PHP Class Webmozart\Console\Api\Args\Format\Argument
Args arguments are passed after the command name and its options. In the
example below, "localhost" is the argument to the "server -d" command.
$ console server -d localhost
Arguments can be either optional or required. By default, all arguments are
optional, but you can explicitly make an argument optional or required by
passing one of the flags {@link OPTIONAL} and {@link REQUIRED} to the
constructor:
php
$argument = new Argument('server', Argument::REQUIRED);
Arguments can also be multi-valued. Multi-valued arguments can be passed any
number of times:
$ console server -d localhost google.com
To create a multi-valued argument, pass the flag {@link MULTI_VALUED} to the
constructor:
php
$argument = new Argument('server', Argument::MULTI_VALUED);
You can combine the {@link MULTI_VALUED} flag with either {@link OPTIONAL}
or {@link REQUIRED} using the bitwise operator "|":
php
$argument = new Argument('server', Argument::REQUIRED | Argument::MULTI_VALUED);
