解决Ubuntu下使用命令行subl 打开Sublime text3无法输入中文的问题

 cd /opt/sublime_text/
 sudo vim sub-fcitx.c

   新建文件sub-fcitx.c，建议放在Sublime Text的所在目录下，将下面的代码复制进去 ，参考： http://jianghang.name/index.php/archives/11/

#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->x = region->extents.x1;
    rectangle->y = region->extents.y1;
    rectangle->width = region->extents.x2 - region->extents.x1;
    rectangle->height = region->extents.y2 - region->extents.y1;
    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);
        }
    }

    return GDK_FILTER_CONTINUE;
}

void gtk_im_context_set_client_window (GtkIMContext *context,
                                       GdkWindow    *window)
{
    GtkIMContextClass *klass;
    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) {
        gtk_im_context_focus_in(context);
        local_context = context;
    }

    gdk_window_add_filter (window, event_filter, context);
}

2.安装编译环境

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

3.切换到sub-fcitx.c，所在目录，编译生成so文件

1. cd /opt/sublime_text/
   sudo gcc -shared -o libsublime-imfix.so sub-fcitx.c `pkg-config --libs --cflags gtk+-2.0` -fPIC

正常的话，目录下会多一个libsublime-imfix.so文件
切换到Sublime Text目录下，通过LD_PRELOAD=./libsublime-imfix.so ./sublime_text命令启动Sublime Text之后，就会发现可以输入中文了，但是这样太麻烦了，通过添加自己的启动脚本可以简化这一过程

4. 修改在终端通过 subl 直接启动sublime的命令。

1. sudo vim /usr/bin/subl

    在第一行添加，图标的网上有很多，不赘述。

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