用過vs的人都知道,vs會自動在代碼中運算符的前后加空格,比如 i=1; 換行后會自動變成i = 1;
開始覺得這個挺煩的,后來習(xí)慣了,發(fā)現(xiàn)這個功能還是挺好的,然代碼更清晰.
最近換了sublimetext3,也想有類似功能,找了好久,沒有發(fā)現(xiàn)很滿意的,于是就自己動手了
代碼很簡單
使用方法(僅限于sublimetext3, 2的話沒試過):
在sublimetext3根目錄的Data/Packages目錄下見一個叫InsertSpace的目錄
InsertSpace目錄下建一個文件InsertSpace.py, 把InsertSpace的代碼復(fù)制下來在粘貼到這個文件
然后復(fù)制鍵綁定的代碼,粘貼到鍵綁定文件中
OK
注意:這個鍵綁定只在c,c++,py,cs文件中起作用,我是用來寫c的,所以只做了c運算符
要在其他文件中起作用,修改鍵綁定代碼中:
{ "key": "selector", ......
行,加入相應(yīng)的文件scope名即可,其他代碼文件運算符可能不一樣,要做相應(yīng)修改
