It will probably a bit before I can add support to the parser. I'm
still trying to understand how src/mesa/shader/grammar works (and why
that was used instead of flex & byacc).
The ARB program parser is a bit of a mystery to me too.
If I'd rewrite the parsers toay I'd probably use lex/yacc. I originally
implemented my own recursive descent parsers for the NV extensions
because the language was pretty simple. Judging from LOC and
understandability, I don't think I did too bad.
How would using lex & yacc impact non-Unix builds? Meaning, will that
cause problems on Windows and Mac OS?
I suspect the generated files would be checked into CVS (like the
Python-generated files).
I'm also assuming the C code emitted by flex and bison on Linux is
pure C99 and doesn't have any gcc-isms.
