class Athena::Console::Input::Argument
inherits Reference
#
Represents a value (or array of values) provided to a command as a ordered positional argument, that can either be required or optional, optionally with a default value and/or description.
Arguments are strings separated by spaces that come after the command name.
For example, ./console test arg1 "Arg2 with spaces".
Arguments can be added via the ACON::Command#argument method,
or by instantiating one manually as part of an ACON::Input::Definition.
The value of the argument could then be accessed via one of the ACON::Input::Interface#argument overloads.
See ACON::Input::Interface for more examples on how arguments/options are parsed, and how they can be accessed.
