dispatchShell() 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'] ]);

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

Returns

integer

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.
