Basic article structure
=======================
A *custom interpreted text role* (:duref:`ref <roles>`) is an inline piece of
explicit markup. It signifies that that the enclosed text should be interpreted
in a specific way. The general syntax is ``:rolename:`content```.
The basic structure of an article makes use of heading adornments to markup
chapter, sections and subsections.
Docutils supports the following roles:
#. ``=`` with overline for document title
#. ``=`` for chapters
#. ``-`` for sections
#. ``~`` for subsections
* :durole:`emphasis` -- equivalent of ``*emphasis*``
* :durole:`strong` -- equivalent of ``**strong**``
* :durole:`literal` -- equivalent of ````literal````
* :durole:`subscript` -- subscript text
* :durole:`superscript` -- superscript text
* :durole:`title-reference` -- for titles of books, periodicals, and other
materials

Figures & Images
================
Searx's sphinx setup includes: :ref:`linuxdoc:kfigure`. Scalable here means;
scalable in sense of the build process. Normally in absence of a converter
tool, the build process will break. From the authors POV it’s annoying to care
about the build process when handling with images, especially since he has no
access to the build process. With :ref:`linuxdoc:kfigure` the build process
continues and scales output quality in dependence of installed image processors.
If you want to add an image, you should use the ``kernel-figure`` and
``kernel-image`` directives. E.g. to insert a figure with a scalable image
format use SVG (:ref:`svg_image_example`):
.. code:: reST
.. _svg image example:
.. kernel-figure:: svg_image.svg
:alt: simple SVG image
SVG image example
.. _svg image example:
.. kernel-figure:: svg_image.svg
:alt: simple SVG image
SVG image example
DOT files (aka Graphviz)
------------------------
The kernel figure (and image) directive support **DOT** formated files, see
* DOT: http://graphviz.org/pdf/dotguide.pdf
* Graphviz: http://www.graphviz.org/content/dot-language
A simple example (:ref:`hello_dot_file`):
.. code:: reST
.. kernel-figure:: hello.dot
:alt: hello world
DOT's hello world example
.. admonition:: hello.dot
:class: rst-example
.. code:: reST
.. kernel-figure:: hello.dot

``kernel-render`` DOT
---------------------
Lorem ipsum dolor sit amet, consectetur adipisici elit ..
Further read :ref:`chapter title`.
Embed *render* markups (or languages) like Graphviz's **DOT** is provided by the
``kernel-render`` directives.

"bar" -> "baz";
}
Section
-------
How this will be rendered depends on the installed tools. If Graphviz is
installed, you will see an vector image. If not the raw markup is inserted as
*literal-block* (:ref:`hello_dot_render`).

}
The *render* directive has all the options known from the *figure* directive,
plus option ``caption``. If ``caption`` has a value, a *figure* node is
inserted. If not, a *image* node is inserted. A ``caption`` is also needed, if
you want to refer it (:ref:`hello_svg_render`).
