Types

type ComponentFlag

type ComponentFlag struct {
	// contains filtered or unexported fields
}

ComponentFlag represents a set of enabled components used in a command line.

func NewComponentFlag

func NewComponentFlag(mappings map[string][]string, allowed ...string) *ComponentFlag

NewComponentFlag returns a flag that represents the allowed components and can be bound to command line flags.

func (*ComponentFlag) Allowed

func (f *ComponentFlag) Allowed() sets.String

Allowed returns a copy of the allowed list of components.

func (*ComponentFlag) Bind

func (f *ComponentFlag) Bind(flags *pflag.FlagSet, flagFormat, messagePrefix string)

Bind registers the necessary flags with a flag set.

func (*ComponentFlag) Calculated

func (f *ComponentFlag) Calculated() sets.String

Calculated returns the effective enabled list.

func (*ComponentFlag) DefaultDisable

func (f *ComponentFlag) DefaultDisable(components ...string) *ComponentFlag

DefaultDisable resets the default enabled set to all allowed components except the provided.

func (*ComponentFlag) DefaultEnable

func (f *ComponentFlag) DefaultEnable(components ...string) *ComponentFlag

DefaultEnable resets the enabled components to only those provided that are also in the allowed list.

func (*ComponentFlag) Disable

func (f *ComponentFlag) Disable(components ...string)

Disable marks the provided components as disabled.

func (*ComponentFlag) Enabled

func (f *ComponentFlag) Enabled(name string) bool

Enabled returns true if the component is enabled.

func (*ComponentFlag) Expand

func (f *ComponentFlag) Expand(value string) sets.String

Expand turns a string into a fully expanded set of components, resolving any mappings.

func (*ComponentFlag) Mappings

func (f *ComponentFlag) Mappings() map[string][]string

Mappings returns a copy of the mapping list for short names.

func (*ComponentFlag) Validate
