Last week in Launchpad’s web API

Barry Warsaw, Francis Lacoste, and I gave an IRC chat about the Launchpad web service as part of Ubuntu Developer Week. There’s a transcript available in case you missed it.

The big news from last week is that we finally have the API documentation being generated whenever a new version of Launchpad is deployed. Whatever server your script is running against, the /+apidoc URL will contain the reference documentation for that version of Launchpad.’s documentation will change when we do an official release of Launchpad, and’s and’s will be updated much more often, as our changes get pushed out to those servers.

But there’s more! I also added support to launchpadlib for access to the binary files hosted by Launchpad: mugshots, bug attachments, and so on. This is everything described in the reference doc as “a file resource.” If you upgrade launchpadlib, you can now access these files with a Pythonic file object interface.

The server side of this has been in place since we launched the web service, so in theory you could have been messing with uploaded files this whole time by writing a custom-built client. But only recently did I update the hacking document that makes it easy to see how to do this.

Finally, Edwin, Brad, and I have continued working on exporting the Launchpad registry. Of note are three new hosted-file resources: a project’s brand, logo, and icon. Project groups also have more of their fields published.

This week: more things published through the registry, hopefully some progress on bugs as well.
