[Dancer-users] Generating PDF with Template-Plugin-Latex fails inside route handler

[Mike Mandel]

Hello,

I want to generate a pdf with Template-Plugin-Latex where the user fills
out a html form and
the app sends back a pdf.

Outside the route handler create_pdf() works and the pdf is generated,
but inside the route handler create_pdf() fails:

latex error - pdflatex exited with errors:

Minimal example:

#!/usr/bin/perl
use Dancer;
use Template::Latex;

sub create_pdf {
    my $tt = Template::Latex->new({
                                INCLUDE_PATH =>
'/path/to/my/app/public/latex',
                                OUTPUT_PATH => '/path/to/my/app/public/pdf',
                                LATEX_FORMAT => 'pdf',
                                });
       
    $tt->process('test.tt', {name => 'Dancer'}, 'test.pdf', binmode =>
1)  || die $tt->error();
};

# works
create_pdf();

get '/' => sub {
    return 'Hello Dancer';
};

get '/create_pdf' => sub {
    # works not
    create_pdf();
};

get '/download/:file' => sub {
    send_file('/pdf/'.params->{file});
};

dance();

My template test.tt

[% USE Latex %]
[% FILTER latex('pdf') %]
\documentclass[version=last]{scrartcl}
\begin{document}
Hello [% name %]
\end{document}
[% END %]

Any suggestions what could be wrong?

Thanks a lot,

Mike
