Hi,
I have one lexical rule that contains another.
STRING: ( 'a'..'z'|'A'..'Z' )+
;
STRING_LITERAL
: '"'!
( '\\' .
| ~('"'|'\n'|'\r')
)*
( '"'!
| // nothing -- write error message
)
;
I'm using eclipse.
It's warning me that I have nondeterminism but I'm not using
STRING_LITERAL and STRING in the same parser rule.
What can I do to avoid this nondeterminism?
Tal.
