[antlr-interest] The filter option

[Jim Idle]

Marcos,

 

The C parser in the downloadable examples does something almost exactly like this. Why don't you start there as you will have a much more complete grammar that way too?

Subject: [antlr-interest] The filter option

 

Hello, I'm new to ANTLR, what I'm trying to do is a very simple parser to keep track of variables in a C/C++ source file and what function they are declared in (if any).
This is my grammar so far (I'm mostly just testing, it's not complete): 

grammar cvartracker;

options {
    language = CSharp;
    filter = true;

 

 
Nothing happens (ie, the System.Console.WriteLine() that is supposed to be called when there is a function or variable declaration is not called). If I turn the filter option off it does work, but then it complains about other things I'm not interested in. Anyone have any ideas on what I can do?
