Parsing C

[Sean Ross]

Hi.
PLY does not generate an AST(although it does include some examples in the
documentation on how to make your own). SPARK, however, can be used to
generate an AST automatically, but you'll have to code the scanner and
parser. The PLY C example will probably be a useful guide for that.

I'm using SPARK now for a small language and I've been pleased with how easy
it's been to work with. So, I'd like to recommend it. For one thing, you can
make your C parser class as a subclass of GenericASTBuilder and the parser
will build your tree for you, just specify the grammar(which you can get
from PLY).

OK, then, good luck, and have fun
Sean
