Previously when using Campfire, we used a library called Marshmallow, that joins a room and says what commit happened in an SVN repository. Since moving over to a Git repository, we needed a new bot that would come and tell us what was happening.
I turned to an unofficial Campfire API called Tinder, and wrote a little bit of code to join a single room that has guest access turned on, to say what was just committed to the repository.
The code joins a room, looks for commits in Git, and "speaks". It runs post-update, so put this in the /git/repo.git/hooks/post-update file. Don't forget to chmod 770 the post-update file so it can be executed. This hook is basically what is run when you do a push to the repository.
#!/usr/bin/env rubyrequire 'rubygems'
require 'tinder' #require the tinder gem# room: the subdomain you use for subdomain.campfirenow.com
# path: path to your repository you want to track
# hash: the guest hash, should be about 5 characters long. you need to turn on guest access in campfire manually first.
# msg: a nice commit message, check the manual for git-log for some flags
# %an is the author name, %ar is time since the commit, %s is the message, %H is the commit hash
config = {
:room => 'SUBDOMAIN',
:path => '/git/repo/path/repo.git',
:hash => 'GUEST_HASH',
:msg => 'Commit by %an (%ar): \"%s\"%nChangeset: http://trac.yoursite.com/changeset/%H'
}# create new campfire instance with the room
campfire = Tinder::Campfire.new(config[:room])
# get the guest room
room = campfire.find_room_by_guest_hash(config[:hash], 'gitbot')# get all the commits
commits = `cd #{config[:path]} && git log -#{ARGV.size} --pretty=format:"#{config[:msg]}"`# say something for each commit
commits.each_line do |commit|
room.speak "#{commit}"
end
I added some comments above explaining what was going on. You might also be curious about the msg hash. The changeset link is going to a modified version of Trac, which I've installed a Git Plugin, so Trac uses our Git repository instead of our SVN repository. There's probably better tracking systems out there, but we're just reusing what we had before.
