No, there is currently no way to do this.

I doubt that I'll find the time to implement this feature in the near future, but could you nevertheless elaborate a little more about what options you would like to have and how the configuration should look like?

Something along the lines of Editable Email Notification would be handy:

http://wiki.jenkins-ci.org/display/JENKINS/Email-ext+plugin

Specifically, the token substitution mechanism would allow for wordy or concise messages to be configured for each job.

Note: since instant-messaging 1.10 (Jabber 1.12, IRCBot 2.7) you can extend the plugin with your own 'BuildToChatNotifier'

Do you have a guide for doing the self-extension of our own "BuildToChatNotifier" for this? Some of us aren't that adept at doing modifications on that level yet.

I've been staring at this for a few hours and think I have a general idea of what is involved, but a guide would help everyone.

For what it is worth, the messages are defined in: src/main/resources/hudson/plugins/im/build_notify/Messages.properties

SummaryOnlyBuildToChatNotifier.Summary=Project {0} build {1}: {2} in {3}: {4}
SummaryOnlyBuildToChatNotifier.BuildIsFixed=Yippee, build fixed!\n
SummaryOnlyBuildToChatNotifier.StartMessage=Starting build {0} for job {1}

I would love an option to at least disable the BuildIsFixed message. The two other messages should be changeable in the interface, probably globally and on a per job basis. The Summary message shows the job URL which already contains the job name and build number, not much point in repeating them.

Is there a way to disable the "Yippee, build fixed" message completely? It drives me crazy to see so much spam as the real info is in the next line.
