The Haskell Platform is a collection of software packages, tools and libraries that create a common platform for using and developing applications in Haskell. With the Haskell Platform, Haskell follows the same principle as Python: "Batteries included".[3] Since 2022, the Haskell Platform has been deprecated.[4]

Motivation
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.[3]
The Haskell Platform aims to unify Haskell development 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.
Packages included
Currently it consists of:[5]
- GHC, Haskell's flagship compiler
- The GHC-Profiler
- GHCi, GHCs bytecode-interpreter
- The GHCi-Debugger[6]
- Alex, a lexer generator, similar to Lex
- Happy, a parser generator, similar to Yacc[7]
- 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
Deployment
It is available for Ubuntu,[8] Arch Linux,[9][10] FreeBSD,[11] Gentoo Linux (x86-64 and x86),[12] Fedora,[13] Debian (stable)[14] and NixOS. One-click installers exist for OS X[15] (only Intel) and Microsoft Windows.[16]
Versions
Originally,[when?] the Haskell Platform aimed at a 6-months release cycle.[17] Starting with 7.10.2 which was released July 29, 2015, it has followed the release cycle of GHC and has since used the same version numbering scheme.[citation needed]
Deprecation
In 2022, the Haskell Platform was deprecated, and is no longer an actively supported or recommended way of installing Haskell.[18]
