well, I think for terminals a full fledged parser framework is a bit heavyweight,
don't you think ? Each parser has a simple grammer to know about, so I think
a simple table or even regex based one would be ok. (Each concrete parser could
use its own method, all that is necessary is that all parsers provide a unified
abstract interface to the stream, or vice versa).
With respect to antlr, I already had a look at it. Do you have any experience
with it ?
I'm asking since I started a source code analysis tool
(http://Synopsis.sourceforge.net)
and I'm looking into openC++ as a C++ parser front end, but I'm only partly
successful. Can you provide some hints as to how to build a C++ parser with
antlr which is able to produce an Abstract Syntax Tree ? Or is the C++ grammar
too complex for a general parser framework ?
My main goal with Synopsis is to produce documentation, but even source code
navigation tools should be possible...
