[otj-users] parser for OT/J

Of course! We wouldn't be able compile OT/J without a parser ;-)

The grammar that is in production is
	https://svn.objectteams.org/trac/ot/browser/trunk/src/plugins/org.eclipse.jdt.core/grammar/otj_jp.g
But be warned that this grammar is not an easy read, because it is written under the tight 
constraints of an LALR(1) parser generator, and additionally contains stuff for error recovery etc.
Also note, that this grammar contains rules for an experimental join point query language that
is not currently supported.

So, I'd actually recommend to directly use the Eclipse Java AST, if that is in any way feasible
for what you're planning to do. This AST has been extended to contain nodes for all OT/J elements.
Plus you'd get the benefit of a plethora of utilities built around this AST.
Should you need some pointers for working with this AST, please feel free to ask.

I might note, that we did have a JavaCC parser, but I currently couldn't tell about the
state of this piece of work.

cheers,
Stephan
