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

** Configuration
*** Configure the Default Input Method(配置默认中文输入法)
The default Chinese input method is =Chinese-pyim=, if you are a Wubi(五笔) user,
you could set the variable =chinese-default-input-method= to =wubi=:

#+BEGIN_SRC emacs-lisp
  (setq-default dotspacemacs-configuration-layers '(
    (chinese :variables chinese-default-input-method 'wubi)))
#+END_SRC

*** Configure the =Chinese-pyim= Input Method(配置中文拼音输入法)
The first time you use =Chinese-pyim=, you need to install the lexicon(词库)
file. Call =pyim-dicts-manager= to open up the settings buffer and
press =i e= to install the default lexicon. The lexicon is about 20MB, so you
should be patient when downloading starts. After the lexicon file is downloaded,
just press =s= to save and =R= to restart configuration.

*** Configure =chinese-conv= (配置简繁转换)
The =chinese-conv= package requires either [[https://github.com/BYVoid/OpenCC][opencc]] or [[https://github.com/xiaoyjy/cconv][cconv]] installed.

By default, =opencc= will be used as the backend, set

#+BEGIN_SRC emacs-lisp
  (setq-default dotspacemacs-configuration-layers '((chinese :variables
                                                             chinese-conv-backend "cconv")))
#+END_SRC

to use =cconv= as the backend.

There is no default key binding for the conversions. Run

=M-x chinese-conv=

to replace arbitrary input, or

=M-x chinese-conv-replace=

to replace the current selection in-place.

*** Enable fcitx
#+BEGIN_SRC emacs-lisp
  (setq-default dotspacemacs-configuration-layers '((chinese :variables
                                                             chinese-enable-fcitx t)))
#+END_SRC

If you don't need to type Chinese in minibuffer, you can temporarily disable fcitx in the minibuffer
with the following configuration.

#+BEGIN_SRC emacs-lisp
  (fcitx-aggressive-setup)
#+END_SRC

**** Requirement
***** Linux
You need to install =fcitx= and =fcitx-remote= on your machine.

***** Mac OS X
We don't have a =fcitx= in OS X yet but we already added an emulation called
=fcitx-remote= to make you happy with other Chinese input-methods.

You can install [[https://github.com/CodeFalling/fcitx-remote-for-osx][fcitx-remote-for-osx]] from homebrew.

#+BEGIN_SRC shell
  brew install fcitx-remote-for-osx --with-input-method=baidu-pinyin
#+END_SRC

=--with-input-method=baidu-pinyin= means install for Baidu-pinyin Input Method.

You can use =brew info fcitx-remote-for-osx= to get more options info for input
method support.

#+BEGIN_EXAMPLE
  --with-input-method=
    Select input method: baidu-pinyin(default), baidu-wubi, sogou-pinyin, qq-wubi, squirrel-rime, osx-pinyin
#+END_EXAMPLE

***** Windows
In order to use =fcitx.el= in Windows, you should install [[https://github.com/cute-jumper/fcitx-remote-for-windows][fcitx-remote-for-windows]].

*** Enable YouDao(有道) Dictionary(激活有道字典)
The YouDao Dictionary is disabled by default, if you want enable it.
You should set =chinese-enable-youdao-dict= to =t=.

#+BEGIN_SRC emacs-lisp
  (setq-default dotspacemacs-configuration-layers '((chinese :variables
                                                             chinese-enable-youdao-dict t)))
#+END_SRC

*** Set monospaced font size(设置等宽字体）
If you are mixing Chinese script with Latin script, the text is not perfectly
aligned in org table. That's because normally the Chinese font size is not equal
to the Latin font size. You could call =spacemacs//set-monospaced-font= with
your own Chinese font name in =dotspacemacs/user-config= function.

Example configuration:

#+BEGIN_SRC emacs-lisp
  ;; Note: The Hiragino Sans GB is bundled with MacOS X.
  ;; If you are not using MacOS X, you should change it to another Chinese font name.
  (spacemacs//set-monospaced-font   "Source Code Pro" "Hiragino Sans GB" 14 16)
#+END_SRC

*** Enable/Disable ace-pinyin in =avy-goto-char=
You can use =avy-goto-char= with pinyin supported by default, if you want to
disable it. You can set =chinese-enable-avy-pinyin= to =nil=.

#+BEGIN_SRC emacs-lisp
  (setq-default dotspacemacs-configuration-layers '((chinese :variables
                                                             chinese-enable-avy-pinyin nil)))
#+END_SRC

* Key bindings
Currently, there are no built-in key bindings for this layer. You could define
your own preference.

Here are a few suggested key bindings (remember that ~SPC o~ is reserved for
personal usage, spacemacs won´t put any binding under this prefix):

** Youdao Dictionary
Bind ~SPC o y~ to =youdao-dictionary-search-at-point+=.

** Find-by-pinyin-dired
Bind ~SPC o d~ to =find-by-pinyin-dired=
