Types

type Config 

type Config struct {
	Hosts             HostsMap `yaml:"hosts,omitempty,flow" json:"hosts"`
	Templates         HostsMap `yaml:"templates,omitempty,flow" json:"templates"`

	ASSHBinaryPath    string   `yaml:"asshbinarypath,omitempty,flow" json:"asshbinarypath,omitempty"`
	// contains filtered or unexported fields
}

Config contains a list of Hosts sections and a Defaults section representing a configuration file

func New 

func New() *Config

New returns an instantiated Config object

func Open 

func Open(path string) (*Config, error)

Open parses a configuration file and returns a *Config object

func (*Config) DisableAutomaticRewrite 

func (c *Config) DisableAutomaticRewrite()

DisableAutomaticRewrite will configure the ~/.ssh/config file to not automatically rewrite the configuration file

func (*Config) GetGatewaySafe 

func (c *Config) GetGatewaySafe(name string) *Host
