症状:Sublime text 3 for linux 无法使用搜狗拼音输入法

系统:Linux Mint 18.1

解决方案如下:

1. 保存下述代码为 sublime-imfix.c 文件

/*
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);
}

 

2. 安装 C/C++ 的编译环境和 gtk libgtk2.0-dev

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

 

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. 设置 LD_PRELOAD 并启动 Sublime Text

LD_PRELOAD=./libsublime-imfix.so subl

 

5. 修改 /usr/share/applications/sublime_text.desktop 为

[Desktop Entry]
[…]
Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text %F
[…]

[Desktop Action Window]
[…]
Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text -n
[…]

[Desktop Action Document]
[…]
Exec=env LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so /opt/sublime_text/sublime_text –command new_file
[…]

不要忘了把 libsublime-imfix.so 放到 /opt/sublime_text/ 中

 

6. 修改 /usr/bin/subl 为

#!/bin/sh

export LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so
exec /opt/sublime_text/sublime_text “$@”
