Linux 下 Sublime Text 中文输入问题的解决方案

1.保存下面的代码为sublime_imfix.c

复制代码

代码如下:

/*
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.编译动态库：

复制代码

代码如下:

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

3. 设置 ld_preload 并启动 sublime text：

复制代码

代码如下:

ld_preload=./libsublime-imfix.so sublime_text

为了不用每次启动sublime text都打这么一长串东西，写了个启动sublime的脚本：

复制代码

代码如下:

#!/bin/bash

sublime_home="/opt/sublime_text"
ld_lib=$sublime_home/libsublime-imfix.so
sh -c "ld_preload=$ld_lib $sublime_home/sublime_text $@"

把libsublime-imfix.so放到sublime text目录下并修改脚本中的sublime_home，这样sublime text 就可以输入中文啦，谢谢阅读，希望能帮到大家，请继续关注，我们会努力分享更多优秀的文章。
