[dancer-users] Porting a plugin to Dancer 2

[Phin Jensen]

Hello,

I'm new to Perl, and Dancer, and I've been working on porting a plugin 
(Dancer::Plugin::Nitesi) to Dancer 2. Reading the documentation on 
Dancer2::Plugin, all I can see that is different in Dancer 2 plugins is 
the use of the $dsl variable.

So I added 'my $dsl = shift;' to every 'sub' or 'register ... => sub', 
and changed the necessary code to use the $dsl variable, but in one 
subroutine, it will only give this error:

Variable "$dsl" is not imported at 
<home>/perl5/perlbrew/perls/perl-5.16.3/lib/site_perl/5.16.3/Dancer2/Plugin/Nitesi.pm 
line 347.

This is the code for the subroutine:

> sub _update_session {
>     my $dsl = shift;
>     my ($function, $acct) = @_;
>     my ($key, $sref);
> 
>     my $settings = plugin_setting();
> 
>     # determine session key
>     $key = $settings->{Account}->{Session}->{Key} || 'user';
> 
>     $function ||= '';
> 
>     if ($function eq 'init') {
>         # initialize user related information
>         $dsl->app->session{$key} = $acct;
>     } elsif ($function eq 'update') {
>         # update user related information (retrieve current state 
> first)
>         $sref = $dsl->app->session{$key};
> 
>         for my $name (keys %$acct) {
>             $sref->{$name} = $acct->{$name};
>         }
> 
>         $dsl->app->session->{$key} = $sref;
> 
>         return $sref;
>     }
>     elsif ($function eq 'destroy') {
>     # destroy user related information
>     $dsl->app->session->{$key} = undef;
>     }
>     else {
>     # return user related information
>     return $dsl->app->session($key);
>     }
> };

I've tried changing the $dsl declaration to all of these:

> my ($dsl, $function, $acct) = @_;
> my ($function, $acct, $dsl) = @_;
> my ($function, $dsl, $acct) = @_;
> my $dsl = shift @_;

Nothing seems to work.

I've attached the whole file. I'm pretty sure it's the only file I've 
changed, and I've probably made a mess of it.

Any help would be much appreciated, again, I'm new to Perl and Dancer, 
so I don't really know what I'm doing.

Thanks.
