RE Language-agnostic actions - if you treat this as a strategy pattern
(like I seem to recall you did in the antlr 2 code base) this could
work really well. What would be really cool IMNSHO:
grammar Foo;
foo : xxxxxx {...@dox(...); } ;
fee : xxxxxx {...@doy(...); } ;
and the generators could generate a spec/interface/abstract class for
the action methods, like in Java:
public interface FooActionStrategy {
void doX(...);
void doY(...);
}
and generate
setActionStrategy(FooActionStrategy x) {...}
that would be used in the code. All that's needed is an implementation.
If all of the action code were simple action-strategy calls, this
should be generatable in pretty much any target language. (Of course I
haven't given this much thought, but it feels pretty good OTTOMH)
