This is often used by gadgets/scripts to request
information from the API. Given `vector` means old Vector
now that leads to styling issues.
The unfortunate side effect of this is that any code
checking mw.config('skin') === 'vector' will no longer work
and we'll likely need to patch various gadgets accordingly.

Hooks::isSkinLegacy is only checking the skin version
but not the skin name. This is likely why we are seeing
errors due a mismatch between the result of Hooks::isSkinLegacy
and SkinVector::isLegacy
The parameter is made optional as it is not
always needed. For example in the onGetPreferences
method the skin hasn't been set at this point so all
we need to do is check the skin version.

Vector has a wgVectorResponsive flag. This adds a ResourceLoader
module as well
I propose the configuration is repurposed to disable the min-width
on Vector and enable the viewport tag. This will allow us to use
test.wikipedia.org to test Vector at lower resolutions in future
as well as provide a suitable option for 3rd parties wanting to run
a responsive version of Vector that can be opted into using:
```
$wgVectorResponsive = true;
$wgVectorDefaultSkinVersion = '2';
```
As part of this change, the default skin version is set to 2, in
preparation for the next MediaWiki release. Note on Wikimedia wikis we
explicitly set this version so this will not impact any of our deployed

Creates a new skins.vector.search module that
replaces the searchSuggest module from MediaWiki core.
This module creates a new Vue app using the WVUI
search widget for the new search experience.
The legacy search input form is still retains on pageload,
and the new search kicks on search input focus.
In order to manage that transition, the legacy search
input is styled to resemble the new WVUI input, and the
new input is manually focused after the component mounts.
Vue is also added as a dev-dependency to help with
type-checking.

I177dad88 introduced the skin version user preference field and
associated configuration values. Per T242381, the field is to presented
as a checkbox with the implied storage type of a boolean where a string
is needed. A PreferencesFormPreSave hook handler was added to adapt
values of either data type to the other. While this was a neat solution
to a minor nit, the adapter's implementation is incompatible with the
GlobalPreferences extension as the PreferencesFormPreSave hook isn't run
whilst saving global preferences.
Rather than adding an equivalent hook to the GlobalPreferences
extension, create a custom field based on a checkbox with the adapter
included. This allows us to:
- Separate the business logic concerned with preserving the user's
VectorSkinVersion preference if they've simply disabled Vector from
the adapter
- Simplify the adapter's implementation
- Forego adding hooks to the GlobalPreferences codebase
Additional changes:
- Replace repeated string literals with equivalent constants in

To support roll out and avoid issues with cached HTML the new

the body tag has `skin-vector-search-header` class.
For legacy mode, we introduce a new class
`skin-vector-search-header-legacy` and temporarily use a CSS3 `:not()`
selector to ensure the styles ship during the phase where cached
HTML can be served. While this will create some display issues in
browsers that do not support CSS3 selectors, all grade A browsers in

Please note I7e06a4cc226f3434c0f655212a464b8b98bcc7f4 should be
merged at the same time as this patch.
== The background ==
All extensions have been weaned of BaseTemplate hooks in
Wikimedia projects.
This change now means that Vector will no longer run
any BaseTemplate hooks. See the epic T253809 for the
implementation details.
== The change ==
BaseTemplate will now have nothing to do with the rendering of
Vector. The skin version is added to express the significance of
breaking compatibility with 3rd party extensions.
We TEMPORARILY remove SkinVector to retain git blame. SkinTemplateVector will
be renamed SkinVector in the follow up (see 2/2)
Update skin.json to use SkinTemplateVector for the skin (this will be fixed
in a follow up).
The isLegacy method is moved to SkinTemplateVector.
Changes of note:
* html-debuglog is no longer needed. SkinMustache includes this information on
the skins behalf
* html-printtail and html-headelement are now not needed in the master template
and added by SkinMustache
* Skin::getAfterPortlet does not provide the `after-portlet` wrapping element provided
by BaseTemplate::getAfterPortlet so this is added
* SkinTemplate::getFooterIcons does not support the options that BaseTemplate::getFooterIcons
does so any icons which do not have an image must be manually checked for and unset
Known changes to HTML output as a result of intentionally
delegating their output to the core SkinMustache class:
* A new line is removed between the body element and #mw-page-base
* #mw-html-debug-log now appears at the end of the body element
* #printfooter is now a child of #mw-content-text rather than sibling.

This patch closely follows the desired guidelines/desired
styles Alex Hollender has put forth in his prototype, but uses
multiple containers to achieve this look since our DOM order/structure
is different than the DOM structure in the prototype. The following
containers are used, but unlike his prototype, they are sometimes used
more than once:
* Page Container: Contains every other container and limits the overall
max-width of the white part of the page.
* Workspace Container: Contains the sidebar and content container. The
sidebar is displaced ~30 pixels to the start (left) of the workspace
container at all times.
* Content Container: Contains the content. The max-width of this changes
depending on whether you are on a special page/history page vs. other
pages.
* Article Toolbar Container: Contains the article toolbar. The max-width
of this is always the same as the max-width of the article content as we
don't want the toolbar to move when going from the article page to the
history/special page.
Changes to be aware:
* To test locally, `$wgVectorLayoutMaxWidth = true;`. This design is
temporarily feature flagged and defaults to being "off".
* Note that layout-max-width.less is a temporary file made to meet the
feature flag requirement of T246420 (intended to derisk the deployment).
After the deploy, we should merge most if not all of the rules into
layout.less where the max-width design will become the default.
* Per Jon's code review comment, I have relaxed the indenting of
skin.mustache to make the diff easier to reason about. If desired, the
correct indenting can be achieved in a (much less risky) follow-up
commit.

and its documentation.
Unfortunately, user sessions are unavailable in
`Hooks::onUserGetDefaultOptions()` so it does not seem to be possible to
determine whether the active user is an anonymous or existing account.
This patch drops the hook and centralizes all version determination
logic in SkinVersionLookup::getVersion(). SkinVersionLookup requires a
the active User object and can make the anonymous / existing account
determination by checking login state.

Sections can be nested. Using rendering/skin as the parent
means that Vector's skin preference will always come straight
after the skin preference and before Popups.
A change in core is needed to update the selector for the element which
shows/hides the subsection as well as provide a generic message key to
replace the one inside this repository.
Note: If the "Vector" specific heading is needed, we can achieve this
with a little more work but that is a conversation for another time.

Add a Vector-specific user preference to Special:Preferences for
toggling skin version, either Legacy Vector or the latest Vector.
The presentation of the new preference section and the default values
for anonymous, new, and existing accounts are configurable via
$wgVectorShowSkinPreferences, $wgVectorDefaultSkinVersion (to be used by
the feature manager in T244481),
$wgVectorDefaultSkinVersionForExistingAccounts, and
$wgVectorDefaultSkinVersionForNewAccounts. These configurations default
to the fullest experience so that third-party configuration is minimal.
See skin.json for details. The configurations are each tested in
VectorHooksTest.php.
When presentation is enabled, the new preference appears as a checkbox;
enabled is Legacy mode and disable is latest. There are a number of
unfortunate details:
- Showing and hiding a checkbox is supported by OOUI. Showing and hiding
a whole section (Vector skin preferences, in this case) is not so this
additional client JavaScript functionality is added in Core (see
Iaf68b238a8ac7a4fb22b9ef5d6c5a3394ee2e377).
- Stylization as a checkbox is wanted. However, the implied storage type
for OOUI checkboxes is a boolean. This is not wanted in the event that
another skin version is added (e.g., '3' or 'alpha'). As a workaround,
the preference is converted from a boolean to a version string ('1' or
'2') on save in Hooks::onPreferencesFormPreSave() and from a version
string to a checkbox enable / disable string ('1' or '0') in
onGetPreferences(). There a number of test cases to help cover these
concerning details.
Documentation for overriding the skin version as a URL query parameter
is provided in anticipation of T244481.
