Modules paths.

[annavanbiemen]

The Modules component should have some way to get paths to modules (preferably the path to the directory in which the src or classes directory of the package are contained).

    /**
     * Get module paths indexed by name
     *
     * When a file or directory is given, paths will be returned
     * to this specific file or directory within the modules, but
     * only for modules in which it actually exists.
     *
     * @param string $to File or directory
     * @return array
     */
    public function paths($to = null)
    {
        $paths = array_map(function (string $class) {
            return dirname(dirname((new ReflectionClass($class))->getFileName()));
        }, $this->classes);;

        if ($to) {
            $paths = array_filter(array_map(function (string $path) use ($to) {
                return $path . DIRECTORY_SEPARATOR . trim($to, DIRECTORY_SEPARATOR);
            }, $paths), 'file_exists');
        }

        return $paths;
    }
