New helper script: SVN updater using Growl notifications

daniel — Wed, 27 May 2009 10:16:27 +0000

This small helper script should be added to cron and checks your local working copies against the online repository. It can automatically update your working copies if a newer revision is available. The user will be informed using Growl popups. As Growl is only available for Mac users it’s a Mac only tool by now.

The script currently registers with Growl using the classes from Python bindings. This is not necessary and would also be done by growlnotify. I was just interested in how this whole Growl stuff works. Feel free to remove this parts.

When i started i was willing to do the whole Growl stuff manually which has worked very well from the command line but not from cron. Seems like the context or something else get’s lost and no notifications pop up anymore. To be able to run via cron i switched to growlnotify.

Installing iPython under MacOS X

If you don’t know iPython by now: check it out

It’s a pretty nice tool if you work with python from the terminal. Especially the easy way to get information about modules and functions. The easiest way to install (especially in a Mac environment) is to use the “alldeps” tarball.

deathstar-mac ~ $ wget http://ipython.scipy.org/dist/alldeps/ipython-alldeps-0.9.1.tar
deathstar-mac ~ $ tar xvf ipython-alldeps-0.9.1.tar
deathstar-mac ~ $ cd ipython-alldeps-0.9.1.tar
deathstar-mac ~ $ make

The default install location is ~/usr/local. You may change this by modifying the install scripts but for now use the default. Now it’s time to make some modifications to your profile. Add the following lines:

deathstar-mac ~ $ export PATH="$PATH:/Users/YOUR_USERNAME/usr/local/bin"
deathstar-mac ~ $ export PYTHONPATH=$PYTHONPATH:/Users/YOUR_USERNAME/usr/local/lib/python2.5/site-packages

Let’s complete the installation process:

deathstar-mac ~ $ iptest
deathstar-mac ~ $ cd ipython-alldeps-0.9.1/ipython-0.9.1
deathstar-mac ~ $ python setup.py install --prefix=~/usr/local
 
deathstar-mac ~ $ ipython
