python and pacman.log

Cam · 2005-04-15 06:48:36

Okay, I'm mentally retarded when it comes to python. Nah not really, but I'm pretty new. I wanna parse the pacman.log for some info to use, sounds easy but it's not. I used to do a bit of PHP and I know I could do it super easy with that so this is driving me crazy that it doens't just work. I'm obviously doing something wrong somewhere I just can't figure out where.

I'm using code something like this, I want to get a list of what was installed and when.

import re

r = open('/var/log/pacman.log')
log = r.read()
r.close()
exp = re.compile('[(.+)] installed (.+)', re.MULTILINE)
prnt exp.match(log)

Every time it prints 'None" which isn't what I'm after. Basic debugging says log contains the data I'm chasing. Any tips would be greatly appreciated.

Thanks

what are you trying to do?
If you just want a python list (for gods sake, why can't they just call it an array), with each element being one of the strings found...

import re
r=open('/var/log/pacman.log','r')
log = r.read()
r.close()
rexp = re.findall('^.*installed.*$',log,re.M)
##rexp is now a list of install lines.
print rexp

ps. I am new to python too.

Thanks, works well enough that I can go from here I'll split the string up to get the name and date, that's easy enough. There'll be a thread in the user contributions forum soon with the result of this

me three

and cactus, they call it a list because a list can have multiple types in it, whereas an array implies a single type.

list sounds cooler too
