[antlr-interest] Rule automation

[Martin Potier]

Hi all,

I've got something on my mind that the Definitive ANTLR Reference
couldn't solve (yet, I'm not tottally through it).
Is there a way with ANTLR v3 to automate some rule ?

Id est, while building a small wiki language I wrote this kind of rule :
text
    : (PURETEXT ( inlinenv | PURETEXT )*)
    | (inlinenv (PURETEXT | inlinenv)*)
    ;

In fact, I use the same sort of rule every time  I introduce text in a
inlinenv.

I'd like to know if there's a way to create a generic rule like the
following :
generic altern ((ARG1, ARG2))
    : (ARG1 (ARG2 | ARG1)*)
    | (ARG2 (ARG1 | ARG2)*)
    ;

And then reuse it, like an operator ?


Cheers,
Martin
