In addition, here is the config for layouts: the WRAPPER path. template: "template_toolkit" charset: UTF-8 engines: template: template_toolkit: ENCODING: utf8 INCLUDE_PATH: 'views' start_tag: '<%' end_tag: '%>' WRAPPER: layouts/emails.tt Then in app code, you can refer to a template using a layout like this: my $email_body = template( 'emails/activate.tt', { real_name => $fields{ name }, recipient => $fields{ name }, }); File locations: views/emails/activate.tt views/layouts/emails.tt Cheers -- Rick

They used kernel 2.6.32 for a long while, back-porting security fixes and namespace (vitualization) improvements. Goal: be Stable and Current both at the same time. Recently (2014) they jumped to 3.10. Cheers -- Rick ref: https://en.wikipedia.org/wiki/Red_Hat_Enterprise_Linux

TT default layout
by Rick Leir 04 Nov '15

04 Nov '15

Why would there be both [% and <% in the default layout? Am I missing something? Dancer2$ more share/skel/views/layouts/main.tt <!DOCTYPE html> <html lang="en"> <head> <meta charset="<% settings.charset %>"> <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=yes"> <title>[% appname %]</title> <link rel="stylesheet" href="<% request.uri_base %>/css/style.css">  <script src="//code.jquery.com/jquery-2.1.4.min.js"></script> <script type="text/javascript">/* <![CDATA[ */ !window.jQuery && document.write('<script type="text/javascript" src="<% request.uri_base %>/javascripts/jquery.js"><\/script>') /* ]]> */</script> </head> <body> <% content %> <div id="footer"> Powered by <a href="http://perldancer.org/">Dancer2</a> <% dancer_version %> </div> </body> </html> -- Cheers -- Rick

TT

TemplateToolkit default tags are [% hi %] ref: http://search.cpan.org/~abw/Template-Toolkit-2.26/lib/Template/Manual/Confi… Dancer2 tutorial mentions this default ref: lib/Dancer2/Tutorial.pod In Dancer2 I had to configure these to get going: template: "template_toolkit" charset: UTF-8 engines: template: template_toolkit: ENCODING: utf8 INCLUDE_PATH: 'views' start_tag: '[%' end_tag: '%]' But then, the rendered template contained <% content %> in place of my tt. To get my code working, I changed my .tt files to use <% hi %> and changed the config tags: start_tag: '<%' end_tag: '%>' Is there an easier way to use Template::Toolkit in Dancer2? Yes, I should use Dancer2's simple template. Thanks Rick

(not Dancer2 related) The big issue for Perl is parallelizing your algorithms.

Help us write and publish the official PerlDancer Book!
by Alexis Sukrieh 03 Nov '15

03 Nov '15

Dear fellow PerlDancer users, developers and friends. It's been a long time since we decided to start working on a book. Different attempts were made, by different core developers, and because of many reasons, we still don't have our official book finished. We have a big plan in mind. Writing a comprehensive book that will go from the very beginning of the project's philosophy to the deepest secrets of the framework. A book any PerlDancer fan would love to have. We know what needs to be written, but we need help. One of the main reason we don't have a book yet is the lack of time and focus, and the fact that hacking the code gets always a higher priority than focusing on a long-term brain-marathon such as writing a book. But. We want this book. You want this book. It HAS TO BE :) So during the Perl Dancer 2015 conference, we chatted a bit about that, and had an idea. What about making that project a real priority, and what about trying to raise some money to give us time, group efforts, and resources to print it? Well, we did that. We launched a Kickstarter campaign to raise some funds for buying us time and letting us print the book, it's here: https://www.kickstarter.com/projects/1856511822/perldancer-book Please. If you use PerlDancer at work, speak about it to your boss, and ask about the opportunity to support the project, you'll get a printed copy of the book in the end. If you use PerlDancer for personal use, consider supporting us even with a small contribution, 5 or 10 euros can make a difference if everyone in this list contributes. In the end, when this book will be real and printed it'll be a major asset for all of us, PerlDancer users, and it will help make the project shine even more. If you like Dancer, contribute, and spread the word, share this link everywhere! :) Let's do this. Alexis, for the core team. -- Alexis Sukrieh http://twitter.com/sukria - http://blog.sukria.net "*Believe it or not, I can actually draw.*" -- Jean-Michel Basquiat

Dancer Advent Calendar 2015
by Sawyer X 01 Nov '15

01 Nov '15

Hi everyone! Last year we've ran the Dancer Advent Calendar 2014[1] containing 24 articles on how to use Dancer2, what it can do, what features it has, etc., which was very successful. We would like to have another Dancer Advent Calendar this year. This means 24 more articles. We need *you*. I'm collecting articles on topics ranging from: * Something you do in Dancer (a trick you have, a suggestion on how to use it). * Projects you made that use Dancer. * Plugins you like, plugins you wrote. * Topics I haven't thought of! The Github project for the Advent Calendar is: https://github.com/PerlDancer/advent-calendar Please feel free to submit pull requests with your articles, open issues and email back to the list (or to me) your suggestions. Anything goes. Let's have another set of great articles showing off what we have and what we can do. Thanks, Sawyer. [1] advent.perldancer.org/2014
