|Developer(s)||Haskell Platform Infrastructure Team |
|Stable release||2012.4.0.0 / November 2012|
|Website||http://www.haskell.org/platform/ The Haskell Platform|
The Haskell Platform is a collection of software-packages, tools and libraries, which is to create a common platform for using and developing applications in Haskell. With the Haskell Platform, Haskell follows the same principle as Python: "Batteries included". As of 2010, development is no longer in the beta stage.
|“||The quality of a programming language itself is only one component in the ability of application writers to get the job done. Programming languages can succeed or fail based on the breadth and quality of their library collection.||”|
The Haskell Platform aims at unifying Haskell Developing tools into a single package, consisting of a compiler, compiling tools and many standard libraries, therefore making it easier to develop and deploy full-featured haskell-driven applications. Although Haskell is itself a powerful language to handle complex programming tasks, it is useless (or at least less useful compared to other programming languages) without a huge base of libraries allowing for building upon.
Packages included 
Currently it consists of:
- GHC, Haskell's flag-ship compiler
- The GHC-Profiler
- GHCi, GHCs bytecode-interpreter
- The GHCi-Debugger 
- Alex, a lexer generator, similar to Lex
- Happy, a parser generator, similar to Yacc
- Cabal, a package-manager
- Haddock, a documentation tool
- hsc2hs, a preprocessor for binding Haskell to C code, allowing C libraries to be used from Haskell
- various libraries, such as zlib, cgi and OpenGL
It is available for Ubuntu 10.10, Arch Linux,FreeBSD, Gentoo Linux (x86-64 and x86), Fedora, Debian (stable)  and NixOS. One-click installers exist for Mac OS X (only Intel) and Microsoft Windows (64-bit support currently alpha-only)
The Haskell Platform aims at a 6-months release cycle.
