Editing IDEs (section)

== Open Source ==

=== Haskell Language Server ===
In 2020, [[Haskell Language Server]] (HLS) was launched, which can be queried from most of the editors below. There are [https://github.com/haskell/haskell-language-server#configuring-your-editor installation instructions] for many of the editors below, so that is a good place to start, if you want to be using HLS.

=== [https://vscodium.com/ VSCodium]/[https://code.visualstudio.com/ Visual Studio Code] ===

VSCodium, and its proprietary counterpart Visual Studio Code, is a full featured IDE with several Haskell extensions available, such as Haskero, Haskelly and Haskell Language Server.

=== [https://github.com/rikvdkleij/intellij-haskell IntelliJ plugin for Haskell] ===
:See [http://www.haskell.org/pipermail/haskell-cafe/2014-October/116567.html the announcement of the plugin] and the [http://en.wikipedia.org/wiki/IntelliJ_IDEA Wikipedia article about IntelliJ].

=== [[Leksah]] (for Nix) ===
As of October 2019 maintained only with Nix. (See [commit history](https://github.com/leksah/leksah/commits/master))

:Leksah is an IDE for Haskell written in Haskell. Leksah is intended as a practical tool to support the Haskell development process. Leksah uses GTK+ as GUI Toolkit with the gtk2hs binding. It is platform independent and should run on any platform where GTK+, gtk2hs and GHC can be installed.

=== [http://atom.io Atom] ===

Atom is very similar to Sublime Text 2 (which is now discontinued). A huge [http://atom.io/packages package database] exists and two packages important to haskell developers are:
:* [https://atom.io/packages/language-haskell language-haskell] for haskell syntax highlighting.
:* [https://atom.io/packages/ide-haskell ide-haskell] for cabal-support, linting and ghc-mod utilities like type previewing.

=== [https://github.com/ndmitchell/ghcid Ghcid] - Very low feature GHCi based IDE ===

Not an editor per se, but a barebone IDE that will let you know compilation error any time you save a file. Doesn't integrate with any editor but works well with any of them + a terminal emulator.

=== [http://kdevelop.org/ KDevelop] ===
:This IDE supports many languages. For Haskell it currently supports project management, syntax highlighting, building (with GHC) & executing within the IDE.
