How to parse a C header file?

Question

Does anyone know a spiffy way to use C header files in Python? For example I have a C program that includes a global variable:

typedef struct ImageInfo
{
            


        

Answer 1

For the same purpose I'm considering pyclibrary, it is not a complete C parser but it is aimed at parsing C header files, so it is much easier to use than pycparser or some gccxml-based parser: although weakly documented, just try CParser.py testHeader.h and you'll see how it works.

Depends on pyparsing and, as far as I understand, it is pure python.

Answer 2

Have a look at this C++ header parser written in Python. You can also write your own parser using any of these tools:

• pyparsing
• ply

• lepl

  and a lot more ...

Answer 3

This was mentioned on SO yesterday; I haven't had a chance to check it out more thoroughly yet, but I'm meaning to. The pycparser, a "C parser and AST generator written in Python".

Answer 4

Take a look at pygccxml. I use it to build in-memory graphs of my C / C++ source code that I can use as the basis for many code generation tasks.

PS: When I first started out with Python based code-generation I actually tried to write a parser myself: save yourself the pain and don't even go there! (looks like your are clued up already though...) pygccxml is everything you want and more :)
