sublime是一款非常令人爱不释手的编译器,功能强大,界面美观,跨平台。但是最近在ubuntu下发现他没法输入中文,本来写代码可能需要的中文输入情况比较少,但是奈何有时候写写markdown,注释之类的可能还是需要用到中文,所以今天索性找方法解决他。
这种问题力求快速解决,不废话.

安装搜狗输入法

搜狗输入法最近适配了linux系统,简直是linux粉们的福音,安装可以参见Sougoupinyin官网,安装完成后,需要进行重启并且配置输入法(按win键,然后输入keyboard),选择Fcitx.

安装补丁

装完搜狗貌似还是不能进行中文输入,网上找到一个解决方案:

新建文件sub-fcitx.c,建议放到Subime Text所在的目录下,将下面的代码复制:

/*

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

#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);
}

安装变异环境

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

切换到sub-fcitx.c,所在目录,编译生成so文件.
正常的话,目录下会多一个libsublime-imfix.so文件

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

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。

添加启动脚本

~/bin目录下新建文件sub3,把下面的的代码复制到文件里,其中SUB3_HOME是Sublime Text的根目录,根据自己放的目录更改。另外,Ubuntu13.04下~/bin是默认在用户PATH里的,其它系统可能要自己在~/.bash_profile或者~/.profile中添加环境变量。

#!/bin/bash
SUB3_HOME=$HOME/Software/sublime_text_3
CMD="LD_PRELOAD=./libsublime-imfix.so ./sublime_text"
FILENAME=$1
if [ -n "$1" ]
then 
 CMD=${CMD}" "`pwd`/$FILENAME
fi
cd "$SUB3_HOME"
eval $CMD   

修改文件权限

chmod 777 sub3

测试,可以带参数表示文件名也可以不带参数

#打开Sublime Text,对文件a.sh进行编辑
sub3 a.sh
#打开Sublime Text,回到之前关闭时的工作状态
sub3
