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...
Why not just do io.open(,"w") ? if it fails, you couldn't write. And
such a test will do the 'right thing' if the disk is full or mounted
read-only.
- I couldn't know where the symlinks were pointing to
lfs has lfs.symlinkattributes() for this, but I have never
used it so I am not sure how useful that is.
A solution to these two problems would be the inclusion of the posix[1]
library.
Libraries that do not run on win32 are definitely out of the question.
Best wishes,
Taco
