As the -.psgi script is now obsolete, we wanted to simplify the middleware -configuration for users not familiar with Plack. - -It's now possible to load a middleware by adding it to your -configuration: - -#+BEGIN_EXAMPLE - plack_middlewares: - Debug: - - panels - - - - DBITrace - - Memory - - Timer -#+END_EXAMPLE - -*** YAPC::Eu 2010 - -During YAPC::EU, I've been happy to meet with -[[http://github.com/squeeks][squeeks]], -[[http://blogs.perl.org/users/sawyer_x/][sawyer]] and -[[http://github.com/mberends][Martin Berends]]. Sadly, we didn't have -much time to talk and do some coding. - -I had already met Martin during the FPW, where he started to port Dancer -to Perl6. His first objective is to have -[[http://github.com/mberends/http-server-simple][HTTP::Server::Simple]] -work. I was really impressed with his works; if I manage to find some -spare time soon, I will join his effort. - -*** Dancer's application - -In august, [[http://www.sukria.net/][Alexis]] brought a big effort to -refactor the core of Dancer, to add the possibility to "plug" components -to your application. This required a lot of rewriting, but in the -meantime, we added more tests to ensure nothing would break. - -With this feature, you can do the following: - -#+BEGIN_SRC perl - package myapp::forum; - use Dancer ':syntax'; - - before => sub { - ... - }; - - get '/' => sub { - ... - }; - - package myapp:blog; - use Dancer ':syntax'; - - load_app 'myapp::forum', prefix => '/forum'; - - before => sub { - ... - }; - - get '/' => sub { - ... - }; -#+END_SRC - -Now you can request */* and */forum*. The before filter declared in the -package *myapp::forum* will be executed when the */forum* path is -matched, and the filter in *myapp::blog* will be executed for */*. - -*** QA - -The weekend following the YAPC::EU, we held a small hackaton/QA day on -irc. Not many people were present, but we managed to achieve some -results: - -- reached the 1K tests -- documentation cleanup -- added Hooks -- improved our code coverage - -Today our code average is over 92%, and we have more than 1200 tests. - -With the new hook system, two new keywords have been added: -*before\_template* and *after*. They work as the *before* keyword, -except the *before\_template* is executed before sending the tokens to -the template, so you can modify them (a small example can be found in -the -[[http://git.lumberjaph.net/p5-dancer-plugin-18n.git/][Dancer::Plugin::i18n]]). -The *after* is executed before the response is sent to the user. - -Sukria has also set up an autobuild system for our two main branches. -Every 15 minutes, the test suite is executed when there is a new commit, -and builds a report. Code coverage is also measured, so we can always -know the state of our various development cycles. - -*** WebSocket - -This is the question that came back from time to time: when/will Dancer -support websocket ? - -We investigated various ways to do this: - -- new async. handler -- writing our own implementation -- ... - -I didn't want to write a websocket implementation for Dancer, as the -spec are not yet final and it's not easy to do. Thanks to -[[http://github.com/clkao][clkao]], we didn't have to care about all -this, as he already wrote a Plack middleware for this: -[[http://search.cpan.org/perldoc?Web::Hippie::Pipe][Web::Hippie]]. - -So, what we did, is to use this middleware and add some syntactic sugar -so people can use it easily in their applications. A small application -is available [[http://git.lumberjaph.net/p5-dancer-chat.git/][here]]. - -This is not yet complete, it's only available in the 'devel' branch, and -subject to change. A small code sample: - -#+BEGIN_SRC perl - websocket '/new_listener' => sub { - my $env = request->env; - my $room = $env->{'hippie.args'}; - my $topic = $env->{'hippie.bus'}->topic($room); - $env->{'hippie.listener'}->subscribe($topic); - }; - - websocket '/message' => sub { - my $env = request->env; - my $room = $env->{'hippie.args'}; - my $topic = $env->{'hippie.bus'}->topic($room); - - my $msg = $env->{'hippie.message'}; - $msg->{time} = time; - $msg->{address} = $env->{REMOTE_ADDR}; - $topic->publish($msg); - }; -#+END_SRC - -As you can see, a lot of stuff can be improved quite easily in terms of -syntax. - -*** Deployment - -We're also in the process of reworking our current Deployment -documentation. Lots of people are trying to deploy Dancer using various -configurations, and not all are well documented, or don't work as -expected. If you use Dancer, and have deployed an application in a way -not documened in our Deployement documentation, please join us on irc -(#dancer on irc.perl.org) or contact us on the mailing list, or even -better, send us a patch, so we can improve this part. - -*** Future - -There is also our next Dancer's meeting meeting to organize, at the end -of Septembre. - -In October will take place the 2nd OSDC.fr, where I will talk about -Plack, and alexis will present Dancer. - -I want to thank my company ([[http://linkfluence.net][Linkfluence]]) and -my boss ([[http://twitter.com/cmaussan][Camille]]) for giving me time to -code on Dancer at work. - -As always, thanks to blob for reviewing my (slightly improving) english -:) |
