Console Configuration Helper implementation.

Install

Via Composer

$ composer require phlib/console-configuration

Configuration Helper

Adds the -c path/to/config.php parameter to the console application and makes it easily accessible to all commands. This is most useful for third party libraries which rely on the configuration being specified from the options.

Basic Usage

// your usual cli setup script

use Phlib\ConsoleConfiguration\Helper\ConfigurationHelper;

$app = new Application('my-cli');
$app->setCommands(['...']);
$helper = ConfigurationHelper::initHelper(
    $app,
    $default = ['host' => 'localhost'],
    $options = []
);
$app->run();

class MyCommand extends Command
{
    '...'

    protected function createMyObjectInstance()
    {
        $config = $this->getHelper('configuration')->fetch();
        return new MyObjectInstance($config);
    }
}

Options

You can specify some options to setup the helper through the initHelper static method.

Name	Type	Default	Description
`name`	String	`'config'`	The name of the option on the command line.
`abbreviation`	String	`'c'`	The abbreviation of the option on the command line.
`description`	String	`'...'`	The associated description for the option.
`filename`	String	`'cli-config.php'`	The filename that will be detected if no name is specified.

ConfigurationHelper::initHelper($app, null, [
    'name' => 'config-option',
    'filename' => 'my-cli-config.php',
]);

Defaults

With no default (null) specified, the fetch method returns false. You can specify a default configuration using the setDefault method or through the initHelper static method.

$helper->setDefault(['host' => 'localhost']);

ConfigurationHelper::initHelper(
    $app,
    ['host' => 'localhost'],
    ['filename' => 'service-name.php']
);

Use Case: Autodetect with no command line option

$app = new Application('my-cli');
$app->setCommands(['...']);
$app->getHelperSet()->set(new ConfigurationHelper('config', 'my-config.php'));
$app->run();
