解决 Ubuntu 下 Sublime Text 无法输入中文的问题

1. 安装依赖库

sudo apt-get install build-essential

sudo apt-get install libgtk2.0-dev

2. 编译共享库

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

sublime_imfix.c内容如下：

/*

sublime-imfix.c

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

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

LD_PRELOAD=./libsublime-imfix.so subl

#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) {

    g_return_if_fail(region != NULL);

    g_return_if_fail(rectangle != NULL);

    rectangle->width = region->extents.x2 - region->extents.x1;

    GdkRectangle rect;

    rect.x = rectangle->x;

    rect.y = rectangle->y;

    rect.width = 0;

    rect.height = rectangle->height;

    //The caret width is 2;

    //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

//context will lost, so here we set it again.

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

    XEvent *xev = (XEvent*)xevent;

    if (xev->type == KeyRelease && GTK_IS_IM_CONTEXT(im_context)) {

        GdkWindow * win = g_object_get_data(G_OBJECT(im_context), "window");

        if (GDK_IS_WINDOW(win)) {

            gtk_im_context_set_client_window(im_context, win);

        }

    }

    g_return_if_fail(GTK_IS_IM_CONTEXT(context));

    klass = GTK_IM_CONTEXT_GET_CLASS(context);

    if (klass->set_client_window) {

        klass->set_client_window(context, window);

    }

    if (!GDK_IS_WINDOW(window)) {

        return;

    }

    g_object_set_data(G_OBJECT(context), "window", window);

    int width = gdk_window_get_width(window);

    int height = gdk_window_get_height(window);

    if (width != 0 && height != 0) {

        local_context = context;

    }

    gdk_window_add_filter(window, event_filter, context);

}

3. 移动共享库到Sublime Text 3安装目录

sudo mv libsublime-imfix.so /opt/sublime_text

4. 修改启动脚本

sudo vim /usr/bin/subl

subl内容如下：

#!/bin/sh

export LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so:$LD_PRELOAD

exec /opt/sublime_text/sublime_text "$@"

5. 修改/usr/share/appliations/sublime_text.desktop

sudo sed -i 's/\/opt\/sublime_text\/sublime_text/subl/g' /usr/share/applications/sublime_text.desktop

6. 替换本地的sublime_text.desktop

cp /usr/share/applications/sublime_text.desktop ~/.local/share/applications/sublime_text.desktop
