[antlr-interest] Variants of a grammar

[Marcel Schaible]

Hi,

I am currently reworking some old big YACC grammar files. Each of them 
(about 15 different YACC files with 5kB to 80Kb size) are describing a 
command language for a specific hardware device and share a lot of 
common rules. Now I was wondering if it is feasable to do some kind of 
object-oriented approach like put all shared rules in some kind of a 
base class and all the special command and command derivations in a 
derived class.  Another idea I am thinking of is using StringTemplate to 
generate the YACC grammar files.

Maybe one of you stumbled over a similar problem and has a nice solution 
and could push me in the rigth direction?

Thanks for sharing your thoughts in advance!

Marcel
