PkgHist -- get the list of installed packages from pacman.log

an old script i wrote last October:o, cleaned it up in hopes of getting it tested for ARMTools
the script in the wiki doesn't actually work as it tracks all packages you ever installed
and some of us have packages that are installed up not in pacman.log

#!/usr/bin/env python

    print 'Usage:'
    print '       -l | --list -- list all packages installed, based on pacman.log'
    print '\n Note: some packages may be missing in the list,'
    print '  so if you installed group [base] at install,'
    print '  then you should pass that to pacman as well if you re-install.'
    sys.exit(0)

LOGFILE = '/var/log/pacman.log'

fp = open(LOGFILE)
try:
    log = fp.read()
finally:
    fp.close()

history = {
    'installed': {},
    'removed': {},
    'upgraded': {}
}

for match in re.findall('\] (installed|removed|upgraded) (.+?) \(', log):
    history[match[0]][match[1]] = history[match[0]].get(match[1], 0) + 1

installed = history['installed']
removed = history['removed']
upgraded = history['upgraded']

# -- some packages, (at least) in older Arch installs don't get registered in pacman.log
# -- so track them from when they get upgraded
for pkg in upgraded:
    if not installed.get(pkg):
        installed[pkg] = upgraded[pkg]

for pkg in installed:
    if removed.get(pkg, 0) < installed[pkg]:
        print pkg

please attach your pacman.log if you test it and it misses anything

you can check if it works by

pkghist --list | sort > /tmp/-out-ph
pacman -Qq > /tmp/-out-pm

then

diff /tmp/-out-p{h,m}

or

comm -3 /tmp/-out-p{h,m}
