发表于   |  

sublime_text 被称为’神器’,自然有它的长处,但是在linux系统安装sublime_text 后,你会发现,无法输入中文,本文会解决 sublime_txt 无法输入中文的问题.

测试系统:Linux Mint 17.2
输入法:搜狗输入法
Sublime Text版本:Sublime Text 3 Build 3083

关于如何安装输入法和sublime,在这里不做叙述,自行百度.

  1. 保存下面的代码为sublime-imfix.c 文件

    #include <gtk/gtk.h>
    #include <gdk/gdkx.h>
    typedef GdkSegment GdkRegionBox;
    struct _GdkRegion
    {
      long size;
      long numRects;

    }

  2. 安装 C/C++ 的编译环境和 gtk libgtk2.0-dev

    1
    2
    sudo apt-get install build-essential
    sudo apt-get install libgtk2.0-dev

  3. 编译共享内库

    1
    gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC

  4. 设置 LD_PRELOAD 并启动 Sublime Text

    1
    LD_PRELOAD=./libsublime-imfix.so subl

  5. 修改 /usr/share/applications/sublime_text.desktop 为

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    13
    14
    15
    16
    17
    18
    19
    20
    21
    22
    23
    [Desktop Entry]
    Version=1.0
    Type=Application
    Name=Sublime Text
    GenericName=Text Editor
    Comment=Sophisticated text editor for code, markup and prose
    Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text %F
    Terminal=false
    MimeType=text/plain;
    Icon=sublime-text
    Categories=TextEditor;Development;
    StartupNotify=true
    Actions=Window;Document;
    [Desktop Action Window]
    Name=New Window
    Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text -n
    OnlyShowIn=Unity;
    [Desktop Action Document]
    Name=New File
    Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text --command new_file
    OnlyShowIn=Unity;

  6. 把 libsublime-imfix.so 移动到 /opt/sublime_text/ 中

    1
    mv libsublime-imfix.so /opt/sublime_text/

  7. 修改 /usr/bin/subl 为

    1
    2
    3
    4
    #!/bin/sh
    export LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so
    exec /opt/sublime_text/sublime_text "$@"

  8. 重启电脑

到此,就可以在sublime中输入中文,可以愉快的码字啦~
