Hi all,
Whenever I compile grammar where MyParser which extends TreeParser,
I get the following error. Any pointers why is it so? I am also
attaching the sub-rule at which this error is occuring.
---------------------------------------------------------------------
ANTLR Parser Generator Version 2.7.1 1989-2000 jGuru.com
error: Token stream error reading grammar
(s):antlr.TokenStreamRecognitionException: expecting ''', found '{'
BenhurPLSQL.g: error: rule classDef trapped: BenhurPLSQL.g:229:
unexpected token: (
error: aborting grammar 'BenhurPLSqlParser' due to errors
TokenStreamException: unexpected char: %
---------------------------------------------------------------------
Code --- I am getting error at the line #( (START_LABEL label_name
END_LABEL)?. I defined START_LABEL and END_LABEL as tokens and also
defined them in MyLexer
plsql_block:
#( (START_LABEL label_name END_LABEL)?
(("declare")? (declare_spec)+)?
("begin")?
seq_of_statements
("exception" exception_handler (exception_handler)*)?
("end" (label_name)? SEMI!)? )
;
Thanks
Benhur
