HTML Output
Common utilities and CSS for transformations to HTML.
:Requires: l10n color icons
:Revision:version="1.0" date="2010-05-26" status="final"

This stylesheet contains common templates for creating HTML output. The
*{html.output} template creates an output file for a node in the source XML
document, calling *{html.page} to create the actual output. Output files can
be either XHTML or HTML, depending on the @{html.xhtml} parameter.

This stylesheet matches #{/} and calls *{html.output} on the root XML element.
This works for most input formats. If you need to do something different, you
should override the match for #{/}.
-->
<xsl:template match="/">
  <xsl:call-template name="html.output">
    <xsl:with-param name="node" select="*"/>

html.basename
The base filename of the primary output file.
:Revision:version="1.0" date="2010-05-25" status="final"

This parameter specifies the base filename of the primary output file, without
the filename extension. This is used by *{html.output} to determine the output
filename, and may be used by format-specific linking code. By default, it uses
the value of an #{id} or #{xml:id} attribute, if present. Otherwise, it uses
the static string #{index}.

html.xhtml
Whether to output XHTML.
:Revision:version="1.0" date="2010-05-25" status="final"

If this parameter is set to true, this stylesheet will output XHTML. Otherwise,
the output is assumed to be HTML. Note that for HTML output, the importing
stylesheet still needs to call #{xsl:namespace-alias} to map the XHTML namespace
to #{#default}. The @{html.namespace} will be set automatically based on this
parameter. Stylesheets can use this parameter to check the output type, for
example when using #{xsl:element}.

set automatically based on the ${html.xhtml} parameter, either to the XHTML
namespace, or to the empty namespace. Stylesheets can use this parameter when
using #{xsl:element}.

will be set automatically based on the ${html.xhtml} parameter, either to the
MathML namespace namespace, or to the empty namespace. Stylesheets can use this
parameter when using #{xsl:element}.

:Revision:version="3.18" date="2015-05-04" status="final"

This parameter specifies the XML namespace for SVG in output documents. It
will be set automatically based on the ${html.xhtml} parameter, either to the
SVG namespace namespace, or to the empty namespace. Stylesheets can use this
parameter when using #{xsl:element}.

html.extension
The filename extension for all output files.
:Revision:version="1.0" date="2010-05-25" status="final"

This parameter specifies a filename extension for all HTML output files. It
should include the leading dot. By default, #{.xhtml} will be used if
@{html.xhtml} is true; otherwise, #{.html} will be used.
-->
<xsl:param name="html.extension">

a trailing slash character.

Whether to include syntax highlighting support for code blocks.
:Revision:version="1.0" date="2010-12-06" status="final"

code blocks in the output HTML. Syntax highlighting is done at document load
time by JavaScript.
-->
<xsl:param name="html.syntax.highlight" select="true()"/>


<!--@@==========================================================================
html.output.prefix
An optional path prefix for files output with *{html.output}.
:Revision:version="3.26" date="2017-05-24" status="final"

This parameter allows you to specify an prefix to place before the output path
used by *{html.output} when creating files. You can use this to override the
output directory. Make sure you include a trailing slash, unless you want to
prefix the base file name itself.
-->
<xsl:param name="html.output.prefix" select="''"/>

html.output
Create an HTML output file.
:Revision:version="1.0" date="2010-05-26" status="final"
$node: The node to create an output file for.
$href: The output filename.

This template creates an HTML output file for the source element ${node}. It
uses #{exsl:document} to output the file, and calls *{html.page} with the
${node} parameter to output the actual HTML contents.

If ${href} is not provided, this template will attempt to generate a base
filename and append @{html.extension} to it. The base filename is generated
as follows: If an #{xml:id} attribute is present, it is used; otherwise, if
an #{id} attribute is present, it is uses; otherwise, if ${node} is the root
element, @{html.basename} is used; otherwise, #{generate-id()} is called.

This template prepends @{html.output.prefix} to the value of ${href} when
it calls #{exsl:document}, regardless of whether ${href} was passed in or
generated automatically.

After calling #{exsl:document}, this template calls the %{html.output.after.mode}
mode on ${node}. Importing stylesheets that create multiple output files can
use this to process output files without blocking earlier output.

html.page
Create an HTML document.
:Revision:version="3.26" date="2017-08-04" status="final"
$node: The node to create HTML for.

This template creates the actual HTML output for ${node}. It outputs top-level
elements and container divs, and calls various templates and modes to output
the inner content. Importing stylesheets should implement at least
%{html.title.mode} and %{html.body.mode} for any elements that could be passed
as ${node} to this template. Importing stylesheets should also implement
%{html.header.mode} to output link trails and %{html.footer.mode} to output
credits and other page information.

This template outputs the HTML #{body} element, which takes it attributes
from two sources. First, it calls *{html.lang.attrs}, which automatically
outputs correct #{lang}, #{xml:lang}, and #{dir} attributes. It then calls
%{html.body.attr.mode} on ${node} for additional attributes.

This template also calls a number of stub templates that can be overridden
by extension stylesheets. Override the *{html.head.custom} template to put
custom content at the end of the HTML #{head} element. Override the
*{html.head.top.custom} template to put custom content at the beginning of
the HTML #{head} element. Override the *{html.top.custom} and
*{html.bottom.custom} templates to add site-specific content at the top and
bottom of the page. Override the *{html.header.custom} and *{html.footer.custom}
templates to provide additional content directoy above and below the main
content. Override *{html.sidebar.custom} to create sidebars.

This template also calls *{html.css} and *{html.js} to output CSS and JavaScript
elements. See those templates for further extension points.

This template outputs CSS for elements from source languages like DocBook and

the simpler element names from Mallard, although there some class names which
are not taken from Mallard. Stylesheets which convert to HTML should use the
appropriate common classes.

All parameters can be automatically computed if not provided.

$node: The node to create CSS for.
$direction: The directionality of the text, either #{ltr} or #{rtl}.
$left: The starting alignment, either #{left} or #{right}.
$right: The ending alignment, either #{left} or #{right}.

This template outputs CSS to support syntax highlighting of code blocks. Syntax
highlighting is done at document load time with JavaScript. Text in code blocks
is broken up into chunks and wrapped in HTML elements with particular classes.
This template outputs CSS to match those elements and style them with the
built-in themeable colors from !{color}.

All parameters can be automatically computed if not provided.

html.lang.attrs
Output #{lang} and #{dir} attributes.
:Revision: version="1.0" date="2010-06-10" status="final"
$node: The current element in the input document.
$parent: A parent node to take ${lang} and ${dir} from.
$lang: The language for ${node}.
$dir: The text directionality for ${node}.

This template outputs #{lang}, #{xml:lang}, or #{dir} attributes if necessary.
If ${lang} is not set, it will be taken from the #{xml:lang} or #{lang}
attribute of ${node}. If ${dir} is not set, it will be taken from the #{its:dir}
attribute of ${node} or computed based on ${lang}.

The ${parent} parameter defaults to an empty node set. If it is set to a
non-empty node set, this template will attempt to get ${lang} and ${dir} from
${parent} if they are not set on ${node}. This is occasionally useful when a
wrapper element in a source language doesn't directly create any output
elements.

This template outputs either an #{xml:lang} or a #{lang} attribute, depending
on whether @{html.xhtml} is #{true}. It only outputs an #{xml:lang} or #{lang}
attribute if $lang is non-empty. This template also outputs a #{dir} attribute
if ${dir} is non-empty.

elements that may be syntax highlighted, then call this template when building
the #{class} attribute for output elements.
