Usage

Try It

1. Make sure your Emacs server is running. You can start the server like this

emacs --daemon

1. Focus an application window's text input. A text area in your browser will do.
2. Key the keyboard shortcut you've chosen for Emacs Anywhere
3. Write some text
4. Delete the frame (C-x 5 0, or :q if you use evil-mode). Emacs Anywhere will copy the text from the buffer "*Emacs Anywhere*" to clipboard, delete the buffer, switch focus to the window from step two and paste the buffers content into the text input.

Environment

The EA_EDITOR environment variable can be used to override the way emacsclient is run. For example, you could put the following statement into your .bash_profile.

export EA_EDITOR='emacsclient -a "" -c'

With the environment variable set, the invocation will look like this under the hood

emacsclient -a "" -c -e <elisp code>

You can prefix emacsclient with it's path if Emacs Anywhere can't find it in your PATH environment variable.

Commands

Command	Description
toggle-ea	If toggled to the "off" state, Emacs Anywhere will do nothing when the frame is deleted.

Variables

Variable	Description
ea-on	Boolean where t and nil denote the "on" and "off** states of Emacs Anywhere, respectively. The default value is t

Hooks

Hook	Function Signature	Description
ea-popup-hook	(app-name window-title x y w h)	Functions run after an Emacs Anywhere session starts.

Examples

;; Define a function or use a lambda of the same signature
(defun popup-handler (app-name window-title x y w h)
  ;; do stuff
  )

;; Hook your function
(add-hook 'ea-popup-hook 'popup-handler)

In your hook function you can do things like set the major mode based on the application name or window title...

(defun github-conversation-p (window-title)
  (or (string-match-p "Pull Request" window-title)
      (string-match-p "Issue" window-title)
      ;; ...
      ))

(defun popup-handler (app-name window-title x y w h)
  ;; set major mode
  (cond
    ((github-conversation-p window-title) (gfm-mode))
    ;; ...
    (t (markdown-mode)) ; default major mode
    ))

...or set the frame size and position to fit the bottom 400px of the window...

(defun popup-handler (app-name window-title x y w h)
  (set-frame-position (selected-frame) x (+ y (- h 400)))
  (unless (zerop w)
    (set-frame-size (selected-frame) w 400 t))
  ;; ...
  )

...or configure automation settings

(defun popup-handler (app-name window-title x y w h)
  (when (equal app-name "Terminal")
    ;; Tell Emacs Anywhere not to paste if launched from Terminal
    (setq ea-paste nil))
  ;; ...
  )
