Well, the lexer counts newlines (or CR+LF pairs) so as to provide a line count associated with each token it emits, but lines per se are not something that it otherwise deals in. Lines are, in effect, a completely separate partitioning of the input sequence and rarely correspond to a syntactically significant entity. So the answer is basically "no." However, the TokenStream interface can reconstruct the text of one or a sub-sequence of the tokens it has produced (based on ordinal indexes or particular Token instances produced by that TokenStream). You may be able to find a way to use that to reconstruct an input line or, more probably, a fragment of the input corresponding to some syntactically significant entity. > thanks for answering, > Michael Randall Schulz List: http://www.antlr.org:8080/mailman/listinfo/antlr-interest Unsubscribe: http://www.antlr.org:8080/mailman/options/antlr-interest/your-email-address --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "il-antlr-interest" group.
