I used to tail my log files in the console/terminal with “$ tail -f somelog.log”. But this is not really working if you have Eclipse in fullscreen mode (in Mac OS X). I recently stumbled across a very nice plugin, which basically let’s you do the same thing in a “Window-View” just like the Console- or Outline view of Eclipse. The plugin supports also multiple log files, so you can easily switch between a debug an normal log file. Furthermore you can define some rules (word or regex-match) which then can, if they match, change the particular line’s back- and foreground color… exceptions can’t hide 🙂 To install this extension copy the following URL and go to Eclipse > Help > Install new Software and install the “Log Viewer Feature”. Restart eclipse and open the Log Viewer with Window > Show View > Other > Log Viewer. You then need to add all the log files you want to tail and create your custom rules (see picture for more infos). Please also visit and star this project on it’s Google Code site.
