Instant Github-flavored Markdown/Org preview using Grip (GitHub Readme Instant Preview).

Prerequisite

Install

Manual

From melpa, M-x package-install RET grip-mode RET.

;; Make a keybinding: `C-c C-c g'
(define-key markdown-mode-command-map (kbd "g") #'grip-mode)

;; Or start grip when opening a markdown/org buffer
(add-hook 'markdown-mode-hook #'grip-mode)
(add-hook 'org-mode-hook #'grip-mode)

Use-package

;; Use keybindings
(use-package grip-mode
  :ensure t
  :bind (:map markdown-mode-command-map
         ("g" . grip-mode)))

;; Or using hooks
(use-package grip-mode
  :ensure t
  :hook ((markdown-mode org-mode) . grip-mode))

Run M-x grip-mode to preview the markdown and org buffers in the embedded webkit browser if Emacs supports (built with --with-xwidgets), or in the default browser (Chrome, Firefox, etc.).

ox-gfm is optional, but it brings better rendering for org files.

Enjoy! 😄

Customize

Run M-x customize-group RET grip RET or set the variables.

;; Path to the grip binary
(setq grip-binary-path "/path/to/grip")

;; You can use this variable to define another browser
;; to use when loading previews. By default this value is `nil`
;; meaning use default browser defined by your system
(setq grip-url-browser "custom_browser")

;; If you want to pass arguements to your custom browser then use
(setq grip-url-args '("arg1" "arg2" "etc"))

;; A GitHub username for API authentication
(setq grip-github-user "")

;; A GitHub password or auth token for API auth
(setq grip-github-password "")

;; When nil, update the preview after file saves only, instead of also
;; after every text change
(setq grip-update-after-change nil)

;; Preview hostname
(setq grip-preview-host "localhost")

;; Use embedded webkit to previe
;; This requires GNU/Emacs version >= 26 and built with the `--with-xwidgets`
;; option.
(setq grip-preview-use-webkit t)

  (setq grip-github-user (car credential)
        grip-github-password (cadr credential)))
