Haskell

Haskell is a purely-functional programming language.

Compiler and interpreter

 * The probably most important and up-to-date Haskell-implementation is the Glasgow Haskell Compiler (GHC). You can install it with:


 * The package also includes an interpreter called GHCI (except on the ARM-architecture).


 * Furthermore, there's Hugs, an (meanwhile (almost) out-dated) interpreter for Haskell98. You can install it with:

Cabal
With cabal you can package and build libraries and programs. Install it with:

HLint
HLint checks and simplifies your haskell source code! Install it with:

Hoogle with local installation
The Hoogle ebuild is currently only available in the offical gentoo haskell overlay. So add that first.

In order to get the an offline installation of all hoogle data, you need to enable the "doc","hscolour" and "hoogle" use flag.

Enable the relevant use flags for hoogle to store all data local, and emerge hoogle

Haskell-Mode for Emacs
The Haskell-Mode for (X)Emacs makes programming easier; install it with

for GNU Emacs, or with

for XEmacs.

Then, you can configure it with.

Haskell-Mode for Vim
There's also a Haskell-Mode for Vim.
