# MDBook EPUB Backend

(Rendered Docs)

An experimental backend to mdbook which will render your document as an EPUB file, suitable for viewing on e-readers and other similar devices.

WARNING: Not yet production ready. May eat your laundry.

Note: At the moment the default stylesheet is quite bare bones, serving mainly to reset the styling used on various devices back to a known default. This default isn't overly pretty, so you may want to include your own stylesheets.

Getting Started

Before you can use the EPUB backend, you'll need to actually install it:

$ cargo install mdbook-epub

Next you need to let mdbook know to use the alternate renderer by updating your book.toml file. This is done by simply adding an empty output.epub table.

```diff [book] title = "mdBook Documentation" description = "Create book from markdown files. Like Gitbook but implemented in Rust" author = "Mathieu David"

[output.html] mathjax-support = true

• [output.epub] ```

Now everything is set up, just run mdbook as normal and the output directory (book/epub/ by default) should now contain an extra file called mdBook Documentation.epub (substituting in whatever your book's title is).

The mdbook-epub executable can be run in "standalone" mode. This is where the backend can be used without needing to be called by mdbook, useful if you only want to render the EPUB document.

$ mdbook-epub --standalone ./path/to/book/dir

Configuration

Configuration is fairly bare bones at the moment. All you can do is add additional CSS files and disable the default stylesheet.

toml [output.epub] additional-css = ["./path/to/main.css"] use-default-css = false

Planned Features

The following features are planned (a checked box indicates it's complete). This list is by no means complete, so feature requests are most welcome!

• [x] Make a valid EPUB file with the bare chapter contents
• [x] Generate a basic TOC

• [x] Include a default CSS stylesheet ([master.css])
  • [ ] Actually make that stylesheet pretty enough for human consumption
• [x] Include user-defined stylesheets and themes
• [ ] Allow users to tweak the generated page by providing their own template
• [ ] Ensure the generated document is viewable on the following platforms
  • [ ] Amazon Kindle
  • [ ] Sony PRS-T3

Contributing

This backend is still very much in the development phase and as such a large number of features are missing. If you think of something you'd like please create an issue on the [issue tracker]!
