[antlr-interest] Parsing Question

[mzukowski at yci.com]

Something like

RULE: ('a'..'z')* ':'! ('a'..'z')*;

The ! tells it to not add that text to the token.

Hello,

	I'm attempting to parse something like:-

Comment: User , This is a comment
MachineID: System , fusion1

	I have worked out how to get the token split up with a lexer
that skips commas and newlines.  However I also want the system to
discard the colon character.  However if I use Token.SKIP then it
creates a new token for me - I don't want that - I just want the Lexer
to ignore the : and keep running on the same  token so that the parser
never sees the :.  However I can't work out how to do this.  

	Could anyone let me know of the correct syntax to use here.

	Thanks, in advance for your help.


Cheers,
