Class

ComposerInspector

Defines a class to get information from Composer.

Namespace

Drupal\package_manager

Code

protected function show(string $working_dir) : array {
    $data = [];
    $options = [
        'show',
        '--format=json',
        "--working-dir={$working_dir}",
    ];
    // We don't get package installation paths back from `composer show` unless
    // we explicitly pass the --path option to it. However, for some
    // inexplicable reason, that option hides *other* relevant information
    // about the installed packages. So, to work around this maddening quirk, we
    // call `composer show` once without the --path option, and once with it,
    // then merge the results together. Composer, for its part, will not support
    // returning the install path from `composer show`: see
    // https://github.com/composer/composer/pull/11340.
    $this->runner
        ->run($options, callback: $this->processCallback
        ->reset());
    $output = $this->processCallback
        ->parseJsonOutput();
    // $output['installed'] will not be set if no packages are installed.
    if (isset($output['installed'])) {

            $data[$installed_package['name']] = $installed_package;
