Overview

Package flagtypes provides types that implement the pflags.Value interface for converting command line flags to objects.

Functions

func GLog

func GLog(flags *pflag.FlagSet)

GLog binds the log flags from the default Google "flag" package into a pflag.FlagSet.

Types

type Addr

type Addr struct {
	// Specified by the caller
	DefaultScheme string
	DefaultPort   int
	AllowPrefix   bool

	// Provided will be true if Set is invoked
	Provided bool
	// Value is the exact value provided on the flag
	Value string

	// URL represents the user input. The Host field is guaranteed
	// to be set if Provided is true
	URL *url.URL
	// Host is the hostname or IP portion of the user input
	Host string
	// IPv6Host is true if the hostname appears to be an IPv6 input
	IPv6Host bool
	// Port is the port portion of the user input. Will be 0 if no port was found
	// and no default port could be established.
	Port int
}

Addr is a flag type that attempts to load a host, IP, host:port, or URL value from a string argument. It tracks whether the value was set and allows the caller to provide defaults for the scheme and port.

func (Addr) Default

func (a Addr) Default() Addr

Default creates a new Address with the value set

func (*Addr) HostPort

func (a *Addr) HostPort(defaultPort int) string

HostPort returns the host and port joined together. If no port is set :0 will be appended.

func (*Addr) Set

func (a *Addr) Set(value string) error

Set attempts to set a string value to an address

func (*Addr) String

func (a *Addr) String() string

String returns the string representation of the Addr

func (*Addr) Type

func (a *Addr) Type() string

Type returns a string representation of what kind of value this is

type IP

type IP net.IP

IP adapts net.IP for use as a flag.

func (*IP) Set

func (ip *IP) Set(value string) error

func (IP) String

func (ip IP) String() string

func (*IP) Type

func (ip *IP) Type() string

Type returns a string representation of what kind of argument this is

type IPNet

type IPNet net.IPNet

IPNet adapts net.IPNet for use as a flag.

func DefaultIPNet

func DefaultIPNet(value string) IPNet

func (*IPNet) Set

func (ipnet *IPNet) Set(value string) error

func (IPNet) String

func (ipnet IPNet) String() string

func (*IPNet) Type

func (ipnet *IPNet) Type() string

Type returns a string representation of what kind of argument this is
