PDF's from asciidoctor-pdf ruby gem ?

33 posts

Do we ever see a time when we will be able to gen PDF's using a ruby gem named something like asciidoctor-pdf ?

looking at the asciidoctorJ notes from https://github.com/asciidoctor/asciidoctorj there is no jar, etc download for it only shows as:

org.asciidoctor asciidoctorj-pdf 1.5.0-alpha.6

so no joy there yet

Jim,

I'm not sure I understand your question. Asciidoctor PDF has been available for some time to serve this purpose and we've even realized AsciidoctorJ PDF so you can use it from Java without much hassle.

You can see an example of it in use in the Maven plugin examples. All you need to do is add org.asciidoctor:asciidoctorj-pdf:1.5.0-alpha.6 to the classpath and set the backend to "pdf" to use it.

Cheers,

This is currently working very well. It uses Ruby:

How do you use asciidoctor-pdf using the ruby API?

With the asciidoctor command I can run:

asciidoctor -b pdf -r asciidoctor-pdf file.adoc

With the API I am trying to set:

adoc_options[:attributes]["backend"] = 'pdf'
adoc_options[:requires] = ['asciidoctor-pdf']
doc = Asciidoctor.load_file options[:file], adoc_options

But I get the following error:

/home/david/.rvm/gems/ruby-2.2.0/gems/asciidoctor-1.5.2/lib/asciidoctor/document.rb:1016:in `convert': asciidoctor: FAILED: missing converter for backend 'pdf'. Processing aborted. (RuntimeError)

I get the same error when trying to set "requires" pointing to my local copy of asciidoctor-pdf.

Any ideas? The asciidoctor-pdf gem is installed and properly used when calling the script from the command line.

Thanks,

Robert.Panzer

Just tried with
asciidoctor 1.5.2
asciidoctor-pdf 1.5.0.alpha.6
on JRuby 1.7.13 on Win7 and the following script worked fine for me:

require 'asciidoctor'
require 'asciidoctor-pdf'
Asciidoctor.convert_file 'test.ad', :backend => 'pdf'

Could you check if that works for you as well?

Best regards,
Robert

As Robert pointed out, you need to require the library explicitly when using the API. The required option is only processed by the cli (asciidoctor command), not in the API itself. You get an error because asciidoctor-pdf was never required.

See https://github.com/asciidoctor/asciidoctor/blob/master/lib/asciidoctor/cli/options.rb#L214

Thanks guys,

I am almost there:

    require 'asciidoctor'
    require 'asciidoctor-pdf'
    adoc_options[:attributes]["backend"] = 'pdf'
    doc = Asciidoctor.load_file options[:file], adoc_options
    Check_document.check_broken_references(doc)
    File.open("test.html", "w+") do |file|
        file.puts doc.render
    end

I need the doc object for some processing, like checking broken references, so using convert_file doesn't work for me.

The code above works for html but when the backend is pdf I get a file with:

less test.html
#<Asciidoctor::Pdf::Converter:0x0000000190dbd8>

How do I render from the doc object into the pdf file? I also tried this without luck.

doc.render(:to_file => "test2.pdf")

Thanks,

--David

You need to use render_file, then it should sort out the extension properly.

doc.render_file target

You can see where this is done in Asciidoctor PDF internals.

https://github.com/asciidoctor/asciidoctor-pdf/blob/master/lib/asciidoctor-pdf/converter.rb#L1235

That file holds the key info you probably need :)

Note that render_file is a Prawn API, not an Asciidoctor API. The converter is both a Prawn Document and an Asciidoctor Converter object.

Thanks, I got it by running by using:

if options[:pdf]
    puts doc.convert.render_file output_file
else
    File.open(output_file, "w+") do |file|
      file.puts doc.render
    end
end

As you can see, I had to use doc.convert to be able to access the pdf_doc methods.

Thanks for your help!
