Installation

Using MELPA

This package can be obtain from MELPA or MELPA Stable. The main branch is continuously deployed to MELPA, and released versions are deployed to MELPA Stable.

M-x package-install [RET] ponylang-mode [RET]

Right now ponylang-mode doesn't take a lot of configuration (i.e. it's too simple to need any). If you want to make sure your indentation matches that in the ponyc project's examples, you can use something like this:

(require 'ponylang-mode)
(setq ponylang-banner 1) ;; 0: None 1: Word (Default) 2: Horse 3: Knight
(define-key ponylang-mode-map (kbd "<f6>")  'ponylang-menu)

• Customize banner:

(setq ponylang-banner "¯\\_(ツ)_/¯")

(setq ponylang-banner "
             _|\\ _/|_,
           ,((\\\\``-\\\\\\\\_
         ,(())      `))\\
       ,(()))       ,_ \\
      ((())'   |        \\
      )))))     >.__     \\
      ((('     /    `-. .c|
              /        `-`'")

Using use-package

(use-package ponylang-mode
  :ensure t
  :init
  (setq ponylang-banner 1)
  :config
  :bind-keymap
  ("<f6>" . ponylang-menu))
