c2hs: C->Haskell FFI tool that gives some cross-language type safety

[ development, gpl, program ] [ Propose Tags ]

C->Haskell assists in the development of Haskell bindings to C libraries. It extracts interface information from C header files and generates Haskell code with foreign imports and marshaling. Unlike writing foreign imports by hand (or using hsch2s), this ensures that C functions are imported with the correct Haskell types.

               C->Haskell - Haskell Interface Generator              -*-text-*-
               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

C->Haskell is a interfacing tool that eases Haskell access to C libraries.
The tool gets information about the C data type definitions and function
signatures by analysing the C header files of the library.  It uses this
information to compute the missing details in the template of a Haskell
module---called the binding file---that implements a Haskell binding to the C
library.  Hooks embedded in the binding file signal where, which, and how C
objects are accessed from Haskell.  The Haskell code in the binding file
determines Haskell types signatures and marshaling details.  Further
information is at

  http://www.cse.unsw.edu.au/~chak/haskell/c2hs/
