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) |]))

Known bugs: https://github.com/mchakravarty/language-c-inline/issues

• New in 0.7.6: (1) Record marshalling; (2) foreign pointer-class marshalling; (3) custom type marshallers. Generated _objc.m files now always include "HsFFI.h" (as the tool can generate type names declared in that header). Marshals Bool as BOOL. Marshal Int and Word to NSInteger and NSUInteger, 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.
