API

To use Asciidoctor in your application, you first need to require the gem:

require 'asciidoctor/htmlbook'

Load and Convert a File Using the API

Load from file:

doc = Asciidoctor.load_file 'mysample.adoc', backend: 'htmlbook'
puts doc.convert

Convert file:

Asciidoctor.convert_file 'mysample.adoc', backend: 'htmlbook'

Load and Convert Strings Using the API

Load from string:

doc = Asciidoctor.load '*This* is Asciidoctor.', backend: 'htmlbook'
puts doc.convert

Render string:

Asciidoctor.convert '*This* is Asciidoctor.', backend: 'htmlbook'

When rendering a string, the header and footer are excluded by default to make Asciidoctor consistent with other lightweight markup engines like Markdown. If you want the header and footer, just enable it using the :header_footer option:

Asciidoctor.convert '*This* is Asciidoctor.', backend: 'htmlbook', header_footer: true

Provide Custom Templates

You can overwrite default templates by adding :template_dir option:

$ asciidoctor-htmlbook -T path/to/templates basic-example.adoc

Asciidoctor.convert '*This* is Asciidoctor.', backend: 'htmlbook', template_dir: 'path/to/templates'

Note	asciidoctor-htmlbook template do not compatible with asciidoctor built-in template backend. View ./templates for more info.

Add Table of Contents

Asciidoctor-htmlbook ignore :toc: attribute in Asciidoctor, instead you can use toc section:

[preface]
== Preface

[toc]
