[antlr-interest] Matching Dollar quoted strings

[Gokulakannan Somasundaram]

May be the question was not clear. Anyways, i have found the solution, so
thought of updating it.

fragment DOLQ_CONT : ALPH_CAP | ALPH_SMALL | ( '\u0200' .. '\u0377' ) | '_'
 | DIGIT;
fragment DOLQ_START : ALPH_CAP | ALPH_SMALL | ( '\u0200' .. '\u0377' ) | '_'
;

fragment DOLQ_DELIM_F1[ string& delim ]
@init{
ANTLR3_MARKER start = GETCHARINDEX();
}   : '$' (DOLQ_START) (DOLQ_CONT)* '$'
{
ANTLR3_MARKER stop = GETCHARINDEX();
delim.assign( (char*) start, stop - start );
};
fragment DOLQ_DELIM_F2 : '$' (DOLQ_START) (DOLQ_CONT)* '$' ;

fragment DOLQ_INSIDE: (~'$')+ | '$'
;

DOLQDELIM
@init{
string delim;
}: DOLQ_DELIM_F1[delim]
   DOLQ_INSIDE*
   { check_string_delim( delim, GETCHARINDEX() )  }? DOLQ_DELIM_F2
    ;

Thanks,
Gokul.
