Change styling of filter input & remove button.
This follows the same pattern of design we use for search. In the search dropdown we do not have a button to search. We rely on pressing enter. I've also provided an example of Github's PR filter UI at the bottom of this comment.
We also do not have buttons like this on any other topic-list header. On tag and category dropdowns, we also rely on pressing enter to filter the topic list by chosen categories & tags.

Using the unitless number 0 in CSS calc() functions is recognized as invalid (tested in Chrome 110 & Firefox 111).
In this code, this would disable the style definition for the 'height' property when one of the custom properties is undefined and the fallback '0' is used.
For more insight on this topic. see https://stackoverflow.com/questions/55406001/why-doesnt-css-calc-work-when-using-0-inside-the-equation
Popper dropdowns used `position: fixed` or `position: absolute`. But in
tables, we want the content to use auto overflow horizontally, and that
causes the dropdowns to be hidden vertically in some scenarios.
Setting a containing block on the parent container fixes both placement
and overflow issues.
Tested with Chrome <100, Firefox <100 and Samsung Internet 20, using
percentage-based height here works better for these browsers.
This was especially a problem for the Samsung Internet browser, because
it previously was hiding the "Dismiss" button on the user profile menu.

The new hashtags render with an `<svg>` element inside a `<a>`
tag, which is an icon to indicate the "type" of the hashtag.
In Firefox, this was disrupting both triple-click text selection
and simple dragging cursor text selection. The selection would
stop at the SVG rather than continuing past it. This works fine
in Chrome -- either Chrome is not doing the right thing or Firefox
is.
Either way the issue is fixed by simply making the `svg` an inline
element inside the link, which it should be anyway.
Using Javascript to read and recalculate sizing is prone to causing 'forced reflows', which are very expensive, especially on slower devices. This PR refactors the slide-in menus so that all of the height calculation is done using CSS. This is made possible by the new dvh (dynamic view height) units and env(safe-area-inset-bottom), both of which are supported on all of our target browsers.
In tests on a moto g50, on a sidebar with 16 categories, 15 tags, and 2 chat channels, this improves the sidebar opening time by around 50ms (6%).

**This PR creates a new core reusable component wraps a character counter around any input.**
The component accepts the arguments: `max` (the maximum character limit), `value` (the value of text to be monitored).
It can be used for example, like so:
```hbs
<CharCounter @max="50" @value={{this.charCounterContent}}>
<textarea
placeholder={{i18n "styleguide.sections.char_counter.placeholder"}}
{{on "input" (action (mut this.charCounterContent) value="target.value")}}
class="styleguide--char-counter"></textarea>
</CharCounter>
```
**This PR also:**
1. Applies this component to the chat plugins edit channel's *Edit Description** modal, thereby replacing the simple text area which provided no visual indication when text exceeded the max allowed characters.
2. Adds an example to the `/styleguide` route
* UX: handle long userstatus in menupanel
* UX: remove margin on userstatus emoji
* UX: change emoji sise of user status in DM creator
* FIX: user status overflow on chat index
Before that change, footer of the sidebar was not visible.
Footer is very important, especially now, when add custom section button is located there.
Also, distance between chat input and keyboard were increased
Improvements for this PR: https://github.com/discourse/discourse/pull/20057
What was fixed:
- [x] Use ember transitions instead of full reload
- [x] Link was inaccurately kept active
- [x] "+ save" renamed to just "save"
- [x] Render emojis in link name
- [x] UI to set icon
- [x] Delete link is trash icon instead of "x"
- [x] Add another link to on the left and rewording
- [x] Raname "link name" -> "name", "points to" -> link
- [x] Add limits to fields
- [x] Move add section button to the bottom
This PR is a major change to Sass compilation in Discourse.

From:
- sassc 2.0.1 (Feb 2019)
- libsass 3.5.2 (May 2018)
To:
- dart-sass 1.58

Allows users to configure their own custom sidebar sections with links withing Discourse instance. Links can be passed as relative path, for example "/tags" or full URL.
Only path is saved in DB, so when Discourse domain is changed, links will be still valid.
Feature is hidden behind SiteSetting.enable_custom_sidebar_sections. This hidden setting determines the group which members have access to this new feature.
We've had a couple of problems with the R2 gem where it generated a broken RTL CSS bundle that caused a badly broken layout when Discourse is used in an RTL language, see a3ce93b and 5926386. For this reason, we're replacing R2 with `rtlcss` that can handle modern CSS features better than R2 does.
`rltcss` is written in JS and available as an npm package. Calling the `rltcss` from rubyland is done via the `rtlcss_wrapper` gem which contains a distributable copy of the `rtlcss` package and loads/calls it with Mini Racer. See https://github.com/discourse/rtlcss_wrapper for more details.
Internal topic: t/76263.
Behavior should be very similar but the code is simplified and it should fix various bugs where the card was showing out of screen even if we had available space.
This replaces the position declared as `#123` with the more simple version `123`.
The property position may be of type Integer or Text. A value of type Integer, or more precise of type Text which simply casts to integer, is sufficient here.
See: https://schema.org/position
In category-view the topic-list already uses this notation for the position of topics:
`<meta itemprop="position" content="123">`
Meta topic: https://meta.discourse.org/t/android-keyboard-overlaps-text-when-flagging-with-something-else/249687?u=osama
On Android, it's currently not possible to scroll modals that take input from the user (such as the flagging modal) when the keyboard is open which means that the keyboard can cover up part of the modal with no way for the user to see the covered part without closing the keyboard. This commit adds some CSS to make these modals scrollable when the keyboard is open.
Currently when generating a onebox for Discourse topics, some important
context is missing such as categories and tags.
This patch addresses this issue by introducing a new onebox engine
dedicated to display this information when available. Indeed to get this
new information, categories and tags are exposed in the topic metadata
as opengraph tags.

This PR adds a new "Pause notifications" checkbox to the user status modal. This checkbox allows enabling the Do-Not-Disturb mode together with user status. Note that we don't remove and don't rename the existing DnD menu item in this PR, so the old way of entering the DnD mode is still available.
Also, we're not making DnD mode a part of user status on backend and in database. The reason is that the DnD mode should still be available on sites with disabled user status, having them separated helps keep the implementation simple.
1. The events table had broken styling, making each row overflow
2. It had confusing routes: `/:id` for "edit" and `/:id/events` for "show" (now it's `/:id/edit` and `/:id` respectively)

This prevents long inbox names from causing issues in the dropdown on /my/messages and tries a new mobile layout that makes better use of the available space:
In this PR, we introduced an option, that when all authenticators are disabled, but backup codes still exists, user can authenticate with those backup codes. This was reverted as this is not expected behavior.
https://github.com/discourse/discourse/pull/18982
Instead, when the last authenticator is deleted, backup codes should be deleted as well. Because this disables 2fa, user is asked to confirm that action by typing text.
In addition, UI for 2fa preferences was refreshed.
In an effort to modernize our codebase to the latest Ember version we have selected the Topic Timeline as a candidate to be refactored. The topic timeline component was originally built with `Widgets` and this PR will upgrade it to `Glimmer Components`.
The refactored timeline is hidden by default behind a group flag, `SiteSetting.enable_experimental_topic_timeline_groups`. Being part of a group included in this site setting will make the new timeline available for testing.
## Other points of interest
This PR introduces a `Draggable Modifier` available to all components, which will take the place of the existing _drag functionality_ exclusive to widgets.
It can be included like so:
```
{{draggable didStartDrag=@didStartDrag didEndDrag=@didEndDrag dragMove=@dragMove }}
```
This PR adds separate notification indicators for PMs and reviewables that have arrived since the last time the user opened the notifications menu.
The PM indicator is the strongest one of all three indicators followed by the reviewable indicator and then finally the blue indicator. This means that if there's a new PM and a new reviewable, then the PM indicator will be shown.

* Do not search category name when searching channels to avoid
confusing results
* Overflow text in autocomplete menu with ... if it is too long
* Make autocomplete menu less height
This changes the hashtag search to first do a lookup to find
results where the slug exactly matches the
search term. Now when we search for hashtags, the
exact matches will be found first and put at the top of
the results.
`ChatChannelFetcher` has also been modified here to allow
for more options for performance -- we do not need to
query DM channels for secured IDs when looking up or searching
channels for hashtags, since they should never show in
results there (they have no slugs). Nor do we need to include
the channel archive records.
Also changes the limit of hashtag results to 20 by default
with a hidden site setting, and makes it so the scroll for the
results is overflowed.
While updating all user pages to use the new horizontal, scrollable user
page navigation, we've inadvertently broken the interface for plugins which rely on the
`user-main-nav` plugin outlet to extend the user profile page. Such
plugins usually add a new user profile page with the following
template structure which is copied from Discourse core before the user
page navigation redesign:
```
{{#d-section pageClass="..." class="user-secondary-navigation" scrollTop=false}}
{{#mobile-nav class="..." desktopClass="action-list nav-stacked"}}
...
{{/mobile-nav}}
{{/d-section}}
<section class="user-content">
{{outlet}}
</section>
```
This commit seeks to add backwards compatibility in terms of the styling
of the interface such that even if the old template structure is used,
it would not look completely broken.
This commit unescapes the :emoji: and expands into
an image within hashtag autocomplete results, and
also makes some style tweaks to make sure the emoji
is not too big.
This fix changes the hashtag-raw hashtags, which are
the ones that do not actually match anything, back
to the old style which does not look like mentions.
The user preferences tracking page is only present when the redesign
user navigation menu is enabled. During the first pass of
implementation, some old bugs were introduced and this commit fixes
that. Regression tests have also been added.
This commit fleshes out and adds functionality for the new `#hashtag` search and
lookup system, still hidden behind the `enable_experimental_hashtag_autocomplete`
feature flag.
**Serverside**
We have two plugin API registration methods that are used to define data sources
(`register_hashtag_data_source`) and hashtag result type priorities depending on
the context (`register_hashtag_type_in_context`). Reading the comments in plugin.rb
should make it clear what these are doing. Reading the `HashtagAutocompleteService`
in full will likely help a lot as well.
Each data source is responsible for providing its own **lookup** and **search**
method that returns hashtag results based on the arguments provided. For example,
the category hashtag data source has to take into account parent categories and
how they relate, and each data source has to define their own icon to use for the
hashtag, and so on.
The `Site` serializer has two new attributes that source data from `HashtagAutocompleteService`.
There is `hashtag_icons` that is just a simple array of all the different icons that
can be used for allowlisting in our markdown pipeline, and there is `hashtag_context_configurations`
that is used to store the type priority orders for each registered context.
When sending emails, we cannot render the SVG icons for hashtags, so
we need to change the HTML hashtags to the normal `#hashtag` text.
**Markdown**
The `hashtag-autocomplete.js` file is where I have added the new `hashtag-autocomplete`
markdown rule, and like all of our rules this is used to cook the raw text on both the clientside
and on the serverside using MiniRacer. Only on the server side do we actually reach out to
the database with the `hashtagLookup` function, on the clientside we just render a plainer
version of the hashtag HTML. Only in the composer preview do we do further lookups based
on this.
This rule is the first one (that I can find) that uses the `currentUser` based on a passed
in `user_id` for guardian checks in markdown rendering code. This is the `last_editor_id`
for both the post and chat message. In some cases we need to cook without a user present,
so the `Discourse.system_user` is used in this case.
**Chat Channels**
This also contains the changes required for chat so that chat channels can be used
as a data source for hashtag searches and lookups. This data source will only be
used when `enable_experimental_hashtag_autocomplete` is `true`, so we don't have
to worry about channel results suddenly turning up.
------
**Known Rough Edges**
- Onebox excerpts will not render the icon svg/use tags, I plan to address that in a follow up PR
- Selecting a hashtag + pressing the Quote button will result in weird behaviour, I plan to address that in a follow up PR
- Mixed hashtag contexts for hashtags without a type suffix will not work correctly, e.g. #ux which is both a category and a channel slug will resolve to a category when used inside a post or within a [chat] transcript in that post. Users can get around this manually by adding the correct suffix, for example ::channel. We may get to this at some point in future
- Icons will not show for the hashtags in emails since SVG support is so terrible in email (this is not likely to be resolved, but still noting for posterity)
- Additional refinements and review fixes wil
Trying out changes to reduce the number of nav items in the experimental horizontal user nav. These changes should only appear with the redesigned_user_page_nav_enabled feature flag.
1. Created a new "Tracking" route. This combines some tracking-related settings from Notifications and Category and Tag tracking (which were separate tabs previously). Don't love the layout yet, but it's something that we can work on.
2. Moved some user-related settings out of Notifications and to the
Users tab. These seem more user-related to me, and it's nice that we can
associate enabling messages with the setting to limit who can send
messages.
3. Moved the App tab (lists app permissions) to be within the Security tab. It's very similar to Recently Used Devices.

Previously if a specific plugin route was not available (e.g. there was an error loading the plugin's JS due to an ad blocker), the entire page would fail to load. This commit updates the behavior to catch this kind of issue and display a user-friendly message at the top of the screen.
This commit adds a new `/hashtag/search` endpoint and both
relevant JS and ruby plugin APIs to handle plugins adding their
own data sources and priority orders for types of things to search
when `#` is pressed.
A `context` param is added to `setupHashtagAutocomplete` which
a corresponding chat PR https://github.com/discourse/discourse-chat/pull/1302
will now use.
The UI calls `registerHashtagSearchParam` for each context that will
require a `#` search (e.g. the topic composer), for each type of record that
the context needs to search for, as well as a priority order for that type. Core
uses this call to add the `category` and `tag` data sources to the topic composer.
The `register_hashtag_data_source` ruby plugin API call is for plugins to
add a new data source for the hashtag searching endpoint, e.g. discourse-chat
may add a `channel` data source.
This functionality is hidden behind the `enable_experimental_hashtag_autocomplete`
flag, except for the change to `setupHashtagAutocomplete` since only core and
discourse-chat are using that function. Note this PR does **not** include required
changes for hashtag lookup or new styling.
This commit introduces a new framework for building user tutorials as
popups using the Tippy JS library. Currently, the new framework is used
to replace the old notification spotlight and tips and show a new one
related to the topic timeline.
All popups follow the same structure and have a title, a description and
two buttons for either dismissing just the current tip or all of them
at once.
The state of all seen popups is stored in a user option. Updating
skip_new_user_tips will automatically update the list of seen popups
accordingly.
The lint warnings were:
```
inline-block is ignored due to the float. If 'float' has a value other than 'none', the box is floated and 'display' is treated as 'block'
scss(propertyIgnoredDueToDisplay)
```
Adds a new upload field for a second dark mode category logo.
This alternative will be used when the browser is in dark mode (similar to the global site setting for a dark logo).
Prior to this fix pressing tab multiple times in the sidebar, you would end up focusing invisible "sidebar-section-header-button". This change ensures the button will become visible when tabbing even if not hovering this section.
The `background: transparent change` is to avoid a flashing background due to different transition timing on the collapsable button.
This commit introduces an icon to all links in the sidebar. If an icon has not been configured, we will fall back to a generic "link" icon. As part of this commit, we also standardised the size of each prefix to 20px by 20px and set a fix margin. This is to allow sufficient space for text prefixes and image prefixes to be displayed.
Tests have been intentionally left out for now as I don't feel like asserting for the icons will bring much value at this point. Time shall prove me wrong.

* FIX: Better virtual keyboard detect on Android
Firefox has a bug where *sometimes* the visualViewport.height won't be
updated when the keyboard pops up until you scroll, making our composer
stay hidden behind the keyboard. This commit uses both window.innerHeight
and window.visualViewport.height using the minimum of both to check for
height changes.
For Chrome/Edge we feature detect the new VirtualKeyboard API and
opt-into it when the composer opens and use it to detect if a keyboard
is being draw. Opting into the API changes how the viewport is
calculated so we have to also change how the full height composer is
calculated. To minimize breakage we opt-out when the composer component
is destroyed.
This commit also moves the `--composer-ipad-padding` to only happen on
iPads.

This commits introduces a new SiteSetting.enable_new_user_profile_nav_groups
feature flag. When configured, users of the configured groups will see
the new user page navigation links.
As of this commit, only the user activity navigation link has been
converted to the newly proposed dropdown of navigation links.
Mobile support has not been considered.
Previously we were calculating both the minimum and maximum widths for
SK dropdowns using this Popper modifier. The max. width calculation was
causing issues with dropdowns in Firefox and was also sluggish when
rendering.
This switches to using CSS calculations for max. widths. It adds a 600px
global maximum and targeted maximums for the category composer dropdown
and the bookmark list dropdowns.
This commit includes various accessibility improvements for the new user menu:
* Add `title` attributes to the user menu tabs
* Properly label lists (by adding `aria-labelledby` to `<ul>` elements) for screen readers
* Change the user menu structure so that the tabs come before the content panel in the DOM, but use CSS to reverse them visually.
Normally, changing the order of elements via CSS is bad for accessibility, but I believe this is one of the rare scenarios where it [makes sense](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Flexible_Box_Layout/Ordering_Flex_Items#use_cases_for_order). Prior to this change, if you want to reach the first notification item after you select a tab using the keyboard, you have to hit <kbd>ctrl</kbd>+<kbd>tab</kbd> because the notifications list is before the tabs list. However, with this change, <kbd>tab</kbd> will move you to the first item in the list after you select a tab using your keyboard.
* Aria-hide the unread notifications badge/count on the tabs because the `title` attribute on the tab indicates the unread count.
* Add some tests.
