How to define a rule for a version? [message #636343]

Eclipse User

I would like a rule for a version token like 1.0.20.23 or v1.0.20.23 or 1.0.20Beta.23

I'm trying the following, BUt the parser don't like my idea Wink

I'm not really a antlr, AST, compiler Freak Sad

Version: (INT|ID)*('.'(INT|ID)*)?;

Hi Fredy,

please give

Version hidden():
(INT ID? | ID) ('.' (INT ID? | ID))*;

a try.

Regards,
Sebastian
