GsoC update: Week 12

With GSoC 2011 completion I’d like to let you know where I’m with the project progress since last week. In summary, the project is half-finished at this time, as I was overcome with complication of the tasks and limited time. But there’re a few achievements as well.

Project successes:

• Project is building and generating grammars for both Groovy and Java
• Groovy grammar is now defining all tokens explicitly as ANTLR3 is not generating LITERAL_name
• I've removed all not working rules from Groovy file so it's at least building and allowing you to run compiler
• Fixed almost all problems in Java code, most problems were connected to missing interface GroovyTokenTypes as this isn’t generated by ANTLR anymore so I've used instead GroovyLexer
• I've created base class for parser so ANTLR grammar file is a now a bit cleaner
• I've incorporated changes connected to ANTLR runtime changes so now we have GroovyTreeAdaptor and associated classes
• I've tried to move code associated to custom node creation but it is still work in progress (I want to start with compilationUnit, annotations and package definition)
• I've updated Java 2 Groovy converter, but I couldn’t find all necessary rules in Java grammar
• ASTFrame is working, but as compilation unit is not available yet it's not displaying tree

Project challenges:

• Remove reference to antlr3 jar from bootstraper (couldn't run the one downloaded from maven)
• The grammar is still not working even with simple scripts and this is major challenge after that it should be easier to port the rest of rules

Cheers
