i use a definition so called
message : '"'.* '"';
that represents every little thing inside " " is message , terminals it works well with "lkjaldjfa kajf " something common but when i met "\n" it turns to a nightmare -- which cause infinitive loop ,eat up my memory .
I dont know why .. thanks
... it turns to a nightmare -- which cause infinitive loop, eat up my memory.
Hard to comment on that without being able to reproduce it.
However, the parser rule:
message : '"' .* '"';
matches the token '"' followed by zero or more other tokens ending with the token '"'.
Unless you have a very good reason to keep it as a parser rule (which I'd like to hear then), change it to a lexer rule:
Message : '"' .* '"';
which matches the character '"' followed by zero or more other characters ending with the character '"'.
Also see: Practical difference between parser rules and lexer rules in ANTLR?
