[antlr-interest] C# example of "lexical filter mode" ??

[John Pool]

In The Definitive ANTLR Reference, at page 113 there is an example of a
lexer grammar, with at the end of the section the remark 'Lexical filter
mode is generally not used with a parser because the lexer yields an
incomplete stream of tokens.' 

 

I declared the fuzzy parser as follows: 

FuzzyParser lexer = new FuzzyParser (new ANTLRFileStream (sourceFileName));
// derives from Lexer class

Question: how do I 'execute' such a grammar lexer in C# without feeding it
into a parser? 

 

I tried downloading http://www.antlr.org/download/examples-v3.tar.gz, as
suggested in the book, but that URL won't open.
