To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.

composer require wyrihaximus/get-in-packages-composer.jason

The following examples are made with the following composer.json in mind:

{
    "extra": {
        "react-inspector": {
            "metrics": [
                "ticks.future.current",
                "ticks.future.total",
                "ticks.future.ticks",
                "signals.current",
                "signals.total",
                "signals.ticks"
            ],
            "reset": {
                "ticks": [
                    "ticks.future.ticks",
                    "signals.ticks"
                ]
            }
        },
        "reactive-apps": {
            "command": {
                "ReactiveApps\\Command\\HttpServer\\Command": "src/Command"
            },
            "config": [
                "etc/config/app.php",
                "etc/config/http-server.php",
                "etc/config/supervisor.php"
            ]
        }
    }
}

Get the config for the given key for all packages that have it. Passed the Package instance as key and config from composer.json as value:

/**
 * @var Composed\Package $package
 * @var mixed            $config
 */
foreach (GetInPackages::composer('extra') as $package => $config) {
    $packagesConfig->add($package, $config);
}

Same as GetInPackages::composer but yield from's the items in each package:

foreach (GetInPackages::fromComposer('extra.react-inspector.metrics') as $item) {
    // $item: [
    // ticks.future.current,
    // ticks.future.total,
    // ticks.future.ticks,
    // signals.current,
    // signals.total,
    // signals.ticks,
    // ]
}

Building on GetInPackages::composer, GetInPackages::composer_path iterates over all the config items per package coming back from GetInPackages::composer and gets the full path for the given items value. This is handy for example configuration autodiscovery:

foreach (GetInPackages::composerPath('extra.reactive-apps.config') as $path) {
    $config->loadFromFile($path);
}

Works the same as GetInPackages::composer_path but instead of down a full path per item it uses that full path for the item as key and the items key and value. Handy for scanning a file directory and having the namespace for the root present:

foreach (GetInPackages::composerWithPath('extra.reactive-apps.command') as $path => $namespacePrefix) {
    $commands->scan($path, $namespacePrefix);
}
