md4rd - Mode for Reddit


Read Reddit interactively from within Emacs.

Why the odd name?

See the Reddit TOS/API guide - anything named after that trademark (reddit) must be prefixed with a 'for', so 'mode for reddit' is fine, however 'reddit mode' is not.

Hopefully you can help your friends find this package as their reddit need's dictate :)


Clone the repo, then in your Emacs init file:

(add-to-list 'load-path "/path/to/repo")
(require 'md4rd)
(md4rd) ;; to launch it

Signing in / authenticated features

UPDATE 2023-06-03

Reddit is planning to charge API authors for access - I'm not altruistic enough to pay for all of you to have login features (upvote/downvote) when this is primarily a reader mode, which doesn't require login.

You can still use login features, but will require setting up your own API account with Reddit and configuring OAUTH2 (many guides for this, I won't detail here).

Essentially, you'll need to set these variables correctly in your Emacs configs:

(defvar md4rd--oauth-client-id "abc123"
  "The client ID that links this up to the OAuth endpoint.")

(defvar md4rd--oauth-redirect-uri
  "http://localhost:12345" ; Or some world facing domain you use for this
  "The Oauth2 redirect_uri that links this up to the OAuth endpoint.")

OAuth integration was just finished, and you can invoke the sign in with:

M-x md4rd-login

This will pop up a permission grant page on, which will forward you to my site (reddit requires this redirection and it is easier than running a localhost:port setup for each Emacs user who may or may not have the port open, as it must match one single redirect_uri on the app level config being used for OAuth).

After you see the code, simply paste it into your Emacs' minibuffer prompt, which will have been waiting for you to finish the process.

It will then fetch your oauth access token and refresh tokens.

Bring on the upvotes!


If you're signed in, you can highlight a post in the *subreddit* buffer and upvote or downvote as you like.

Setting your default reddits

You can subscribe to different reddits by customizing your rm::subreddits-active variable.

(setq md4rd-subs-active '(lisp+Common_Lisp emacs prolog))

(A cool feature of reddit is you can view multiple reddits combined with the + concatenation).

Re-authenticating your session on sign in and every hour

Add something like this into your config (sample using use-package):

(use-package md4rd :ensure t
  (add-hook 'md4rd-mode-hook 'md4rd-indent-all-the-lines)
  (setq md4rd-subs-active '(emacs lisp+Common_Lisp prolog clojure))
  (setq md4rd--oauth-access-token
  (setq md4rd--oauth-refresh-token
  (run-with-timer 0 3540 'md4rd-refresh-login))


If you hate the really wide text / no default indent, try this new function + hook combo.

(add-hook 'md4rd-mode-hook 'md4rd-indent-all-the-lines)


See the following (shown in emacs -nw mode):

Note - this first one is with the indent-all-the-lines hook enabled: indented subreddit comments
