What do you mean "other programs"? As in, an elegant parsing system? Or how other apps parse pacman.conf?
How other C-coded apps parse their config files in general. I don't do it often in C, so I have no idea how it is usually done.
Depends on the complexity of the app, but most of the time it's done manually in a similar way that we do it... that is, getline, strcmp, strcmp, strcmp, loop, done.
I actually don't think our parsing is all that bad, it could just use some more info on the error case.
Sorry, for my previous post in old thread.

I'm suggesting to use 3rd party library for parsing. I see 2 choices: 1) iniparser there is nice console app that can be used by shell scripts to parse config (made by James): http://archlinux.org/~james/projects/network/iniread-0.1/ usage example: http://archlinux.org/pipermail/arch-dev-public/2007-April/000415.html 2) libconfuse this one has nice validation features -- Roman Kyrylych (Роман Кирилич)
