[antlr-interest] C/C# pre-processor

[Kamal Verma]

I mean both.

A pre-processor using ANTLR which is part of ANTLR factory or utilities 
classes. Or some other set of pre-processor techniques that can be used 
along with ANTLR.

In general, preprocessing is 1st step that a language developer (one who 
works with language) needs before lexing. As I learnt from the antlr 
discussions and other on the web I found various strategies folks has 
implemented. There is no one set way to do it.

I think for ANTLR to be more useful tool it is needed that we have a nice 
way to pre-process a langauge. Also, since everyone says it is not that 
complex, we can code these preprocessor utilites as factory classes once and 
make it part of standard ANTLR runtimes.

Wouldn't it be nice if we are able to do following,

----8<----
Stream s = File.OpenText("somefile.code");
CSPreprocessor pp = new CSPreprocessor(s, "DEBUG;CPP;SOMECONST");
MyLexer lexer = new MyLexer(pp);
MyParser parser = new MyParser(lexer);
parser.main();
----8<----
