fedora27 sublime3 fcitx 中文输入 解决

1：cat /proc/version

yangbh@corp software ->  
$ cat /proc/version
Linux version 4.13.13-300.fc27.x86_64 ([email protected]) (gcc version 7.2.1 20170915
(Red Hat 7.2.1-2) (GCC)) #1 SMP Wed Nov 15 15:47:50 UTC 2017

2:安装sublime3

        2.1  Install the GPG key:

sudo rpm -v --import https://download.sublimetext.com/sublimehq-rpm-pub.gpg

        2.2  use Stable

sudo dnf config-manager --add-repo https://download.sublimetext.com/rpm/stable/x86_64/sublime-text.repo

2.3  Update dnf and install Sublime Text

sudo dnf install sublime-text

安装完成后在/opt/sublime_text目录下

3:编译sublime-imfix共享库

3.1 新建 sublime-imfix.c 文件，内容如下

/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.
By Cjacker Huang

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

3.2   安装依赖

sudo dnf install gcc gtk2-devel.x86_64

3.3  编译共享库，生成libsublime-imfix.so文件

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

4:  复制文件到 /opt/sublime_text 目录下

sudo cp libsublime-imfix.so /opt/sublime_text/

5:新建命令 /usr/local/bin/sublime3

vi /usr/local/bin/sublime3 输入内容如下：

#!/bin/bash
LD_PRELOAD=/usr/local/sublime_text_3/libsublime-imfix.so /usr/local/sublime_text_3/sublime_text

添加执行权限

chmod +x /usr/local/bin/sublime3

此时可以从终端运行sublime3,已经可以输入中文了

6: 快捷方式修改

vi /usr/share/applications/sublime_text.desktop

yangbh@corp sublime_text ->  
$ cat /usr/share/applications/sublime_text.desktop  

[Desktop Entry]
Version=1.0
Type=Application
Name=Sublime Text
GenericName=Text Editor
Comment=Sophisticated text editor for code, markup and prose
#Exec=/opt/sublime_text/sublime_text %F
Exec=sublime3 %F
Terminal=false
MimeType=text/plain;
Icon=sublime-text
Categories=TextEditor;Development;
StartupNotify=true
Actions=Window;Document;

[Desktop Action Window]
Name=New Window
#Exec=/opt/sublime_text/sublime_text -n
Exec=sublime3
OnlyShowIn=Unity;

[Desktop Action Document]
Name=New File
Exec=sublime3 --command new_file
#Exec=/opt/sublime_text/sublime_text --command new_file
OnlyShowIn=Unity;

此时，通过快捷方式进入的sublime3，也可以输入中文啦。。。。。
