# Atomic Chrome for Emacs [](http://melpa.org/#/atomic-chrome) [](http://stable.melpa.org/#/atomic-chrome)
This is the Emacs version of [Atomic Chrome](https://github.com/tuvistavie/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](https://github.com/stsquad/emacs_chrome), 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](https://github.com/GhostText/GhostText) as browser extension.__
## Screencast
## Requirements
* Emacs: 24.3 or later
* OS: Tested on Windows and Linux
## Installation
### For Chrome
Atomic Chrome for Emacs shares browser extension with the one for [Atomic Chrome](https://chrome.google.com/webstore/detail/atomic-chrome/lhaoghhllmiaaagaffababmkdllgfcmc). Just install and setup it. Alternatively, you can use [Ghost Text](https://chrome.google.com/webstore/detail/ghosttext/godiecgffnchndlihlpaajjcplehddca) as browser extension.
### For Emacs
Atomic Chrome for Emacs can be installed via MELPA as below.
<kbd>M-x package-install [RET] atomic-chrome [RET]</kbd>
Then add the following lines to your `.emacs`.
``` emacs-lisp
(require 'atomic-chrome)
(atomic-chrome-start-server)
```
## Usage
1. Start Emacs.
2. Focus the text area you want to edit on the browser.
3. Press Atomic Chrome button on the tool bar.
4. Contet of the text area is opened in a new buffer of Emacs.
5. Edit content on Emacs buffer.
6. <kbd>C-c C-c</kbd> to finish editing, or the buffer killed if the browser closes the connection.
## Customization
### Set auto-update mode
Atomic Chrome for Emacs automatically reflects modifications to the browser by default as described above, but you can disable it by setting the variable below.
``` emacs-lisp
(setq atomic-chrome-enable-auto-update nil)
```
In this case, you can apply the modifications to the browser with <kbd>C-c C-s</kbd>
### Set major mode for editing buffer
The default major mode of editing buffer is `text-mode`. 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.
``` emacs-lisp
(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 like below.
``` emacs-lisp
(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.
``` emacs-lisp
(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` and `25`.
