Haskelly

Haskelly is a Visual Studio Code extension that supports Haskell development.

Features

Code highlight
- Haskell (.hs and .lhs) and Cabal via automatic dependency on Haskell Syntax Highlighting.
Code snippets
- Structures : data, newtype, etc.
- Popular functions : map, fold, etc.
Type hovers
Jump to definition
- Jump to symbol definitions/declarations
Find references
- Find references within a module or depending modules. See limitations on #62
Code completion :
- Local functions and constants
- Standard library
- Imported modules
Integrated REPL, Build, Test and Run commands
- repl with GHCi
- build with stack
- run with runHaskell
- test current file prop_* properties with QuickCheck
- run full test suite with Stack test

Install the Haskelly VS Code extension.
Install Stack and add it to your PATH. Note that Stack folder naming conventions must be followed for it to work correctly, i.e. capitalizing folder names.
```
curl -sSL https://get.haskellstack.org/ | sh
```

Install Intero (code completion and type information), and QuickCheck (test suite)

stack install intero QuickCheck  # for a global installation
stack build intero QuickCheck # for a local installation

Haskelly is customizable (see Code > Preferences > Workspace Settings).
