Installation

Using Composer

composer require fyre/command

In PHP:

use Fyre\Command\CommandRunner;

Basic Usage

• $container is a Container.
• $inflector is an Inflector.
• $loader is a Loader.
• $io is a Console.
• $eventManager is an EventManager.
• $typeParser is an TypeParser.

$runner = new CommandRunner($container, $inflector, $loader, $io, $eventManager, $typeParser);

Autoloading

It is recommended to bind the CommandRunner to the Container as a singleton.

$container->singleton(CommandRunner::class);

Any dependencies will be injected automatically when loading from the Container.

$runner = $container->use(CommandRunner::class);

Methods

Add Namespace

Add a namespace for loading commands.

• $namespace is a string representing the namespace.

$runner->addNamespace($namespace);

All

Get all available commands.

$commands = $runner->all();

Clear

Clear all namespaces and loaded commands.

$runner->clear();

Get Namespaces

Get the namespaces.

$namespaces = $runner->getNamespaces();

Handle

Handle an argv Command.

• $argv is an array containing the CLI arguments.

$code = $runner->handle($argv);

Has Command

Determine whether a command exists.

• $alias is a string representing the command alias.

$hasCommand = $runner->hasCommand($alias);

Has Namespace

Determine whether a namespace exists.

• $namespace is a string representing the namespace.

$hasNamespace = $runner->hasNamespace($namespace);

Remove Namespace

Remove a namespace.

• $namespace is a string representing the namespace.

$runner->removeNamespace($namespace);

Run

Run a Command.

• $alias is a string representing the command alias.
• $arguments is an array containing arguments for the command, and will default to [].

$code = $runner->run($alias, $arguments);

Command options will be parsed from the provided arguments.

Commands

Custom commands can be created by extending \Fyre\Command\Command, suffixing the class name with "Command", and ensuring a run method is implemented.

Any dependencies will be resolved automatically from the Container.

The run method should return an integer representing the command exit code. The class constants Command::CODE_SUCCESS and Command::CODE_ERROR can be used.

Aliases

You can define $alias and $description properties on the command. If no $alias is a provided, the command class name will be used (converted to snake_case).

Options

You can also define an $options array on your custom commands, which will be used by the CommandRunner to parse the arguments and prompt for input if required.

• prompt is a string representing the prompt text, and will default to "".
• values is an array containing the values, and will default to null.
• required is a boolean indicating whether a value must be provided, and will default to false.
• as is a string representing the value type, and will default to null.
• default is the default value, and will default to true.

protected array $options = [
    'name' => [
        'prompt' => 'What is your name?',
        'required' => true,
    ],
    'color' => [
        'prompt' => 'What is your favorite color?',
        'values' => [
            'red',
            'green',
            'blue',
        ],
    ],
    'confirmed' => [
        'prompt' => 'Do you want to continue?',
        'as' => 'boolean',
        'required' => true,
    ],
];

public function run(string $name, string|null $color, bool $confirmed): int;

If an option is marked as required and not provided as an argument, the CommandRunner will prompt for the value, otherwise the default value will be used.
