让sublime可以和visual studio一样自动在运算符前后添加空格的插件

用过vs的人都知道,vs会自动在代码中运算符的前后加空格,比如 i=1; 换行后会自动变成i = 1;
开始觉得这个挺烦的,后来习惯了,发现这个功能还是挺好的,然代码更清晰.
最近换了sublimetext3,也想有类似功能,找了好久,没有发现很满意的,于是就自己动手了
代码很简单
使用方法(仅限于sublimetext3, 2的话没试过):
在sublimetext3根目录的Data/Packages目录下见一个叫InsertSpace的目录
InsertSpace目录下建一个文件InsertSpace.py, 把InsertSpace的代码复制下来在粘贴到这个文件
然后复制键绑定的代码,粘贴到键绑定文件中
OK
注意:这个键绑定只在c,c++,py,cs文件中起作用,我是用来写c的,所以只做了c运算符
要在其他文件中起作用,修改键绑定代码中:
{ “key”: “selector”, ……
行,加入相应的文件scope名即可,其他代码文件运算符可能不一样,要做相应修改

按键绑定
