Atomic Chrome for Emacs
This is the Emacs version of Atomic Chrome which is an extension for Google Chrome browser that allows you to edit text areas of the browser in Emacs. It's similar to Edit with Emacs, but has some advantages as below with the help of websocket.
- The input on Emacs is reflected to the browser instantly and continuously.
- You can use both the browser and Emacs at the same time. They are updated to the same content bi-directionally.
Since v2.0.0, Atomic Chrome for Emacs supports Ghost Text as browser extension, bringing compatibility with Firefox, too.

. You can change the major mode manually. If you want to use a different major mode as the default, set atomic-chrome-default-major-mode
like below.
(setq atomic-chrome-default-major-mode 'markdown-mode)
Additionally, you can use atomic-chrome-url-major-mode-alist
to choose the major mode for a specific website based on the page URL (or, with GhostText, URL hostname) like below.
(setq atomic-chrome-url-major-mode-alist
'(("github\\.com" . gfm-mode)
("redmine" . textile-mode)))
This is an association list of regexp and major mode function. If the page URL matches to on of the regexp, the corresponding major mode is selected.
Select editing buffer style
You can select the style of opening the editing buffer by atomic-chrome-buffer-open-style
like below.
(setq atomic-chrome-buffer-open-style 'frame)
Available values are the followings.
full
: Open in the selected window.split
: Open in the new window by splitting the selected window (default).frame
: Create a new frame and window in it.
frame
is available only when you are using Emacs on some window system.
If you select frame
, you can also set the width and height of the frame with atomic-chrome-buffer-frame-width
and atomic-chrome-buffer-frame-height
. Their default values are 80

like below.
(setq atomic-chrome-extension-type-list '(atomic-chrome))
