虽然ST大多数时候都是拿来Coding,很少会写汉子。但是我自己比较喜欢写一下杂的东西,这样没有汉子输入是很难受啊。

解决ST在linux的中文输入问题目前应该就两种方法,一种是安装ST的input插件但是每次都要调出感觉很烦,另一种就是编译共享内库。我自己用的是搜狗拼音输入法,其他输入法未测试,系统是Fedora 20 64位。网上大部分教程都是Ubuntu的,这里只是简单的修改了一下,没有多大的变动。


1、保存以下代码到sublime-imfix.c

/*
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); 
}

2、安装gtk开发包

# yum install gtk2.0-devel 注意:我电脑上是安装有gcc等编译工具的,如果你没有请自行安装gcc等

3、编译共享内库

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

4、测试一下

LD_PRELOAD=./libsublime-imfix.so st 注意:后面的st是我启动st的命令,你应该换成自己的

5、修改一下

每次都要这样启动的确很烦,我们修改一下。

编辑/usr/bin/st 文件

#!/bin/sh
exec /opt/sublime_text_2/sublime_text "$@"

将其修改成

#!/bin/sh
LD_PRELOAD=/usr/lib/libsublime-imfix.so exec /opt/sublime_text_2/sublime_text "$@"

这样我们每次启动就可以直接输入汉字了。

我在桌面页放了快捷方式那就要将快捷方式也修改一下

编辑/usr/share/applications/sublime-text-2.desktop

[Desktop Entry]
Name=Sublime Text 2  
GenericName=Text Editor  
Icon=sublime_text  
Comment=Sophisticated text editor \for code, markup and prose  
Exec=st %F  
MimeType=text/plain;  
Terminal=false  
Type=Application  
StartupNotify=true  
Categories=Development;Utility;TextEditor;  
Keywords=Text;Editor;

然后将/usr/share/applications/sublime-text-2.desktop复制到~/Desktop

# cp /usr/share/applications/sublime-text-2.desktop ~/Desktop
就是将Exec命令后面的改成我们修改的/usr/bin/st,如上所示。这样每次从桌面启动,也可以直接输入汉字。
