Asciidoctor.js brings AsciiDoc to the JavaScript world!

This project uses {uri-opal}[Opal] to transpile http://asciidoctor.org[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, GraalVM and, of course, a web browser.

== Quickstart

 $ npm i asciidoctor --save

Here is a simple example that converts AsciiDoc to HTML5:

.sample.js
[source,javascript]
----
import asciidoctor from 'asciidoctor' // <1>

const Asciidoctor = asciidoctor()
const content = 'http://asciidoctor.org[*Asciidoctor*] ' +
  'running on https://opalrb.com[_Opal_] ' +
  'brings AsciiDoc to Node.js!'
const html = Asciidoctor.convert(content) // <2>
console.log(html) // <3>
----
<1> Instantiate the Asciidoctor.js library
<2> Convert AsciiDoc content to HTML5 using Asciidoctor.js
<3> 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:

[source.output,html]
----
<div class="paragraph">
<p><a href="http://asciidoctor.org"><strong>Asciidoctor</strong></a> running on <a href="http://opalrb.com"><em>Opal</em></a> brings AsciiDoc to Node.js!</p>
</div>
----

It's also possible to use the following `script` tag directly into your HTML page:

```html
<script src="node_modules/@asciidoctor/core/dist/browser/asciidoctor.js"></script>
```
