eliminating duplicate Perl Dancer site (with and without www )
by Gabor Szabo 07 Oct '17

07 Oct '17

Hi, I am writing on the list as the subject might be relevant to every web site owner. I've just noticed both http://www.perldancer.org/ and http://perldancer.org/ serve the site. As far as I understand this is a waste of Google Juice. It is better to have only one of them serve the pages and have the other one redirect to the one serving. e.g. http://perldancer.org/ serving the content and http://www.perldancer.org/ redirecting to http://perldancer.org/ regards Gabor

The Dancefloor needs your help
by Gabor Szabo 02 Oct '17

02 Oct '17

Hi, I've just noticed the Dancefloor http://perldancer.org/dancefloor has lots of broken images. I've removed one entry where the site seems to be gone. (Moved the information from dancefloor.yml to removed_from_dancefloor.yml ) and switched 3 others to use https as thee respective sites have switched over to https. There are still many more to fix. If you have time to check other entries and send PR for https://github.com/PerlDancer/perldancer-website/ this might count as an open source contribution for https://hacktoberfest.digitalocean.com/ as well. regards Gabor ps. I've also made some changes to the code generating the website, but it seems that needs a manual restart of Starman.

Hi, I am not sure whom to alert these days so let me just send here: http://perldancer.org/ seems to be down. Both for me and the other person: http://downforeveryoneorjustme.com/perldancer.org regrads Gabor ps. Let me also update you about the eBook: The campaign reached its original goal. I've started to write and publish the book. https://leanpub.com/dancer-spa/ (I was about to list the support channels when I noticed the site being down.) Still the campaign is not over and if we can reach a higher amount I'll add another front-end to the book: In Angular, React, or Vue.

Dancer Survey 2017
by Jason A. Crome 01 Oct '17

01 Oct '17

On behalf of the Dancer Core Team, I would like to announce the availability of the Perl Dancer 2017 Survey. As Dancer 2 has become stable and matured, the Core Team is sometimes left to wonder what our community wants from us next, as it is the greatest deciding factor in focusing our efforts. What better way to answer that question than to survey you, our users, for what you like, don’t like, and what you want to see? And so we would like to ask you to share your thoughts and feelings about Dancer2, the infrastructure, and its community. Whether you are a new user or a former user, you have a lot to contribute to this survey and we would like to hear from you. What you liked about Dancer, what you do not, and what areas you feel that Dancer could improve upon. We encourage you to take the time to help us chart the roadmap for Dancer. The survey is available starting now (1-Oct-2017) and will run through 11:59pm on October 31st. Throughout the month of November, the Dancer Core Team will review and discuss the results, and by early December we will report back to the community with our findings. The survey is available on Google Forms at https://docs.google.com/forms/d/e/1FAIpQLSeFcLEcAYujouTHUJ9tHdL7FILmHEoNCWU… - share this link with your coworkers and other Dancer users, new and old, that you may know. Please take the time (20 minutes or less) to answer this survey, and help determine the future of Dancer! With thanks from the Dancer Core Team, Jason

Perl Dancer eBook - crowdfunding campaign
by Gabor Szabo 23 Sep '17

23 Sep '17

Hi there, I am planning to write an eBook on creating a "Single Page Application with Perl Dancer". In case you are not familiar with the term, a Single Page Application is one that does the HTML generation in the browser using JavaScript and that communicates with the server via AJAX requests sending JSON blobs back and forth. On the back-end it is usually a single page returning HTML and then the rest is API. (pun not intended but might work well :) I am going to use Dancer 2 for the back-end. The most well known example is Gmail, but plenty of other sites use this technique behind their authentication system. Reading this book will allow you to build such a site. In order to gauge the interest I am running a crowdfunding campaign. Support it to ensure I can write the book and that you get access to the content when the eBook is ready or even while as I am writing it. https://www.indiegogo.com/projects/ebook-single-page-application-with-perl-… regards Gabor ps. If you have questions, don't hesitate to ask me! -- Gabor Szabo http://szabgab.com/ Perl Maven http://perlmaven.com/ Perl Weekly http://perlweekly.com/

Re: [dancer-users] dancer-users Digest, Vol 91, Issue 3
by Scott H 22 Sep '17

22 Sep '17

I found out I had to be in the app directory to run the script. So you can make a sh file that cd's into the app dir to run it at least if you plan on using cron. It took me a long time to figure that out. I would be interested to see what others say.

Weird database plugin issue
by Zahir Lalani 22 Sep '17

22 Sep '17

Hi All Hoping someone can help We of course use dancer2 as a web app, but we also have some back end services that run as command line/service items. We include Dancer in those as we get a lot of the benefits. We recently started to use database calls in those backend tools but we are getting odd results. In some setups they work, in others we get this error: Use of uninitialized value in subroutine entry at /usr/local/share/perl5/Dancer2/Plugin.pm line 532. Undefined subroutine &main:: called at /usr/local/share/perl5/Dancer2/Plugin.pm line 532. I have setup a simple test that shows the failure: #!/usr/bin/perl use lib '/var/www/OMG/lib'; use Dancer2 appname => 'OMG'; use strict; use warnings; use Data::Dumper; use Dancer2::Plugin::Database; debug "begin \n"; my $sth = database->prepare("select * from public.external_application_token_get('')"); debug "end \n"; its related to the latest version of the plugin 2.17. 2.14 works. Any clues?

Re: [dancer-users] How do you minimise code in Main.pm? (looking for good Dancer2 patterns)
by Scott H 23 Aug '17

23 Aug '17

So I think the advent reply was pretty good, I wish that was in the docs as a way to do it. I started with Dancer 1 a few years ago and the tutorials and cookbook were a good start but I ran into your problem as well. I had to find a way to split up my code so my main app.pm was not just loaded with stuff. I took more of a MVC approach and made in my libs lib/models and lib/controllers folders and in my controllers put my routes for different things so I would have authentication.pm, dashboard.pm, etc.. on my models stuff I will have more of a lib perl modules scenario where my libraries and their functions exist. Such as Users.pm, Logging.pm etc... In my main app.pm I will call use controllers::dashboard; use controllers::authentication; my controllers will then use the model libs with use model::libname and then pull any functions they need out to perform the controlling of the view and then like a route load the view at the end. It works good enough for me as its laid out nice. I would consider the advent way by loading the functions directly to the route. Hopefully this gives you another idea of how to lay it out. -Scott

How do you minimise code in Main.pm? (looking for good Dancer2 patterns)
by Nathan Bailey 22 Aug '17

22 Aug '17

Hi all, I get the sense that we are using Main.pm very poorly and a bit of Dancer2 architectural insight would greatly improve the quality of our code. What is the best pattern for the breakdown between perl module/Dancer2 route handler/TT file? For example, if you have a sub-system for administrators that manages the fees tables and reports, would you put these into separate route handlers? eg. ReportsHandler.pm => Route handler for reports - Instantiates an instance of Reports.pm in it's "before" hook so we only need to do this once (or in the module itself?) - the 'view' and 'save' routes call the appropriate 'get' and 'set' methods for that table in Reports.pm and a separate handler for Fees, with an overarching Main.pm route handler that largely deals with mainstream userspace routes (any significant user workflows get their own router handler module like ReportsHandler and FeesHandler)? Ideally, I'd like all our code in the perl modules, with the route handler doing nothing but dispatch (with error handling) and the TT doing basic interface presentation. But at the moment, each route handler is 20-30 lines long - I think they should be ~5 lines long or less. An exemplar Main.pm + TT file would be very helpful! cheers, Nathan

Progress bars
by Clive Eisen 13 Aug '17

13 Aug '17

Hi I have a long running route that I would like to give feedback from via a progress bar I have installed https://github.com/shumphrey/Dancer2-Plugin-ProgressStatus <https://github.com/shumphrey/Dancer2-Plugin-ProgressStatus> to test but the demo jumps from ~2% to 100% after 30 seconds Is the demo at fault or the plugin - and in either case does anyone have a working progress bar that uses a callback for updates? TIA -- Clive Eisen GPG: 75056DD0
