Supported Markups¶

All comments in your code must be formatted in a doxygen-compliant way so that doxygen can do its job. Doxygen provides support for formatting your text with tags, such as \b for adding bold text, this information appears in the xml output and Breathe attempts to reproduce it accurately.

In addition to this, is it possible to add reStructuredText into your comments within appropriately demarcated sections.

reStructuredText¶

Breathe supports reStructuredText within doxygen verbatim blocks which begin with the markup embed:rst. This means that a comment block like this:

/*!
Inserting additional reStructuredText information.
\verbatim embed:rst
.. note::

   This reStructuredText has been handled correctly.
\endverbatim
*/

Will be rendered as:

void rawVerbatim()

Inserting additional reStructuredText information.

Note

This reStructuredText has been handled correctly.

Handling Leading Asterisks¶

Note that doxygen captures all content in a verbatim block. This can be rather an annoyance if you use a leading-asterisk style of comment block such as the following:

/*!
 * Inserting additional reStructuredText information.
 *
 * \verbatim embed:rst
 *     Some example code::
 *
 *        int example(int x) {
 *            return x * 2;
 *        }
 * \endverbatim
 */

As the leading asterisks are captured in the verbatim block this will appear to be an incorrectly formatted bullet list. Due to the syntactical problems Sphinx will issue warnings and the block will render as:

void rawBadAsteriskVerbatim()

Inserting additional reStructuredText information.

Some example code:

int example(int x) {

return x * 2;

}

To prevent this, use an embed:rst:leading-asterisk tag:

/*!
 * Inserting additional reStructuredText information.
 *
 * \verbatim embed:rst:leading-asterisk
 *     Some example code::
 *
 *        int example(int x) {
 *            return x * 2;
 *        }
 * \endverbatim
 */

This will appropriately handle the leading asterisks and render as:

void rawLeadingAsteriskVerbatim()

Inserting additional reStructuredText information.

Some example code:

int example(int x) {
    return x   2;
}

Aliases¶

To make these blocks appears as more appropriate doxygen-like markup in your comments you can add the following aliases to your doxygen configuration file:

ALIASES = "rst=\verbatim embed:rst"
ALIASES += "endrst=\endverbatim"

And, if you use leading asterisks then perhaps:

ALIASES += "rststar=\verbatim embed:rst:leading-asterisk"
ALIASES += "endrststar=\endverbatim"

Which allow you to write comments like:

/*!
Inserting additional reStructuredText information.

\rst

This is some funky non-xml compliant text: <& !><

.. note::

   This reStructuredText has been handled correctly.
\endrst

This is just a standard verbatim block with code:

\verbatim
    child = 0;
    while( child = parent->IterateChildren( child ) )
\endverbatim

*/

Which will be rendered as:

void function()

Inserting additional reStructuredText information.

This is some funky non-XML compliant text: <& !><

Note

This reStructuredText has been handled correctly.

This is just a standard verbatim block with code:

    child = 0;
    while( child = parent->IterateChildren( child ) )
