Hi all.
I have a problem with the lexer :
I have several lexer rules to detect some tokens. that's OK
but I want to create a rules for any token that do not match
the previous rules. In PCCTS there was a "precedence" in lexer rules
so that I could have a rule (.) at the end of all the rule and
if none of the previous one matched this one will.
I tryed to use the filter=OTHERTOKEN option (OTHERTOKEN is a private
rule) in the antlr parser but this prevent the lexer to throw
exception if the char do not match any rules and match OTHERTOKEN but
do not create token in the token stream
Is there a way to handle this without writing an long complex rule for
OTHERTOKEN?
TIA,
Franck
