=cut

sub begin : Private {
    my ( $self, $c ) = @_;
    if($c->sessionid && $c->session->{lang}) {
        $c->languages([$c->session->{lang}]);
    }

    }
}

=head2 default (global)

Default action - display the error page (message.tt), for example when a
nonexistent action was requested (like C</parent_page/child_page.fireworks>).

=cut

sub default : Path {
    my ( $self, $c ) = @_;
    $c->res->status(404);
    $c->stash->{message} = $c->loc(
        'The requested URL was not found: x',
        '<span class="error_detail">' . $c->stash->{pre_hacked_uri} . '</span>'
    );
    $c->stash->{template} = 'message.tt';
}

=head2 set_lang

(Re)set language of current session.

=cut

sub set_lang :Global {
    my ($self,$c) = @_;
    $c->session->{lang}=$c->req->params->{lang};
    $c->res->redirect($c->req->params->{redir});
}

=head2 render

Finally, use ActionClass RenderView to render the content.

=cut

sub render : ActionClass('RenderView') {
    my ($self) = shift;
    my ($c)    = @_;
    $c->stash->{path} ||= '/';
}

=head2 end (builtin)

At the end of any request, forward to view unless there is a template
or response, then render the template. If param 'die' is passed,
show a debug screen.

=cut

sub end : Private {
    my ( $self, $c ) = @_;

    my $theme=$c->pref('theme');
    # if theme doesn't exist
    if ( ! -d  $c->path_to('root','static','themes',$theme)) {
       $theme='default';
       $c->pref('theme',$theme);
    }
    $c->stash->{additional_template_paths} =
        [ $c->path_to('root','themes',$theme) ];

    $c->req->uri->path( $c->stash->{pre_hacked_uri}->path )
        if ref $c->stash->{pre_hacked_uri};
    $c->forward('render');
}

=head2 auto

Runs for all requests, checks if user is in need of validation, and
intercepts the request if so. Also, if the requested page doesn't exist,
prevents any other actions from running, and detaches straight to
L<MojoMojo::Controller::Page/suggest>.

=cut

sub auto : Private {
    my ( $self, $c ) = @_;
    
    # Prevent most actions from running on non-existent pages. This fixes issues #36 and #80.
    # 'render' should be allowed so that jsrpc/render can be used to preview newly created pages while the first version is being typed in
    my $proto_pages = $c->stash->{proto_pages};
    $c->detach('MojoMojo::Controller::Page', 'suggest')
        if ($proto_pages && @$proto_pages && $c->action->name !~ /^(edit|render|login|logout|register|recover_pass)$/);

    if ( $c->pref('enforce_login') ) {
        # allow a few actions
        if ( grep $c->action->name eq $_, qw/login logout recover_pass register/ ) {
            return 1;
        }
        if ( !$c->user_exists ) {
                $c->res->redirect(
                        $c->uri_for(     
                                $c->stash->{path} . '.login' # send them to the login for this page
                        )
                );
        }
    }

    return 1 unless $c->stash->{user};
    return 1 if $c->stash->{user}->active != -1;
    return 1 if $c->req->action eq 'logout';
    $c->stash->{template} = 'user/validate.tt';
}

=head2 exit

A way to exit from MojoMojo.  Useful when testing leaks.

=cut

sub exit : Local {
    my ($self, $c) = @_;
    if ($ENV{MOJOMOJO_EXIT_OK}) {
        exit(0);
    }
    else {
       # $c->stash( template => 'error.tt' );
        $c->res->status (403); # forbidden
        $c->res->body('EXIT NOT OK');
        $c->detach();
    }
}
