Revision: 1545 Author: mirkostocker Date: 2006-07-27 11:29:13 -0700 (Thu, 27 Jul 2006) ViewCVS: http://svn.sourceforge.net/rubyeclipse/?rev=1545&view=rev Log Message: ----------- Added a first version of the AST viewer plugin, I had some problems with automatically updating the view, so this currently needs to be done by hand (with the refresh icon). I also plan to make it configureable, so you could select the nodes you don't want to see (for example NewlineNode). Feel free to contact me if you have any suggestions for further functionality!
