Points to you if some of this seems familiar from GPSD…
Keep mechanism and policy separate
Mechanism goes in irkerd. Policy goes in irkerhook.py
irkerd is intended to be super-simple and completely indifferent to what content passes through it. It doesn’t know, in any sense, that the use-case it was designed for is broadcasting notifications from version control systems. irkerhook.py is the part that knows about how to mine data from repositories and sets the format of notifications.
If you think the mechanism needs an option, think again
Because irkerhook.py does policy, it takes policy options. Because irkerd is pure mechanism. it shouldn’t need any. If you think it does, you have almost certainly got a bug in your thinking. Fix that before you modify code.
Never configure what you can autoconfigure
Human attention is more expensive than machine time. Humans are careless and failure-prone. Therefore, whenever you make a user tell your code something the code can deduce for itself, you are introducing unnecessary inefficiency and unnecessary failure modes.
This, in particular, is why irkerhook.py doesn’t have a repository type switch. It can deduce the repo type by looking, so it should.
Check for merge requests at https://gitorious.org/irker
Do make pylint to audit the code.
Run irk with a sample message; look at #irker on freenode to verify.
Bump the version numbers in irkerd and irkerhook.py
