Description

DenDenMarkdown is an extended Markdown syntax fitted for Japanese and EPUB publishing.
Denden_extension enables the following DenDenMarkdown syntax in Python-Markdown.

• Japanese Ruby Annotation
• Tate-Chu-Yoko
• Footnotes with epub:type attribute *1
• EPUB pagebreak syntax
• Chunk file syntax *2

*1 Denden_extension depends on the Python-Markdown's footnotes extension for implementing this feature. So you also need the markdown.extensions.footnotes or markdown.extensions.extra which includes the footnotes extension.
*2 Three or more equal signs ('=') on a line by themselves is replaced by a horizontal rule tag with docbreak class attribute (<hr class="docbreak" />).

DenDenMarkdown inherits its syntax from PHP Markdown Extra. In Python-Markdown, PHP Markdown Extra syntax is enabled by markdown.extensions.extra and markdown.extensions.sane_lists, which are included in the Python-Markdown Library.
Also, DenDenMarkdown adopts GFM style line break. This can be enabled by markdown.extensions.nl2br, which is included with the Python-Markdown too.

If you only want to use DenDenMarkdown's original syntax, you just need to designate only markdown.extensions.footnotes and denden_extension.
If you don't use footnotes, only denden_extension is necessary.

The following syntax of DenDenMarkdown is not implemented in denden_extension.

• Twitter account autolink syntax
