**TL;DR:** Refactor autocomplete to use async markdown parsing for code block detection.
Previously, the `inCodeBlock` function in `discourse/app/lib/utilities.js` used regular expressions to determine if a given position in the text was inside a code block. This approach had some limitations and could lead to incorrect behavior in certain edge cases.
This commit refactors `inCodeBlock` to use a more robust algorithm that leverages Discourse's markdown parsing library.
The new approach works as follows:
1. Check if the text contains any code block markers using a regular expression.
If not, return `false` since the cursor can't be in a code block.
1. If potential code blocks exist, find a unique marker character that doesn't appear in the text.
1. Insert the unique marker character into the text at the cursor position.
1. Parse the modified text using Discourse's markdown parser, which converts the markdown into a tree of tokens.
1. Traverse the token tree to find the token that contains the unique marker character.
1. Check if the token's type is one of the types representing code blocks ("code_inline", "code_block", or "fence").
If so, return `true`, indicating that the cursor is inside a code block.
Otherwise, return `false`.
This algorithm provides a more accurate way to determine the cursor's position in relation to code blocks, accounting for the various ways code blocks can be represented in markdown.
To accommodate this change, the autocomplete `triggerRule` option is now an async function.
The autocomplete logic in `composer-editor.js`, `d-editor.js`, and `hashtag-autocomplete.js` has been updated to handle the async nature of `inCodeBlock`.
Additionally, many of the tests have been refactored to handle async behavior. The test helpers now simulate typing and autocomplete selection in a more realistic, step-by-step manner. This should make the tests more robust and reflective of real-world usage.
This is a significant refactor that touches multiple parts of the codebase, but it should lead to more accurate and reliable autocomplete behavior, especially when dealing with code blocks in the editor.

Changing an `@tracked` value in a `willDestroyElement` hook will not immediately trigger a re-render. Instead, it seems to update on the next natural runloop iteration, which may be significantly later depending on what else is happening.
Instead, these kinds of 'data' changes should be made based on the lifecycle of the component instance (init / willDestroy). Making changes to tracked properties here does seem to cause immediate invalidation & re-render.
On mobile, when viewing the My Threads area, each thread will show:
- The avatar of the last responder in the thread, overlaid with the chat thread symbol to visually distinguish this area from DMs.
- Either the thread title, where applicable, or the first message of the thread, truncated to fit on one line.
- The channel where the thread originated.
- The last message sent in the thread, truncated to fit on one line.
- When the last message was sent in the thread.

There are a couple of reasons for this.
The first one is practical, and related to eager loading. Since /lib is not eager loaded, when the application boots, ProblemCheck["identifier"] will be nil because the child classes aren't loaded.
The second one is more conceptual. There turns out to be a lot of inter-dependencies between the part of the problem check system that live in /app and the parts that live in /lib, which probably suggests it should all go in /app.
* Bump the moment-timezone version in package.json
* update yarn lock
* bump moment
* bin/rails javascript:update
* npx yarn-deduplicate
* update the spec (not sure which tz changed exactly but there's a 1 hour difference now for year 2018 and earlier 🤷♂️)

Why this change?
On the `/admin/customize/themes/<:id>` route, we allow admins to edit
all settings via a settings editor. Prior to this change, trying to edit
and save a typed objects theme settings will result in an error on the
server.
Why this change?
On a slow network, using the `AceEditor` component will result in a blob
of text being shown first before being swapped out with the `ace.js`
editor after it has completed loading.
There is also a problem when setting the theme for the editor which
would result in a "flash" as reported in
https://github.com/ajaxorg/ace/issues/3286. To avoid this, we need to
load the theme js file before displaying the editor.
What does this change do?
1. Adds a loading spinner and set the `div.ace` with a `.hidden` class.
2. Once all the relevant scripts and initialization is done, we will
then remove the loading spinner and remove `div.ace`.
This change creates a user setting that they can toggle if
they don't want to receive unread notifications when someone closes a
topic they have read and are watching/tracking it.
* A11Y: Update bulk selection keyboard shortcuts
Still a draft, but in current state this:
- adds `shift+b` as a keyboard shortcut to toggle bulk select
- adds `shift+d` as a keyboard shortcut to dismiss selected topic(s) (this
replaces `x r` and `x t` shortcuts)
- adds `x` as a keyboard shortcut to toggle selection (while in bulk select mode)
- fixes a bug with the `shift+a` shortcut, which was not working properly
Note that there is a breaking change here. Previously we had:
- `x r` to dismiss new topics
- `x t` to dismiss unread topics
However, this meant that we couldn't use `x` for selection, because the
itsatrap library does not allow the same character to be used both as a
single character shortcut and as the start of a sequence. The proposed
solution here is more consistent with other apps (Gmail, Github) that use
`x` to toggle selection.
Also, we never show both "Dismiss New" and "Dismiss Unread" in the same
screen, hence it makes sense to consolidate both actions under `shift+d`.
* Address review
- The thread preview is now a regular link and can be right clicked
- left gutter date, and regular date of a thread message will not correctly link to the thread's message
Why this change?
Before this change, the new navigation item in the topic list will be
hidden when there are no new or unread topics for the user. We have
started to find this behaviour confusing UX wise so we decided to stop
hiding it.
Why this change?
This is a regression from introduced in
5c1147adf3339c89a3ccb69839b4a4c5fd75a2ab where dismissing unread topics
was changing the notification level of the topics instead of just
dismissing the unread posts.
What does this change do?
1. Bring back the previous implementation of the action
2. Fix the system test that was supposed to catch the problem but did
not.
The `home-logo-wrapper` outlet is used by chat, which means it is unavailable for use by any other themes/plugins. This commit introduces a second nested outlet called `home-logo` which can be used to replace the logo without affecting chat's header logic.
This commit improves the "+ X subcategories" option that shows sometimes
in the category selector. It used to show when there was a single match,
but now it also shows up on exact matches even though there are multiple
results.
It also makes it work when lazy_load_categories is enabled by searching
the subcategories before rendering them.
This commit fixes two issues:
1. The wrong exception was being printed as the 'cause' in turbo_rspec output. This was happening because RSpec [expects exceptions to be subclasses of `Exception`](d6e320dc11/lib/rspec/core/formatters/exception_presenter.rb (L102)). This commit resolves the issue by replacing the `FakeException` `Struct` with a subclass of `Exception`.
2. The `full_cause_backtrace` option we set in `rails_helper.rb` does not carry through to the RSpec formatters running in the turbo_rspec reporter process. To fix that, this commit duplicates the necessary config in `lib/turbo_tests.rb`.
Example before - note that the cause is a duplicate of the original exception, and only has three lines of backtrace:
