Sublime Text 3配置以及中文输入问题

字体设置问题：

安装完Sublime后，由于Ubuntu下面没有MS下的字体Consolas，Sublime默认的字体为非等宽字体。于是设置Ubuntu文本编辑器gedit下的默认字体Ubuntu Mono作为Sublime的字体。

{
    "color_scheme": "Packages/Color Scheme - Default/Monokai.tmTheme",
    "font_face": "Ubuntu Mono",
    "font_size": 13,
    "translate_tabs_to_spaces": true
}

中文输入问题：

安装搜狗输入法后，依然不能够在Sublime下进行中文输入。Google参考了以下文章：

问题解决了。具体的设置上面链接已经说的非常明白，不再重述。

创建sublime-imfix.c代码如下：

/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang <jianzhong.huang at i-soft.com.cn>

gcc -shared -o libsublime-imfix.so sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC
LD_PRELOAD=./libsublime-imfix.so sublime_text
*/
#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); 
}

 接下来编译动态链接如下：

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

通过下列方式启动sublime即可实现中文输入了

LD_PRELOAD=./libsublime-imfix.so sublime_text

为了能够直接启动时也能够实现中文输入，还需要以下步骤：

将libsublime-imfix.so拷贝到sublime的安装目录/opt/sublime_text下。

cp libsublime-imfix.so /opt/sublime_text 

修改/usr/share/applications/sublime_text.desktop

分别将

Exec=/opt/sublime_text/sublime_text %F
Exec=/opt/sublime_text/sublime_text -n
Exec=/opt/sublime_text/sublime_text --command new_file

改为

Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text %F'
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text -n'
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text --command new_file'

所有步骤完成，打开sublime就可以输入中文了。
