8. Release Notes

Important changes (especially those affecting the semantics of the tool) are documented in the following.

8.1 Version 0.12.0 "Springtime"

• Improved line pragma generation
• Works with GHC 6.3
• Builds on Mac OS X thanks to a patch by Sean Seefried

8.2 Version 0.11.5 "Powder Snow"

• Bug fixes
• Constant expression can now contain enumerators
• header label removed from context hooks
• WARNING: This version of c2hs may overwrite C header files in the current directory. More precisely, if a binding module with the name Foo.chs is processed, a header file with the name Foo.h is generated and will overwrite any file of the same name in the current directory or the directory specified via the -o option.
• Added support for CPP directives, including special treatment of conditions, and for inline C code; specification of a header file as an argument to c2hs is now option.
• GHC line pragmas are emitted into generated Haskell code
• Swap the order of reading the binding module and the C header (i.e., we now read the binding module first)

8.3 Version 0.10.17 "Altocumulus Stratiformis Perlucidus Undulatus"

• Worked around a bug in GHC 5.04.1
• Solaris-related fix
• Marshalling support for bit masks represented as enumeration types
• Added fun hooks
• as aliases can use ^ convert the orignal identifier with underscore2case
• In call hooks, the attributes `fun' was replaced by `pure' (`fun' is will still be recognised for a while to ensure backwards compatibility, but it's use is deprecated)
• GHC's package system is now supported
• If two import hooks add a type mapping for a pointer hook with the same name, the textual later one dominates.
• Bug fixes
• Support for bitfields (they are correctly handled when computing struct offsets and they can be accessed using set and get hooks)
• Some more support for GNU C extensions ("alignof" and better support "__attribute__")
• Added class hooks

8.4 Version 0.9.9 "Blue Ginger"

• Bug fixes
• Library names in foreign imports have been removed until the convention of the new FFI is implemented (they are currently silently omitted)
• Added sizeof hooks; sizeof of type names is now also supported in constant expressions
• Local prefix for enum hooks; courtesy of Armin Sander
• Added import hooks
• The documentation includes a description of binding hooks
• Added pointer hooks, which were derived from code for a similar feature by Axel Simon; this includes proper treatment of parametrised pointers
• Integrated deriving option for enum hooks, which was contributed by Axel Simon
• Adapted to GHC 5.0

8.5 Version 0.8.2 "Gentle Moon"

• Adaptation layer for legacy StablePtr interface
• Forgot to export FunPtr and associated functions from C2HS
• Forgot to export some names in C2HSDeprecated
• Added support for gcc's __builtin_va_list

8.6 Version 0.8.1 "Gentle Moon"

• Library adapted to New FFI; the old interface can still be used by importing C2HSDeprecated
• FFI Library specification added to the documentation

8.7 Version 0.7.10 "Afterthought"

• CygWin support; based on suggestions by Anibal Maffioletti Rodrigues de DEUS <anibaldedeus@email.com>
• IntConv instances for Int8, Word8, and Char

8.8 Version 0.7.9 "Afterthought"

• Debugged the stripping of prefixes from enumerators; prefixes are now generally stripped, independent of whether they can be stripped from all enumerators of a given enumeration type
• Comma now correctly required after underscoreToCase. WARNING: This breaks source compatibility with previous versions.

8.9 Version 0.7.8

• Provisional support for GHC 4.08
• Corrected constant folding

8.10 Version 0.7.7

Ignores any occurrence of #pragma.

8.11 Version 0.7.6

Bug fixes and support for long long.

8.12 Version 0.7.5

This is mainly a bug fix release. In particular, the space behaviour of C->Haskell has been significantly improved.

IMPORTANT NOTE: From this release on, library names in lib tags in context hooks should not contain a suffix (i.e., omit .so etc).
