Functions

func ForceCountry 

func ForceCountry(countryCode string)

ForceCountry forces config fetches to pretend client is running in the given countryCode (e.g. 'cn')

func Init 

func Init(
	configDir string, flags map[string]interface{}, userConfig common.UserConfig,
	proxiesDispatch func(interface{}, Source), onProxiesSaveError func(error),
	origGlobalDispatch func(interface{}, Source), onGlobalSaveError func(error),
	rt http.RoundTripper) (stop func())

Init determines the URLs at which to fetch proxy and global config and passes those to InitWithURLs, which initializes the config setup for both fetching per-user proxies as well as the global config. It returns a function that can be used to stop the reading of configs.
