We had a handful of methods attached to the root `Discourse` object
related to focus and notification counts.
This patch pulls them out into a service called `document-title` for
updating the title, and a component called `d-document` to attach
and listen for browser events related to focus.
It also removes some computed properties and observers in favor of plain
old Javascript objects.
`topicTrackingState.forEachTracked(topic,isNew,isUnread)` can be used to
iterate through tracking state efficiently.
This is handy for extension looking at subsets of tags and categories.
Uses a thin border as indicator that element is in focus for all editable items in the composer (inputs, select kit, textarea).
Disables a default iOS style that has a blinking background color on inputs/textareas
After visiting a topic list (by tag / category / top level) we track the list
Once a list is tracked the combo `g` `j` can be used to go to the next topic
in the list and `g` `k` to go to previous topic.
This allows you to quickly work through subsets of topics without having
to navigate back to the top level lists
The shortcut does not work in PM lists yet, or search results, both are
under consideration.
This `description` field on a theme is returned from the server side and
needn't be calculated in the front end. I tested in the UX and seems to
work well.
(This change could be considered a little risky so we should keep an eye
on it.)
The core issue here is that sometimes as far as the router was concerned
we had transitioned to a route even if a Topic model was still in the
process of loading. In this case the callback could not retrieve the
correct title yet because it had not loaded.
This fix returns a promise from `setupController` when visiting a topic,
which will have the router block until the topic is loaded. This means
that the transition never triggers until the topic title is present.
Note: adding a test for this is basically impossible - it was super hard
to reproduce even in a browser.
This code was intended to bypass iterating through tags in absence of a new
or unread topic.
Instead it always fired cause it was checking for function existence which
was clearly always true.
This involves a little refactoring of how our `defaultHomepage()` works.
It previously would check the meta tag / site settings each time it was
called but now it only checks once on application boot.
Since `Discourse.SiteSettings` is removed, helpers can now include and
call `helperContext().siteSettings` to get access to the settings
without using a global variable.
