dispatchShell()source public

dispatchShell( )

Dispatch a command to another Shell. Similar to Object::requestAction() but intended for running shells from other shells.

Usage:

With a string command:

return $this->dispatchShell('schema create DbAcl');

Avoid using this form if you have string arguments, with spaces in them. The dispatched will be invoked incorrectly. Only use this form for simple command dispatching.

With an array command:

return $this->dispatchShell('schema', 'create', 'i18n', '--dry');

With an array having two key / value pairs: - 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

return $this->dispatchShell([ 'command' => 'schema create DbAcl', 'extra' => ['param' => 'value'] ]);

or

return $this->dispatchShell([ 'command' => ['schema', 'create', 'DbAcl'], 'extra' => ['param' => 'value'] ]);

Returns

mixed
The return of the other shell.

runCommand()source public

runCommand( array $argv , boolean $autoMethod false , array $extra [] )

Runs the Shell with the provided argv.

Delegates calls to Tasks and resolves methods inside the class. Commands are looked up with the following order:

  • 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.
boolean $autoMethod optional false

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

mixed
