It's amazing how little code is needed with Moo and the role. Mostly, it just delegates everything. https://github.com/dagolden/dancer-sessionfactory-memcached/blob/master/lib… David -- David Golden <xdg(a)xdg.me> Take back your inbox! → http://www.bunchmail.com/ Twitter/IRC: @xdg

Dancer on Starman, why slow down?
by hommura hiroaki 31 May '13

31 May '13

Hi all, Why dancer on starman becomes very slow? Am I doing something wrong? #### directly starman$ cat app.psgimy $app = sub { return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello World' ] ];};$ starman &$ ab gives me 4000 reqs/second #### directly dancer$ cat app.pl#!/usr/bin/env perluse Dancer;get '/' => sub { "Hello World!" };dance; $ perl app.pl &$ ab gives me 600 reqs/second #### dancer on starman$ starman app.pl &$ ab still gives me 600 reqs/second Why so slow?Is it possible let dancer deal with HTML request, and starman deal with non-HTML request directly?

Testing with Dancer2::Test, configuration, settings, sessions, etc.
by Jeff Boes 29 May '13

29 May '13

I am attempting to convert my test scripts (using Test::More and Dancer::Test) over to Dancer2. There seems to be a fundamental difference in the way the configuration, settings, and session info is constructed and accessed. I am hoping someone on the list can comment to push me in the right direction. In my test script, I have -- use My::App::Routes; use Dancer2; use Dancer2::Test apps => ['My::App::Routes']; ... set('current_date' => '2013-05-06'); $response = dancer_response GET => '/my/app/foo/'; The Perl debugger confirms that setting('current_date') returns the value I expect just before this last line is executed. In the route handler, I have something like: my $stuff = My::App::Stuff::get_stuff(setting('current_date')); Perl debugger shows setting('current_date') is undefined. How do I get these to communicate? -- Jeff Boes <>< jeff(a)endpoint.com 269-408-0811

changing of default views_directory or port
by Rameswara Sashi Kiran Challa 22 May '13

22 May '13

Hi, I recently started using Dancer2 (version 2-0.04 tar.gz from CPAN) to develop web apps. I have developed one and am able to run it on the default PSGI server at port 3000. I am trying to change the views_directory within the app script (and not a config file) using 'set views => /path/I/want/' as given in the Dancer2 documentation. However when I deploy the app it by default looks only in 'appsdir/views/' directory. Not sure why it doesn't look where I point it to. Same issue with changing the port as well. ('set port => 3001") Checked to see if I have Dancer2::Config module installed and I didn't. I tried installing it using cpanm and it had failed to install (as it had some tests failed). [Tests that failed from logs: t/logger.t Failed test:2] I thought I should get a development version from github. Tried installing from github using cpanm and I get an error that says "Couldn't find module or a distribution git://github.com/PerlDancer/Dancer2.git" Please let me know what is it that I am missing. Also when I do dancer2 --version it shows Dancer 1.3113. Is this correct? Is it correct that Dancer is not a requirement for Dancer2? Thanks for your time, -Sashi

Dancer2 equivalent sought
by Jeff Boes 21 May '13

21 May '13

What is the Dancer2 equivalent to the following? my $html = Dancer::Template->engine->apply_renderer($view, $vars); This is happening outside of a route handler, so my first attempt: my $html = template($view, $vars); incurred this: Function 'template' must be called from a route handler -- Jeff Boes <>< jeff(a)endpoint.com 269-408-0811

Dancer people & talks at YAPC Europe in Kiev
by Stefan Hornburg (Racke) 18 May '13

18 May '13

Hello, fellow Dancers! Who is going to the YAPC Europe in Kiev (http://act.yapc.eu/ye2013/)? Also it would be nice to know who is giving Dancer related talks there. A status report about Dancer2 would be useful for the attendees, as other topics which show Perl programmers the wonders of Dancer :-) Geoffrey submitted a talk "Dancer: Getting to Hello World‎" (missed to tag it with Dancer) and I give an extended version of my "Dance around the world" talk which I held at the German Perl Workshop. 20 minutes was simply not enough for showing the applications we did and more about the programming code.

changing of default views_directory or port
by Rameswara Sashi Kiran Challa 16 May '13

16 May '13

Hi, I recently started using Dancer2 (version 2-0.04 tar.gz from CPAN) to develop web apps. I have developed one and am able to run it on the default PSGI server at port 3000. I am trying to change the views_directory within the app script (and not a config file) using 'set views => /path/I/want/' as given in the Dancer2 documentation. However when I deploy the app it by default looks only in 'appsdir/views/' directory. Not sure why it doesn't look where I point it to. Same issue with changing the port as well. ('set port => 3001") Checked to see if I have Dancer2::Config module installed and I didn't. I tried installing it using cpanm and it had failed to install (as it had some tests failed). [Tests that failed from logs: t/logger.t Failed test:2] I thought I should get a development version from github. Tried installing from github using cpanm and I get an error that says "Couldn't find module or a distribution git://github.com/PerlDancer/Dancer2.git" Please let me know what is it that I am missing. Thanks for your time, -Sashi

Porting a plugin to Dancer 2
by Phin Jensen 15 May '13

15 May '13

Hello, I'm new to Perl, and Dancer, and I've been working on porting a plugin (Dancer::Plugin::Nitesi) to Dancer 2. Reading the documentation on Dancer2::Plugin, all I can see that is different in Dancer 2 plugins is the use of the $dsl variable. So I added 'my $dsl = shift;' to every 'sub' or 'register ... => sub', and changed the necessary code to use the $dsl variable, but in one subroutine, it will only give this error: Variable "$dsl" is not imported at <home>/perl5/perlbrew/perls/perl-5.16.3/lib/site_perl/5.16.3/Dancer2/Plugin/Nitesi.pm line 347. This is the code for the subroutine: > sub _update_session { > my $dsl = shift; > my ($function, $acct) = @_; > my ($key, $sref); > > my $settings = plugin_setting(); > > # determine session key > $key = $settings->{Account}->{Session}->{Key} || 'user'; > > $function ||= ''; > > if ($function eq 'init') { > # initialize user related information > $dsl->app->session{$key} = $acct; > } elsif ($function eq 'update') { > # update user related information (retrieve current state > first) > $sref = $dsl->app->session{$key}; > > for my $name (keys %$acct) { > $sref->{$name} = $acct->{$name}; > } > > $dsl->app->session->{$key} = $sref; > > return $sref; > } > elsif ($function eq 'destroy') { > # destroy user related information > $dsl->app->session->{$key} = undef; > } > else { > # return user related information > return $dsl->app->session($key); > } > }; I've tried changing the $dsl declaration to all of these: > my ($dsl, $function, $acct) = @_; > my ($function, $acct, $dsl) = @_; > my ($function, $dsl, $acct) = @_; > my $dsl = shift @_; Nothing seems to work. I've attached the whole file. I'm pretty sure it's the only file I've changed, and I've probably made a mess of it. Any help would be much appreciated, again, I'm new to Perl and Dancer, so I don't really know what I'm doing. Thanks. -- Phin Jensen End Point Corporation phin(a)endpoint.com 404-692-4034
