* Description
This layer provides some integration with the Google Chrome browser.

** Features:
- Edit text boxes with Emacs using [[https://github.com/stsquad/emacs_chrome][edit-server]]
- Write markdown in Emacs and realtime show in chrome using [[https://github.com/mola-T/flymd][flymd]]
- gmail message mode uses standard markdown keybindings

* Install
** Layer
To use this configuration layer, add it to your =~/.spacemacs=. You will need to
add =chrome= to the existing =dotspacemacs-configuration-layers= list in this
file.

** Chrome extension
[[https://github.com/stsquad/emacs_chrome][edit-server]] is a server that responds to edit requests sent Chrome via the
Google Chrome extension [[https://chrome.google.com/webstore/detail/edit-with-emacs/ljobjlafonikaiipfkggjbhkghgicgoh][Edit with Emacs]]. You have to install this extension.

More information can be found on [[http://www.emacswiki.org/emacs/Edit_with_Emacs][Emacs Wiki]].

The edit server is configured to start automatically when Spacemacs starts.

* Configuration
Use =edit-server-url-major-mode-alist= to choose a major mode initialization
function based on =edit-server-url=, or fall back to
=edit-server-default-major-mode= that has a current value of =markdown-mode=.

#+BEGIN_SRC emacs-lisp
  (defun dotspacemacs/user-config ()
  ;; Open github text areas as org buffers
  ;; currently they are opened as markdown
    (setq edit-server-url-major-mode-alist
        '(("github\\.com" . org-mode))))
#+END_SRC

To change frame defaults (width, height, etc. use =edit-server-new-frame-alist=)

#+BEGIN_SRC emacs-lisp
  (add-to-list 'edit-server-new-frame-alist '(width  . 140))
  (add-to-list 'edit-server-new-frame-alist '(height . 60))
#+END_SRC

If you want Emacs to switch focus to Chrome after done editing, you can utilize
=edit-server-done-hook=.

Emacs cannot control focus of windows for external apps, so you need to use some
sort of command line window manager like =wmctrl=.

The following example works on OS X:

#+BEGIN_SRC emacs-lisp
  (add-hook 'edit-server-done-hook (lambda () (shell-command "open -a \"Google Chrome\"")))
#+END_SRC

* Key bindings

| Key Binding | Description |
|-------------+-------------|
| ~SPC a F~   | flymd-flyit |

*Note:* You need to kill all google chrome process before using =flymd-flyit=.
