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
{
uint8_t revis开发者_开发知识库ionMajor;
uint8_t revisionMinor;
uint16_t checksum;
} ImageInfo;
ImageInfo gImageInfo; /* Placed at a specific address by the linker */
I would like to be able to take the binary generated by the C compiler/linker and parse this structure (and possibly modify it) with a Python script.
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".

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 ...
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 :)
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.
