Differences from Markdown

View the input spec and output spec for an example.

Images

Images are not supported. They render to links. For example, ![example](/image.png) becomes [url=/image.png]example[/url].

Underlines ([u])

Wrapping text with __ does not make it bold, but makes it underlined (__underlined text__).

Spoiler Text ([spoiler])

Wrapping text with !!! makes it spoiler text (!!!hidden text!!!).

Quote Authors

Quotes can have authors by adding (author) after text preceded with a >. For this reason, continuing a quote on a newline without preceding each line with a > is considered undocumented behavior.

Example

>this is some text that I'm
>responding to.
(some person)

Literal Text ([noparse])

Steam's [noparse] tag instructs Steam to render text like [b]this[/b] literally, without styling. In addition to rendering a [noparse] block, steamdown's literal text rule will also prevent parsing of the source text. For example, *this* would not be converted to [i]this[/i].

Inline

Text can be made literal by wrapping it with {{{ and }}} ({{{[b]The bold tag is rendered[/b]}}}).

Block Level

Any lines between {{{ and }}} will be rendered without any parsing.

Example

{{{
[b] is bold
[u] is underline
}}}

Limitations

Steam supports tables with no borders ([table noborder=1]) and equal-width cells ([table equalcells=1]). These are not currently supported. Syntax proposals welcome!
