Ubuntu系統下Sublime Text 2中fcitx中文輸入法的解決方法

Ubuntu系統下Sublime Text 2中fcitx中文輸入法的解決方法

前幾天把Ubuntu升級到了13.04 beta 2，順便安裝了fcitx 搜狗輸入法，可是發如今sublime text 2中沒法輸入中文，以前在ubuntu 12.04.2中fcitx正常輸入的，只是有一些小問題。

本着發現問題，解決問題的原則，咱就找解決方法唄，通過Google和論壇發帖，找到了解決方法。

在這裏感謝oschina的@Khiyuan 和 bruce.oy 這兩位朋友耐心的爲我解決問題。接下來咱就把方法寫出來。

1. 保存下述代碼爲 sublime-imfix.c 文件

   09	#include <gtk/gtk.h>

   10	#include <gdk/gdkx.h>

   11	typedef GdkSegment GdkRegionBox;

   12

   13	struct _GdkRegion

   14

   {

   15	long size;

   16	long numRects;

   17	GdkRegionBox *rects;

   18	GdkRegionBox extents;

   19

   };

   21	GtkIMContext *local_context;

   void

   24	gdk_region_get_clipbox (const GdkRegion *region,

   25	GdkRectangle    *rectangle)

   26

   {

   27	g_return_if_fail (region != NULL);

   28	g_return_if_fail (rectangle != NULL);

   29

   30	rectangle->x = region->extents.x1;

   31	rectangle->y = region->extents.y1;

   32	rectangle->width = region->extents.x2 - region->extents.x1;

   33	rectangle->height = region->extents.y2 - region->extents.y1;

   34	GdkRectangle rect;

   35	rect.x = rectangle->x;

   36	rect.y = rectangle->y;

   37	rect.width = 0;

   38	rect.height = rectangle->height;

   39	//The caret width is 2;

   40	//Maybe sometimes we will make a mistake, but for most of the time, it should be the caret.

   41	if(rectangle->width == 2 && GTK_IS_IM_CONTEXT(local_context)) {

   42	gtk_im_context_set_cursor_location(local_context, rectangle);

   43

   }

   44

   }

   45

   46	//this is needed, for example, if you input something in file dialog and return back the edit area

   47	//context will lost, so here we set it again.

   }

2. 安裝C/C++的編譯環境和gtk libgtk2.0-dev

   1	sudo apt-get install build-essential

   2	sudo apt-get install libgtk2.0-dev

   
   

3. 編譯共享內庫

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

   
   

4. 啓動 Sublime Text 2

   好了，如今執行下述命令啓動 Sublime Text 2，就能夠使用fcitx輸入中文了！

   1	LD_PRELOAD=./libsublime-imfix.so sublime_text

   
   

可是這樣的話，咱們每次都要在終端裏面使用命令啓動sublime text 2，這樣很不方便，接下來咱們還要經過修改sublime-text-2.desktop達到點擊圖標啓動。

打開終端進入applications修改sublime-text-2.desktop

1	cd /usr/share/applications

2	sudo vim sublime-text-2.desktop

打開sublime-text-2.desktop後，將

1	Exec=/usr/bin/sublime-text-2 %F

修改成

1	Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /usr/bin/sublime-text-2' %F

還有將

1	Exec=/usr/bin/sublime-text-2 --new-window

修改成

view sourceprint?

1	Exec=bash -c 'LD_PRELOAD=/usr/lib/libsublime-imfix.so /usr/bin/sublime-text-2' --new-window

好了，接下來你在dash中點擊打開sublime text2吧，開始你的代碼之旅吧。
