reST primer¶

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 github.io. For build prerequisites read Build docs.

The source files of Searx’s documentation are located at git://docs. Sphinx assumes source files to be encoded in UTF-8 by defaul. Run make docs-live to build HTML while editing.

Contents

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].

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 (git://docs) folder we have three sections (and the blog folder), each dedicate to a different group of audience.

User’s POV: git://docs/user: A typical user knows about search engines and might have heard about meta crawlers and privacy.
Admin’s POV: git://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: git://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). If the chronological order matters, describe it. Name the out-of-limits conditions and all the side effects a external developer will not know.

Basic inline markup ¶

Basic inline markup is done with asterisks and backquotes. If asterisks or backquotes appear in running text and could be confused with inline markup delimiters, they have to be escaped with a backslash (\*pointer).

Table 3 basic inline markup¶
description	rendered	markup
one asterisk for emphasis	italics	`italics`
two asterisks for strong emphasis	boldface	`boldface`
backquotes for code samples and literals	`foo()`	``foo()``
quote asterisks or backquotes	*foo is a pointer	`\*foo is a pointer`

Basic article structure ¶

The basic structure of an article makes use of heading adornments to markup chapter, sections and subsections.

reST template ¶

reST template for an simple article:

.. _doc refname:

==============
Document title
==============

Lorem ipsum dolor sit amet, consectetur adipisici elit ..  Further read
:ref:`chapter refname`.

.. _chapter refname:

Chapter
=======

Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut
aliquid ex ea commodi consequat ...

.. _section refname:

Section
-------

lorem ..

.. _subsection refname:

Subsection
~~~~~~~~~~

lorem ..

Headings ¶

title - with overline for document title:

==============
Document title
==============

chapter - with anchor named anchor name:
```
.. _anchor name:

Chapter
=======
```
section
```
Section
-------
```
subsection
```
Subsection
~~~~~~~~~~
```

Anchors & Links ¶

Anchors ¶

To refer a point in the documentation a anchor is needed. The 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:

.. _reST anchor:

Anchors
-------

To refer a point in the documentation a anchor is needed ...

To refer anchors use the ref role markup:

Visit chapter :ref:`reST anchor`.  Or set hyperlink text manualy :ref:`foo
bar <reST anchor>`.

:ref: role

Visist chapter Anchors. Or set hyperlink text manualy foo bar.

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:

.. _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>`__.

Named hyperlink

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.

Smart refs ¶

With the power of sphinx.ext.extlinks and intersphinx referencing external content becomes smart.

Table 4 smart refs with sphinx.ext.extlinks and intersphinx¶

Intersphinx is configured in git://docs/conf.py:

intersphinx_mapping = {
    "python": ("https://docs.python.org/3/", None),
    "flask": ("https://flask.palletsprojects.com/", None),
    "jinja": ("https://jinja.palletsprojects.com/", None),
    "linuxdoc" : ("https://return42.github.io/linuxdoc/", None),
    "sphinx" : ("https://www.sphinx-doc.org/en/master/", None),
}

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

$ python -m sphinx.ext.intersphinx https://docs.python.org/3/objects.inv

Literal blocks ¶

The simplest form of literal-blocks is a indented block introduced by two colons (::). For highlighting use highlight or code-block directive. To include literals from external files use directive literalinclude.

`::`¶

::

  Literal block

Lorem ipsum dolor::

  Literal block

Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy
eirmod tempor invidunt ut labore ::

  Literal block

`code-block`¶

The code-block directive is a variant of the code directive with additional options. To learn more about code literals visit Showing code examples.

The URL ``/stats`` handle is shown in :ref:`stats-handle`

.. code-block:: Python
   :caption: python code block
   :name: stats-handle

   @app.route('/stats', methods=['GET'])
   def stats():
       """Render engine statistics page."""
       stats = get_engines_stats()
       return render(
           'stats.html'
           , stats = stats )

Code block

The URL /stats handle is shown in python code block

Listing 2 python code block¶

@app.route('/stats', methods=['GET'])
def stats():
    """Render engine statistics page."""
    stats = get_engines_stats()
    return render(
        'stats.html'
        , stats = stats )

Unicode substitution ¶

The unicode directive converts Unicode character codes (numerical values) to characters. This directive can only be used within a substitution definition.

.. |copy| unicode:: 0xA9 .. copyright sign
.. |(TM)| unicode:: U+2122

Trademark |(TM)| and copyright |copy| glyphs.

Unicode

Roles ¶

A custom interpreted text role (ref) is an inline piece of explicit markup. It signifies that that the enclosed text should be interpreted in a specific way.

The general markup is one of:

:rolename:`ref-name`
:rolename:`ref text <ref-name>`

Table 5 smart refs with sphinx.ext.extlinks and intersphinx¶
role	rendered example	markup
`guilabel`	Cancel	:guilabel:`&Cancel`
`kbd`	`C-x C-f`	:kbd:`C-x C-f`

subscript	H₂O	H\ :sub:`2`\ O
superscript	E = mc²	E = mc\ :sup:`2`
title-reference	Time	:title:`Time`

Figures & Images ¶

Searx’s sphinx setup includes: Scalable figure and image handling. Scaleable here means; scaleable 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 Scalable figure and image handling 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 (inheritance of figure) and kernel-image (inheritance of image) directives. E.g. to insert a figure with a scaleable image format use SVG (Simple SVG image.):

.. _svg image example:

.. kernel-figure:: svg_image.svg
   :alt: SVG image example

   Simple SVG image

 To refer the figure, a caption block is needed: :ref:`svg image example`.

Fig. 2 Simple SVG image.¶

To refer the figure, a caption block is needed: Simple SVG image..

DOT files (aka Graphviz)¶

With kernel-figure & kernel-image reST support for DOT formatted files is given.

A simple example is shown in DOT’s hello world example:

.. _dot file example:

.. kernel-figure:: hello.dot
   :alt: hello world

   DOT's hello world example

hello.dot

Fig. 3 DOT’s hello world example¶

`kernel-render` DOT ¶

Embed render markups (or languages) like Graphviz’s DOT is provided by the kernel-render directive. A simple example of embedded DOT is shown in figure Embedded DOT (Graphviz) code:

.. _dot render example:

.. kernel-render:: DOT
   :alt: digraph
   :caption: Embedded  DOT (Graphviz) code

   digraph foo {
     "bar" -> "baz";
   }

Attribute ``caption`` is needed, if you want to refer the figure: :ref:`dot
render example`.

Please note build tools. If Graphviz is installed, you will see an vector image. If not, the raw markup is inserted as literal-block.

kernel-render DOT

Fig. 4 Embedded DOT (Graphviz) code¶

Attribute caption is needed, if you want to refer the figure: Embedded DOT (Graphviz) code.

`kernel-render` SVG ¶

A simple example of embedded SVG is shown in figure Embedded SVG markup:

.. _svg render example:

.. kernel-render:: SVG
   :caption: Embedded **SVG** markup
   :alt: so-nw-arrow

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" version="1.1"
     baseProfile="full" width="70px" height="40px"
     viewBox="0 0 700 400"
     >
  <line x1="180" y1="370"
        x2="500" y2="50"

        />
  <polygon points="585 0 525 25 585 50"
           transform="rotate(135 525 25)"
           />
</svg>

List markups ¶

Bullet list ¶

List markup (ref) is simple:

- 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.

bullet list

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.

Horizontal list ¶

The .. hlist:: transforms a bullet list into a more compact list.

.. hlist::

   - first list item
   - second list item
   - third list item
   ...

hlist

first list item
second list item
third list item
next list item

next list item xxxx
next list item yyyy
next list item zzzz

Definition list ¶

Each definition list (ref) item contains a term, optional classifiers and a definition. A term is a simple one-line word or phrase. Optional classifiers may follow the term on the same line, each after an inline ‘ : ‘ (space, colon, space). A definition is a block indented relative to the term, and may contain multiple paragraphs and other body elements. There may be no blank line between a term line and a definition block (this distinguishes definition lists from block quotes). Blank lines are required before the first and after the last definition list item, but are optional in-between.

Definition lists are created as follows:

term 1 (up to a line of text)
    Definition 1.

See the typo : this line is not a term!

  And this is not term's definition.  **There is a blank line** in between
  the line above and this paragraph.  That's why this paragraph is taken as
  **block quote** (:duref:`ref <block-quotes>`) and not as term's definition!

term 2
    Definition 2, paragraph 1.

    Definition 2, paragraph 2.

term 3 : classifier
    Definition 3.

term 4 : classifier one : classifier two
    Definition 4.

definition list

term 1 (up to a line of text): Definition 1.

See the typo : this line is not a term!

And this is not term’s definition. There is a blank line in between the line above and this paragraph. That’s why this paragraph is taken as block quote (ref) and not as term’s definition!

term 2

Definition 2, paragraph 1.

Definition 2, paragraph 2.

term 3classifier

Definition 3.

term 4 : classifier one : classifier two

Quoted paragraphs ¶

Quoted paragraphs (ref) are created by just indenting them more than the surrounding paragraphs. Line blocks (ref) are a way of preserving line breaks:

normal paragraph ...
lorem ipsum.

   Quoted paragraph ...
   lorem ipsum.

| These lines are
| broken exactly like in
| the source file.

Quoted paragraph and line block

normal paragraph … lorem ipsum.

Quoted paragraph … lorem ipsum.

These lines are
broken exactly like in
the source file.

Field Lists ¶

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:

:fieldname: Field content
:foo:       first paragraph in field foo

            second paragraph in field foo

:bar:       Field content

Field List

fieldname

Field content

foo

first paragraph in field foo

second paragraph in field foo

bar

Field content

They are commonly used in Python documentation:

def my_function(my_arg, my_other_arg):
    """A function just for me.

    :param my_arg: The first of my arguments.
    :param my_other_arg: The second of my arguments.

    :returns: A message (just for me, of course).
    """

Further list blocks ¶

field lists (ref, with caveats noted in Field Lists)
option lists (ref)
quoted literal blocks (ref)
doctest blocks (ref)

Admonitions ¶

Generic admonition ¶

The generic admonition needs a title:

.. admonition:: generic admonition title

   lorem ipsum ..

generic admonition title

lorem ipsum ..

Specific admonitions ¶

Specific admonitions: hint, note, tip attention, caution, danger, error, , important, and warning .

.. hint::

Tables ¶

ASCII-art tables like Simple tables and Grid tables might be comfortable for readers of the text-files, but they have huge disadvantages in the creation and modifying. First, they are hard to edit. Think about adding a row or a column to a ASCII-art table or adding a paragraph in a cell, it is a nightmare on big tables.

Second the diff of modifying ASCII-art tables is not meaningful, e.g. widening a cell generates a diff in which also changes are included, which are only ascribable to the ASCII-art. Anyway, if you prefer ASCII-art for any reason, here are some helpers:

Simple tables ¶

Simple tables allow colspan but not rowspan. If your table need some metadata (e.g. a title) you need to add the .. table:: directive (ref) in front and place the table in its body:

.. table:: foo gate truth table
   :widths: grid
   :align: left

   ====== ====== ======
       Inputs    Output
   ------------- ------
   A      B      A or B
   ====== ====== ======
   False
   --------------------
   True
   --------------------
   True   False  True
          (foo)
   ------ ------ ------
   False  True
          (foo)
   ====== =============

Simple ASCII table

Table 6 foo gate truth table¶
Inputs		Output
A	B	A or B
False
True
True	False (foo)	True
False	True (foo)

Grid tables ¶

Grid tables allow colspan colspan and rowspan:

.. table:: grid table example
   :widths: 1 1 5

   +------------+------------+-----------+
   | Header 1   | Header 2   | Header 3  |
   +============+============+===========+
   | body row 1 | column 2   | column 3  |
   +------------+------------+-----------+
   | body row 2 | Cells may span columns.|
   +------------+------------+-----------+
   | body row 3 | Cells may  | - Cells   |
   +------------+ span rows. | - contain |
   | body row 4 |            | - blocks. |
   +------------+------------+-----------+

ASCII grid table

Table 7 grid table example¶
Header 1	Header 2	Header 3
body row 1	column 2	column 3
body row 2	Cells may span columns.
body row 3	Cells may span rows.	Cells contain blocks.
body row 4	Cells may span rows.	Cells contain blocks.

flat-table ¶

The flat-table is a further developed variant of the list tables. It is a double-stage list similar to the list-table with some additional features:

column-span: cspan

with the role cspan a cell can be extended through additional columns

row-span: rspan

with the role rspan a cell can be extended through additional rows

auto-span:

spans rightmost cell of a table row over the missing cells on the right side of that table-row. With Option :fill-cells: this behavior can changed from auto span to auto fill, which automatically inserts (empty) cells instead of spanning the last cell.

options:

header-rows: [int] count of header rows
stub-columns: [int] count of stub columns
widths: [[int] [int] … ] widths of columns
fill-cells: instead of auto-span missing cells, insert missing cells

roles:

cspan: [int] additional columns (morecols)
rspan: [int] additional rows (morerows)

The example below shows how to use this markup. The first level of the staged list is the table-row. In the table-row there is only one markup allowed, the list of the cells in this table-row. Exception are comments ( .. ) and targets (e.g. a ref to row 2 of table’s body).

.. flat-table:: ``flat-table`` example
   :header-rows: 2
   :stub-columns: 1
   :widths: 1 1 1 1 2

   * - :rspan:`1` head / stub
     - :cspan:`3` head 1.1-4

   * - head 2.1
     - head 2.2
     - head 2.3
     - head 2.4

   * .. row body 1 / this is a comment

     - row 1
     - :rspan:`2` cell 1-3.1
     - cell 1.2
     - cell 1.3
     - cell 1.4

   * .. Comments and targets are allowed on *table-row* stage.
     .. _`row body 2`:

     - row 2
     - cell 2.2
     - :rspan:`1` :cspan:`1`
       cell 2.3 with a span over

       * col 3-4 &
       * row 2-3

   * - row 3
     - cell 3.2

   * - row 4
     - cell 4.1
     - cell 4.2
     - cell 4.3
     - cell 4.4

   * - row 5
     - cell 5.1 with automatic span to rigth end

   * - row 6
     - cell 6.1
     - ..

List table

Table 8 `flat-table` example¶
head / stub	head 1.1-4
head / stub	head 2.1	head 2.2	head 2.3	head 2.4
row 1	cell 1-3.1	cell 1.2	cell 1.3	cell 1.4
row 2		cell 2.2	cell 2.3 with a span over col 3-4 & row 2-3

row 4	cell 4.1	cell 4.2	cell 4.3	cell 4.4
row 5	cell 5.1 with automatic span to rigth end
row 6	cell 6.1

CSV table ¶

CSV table might be the choice if you want to include CSV-data from a outstanding (build) process into your documentation.

.. csv-table:: CSV table example
   :header: .. , Column 1, Column 2
   :widths: 2 5 5
   :stub-columns: 1
   :file: csv_table.txt

Content of file csv_table.txt:

stub col row 1, column, "loremLorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy
eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam
voluptua."
stub col row 1, "At vero eos et accusam et justo duo dolores et ea rebum. Stet clita
kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.", column
stub col row 1, column, column

CSV table

Table 9 CSV table example¶
	Column 1	Column 2
stub col row 1	column	loremLorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.
stub col row 1	At vero eos et accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet.	column
stub col row 1	column	column

Templating ¶

Templating is suitable for documentation which is created generic at the build time. The sphinx-jinja extension evaluates jinja templates in the build environment (with searx modules installed). We use this e.g. to build chapter: Engines. Below the jinja directive from the git://docs/admin/engines.rst is shown:

.. jinja:: webapp

   .. flat-table:: Engines configured at built time (defaults)
      :header-rows: 1
      :stub-columns: 2

      * - Name (cfg)
        - S
        - Engine
        - TO
        - Categories
        - P
        - L
        - SS
        - D
        - TR
        - O
	- W
	- D

      {% for name, mod in engines.items() %}

      * - {{name}}
        - !{{mod.shortcut}}
        - {{mod.__name__}}
        - {{mod.timeout}}
        - {{", ".join(mod.categories)}}
        - {{(mod.paging and "y") or ""}}
        - {{(mod.language_support and "y") or ""}}
        - {{(mod.safesearch and "y") or ""}}
        - {{(mod.disabled and "y") or ""}}
        - {{(mod.time_range_support and "y") or ""}}
        - {{(mod.offline and "y") or ""}}
        - {{mod.weight or 1 }}
        - {{(mod.disabled and "y") or ""}}

     {% endfor %}

The context for the template is selected in the line .. jinja:: webapp. In sphinx’s build configuration (git://docs/conf.py) the webapp context points to the name space of the python module: webapp.

from searx import webapp
jinja_contexts = {
    'webapp': dict(**webapp.__dict__)
}

Tabbed views ¶

With sphinx-tabs extension we have tabbed views. To provide installation instructions with one tab per distribution we use the group-tabs directive, others are basic-tabs and code-tabs. Below a group-tab example from Build docs is shown:

.. tabs::

   .. group-tab:: Ubuntu / debian

      .. code-block:: sh

         $ sudo apt install graphviz imagemagick texlive-xetex librsvg2-bin

   .. group-tab:: Arch Linux

      .. code-block:: sh

         $ sudo pacman -S graphviz imagemagick texlive-bin extra/librsvg

   .. group-tab::  Fedora / RHEL

      .. code-block:: sh

         $ sudo dnf install graphviz graphviz-gd texlive-xetex-bin librsvg2-tools

For PDF output you also need:

.. tabs::

   .. group-tab:: Ubuntu / debian

      .. code:: sh

         $ sudo apt texlive-latex-recommended texlive-extra-utils ttf-dejavu

   .. group-tab:: Arch Linux

      .. code:: sh

      	 $ sudo pacman -S texlive-core texlive-latexextra ttf-dejavu

   .. group-tab::  Fedora / RHEL

      .. code:: sh

      	 $ sudo dnf install \
	        texlive-collection-fontsrecommended texlive-collection-latex \
		dejavu-sans-fonts dejavu-serif-fonts dejavu-sans-mono-fonts

Math equations ¶

The input language for mathematics is LaTeX markup using the CTAN: amsmath package.

To embed LaTeX markup in reST documents, use role :math: for inline and directive .. math:: for block markup.

In :math:numref:`schroedinger general` the time-dependent Schrödinger equation
is shown.

.. math::
   :label: schroedinger general

    \mathrm{i}\hbar\dfrac{\partial}{\partial t} |\,\psi (t) \rangle =
          \hat{H} |\,\psi (t) \rangle.

LaTeX math equation

In (1) the time-dependent Schrödinger equation is shown.
