UBUNTU 14.04 安装fcitx-sougoupinyin, sublime text 3, 解决中文输入

适用于新安装的系统，要是做了很多操作，那就不好说了

换成163的源，更新，
language support里添加中文，界面语言是不必设为中文的
到http://pinyin.sogou.com/linux/?r=pinyin下载deb包安装
language support里输入方式选为fcitx
重启，sougoupinyin 安装成功

安装sublime text 3

sudo add-apt-repository ppa:webupd8team/sublime-text-3
sudo apt-get update
sudo apt-get install sublime-text-installer

解决中文输入问题

cd /opt/sublime_text
sudo touch sublime_imfix.c
sudo gedit sublime_imfix.c

然后把以下内容粘贴进去并且保存

#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); 
}

再执行：

sudo apt-get install build-essential libgtk2.0-dev
sudo gcc -shared -o libsublime-imfix.so sublime_imfix.c  `pkg-config --libs --cflags gtk+-2.0` -fPIC

再编辑sublime快捷方式

sudo gedit /usr/share/applications/sublime-text.desktop

把以下内容替换原来内容并且保存

[Desktop Entry]
Version=1.0
Type=Application
Name=Sublime Text
GenericName=Text Editor
Comment=Sophisticated text editor for code, markup and prose
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text' %F
Terminal=false
MimeType=text/plain;

[Desktop Action Window]
Name=New Window
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text' -n

Name=New File
Exec=bash -c 'LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text' --command new_file

完工。

可选，使用我的sublime配置文件

务必至少打开一次sublime text 3, 并且在关闭状态下执行以下操作

cd ~/.config/sublime-text-3
rm -rf Installed\ Packages
rm Packages/User/Package\ Control.sublime-settings
rm Packages/User/Preferences.sublime-settings
git clone https://github.com/zxdong262/sublime3-setting.git
cp -R sublime3-setting/* .
