The hsc2hs program can be used to automate some parts of the
process of writing Haskell bindings to C code. It reads an
almost-Haskell source file with embedded special constructs, and
outputs a real Haskell file with these constructs processed, based
on information taken from some C headers. The extra constructs
provide Haskell counterparts of C types, values of C constants,
including sizes of C types, and access to fields of C structs.
For more details, see the
hsc2hs section
in the GHC User's Guide.
Changes
0.68.7
The C compiler is now assumed to be called cc instead of gcc
by default (#42)
Fix race condition when using response files (#30)
Add extra diagnostics when hsc2hs sub-process fails
and make TempFile creation fully atomic on Windows. See (#33)
0.68.6
Supports generation of response files to avoid system filepath
limits (#22, #23)
Fix non-deterministic failures for response file handlings (#29)
Temporary file removals on Windows are not a bit more reliable and should
throw less access denied errors. See #25 and
(#9775)
Accept a leading single quote for data constructor promotion (#13, #17)
Support MonadFail / base-4.13
Include template file as first header in hsc2hs generated C file (#28)
On Windows define __USE_MINGW_ANSI_STDIO to 1 instead of 0 when not already
defined in standard template header. This is a more modern default (#28)
0.68.5
Support response files regardless of which GHC hsc2hs was compiled
with (#15758)
Support for non-x86 platforms should be significantly more robust due to
improvements in hsc2hs’s assembly parser
Add support for haskell files that use a leading single quote for promoted
data constructors.
0.68.4
Add support to read command line arguments supplied via response files
(#13896)
