README

We set up our campfire so each project has a specific room. We set up our 
redmine projects so they're tied to our svn repository. This allows us to grab
changesets and to close issues from commit messages. It also gives us pretty 
diffs.

What notify-campfire-multi.rb does is allow us to post a notice that a commit 
has happened (and by who) and then gives us a link to our redmine diff or it 
can just paste the diff into campfire (which was cool but takes up quite a bit
of space if you have a lot of commits).

To use, put it in your hooks directory (ours is /var/svn/agora/hooks). Set up 
your post commit hook and then put this on the last line:

/var/svn/agora/hooks/notify-campfire-multi.rb $1 $2

You need to make sure post-commit and notify-campfire-multi.rb are both 
chmod +x and have permissions to run in the hooks directory

The way this works is for each room you have a block like:

bacalhau_room   = campfire.rooms.detect { |r| '288431' == r.id }
if dirs_changed =~ /bacalhau/
  last_changed_author = `svnlook info -r#{revision} #{repository_path}`.split("\n").first
  diff = `svnlook diff -r#{revision} #{repository_path}`
  log_message = `svnlook propget #{repository_path} svn:log -r#{revision} --revprop`
  log_message = wrap_text("#{last_changed_author} committed revision #{revision} with log message: #{log_message}")
  bacalhau_room.paste("#{'-' * 80}\n#{log_message}\n#{'-' * 80}\n" + diff)
end

The first line there finds the room we're going to speak to. Next it determines
if this commit is happening against a directory within the correct project. The
rest of it is just figuring out who made the change, what did they change and 
what was their log message. The last line pastes both the commit message and 
the diff to the campfire room.

Alternatively you can use this form:

gh_regular_expression = /guitarhero/
if dirs_changed =~ gh_regular_expression
  last_changed_author = `svnlook info -r#{revision} #{repository_path}`.split("\n").first
  log_message = `svnlook propget  svn:log -r#{revision} --revprop`
  log_message = wrap_text("#{last_changed_author} committed revision #{revision} with log message: #{log_message}")
  guitarhero_room.paste(log_message)
  # post the link to our redmine
  guitarhero_room.speak("http://agora.redmine.made.up.crap.com/repositories/diff/guitarhero?rev=#{revision}")
end

Which does almost exactly the same thing but it speaks a link to the diff 
instead of pasting the entire diff into the room.

This requires tinder to work:
sudo gem install tinder
