I am at OpenExpo and while chatting about KDE 4.1 with the nice people at the KDE booth, I realised that some of the Debtags Technology™ could be used to make a really good application launcher.
After a bit of prototyping, I present you the Application Launcher Startup Kit:
git clone http://people.debian.org/~enrico/2008-09/launcher
There are two python scripts in it: index that indexes your existing
.desktop files in a Xapian database, and query that contains a function to
query the index, and when run with the query keywords as parameters, it shows
the results. You give it a list of terms (and possibly of currently selected
categories), and it gives you:
- Spell checking suggestions
- Tag cloud generation
- Completion support
- Search results
It's more than fast enough to do all of this in real time, as the user types.
For example, on my system:
$ ./query imag
Found: 55 /usr/share/applications/gqview.desktop
Found: 51 /usr/share/applications/gimp.desktop
Found: 48 /usr/share/applications/gpicview.desktop

Now, it's just a matter of putting a GUI on top of it. I am not going to do it: that is up to you.
