Elm setup on Debian

Installation

As a pre-requisite, ensure nodejs is installed; follow the steps mentioned below to install/setup Elm,

$ sudo npm install -g elm
$ sudo npm install -g elm-oracle elm-format elm-new

Editor Setup

Emacs

I followed Emacs setup for Elm and accordingly configured using cask.

~/.emacs.d/Cask

(depends-on "elm-mode")
(depends-on "flycheck-elm")
(depends-on "company")

~/.emacs.d/init.el

(defun my-elm-mode-hook ()
  (setq elm-sort-imports-on-save t)
  (setq elm-tags-on-save t)
  (setq elm-format-on-save t)
  (auto-complete-mode +1)

  (require 'company)
  (setq company-backends '(company-elm))
)

(add-hook 'elm-mode-hook #'elm-oracle-setup-completion)
(add-hook 'elm-mode-hook #'flycheck-elm-setup)
(add-hook 'elm-mode-hook 'my-elm-mode-hook)

(add-hook 'after-init-hook 'global-flycheck-mode)
(add-hook 'after-init-hook 'global-company-mode)
