Perfect solution for Linux under Sublime Text Chinese input

First of all, I refer to several articles, are pretty good, first listed:

1. Sublime-text-imfix: First of all, this method is the simplest, but there are some problems on my system. This can be highly recommended with this
2. The perfect solution for Linux under Sublime Text Chinese input: Speak more clearly, can also be used for reference.
3. Ubuntu under Sublime Text 3 to resolve the inability to input Chinese method: The most clear explanation, suggest to see.

Test system: Ubuntu 14.04 (theoretically all Linux distributions are generic)

Input Method: Fcitx 4.2.6.1

Sublime text version: Sublime text 3 dev (Build 3083) Green Edition

1. Save the following code as asublime-imfix.cfile

#include <gtk/gtk.h>
#include <gdk/gdkx.h>
typedef GdkSegment GdkRegionBox;
 
struct _GdkRegion
{
  long size;
  long numRects;
  GdkRegionBox *rects;
  GdkRegionBox extents;
};
 
GtkIMContext *local_context;
 
void
gdk_region_get_clipbox (const GdkRegion *region,
            GdkRectangle    *rectangle)

  //Maybe sometimes we will make a mistake, but for most of the time, it should be the caret.
  if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) {
        gtk_im_context_set_cursor_location(local_context, rectangle);
  }
}
 
//this is needed, for example, if you input something in file dialog and return back the edit area

static GdkFilterReturn event_filter (GdkXEvent *xevent, GdkEvent *event, gpointer im_context)

       if(GDK_IS_WINDOW(win))

}

2. Install the C + + compiler environment and GTK Libgtk2.0-dev (if installed, you can skip directly)

Shell

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

3. Compiling a shared internal library

Shell

1	Gcc -Shared -o libsublime-imfix.so sublime-imfix.c pkg-config --libs --cflags gtk+-2.0 ' -fpic

4. Set ld_preload and start Sublime Text

Shell

1	Ld_preload=. /libsublime-imfix. So subl

If you start successfully, you should be able to enter Chinese.

5. Change/usr/share/applications/sublime_text.desktopto

 
[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_3/libsublime-imfix.so /opt/sublime_text_3/sublime_text %F
Terminal=false
MimeType=text/plain;
Icon=/opt/sublime_text_3/sublime_text
Categories=TextEditor;Development;
StartupNotify=true
Actions=Window;Document;

[Desktop Action Window]
Name=New Window
Exec=env LD_PRELOAD=/opt/sublime_text_3/libsublime-imfix.so /opt/sublime_text_3/sublime_text -n
OnlyShowIn=Unity;

[Desktop Action Document]
Name=New File
Exec=env LD_PRELOAD=/opt/sublime_text_3/libsublime-imfix.so /opt/sublime_text_3/sublime_text --command new_file
OnlyShowIn=Unity;

Don't forget to put it libsublime-imfix.so/opt/sublime_text/in the middle

6. Change/usr/bin/sublto

Shell

#!/bin/sh
Export ld_preload=/opt/sublime_text_3/libsublime-imfix.so
Exec/opt/sublime_text_3/sublime_text "[Email protected]"
