How to switch to fcitx input method in Ubuntu Sublime Text 2

Sublime Text 2 is a code editor. If you want to input Chinese, you need to use the fcitx input method. Recently, some netizens have encountered the situation that Sublime Text 2 cannot use the fcitx input method. The following small series will introduce you to Ubuntu. Sublime Text 2 cannot switch the solution to the fcitx input method.

Save to save this following code ~ /sublime-imfix.c

/*

sublime-imfix.c

Use LD_PRELOAD To interpose some function to fix sublime input method support for linux.

Install C/C++ build environment and gtk libgtk2.0-dev

sudo apt-get install build-essential

sudo apt-get install libgtk2.0-dev

Use the terminal to enter the sublime-imfix.c directory, run the following command

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

Modify /usr/share/with a text editor Applications/sublime.desktop file (this is what you built when you installed sublime text 2), found at the beginning of & Ldquo;Exec=” lines (with two lines), modify subl to

bash -c ‘LD_PRELOAD=~/libsublime-imfix.so subl’

OK, at startup Click on sublime text 2 to enter Chinese! (Note: The Chinese input method cannot be switched when the terminal input subl is turned on.)

The above is the introduction of the Ubuntu Sublime Text 2 solution that cannot use the fcitx input method. After modifying the subl according to the method described in this article, The launcher launches Sublime Text 2.
