Commands

You can create some commands to call your functions or services to automate some jobs in crontab for example.

Create a command

You need to implement \Berlioz\CliCore\Command\CommandInterface interface or extends \Berlioz\CliCore\Command\AbstractCommand abstract class.

Representation of interface:

/**
 * Interface CommandInterface.
 *
 * @package Berlioz\CliCore\Command
 */
interface CommandInterface
{
    /**
     * Get short description.
     *
     * @return string|null
     */
    public static function getShortDescription(): ?string;

    /**
     * Get description.
     *
     * @return string|null
     */
    public static function getDescription(): ?string;

    /**
     * Get options.
     *
     * Must return an array of options.
     *
     * @return \GetOpt\Option[]
     * @see http://getopt-php.github.io/getopt-php/options.html
     */
    public static function getOptions(): array;

    /**
     * Get operands.
     *
     * Must return an array of operands.
     *
     * @return \GetOpt\Operand[]
     * @see http://getopt-php.github.io/getopt-php/operands.html
     */
    public static function getOperands(): array;

    /**
     * Run command.
     *
     * @param \GetOpt\GetOpt $getOpt
     *
     * @return void
     */
    public function run(GetOpt $getOpt);
}

Use arguments

Berlioz commands uses ulrichsg/getopt-php composer package to manage CLI arguments. So to use arguments, \Berlioz\CliCore\Command\CommandInterface::getOptions() method must return an array of \GetOpt\Option objects.

Example:

public static function getOptions(): array
{
    return [
        (new Option('f', 'filter', GetOpt::OPTIONAL_ARGUMENT))
            ->setDescription('Filter')
            ->setValidation('is_string'),
        (new Option(null, 'nb', GetOpt::OPTIONAL_ARGUMENT))
            ->setDescription('Number of results')
            ->setValidation('is_numeric')
    ];
}

Declare a command

You need to declare each commands in a commands.json file in your configuration directory.

Example of file:

{
    "commands": {
        "myproject:foo": "\\MyProject\\Command\\FooCommand",
        "myproject:bar": "\\MyProject\\Command\\BarCommand"
    }
}

Call a command

An executable is available in the binary directory of Composer to call commands.

Examples:

$ cd /my/project/directory
$ vendor/bin/berlioz myproject:foo
Printed result!
$ vendor/bin/berlioz myproject:bar --arg1 "Test" -aze
Printed result of second command!
