Types

type RegexpSlice

type RegexpSlice []*regexp.Regexp

RegexpSlice is a flag value that parses one or more regular expressions.

All regular expressions parsed by this type will be case-insensitive.

func (*RegexpSlice) Set

func (s *RegexpSlice) Set(value string) error

Set compiles value and adds it to s. The regular expression will be case-insensitive.

If the regular expression cannot be compiled an error will be returned.

func (*RegexpSlice) String

func (s *RegexpSlice) String() string

String returns a string representation of the regular expression slice.

type UintOrInf

type UintOrInf struct {
	Present bool
	Inf     bool
	Value   uint
}

UintOrInf stores an unsigned integer value that can be used by the flag package. It is capable of indicating the special value infinity and whether a value was specified or not.

func (*UintOrInf) Set

func (u *UintOrInf) Set(value string) (err error)

Set parses the given value and assigns it to u.

If value cannot be parsed an error will be returned.

func (*UintOrInf) String

func (u *UintOrInf) String() string

String returns a string representation of the unsigned integer.
