[antlr-interest] Problem with new lines

[Sharon Li]

Hello,

can anyone help me with this? 

1) My lexer can't seem to recognize newlines. Thanks.

/**************************** Lexer class ***************************************/

class ViewLexer extends Lexer;

options { 
    charVocabulary='\3'..'\377'; 
    filter=true;
    k = 4;
    defaultErrorHandler=false;
}

//protected SYMBOL : (SIGN|'%'|'/'|'.'|','|'*');
protected LETTER : ( 'a'..'z' | 'A'..'Z' ) ; 
protected DIGIT  : ( '0'..'9' ) ; 
protected SIGN   : ('-'|'+');

COLON : ':';
DOT     : '.';
COMMA : ',';

NUMERIC : (SIGN)? (DIGIT)+ ((DOT) (d:DIGIT)*)*
                ;

WORD : (LETTER) (LETTER|DIGIT)*
         ;
            
SL_COMMENT
        :       "//"
                (~('\n'|'\r'))* ('\n'|'\r'('\n')?)?
                {$setType(Token.SKIP); newline();}
        ;

//COMMENT : "/*" (options {greedy=false;} :.)* "*/" ;

NEWLINE : ('\r''\n')=> '\r''\n' 
        | '\r'{newline();}
        | '\n'{newline();}                  
        {
     newline(); 
     $setType(Token.SKIP);
    } 
        ;

WS      : (' '|'\t') { $setType(Token.SKIP); } ;

/**************************************** End of lexer *************************************/

2)  How can I check for comments. How do I write a parser rule that allows comments ?

Thanks a lot!!
