The packages in this repository define extensions to the standard Go “flag”
package for additional types beyond the standard set, by providing
implementations of the flag.Value and
flag.Getter interfaces.
Subpackages
sizeflag
Defines a flag that accepts human-readable integer values, with shorthand for
multiples of powers of 1024. For example, “1K” for 1024, “2.1m” for 2202009,
and so forth.
enumflag
Defines a flag that accepts a single string value taken from a fixed set of
values chosen when the flag is defined. Values are compared without regard to
case.
regexpflag
Defines a flag that accepts a valid
*regexp.Regexp
value compiled from a string literal.
timeflag
Defines a flag that accepts a time.Time
value parsed via a standard format string.
