\section about_history History

The implementation of this documentation set is based on the fantastic work of the
<a href="https://eigen.tuxfamily.org/index.php?title=Main_Page">Eigen project</a>.
Please refer to their <a href="https://gitlab.com/libeigen/eigen">GitLab repository</a>
and the online version of their
<a href="http://eigen.tuxfamily.org/dox/">Doxygen-based documentation</a>.
Not only does Eigen set a standard as a piece of software, but also as an example
of <em>documentation done right</em>. And kudos to the
<a href="https://github.com/jothepro/doxygen-awesome-css">Doxygen Awesome project</a>
for their style sheets.

\section about_documentation Documentation about Documentation

In this section, we describe common documentation maintenance tasks.

\subsection plain_html Including Plain HTML Pages

The most common use case for this is the inclusion of older documentation.
New documentation should, whenever possible, be created using Doxygen markdown!

Use Doxygen's <a href="https://www.doxygen.nl/manual/commands.html#cmdhtmlinclude"><code>htmlinclude</code></a>
special command to include existing plain HTML pages.

An example from this documentation set can be seen
<a href="https://\SRCURL/doxygen/dox/FileFormatSpec.dox">here</a>.

\subsection new_rm_entry Creating a New Reference Manual Entry

Please refer to the \ref RMT for guidance on how to create a new reference manual entry.

\subsubsection new_example Adding and Referencing API Examples

For each HDF5 module, such as \TText{H5F}, there is an examples source file called
\TText{H5*_examples.c}. For example, the \TText{H5F} API examples are located in
<a href="https://\SRCURL/doxygen/examples/H5F_examples.c">
<code>H5F_examples.c</code></a>. Examples are code blocks marked as Doxygen
<a href="https://www.doxygen.nl/manual/commands.html#cmdsnippet">snippets</a>.
For example, the source code for the H5Fcreate() API sample is located between
the
\verbatim
//! <!-- [create] -->
...
//! <!-- [create] -->
\endverbatim
comments in
<a href="https://\SRCURL/doxygen/examples/H5F_examples.c">
<code>H5F_examples.c</code></a>.

Add a new API example by adding a new code block enclosed between matching
snippet tags. The name of the tag is usually the function name stripped of
the module prefix.

The inclusion of such a block of code can then be triggered via Doxygen's
<a href="https://www.doxygen.nl/manual/commands.html#cmdsnippet"><code>snippet</code></a>
special command. For example, the following markup
\verbatim
* \snippet H5F_examples.c create
\endverbatim
yields
\snippet H5F_examples.c create

\subsubsection api_macro Adding an API Macro

API macros are handled by the <code>api_vers_2, api_vers_3, api_vers_4</code>
custom commands. The numbers indicate the number of potential API function
mappings. For example, H5Acreate() has two potential mappings, H5Acreate1() and
H5Acreate2(). To trigger the creation of a reference manual entry for H5Acreate()
use the following markup:
\verbatim
\api_vers_2{H5Acreate,H5Acreate1,H5Acreate2}
\endverbatim
This yields:

\api_vers_2{H5Acreate,H5Acreate1,H5Acreate2}

\subsection custom_commands Creating Custom Commands

See Doxygen's <a href="https://www.doxygen.nl/manual/custcmd.html">Custom Commands documentation</a>
as a general reference.

All custom commands for this project are located in the
<a href="https://\SRCURL/doxygen/aliases"><tt>aliases</tt></a>
file in the <a href="https://\SRCURL/doxygen"><tt>doxygen</tt></a>
subdirectory of the <a href="https://github.com/HDFGroup/hdf5">main HDF5 repo</a>.

The custom commands are grouped in sections. Find a suitable section for your command or
ask for help if unsure!

\subsection new_rfc Adding a New RFC or Referencing an Existing RFC

For ease of reference, we define custom commands for each RFC in the <tt>RFCs</tt> section
of the
<a href="https://\SRCURL/doxygen/aliases"><tt>aliases</tt></a>
file. For example the custom command \TText{ref_rfc20141210} can be used to insert a
reference to "RFC: Virtual Object Layer". In other words, the markup
\verbatim
\ref_rfc20141210
\endverbatim
yields a clickable link:

\ref_rfc20141210

To add a new RFC, add a custom command for the RFC to the
<a href="https://\SRCURL/doxygen/aliases"><tt>aliases</tt></a>
file. The naming convention for the custom command is \TText{ref_rfcYYYYMMDD},
where \TText{YYYYMMDD} is the ID of the RFC. The URL is composed of the prefix
\verbatim
https://\RFCURL/
\endverbatim
and the name of your RFC file, typically, a PDF file, i.e., the full URL would
be
\verbatim
https://\RFCURL/my_great_rfc_name.pdf
\endverbatim
