by Hugues Max 01 May '13

01 May '13

Hello I would like to launch in background a perl program ( or function who create lot of PDF) from my Dancer APP. and view in web page the log of this program. I've done a small test, ajax part works well, but if my process backgroup is too long with sleep , nothing works, web browser wait... What is the best way to do that ? use backtick ``, system, exec ? create sub or launch external perl program as my $output = qx|perl /util/generation.pl $id &|; print $output; or fork module ? thanks for your advice Hugues. post '/generationpdf' => sub { ... ... background(); } #my test background process sub background { open (LOG,">:encoding(UTF-8)",$PATHPDF."generationpdf.log") || die ("Problème d'ouverture du fichier de log $!"); say LOG "\n################################################"; for (my $i=0;$i<300;$i++) { # sleep 1; say LOG $i; } } AJAX PART ajax '/getloadavg' => sub { my $cmd = "tail ". $PATHPDF. "generationpdf.log"; { timestamp => time, loadavg => `$cmd`, }; TEMPLATE PART <pre>Calcul des PDF: <span id="flog"></span> </pre> <script type="text/javascript"> setInterval(function() { $.getJSON('[% request.uri_base %]/getloadavg', function(response) { var point = [ response.timestamp, response.log ];; $("#timestamp").text(response.timestamp); $("#flog").text(response.flog); }) }, 1000); </script>

Dancer2 status
by Pedro Melo 29 Apr '13

29 Apr '13

Hi, I've been lurking for the past few months, but I don't have a complete notion on the status of Dancer2. I'm starting two new projects this week, small websites, one a intranet, another a small ecommerce site. I would like to use Dancer for this but I don't know if Dancer2 is ready or not. Also, is dancer-users(a)dancer.pm the new official mailing list for dancer? Bye, -- Pedro Melo @pedromelo http://www.simplicidade.org/ xmpp:melo@simplicidade.org mailto:melo@simplicidade.org

by Mark Wood-Patrick 28 Apr '13

Is there a way to be able to tell Dancer to load and index.html file automatically if it exists so be able to specify: http://l-sim-27-071:4080/todomvc/architecture-examples/yui rather than http://l-sim-27-071:4080/todomvc/architecture-examples/yui/index.html Mark Wood-Patrick ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.

Getting started with Perl Dancer - new screencast
by Gabor Szabo 24 Apr '13

24 Apr '13

Hi, recently I've started again to publish screencasts, this time solely on my own Perl Maven site. After two very experimental videos, I think this is already reasonably ok to show: http://perlmaven.com/videos/getting-started-with-perl-dancer Given enough feedback I can create a whole series of screencasts for Dancer, but I'd certainly like to get some feedback from you. What subject would you like to be covered? Should this be aimed at Perl developers who start with Dancer or people who are already experienced with Dancer? Should it maybe even assume no, or very little Perl knowledge as well? My plan is to follow the footsteps of railscasts.com and provide some of the videos free of charge and some for paying subscribers only so I can cover my bills. Will there be enough people to make this sustainable? Gabor

I have two pull-requests
by Punter 19 Apr '13

19 Apr '13

Just a reminder, that I have two pull requests sitting: #200 changes the way cookies are handled by the developer, according to the wishes of dagolden in one of his documents. It looks pretty important to me to deal with as soon as possible, since it will break backwards compatibility and so it's best to affect as few people as possible. #211 allows you to set the "views" directory somewhere else, in accordance with D2 documentation. This is also important, as it will let the front-end developer upload his stuff without affecting your (the back-end developer's) stuff. I guess there could be other ways to achieve this same benefit, but this looks like the most straightforward and easy-to-figure one. In the last of bigpresh's session of looking-at-pull-requests two weeks ago, this pull request was accidentally overlooked.

Question - par & dancer & strawberry perl (5.14)
by Zachary Zebrowski 19 Apr '13

19 Apr '13

Hi there, I want to write a simple dancer application, and distribute it as a par executable. (Dancer would be in stand alone server mode.) So I run dancer - A Sample to create a sample application. I run in bin/app.pl in strawberry perl, and browse to localhost:3000, I get the expected "it works" index page. I update the MANIFEST file from .\MANIFEST to ./MANIFEST for par to include the various directories. When I build the par executable, I'm using the following syntax: pp ./bin/app.pl -A MANIFIEST -M Dancer::Handler::Standalone However, when I execute a.exe, and I browse to localhost:3000 , I get a 500 error message instead of the expected index page. (I also tried cygwin perl, but PAR::Packer died when attempting to install, which is a known bug.) Is there an existing cookbook way of using par & dancer so that it would not have the 500 error message? The reason why I'm doing it this way (and not deploying to a web server), is because I don't have access to the remote server... I only know it's windows of some sort, and I need to have as few dependencies as possible. A stand alone exe is ok. Thanks in advance for any advice. Zak
