The annotation tool is a basic preprocessor.
Cheers,

Thanks folks,
I figured out how to do the two independent tree-walkers and one common
lexer+parser .g file for java using exportVocab/importVocab (I just didn't
understand these options before). Still need to se how to build C#
parser/lexer from the same grammar used by java tools. As suggested by Ric,
a pre-processor might be the best way.
Thanks again,
R.G.

Rupinder,
Have a look here at the ANTLR project here and especially the annotation
tool. The author uses it to maintain a single tree parser grammar for
multiple walks. You can adapt it for single grammar and multiple languages
too. You would probably want to move to a one-grammar-per-*.g-file
arrangement for this to work smoothly.

Incidentally, there is no guarantee that you will receive a response (let
alone a "satisfactory response") from any mailing list staffed by
volunteers. ;-)
Cheers,
Micheal

(I posted a query a week ago but didn't receive a satisfactory response.)
I have a grammar for logical-expressions from which I need to build the
following:
- Java lexer and parser
- C# lexer and parser
- Two java tree-walkers
- One C# tree-walkers
The two java tree-walkers are in independent projects; both projects do
depend on the project that defines the grammar (and contains lexer and
parser). C# lexer, parser and tree-walker can be in the same project. I
want to keep only one copy of the common.g file (one containing parser and
lexer sections). How do I this?
Grammar inheritance nor importVocab seem to be up to the task. Or am I
missing something?
Thanks,
R.G.
