Adds description in views styled like stream descriptions also adds a
help center link to the appropriate page at the end of each
description.
Fixes#29769.
Reproducer:
* Go to a stream narrow.
* Scroll up to select a previous message.
* Click on a different stream in the left sidebar.
* Click browser back button, you land at first unread message instead
of your selected message.
Fixed by updating the hash before we render the new message list.
In 61b3c698af we stopped restoring widgets
from the cache, so the only purpose of the cache remaining was to access
the event handler patched onto the widget jquery.
Now instead of the entire jquery object, we cache just the event handler
since that's the only thing we need from the cache, and do not patch it
onto the widget jquery object.
When compose box is expanded, typeahead overlfows the top of the window.
We move the typeahead to the bottom of the screen and let
preventOverflow shift it into the visible area.
Earlier we did not activate widgets if their rendered HTML was cached,
and also when narrowing to the combined feed view. This caused bugs with
widgets not being activated, and so not responding to any interactions.
Now we unconditionally render and activate widgets in the current view,
irrespective of the cached HTML or the view being narrowed to.
This is no longer required since narrow state is restored by
`reload` library and narrow history restores the narrow pointer
and offset when going back to a view.
Only regression here is we will no longer restore the pointer when
user navigates to the combined feed view without using browser back
button and combined feed view is the default view. This is fixed
in the next commit.
For onboarding banners, we replace the close button with
"Got it" button.
Also, the banner is marked as read for the user only after
the "Got it" button is clicked. Earlier it was marked as read
as soon as it was displayed.
Register our `onTextInputHook` to be called on "input" events so that
the hook receives the updated text content of the input unlike the "keydown"
event which does not update the text content before running the hook.
Updates the base hash for the streams setting overlay to be
"channels" instead of "streams".
Because there are Welcome Bot and Notification Bot messages that
would have been sent with the "/#streams" hash, we will need to
support parsing those overlay hashes as an alias for "/#channels"
permanently.
Part of the stream to channels rename project.
Additionally, the text colors have been updated for both light and dark
themes, it starts showing when 900 or less characters are left, as 999
was too soon, and has a tooltip to show the maximum characters limit.
Fixes: #28706.
Add a rule to the switch_rows(event) function to avoid
switching stream row when pressing up/down key by checking
the current URL hash and the add_subscribers_pill focus state.
Add a utility function to hash_parser to help implement new
switch_rows behavior mentioned above.
Fixes#29690.
Important changes in this commit:
* We only cache message list for "Combined feed" if it is the
default view.
* We modify existing handling of home message list code so that
it can be used to for any message list that we want to cache
using a new `preserve_rendered_state` variable.
* narrow_state.filter() returns the filter of combined feed view list
instead of `undefined`.
* We start fetching messages from the latest message on app load.
* Messages in all messages data and Recent view are always synced.
* If combined feed view list is not cached, we don't track it's
last pointer, effectively sending user to the latest unread
message always .
Updates the logic for adding a wildcard mention syntax in a message
to use the "channel" wildcard instead of the "stream" wildcard.
Adds some TODO notes for eventually removing the "stream" wildcard
from the typeahead suggestions in the web app.
Part of stream to channel rename project.
Updates operators used for narrow.activate and sent as narrow
parameters to the server to use channel and channels.
Part of stream to channel rename project.
Updates the search suggestions in the web app to use the modern
convention of "channel" and "channels".
Also, updates the "from" search suggestions to use the modern
canonical convention of "sender".
