Hello, i recently started to use laravel and can't figure out how to solve this route

      Route::get('/', 'HomePageController@index');
      Route::get('/{lang}', 'HomePageController@index');
      Route::get('/{lang}/{all}', 'HomePageController@index');
      Route::get('/{lang}/{all}/{all2}/', 'HomePageController@index');
      Route::get('/{lang}/{all}/{all2}/{all3}/', 'HomePageController@index');
      Route::get('/{lang}/{all}/{all2}/{all3}/{all4}/', 'HomePageController@index');

Into something like this

      Route::get('/', 'HomePageController@index');
      Route::get('/*', 'HomePageController@index');

And second question, how do i insert language into already existing segments in request. Like:

mysite.com/homepage => mysite.com/en/homepage

My "before" middleware already set up to check language.

 public function handle($request, Closure $next)
{
    $locale = $request->segment(1);

    if ( ! array_key_exists($locale, $this->app->config->get('app.locales'))) {
        $segments = $request->segments();
        $segments[0] = $this->app->config->get('app.fallback_locale');
        /* insert here, if number of segments >1 */

        return redirect($segments[0]);
    }

    $this->app->setLocale($locale);

    return $next($request);
}
