Hello,
Following is a lexer rule to match quoted string that allows backslash
escape sequence.
STRING
: '"' ( options {greedy=false;} : ( ~ '\\' | '\\' . ) )* '"'
;
It seems to work. But if you put the '*' operator inside the subrule
like this:
STRING
: '"' ( options {greedy=false;} : ( ~ '\\' | '\\' . )* ) '"'
;
It eats up everything to EOF.
It's as if the greedy option applies to the ((subrule)*) instead of the
subrule itself, and only if the subrule is suffixed with '*' operator
(or with '+') externally (as in (subrule)*).
To my eyes, the second version seems the "correct" one.
Thoughts?
