Sharing my script to show version difference of installed packages

syockit · 2013-12-04 16:59:51

Hi all.

Sometimes I don't want to just pacman -Syu. There are many packages that are big but introduce only minor bugfixes (usually libreoffice packages* are the culprits), so I don't want to have to install those.

This is something I cooked up a while ago to show version difference of currently installed packages with the latest packages in repository.

It's in python3, and uses python-termcolor.

It outputs something like this:

acl                  :     2.2.52-1            -->     2.2.52-2           
archlinux-keyring    :        20130926-1       -->        20131027-1      
bison                :         3.0-1           -->         3.0.1-1        
cracklib             :      2.9.0-1            -->      2.9.0-2

Here is the script:

#!/usr/bin/python3
from subprocess import check_output
from termcolor import colored
pacman_out=check_output(["pacman","-Sl"], universal_newlines=True).split("\n")
outlist = []
len_pkgname = 0
len_majver = 0
len_newver = 0
len_oldver = 0
for pkgs in pacman_out:
    if not "[installed" in pkgs:
        continue
    if "[installed]" in pkgs:
        continue
    pkg_split = pkgs.split(" ")
    newver = pkg_split[2]
    oldver = pkg_split[4].rstrip("]")
    for i in range(min(len(newver),len(oldver))):
        if newver[i] != oldver[i]:
            break

    pkgname = pkg_split[1]
    majver = newver[:i]
    oldver = oldver[i:]
    newver = newver[i:]
    outlist.append((pkgname, majver, newver, oldver))
    len_pkgname = max(len_pkgname, len(pkgname))
    len_majver  = max(len_majver,  len(majver))
    len_newver  = max(len_newver,  len(newver))
    len_oldver  = max(len_oldver,  len(oldver))
for (pkgname, majver, newver, oldver) in outlist:
    print("{}: {}{} --> {}{}".format(
        pkgname.ljust(len_pkgname),
                colored(majver.rjust(len_majver),"cyan"),
                colored(oldver.ljust(len_oldver),"cyan",attrs=["bold"]),
                colored(majver.rjust(len_majver),"magenta"),
                colored(newver.ljust(len_newver),"magenta",attrs=["bold"])))

I hope pkgbrowser will include something like this in the future.

P/S: * these packages will break anyway in the event the dependencies has had some ABI changes.

EDIT: swapped new and old version columns. Thanks, karol!

Cool. Moving to Programming and Scripting...

syockit · 2013-12-04 17:22:49

Ah, sorry then. Because the subtitle for pacman's subforum has "Also the place for discussion about pacman in general.", I thought this would be appropriate there.

jasonwryan · 2013-12-04 17:24:59

It's nothing to apologize for: it is just more likely to attract the interest of people who are more oriented towards actually programming for Arch here.

karol · 2013-12-04 17:45:03

I think the columns with version numbers should be switched around. I update from 0.1 to 0.2 i.e. 0.1 -> 0.2.

Arch doesn't support partial upgrades ;P

I just found out there's a grand thread that has tons of self-baked scripts Maybe I need to lurk bbs more often.

Why not suggest adding this feature?
Currently it shows only the version that is going to be installed https://bbs.archlinux.org/viewtopic.php … 3#p1316573

I've mated pacman's checkupdates with my old script https://bbs.archlinux.org/viewtopic.php … 80#p829780

No colors though.
