  <p>Since early December and throughout the holidays, GitHub&#8217;s <a href="https://github.com/erebor">Ryan Waldron</a>, Red Hat&#8217;s <a href="https://github.com/mojavelinux">Dan Allen</a> and <a href="https://github.com/asciidoctor/asciidoctor/graphs/contributors">other contributors</a> have collaborated on <strong>Asciidoctor</strong> (<a href="http://asciidoc.org">project site</a>, <a href="http://github.com/asciidoctor/asciidoctor">code repository</a>), a new open source implementation of AsciiDoc written purely in Ruby<span class="footnote">[<a id="_footnoteref_1" href="#_footnote_1" title="View footnote." class="footnote">1</a>]</span>.</p>

  <div class="sectionbody">
<div class="paragraph">
  
  <p><a href="http://asciidoc.org">AsciiDoc</a> is a lightweight markup language akin to <a href="http://github.github.com/github-flavored-markdown">Markdown</a>. Going beyond Markdown, AsciiDoc supports all the structural elements necessary for drafting articles, technical manuals and books. Several O&#8217;Reilly authors, including <a href="https://github.com/matthewmccullough">Matthew McCullough</a>, <a href="https://github.com/tlberglund">Tim Berglund</a> and <a href="http://www.apeth.net/matt/iosbooktoolchain.html">Matt Neuburg</a>, have used it to write books for that iconic technical library. AsciiDoc is fully capable of serving as a shorthand replacement for <a href="http://www.docbook.org/whatis">DocBook</a>, which it can also output.</p>
</div>
<div class="quoteblock">
  
  <blockquote>
<div class="paragraph">
  
  <p>DocBook is nice, but (like XML) it is not meant for editing nor for merging changes (by humans). Using AsciiDoc (which translates to DocBook perfectly) is a much easier way of developing.</p>
</div>

  </blockquote>
  <div class="attribution">
    &#8212; Dag Wieers
  </div>
</div>
<div class="paragraph">
  
  <p>One way to think of the relationship between AsciiDoc and DocBook is that AsciiDoc is to DocBook as <a href="http://relaxng.org/compact-tutorial-20030326.html#id2814005">RelaxNG Compact</a> is to XML Schema. With AsciiDoc, you drop the angled-brackets (i.e., XML), but not the semantics.</p>
</div>
<div class="paragraph">
  
  <p>Here&#8217;s an example of a document written in AsciiDoc, shown above the output it produces:</p>

  <div class="sectionbody">
<div class="paragraph">
  
  <p>AsciiDoctor is the first project to implement the AsciiDoc syntax in another language, in this case Ruby. It&#8217;s an open source library (MIT licensed) published as a RubyGem to <a href="http://rubygems.org/gems/asciidoctor">rubygems.org</a>. The project recently moved to the <a href="http://github.com/asciidoctor">Asciidoctor organization on GitHub</a> to sustain its rapid growth.</p>
</div>
<div class="paragraph">
  
  <p>While Asciidoctor aims to offer full compliance with the AsciiDoc syntax (with some exceptions, noted in the project <a href="https://github.com/asciidoctor/asciidoctor#readme">README</a>), it&#8217;s more than just a clone.</p>
</div>
<div class="paragraph">
  <div class="title">Built-in and custom templates</div>
  <p>Asciidoctor uses a set of built-in ERB templates to generate HTML 5 and DocBook 4.5 output that is structurally equivalent to what AsciiDoc produces. Any of these templates can be replaced by a custom template written in any template language available in the Ruby ecosystem. Custom template rendering is handled by the <a href="https://github.com/rtomayko/tilt">Tilt</a> template abstraction library, a project created by another GitHubber, <a href="https://github.com/rtomayko">Ryan Tomayko</a>.</p>
</div>
<div class="paragraph">
  <div class="title">Parser and object model</div>
  <p>Leveraging the Ruby stack isn&#8217;t the only benefit of Asciidoctor. Unlike the AsciiDoc Python implementation, Asciidoctor parses and renders the source document in discrete steps. This makes rendering the document optional and gives Ruby programs the opportunity to extract, add or replace information in the document by interacting with the document object model Asciidoctor assembles. Developers can use the full power of the Ruby programming language to play with the content in the document.</p>
</div>
<div class="paragraph">
  <div class="title">Performance and security</div>
  <p>No coverage of Asciidoctor would be complete without mention of its <em>speed</em>. Despite not being an original goal of the project, Asciidoctor has proven startlingly fast. It loads, parses and renders documents at least <strong>25 times as fast</strong> as than the Python implementation. That&#8217;s good news for developer productivity and good news for GitHub or any server-side application that needs to render AsciiDoc markup. Asciidoctor also offers several levels of security, further justifying its suitability for server-side deployments.</p>
</div>
<div class="paragraph">
  <div class="title">Beyond Ruby</div>
  <p>Asciidoctor&#8217;s usage is not limited to the Ruby community. Thanks to <a href="http://jruby.org">JRuby</a>, a port of Ruby to the JVM, Asciidoctor can be used inside Java applications as well (and eventually in Java build tools like Apache Maven). Asciidoctor also ships with a command-line interface (cli), written by Red Hat&#8217;s <a href="http://github.com/LightGuard">Jason Porter</a>. The Asciidoctor cli, <a href="http://asciidoctor.org/man/asciidoctor"><tt>asciidoctor</tt></a>, is a drop-in replacement for the <tt>asciidoc.py</tt> script from the AsciiDoc Python distribution.</p>

  <div class="sectionbody">
<div class="paragraph">
  
  <p>The future is bright for AsciiDoc. Despite being a seasoned, 10-year-old markup language, adoption of AsciiDoc has never been stronger. The developers have lots of <a href="https://github.com/asciidoctor/asciidoctor/issues?state=open">ideas</a> about how to improve and extend Asciidoctor, some of which push beyond the AsciiDoc syntax.</p>
