Command line arguments can be separated into options and positional parameters.
|
|
Following sections describes features how options are defined and used. We first
|
|
go through some basics about using options and then go into details about
|
|
various ways how options and arguments works.
|
|
|
|
Generally speaking an _option_ is something after a commands prefixed with
|
|
either `-` or `--`. An _option_ can either have a value or not depending
|
|
on its context.
|
|
|
|
Options can be defined with a target method using annotations with a method
|
|
arguments or with programmatically using `CommandRegistration`.
|
|
|
|
NOTE: In below sections `@ShellOption` refer to a _legacy annotation model_
|
|
and `@Option` refer to an _annotation model_.
