It's amazing how little code is needed with Moo and the role. Mostly, it just delegates everything. https://github.com/dagolden/dancer-sessionfactory-memcached/blob/master/lib… David -- David Golden <xdg(a)xdg.me> Take back your inbox! → http://www.bunchmail.com/ Twitter/IRC: @xdg

how should I set a setting while parsing command line options (GH#393)
by Gideon D'souza 09 Oct '13

09 Oct '13

Hey folks, So I'm working on fixing issue #393: https://github.com/PerlDancer/Dancer2/issues/393 I'm sorry to have gotten jammed up with such a simple task. I ran into a small issue which might relate to other things going on. (1) I cannot use setting(port => 1234) or setting(environment => "stage") inside GetOpt like Dancer1. It fails. Here is the line that fails: https://github.com/gideondsouza/Dancer2/blob/pr/command_line_support/lib/Da… @mst did point out this is incorrect, I should point to the config setting on the app instance. A larger problem here is that this doesn't work either. (2) $app->setting(..) or $runner->setting(..) don't work. See : https://github.com/gideondsouza/Dancer2/blob/pr/command_line_support/lib/Da… What also perplexed me is that if I put a breakpoint at a line inside Dancer2::import it wouldn't stop and just go and run the server. So what should I do here? Setting $ENV{} works. Should I do this? Am I doing something wrong? Is there anything else I should fix first? Regards, Gideon

Dancer1 plugins and Dancer2 plugins
by Slavik Goltser 07 Oct '13

07 Oct '13

I could not find any information on this, but what is the recommended way of migrating Dancer1 plugins to Dancer2? Is it to add version checking while keeping the Dacer1 naming or is it recommended to rename the plugins to Dancer2::Plugin... ? I apologize if I am uncovering some heated debates relating to the subject.

Tiny problem with sessions in a Dancer2 plugin
by Gideon D'souza 05 Oct '13

05 Oct '13

I would really really appreciate some help on this tiny problem I'm having. I'm porting my Github Authentication plugin into Dancer2, but for the life of my I can't get it to work and I've been stuck for days now on this. *Everything works*, but it's just the the session value that is set from within the plugin is undef inside the application. Here is the code narrowed down, the Plugin: https://gist.github.com/gideondsouza/6718246#file-dancer2_plugin_gh_auth-pl… I set the session there, all works great. Now, the session is undef here in the app: https://gist.github.com/gideondsouza/6718224#file-test_github_plugin-pl-L14 Is it because I'm calling the init() method here and this method setups up a route? https://gist.github.com/gideondsouza/6718224#file-test_github_plugin-pl-L9 Is there a way to add routes inside a plugin, on init or something like that? Or perhaps it's something else I've missed? Any reply or pointers appreciated. Gideon

Who is using [%prefix%] in templates?
by Henk van Oers 04 Oct '13

04 Oct '13

I do. I have a hook: hook before_template => sub { my $tokens = shift; $tokens->{prefix} = prefix; }; Is this a good candidate to implement in https://metacpan.org/module/Dancer::Template::Abstract as default Dancer inject like qw(perl_version dancer_version settings request params vars session); ? -- Henk

Dancer2::Template::Mason2
by Slavik Goltser 01 Oct '13

01 Oct '13

Hi everyone, I have done some work on migrating the Dancer::Template::Mason2 plugin to Dancer2. The code is located on github: https://github.com/theslava/perl-dancer2-template-mason2 I would love to hear some feedback (I am sure backwards compatibility with Dancer1 will be one of the points). Please keep in mind that I am very new to Moo(se)/Dancer and there are some things that I have done in the code that I do not completely understand. This code is based directly on Jonathan's code so the license for this plugin is the same as his. I think the license he mentions in his code is the Artistic License 2.0 ... I have sent him an e-mail asking for clarification. Enjoy, Slava

Geting RuntimeError when calling pass
by Jonathan Harden 29 Sep '13

29 Sep '13

Hello fellow Dancer users, I've been programming perl quite a few years now but am starting a new job soon, they use Dancer so I thought I would have a bash at it before I start there. I've been having a play at making something and I'm loving Dancer but I seem to have hit on a problem, I'm not sure if it's a bug in Dancer (it almost never is I know!) or if I am misunderstanding how I should be using pass but here it is anyway: I'm using Module::Load to load a module (containing routes) at runtime and then calling pass. If there are no matching routes this causes a RuntimeError. Example: $ cat bin/app.pl #!/usr/bin/env perl use Dancer; use Demo; dance; __END__ $ cat lib/Demo.pm package Demo; use Dancer qw( :syntax !load ); use Module::Load; any '/Monitoring/*?' => sub { my $module = "Monitoring"; load $module; pass(); }; true; __END__ $ cat lib/Monitoring.pm package Monitoring; use Dancer ':syntax'; prefix '/Monitoring'; get '/' => sub { return 'Monitoring Service'; }; get '/ping' => sub { return time; }; true; __END__ Calling domain.com/Monitoring/ping results in a timestamp as you would expect Calling domain.com/Monitoring/ returns the string "Monitoring Service". Calling domain.com/Monitoring/foo results in a Runtime Error where I would have expected to receive a 404 error Runtime Error runtime error Can't call method "run" on an undefined value at /usr/share/perl5/Dancer/Route.pm line 212. /usr/share/perl5/Dancer/Route.pm around line 212 209 $response->pass(0); 210 if ($self->next) { 211 my $next_route = $self->find_next_matching_route($request); 212 return $next_route->run($request); 213 } 214 else { 215 Dancer::Logger::core('Last matching route passed!'); Stack main in -e l. 0 main in -e l. 0 Plack::Handler::Apache2 in /usr/share/perl5/Plack/Handler/Apache2.pm l. 91 Plack::Handler::Apache2 in /usr/share/perl5/Plack/Handler/Apache2.pm l. 66 Dancer::Handler in /usr/share/perl5/Dancer/Handler.pm l. 123 Dancer::Handler in /usr/share/perl5/Dancer/Handler.pm l. 76 Dancer::Handler in /usr/share/perl5/Dancer/Handler.pm l. 113 Try::Tiny in /usr/share/perl5/Try/Tiny.pm l. 100 Dancer::Exception in /usr/share/perl5/Dancer/Exception.pm l. 47 Dancer::Exception in /usr/share/perl5/Dancer/Exception.pm l. 35 Dancer::Handler in /usr/share/perl5/Dancer/Handler.pm l. 107 Dancer::Object in /usr/share/perl5/Dancer/Object.pm l. 16 Dancer::Error in /usr/share/perl5/Dancer/Error.pm l. 37 Dancer::Error in /usr/share/perl5/Dancer/Error.pm l. 276 I've not posted all of the RuntimeError since it contains sensitive information about my config file and server. If the rest is needed I can spend some time to run up a clean version without anything important in. I'm using the version of Dancer which comes with Debian 7. $ apt-cache show libdancer-perl Package: libdancer-perl Version: 1.3095+dfsg-1 I'm using apache2 with Plack::Handler::Apache2 to run the Dancer application. My real application is more complex than this but I knocked this one up so it would demo the problem with as little code as possible. Does anyone know why this RuntimeError occurs, and perhaps how I can avoid it in the situation where I need to load a module dynamically which contains routes. Alternatively should I report this on the Dancer github and then try and fix it? Thanks, Jonathan

Dancer2 - New App - compilation aborted
by Gert van Oss 20 Sep '13

20 Sep '13

Starting to have closer look at using Dancer2 I found the following. I installed everything as documented (on OS-X with perl v.5.18.1). Then I do: dancer2 -a MyApp && cd MyApp Next perl bin/app.pl Can't locate MyApp.pm in @INC (you may need to install the MyApp module) (@INC contains: /Users/gvo/perl5/perlbrew/perls/dancer_development/lib/site_perl/5.18.1/darwin-2level /Users/gvo/perl5/perlbrew/perls/dancer_development/lib/site_perl/5.18.1 /Users/gvo/perl5/perlbrew/perls/dancer_development/lib/5.18.1/darwin-2level /Users/gvo/perl5/perlbrew/perls/dancer_development/lib/5.18.1 .) at bin/app.pl line 3. BEGIN failed--compilation aborted at bin/app.pl line 3. All this did work for Dancer (number one). Can anybody explain me how to solve this. Best, Gert
