dancer2's prototype is there, feedback needed
by sukria 05 Oct '12

05 Oct '12

Hi there, I am very glad and proud to announce here that I've came up with a prototype of dancer2 that pleases me enough to be advertised. -*- https://github.com/sukria/dancer2 -*- dancer2 is a complete rewrite of Dancer aiming at providing the same awesomeness with the following major changes: - no more globals in the core - 100% object-oriented backend (based on Moo) - better scoping for sub-applications - better design (no more encapsulation violations, Law of Demeter, ...) The prototype I've pushed to GitHub currently covers ~80% of the DSL of Dancer. It's able to run simple applications (it can run the PerlDancer.org website for instance). Of course, with your real-life applications, it will break in many places in this current shape, and this is where you can help. I'd like to have as many reports as possible regarding upgrades tests. You can test very easily your app with dancer2: $ git clone http://github.com/sukria/dancer2.git $ cd YOUR_APP $ perl -I../dancer2/lib bin/app.pl Also, important to know: most of the plugins may not be working well. Thanks a lot ;)

a couple of questions re. Plugins
by Puneet Kishor 02 Dec '11

02 Dec '11

1. Does a plugin have to reside under Dancer::Plugin::MyPlugin? Or, can it be situated anywhere, like, for example, under app/lib? 2. Is it possible to call a method in the application from within MyPlugin? Here is what I mean -- In my app.pm, I have a method called sub opts { } I typically set a bunch of template options in the above sub routine, and use it like so get '/' => sub { my $opts = opts(); template 'index', $opts; }; I am creating plugin that automatically generates a web page like so return engine('template')->apply_layout($content); I would like to run `app::opts()`, and pass the $opts to the template from within the plugin. I am at a loss how to do that. -- Puneet Kishor

I must be doing something wrong, but don't know what. I have the following database definitions in my config file plugins: Database: connections: pg: driver: 'Pg' .. .. mysql: driver: 'mysql' .. .. Then, in my code my $sth1 = database->('pg')->prepare(qq{ SELECT blah }); $sth1->execute(); and my $sth2 = database->('mysql')->prepare(qq{ SELECT blah }); $sth2->execute(); But, I get the following error in my log file Can't connect to data source 'dbi:' because I can't work out what driver to use (it doesn't seem to contain a 'dbi:driver:' prefix and the DBI_DRIVER env var is not set) at /opt/local/lib/perl5/site_perl/5.14.1/Dancer/Plugin/Database.pm line 161 in /opt/local/lib/perl5/site_perl/5.14.1/Dancer/Handler.pm l. 90 I am using Dancer::Plugin::Database 1.51 -- Puneet Kishor

Advent Calendar time again!
by David Precious 27 Nov '11

27 Nov '11

Hi all, It's about time we started preparing for the 2011 advent calendar - I think we should do it again this year as it was successful last year and drew a lot of valuable attention to the project. We still have the app from last year, and luckily we built it to support multiple years nicely enough, so this year all we need to do is write the articles (although, to be fair, that's the harder and more time-consuming part! :) ) I've renamed the repository from advent-calendar-2010 to just advent-calendar - you can find it at: https://github.com/PerlDancer/advent-calendar For anyone who didn't see last year's advent calendar, it's at: http://advent.perldancer.org/2010 I've added some article ideas to the README in the repo; additional ideas and volunteers to write would be very gratefully appreciated! Submissions can be made as pull requests, mails to the list or to me personally; I'm happy to help curate the work towards this in order to get it sorted in time for the 1st December. I think, among other interesting posts, we should be able to manage a few posts on what Dancer2 is going to bring, and decision decisions etc. Cheers Dave P -- David Precious ("bigpresh") http://www.preshweb.co.uk/ "Programming is like sex.

dancerctl poll ;)
by Nick Knutov 24 Nov '11

24 Nov '11

Which is better? dancerctl app start|stop [environment] or dancerctl start|stop app [environment] Or may be it's better to have reserved words (start|stop|restart|etc) and try to autodetect first two parameters which one is app_name and which one is action? Also, the new stable version will be available soon. The new and much better documentation is already available at https://github.com/knutov/dancerctl/tree/dev -- Best Regards, Nick Knutov http://knutov.com ICQ: 272873706 Voice: +7-904-84-23-130

Bug in Dancer1 (devel branch) - no request->header inside routes
by Perlover 23 Nov '11

23 Nov '11

Hello, I found a bug as i think in Dancer1 -> devel branch Please take a look at Dancer::Deployment -> Running multiple apps with Plack::Builder my $app2 = sub { my $env = shift; local $ENV{DANCER_APPDIR} = '/Users/franck/tmp/app2'; # 'mount_at' is used to guarantee that the routes of the applications do # not intersect load_app "app2", mount_at => "/app2"; Dancer::App->set_running_app('app2'); setting appdir => '/Users/franck/tmp/app2'; Dancer::Config->load; my $request = Dancer::Request->new( env => $env ); ^^^^^^^^^^^^^^ Here $request->{headers} will be undef because Dancer::SharedData->headers will return undef (my variable $_headers will be undef) Dancer->dance($request); ^^^^^^^ Inside here in Dancer::Handler in the sub handle_request will be initialized $_headers of Dancer::SharedData but $request object will be keep {headers} as undef }; Thus in PSGI variant we will not get any headers through request->header('...') I can try to make patch for this Perlover
