Fajin Yuan mentioned it in his talk last week at the SSTD Software Engineering meeting. This and also Mylar, a tool for integrating Bugzilla/Trac into Eclipse.
Installation
Instructions are at the Tigris site. This is fine if your Eclipse proxy settings work but I couldn't get this going even when I made the settings in the Install/Update preferences. There is a zip file you can use instead. I downloaded and pointed the Eclipse settings to pick this up as a local site. All went well from there.Initial Impressions
The plugin works as another view in Eclipse. The SVN Repository window was initially blank. I set up the SVN style URL for the NDG repository and it displayed everything in a tree view. I also had to provide username/password. I hope the latter isn't stored(!).It looks good and seems to implement everything that I would typically need to do on the command line in a graphical form ... check ins and check outs display diffs, check in records, different file revisions in the editor etc ... but I think I will need to re-check out my local copy so that it is in sync with this.
