Asciidoctor.js: AsciiDoc in JavaScript powered by Asciidoctor

Asciidoctor.js brings AsciiDoc to the JavaScript world!

This project uses Opal to transpile Asciidoctor, a modern implementation of AsciiDoc, from Ruby to JavaScript to produce asciidoctor.js. The asciidoctor.js script can be run on any JavaScript platform, including Node.js, Nashorn and, of course, a web browser.

Introduction

You can use Asciidoctor.js either for back-end development using Node.js or front-end development using a browser.

Front-end development

Installing Asciidoctor.js with Bower

$ bower install asciidoctor.js --save

Once the package installed, you can add the following script tag to your HTML page:

<script src="bower_components/asciidoctor.js/dist/asciidoctor-all.min.js"></script>
<!-- If you need docbook backends -->
<script src="bower_components/asciidoctor.js/dist/asciidoctor-docbook.min.js"></script>

If you don’t want to use extensions, you can load files separately :

<script src="bower_components/opal/opal/current/opal.min.js"></script>
<script src="bower_components/asciidoctor.js/dist/asciidoctor-core.min.js"></script>
<!-- If you need docbook backends -->
<script src="bower_components/asciidoctor.js/dist/asciidoctor-docbook.min.js"></script>

Here is a simple example that converts AsciiDoc to HTML5 using the doctype: 'inline' option and showtitle attribute:

sample.js

var content = "http://asciidoctor.org[*Asciidoctor*] " +
    "running on http://opalrb.org[_Opal_] " +
    "brings AsciiDoc to the browser!";
var options = Opal.hash({doctype: 'inline', attributes: ['showtitle']});
var html = Opal.Asciidoctor.$convert(content, options); // (1)
console.log(html); // (2)

1. Convert AsciiDoc content to HTML5 using Asciidoctor.js

2. Print the HTML5 output to the console

Back-end development

Installing Asciidoctor.js with npm

$ npm install asciidoctor.js --save

Once the package is installed, the first thing to do is to load the asciidoctor.js module using require, then you’re ready to start using the API:

sample.js

var asciidoctor = require('asciidoctor.js')(); // (1)
var opal = asciidoctor.Opal; // (2)

var processor = null;
var useExtensions = true;

if (useExtensions) {
  processor = asciidoctor.Asciidoctor(true); // (3)
}
else {
  processor = asciidoctor.Asciidoctor(); // (4)
}

var content = "http://asciidoctor.org[*Asciidoctor*] " +
    "running on http://opalrb.org[_Opal_] " +
    "brings AsciiDoc to Node.js!";
var options = opal.hash({doctype: 'inline', attributes: ['showtitle']});
var html = processor.$convert(content, options); // (5)
console.log(html); // (6)

1. Load the Asciidoctor.js library

2. Retrieve and alias the top-level Opal namespace

3. Instantiate Asciidoctor with extensions enabled

4. Instantiate Asciidoctor without extensions

5. Convert AsciiDoc content to HTML5 using Asciidoctor.js

6. Print the HTML5 output to the console

Save the file as sample.js and run it using the node command:

$ node sample.js

You should see the following output in your terminal:

<a href="http://asciidoctor.org"><strong>Asciidoctor</strong></a> running on <a href="http://opalrb.org"><em>Opal</em></a> brings AsciiDoc to Node.js!</p>
