reST primer
|

===========
|
||||
|
||||
.. sidebar:: KISS_ and readability_
|
||||
|
||||
Instead of defining more and more roles, we at searx encourage our
|
||||
contributors to follow principles like KISS_ and readability_.
|
||||
|
||||
We at searx are using reStructuredText (aka reST_) markup for all kind of
|
||||
documentation, with the builders from the Sphinx_ project a HTML output is
|
||||
generated and deployed at :docs:`github.io <.>`.
|
||||
|
||||
The sources of Searx's documentation are located at :origin:`docs`. Run
|
||||
:ref:`make docs-live <make docs-live>` to build HTML while editing.
|
||||
|
||||
------
|
||||
|
||||
.. contents:: Contents
|
||||
:depth: 3
|
||||
:local:
|
||||
:backlinks: entry
|
||||
|
||||
Sphinx_ and reST_ have their place in the python ecosystem. Over that reST is
|
||||
used in popular projects, e.g the Linux kernel documentation `[kernel doc]`_.
|
||||
|
||||
.. _[kernel doc]: https://www.kernel.org/doc/html/latest/doc-guide/sphinx.html
|
||||
|
||||
.. sidebar:: Content matters
|
||||
|
||||
The readability_ of the reST sources has its value, therefore we recommend to
|
||||
make sparse usage of reST markup / .. content matters!
|
||||
|
||||
**reST** is a plaintext markup language, its markup is *mostly* intuitive and
|
||||
you will not need to learn much to produce well formed articles with. I use the
|
||||
word *mostly*: like everything in live, reST has its advantages and
|
||||
disadvantages, some markups feel a bit grumpy (especially if you are used to
|
||||
other plaintext markups).
|
||||
|
||||
Soft skills
|
||||
===========
|
||||
|
||||
Before going any deeper into the markup let's face on some **soft skills** a
|
||||
trained author brings with, to reach a well feedback from readers:
|
||||
|
||||
- Documentation is dedicated to an audience and answers questions from the
|
||||
audience point of view.
|
||||
- Don't detail things which are general knowledge from the audience point of
|
||||
view.
|
||||
- Limit the subject, use cross links for any further reading.
|
||||
|
||||
To be more concrete what a *point of view* means. In the (:origin:`docs`)
|
||||
folder we have three sections (and the *blog* folder), each dedicate to a
|
||||
different group of audience.
|
||||

||||

|
||||
|
||||
User's POV: :origin:`docs/user`
|
||||
A typical user knows about search engines and might have heard about
|
||||
meta crawlers and privacy.
|
||||
|
||||
Admin's POV: :origin:`docs/admin`
|
||||
A typical Admin knows about setting up services on a linux system, but he does
|
||||
not know all the pros and cons of a searx setup.
|
||||
|
||||
Developer's POV: :origin:`docs/dev`
|
||||
Depending on the readability_ of code, a typical developer is able to read and
|
||||
understand source code. Describe what a item aims to do (e.g. a function),
|
||||
describe chronological order matters, describe it. Name the *out-of-limits
|
||||
condition* and all the side effects a external developer will not know.
|
||||
|
||||
.. _reST inline markup:
|
||||
|
||||
Basic inline markup
|
||||
===================
|
||||
|
||||
``*italics*`` -- *italics*
|
||||
one asterisk for emphasis
|
||||
|
||||
``**boldface**`` -- **boldface**
|
||||
two asterisks for strong emphasis and
|
||||
|
||||
````foo()```` -- ``foo()``
|
||||
backquotes for code samples and literals.
|
||||
|
||||
``\*foo is a pointer`` -- \*foo is a pointer
|
||||
If asterisks or backquotes appear in running text and could be confused with
|
||||
inline markup delimiters, they have to be escaped with a backslash (``\*foo is
|
||||
a pointer``).
|
||||
|
||||
|
||||
Roles
|
||||
=====
|
||||
|
||||
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```.
|
||||
|
||||
Docutils supports the following roles:
|
||||
|
||||
* :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
|
||||
|
||||
Refer to `Sphinx Roles`_ for roles added by Sphinx.
|
||||
|
||||
|
||||
Anchors & Links
|
||||
===============
|
||||
|
||||
.. _reST anchor:
|
||||
|
||||
Anchors
|
||||
-------
|
||||
|
||||
.. _ref role:
|
||||
https://www.sphinx-doc.org/en/master/usage/restructuredtext/roles.html#role-ref
|
||||
|
||||
To refer a point in the documentation a anchor is needed. The :ref:`reST
|
||||
template <reST template>` shows an example where a chapter titled *"Chapters"*
|
||||
gets an anchor named ``chapter title``. Another example from *this* document,
|
||||
where the anchor named ``reST anchor``:
|
||||
|
||||
.. code:: reST
|
||||
|
||||
.. _reST anchor:
|
||||
|
||||
Anchors
|
||||
-------
|
||||
|
||||
To refer a point in the documentation a anchor is needed ...
|
||||
|
||||
To refer anchors use the `ref role`_ markup:
|
||||
|
||||
.. code:: reST
|
||||
|
||||
Visit chapter :ref:`reST anchor`.
|
||||
Or set hyperlink text manualy :ref:`foo bar <reST anchor>`.
|
||||
|
||||
.. admonition:: ``:ref:`` role
|
||||
:class: rst-example
|
||||
|
||||
Visist chapter :ref:`reST anchor`
|
||||
Or set hyperlink text manualy :ref:`foo bar <reST anchor>`.
|
||||
|
||||
.. _reST ordinary ref:
|
||||
|
||||
link ordinary URL
|
||||
-----------------
|
||||
|
||||
If you need to reference external URLs use *named* hyperlinks to maintain
|
||||
readability of reST sources. Here is a example taken from *this* article:
|
||||
|
||||
.. code:: reST
|
||||
|
||||
.. _Sphinx Field Lists:
|
||||
https://www.sphinx-doc.org/en/master/usage/restructuredtext/field-lists.html
|
||||
|
||||
With the *named* hyperlink `Sphinx Field Lists`_, the raw text is much more
|
||||
readable.
|
||||
|
||||
And this shows the alternative (less readable) hyperlink markup `Sphinx Field
|
||||
Lists
|
||||
<https://www.sphinx-doc.org/en/master/usage/restructuredtext/field-lists.html>`__.
|
||||
|
||||
.. admonition:: Named hyperlink
|
||||
:class: rst-example
|
||||
|
||||
With the *named* hyperlink `Sphinx Field Lists`_, the raw text is much more
|
||||
readable.
|
||||
|
||||
And this shows the alternative (less readable) hyperlink markup `Sphinx Field
|
||||
Lists
|
||||
<https://www.sphinx-doc.org/en/master/usage/restructuredtext/field-lists.html>`__.
|
||||

----------------
|
||||
|
||||
With the power of sphinx.ext.extlinks_ and intersphinx_ referencing external
|
||||
content becomes smart. To refer ...

Intersphinx is configured in :origin:`docs/conf.py`:

To list all anchors of the inventory (e.g. ``python``) use:

|

.. code:: sh

chapter, sections and subsections.

||||

List markups

============
|
||||
|
||||
Bullet list
|
||||
-----------
|
||||
|
||||
List markup (:duref:`ref <bullet-lists>`) is simple:
|
||||
|
||||
.. code:: reST
|
||||
|
||||
- This is a bulleted list.
|
||||
|
||||
1. Nested lists are possible, but be aware that they must be separated from
|
||||
the parent list items by blank line
|
||||
2. Second item of nested list
|
||||
|
||||
- It has two items, the second
|
||||
item uses two lines.
|
||||
|
||||
#. This is a numbered list.
|
||||
#. It has two items too.
|
||||
|
||||
.. admonition:: bullet list

|
||||
|
||||
|
||||
Definition list
|
||||
---------------
|
||||
|
||||
.. sidebar:: definition term
|
||||
|
||||
Note that the term cannot have more than one line of text.
|
||||
|
||||
Definition lists (:duref:`ref <definition-lists>`) are created as follows:
|
||||
|
||||
.. code:: reST
|
||||
|
||||
term (up to a line of text)
|
||||
Definition of the term, which must be indented
|
||||
|
||||
and can even consist of multiple paragraphs
|
||||
|
||||
next term
|
||||
Description.
|
||||
|
||||
.. admonition:: definition list
|
||||
:class: rst-example
|
||||
|

|

Definition of the term, which must be indented

||||
and can even consist of multiple paragraphs
|

next term
|

Description.
|
||||
|
||||
|
||||
Quoted paragraphs
|
||||
-----------------
|
||||
|
||||
Quoted paragraphs (:duref:`ref <block-quotes>`) are created by just indenting
|
||||
them more than the surrounding paragraphs. Line blocks (:duref:`ref
|
||||
<line-blocks>`) are a way of preserving line breaks:
|
||||
|
||||
.. code:: reST
|
||||
|
||||
normal paragraph ...
|
||||
lorem ipsum.
|
||||
|
||||
Quoted paragraph ...
|
||||
lorem ipsum.
|
||||
|
||||
| These lines are
|
||||
| broken exactly like in
|
||||
| the source file.
|
||||
|
||||
|

|

Field lists are used as part of an extension syntax, such as options for

directives, or database-like records meant for further processing. Field lists
|

are mappings from field names to field bodies. They marked up like this:
|
||||
|
