Dancer book - available now
by Gabor Szabo 17 Sep '15

17 Sep '15

Hi, as you might know I have been writing and publishing lots of beginner and advanced level articles on the Perl Maven site. Some of the articles are available to everyone to read, others are only available to the "Perl Maven Pro" subscribers. As I understand not everyone who might want to read the Dancer articles wants to have a monthly subscription, so I have created an e-book from all the Dancer articles listed on http://perlmaven.com/dancer page. I've also added an (almost hidden) button at the bottom of that page that will let you buy the book for $15. Of course if you'd like to provide ongoing support to the Perl Maven site then you can also subscribe to the Perl Maven Pro http://perlmaven.com/pro/ and get access to over 100 advanced articles and screencasts. regards Gabor ps. If you encounter any problems, or have any question, please send me an e-mail privately. -- Gabor Szabo http://szabgab.com/ Code Maven http://code-maven.com/ Perl Maven http://perlmaven.com/ Perl Weekly http://perlweekly.com/

Executing Hooks in dancer2
by Rubén Amórtegui 17 Sep '15

17 Sep '15

Hello, I'm having some issues with the hooks, because it seems that runs more than one time each time that I'm calling from my Dancer2 application. I have this plugin: -- package Dancer2::Plugin::MyPluginTest; use Dancer2::Plugin; register_hook 'my_new_hook'; register new_function => sub { execute_hook 'my_new_hook'; }; register_plugin; -- And I have this Dancer test application: -- use strict; use warnings; use Test::More; use Plack::Test; use HTTP::Request::Common; { package MyTestApp; use Dancer2; use Dancer2::Plugin::MyPluginTest; my $var = 0; get '/' => sub { new_function; $var; }; hook 'my_new_hook' => sub { $var++; debug "Executing hook - $var"; }; }; my $test = Plack::Test->create( MyTestApp->to_app ); my $res = $test->request( GET '/' ); is( $res->content, '1', 'Var is 1 after one call on /' ); done_testing(); -- When I run the test, the hook it's executed twice. -- [MyTestApp:6554] debug @2015-09-17 08:26:33> Executing hook - 1 in plugin.pl l. 21 [MyTestApp:6554] debug @2015-09-17 08:26:33> Executing hook - 2 in plugin.pl l. 21 not ok 1 - Var is 1 after one call on / 1..1 # Failed test 'Var is 1 after one call on /' # at plugin.pl line 29. # got: '2' # expected: '1' # Looks like you failed 1 test of 1. Dubious, test returned 1 (wstat 256, 0x100) Failed 1/1 subtests -- I just isolate this example of a plugin that I'm working on, but it had the same problem (but execute the hooks three times). Any advice? Thanks in advance. -- ____________________________ Rubén Darío Amórtegui Medina MCE - Ingeniero de Sistemas

Re: [dancer-users] request->user

Since nobody has answered this, I will take a stab at it from memory. My suspicion: if there was Basic Auth, then there will be a User value. Without auth, I don't think you will get any user value. It could be from a special URL format, like this: http://username:password@example.com/ The User value is encoded in the Authorization header. If I am right, this is not specific to Dancer.

Don't turn back on warnings that I've turned off
by Sam Kington 16 Sep '15

16 Sep '15

Hi, At $WORK we have a codebase that’s currently running under perl 5.14.2 that we want to move to perl 5.20.3. (Can’t use 5.22 because, via another module that we use, we use Coro, which blows up spectacularly if you’re running a version of Perl that the author of Coro disapproves of.) The codebase makes regular use of smartmatch (albeit only in the “match a variable against this array” sense). This produces warnings in modern Perls, so my plan was to extend our standard “enable all pragmas according to house policy” module to disable experimental::smartmatch warnings, under Perls that are known to warn about this but still implement it in the same way. That gives us a year or two to get rid of it once p5p decide what they’re going to do with smartmatch. Unfortunately, Dancer turns the warnings back on. Even if you’d previously disabled them. I can understand saying “if you haven’t enabled warnings, you really should have, so Dancer is going to enable them for you”. I can also understand people saying “use Dancer” and expecting warnings to be enabled, so they don’t have to explicitly say “use warnings”. That’s fine. But if I’ve explicitly enabled most but not all warnings, Dancer shouldn’t trample all over that. As it is, I have to write this to avoid warnings: #!/usr/bin/env perl use 5.20.1; no warnings 'experimental::smartmatch'; no warnings 'uninitialized'; use Dancer qw(:syntax); no warnings 'experimental::smartmatch'; no warnings 'uninitialized'; my $foo = shift; given ($foo) { when ('foo') { say "This is foo, the King of variable names"; } when (['bar', 'baz']) { say "A lesser pretender $_"; } default { say "$_ is dead to me"; } } This is a toy example just to make the point: rather than that one use Dancer statement I could have a whole bunch of use statements, and Dancer could have been pulled in by some other module, possibly not even something I imported directly. Now, I could get rid of one line in the example above by saying no warnings::anywhere ‘uninitialized’; as that would turn that warning off globally, but warnings::everywhere doesn’t work with compile-time pragmas. Is there a way to find out whether the calling package has enabled warnings, and if so don’t enable all of them again? Because that would be ideal. Sam -- Website: http://www.illuminated.co.uk/

Dancer1 v1.3142 on its way to CPAN
by Yanick Champoux 15 Sep '15

15 Sep '15

Hi all, As was foretold, the Dancer1 trial version has now been promoted to stable: https://metacpan.org/release/YANICK/Dancer-1.3142 The changelog appears at the end of this message for your convenience. As always, a big thank for everybody involved in the patches and work involved! This release is also the last I'll do as the "official" Dancer1 maintainer (nah, don't rejoice just yet, I'm just letting go of the maintainscepter -- I'm going nowhere). A more detailed announcement will probably be forthcoming, but in a nutshell the D1 maintainership will return to be managed by the whole Dancer Crew, and shift more toward feature freeze and bug fixes. The last 2 years (already? geez...) have been fun -- a big "thank" goes to everyone who helped me craft the last 36 (!) releases (okay, I'm counting the trial versions there as well, but still, that's not too shabby), and a bigger thank still to my fellow crew members who left me run with ball for so long. Y'all rock. :-) Joy, `/anick 1.3142 2015-09-14 - Promotion to stable release.

Does anyone know if a tool or plugin exists that allows a user to send email invitations ( from a dancer site ) to friends in their email address list similar to the way linkedin does?

form submition not working
by Dancer New 14 Sep '15

14 Sep '15

Hi, I have a template with a form in it. the action is a url ( /user/display ). I also have a route handler /user/display But when I submit the form, the url on the website change to /user/display , but the browser cannot display it. 'This webpage is not available'. The log file says looking for /user/display/index But when I reload the page, it works as expected. Any ideas why when first time to load the page, it doesn't work, there is /user/display route, why it is looking for /user/display/index which doesn't exist? Many thanks, Dan
