command can accept either a string or an array. Represents the command to dispatch
extra can accept an array of extra parameters to pass on to the dispatcher. This parameters will be available in the param property of the called Shell

Method on the shell.
Matching task name.
main() method.

If a shell implements a main() method, all missing method calls will be sent to main() with the original method name in the argv.

For tasks to be invoked they must be exposed as subcommands. If you define any subcommands, you must define all the subcommands your shell needs, whether they be methods on this class or methods on tasks.

Parameters

array $argv

Array of arguments to run the shell with. This array should be missing the shell name.

bool $autoMethod optional

Set to true to allow any public method to be called even if it was not defined as a subcommand. This is used by ShellDispatcher to make building simple shells easy.

array $extra optional

Extra parameters that you can manually pass to the Shell to be dispatched. Built-in extra parameter is :

requested : if used, will prevent the Shell welcome message to be displayed

Returns

int|bool|null
