[antlr-interest] Token rewrite

[xkrebstarx]

Hey guys,

I have a token in my grammar...

NUMBER    :        INTEGER | FLOAT
                  ;

where,

fragment INTEGER     :    '0'..'9'+|'#'('0'..'9'|'A'..'F'|'a'..'f')+ ;
fragment FLOAT        :
'0'..'9'+('.''0'..'9'+|(('e'|'E')('+'|'-')?'0'..'9'+'.''0'..'9'+)) ;

and I wanted to note the type in the AST, through rewrites and an imaginary
node, such as this...


NUMBER   :        INTEGER -> ^(INT_TAG INTEGER)
                          FLOAT -> ^(FLT_TAG FLOAT)
                 ;


How can I do something like this?

thanx,
xkrebstarx
