To override the default we therefore set environment variable TMPDIR on Unix systems, and both TMP and TEMP on Windows (they are almost exclusively aliases for the same path, and programs may refer to to either of them). This should make all libraries and forked processes use the same.

}

Remote defines a remote with a name, type, source and description

func GetRemotes 

func GetRemotes() []Remote

	// GetSectionList returns a slice of strings with names for all the
	// sections
	GetSectionList() []string

	// HasSection returns true if section exists in the config file
	HasSection(section string) bool

	// DeleteSection removes the named section and all config from the
	// config file
	DeleteSection(section string)

	// GetKeyList returns the keys in this section

func Data 

func Data() Storage

Data returns current config file storage

func LoadedData

LoadedData ensures the config file storage is loaded and returns it

type UpdateRemoteOpt 

type UpdateRemoteOpt struct {
	// Treat all passwords as plain that need obscuring
	Obscure bool `json:"obscure"`
	// Treat all passwords as obscured
	NoObscure bool `json:"noObscure"`
	// Don't interact with the user - return questions
	NonInteractive bool `json:"nonInteractive"`

	Continue bool `json:"continue"`
	// If set then ask all the questions, not just the post config questions
