Hello all!
I'm new to ANTLR and I'm trying to build a simple grammar that can recognize
strings like ('val'). I'm using ANTLRWORKS and it generates a rule for
string values with single quotes and I mapped the parenthesis to lexer
tokens:
RPAREN:'(';
LPAREN:')';
...
STRING
: '\'' ( ESC_SEQ | ~('\\'|'\'') )* '\''
;
Now, if I try to write the following:
rule : RPAREN STRING
and evaluate the input ('blah', I get an error in the interpreter. I have no
idea why, but I'm thinking the STRING rule is evaluating EOF and returning
an error.
Any ideas on how to make this work?
Regards,
