I too have a looming spectre of a C++ analysis project, one of the goals of the project is to be able to efficiently process huge volumes (read GBs) of code. Given the current benchmarks of language.c compared to the g++ front end. I was thinking of using an existing C++ parser written in C++, probably Elsa[1]. Then use haskell to analyze the resulting AST.

From a parsing standpoint, C++ is a massive departure from C. Good luck though.

I am working on a research language that is a variant of C. I'd like to use Parsec as the parser.

Is there an existing Parsec parser for C or C++ (or Java) that could serve as a starting point?

Turns out that Language.C uses alex and happy. I'm looking to use Parsec. So back to the original question: Does anyone know of a C or java parser written using Parsec? - Roy On Thu, Jul 16, 2009 at 12:43 PM, Roy Lowrance wrote:

There is a C++ parser in C++, it may be of help : http://42ndart.org/scalpel/ It's a quite advanced WIP. On Fri, Jul 17, 2009 at 3:58 AM, Sterling Clover wrote:

A parser for JavaScript (admittedly a much simpler beast) is part of Brown's WebBits:

Cheers, Sterl.
