在init的 lua脚本中，下面的代码是为了在进入Terminal、ShortCat和Spolight的时候，默认切换到英文输入法
local function Chinese()
hs.console.printStyledtext("chinese")
hs.keycodes.currentSourceID("com.apple.inputmethod.SCIM.ITABC")
end
local function English()
hs.console.printStyledtext(hs.keycodes.currentSourceID())
hs.keycodes.currentSourceID("com.apple.keylayout.ABC")
end
local function set_app_input_method(app_name, set_input_method_function, event)
event = event or hs.window.filter.windowFocused
hs.window.filter.new(app_name)
:subscribe(event, function() set_input_method_function() end)
end
set_app_input_method('Hammerspoon', English, hs.window.filter.windowCreated)
set_app_input_method('Spotlight', English, hs.window.filter.windowCreated)
set_app_input_method('Shortcat', English, hs.window.filter.windowCreated)
set_app_input_method('Terminal', English)
