GHC

Haskell is an advanced purely functional programming language. The product of more than twenty years of cutting edge research, it allows rapid development of robust, concise, correct software. With strong support for integration with other languages, built-in concurrency, debuggers, profilers, rich ... [More] libraries and an active community, Haskell makes it easier to produce flexible, maintainable high-quality software. GHC is a state-of-the-art, open source, compiler and interactive environment for Haskell. [Less]

Darcs

Darcs is a free, open source source code management system. Every user has access to the full command set, removing boundaries between server and client or committer and non-committers. Darcs is easy to learn and efficient to use because it asks you questions in response to simple commands ... [More] , giving you choices in your work flow. You can choose to record one change in a file, while ignoring another. As you update from upstream, you can review each patch name, even the full "diff" for interesting patches. [Less]

xmobar

Xmobar is a minimalistic text based status bar. Inspired by the Ion3 status bar, it supports similar features, like dynamic color management, output templates, and extensibility through plugins.

Haskell base

The Haskell base library. Fundamental functions and data structures included with every Haskell system.

Pugs

An implementation of Perl 6 in Haskell, including the official Perl 6 test suite.

bytestring

A time and space-efficient implementation of byte vectors using packed Word8 arrays, suitable for high performance use, both in terms of large data quantities, or high speed requirements. Byte vectors are encoded as strict Word8 arrays of bytes, held in a ForeignPtr, and can be passed between C and Haskell with little effort.

HUGS

Hugs (Haskell User's Gofer System) (also Hugs 98) is a bytecode interpreter for the functional programming language Haskell. Hugs is the successor to Gofer, and was originally derived from Gofer version 2.30b.It offers fast compilation of programs and reasonable execution speed. It also comes ... [More] with a simple graphics library. Hugs is good for people learning the basics of Haskell, but is by no means a "toy" implementation. It is the most portable and lightweight of the Haskell implementations. Hugs deviates from the Haskell 98 specification[2] in several minor ways.[3] For example, Hugs does not support mutually recursive modules. The Hugs prompt accepts expressions for evaluation, but not module, type or function definitions. [Less]

parsec

Parsec is designed from scratch as an industrial-strength parser library. It is simple, safe, well documented (on the package homepage), has extensive libraries and good error messages, and is also fast.

lambdabot

Lambdabot is an IRC bot written over several years by those on the #haskell IRC channel. It also operates in an offline mode as a Haskell development tool, and embedded as an extension to ghci.

mtl

A monad transformer library, inspired by the paper Functional Programming with Overloading and Higher-Order Polymorphism, by Mark P Jones (http://web.cecs.pdx.edu/~mpj/pubs/springschool.html), Advanced School of Functional Programming, 1995.
