@node Markup
@section Markup
@defun sxml->ansi-text tree
Takes an HTML-like document in SXML format, and produces a formatted
string with embedded ANSI-escapes suitable to print to a terminal.
Supported tags are:
@table @samp
@item group
@item block
Groups elements, concatenating their format. Mainly here for helper
procedres and the like. Also used for the root node.
@item header
Centers and bolds its content. Attributes will be sent along to the
inner @code{<center/>} tag.
@item center
Center its contents on the line. The output is undefined if the body
serializes to a multiline string.
@item p
A text paragraph. Justifies the content inside.
Ends with a double newline, unless the parameter @code{inline} is set.
@item b
Make content bold.
@item i
@item em
Make content italics.
@item code
Format content as code.
(currently does nothing since we only support output to terminal)
@item blockquote
Justifies content, and sets it slightly indented.
@item ws
Forces horizontal whitespace. Use the parameter @code{minwidth} to
specify how many spaces should be inserted.
@item br
Forces a linebreak.
@item hr
Generates a horrizontal line.
@item dl
Declares a description list.
@item dt
A key in a description list, only valid inside @code{dl}.
@item dd
A value of a description list, only valid inside @code{dl}.
@item scheme
Set content as Scheme code. The content will be passed through Guile's
pretty-print.
@end table
Almost all of the block environments accept the attribute @var{width},
which specifies the desired output width.
@end defun
