Mac 的自带输入法
中文很不友好，安装了Sougou 输入法之后，各种编辑器之间来回切换之后，状态很乱，当前明明切换成英文了 按键的时候却是中文，有时候明明是中文，输入又是英文，不断的切切切，几近崩溃…不断的切换，太烦人
自动切换输入法
找到一种办法，是保证在某些特定的几个应用里，始终默认是英文，其他的随便。这样每次回到那几个特定的编辑器时 最多切换一次，就保证满足需求
保险配置
最好再把下面这个选中 Mac - settings - keyboard - input source - Automatically switch to a document’s input source
创建Python文件，内容如下

AppHelper.runConsoleEventLoop(installInterrupt=True)
main()
然后配置开机启动
我是放到 ~/startup/ 目录下
这个目录忘了当时是怎么配置的，后面更新出来
当然也可以按照 blog 上说的，用supervisor配置/编写plist加入开机启动/或者账户中心添加自动启动项目
