language-c-inline: Inline C & Objective-C code in Haskell for language interoperability
This library provides inline C & Objective-C code using GHC's support for quasi-quotation. In particular, it enables the use of foreign libraries without a dedicated bridge or binding. Here is a tiny example:
nslog :: String -> IO () nslog msg = $(objc ['msg :> ''String] (void [cexp| NSLog(@"Here is a message from Haskell: %@", msg) |]))

New in 0.7.10: Distinction between
Class
(NSObject pointers) andStruct
(C pointers) in both hints and marhsallers.New in 0.7.9: C wrapper names include the filename to disambiguate linker symbols.
New in 0.7.8: (1) Record marshalling; (2) foreign pointer-class marshalling; (3) custom type marshallers; (4) marshall raw pointer types. Generated _objc.m files now always include "HsFFI.h" (as the tool can generate type names declared in that header). Marshals
Bool
asBOOL
. MarshalInt
andWord
toNSInteger
andNSUInteger
, respectively.New in 0.6.0: Introduction of explicit marshalling hints (for more flexibility and support of GHC 7.8's untyped Template Haskell quotations)
New in 0.5.0: Marshalling of numeric types
New in 0.4.0: Maybe types are marshalled as pointers that may be nil & bug fixes.
New in 0.3.0: Boxed Haskell types without a dedicated type mapping are marshalled using stable pointers.
New in 0.2.0: Support for multiple free variables in one inline expression as well as for inline code returning
void
.New in 0.1.0: We are just getting started! This is just a ROUGH AND HIGHLY EXPERIMENTAL PROTOTYPE.
