KolorTool For KDE 4

Maybe I’m blind, but I can’t find a nice, simple color tool on KDE 4 for my life. The color picker Plasmoid is okay, but it doesn’t do what I want: to mangle colors and get the resulting hex values.

To fix this, I threw together this little Python bit and installed it as KolorTool. Does what I need, just throws up a color dialog for me to play with.

KolorTool

#!/usr/bin/python
# -*- coding: utf-8 -*-
import sys
from PyQt4 import QtGui
from PyKDE4 import kdeui

app = QtGui.QApplication(sys.argv)
picker = kdeui.KColorDialog();
picker.show();

sys.exit(app.exec_());

Enjoy, modify and let me know if there is an existing, standard tool like this please!

Move Subversion repository without svnadmin

$ rsync -av blowpass.svn.sourceforge.net::svn/blowpass/* blowpass
$ svnadmin dump blowpass/ > blowpass.dump
$ svnadmin create clearpass
$ svnadmin load clearpass < blowpass.dump

I have been having a terrible time trying to figure out how I can get the Subversion repository for ClearPass out of SourceForge. I could not find a single reference to svnadmin on the SourceForge and no examples of exporting without it. So I took matters into my own hands. Below is a quick and dirty shell script that exports and imports a repository one revision at a time, using common Linux command line tools and the svn command. I'm going to do more testing before using it for real, but so far it has done well. Hope this helps someone else in my position.

Download it: svncrossload

SVN to Twitter

I’ve been really getting into developing my KickTweet project and set up a Twitter account for it at http://twitter.com/KickTweet. I wanted to feed in my subversion commits so I did some searching.

What I found was twitvn a monstrous (50-ish ‘real lines) Python script that sends commits to Twitter. I find that ridiculous. So here is my version, it drops right into the post-commit script and could be reduced to 2-3 active lines.

#!/bin/bash
REPOS="$1"
REV="$2"

TWEET="SVN Log (r$REV): $(svnlook log $REPOS -r $REV)"
curl -u KickTweet:mySecretPassword -d status="${TWEET:0:139}" http://twitter.com/statuses/update.xml

Note that the use of the ‘${TWEET:0:139}’ is a definite bashism, and not portable.

#!/bin/bash
REPOS="$1"
REV="$2"

TWEET="SVN Log (r$REV): $(svnlook log $REPOS -r $REV)"

if [ "${#TWEET}" -gt 140 ]; then
  TWEET="${TWEET:0:137}..."
fi

curl -u KickTweet:mySecretPassword -d status="${TWEET:0:139}" http://twitter.com/statuses/update.xml
