Ubuntu下Sublime+Text+3無法輸入中文的解決方案(2016

測試系統：Ubuntu 14.04（理論上所有 Linux 發行版都通用）

輸入法：sohu input method for linux

Sublime Text 版本：Sublime Text 3

×1. 保存下述代碼為 sublime-imfix.c 文件

[code]/*
sublime-imfix.c
Use LD_PRELOAD to interpose some function to fix sublime input method support for linux.

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

#include <gtk/gtk.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. 安裝 C/C++ 的編譯環境和 gtk libgtk2.0-dev

sudo apt-get install build-essential

sudo apt-get install libgtk2.0-dev

×3.

gcc -shared -o libsublime-imfix.so sublime-imfix.c

pkg-config --libs --cflags gtk+-2.0

-fPIC *4.將subl移動到/usr/bin/，並且將sublime-imfix.so移動到/opt/sublime_text/（sublime的安裝目錄）

終端輸入：

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

×5. 設置 LD_PRELOAD 並啟動 Sublime Text

LD_PRELOAD=./libsublime-imfix.so subl

*6.但是這樣子只能用上述命令行啟動才能輸入中文，我們需要更簡單的辦法，我選擇新建一個shell腳本，很簡單，就一句話。

sublime新建文件輸入：

[code]#!/bin/bash
LD_PRELOAD=/opt/sublime_text/libsublime-imfix.so subl

然後將文件另存為sublime（注意：沒有後綴），並且放到/home文件夾。

至此，所有工作完成了。想要啟動，直接終端輸入：bash ~/sublime，就可以啟動sublime，並且能夠輸入中文。

如果不需要輸入中文，直接按以前的方式打開即可。建腳本文件的目的就是方便打開能輸入中文的sublime。

*7.

網上其它腳本方案：

修改 /usr/share/applications/sublime_text.desktop 為

[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

修改 /usr/bin/subl 為

[code]#!/bin/sh

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