On Launchpad.net, 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?

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 name_of_the_script.py 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 test.py 
Enter a programming language or leave blank to find projects in all languages:
>>> Python
Enter a search query or leave blank for all:

  • 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?

  • I'll second that. I'd really like to see a way of searching launchpadlib using wildcards and the pastebin no longer exists... Mar 20, 2019 at 15:42

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


You can find particular project in the following link.But as far as i know you can not list projects that uses X programming langauge.
