ghc

GHC is a state-of-the-art, open source, compiler and interactive

environment for the functional language Haskell. Highlights: - GHC supports the entire Haskell 2010 language plus a wide variety of extensions. - GHC has particularly good support for concurrency and parallelism, including support for Software Transactional Memory (STM). - GHC generates fast code, particularly for concurrent programs. Take a look at GHC's performance on The Computer Language Benchmarks Game. - GHC works on several platforms including Windows, Mac, Linux, most varieties of Unix, and several different processor architectures. - GHC has extensive optimisation capabilities, including inter-module optimisation. - GHC compiles Haskell code either directly to native code or using LLVM as a back-end. GHC can also generate C code as an intermediate target for porting to new platforms. The interactive environment compiles Haskell to bytecode, and supports execution of mixed bytecode/compiled programs. - Profiling is supported, both by time/allocation and various kinds of heap profiling. - GHC comes with several libraries, and thousands more are available on Hackage.

Documentation tool for annotated Haskell source code

Haddock is a tool for automatically generating documentation from annotated Haskell source code. It is primary intended for documenting libraries, but it should be useful for any kind of Haskell code. Haddock lets you write documentation annotations next to the definitions of functions and types in the source code, in a syntax that is easy on the eye when writing the source code (no heavyweight mark-up). The documentation generated by Haddock is fully hyperlinked: click on a type name in a type signature to go straight to the definition, and documentation, for that type. Haddock can generate documentation in multiple formats; currently HTML is implemented, and there is partial support for generating DocBook. This package contains Haddock version 2.10.0.
