A small wrapper script for setting the lib32-gtk environment.

Question

Hi all,
i've created a small script [1], which sets the gtk2 environment for
lib32 applications.
Thanks to buttons and alexwizard...
just put run_bin32_gtk before the app command.
I use this script for QT4 apps mostly, for instance:
run_bin32_gtk opera
or
run_bin32_gtk skype --disable-cleanlooks
so it fits best in my gnome environment...
best wishes

I did something similar a couple of months ago, but instead of attempting to be clever and guessing what the background image is supposed to be, I just write it in the filename. Since some pictures just end up being too bright (or whatever) when used as a background to a urxvt terminal, I added some extra parameters for setting gamma, brightness, tint and the direction the image should be rendered. It relies on hsetroot for actually rendering the picture.
#!/usr/bin/python
# set-background
import sys, os, string, re
patterns = [ (re.compile("t-([a-f\d]+)"), lambda x: "-tint \#" + x)
, (re.compile("b-([\d]+)"), lambda x: "-brightness -0." + x)
, (re.compile("g-([\d]+)"), lambda x: "-gamma "+ x)
, (re.compile("f-(v|h|d)"), lambda x: "-flip" + x)
def buildCommand(file):
output = ["hsetroot"]
output.append("-" + (string.split(file,".")[-2]))
output.append(file)
for token in string.split(file,".")[1:-2]:
for (pat,f) in patterns:
if pat.match(token):
output.append( f(pat.findall(token)[0]))
return string.join(output)
print buildCommand(img)
os.system(buildCommand(img))
# vim:set et:
So for instance, an image with the name background.t-704214.f-v.full.jpg would be rendered as a stretched image, flipped vertically with a sepia tint. The files are required to be in the following format NAME.(MODIFIER.)*TYPE.SUFFIX, where the the order and number of modifiers are unimportant. The gamma values are somewhat unintuitive, but I guess you'll just have to play around with it to get it right.
And to randomize the whole thing, I just used the following script in my .xinitrc to randomly pick a image from a folder.
#!/bin/bash
bg_folder="$HOME/.backgrounds";
pics=($(ls $bg_folder))
let "n = $RANDOM % ${#pics[@]}"
(cd $bg_folder; set-background ${pics[$n]})
