[SOLVED] Compare and contrast the lightweight markup languages

Compare and contrast the lightweight markup languages

Please identify the most popular lightweight markup languages and compare their strengths and weaknesses. These languages should be general-purpose markup for technical prose, such as for documentation (for example, Haml doesn't count).

Solution

I know of three main languages used commonly in the greater programming and tech community: Textile, Markdown, and reStructuredText. All three can be learned in a couple of hours or "winged" with the cheat sheet nearby.

Textile

Used by Redmine and the Ruby community

The most similar to HTML, but least readable source
Easiest nested lists of all three languages
Not understandable to non-programmers or the HTML-ignorant
Ideal for complex short documents (with links, nested lists, code, custom HTML); for example: short documentation, how-tos, blog or CMS content
Syntax reference

Markdown

Doesn't seem to have a home language "community" but...

Emphasizes source code readability, similar to email traditions
Straightforward HTML embedding (you just type the tags out)
No way to make tables besides embedding HTML
You know it already if you know Stack Overflow
Easy to learn if you already know reStructuredText
Automatic email address obfuscation for the format <address@example.com> (with angle brackets)
Syntax reference

reStructuredText (A.K.A. ReST)

Popular in the Python community

A bit persnickety about whitespace and alignment if you ask me
Lists (especially nested lists) and paragraphs always seem to get in fights
Readable by non-programmers
Only format which can build a table of contents (via an extension in the Python reference implementation)
Directly converts to other formats like PDF and XML
Ideal for large documents with lots of prose (e.g. an alternative to docbook for a user manual)
Syntax reference
