lean-mode

Emacs mode for lean theorem prover

Requirement

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

The following packages are optional but we recommend to install them to use full features of lean-mode.

Install

Put the following elisp code on your emacs setup (e.g. .emacs.d/init.el):

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

;; Install required/optional packages for lean-mode
(defvar lean-mode-required-packages
  '(company dash dash-functional flycheck whitespace-cleanup-mode
    f fill-column-indicator s lua-mode mmm-mode))
(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)

If experience a problem reading unicode characters on emacs, consider having the following setup:

(when (member "DejaVu Sans Mono" (font-family-list))
  (set-face-attribute 'default nil :font "DejaVu Sans Mono-11"))

Contribution

Contribution is welcome!

If your contribution is a bug fix, create your topic branch from master. If it is a new feature, check if there exists a WIP(work-in-progress) branch (vMAJOR.MINOR-wip). If it does, use that branch, otherwise use master.

Install Cask if you haven't already, then:

$ cd /path/to/lean/src/emacs
$ cask

Run all tests with:

$ make
