## What it is
An IntelliJ IDEA plugin providing Haskell language support, built on Stack and external tools like GHC and Hoogle. It offers syntax highlighting, error highlighting, code completion, navigation, refactoring, and type information for Haskell projects.

## Use cases
- edit haskell code in intellij idea
- syntax highlighting for haskell files
- navigate to haskell function definitions
- get type info for haskell expressions
- code completion for haskell
- import existing stack projects into intellij
- rename haskell identifiers safely

## When to choose
- you use IntelliJ IDEA or other JetBrains IDEs and write Haskell
- you want an IDE experience with navigation, completion, and type info for Stack-based Haskell projects

## When to avoid
- you use VS Code or another editor (HLS-based tooling may fit better)
- your project does not use Stack
- you need GHC versions older than 8.2.2

## Facets
- artifact type: plugin
- maturity: active

- domain: developer-tools, text-editors, programming-languages
- platform: cross-platform, editor-plugin
