Typification of SearXNG
=======================
This patch introduces the typing of the results. The why and how is described
in the documentation, please generate the documentation ..
$ make docs.clean docs.live
and read the following articles in the "Developer documentation":
- result types --> http://0.0.0.0:8000/dev/result_types/index.html
The result types are available from the `searx.result_types` module. The
following have been implemented so far:
- base result type: `searx.result_type.Result`
--> http://0.0.0.0:8000/dev/result_types/base_result.html
- answer results
--> http://0.0.0.0:8000/dev/result_types/answer.html
including the type for translations (inspired by #3925). For all other
types (which still need to be set up in subsequent PRs), template documentation
has been created for the transition period.
Doc of the fields used in Templates
===================================
The template documentation is the basis for the typing and is the first complete
documentation of the results (needed for engine development). It is the
"working paper" (the plan) with which further typifications can be implemented
in subsequent PRs.

Answer Templates
================
With the new (sub) types for `Answer`, the templates for the answers have also
been revised, `Translation` are now displayed with collapsible entries (inspired
by #3925).

Plugins & Answerer
==================
The implementation for `Plugin` and `Answer` has been revised, see
documentation:
- Plugin: http://0.0.0.0:8000/dev/plugins/index.html
- Answerer: http://0.0.0.0:8000/dev/answerers/index.html
With `AnswerStorage` and `AnswerStorage` to manage those items (in follow up
PRs, `ArticleStorage`, `InfoStorage` and .. will be implemented)
Autocomplete
============
The autocompletion had a bug where the results from `Answer` had not been shown
in the past. To test activate autocompletion and try search terms for which we
have answerers
- statistics: type `min 1 2 3` .. in the completion list you should find an
entry like `[de] min(1, 2, 3) = 1`
- random: type `random uuid` .. in the completion list, the first item is a
random UUID
Extended Types
==============
SearXNG extends e.g. the request and response types of flask and httpx, a module
has been set up for type extensions:
- Extended Types
--> http://0.0.0.0:8000/dev/extended_types.html
Unit-Tests
==========
The unit tests have been completely revised. In the previous implementation,
the runtime (the global variables such as `searx.settings`) was not initialized
before each test, so the runtime environment with which a test ran was always
determined by the tests that ran before it. This was also the reason why we
sometimes had to observe non-deterministic errors in the tests in the past:
- https://github.com/searxng/searxng/issues/2988 is one example for the Runtime
issues, with non-deterministic behavior ..
- https://github.com/searxng/searxng/pull/3650
- https://github.com/searxng/searxng/pull/3654
- https://github.com/searxng/searxng/pull/3642#issuecomment-2226884469
- https://github.com/searxng/searxng/pull/3746#issuecomment-2300965005
Why msgspec.Struct
==================
We have already discussed typing based on e.g. `TypeDict` or `dataclass` in the past:
- https://github.com/searxng/searxng/pull/1562/files
- https://gist.github.com/dalf/972eb05e7a9bee161487132a7de244d2
- https://github.com/searxng/searxng/pull/1412/files
- https://github.com/searxng/searxng/pull/1356
In my opinion, TypeDict is unsuitable because the objects are still dictionaries
and not instances of classes / the `dataclass` are classes but ...
The `msgspec.Struct` combine the advantages of typing, runtime behaviour and
also offer the option of (fast) serializing (incl. type check) the objects.
Currently not possible but conceivable with `msgspec`: Outsourcing the engines
into separate processes, what possibilities this opens up in the future is left
to the imagination!
Internally, we have already defined that it is desirable to decouple the
development of the engines from the development of the SearXNG core / The
serialization of the `Result` objects is a prerequisite for this.
HINT: The threads listed above were the template for this PR, even though the
implementation here is based on msgspec. They should also be an inspiration for
the following PRs of typification, as the models and implementations can provide
a good direction.
Why just one commit?
====================
I tried to create several (thematically separated) commits, but gave up at some
point ... there are too many things to tackle at once / The comprehensibility of
the commits would not be improved by a thematic separation. On the contrary, we
would have to make multiple changes at the same places and the goal of a change
would be vaguely recognizable in the fog of the commits.

All favicons implementations have been documented and moved to the Python
package:
searx.favicons
There is a configuration (based on Pydantic) for the favicons and all its
components:
searx.favicons.config
A solution for caching favicons has been implemented:
searx.favicon.cache
If the favicon is already in the cache, the returned URL is a data URL [1]
(something like `data:image/png;base64,...`). By generating a data url from
the FaviconCache, additional HTTP roundtripps via the favicon_proxy are saved:
favicons.proxy.favicon_url
The favicon proxy service now sets a HTTP header "Cache-Control: max-age=...":
favicons.proxy.favicon_proxy
The resolvers now also provide the mime type (data, mime):
searx.favicon.resolvers

In the past, some files were tested with the standard profile, others with a
profile in which most of the messages were switched off ... some files were not
checked at all.
- ``PYLINT_SEARXNG_DISABLE_OPTION`` has been abolished
- the distinction ``# lint: pylint`` is no longer necessary
- the pylint tasks have been reduced from three to two
1. ./searx/engines -> lint engines with additional builtins
2. ./searx ./searxng_extra ./tests -> lint all other python files

This patch was inspired by the discussion around PR-2882 [2]. The goals of this
patch are:
1. Convert plugin searx.plugin.limiter to normal code [1]
2. isolation of botdetection from the limiter [2]
3. searx/{tools => botdetection}/config.py and drop searx.tools
4. in URL /config, 'limiter.enabled' is true only if the limiter is really
enabled (Redis is available).
This patch moves all the code that belongs to botdetection into namespace
searx.botdetection and code that belongs to limiter is placed in namespace
searx.limiter.
Tthe limiter used to be a plugin at some point botdetection was added, it was
not a plugin. The modularization of these two components was long overdue.
With the clear modularization, the documentation could then also be organized
according to the architecture.

To test:
- check the app works without the limiter, check `/config`
- check the app works with the limiter and with the token, check `/config`
- make docs.live .. and read

Implementations of the *traits* of the engines.
Engine's traits are fetched from the origin engine and stored in a JSON file in
the *data folder*. Most often traits are languages and region codes and their
mapping from SearXNG's representation to the representation in the origin search
engine.
To load traits from the persistence::
searx.enginelib.traits.EngineTraitsMap.from_data()
For new traits new properties can be added to the class::
searx.enginelib.traits.EngineTraits
.. hint::
Implementation is downward compatible to the deprecated *supported_languages
method* from the vintage implementation.
The vintage code is tagged as *deprecated* an can be removed when all engines
has been ported to the *traits method*.

There are several reasons why we should prefer markdown-it-py over mistletoe:
- Get identical rendering results in SearXNG's `/info` pages and the SearXNG's
project documentation which is build by Sphinx-doc.
In the Sphinx-doc we use the MyST parser to render Markdown and the MyST
parser itself is built on top of the markdown-it-py package.
- markdown-it-py has a typographer that supports *replacements*
and *smartquotes* (e.g. em-dash, copyright, ellipsis, ...) [1]
- markdown-it-py is much more flexible compared to mistletoe [2]
- markdown-it-py is the fastest CommonMark compliant parser in python [3]

This patch implements a bolierplate to share content from info-pages of the
SearXNG instance (URL /info) with the project documentation (path /docs/user).
The info pages are using Markdown (CommonMark), to include them in the project
documentation (reST) the myst-parser [1] is used in the Sphinx-doc build chain.
If base_url is known (defined in settings.yml) links to the instance are also
inserted into the project documentation::

Previously all categories were displayed as search engine tabs.
This commit changes that so that only the categories listed under
categories_as_tabs in settings.yml are displayed.
This lets us introduce more categories without cluttering up the UI.
Categories not displayed as tabs can still be searched with !bangs.
Previously the documentation grouped the engines by their first
category so e.g. YouTube and Invidious were only shown in the
in the videos section but not in the music section.
This commit fixes this by iterating over searx.engines.categories,
which also has the added benefit that the sections are now in the
same order as the tabs in the user interface.
* move `searx/static/themes/simple/img/searxng.svg` to `src/brand/searxng.svg`
* README.rst can use it without a reference to a theme.
* the simple theme can create `searx/static/themes/simple/img/searxng.png` using
the svg2png task

This commit remove the need to update the brand for GIT_URL and GIT_BRANCH:
there are read from the git repository.
It is possible to call python -m searx.version freeze to freeze the current version.
Useful when the code is installed outside git (distro package, docker, etc...)
Added function searx.get_setting(name, default=_unset):
Returns the value to which ``name`` point. If there is no such name in the
settings and the ``default`` is unset, a KeyError exception is raised.
In all the python processes ..
- make docs
- make buildenv
- make install (setup.py)
the usage of the 'brand.*' name space is replaced by 'searx.get_setting'
function.
- brand.SEARX_URL --> get_setting('server.base_url')
- brand.GIT_URL --> get_setting('brand.git_url')
- brand.GIT_BRANCH' --> get_setting('server.base_url')
- brand.ISSUE_URL --> get_setting('brand.issue_url')
- brand.DOCS_URL --> get_setting('brand.docs_url')
- brand.PUBLIC_INSTANCES --> get_setting('brand.public_instances')
- brand.CONTACT_URL --> get_setting('general.contact_url', '')
- brand.WIKI_URL --> get_setting('brand.wiki_url')
- brand.TWITTER_URL --> get_setting('brand.twitter_url', '')

Before this commit, in the documentation, the jinja context is 'webapp' and contains
the global variable in the searx.webapp module.
This commit changes this to include only the mandatory variables to build the
documentation.
