toggle system proxy by hammerspoon shortcuts in macos

1. set the ip and port of http and https proxy manually for the first time, which can be accomplished in command line though.
networksetup -setwebproxy "Wi-fi" 127.0.0.1 8080
networksetup -setsecurewebproxy "Wi-fi" 127.0.0.1 8080

2. add the following shell function to your ~/.profile
toggleProxy() {
	e=$(networksetup -getwebproxy wi-fi | grep "No")

	ns=wi-fi
	status=''
	if [ -n "$e" ]; then
	  status=on
	else
	  status=off
	fi

	echo -n "Turning $status proxy"
	networksetup -setstreamingproxystate $ns $status
	networksetup -setsocksfirewallproxystate $ns $status
	networksetup -setwebproxystate $ns $status
	networksetup -setsecurewebproxystate  $ns $status
}


3. add the following to your ~/.hammerspoon/init.lua
hs.hotkey.bind({"cmd", "alt", "ctrl"}, "P", function()
  local output = hs.execute("toggleProxy", true)
  hs.alert.show(output)
end)
