Markus Heiser 5720844fcd [doc] rearranges Settings & Engines docs for better readability
We have built up detailed documentation of the *settings* and the *engines* over
the past few years.  However, this documentation was still spread over various
chapters and was difficult to navigate in its entirety.

This patch rearranges the Settings & Engines documentation for better
readability.

To review new ordered docs::

   make docs.clean docs.live

.. _makefile:
========
Makefile
========
.. _gnu-make: https://www.gnu.org/software/make/manual/make.html#Introduction
.. sidebar:: build environment
Before looking deeper at the targets, first read about :ref:`make
install`.
To install system requirements follow :ref:`buildhosts`.
All relevant build tasks are implemented in :origin:`manage` and for CI or
IDE integration a small ``Makefile`` wrapper is available. If you are not
familiar with Makefiles, we recommend to read gnu-make_ introduction.
The usage is simple, just type ``make {target-name}`` to *build* a target.
Calling the ``help`` target gives a first overview (``make help``):
.. program-output:: bash -c "cd ..; make --no-print-directory help"
.. contents::
:depth: 2
:local:
:backlinks: entry
.. _make install:
Python environment (``make install``)
=====================================
.. sidebar:: activate environment
``source ./local/py3/bin/activate``
We do no longer need to build up the virtualenv manually. Jump into your git
working tree and release a ``make install`` to get a virtualenv with a
*developer install* of SearXNG (:origin:`setup.py`). ::
$ cd ~/searxng-clone
$ make install
PYENV [virtualenv] installing ./requirements*.txt into local/py3
...
PYENV OK
PYENV [install] pip install -e 'searx[test]'
...
Successfully installed argparse-1.4.0 searx
BUILDENV INFO:searx:load the default settings from ./searx/settings.yml
BUILDENV INFO:searx:Initialisation done
BUILDENV build utils/brand.env
If you release ``make install`` multiple times the installation will only
rebuild if the sha256 sum of the *requirement files* fails. With other words:
the check fails if you edit the requirements listed in
:origin:`requirements-dev.txt` and :origin:`requirements.txt`). ::
$ make install
PYENV OK
PYENV [virtualenv] requirements.sha256 failed
[virtualenv] - 6cea6eb6def9e14a18bf32f8a3e... ./requirements-dev.txt
[virtualenv] - 471efef6c73558e391c3adb35f4... ./requirements.txt
...
PYENV [virtualenv] installing ./requirements*.txt into local/py3
...
PYENV OK
PYENV [install] pip install -e 'searx[test]'
...
Successfully installed argparse-1.4.0 searx
BUILDENV INFO:searx:load the default settings from ./searx/settings.yml
BUILDENV INFO:searx:Initialisation done
BUILDENV build utils/brand.env
.. sidebar:: drop environment
To get rid of the existing environment before re-build use :ref:`clean target
<make clean>` first.
If you think, something goes wrong with your ./local environment or you change
the :origin:`setup.py` file, you have to call :ref:`make clean`.
.. _make buildenv:
``make buildenv``
=================
Rebuild instance's environment with the modified settings from the
:ref:`settings brand` and :ref:`settings server` section of your
:ref:`settings.yml <settings location>`.
What is the :origin:`utils/brand.env` needed for and why do you need to rebuild
it if necessary?
Short answer: :ref:`installation and maintenance <searxng maintenance>`
scripts are running outside of instance's runtime environment and need some
values defined in the runtime environment.
All the SearXNG setups are centralized in the :ref:`settings.yml` file. This
setup is available as long we are in a *installed instance*. E.g. the
*installed instance* on the server or the *installed developer instance* at
``./local`` (the later one is created by a :ref:`make install <make install>` or
:ref:`make run <make run>`).
Tasks running outside of an *installed instance*, especially :ref:`installation
and maintenance <searxng maintenance>` tasks running at (pre-) installation time
do not have access to the SearXNG setup (from a *installed instance*). Those
tasks need a *build environment*.
The ``make buildenv`` target will update the *build environment* in:
- :origin:`utils/brand.env`
Tasks running outside of an *installed instance*, need the following settings
from the YAML configuration:
- ``SEARXNG_URL`` from :ref:`server.base_url <settings server>` (aka
``PUBLIC_URL``)
- ``SEARXNG_BIND_ADDRESS`` from :ref:`server.bind_address <settings server>`
- ``SEARXNG_PORT`` from :ref:`server.port <settings server>`
The ``GIT_URL`` and ``GIT_BRANCH`` in the origin:`utils/brand.env` file, are
readed from the git VCS and the branch that is checked out when ``make
buildenv`` command runs.
.. _brand:
**I would like to create my own brand, how should I proceed?**
Create a remote branch (``example.org``), checkout the remote branch (on your
local developer desktop) and in the :origin:`searx/settings.yml` file in the
:ref:`settings server` section set ``base_url``. Run ``make buildenv`` and
create a commit for your brand.
On your server you clone the branch (``example.org``) into your HOME folder
``~`` from where you run the :ref:`installation <installation>` and
:ref:`maintenance <searxng maintenance>` task.
To upgrade you brand, rebase on SearXNG's master branch (on your local
developer desktop), force push it to your remote branch. Go to your server, do
a force pull and run :ref:`sudo -H ./utils/searxng.sh instance update <update
searxng>`.
.. _make node.env:
Node.js environment (``make node.env``)
=======================================
.. _Node.js: https://nodejs.org/
.. _nvm: https://github.com/nvm-sh
.. _npm: https://www.npmjs.com/
.. jinja:: searx
Node.js_ version {{version.node}} or higher is required to build the themes.
If the requirement is not met, the build chain uses nvm_ (Node Version
Manager) to install latest LTS of Node.js_ locally: there is no need to
install nvm_ or npm_ on your system.
Use ``make nvm.status`` to get the current status of you Node.js_ and nvm_ setup.
Here is the output you will typically get on a Ubuntu 20.04 system which serves
only a `no longer active <https://nodejs.org/en/about/releases/>`_ Release
`Node.js v10.19.0 <https://packages.ubuntu.com/focal/nodejs>`_.
::
$ make nvm.status
INFO: Node.js is installed at /usr/bin/node
INFO: Node.js is version v10.19.0
WARN: minimal Node.js version is 16.13.0
INFO: npm is installed at /usr/bin/npm
INFO: npm is version 6.14.4
WARN: NVM is not installed
INFO: to install NVM and Node.js (LTS) use: manage nvm install --lts
To install you can also use :ref:`make nvm.nodejs`
.. _make nvm.nodejs:
``make nvm.nodejs``
===================
Install latest Node.js_ LTS locally (uses nvm_)::
$ make nvm.nodejs
INFO: install (update) NVM at /share/searxng/.nvm
INFO: clone: https://github.com/nvm-sh/nvm.git
...
Downloading and installing node v16.13.0...

INFO: Node.js is version v16.13.0
INFO: npm is installed at searxng/.nvm/versions/node/v16.13.0/bin/npm
INFO: npm is version 8.1.0
INFO: NVM is installed at searxng/.nvm
.. _make run:
``make run``
============
To get up a running a developer instance simply call ``make run``. This enables
*debug* option in :origin:`searx/settings.yml`, starts a ``./searx/webapp.py``
instance and opens the URL in your favorite WEB browser (:man:`xdg-open`)::
$ make run
Changes to theme's HTML templates (jinja2) are instant. Changes to the CSS & JS
sources of the theme need to be rebuild. You can do that by running::
$ make themes.all
Alternatively to ``themes.all`` you can run *live builds* of the theme you are
modify::
$ LIVE_THEME=simple make run
.. _make clean:
``make clean``
==============
Drops all intermediate files, all builds, but keep sources untouched. Before
calling ``make clean`` stop all processes using the :ref:`make install` or
:ref:`make node.env`. ::
$ make clean
CLEAN pyenv
PYENV [virtualenv] drop local/py3
CLEAN docs -- build/docs dist/docs
CLEAN themes -- locally installed npm dependencies
...
CLEAN test stuff
CLEAN common files
.. _make docs:
``make docs docs.autobuild docs.clean``
=======================================
We describe the usage of the ``doc.*`` targets in the :ref:`How to contribute /
Documentation <contrib docs>` section. If you want to edit the documentation
read our :ref:`make docs.live` section. If you are working in your own brand,
adjust your :ref:`settings brand`.
.. _make docs.gh-pages:
``make docs.gh-pages``
======================
To deploy on github.io first adjust your :ref:`settings brand`. For any
further read :ref:`deploy on github.io`.
.. _make test:
``make test``
=============
Runs a series of tests: :ref:`make test.pylint`, ``test.pep8``, ``test.unit``
and ``test.robot``. You can run tests selective, e.g.::
$ make test.pep8 test.unit test.sh
TEST test.pep8 OK
...
TEST test.unit OK
...
TEST test.sh OK
.. _make test.shell:
``make test.shell``
===================
:ref:`sh lint` / if you have changed some bash scripting run this test before
commit.
.. _make test.pylint:
``make test.pylint``
====================
.. _Pylint: https://www.pylint.org/
Pylint_ is known as one of the best source-code, bug and quality checker for the
Python programming language. The pylint profile used in the SearXNG project is
found in project's root folder :origin:`.pylintrc`.
.. _make search.checker:
``search.checker.{engine name}``
================================
To check all engines::
make search.checker
To check a engine with whitespace in the name like *google news* replace space
by underline::
make search.checker.google_news
To see HTTP requests and more use SEARXNG_DEBUG::
make SEARXNG_DEBUG=1 search.checker.google_news
.. _3xx: https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#3xx_redirection
To filter out HTTP redirects (3xx_)::
make SEARXNG_DEBUG=1 search.checker.google_news | grep -A1 "HTTP/1.1\" 3[0-9][0-9]"
...
