This was something I wanted to do for some time now. First thing I didn’t like about the existing AST Browser implementation in groovy was that the compilation bits were all intermixed with the Swing tree view implementation bits. Secondly I wanted this tool to be available on web, complementing the Groovy Web Console.
So, here is the web-based version of AST Browser – deployed on Google App Engine environment – http://groovyastbrowser.appspot.com/
Accompanying this work, here is an article published on DZone: http://groovy.dzone.com/articles/groovy-ast-browser-web-now
