Hi,

This is one part of the makepkg test suite I am working on. It is fairly a simple class that takes a pacman package filename and does some parsing. Currently that involves getting the file list and the info from the .PKGINFO file.

I am still fairly new to python so I am looking for comments on how this could be improved. One idea I have had is to not initialize all the fields in the pkginfo dict and add a test if an array exists before appending. It would make the code tidier but that would mean the need to test if the field exists when comparing it later.

I didn't really look at the script, but I made a similar parser [1] earlier, initially for AUR2 purposes. Looking over it, it seems I don't include the file list during parsing, but that can probably be easily added in. Perhaps it can be expanded upon, instead of creating a new one. If not it should at least help.

So this is both a pkgbuild and pkginfo parser ?

Correct. Two classes for the two formats.

For the AUR, you just need pkgbuild parser, right ? And this is much more complex than pkginfo parser. Actually that's why I hate pkgbuild :)

Since community is no longer in the AUR, yes. At the time though, I was also targeting tarball packages since I wanted to parse the packages in community. Unfortunately tarball packages are much easier to parse than PKGBUILDs :(.

There was another pkgbuild parser in python , written by stonecrest, and used there : http://projects.archlinux.org/?p=dbscripts.git;a=blob;f=cron-jobs/check_arch...

Thanks, might be useful. I'll look into it when I have more time.
