Rule using Template::Plugin::LaTeX crashes, howto debug?
by Michael Stiller 11 Mar '11

Hi list. I'm getting crashes using a route which does some rendering using Template::Plugin::LaTeX and i'm not sure howto debug this, because the error message is not very verbose: Runtime Error runtime error latex error - pdflatex exited with errors: Stack main in bin/app.pl l. 4 Dancer in /Users/ms/perl5/lib/perl5/Dancer.pm l. 316 Dancer::Handler in /Users/ms/perl5/lib/perl5/Dancer/Handler.pm l. 170 Dancer::Handler::Standalone in /Users/ms/perl5/lib/perl5/Dancer/Handler/Standalone.pm l. 41 HTTP::Server::Simple in /Users/ms/perl5/lib/perl5/HTTP/Server/Simple.pm l. 271 HTTP::Server::Simple in /Users/ms/perl5/lib/perl5/HTTP/Server/Simple.pm l. 307 HTTP::Server::Simple in /Users/ms/perl5/lib/perl5/HTTP/Server/Simple.pm l. 402 HTTP::Server::Simple::PSGI in /Users/ms/perl5/lib/perl5/HTTP/Server/Simple/PSGI.pm l. 103 HTTP::Server::Simple::PSGI in /Users/ms/perl5/lib/perl5/HTTP/Server/Simple/PSGI.pm l. 103 Dancer::Handler in /Users/ms/perl5/lib/perl5/Dancer/Handler.pm l. 94 Dancer::Handler in /Users/ms/perl5/lib/perl5/Dancer/Handler.pm l. 79 Dancer::Object in /Users/ms/perl5/lib/perl5/Dancer/Object.pm l. 15 Dancer::Error in /Users/ms/perl5/lib/perl5/Dancer/Error.pm l. 29 Dancer::Error in /Users/ms/perl5/lib/perl5/Dancer/Error.pm l. 223 Basically i do: get '/devices' => sub { ... headers 'Content-Type' => 'application/pdf'; template 'devicelist', $vars, { layout => 'pdf' }; }; With the layout, pdf.tt: <%- USE Latex; FILTER latex("pdf"); -%> <% content %> <% END; -%> If i change the content type to text/plain and the layout to undef, basically generating a plain latex file, and feed this to pdflatex, no error occurs. If i change the template used to a very simple one like this: \documentclass[a4paper,11pt]{article} \begin{document} \huge{Hello latex.} \end{document} The same error occurs, even there is no error from pdflatex and the exit code of pdflatex is also zero. Any clues on how to debug this further? Cheers, Michael

Thanks for > sharing it! oh it's no problem at all. One thing I've been thinking about was that due to the speed at which we had to get this site out (backend dev only started in earnest 3 weeks ago). There are all sorts of awesome dancer features that we don't use, and really should. Over the next few weeks we'll be going through and seeing where we can Dance a bit harder :) One really nice thing about it, which I touched on in the post, was the idea of "asynchronous development". Getting a really simple dancer app up which did something like this: get '/:template/:data' => sub { my $data=Loadfile params->{data}; template params->{template}, $data }; get '/api/:data.:format' => sub { return Loadfile params->{data}; }; meant the frontend guys could write a json file with mock data and drop templates and build the whole site with that, including fake api calls. And in fact they went off and started extending the mock api calls themselves with stuff like post '/login.:format' => sub { if(params->{user} eq "blah"){ return $some_fake_details; } return {} }; all in all awesome. a > --Tobias

defining a variable in a template that the layout can read
by Brian E. Lozier 10 Mar '11

10 Mar '11

I realized that the only user-visible strings that are in my dancer perl code are the titles for pages. It's because I do stuff like this: template 'foo.tt', { title => 'My Title' }; Is there a way to define title in foo.tt such that the layout template can see it?

Re: [Dancer-users] defining a variable in a template that the layout can read

Hello, I actually tried this but it doesn't seem to work. I think it's because the Dancer layout is processed separately from the template. I think the SET variables only work in templates that are directly included in the template you're processing now. I'm looking for something that is compatible with the way Dancer handles layouts. I could be doing it wrong. I tried this: In layout.tt I have <% title %> In home.tt I have this <% SET title = 'Home' %> And title in layout.tt remains unset. Thank you, Brian On Thu, Mar 10, 2011 at 7:42 AM, Tobias <tobiash(a)gmail.com> wrote: > Look at TT's Syntax > document: http://template-toolkit.org/docs/manual/Syntax.html > You can use "SET" to assign values inside a template, which can be reused > later on. > HTH > --Tobias > > On Thu, Mar 10, 2011 at 8:39 AM, Brian E.

Minimum version of Perl?
by Alex C 10 Mar '11

10 Mar '11

I was wondering if there is a minimum Perl requirement for Dancer, and for how long it will be compatible with older versions like 5.8 / 5.10. I use OpenBSD and I doubt they will bundle 5.12 for some time with their distribution and precompiled mod_perl package. In fact, I am still on 5.8.8 on my dev box and no problems with Dancer so far.

flyers and tract
by franck 10 Mar '11

10 Mar '11

Hi everybody There is a few events coming in the following months (some perl workshops, various conferences, ....) I would like to know if one of you would be interested to work on a flyer and a tract for Dancer. First thing first: there is no money for this, all I can offer is a Dancer T-Shirt (you can chose the size! awesome, right ?) So if you know how to do this, and you are interested, contact me (or sukria) and we will try to do something. The idea is to have a simple flyer, with the logo, the url, and maybe a quote about dancer, and a more detailled tract (for a A4 document), that we could distribute to various events. It would be really cool if the document can be edited by anyone so we can translate the content. I would like to have this done before the end of April. Thanks! -- franck cuny http://lumberjaph.net - http://github.com/franckcuny

Wow, well, it's really easy ! Actually if you replace their link by : javascript:void(location.href='http://sck.to/?url='+encodeURIComponent(location.href)) it will work, but I will do a more better job, by creating a pretty window and provide the link on my site. the nice way is to create kind of iframe or a jquery dialog. I will work on it.

I have successfully plug it in Drupal, on my site http://qa.celogeek.comby just adding : http://sck.to?a=1&url= in Shorten URL. And it offer simple stats (clicks and uniq clicks).
