<section xml:id="doc_style.doxygen"><info><title>Doxygen</title></info>
<section xml:id="doxygen.prereq"><info><title>Prerequisites</title></info>
<para>
Prerequisite tools are Bash 2.0 or later,
<link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.doxygen.org/">Doxygen</link>, and
the <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.gnu.org/software/coreutils/">GNU
coreutils</link>. (GNU versions of find, xargs, and possibly
sed and grep are used, just because the GNU versions make
things very easy.)
</para>
<para>
To generate the pretty pictures and hierarchy
graphs, the
<link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.graphviz.org">Graphviz</link> package
will need to be installed. For PDF
output, <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.tug.org/applications/pdftex/">
pdflatex</link> is required.
</para>
</section>
<section xml:id="doxygen.rules"><info><title>Generating the Doxygen Files</title></info>
<para>
The following Makefile rules run Doxygen to generate HTML
docs, XML docs, XML docs as a single file, PDF docs, and the man pages.
</para>

</para>
<para>
Generated files are output into separate sub directores of
<filename class="directory">doc/doxygen/</filename> in the
build directory, based on the output format. For instance, the
HTML docs will be in <filename class="directory">doc/doxygen/html</filename>.
</para>
<para>
Careful observers will see that the Makefile rules simply call
a script from the source tree, <filename>run_doxygen</filename>, which
does the actual work of running Doxygen and then (most
importantly) massaging the output files. If for some reason
you prefer to not go through the Makefile, you can call this
script directly. (Start by passing <literal>--help</literal>.)
</para>
<para>
If you wish to tweak the Doxygen settings, do so by editing
<filename>doc/doxygen/user.cfg.in</filename>. Notes to fellow
library hackers are written in triple-# comments.
</para>
</section>
<section xml:id="doxygen.markup"><info><title>Markup</title></info>
<para>
In general, libstdc++ files should be formatted according to
the rules found in the
<link linkend="contrib.coding_style">Coding Standard</link>. Before
any doxygen-specific formatting tweaks are made, please try to
make sure that the initial formatting is sound.
</para>
<para>
Adding Doxygen markup to a file (informally called
<quote>doxygenating</quote>) is very simple. The Doxygen manual can be
found
<link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.stack.nl/~dimitri/doxygen/download.html#latestman">here</link>.
We try to use a very-recent version of Doxygen.
</para>
<para>
For classes, use
<classname>deque</classname>/<classname>vector</classname>/<classname>list</classname>
and <classname>std::pair</classname> as examples. For
functions, see their member functions, and the free functions
in <filename>stl_algobase.h</filename>. Member functions of
other container-like types should read similarly to these
member functions.
</para>
<para>
Some commentary to accompany
the first list in the <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.stack.nl/~dimitri/doxygen/docblocks.html">Special
Documentation Blocks</link> section of
the Doxygen manual:
</para>
<orderedlist inheritnum="ignore" continuation="restarts">
<listitem>
<para>For longer comments, use the Javadoc style...</para>
</listitem>
<listitem>
<para>
...not the Qt style. The intermediate *'s are preferred.
</para>
</listitem>
<listitem>
<para>
Use the triple-slash style only for one-line comments (the
<quote>brief</quote> mode).
</para>
</listitem>
<listitem>
<para>
This is disgusting. Don't do this.
</para>
</listitem>
</orderedlist>
<para>
Some specific guidelines:
</para>
<para>
Use the @-style of commands, not the !-style. Please be
careful about whitespace in your markup comments. Most of the
time it doesn't matter; doxygen absorbs most whitespace, and
both HTML and *roff are agnostic about whitespace. However,
in &lt;pre&gt; blocks and @code/@endcode sections, spacing can
have <quote>interesting</quote> effects.
</para>
<para>
Use either kind of grouping, as
appropriate. <filename>doxygroups.cc</filename> exists for this
purpose. See <filename>stl_iterator.h</filename> for a good example
of the <quote>other</quote> kind of grouping.
</para>
<para>
Please use markup tags like @p and @a when referring to things
such as the names of function parameters. Use @e for emphasis
when necessary. Use @c to refer to other standard names.
(Examples of all these abound in the present code.)
</para>
<para>
Complicated math functions should use the multi-line
format. An example from <filename>random.h</filename>:
</para>
<para>
<literallayout class="normal">
/**
* @brief A model of a linear congruential random number generator.
*
* @f[
* x_{i+1}\leftarrow(ax_{i} + c) \bmod m
* @f]
*/
</literallayout>
</para>
<para>
Be careful about using certain, special characters when
writing Doxygen comments. Single and double quotes, and
separators in filenames are two common trouble spots. When in
doubt, consult the following table.

<para>
Editing the DocBook sources requires an XML editor. Many
exist: some notable options
include <command>emacs</command>, <application>Kate</application>,
or <application>Conglomerate</application>.
</para>
<para>
Some editors support special <quote>XML Validation</quote>
modes that can validate the file as it is
produced. Recommended is the <command>nXML Mode</command>
for <command>emacs</command>.
</para>
<para>
Besides an editor, additional DocBook files and XML tools are
also required.
</para>
<para>
Access to the DocBook 5.0 stylesheets and schema is required. The
stylesheets are usually packaged by vendor, in something
like <filename>docbook5-style-xsl</filename>. To exactly match
generated output, please use a version of the stylesheets
equivalent
to <filename>docbook5-style-xsl-1.75.2-3</filename>. The
installation directory for this package corresponds to
the <literal>XSL_STYLE_DIR</literal>
in <filename>doc/Makefile.am</filename> and defaults
to <filename class="directory">/usr/share/sgml/docbook/xsl-ns-stylesheets</filename>.
</para>
<para>
For processing XML, an XML processor and some style
sheets are necessary. Defaults are <command>xsltproc</command>
provided by <filename>libxslt</filename>.
</para>
<para>
For validating the XML document, you'll need
something like <command>xmllint</command> and access to the
relevant DocBook schema. These are provided
by a vendor package like <filename>libxml2</filename> and <filename>docbook5-schemas-5.0-4</filename>
</para>
<para>
For PDF output, something that transforms valid Docbook XML to PDF is
required. Possible solutions include <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://dblatex.sourceforge.net">dblatex</link>,
<command>xmlto</command>, or <command>prince</command>. Of
these, <command>dblatex</command> is the default. Other
options are listed on the DocBook web <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://wiki.docbook.org/topic/DocBookPublishingTools">pages</link>. Please
consult the <email>libstdc++@gcc.gnu.org</email> list when
preparing printed manuals for current best practice and
suggestions.
</para>
<para>
For Texinfo output, something that transforms valid Docbook
XML to Texinfo is required. The default choice is <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://docbook2x.sourceforge.net/">docbook2X</link>.
</para>
<para>
Please make sure that the XML documentation and markup is valid for
any change. This can be done easily, with the validation rule
detailed below, which is equivalent to doing:
</para>
<screen>
<userinput>
xmllint --noout --valid <filename>xml/index.xml</filename>
</userinput>
</screen>
</section>
<section xml:id="docbook.rules"><info><title>Generating the DocBook Files</title></info>
<para>
The following Makefile rules generate (in order): an HTML
version of all the DocBook documentation, a PDF version of the same, a
single XML document, and the result of validating the entire XML
document.
</para>
<para>
<screen><userinput>make doc-html-docbook</userinput></screen>
</para>
<para>
<screen><userinput>make doc-pdf-docbook</userinput></screen>

<para>
<screen><userinput>make doc-xml-single-docbook</userinput></screen>
</para>
<para>
<screen><userinput>make doc-xml-validate-docbook</userinput></screen>
</para>
<para>
Generated files are output into separate sub directores of
<filename class="directory">doc/docbook/</filename> in the
build directory, based on the output format. For instance, the
HTML docs will be in <filename class="directory">doc/docbook/html</filename>.
</para>

<emphasis>Which files are important</emphasis>
All Docbook files are in the directory
libstdc++-v3/doc/xml
Inside this directory, the files of importance:
spine.xml - index to documentation set
manual/spine.xml - index to manual
manual/*.xml - individual chapters and sections of the manual
faq.xml - index to FAQ
api.xml - index to source level / API

<para>
Documentation for the GNU C++ Library is created from three
independent sources: a manual, a FAQ, and an API reference.
</para>
<para>
The sub-directory <filename class="directory">doc</filename>
within the main source directory contains
<filename>Makefile.am</filename> and
<filename>Makefile.in</filename>, which provide rules for
generating documentation, described in excruciating detail
below. The <filename class="directory">doc</filename>
sub-directory also contains three directories: <filename
class="directory">doxygen</filename>, which contains scripts and
fragments for <command>doxygen</command>, <filename
class="directory">html</filename>, which contains an html
version of the manual, and <filename
class="directory">xml</filename>, which contains an xml version
of the manual.
</para>
<para>
Diverging from established documentation conventions in the rest
of the GCC project, libstdc++ does not use Texinfo as a markup
language. Instead, Docbook is used to create the manual and the
FAQ, and Doxygen is used to construct the API
reference. Although divergent, this conforms to the GNU Project
recommendations as long as the output is of sufficient quality,
as per
<link xmlns:xlink="http://www.w3.org/1999/xlink"

<title>Generating Documentation</title>
</info>
<para>
Certain Makefile rules are required by the GNU Coding
Standards. These standard rules generate HTML, PDF, XML, or man
files. For each of the generative rules, there is an additional
install rule that is used to install any generated documentation
files into the prescribed installation directory. Files are
installed into <filename class="directory">share/doc</filename>
or <filename class="directory">share/man</filename> directories.
</para>
<para>
The standard Makefile rules are conditionally supported, based
on the results of examining the host environment for
prerequisites at configuration time. If requirements are not
found, the rule is aliased to a dummy rule that does nothing,
and produces no documentation. If the requirements are found,
the rule forwards to a private rule that produces the requested
documentation.
</para>
<para>
For more details on what prerequisites were found and where,
please consult the file <filename>config.log</filename> in the
libstdc++ build directory. Compare this log to what is expected
for the relevant Makefile conditionals:
<literal>BUILD_INFO</literal>, <literal>BUILD_XML</literal>,
<literal>BUILD_HTML</literal>, <literal>BUILD_MAN</literal>,

The following Makefile rules run Doxygen to generate HTML

Generated files are output into separate sub directories of

build directory, based on the output format. For instance, the
HTML docs will be in <filename class="directory">doc/doxygen/html</filename>.
</para>
<para>
Careful observers will see that the Makefile rules simply call
a script from the source tree, <filename>run_doxygen</filename>, which
does the actual work of running Doxygen and then (most
importantly) massaging the output files. If for some reason
you prefer to not go through the Makefile, you can call this
script directly. (Start by passing <literal>--help</literal>.)

If you wish to tweak the Doxygen settings, do so by editing

<section xml:id="doxygen.markup"><info><title>Markup</title></info>
<para>
In general, libstdc++ files should be formatted according to
the rules found in the
<link linkend="contrib.coding_style">Coding Standard</link>. Before
any doxygen-specific formatting tweaks are made, please try to
make sure that the initial formatting is sound.
</para>
<para>
Adding Doxygen markup to a file (informally called
<quote>doxygenating</quote>) is very simple. The Doxygen manual can be
found
<link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://www.stack.nl/~dimitri/doxygen/download.html#latestman">here</link>.
We try to use a very-recent version of Doxygen.
</para>
<para>
For classes, use
<classname>deque</classname>/<classname>vector</classname>/<classname>list</classname>
and <classname>std::pair</classname> as examples. For
functions, see their member functions, and the free functions
in <filename>stl_algobase.h</filename>. Member functions of
other container-like types should read similarly to these
member functions.

</para>
</listitem>
</orderedlist>
<para>
Some specific guidelines:
</para>
<para>
Use the @-style of commands, not the !-style. Please be
careful about whitespace in your markup comments. Most of the
time it doesn't matter; doxygen absorbs most whitespace, and
both HTML and *roff are agnostic about whitespace. However,
in &lt;pre&gt; blocks and @code/@endcode sections, spacing can
have <quote>interesting</quote> effects.
</para>
<para>
Use either kind of grouping, as
appropriate. <filename>doxygroups.cc</filename> exists for this
purpose. See <filename>stl_iterator.h</filename> for a good example
of the <quote>other</quote> kind of grouping.
</para>
<para>
Please use markup tags like @p and @a when referring to things
such as the names of function parameters. Use @e for emphasis
when necessary. Use @c to refer to other standard names.
(Examples of all these abound in the present code.)
</para>
<para>
Complicated math functions should use the multi-line
format. An example from <filename>random.h</filename>:
</para>
<para>
<literallayout class="normal">
/**
* @brief A model of a linear congruential random number generator.
*
* @f[
* x_{i+1}\leftarrow(ax_{i} + c) \bmod m
* @f]
*/
</literallayout>
</para>
<para>
One area of note is the markup required for
<literal>@file</literal> markup in header files. Two details
are important: for filenames that have the same name in
multiple directories, include part of the installed path to
disambiguate. For example:
</para>
<para>
<literallayout class="normal">
/** @file debug/vector
* This file is a GNU debug extension to the Standard C++ Library.
*/
</literallayout>
</para>
<para>
The other relevant detail for header files is the use of a
libstdc++-specific doxygen alias that helps distinguish
between public header files (like <filename>random</filename>)
from implementation or private header files (like
<filename>bits/c++config.h</filename>.) This alias is spelled
<literal>@headername</literal> and can take one or two
arguments that detail the public header file or files that
should be included to use the contents of the file. All header
files that are not intended for direct inclusion must use
<literal>headername</literal> in the <literal>file</literal>
block. An example:
</para>
<para>
<literallayout class="normal">
/** @file bits/basic_string.h
* This is an internal header file, included by other library headers.
* Do not attempt to use it directly. @headername{string}
*/
</literallayout>
</para>
<para>
Be careful about using certain, special characters when
writing Doxygen comments. Single and double quotes, and
separators in filenames are two common trouble spots. When in
doubt, consult the following table.

Editing the DocBook sources requires an XML editor. Many
exist: some notable options
include <command>emacs</command>, <application>Kate</application>,
or <application>Conglomerate</application>.
</para>
<para>
Some editors support special <quote>XML Validation</quote>
modes that can validate the file as it is
produced. Recommended is the <command>nXML Mode</command>
for <command>emacs</command>.
</para>
<para>
Besides an editor, additional DocBook files and XML tools are
also required.
</para>
<para>
Access to the DocBook 5.0 stylesheets and schema is required. The
stylesheets are usually packaged by vendor, in something
like <filename>docbook5-style-xsl</filename>. To exactly match
generated output, please use a version of the stylesheets
equivalent
to <filename>docbook5-style-xsl-1.75.2-3</filename>. The
installation directory for this package corresponds to
the <literal>XSL_STYLE_DIR</literal>
in <filename>doc/Makefile.am</filename> and defaults
to <filename class="directory">/usr/share/sgml/docbook/xsl-ns-stylesheets</filename>.
</para>
<para>
For processing XML, an XML processor and some style
sheets are necessary. Defaults are <command>xsltproc</command>
provided by <filename>libxslt</filename>.
</para>
<para>
For validating the XML document, you'll need
something like <command>xmllint</command> and access to the
relevant DocBook schema. These are provided
by a vendor package like <filename>libxml2</filename> and <filename>docbook5-schemas-5.0-4</filename>
</para>
<para>
For PDF output, something that transforms valid Docbook XML to PDF is
required. Possible solutions include <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://dblatex.sourceforge.net">dblatex</link>,
<command>xmlto</command>, or <command>prince</command>. Of
these, <command>dblatex</command> is the default. Other
options are listed on the DocBook web <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://wiki.docbook.org/topic/DocBookPublishingTools">pages</link>. Please
consult the <email>libstdc++@gcc.gnu.org</email> list when
preparing printed manuals for current best practice and
suggestions.
</para>
<para>
For Texinfo output, something that transforms valid Docbook
XML to Texinfo is required. The default choice is <link xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="http://docbook2x.sourceforge.net/">docbook2X</link>.

After editing the xml sources, please make sure that the XML
documentation and markup is still valid. This can be
done easily, with the following validation rule:
</para>
<screen>
<userinput>make doc-xml-validate-docbook</userinput>
</screen>
<para>
This is equivalent to doing:
</para>
<screen>
<userinput>
xmllint --noout --valid <filename>xml/index.xml</filename>
</userinput>
</screen>
<para>
Please note that individual sections and chapters of the
manual can be validated by substiuting the file desired for
<filename>xml/index.xml</filename> in the command
above. Reducing scope in this manner can be helpful when
validation on the entire manual fails.
