[dancer-users] playing with path_info before matching routes

[WK]

Hi!

I try to build multi-language site, where i could include laguages
code into path, like this:

www.exemple.com/en/some_page
www.exemple.com/de/some_page
www.exemple.com/fr/some_page
www.exemple.com/fi/some_page
www.exemple.com/ru/some_page
etc

I want to handle part of the path after language abbreviation in one
route for every language and only render page with lang-specific
template.

I thought that best place to get language part from path is in before hook but :
* it is fired just after checking routes
* after modifiyng path_info before hook is fired again

I wrote simple code like this:

use Dancer ':syntax';
our $VERSION = '0.1';
my $lang;

hook 'before' => sub {
  my $path = request->path_info();
  if ( $path =~ s| ^/ (?<lang> [[:ascii:]]{2} ) / |/|x ) {
    $lang = $+{lang};
  }
  request->path_info( $path );
};

get '/some_page' => sub {
    template ("$lang/some_page");
};

And basically it works fine.

Still i'd like to get lang part out before trying match routes. Or is
there at least a way that before hook is not fired again?

And maybe there is even better way to achieve my goal?
