An Emacs Lisp library for interacting with a haskell-ide-engine server using Microsoft's Language Server Protocol.
The library is designed to integrate with existing Emacs IDE frameworks (completion-at-point, xref (beginning with Emacs 25.1), flycheck, haskell-mode, intero, etc).
This package is still under development, and is not recommended for daily use.
Clone this repository and https://github.com/emacs-lsp/lsp-mode to suitable paths, and add
(add-to-list 'load-path "<path to lsp-haskell>")
(add-to-list 'load-path "<path to lsp-mode>")
(require 'lsp-haskell)
(require 'lsp-mode)
(add-to-list 'haskell-mode-hook #'lsp-mode)to your .emacs.
It needs the HIE server in your path, so
git clone https://github.com/haskell/haskell-ide-engine
cd haskell-ide-engine
stack install
