Parameters

Definition Syntax

Positional

Mandatory part: positional-name
Optional parts:

• value type: name:type-name. Defaults to string
• collective tag: name... or typed variant name:type-name...
• optional tag: [name]

All the optional parts can be combined.
Examples: count:int, [optional-names...]

Note. The collective tag results into array of parameter type instances. e.g. name... -> string[], digits:int... -> int[].

Switch

--switch-name - as simple as that, e.g. --verbose, --debug, --dry-run.

Option

Just a switch, followed by a positional, and optional default value after =,
e.g. --option param:type...=default, --option [param...].
If default value omitted, it's set to null.
