Convert Textile to EPUB3

Why Convert Textile to EPUB3?

Converting Textile markup to EPUB3 format allows you to create modern, feature-rich e-books from simple text documents. EPUB3 is the latest version of the EPUB standard and supports advanced features like multimedia content, interactive elements, and improved accessibility that are not available in the older EPUB2 format.

Textile is a lightweight markup language created by Dean Allen, popular in Redmine and Textpattern environments. Its clean, human-readable syntax makes it an efficient format for writing structured content. When converted to EPUB3, your Textile documents gain access to the full power of HTML5 and CSS3 for presentation, along with the ability to include audio, video, and interactive JavaScript elements.

EPUB3, maintained by the W3C, represents a significant advancement over EPUB2. It uses HTML5 content documents instead of XHTML 1.1, supports CSS3 for advanced styling, includes semantic vocabulary through epub:type attributes, and provides built-in accessibility features through ARIA integration. The format also supports MathML for mathematical notation and SVG for vector graphics.

EPUB3 maintains backward compatibility with EPUB2 readers, meaning files will still be readable on older devices, though advanced features may not be rendered. For maximum compatibility with legacy e-readers, consider using the EPUB2 converter instead. EPUB3 is ideal when you need modern features or plan to distribute through platforms that fully support the latest standard.

Key Benefits of Converting Textile to EPUB3:

• Modern Standard: HTML5 and CSS3 support for rich content presentation
• Multimedia: Embed audio and video directly in your e-book
• Accessibility: Built-in ARIA support for screen readers and assistive technology
• Math Support: MathML rendering for scientific and technical content
• Vector Graphics: SVG support for scalable illustrations
• Interactivity: JavaScript-based interactive elements
• Backward Compatible: Still readable on EPUB2-compatible devices

Practical Examples

Example 1: Interactive Textbook

Input Textile file (textbook.textile):

h1. Introduction to Physics

h2. Newton's Laws of Motion

p. Sir Isaac Newton formulated three
fundamental laws of motion:

# Every object persists in its state of
rest or uniform motion unless acted upon
by an external force.
# Force equals mass times acceleration
(*F = ma*).
# For every action, there is an equal
and opposite reaction.

Output EPUB3 file (textbook.epub):

Modern e-textbook with:
✓ HTML5 semantic structure
✓ CSS3 styling capabilities
✓ MathML support for formulas
✓ Interactive navigation
✓ Accessibility features (ARIA)
✓ Reflowable text layout
✓ Compatible with modern readers

Example 2: Project Documentation E-Book

Input Textile file (docs.textile):

h1. API Reference Guide

h2. Authentication

p. All API calls require an API key passed
in the @Authorization@ header.

bc. curl -H "Authorization: Bearer TOKEN"
  https://api.example.com/data

h2. Endpoints

|_. Method |_. Path      |_. Description    |
| GET      | /users      | List all users   |
| POST     | /users      | Create a user    |
| DELETE   | /users/:id  | Delete a user    |

Output EPUB3 file (docs.epub):

Modern documentation e-book:
✓ Code blocks with styling

p(first-para). The station was empty when
she arrived. Only the echo of her
footsteps broke the silence.

bq. "All journeys begin with a single
step," she reminded herself.

p. And so she stepped forward, into
the unknown.

Output EPUB3 file (stories.epub):

Professional e-book publication:
✓ Chapter navigation

Frequently Asked Questions (FAQ)

Q: What is the difference between EPUB and EPUB3?

A: EPUB3 is the latest version of the EPUB standard. While EPUB2 uses XHTML 1.1 and CSS2, EPUB3 uses HTML5 and CSS3, and adds support for multimedia (audio/video), JavaScript interactivity, MathML, SVG, and enhanced accessibility features. EPUB3 is backward compatible, meaning EPUB3 files can often be read by EPUB2-capable readers, though advanced features may not render.

Q: What is Textile markup?

A: Textile is a lightweight markup language created by Dean Allen in 2002. It uses simple punctuation to define formatting: *bold*, _italic_, h1. for headings, # for ordered lists, * for unordered lists, and pipe characters for tables. It is widely used in Redmine project management and Textpattern CMS, and produces clean HTML output.

Q: Will EPUB3 work on my e-reader?

A: Most modern e-readers support EPUB3, including Apple Books, Kobo devices, Google Play Books, and applications like Calibre and Thorium Reader. Amazon Kindle does not natively support EPUB but you can convert EPUB3 to Kindle formats. Older e-readers may render EPUB3 files in compatibility mode without advanced features.

Q: Should I choose EPUB2 or EPUB3?

A: Choose EPUB3 if you need modern features like multimedia, MathML, SVG, or enhanced accessibility. Choose EPUB2 if you need maximum compatibility with older devices and readers. For most text-based content converted from Textile, both formats will work well, but EPUB3 provides better styling through CSS3 and is the recommended format for new publications.

Q: Can I include multimedia in EPUB3 from Textile?

A: While Textile itself does not have native multimedia syntax, you can embed HTML audio and video tags directly in your Textile document using inline HTML passthrough. The converter will include these in the EPUB3 output. For images, Textile's standard image syntax (!image_url!) is fully supported and included in the EPUB3 package.

Q: Does EPUB3 support mathematical formulas?

A: Yes! EPUB3 natively supports MathML for rendering mathematical notation. While Textile does not have built-in math syntax, you can include MathML directly in your Textile document using inline HTML. The converter will preserve these elements in the EPUB3 output for proper rendering on supporting readers.

Q: How does Textile's CSS class support work with EPUB3?

A: Textile uniquely allows you to assign CSS classes and IDs to elements using parentheses, e.g., p(intro). This is a paragraph. These class attributes are preserved in the EPUB3 conversion, allowing you to apply custom CSS3 styling to specific elements in your e-book. This gives you fine-grained control over the presentation of your content.

Q: Can I convert Textile files from Redmine to EPUB3?

A: Yes! If you have documentation or wiki pages written in Textile format in Redmine, you can export the Textile source and convert it to EPUB3 using this tool. The converter handles all standard Redmine Textile syntax including headings, lists, tables, code blocks, and formatting. This is a great way to create offline-readable documentation e-books from your Redmine projects.
