[antlr-interest] text associated with production

Wed Apr 16 08:02:56 PDT 2003

Tokens by default store the line and column of the start of the token.  So
keep your original file around and then when you have the first and last
tokens of the section you want to reproduce, simply use the line and column
to index into your file to get that region.

Yes, i want white spaces also, because i want the entire text of the
production. But i cud not understand the approach which wud give me the text
without white spaces. Please give some more information on that.

Stripped tokens shouldn't really be a problem. The original problem was to
get the text of the production, not the original stream. We ONLY want the
text of the matched tokens (or terminal nodes) for a rule.

Tokens that are skipped in the lexer will never be matched in the parser.
What does it matter if they are skipped?

But I think the problem with that approach would be that you will have some
things stripped out (like white space if you have that skipped)

One possible solution I think would be to get position of the first token
and position and length of the last token in a group, and then using that
information get the text data from the input.

Antlr doesn't do this for you. You need to collect the tokens and get the
text out of them yourself. Or build a tree in that rule and get the text
from the nodes in the tree.

Hi all
i want to get complete text associated with productions as we can do for
tokens. lets say following is a production
forStatement: forKeyword LPAREN initial semiColon 
final semiColon step RPAREN StatementBlock ;
i want to get the complete text associated with forStatement as we can do
for LPAREN and RPAREN.
Is there any such option in antlr.
Thanks and regards
Nitin Gupta
