Hello,
during some scripting for a font database to be used with LuaLaTeX, I
encountered two difficulties (Unix-only) :
- I couldn't know if I had the permission or not to write on a file:
lua.attributes() gives me uid, gid and the persmission string, but this
is unusable as I don't know what is the uid of the program, and I know
even less if I'm in a group that fits the permissions...
- I couldn't know where the symlinks were pointing to
A solution to these two problems would be the inclusion of the posix[1]
library. I know you're quite reluctant to new libraries inclusion, but I
think these two problems (especially the first one) will be encountered
by many users or at least package writers under Plain/LaTeX. Would you
be interested in a patch implementing the needed functions to solve
these problems? Or including the whole library? It's in the public
domain so there aren't no legal problems.
Thank you in advance,
