SVN to Twitter

September 19, 2008

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.

Update (2008-09-22)
Little tidbit to add into the script right before the curl call. If you want ellipses on commit messages over 140 characters, use this version.

#!/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
