Ubuntu 下讓sublime-text3支持中文輸入法

http://bbs.chinahtml.com/t319624/

1.安裝谷歌拼音

sudo add-apt-repository ppa:fcitx-team/nightly
sudo apt-get update
sudo apt-get install fcitx fcitx-googlepinyin

2.把系統的輸入法改成fcitx
System Setting >>Language surpport >> Language >> Keyborad input method system >> fcitx

fictx開機自啓動：
System Setting >> Startup Applications >> Add

Name: Fcitx
Command: /usr/bin/fcitx -d
Comment:Fcitx startup

將下面代碼保存爲 sublime_imfix.c並保存在sublime安裝的目錄下
sublime_text3默認安裝的目錄：/opt/sublime_text/

安裝C/C++的編譯環境和gtk libgtk2.0-dev

sudo apt-get install build-essential  
sudo apt-get install libgtk2.0-dev

編譯成共享庫

gcc -shared -o libsublime-imfix.so sublime-imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC

啓動 Sublime Text 試一試，現在可以使用fcitx輸入中文了

LD_PRELOAD=./libsublime-imfix.so subl

但是這樣的話，我們每次都要在終端裏面使用命令啓動sublime text 2，這樣很不方便，接下來我們還要通過修改sublime-text-2.desktop達到點擊圖標啓動。

複製 libsublime-imfix.so 至 /usr/lib/

mv libsublime-imfix.so /usr/lib

打開終端進入applications修改sublime-text-2.desktop

cd /usr/share/applications
sudo vi sublime_text.desktop

打開sublime_text.desktop後，將
Exec=/opt/sublime_text/sublime_text %F
修改爲
Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /opt/sublime_text/sublime_text' %F

將
Exec=/opt/sublime_text/sublime_text -n
修改爲
Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /opt/sublime_text/sublime_text' -n
Ok如此即可，開始sublime無憂代碼之旅
