Convert C API header files to .hsc and .hsc.helper.c files https://github.com/jwiegley/c2hsc

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
Converts C API header files to
Usage: c2hsc --prefix=<Lib Prefix> <FILE>.h
This will create
<FILE>.hsc.helper.c if the header file
contains inline functions.
For example, in
hlibgit2 on the Mac I'm using:
c2hsc --prefix=Bindings.Libgit2 --cppopts=-U__BLOCKS__ \ libgit2/include/git2/tree.h
Need to output vararg functions with a comment mentioning they are not translatable to the Haskell FFI
Also, please note that this tool will never be 100% accurate. It cannot
translate macros, or anything related to the preprocessor, for example. It
often misses necessary
#include files, and will get them wrong in any case
if preprocessor conditionals are involved.
The goal of
c2hsc is to solve the hardest 80% of the problem of creating an
FFI library. The remaining 20%, plus validation of the results, is an
exercise necessarily left to the user.
