Maruku

Maruku features

Maruku allows you to write in an easy-to-read-and-write syntax, like this:

This document in Markdown

Then it can be translated to HTML:

This document in HTML

or LaTeX, which is then converted to PDF:

This document in PDF

Maruku implements:

• the original Markdown syntax (HTML or PDF), translated by Maruku.

1.1. New meta-data syntax

Maruku implements a syntax that allows to attach “meta” information to objects.

See this proposal for how to attach metadata to the elements.

See the documentation for supported attributes.

Meta-data for the document itself is specified through the use of email headers:

Title: A simple document containing meta-headers
CSS: style.css

Content of the document

When creating the document through

Maruku.new(s).to_html_document

the title and stylesheet are added as expected.

Meta-data keys are assumed to be case-insensitive.

1.2. Automatic generation of the table of contents

If you create a list, and then set the toc attribute, when rendering Maruku will create an auto-generated table of contents.

* This will become a table of contents (this text will be scraped).
{:toc}

You can see an example of this at the beginning of this document.

1.3. Use HTML entities

If you want to use HTML entities, go on! We will take care of the translation to LaTeX:

Entity	Result
©	©
£	£
λ	λ
—	—

See the list of supported entities (pdf).

1.4. This header contains emphasis strong text and code

Note that this header contains formatting and it still works, also in the table of contents.

And This is a link with all sort of weird stuff in the text.

2. Examples of PHP Markdown Extra syntax

• tables

  Col1 | Very very long head | Very very long head|
  -----|:-------------------:|-------------------:|
  cell | center-align        | right-align        |

  Col1	Very very long head	Very very long head
  cell	center-align	right-align

• footnotes ¹

  * footnotes [^foot]
  
  [^foot]: I really was missing those.

• Markdown inside HTML elements

  <div markdown="1" style="border: solid 1px black">
     This is a div with Markdown **strong text**
  </div>

  This is a div with Markdown strong text

• header ids

  ## Download ##     {#download}

  For example, a link to the download header.

• definition lists

  Definition list
  : something very hard to parse

  Definition list

  something very hard to parse

• abbreviations or ABB for short.
