On, most projects list the programming language(s) their software uses:

It would be useful if there was a way to get a list of all the projects that use "X" programming language, in my case Vala. Does Launchpad provide this functionality? Are there any 3rd party tools that can do this?

Good question. I'm curious to know if there is an answer to this. – Nathan Osman Dec 7 '10 at 6:17

As Marco Ceppi has pointed me towards launchpadlib, I wrote a little script that will do this for you. alt text download it here

Run the script by calling python in a Terminal after you've downloaded and saved it. It will ask you for a programming language, case insensitive, and a search query (where wildcards, *, are allowed). If you leave either of them blank, it will search across all, rather than none.

You'll need to install  python-launchpadlib before you can use it.

Here's some example output:

stefano@3000-G530:~$ python 
Enter a programming language or leave blank to find projects in all languages:
>>> Python

Not the best code I ever wrote though... But it works fine. – Stefano Palazzo Dec 7 '10 at 16:38
Slightly off topic, but: Thanks for making me aware of this library :P – Ward Muylaert Dec 7 '10 at 16:49
Would it be possible to paste the python script directly into the answer. The paste is no longer available. Side note: see this question for this issue: Does pastes made on Ubuntu Pastebin Service get deleted? – Aditya Oct 22 '13 at 17:39

Launchpad doesn't have this functionality. The request for it is bug #2630, which you may want to subscribe to.
