* [mod] client/simple: client plugins
Defines a new interface for client side *"plugins"* that coexist with server
side plugin system. Each plugin (e.g., `InfiniteScroll`) extends the base
`ts Plugin`. Client side plugins are independent and lazy‑loaded via `router.ts`
when their `load()` conditions are met. On each navigation request, all
applicable plugins are instanced.
Since these are client side plugins, we can only invoke them once DOM is fully
loaded. E.g. `Calculator` will not render a new `answer` block until fully
loaded and executed.
For some plugins, we might want to handle its availability in `settings.yml`
and toggle in UI, like we do for server side plugins. In that case, we extend
`py Plugin` instancing only the information and then checking client side if
[`settings.plugins`](1ad832b1dc/client/simple/src/js/toolkit.ts (L134))
array has the plugin id.

Previously, when using a search url copied from the cookies tab, clicking
at the settings icon at the top right would show the browser preferences
and not the preferences that were set and used with the search url.
Please see https://github.com/searxng/searxng/issues/5227 for more information.
To test:
- change some preferences
- copy the preferences search url in the settings' cookies tab
- reset the preferences or clear cookies
- paste the copied search url into the search bar to search for something
- press the settings icon
- you can now see/preview the actual settings that were used for the search
- by pressing 'save', you can keep these preferences

To avoid an `unsafe-inline` in the CSP header, the JS code must be moved to the
client side [1].
The `<script>` tag at the end of the HTML originates from the old implementation
of the JS client. Since PR-5073 [2] was merged, the `type` is now `module`, and
the tag must be moved to the beginning of the HTML.

That's true in theory, but in practice, this effect is unnoticeable because it's
masked by another effect (which we can't avoid): If we load the page with a
severely throttled connection, the HTML (result list) takes a long time to
load. Then the CSS is loaded, which also takes longer. Until the CSS has loaded,
there's no layout. A layout shift is therefore largely determined by the loading
of the HTML and CSS itself.
The running times of the ESM script can be neglected compared to the loading
times of HTML & CSS.

TypeScript is a superset of JavaScript, converting the entire theme to
TypeScript allows us to receive much more feedback on possible issues made in
package updates or our own typos, furthermore, it allows to transpile properly
to lower specs. This PR couldn't be done in smaller commits, a lot of work
needed to make everything *work properly*:
- A browser baseline has been set that requires minimum **Chromium 93, Firefox
92 and Safari 15** (proper visuals/operation on older browser versions is not
guaranteed)
- LightningCSS now handles minification and prefix creation for CSS.
- All hardcoded polyfills and support for previous browser baseline versions
have been removed.
- Convert codebase to TypeScript.
- Convert IIFE to ESM, handling globals with IIFE is cumbersome, ESM is the
standard for virtually any use of JS nowadays.
- Vite now builds the theme without the need for `vite-plugin-static-copy`.
- `searxng.ready` now accepts an array of conditions for the callback to be
executed.
- Replace `leaflet` with `ol` as there were some issues with proper Vite
bundling.
- Merged `head` with `main` script, as head was too small now.
- Add `assertElement` to properly check the existence of critical DOM elements.
- `searxng.on` renamed to `searxng.listen` with some handling improvements.
This patch implements the template generation of the template:
searx/templates/simple/icons.html
by the way the icon set (the icon names) has been normalized:
film-outline --> film
magnet-outline --> magnet
..
warning --> alert
Some missing (categorie) icons had been added.
Some of the ionicons are not suitable for a dark theme, we fixed the svg
manually in src/svg/ionicons:

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.
- https://github.com/searxng/searxng/issues/357
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).
!en-de dog
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.

Some administrators may want to hide the link to public_instances: If you run a
private instance for a company that wants there employees to use the private
instance instead of any of the public instances.
Add a new setting: general.donation_url
By default the value is https://docs.searxng.org/donate.html
When the value is false, the link is hidden
When the value is true, the link goes to the infopage donation,
the administrator can create a custom page.
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 the preferences & stats templates contained the markup:
<a href="{{ url_for('index') }}"><h1><span>SearXNG</span></h1></a>
There are many things wrong with this:
1. the markup was duplicated
2. the CSS needed to be changed whenever a new page wanted to use this
header (since the CSS used page-specific selectors)
3. h1 should be reserved for the actual page title
(e.g. Preferences or Engine stats)
4. the image was set via CSS which also set:
span { visibility: hidden; }
which however removes the alternative text from the accessibility
tree (meaning screen readers will ignore it).
This commit fixes all these problems.
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...)
In the templates and the /config (JSON) the usage of the 'brand.*' name
space is replaced by 'searx.get_setting' function.
- new_issue_url --> get_setting('brand.new_issue_url')
- brand.GIT_URL --> get_setting('brand.git_url')
- brand.PUBLIC_INSTANCES --> get_setting('brand.public_instances')
- brand.DOCS_URL --> get_setting('brand.docs_url')
- brand.ISSUE_URL --> get_setting('brand.issue_url')
- brand.CONTACT_URL --> get_setting('general.contact_url', '')
The macro 'new_issue' from searx/templates/*/messages/no_results.html
is now imported with context::
{% from '__common__/new_issue.html' import new_issue with context %}
To get *public instances URL* from context's 'get_setting()' function::
get_setting('brand.public_instances','')
Macro's prototype does no longer need the 'new_issue_url' argument and has been
changed to::
macro new_issue(engine_name, engine_reliability)
