuff that cannot be written in Lua.

I agree that support for signals is one big missing item. Will look into it.

As you have noted, functions such as getpwnam, getpwuid, glob are
candidates for a Lua implementation. As such, they could also be nice
additions to the Lua part of L5 (see the l5 subdirectory).

I actually have an even lower-level project, VL5 [2] which wraps the
Linux system call interface. This is more a toy - obviously a
dangerous one! - very ABI-dependant :-)  I may also merge the syscall
interface into L5 some day.

Any additional comment, request, bug report are most welcome!! Feel
free to open an issue on the related github repositories
