obs-websocket-el

Totally bubblegum-and-string at the moment.

You’ll need Open Broadcaster Software and the obs-websocket plugin for it. Set it up in Tools > WebSockets Server Settings. Set a password there.

You will also need websocket, which is available from GNU ELPA. You can install it with M-x package-install RET websocket RET.

You will probably be able to use M-x obs-websocket-connect to connect to your OBS server. I have no idea if it will work for anyone but me, though. Good luck!

You can use (setq obs-websocket-password "yourpasswordhere") in your Emacs configuration file so that it won’t prompt you for the password.

Here’s my config. It uses use-package and hydra.

(use-package websocket)
(defun my/twitch-message (text)
  (interactive "MText: ")
  (with-current-buffer
      (get-buffer-create "Twitch message")
    (erase-buffer)
    (insert text)
    (goto-char (point-min))))
(use-package obs-websocket
  :config
  (defhydra my/obs-websocket (:exit t)
    "Control Open Broadcast Studio"
    ("c" (obs-websocket-connect) "Connect")
    ("d" (obs-websocket-send "SetCurrentScene" :scene-name "Desktop") "Desktop")
    ("e" (obs-websocket-send "SetCurrentScene" :scene-name "Emacs") "Emacs")
    ("i" (obs-websocket-send "SetCurrentScene" :scene-name "Intermission") "Intermission")
    ("v" (browse-url "https://twitch.tv/sachachua"))
    ("m" my/twitch-message "Message")
    ("t" my/twitch-message "Message")
    ("<f8>" my/twitch-message "Message") ;; Then I can just f8 f8
    ("sb" (obs-websocket-send "StartStreaming") "Stream - begin")
    ("se" (obs-websocket-send "StopStreaming") "Stream - end"))
  (global-set-key (kbd "<f8>") #'my/obs-websocket/body)
  :load-path "~/code/obs-websocket-el" :ensure nil)

Better installation instructions will eventually be written by someone, if anyone wants to actually maintain this.
