This is sort of a temporary fix to bring the state back to how it
was in commit: ef4337edcb. However,
long-term we will need to fix our local echo feature to do merging
of names just like we do on backend.
We don't need to get sorted streams in the "source"
function for typeahead, since we sort them later,
and we don't need to recalculate values.
This preserves the behavior that we include
unsubscribed streams in the typeahead, which is
probably intentional.
This pulls the essential bucketing/sorting logic out
of filter_table().
The diff isn't quite as clean as I'd like, but some
of the code that got added back to filter_table() can be
eliminated in the future. Basically, all the stuff
related to hidden ids can just be zapped if we go
to an approach of just re-building the DOM cleanly
whenever our filters change.
We replace two calls to stream_matches_query() with
a single call to triage_stream(), which prevents us
from doing the same is-subscribed checks twice.
We probably should have done this a while ago, even
though these functions are pretty tiny. The goal here
is to make it easier to have more consistent search
semantics.
Our first use case is subs.js. In this case we
are able to decouple a bit of generic string
matching from the subs-specific code.
We move some data code from subs.js to stream_data.js.
It's not clear we have been using the optimal sort for
dealing with locales, but this change preserves the
current behavior. The only subtle change here is that
we look up subs using a Dict now instead of a plain
JS object.
The values of this dictionary used to be raw DOM elements,
but get_row() wraps them again, so there's not a huge
reason to store them as raw DOM elements internally. It
is slightly easier to reason about the code if everything
stays at the jQuery level.
To preserve the old behavior here, we have to do something
that is kind of ugly, but at least it's explicit now. In
the old code, our cache was DOM elements, and if an id
wasn't in the cache, we would sneakily return $(undefined)
with this code in get_row():
return $(this._rows[id]);
And it turns out that $(undefined) is basically just a
zero-element jQuery object. A lot of our code depends
on this behavior and just works around the zero-element
objects as needed with checks like this:
if (this.selected_row()).length === 0) {
// don't try to get offset
}
For now we just preserve this behavior. We could eventually
be more strict here, or at least have aggressive warnings
on cache misses, but we'd need to retrofit code to be
able to call something like `has_rendered_selection()`
and/or deal with `undefined` as the return value for the case
where the selection hasn't been rendered.
Here is some example code that would cause tracebacks if
we just returned `undefined` for cache misses:
rerender_preserving_scrolltop: function () {
// old_offset is the number of pixels between the top of the
// viewable window and the selected message
var old_offset;
var selected_row = this.selected_row();
var selected_in_view = selected_row.length > 0;
if (selected_in_view) {
old_offset = selected_row.offset().top;
}
return this.rerender_with_target_scrolltop(selected_row,
old_offset);
},
This function is more cohesive and always takes in
a jQuery object containing exactly one DOM element,
and it does all stuff at the jQuery level of
abstraction (no raw DOM).
It's a pretty simple extraction--removing the level
of indentation makes the diff a bit noisy.
We shorten the name of the function and avoid having
all the callers call `.get()`. Now we mostly stay
in jQuery "space", which avoids some confusion about
when we're dealing with raw DOM elements and which
will facilitate unit testing.
Changed search pill padding, `.navbar-search` flex-wrap to match with
the CSS refactoring in 66df4e3e84.
The `height: 100%` changes to `.navbar-search` and `.input-append`
make up for the issue in which the pills overflowed in the mobile
view due to `.navbar-search` height being declared 40px explicitly
while the actual heiight in mobile view was shorter.
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.
We use these new functions in the message compose typeahead so that they
can also be used in a PM recipients typeahead with both people and user
groups.
We now render the "skin" part of "Stream Settings" before
adding in the actual streams. The new function
populate_stream_settings_left_panel() takes care of adding
the streams. It uses a new template called
`subscriptions.handlebars`.
Splitting out this function will give us more flexibility
for various improvements.
First, we can decide to render the list after we open the
overlay, just to avoid the problem that users don't know why
the modal's opening. (And we could add a loader spinner as
needed.)
Second, we can improve our filter features so that we do
filtering in the data instead of moving DOM rows around,
which is expensive.
Third, we can eventually introduce progressive rendering.
Finally, having the function broken out will make profiling
more precise about where bottlenecks exist.
Fixes#10059.
In 66df4e3e84,
`display: inline-flex` was added to `.pill-container` but
`flex-wrap: wrap` was missing which forced overflow pills to be on
one line and made the pill text overflow vertically. This was not
observed in composebox pills as `.pm_recipient .pill-container`
already had a `flex-wrap: wrap` rule which has been removed in this
commit to avoid duplication.
We were passing this in before, but having it as
a data member reinforces the idea that we'll want
this to be a first-class concept in the list, since
we depend on ordering for various things.
We now keep track of keys in buddy_list.js, so that
when we insert/remove items, we no longer need to
traverse all the DOM. Instead, we just find out
which position in the list we need to insert the
key in (where "key" is "user_id") and then find
the relevant DOM node directly and insert the new
HTML before that node. (And of course we still
account for the "append" case.)
There's a little more bookkeeping to make this
happen, but it should help reduce some code in
upcoming commits and pave the way toward
progressive rendering optimizations.
This commit should produce a minor speedup
for activity-related events that go through
buddy_list.insert_or_move(), since we are
not traversing the DOM to find insertion points
any more.
This will be useful for lazy rendering, where our
buddy_list widget already knows the keys (aka "userids")
it wants to render as you start scrolling them into
view.
Typing "tim " did not did not produce any match when suggesting person
in composebox typeahead or user group typeahead as the space at the
end of the "tim " string passed by the browser was a
`no break-space (U+00A0)` instead of `space (U+0020)`.
Although there are unicode characters other than `no break-space` which
represent spaces, only U+00A0 is replaced as it was the only space
character encountered when testing this issue manually.
Fixes#10039.
This is a fixup for e1291cf839.
While copying the the rules of `#searchbox` to `#searchbox_legacy`
in the search pills feature, the existing `#searchbox` rules were
missed in the conversion.
`#searchbox_legacy` has been added beside `#searchbox` in `media.scss`
instead of replacing that as both of them need those rules for the
mobile view.
Currently, if you access an article link with an anchor link that isn't
featured in the sidebar, the main article won't be highlighted. Thus, we
exclude the anchor link hash from the article-searching selector if
the full article pathname wasn't found.
Shrinking the widths enables all five core team profiles to be aligned
on the same line, instead of having four on the first line and one
profile on its own line.
Fix#10008.
To reduce code duplication when creating hotkey deprecation notices,
create the `get_hotkey_deprecation_notice` function. Also, create a
`ui` testing file with a test for the new function.
Fix#10004.
This replaces some old code with calls to topic_data.js.
Now our topic typeahead uses the same data as our
sidebar, stream suggestions, and the "n" key, so any
future improvements to that data will benefit all
features the same.
This is an important piece of #9857.
Now that `emoji_collection` and `emojis_by_name` are global
datasources in the webapp we need to rename things carefully
to reflect their actual meaning. The fact that emoji code is
used as a css class for unicode emoji is one thing but it is
not its sole use so renaming it seems a good idea.
This commit moves the `emoji_collection` datasource in the emoji
picker to emoji.js and renames it to `emojis_by_name`. It is a
mapping from emoji name to object where each object describes an
emoji. This is an effort in the direction of de-duplicating and
unifying the datasets being used by various our widgets(like
emoji picker and composebox typeahead) in the webapp. Migrating
all the widgets to a single datasource will help us in removing
the whole class of annoying bugs which causes some emojis to be
missing from some widgets.
