Creating a Command
Commands are created to live within add-ons, and are registered as part of the add-on process.
addon.setup.php
In order to add commands to your addon, you should add the commands parameter as an associative array to your addon.setup.php file with the handle as the key, and the class of your command as the value.
return array(
'author' => 'Awesome Developer',
'author_url' => 'https://example.com/',
'name' => 'My Amazing Module',
'description' => 'Does amazing things',
'version' => '1.0',
'namespace' => 'Awesome\AmazingModule',
'settings_exist' => true,
'commands' => [
'amazing:run' => Awesome\AmazingModule\Commands\DoThings::class,
'amazing:more-things' => 'Awesome\AmazingModule\Commands\DoMoreThings',
]
);It is best practice to namespace your commands, so as not to conflict with other addons.
Anatomy of a Command
Creating commands is simple. Each commands is built in a similar way as part of a custom add-on:
Class Structure
Your class can have any name, and should be namespaced to your addon. When creating your class, make sure to include:
use ExpressionEngine\Cli\Cli;
You class should also extend the Cli class.
use EllisLab\ExpressionEngine\Cli\Cli;
class CommandHelloWorld extends Cli {
}Required Variables
Each commmand is required to have a nummber of public variables that are required for finding and executing, as well as displaying pertinent information.
$name: The name of your Command.
$description: The basic gist of what your command does. This should be limited to one line
$summary: This is a more detailed explanation of what your command does or how to use it. This is displayed in the --help calls.
$usage: A oneline explanation of how to use your command.
$commandOptions = []: An array of available arguments and options, along with their description, as a key:value pair. ie. 'verbose,v' => 'Show all output'
In addition, the handle function is required, and does all of the work when the command is run.
use EllisLab\ExpressionEngine\Cli\Cli;
class CommandHelloWorld extends Cli {
/**
* name of command
* @var string
*/
public $name = 'Hello World';
/**
* Public description of command
* @var string
*/
public $description = 'The most basic of commands';
/**
* Summary of command functionality
* @var [type]
*/
public $summary = 'This is a sample command used to test the CLI';
/**
* How to use command
* @var string
*/
public $usage = 'php eecli.php hello';
/**
* options available for use in command
* @var array
*/
public $commandOptions = [
'verbose,v' => 'Hello world, but longer',
];
/**
* Run the command
* @return mixed
*/
public function handle()
{
// This is where the magic happens
}
}
