When we redraw the left sidebar, we need to tell the
topic list to clear its data structures (and do other
stuff like hiding its popover), since we are clearing
its parent container.
The commit f0e18b3b3e
introduced this regression in late January 2020.
That commit made topic_list use a vdom to avoid
unnecessary updates. Before that, topic_list did
a lot of brute-force redraws, which covered up the
fact that we weren't having stream_list telling it
when the rug was being pulled out from under it.
The boundary between stream_list and topic_list
has always been kind of complicated code, since
topic lists get embedded into the stream list.
The main interactions, though, are basically:
* topic_zoom.clear_topics() - you're leaving
a narrow that may or may not be zoomed
* topic_list.clear() - you're about to redraw
stream items in the unzoomed stream list
* topic_list.rebuild(stream_li, stream_id) -
you're building or updating a topic list
for the newly active stream

The _.each calls with an inline function expression have already been
converted to for…of loops. We could do that here, but using .forEach
when we’re just reusing an existing function seems like a good
guideline.

We avoid complicated code to update unread counts
by just using vdom.js.
One small change here is that if click on "more
topics", we replace it with the spinner instead
of putting the spinner after it. This saves us
a redraw under the new scheme.
This is relatively unobtrusive, and we don't send
anything to the server.
But any user can now enter blueslip.timings in the
console to see a map of how long things take in
milliseconds. We only record one timing per
event label (i.e. the most recent).
It's pretty easy to test this by just clicking
around. For 300 users/streams most things are
fast except for:
- initialize_everything
- manage streams (render_subscriptions)
Both do lots of nontrivial work, although
"manage streams" is a bit surprising, since
we're only measuring how long to build the
HTML from the templates (whereas the real
time is probably browser rendering costs).
The only thing get_color() does is look
up a sub:
exports.get_color = function (stream_name) {
const sub = exports.get_sub(stream_name);
if (sub === undefined) {
return stream_color.default_color;
}
return sub.color;
};
So if we have a sub already, there's no point
calling the helper.
Obviously, this isn't a huge deal, but it happens
N times during page load.
This avoids a stream having potentially near-infinite height when
opened in a stream with a large number of unread topics; the benefit
is that you can easily access the next stream.
We show an unread count next to "more topics" to make it hard to miss
that there might be more, older topics with unread messages.

This commit was originally automatically generated using `tools/lint
--only=eslint --fix`. It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

We have had a longtime bug where the state of pinned streams would not
update properly from the greyed out/inactive state to the active state
when a first message arrived to them.
After some discussion, we determined that likely the right fix for
this is to simply configure pinned streams to never be marked as
inactive; that's more in line with the intended user experience.
Fixes#8201.
perfect-scrollbar replaces both the appearance and the behavior of the
scrollbar, and its emulated behavior will never feel native on most
platforms. SimpleBar customizes the appearance while preserving the
native behavior.

This fixes an issue where closing stream search was not working if
user had not entered a search term and tried to close the search box
by clicking on the close icon; the problem was that we'd end up
re-opening the widget immediately after through event propagation.
Fixes: #11636.
We want the search widget, when visible, to be
outside the scroll container for the stream list.
One obvious use case is if you start scrolling, and
then realize it might be less effort to search.
Also, for user search, it already worked this way.
We have to add a couple resizing hooks here, but
it's not necessary to change the actual resize
calculation, since we move the section inside
of #streams_header, which is already accounted
for.
The only markup change here is to add
a `stream_search_section` class. I don't
know why we use `notdisplayed` here instead of
jQuery, or what `input-append` is for, but I
considered them outside the scope of this change.
We can also remove some crufty CSS that was
compensating for it being inside the container.
The stream_list test that was fixed here was sort of
broken. It accomplished the main goal of verifying
what gets rendered, but now the data setup part is
more like the actual app code (and simpler, too).
This small modules nicely breaks down the
responsibilities of topic_list and stream_list
when it comes to zooming in and out of topics
(also known as hitting "more topics" or "All
Streams).
Before this, neither module was clearly in
charge, and there were kind of complicated
callback mechanisms. The stream_list code
was asking topic_list to create click handlers
that called back into stream_list.
Now we just topic_zoom set up its own click
handlers and delegate out to the other two
modules.
This allows several modules to no longer need
to import `narrow` (or, in our current pre-import
world, to not have to use that global).
The broken dependencies are reflected in the node
tests, which should now run slightly faster.
Currently on zoom out from stream topics, scrollbar didn't scroll back
to opened stream. Because call to scroll-to-stream func isn't called
after all streams view is displayed. So wrong stream element is
passed to func.
Fix this by calling scroll-to-stream func after all-stream-list view
is displayed.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
This is preparation for enabling an eslint indentation configuration.
90% of these changes are just fixes for indentation errors that have
snuck into the codebase over the years; the others are more
significant reformatting to make eslint happy (that are not otherwise
actually improvements).
The one area that we do not attempt to work on here is the
"switch/case" indentation.
We don't need to special-case the stream cog handler when we
handle the click event for the surrounding header. The browser
will fire the event for the cog first, which stops propagation.
The new list_cursor class is more generic and saves the state
of your cursor across redraws.
Note that we no longer cycle from bottom to top or vice versa.
The node test code that was removed here was kind of complex
and didn't actually assert useful things after calling methods.
This introduces a generic class called list_cursor to handle the
main details of navigating the buddy list and wires it into
activity.js. It replaces some fairly complicated code that
was coupled to stream_list and used lots of jQuery.
The new code interacts with the buddy_list API instead of jQuery
directly. It also persists the key across redraws, so we don't
lose our place when a focus ping happens or we type more characters.
Note that we no longer cycle to the top when we hit the bottom, or
vice versa. Cycling can be kind of an anti-feature when you want to
just lay on the arrow keys until they hit the end.
The changes to stream_list.js here do not affect the left sidebar;
they only remove code that was used for the right sidebar.
We consistently either pass a `then_select_id` into narrow.activate,
or were using the select_first_unread option. Now, we just compute
select_first_unread based on the value of then_select_id.
When in the stream-searchbar, a user can now use the arrow keys to iterate
through the suggestions. Therefore the currently selected list element is
assigned a CSS class 'highlighted_user'.
The main functional testing is done with casper but node test are still
included to keep the high coverage.
Line-wrapping issues are resolved. Night-mode CSS handling is included.
