从一个数组建立一个ConsoleOptionParser

本文介绍如何使用ConsoleOptionParser::buildFromArray方法来简化子命令选项解析器的创建过程。通过一个数组定义解析器规范，可以轻松设置帮助信息、描述、参数等关键信息。

ConsoleOptionParser::buildFromArray($spec)

正如前面提到的,当创建子命令选项解析器,您可以定义解析器规范作为该方法的一个数组。这可以帮助简化构建子命令的解析器,因为一切都是一个数组:

$parser->addSubcommand('check', array(
    'help' => __('Check the permissions between an ACO and ARO.'),
    'parser' => array(
        'description' => array(
            __("Use this command to grant ACL permissions. Once executed, the "),
            __("ARO specified (and its children, if any) will have ALLOW access "),
            __("to the specified ACO action (and the ACO's children, if any).")
        ),
        'arguments' => array(
            'aro' => array('help' => __('ARO to check.'), 'required' => true),
            'aco' => array('help' => __('ACO to check.'), 'required' => true),
            'action' => array('help' => __('Action to check'))
        )
    )
));

在解析器规格,您可以定义键参数,选项,描述和跋。你不能定义子命令在一个数组风格建筑。参数的值,选择,应该遵循的格式ConsoleOptionParser::addArguments()和ConsoleOptionParser::addOptions()使用。您还可以使用buildFromArray自行建立一个选项解析器:

public function getOptionParser() {
    return ConsoleOptionParser::buildFromArray(array(
        'description' => array(
            __("Use this command to grant ACL permissions. Once executed, the "),
            __("ARO specified (and its children, if any) will have ALLOW access "),
            __("to the specified ACO action (and the ACO's children, if any).")
        ),
        'arguments' => array(
            'aro' => array('help' => __('ARO to check.'), 'required' => true),
            'aco' => array('help' => __('ACO to check.'), 'required' => true),
            'action' => array('help' => __('Action to check'))
        )
    ));
}
