Description _ andrey_gubichev 2007-09-26 20:52:13 UTC 
ANTLR in C/C++ Pack doesn't generate correct Java classes for this grammar:


/*Sample grammar*/

header {
package org.netbeans.modules.fortran.generated;
import antlr.CommonToken;
import antlr.CharStreamException;
}

class Fortran77Parser extends Parser;
options {
    k = 2;
}

program :
	"";


class Fortran77Lexer extends Lexer;

protected NUM  : ('0'..'9') ;

protected INTVAL returns [int val=0]: (NUM)+ {val=Integer.parseInt($getText);} ;
Comment 1 Egor Ushakov 2007-10-30 14:26:46 UTC 
The problem is that current ANTLR does not generate correct return statements
in case of matching errors.
