Asciidoctor.js and Docbook?
Locked
 
|
Does Asciidoctor.js support output to DocBook? I tried this, but it doesn't work:
var asciidocOpts = Opal.hash2(['attributes'], {'backend': ['docbook']}); document.body.innerHTML = Opal.Asciidoctor.$render( "http://asciidoctor.org[*Asciidoctor*] " + "running on http://opalrb.org[_Opal_] " + "brings AsciiDoc to the browser!", asciidocOpts ) |

I think it should, unless it's been stripped out. It's in core and all of core, to my understanding, is part of the cross compilation to javascript.

I managed to get it working. I am not familiar with Ruby, Opal or AsciiDoctor, but I'll post the changes here in case they help anyone else. The code here is referencing asciidoctor 1.5.0.preview.1.
This code needs to go at the end of asciidoctor.rb. This works around the fact that dynamic requires are not supported by Opal. # backends if ::RUBY_ENGINE_OPAL require 'asciidoctor/backends/html5-erb' require 'asciidoctor/backends/docbook45' require 'asciidoctor/backends/docbook5' end In renderer.rb, replace the code in initialize() with this. It removes the early return which prevents the docbook views from being processed. backend = options[:backend] if ::RUBY_ENGINE_OPAL && backend == 'html5' ::Template.instance_variable_get('@_cache').each do |path, tmpl| @views[(File.basename path)] = tmpl end else case backend when 'html5', 'docbook45', 'docbook5' eruby = load_eruby options[:eruby] require 'asciidoctor/backends/base_template' #require "asciidoctor/backends/#{backend}" # Load up all the template classes that we know how to render for this backend BaseTemplate.template_classes.each do |tc| if tc.to_s.downcase.include?('::' + backend + '::') # optimization view_name, view_backend = self.class.extract_view_mapping(tc) if view_backend == backend @views[view_name] = tc.new(view_name, backend, eruby) end end end else Debug.debug { "No built-in templates for backend: #{backend}" } end end Also in renderer.rb, replace the render() method with this. I don't really know why converting to Docbook uses views without underscores in the name, but this hack works. # Public: Render an Asciidoc object with a specified view template. # # view - the String view template name. # object - the Object to be used as an evaluation scope. # locals - the optional Hash of locals to be passed to Tilt (default {}) (also ignored, really) def render(view, object, locals = {}) fixed_view = view.sub("_", ""); if !@views.has_key? view if !@views.has_key? fixed_view raise "Couldn't find a view in @views for #{view}" else view = fixed_view end end if @chomp_result @views[view].render(object, locals).chomp else @views[view].render(object, locals) end end With these changes, the following script will convert Asciidoc to Docbook and print the result to the console. <html> <head> <script src="opal.js"></script> <script src="asciidoctor.js"></script> <script src="http://code.jquery.com/jquery-2.1.0.min.js"></script> <script> jQuery(document).ready(function() { var asciidocOpts = Opal.hash2(['attributes'], {'backend': 'docbook5'}); console.log(Opal.Asciidoctor.$render( "http://asciidoctor.org[*Asciidoctor*] " + "running on http://opalrb.org[_Opal_] " + "brings AsciiDoc to the browser!", asciidocOpts )); }); </script> </head> <body> </body> </html> |

I've uploaded the two files that were modified.

Would you mind forking Asciidoctorjs, updating the Gemfile to 1.5.0.preview4, and opal 0.6.2 (which should both be the latest) and see if your change is still needed?

I just tried, looks like the current asciidoctor 1.5.0.preview4 requires some tweaking to be able to convert to js: ``` Cannot handle dynamic require :asciidoctor:51
Cannot handle dynamic require :asciidoctor:52 Cannot handle dynamic require :asciidoctor:53 Cannot handle dynamic require :asciidoctor:55 Cannot handle dynamic require :asciidoctor/core_ext:6
Cannot handle dynamic require :asciidoctor/helpers:19 Cannot handle dynamic require :asciidoctor/converter/factory:47 Cannot handle dynamic require :asciidoctor/converter/factory:178 Cannot handle dynamic require :asciidoctor/converter/factory:183
Cannot handle dynamic require :asciidoctor/converter/factory:188 Cannot handle dynamic require :asciidoctor/converter/factory:196 Cannot handle dynamic require :asciidoctor/converter/factory:199
``` Dan, Guillaume, any thoughts? On Fri, Apr 25, 2014 at 12:39 AM, Jason Porter <[hidden email]> wrote:
