// Package arg parses command line arguments using the fields from a struct.
|
||
|
|
//
|
||
|
|
// For example,
|
||
|
|
//
|
||
|
|
// var args struct {
|
||
|
|
// Iter int
|
||
|
|
// Debug bool
|
||
|
|
// }
|
||
|
|
// arg.MustParse(&args)
|
||
|
|
//
|
||
|
|
// defines two command line arguments, which can be set using any of
|
||
|
|
//
|
||
|
|
// ./example --iter=1 --debug // debug is a boolean flag so its value is set to true
|
||
|
|
// ./example -iter 1 // debug defaults to its zero value (false)
|
||
|
|
// ./example --debug=true // iter defaults to its zero value (zero)
|
||
|
|
//
|
||
|
|
// The fastest way to see how to use go-arg is to read the examples below.
|
||
|
|
//
|
||
|
|
// Fields can be bool, string, any float type, or any signed or unsigned integer type.
|
||
|
|
// They can also be slices of any of the above, or slices of pointers to any of the above.
|
||
|
|
//
|
||
|
|
// Tags can be specified using the `arg` package name:
|
||
|
|
//
|
||
|
|
// var args struct {
|
||
|
|
// Input string `arg:"positional"`
|
||
|
|
// Log string `arg:"positional,required"`
|
||
|
|
// Debug bool `arg:"-d,help:turn on debug mode"`
|
||
|
|
// RealMode bool `arg:"--real"
|
||
|
|
// Wr io.Writer `arg:"-"`
|
||
|
|
// }
|
||
|
|
//
|
||
|
|
// The valid tag strings are `positional`, `required`, and `help`. Further, any tag string
|
||
|
|
// that starts with a single hyphen is the short form for an argument (e.g. `./example -d`),
|
||
|
|
// and any tag string that starts with two hyphens is the long form for the argument
|
||
|
|
// (instead of the field name). Fields can be excluded from processing with `arg:"-"`.
