State of Haskell editor/IDE support

This chart describes the support level of each Haskell editor/IDE plug-in combination.

In most cases there is a main plug-in which acts as a base for the provided features.

Each known plug-in has an associated link and tooltip with its name.

Meaning of each level

Symbol	Support Level
?	Unknown, support is uncertain
⛔	Absent, you are on your own
🌱	Immature, only for early-adopters
🥈	Mature, suitable for most programmers
🏆	The best™ possible experience

Notes:

1. native support (probably minimal)
2. via main plug-in
3. this plug-in needs special config and/or system deps, refer to its documentation

Features

• Backend - The engine which makes some processing behind scenes to make most of the features available
• Easy to install - Is this setup easy to reproduce? Better when it is one-click and it just works, less when it needs special config, compile by hand, etc
• Syntax highlight
• Code Completion
• Error Reporting
• Lint
• Code Format
• Goto Def
• Find Usages
• Stepwise Debugger
• Doc. tooltips
• Snippets - Predefined and customizable templates for pieces of code you write often. For example, if you write case, an editor might provide a completion like

  case ___ of
    __ -> ___

• Hoogle
• REPL Integration - Be able to load/reload a file to e.g. ghci and provide interaction. Autocompletion and syntax highlighting are also welcomed.
• Build Command - Project compilation cycle can be started using the editor preferred way
