Markdown is a text-to-HTML conversion tool for web writers, allowing you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).
Implementations:
- WMD, an amazing JavaScript editor specifically tailored for using Markdown.
- Make.text – a bookmarklet for translating a web page into Markdown.
- PyMarkdown – for Python, obviously.
- python-markdown2 a second Python implementation, with some improvements.
- BlueCloth for Ruby
- PHP implementation
- C# / .NET implementation
- JavaScript partial implementation, a better one called “Showdown”.
- A more complete list maintained by François Granger, who is developing a markup converter.
