Sam,
I understood the answer, but we're talking novice here - if the front
end of my grammar looks like this:
prog: body EOF!
;
body :
parts -> ^(BODY parts)
;
parts :
( (stat
| ifStat
| switchStat
| whileStat
| forStat) )*
;
stat:
(ID OPENP actualParameters CLOSEP DOT ID GETS)
=> str=ID OPENP actualParameters CLOSEP DOT fld=ID GETS expr
-> ^(GETS ?????? ^(STRUCTA $str $fld actualParameters) expr)
| (ID OPENP actualParameters CLOSEP DOT OPENP)
=> str=ID OPENP actualParameters CLOSEP DOT OPENP var=ID
CLOSEP GETS expr
-> ^(GETS ???????? ^(STRUCTAV $str $var actualParameters) expr)
// etc
;
how would I insert the line number at the ???????

It seems that the parse tree generated by the parser has a data field
'line' that seems to correspond to the source line when parsing. How
do i access that to include the line number in the tree generated by
my grammar?

Both the Tree and Token interfaces have a method getLine().
