lean-mode

Emacs mode for lean theorem prover

Requirement

lean-mode requires Emacs 24 and following (optional) packages which can be installed via M-x package-install.

To install them, you need to have MELPA in your package-archives. You can add it by evaluating the following elisp code:

(add-to-list 'package-archives
             '("marmalade" . "http://marmalade-repo.org/packages/") t)

Put the following elisp code on your emacs setup:

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "http://melpa.milkbox.net/packages/") t)
(package-initialize)
(when (not package-archive-contents) (package-refresh-contents))

;; Install required packages for lean-mode
(defvar lean-mode-required-packages
  '(company dash dash-functional flycheck whitespace-cleanup-mode fill-column-indicator))
(dolist (p lean-mode-required-packages)
  (when (not (package-installed-p p))
    (package-install p)))

;; Set up lean-root path
(setq lean-rootdir "~/projects/lean")
(setq-local lean-emacs-path
            (concat (file-name-as-directory lean-rootdir)
                    (file-name-as-directory "src")
                    "emacs"))
(add-to-list 'load-path (expand-file-name lean-emacs-path))
(require 'lean-mode)

;; Customization for lean-mode
(customize-set-variable 'lean-delete-trailing-whitespace t)
(customize-set-variable 'lean-flycheck-use t)
(customize-set-variable 'lean-eldoc-use t)
