[antlr-interest] Can I embed the Antlr version number in my generated code using some kind of macro?

[Tony.Gray at ca.schneider-electric.com]

Thanks Andrew - after I'd posted, I did some poking around that led me 
right to CSharp2.stg.  It's very readable, and I thought about modifying 
it, but as you (and Yoda) pointed out, "Once you start modifying your 
distro, forever will it dominate your upgrades".   If there were an actual 
error I was trying to fix, sure, but this one isn't worth it.

Thanks for your help!

You would have to modify the string template for the CSharp2 target in the
antlr-3.2.jar file.
It lives at antlr-3.2_jar\org\antlr\codegen\templates\CSharp2\CSharp2.stg
You can update if you have a copy of winzip handy.  Just unzip, update the
stg. file and rezip.
Of course that change will be null and void with the next version of antlr
which will have a new version of the string template.  That is how to 
update
the generated code however.

Hope that helps.
