I recently started to work on a new Django project and tried use my default IDE: Komodo IDE. Unfortunately it didn’t work out the way i wanted. Code cpmpletion didn’t work just as the import of my app. Here’s how i solved it:

Add a new Python import directory: Preferences -> Languages -> Python

My Django resides in /Library/Python/2.5/site-packages. Your installation may be in a different location.
Create a Komodo project for your new Django project and edit it’s properties: Properties -> Languages -> Python My project resides in /Users/dkerwin/development/django/stag_party with several application inside.

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

Useful BASH setting: Ignore duplicate commands

There are many settings that make BASH even more usable. As many people doesn’t seem to know this particular parameter i post it here:

HISTCONTROL="ignoredups"

This setting in bashrc or profile makes BASH ignore duplicate commands when searching the history. It’s pretty useful if you had entered the same command several times.
