Haunted Markdown

[work in progress]...obviously

Haunted Markdown is based on John Gruber's original Markdown project, and borrows from Github Flavored Markdown and MultiMarkdown. It has a focus on producing consistent results whilst editing, so that the experience of live previewing is smooth.

Features

Haunted Markdown should support the following features:

• Markdown escaping of & and <
• Markdown paragraphs and line breaks
• Setext & atx style headings i.e. headings prefixed with # or underlined with _ or =
• GFM style line breaking
• Blockquote with >, indented blockquotes
• Horizontal rules with * * *, ***, *****, - - -, ----------------------
• Emphasis with * & _, and strong with ** & __ but which allows spaces at the end of the string between the markdown characters so that the style of the output doesn't change whilst typing.
• GFM style handling of underscores inside words
• Strike through with ~~
• Bulleted lists with * or -, numbered lists
• Advanced list indenting (needs much consideration)
• Reference and inline links, with titles [alt](http://ghost.org "optional title") or [ref]: http://ghost.org "optional title"
• Reference and inline images, with titles/captions
• Reference and inline video, with titles/captions (we don't know what this is gonna look like yet)
• Both Markdown and GFM style autolinking
• Indented, fenced and inline code blocks
• Full HTML support
