[antlr-interest] NEWBIE: Parsing log files

[cunctator69]

I've got what seems to be a fairly straightforward
problem, but I've had no luck solving it, nor have I
found an answer in the fairly copious antlr docs. I'm
sure it's there, but I don't think I'm recognizing it.

I'm trying to use antlr to parse a Log4J log file. The
problem is that I'm trying to match something like:

// from the parser
startRule
	:	(record)+
	;
record 
	: 	date time priority DASH! message
	;

and message represents everything from DASH to the end
of the line. I tried a rule like:

message
	:	UP_TO_EOL
	;

// lexer

UP_TO_EOL
	:LETTER (options {greedy=false;} :.)* '\n'
	;

but that conflicts with:

WORD
	:	('a'..'z' | 'A'..'Z')+
	;

As I said, it seems pretty straightforward. I
understand why I'm getting the ambiguity warning -- I
just can't figure out how to build a single
unambiguous token that matches from an arbitrary point
to the end of the line. I would appreciate any
guidance offered.

Thanks,
Alex
