# Haskell contribution layer for Spacemacs
|
|
|
|
|
|
|
|
This layer adds support for the [Haskell][] language.
|
|
The layer uses company-ghc for completetion.
|
|
|
|
**This layer is still not fully adapted for Spacemacs, it needs you, Haskell experts, to
|
|
improve it and make it consistent with the Spacemacs experience.**
|
|
|
|
## Install
|
|
|
|
To use this contribution add it to your `~/.spacemacs`
|
|
|
|
```elisp
|
|
(setq-default dotspacemacs-configuration-layers '(haskell)
|
|
"List of contribution to load."
|
|
)
|
|
```
