Sublime Text 3 in Linux

Posted on Edited on In Disqus:

以下文章參考下列四個網址：

  1. 完美解决 Linux 下 Sublime Text 中文输入
  2. How do I make Sublime Text 3 the default text editor

linux上，中文輸入法一直是難題，應用程式沒辦法支援中文輸入是非常常見的事情，連sublime text也是。還不只如此，還有輸入法的戰爭，我在進入linux時，最一開使用的輸入法是gcin，然後去用hime，最後因為sublime text的解決方法只能只用fcitx，最後用了這個輸入法。

我看了不少文章提供各種sublime text輸入的問題，我覺得下列方法是最方便的：

  1. 把下列的程式碼存為sublime_imfix.c:

  1. Ctrl+Alt+T打開你的Terminal視窗到你儲存上面檔案的地方，鍵入：
1
2
3
sudo apt-get install build-essential libgtk2.0-dev
gcc -shared -o libsublime-imfix.so sublime-imfix.c `pkg-config --libs --cflags gtk+-2.0` -fPIC
sudo mv libsublime-imfix.so /opt/sublime_text/

這樣就完成編譯，並且將檔案放置到安裝目錄了。

  1. 修改啟動部份
1
sudo subl /usr/share/applications/sublime-text.desktop

在每一個Exec=後面都加上下面的指令：

1
env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so

然後輸入

1
sudo subl /usr/bin/subl

更動內容為

1
2
3
#!/bin/sh
export LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so
exec /opt/sublime_text/sublime_text "$@"
  1. 如果想要把sublime text更動為預設編輯器，先使用下列指令確定是否有安裝成功：
1
ls /usr/share/applications/sublime-text.desktop

接著打開linux的default列表：

1
sudo subl /usr/share/applications/defaults.list

按下Ctrl+H replace gedit with sublime-text。接著打開user的設定列表：

1
subl ~/.local/share/applications/mimeapps.list

修改或添加下列下列文字：
