People with access to devpad can just go to https://devpad.canonical.com/~gary to give it a whirl.
You can also add apidoc.launchpad.test to your /etc/hosts, start up a recent branch of Launchpad, and visit apidoc.launchpad.test. (Note that this will not be available on staging, edge, or prod.)
Things to try:
- Click on the book link on the top left. On the bottom left, look for the Launchpad section of the docs. It has a few ReST docs that I knew were actual documentation. It's easy to expose doctests like this, and I hope to eventually expose other docs, like the stuff from lazr.restful; if you want to add some docs here, let me know and I'll describe how to do it. It's pretty easy.
- Click on the Interfaces link on the top left. In the text box on the bottom left frame, type in ILaunchpadPermission. Click on the link. You'll see on the page an example of the information available--a hyperlinked description of the interface, the adapters registered for the interface, the registered utilities for that interface, the classes that implement the interface, and so on.
- Click on the zcml references link on the top left. Click on a zcml tag in the bottom left frame, like our own zope:securedutility. It will tell you what the attributes are for the tag, where it is defined and implemented, and what the subdirectives are.
- Click on the code browser link on the top left. Click on the "browse source code" in the link on the bottom left frame, or type in a name and click "Find". Start browsing around. You'll see everything is interlinked as you browse.
