Hudson console markups

(I started cross-posting blogs to my own website.) Despite all the report comprehension in Hudson, such as JUnit, PMD, FindBugs, etc., log files still hold a special place in terms of capturing what has really happened. Hudson does a bit of AJAX in this space to let you follow output as it comes, but the log is basically just a plain text that doesn't really have structures. But that is changing. One of the recent improvements in Hudson is the infrastructure and extension points for Hudson (and its plugins) to mark up the console output to improve interactivity and do some cool stuff. I prepared two kinds of extension points for this. One is the ability to scan the console output line by line and add arbitrary markup to it. This can be used for context-independent markup, for example to turn URLs into hyperlinks, look for keywords like "ERROR", that sort of things. The other kind is more interesting, where we can place anchors (I call them 'notes') at arbitrary points during the output, and those notes can then in turn generate markups. This enables highly context sensitive markups, which I think has a lot of potential. For example, I started putting a note for every Ant target that gets executed during the Ant execution. I can use this to generate outline for the console output, so that you can jump to the interesting targets, or move up/down to next target very quickly. For simple build scripts, I can let users cli...
