Don't focus on search box when user is at end or start of
the table and is using vim keys. This ends up being a
bad UX as once user is inside the search box, vim
navigation keys cannot be used to take user out of
the search box.
TextField is used to allow users to set long stream + topic narrow
names in the urls.
We currently restrict users to only set "all_messages" and
"recent_topics" as narrows.
This commit achieves 3 things:
* Removes recent topics as the default view which loads when
hash is empty.
* Loads default_view when hash is empty.
* Loads default_view on pressing escape key when it is unhandled by
other present UI elements.
NOTE: After this commit loading zulip with an empty hash will
automatically set hash to default_view. Ideally, we'd just display
the default view without a hash, but that involves extra complexity.
One exception is when user is trying to load an overlay directly,
i.e. zulip is loaded with an overlay hash. In this case,
we render recent topics is background irrespective of default_view.
We consider this last detail to be a bug not important enough to block
adding this setting.
When user presses escape but there is no action that recent topics
can perform on it, it returns false.
The final state of focus is the focus on topics table. If the focus
is on table and not on RT search or filters, we return false to
indicate that the key was unhandled by recent topics.
This will allow escape to take user to another view if recent topics
is not the default view.
The top row of the RT can be hidden sometimes after scrolling down
and then scrolling up. This is because the focus is applied before
the row is rendered. Applying the focus after the topic row is
rendered by the browser makes sure it is always visisble when
it needs to be.
For inputs to recent topics which were unhandled, we return false
so that the browser can handle them.
This also fixes the issue of search box not able input `t` key.
We land user on the first row of the table instead of the search
box because here user can access hotkeys like `w`, `q`, `/`, etc,
which will not be directly available if user is focused in
recent topics search box.
For tests:
We set focus to search by default to avoid mocking a lot of
table html for getting the tests passing.
Previously the filter would be reset every time the page was
refreshed. This commit adds persistence via localstorage, the tests
follow the pattern used in tests for drafts.
Fixes: #15676.
Go to Recent Topics on "#", no hash and "#recent_topics".
Go to Recent Topics as the last destination for escape key.
Map `a` key to All messages and change its hash to
`#all_messages`.
Recent Topics is no longer an overlay now, but note that it is
also not a typical messages narrow. It can reside between
an overlay and a Filter in the sense that it is dispalyed as
a typical Filter narrow but has properties of an Overlay.
Compose box is not visible in this view as it will be confusing
to many users and hence compose shortcuts have also been disabled.
Keyboard shortcuts that apply on messages have also been disabled.
The remaining shortcuts that apply to a narrow are still accessible
here.
Instead of prohibiting ‘return undefined’ (#8669), we require that a
function must return an explicit value always or never. This prevents
you from forgetting to return a value in some cases. It will also be
important for TypeScript, which distinguishes between undefined and
void.
