Parser for the Mathematica syntax?

Question

Is there a built parser that I can use from C# that can parse mathematica expressions?

I know that I can use the Kernel itself to parse an expression, and use .NET/Link

Answer 1

The mathematica grammar isn't well documented, true. But AFAIK, it is LALR(1) and likely LL(1); the bracketed /tagged syntax from gives the parser complete clues about what to expect next, just like LISP and XML.

The DMS Software Reengineering Toolkit does have a Mathematica grammar that has been used for real tasks. This includes MMa programs as well as pure expression forms.

That probably doesn't help you, since you want one in C#.

If you have access to the Kernal, I'd stick to that.
