Hello,
I'm trying to identify a DATE token in lexer, using the rule:
SEARCHVALUEDATE:
'\'' INT INT '/' INT INT '/' INT INT INT INT '\''
;
This works fine, although I would like to extend it in order to cover
cases such as: 30/5/2004, 1/5/2004 etc. I tried:
SEARCHVALUEDATE:
'\'' INT (INT)? '/' INT (INT)? '/' INT INT INT INT '\''
;
but the above completely !freezes! antlr.Tool while parsing my .g
file.
Any suggestions?
thanks!
