[antlr-interest] Re: A question about extracting comments

[Fan Yang]

Hi Brian,

According to your suggestion, I have modified my lexter which is 
showing below. I think I used it in a wrong because there is an error 
like:

ANTLR Parser Generator   Version 2.7.1   1989-2000 jGuru.com
error: Lexer rule REM is not defined
MyVB.g:804: no definition of rule mREM

I'm sorry I ask you guys so many naive questions. 

Regards,

fan
/* ---  Test.g Begin  --- */

class MyLexer extends Lexer;
options {
 k=4;                	
 exportVocab=DIALECT;	
 testLiterals=false;
 caseSensitiveLiterals=false;
 caseSensitive=false;
}

tokens{
REM="rem";
}

COMMENT
  : (REM |'\'')
    (~('\n'|'\r'))* ('\n'|'\r'('\n')?)
    {std::cout<<$getText<<std::endl; $setType(ANTLR_USE_NAMESPACE     
(antlr)Token::SKIP); newline();}
  ;		
		
// Whitespace -- ignored
WS_ 
  :(' '
   |'\t'
   ){ _ttype = ANTLR_USE_NAMESPACE(antlr)Token.SKIP; }
  ;

/* ---  Test.g End  --- */
