This function no longer sets properties to false, so the supported
way of doing this is to instead use prop(foo, false). Some tests
had to be fixed to accommodate this.
We eliminate `.get(0)` calls in buld_stream_list.
The easy case is that we stop building jQuery objects
for the splitters only to pull out the DOM immediately.
The more subtle case is that we also don't do `.get(0)` calls
to get DOM out of our individual list items. By passing
in full jQuery objects to `append()`, we should prevent ourself
from orphaning the old objects, which may in the future have
things like tooltip logic attached to them.
Now we use a consistent approach to find the list items for
Home/Starred messages/Mentioned in the upper corner.
In particular, we get rid of the complicated
iterate_to_find() function.
Given a stream id, we now find list items using the internal
data structures we created when we built the sidebar, rather than
using a jQuery selector.
This change should lead to clearer tracebacks when our
assumption about the stream list's list items get
violated, and we also short circuit some code in the
caller that tries to scroll to the active stream.
In stream_list.js we have some code to handle narrow activations,
and we were calling unread_ops.process_visible() only for
stream activations, not for PM-related activations, etc., so
our approach was inconsistent.
It also turns out that the call is redundant, since we call
unread_ops.process_visible() when the message pane scrolls as
part of updating the content.
Ideally, we want a more rigorous approach where we make this
call precisely when the new messages become visible to the user,
but the purpose of this fix is to de-clutter the stream_list
logic.
If you were narrowed to an unpinned stream, and then pinned it,
we were mostly redrawing the sidebar correctly, but we weren't
setting the active-filter class. Now we accomplish this by
calling maybe_activate_stream_item(), which also reduces some
code duplication. (The new code introduces a bit of extra logic
to do `stream_li.addClass('active-filter')`.
This commit changes stream_data.in_home_view() to
take a stream_id parameter, which will make it more
robust to stream name changes.
This fixes a bug. Now when an admin renames a stream
you are looking at, it will correctly show itself to
be un-muted. (Even with this fix, though, the stream
appears to be inactive.)
Some callers still do lookups by name, and they will
call name_in_home_view() for now, which we can
hopefully deprecate over time.
Rather than having get_stream_li() look up stream id using
stream name, we force the callers to pass in the stream id.
This adds an extra line to most of the callers for now, but
this will eventually change as we fix some of the callers to
have their callers pass in stream_id.
In places where we now call stream_data.get_stream_id() to
get the stream id, we will be more resilient toward stream
renamings, at least until the next reload, since
stream_data.get_stream_id() can resolve old names that
are stored when we process stream-rename events.
We no longer have get_stream_li() delegate to get_filter_li(),
which simplifies the logic in get_filter_li() and makes
get_stream_li() more direct.
We also move the two functions closer to each other in the file.
The function modals.is_active() can see if modals are open
without having to look at the DOM. This should make it snappier
to type in the compose box. Even if the speedup is pretty minor,
not having to worry about jQuery slowness should make it easier
to diagnose future compose box issues.
The new function gets used in other places, too, where performance
isn't so much an issue.
If we pin a stream, we now scroll up as needed to make sure the
stream is still in view after pinning it. (Note that we don't do
this in the un-pinning case, since users un-pinning stuff may be
doing cleanup on pinned streams they no longer care about.)
Fixes#1714.
When we activate a stream (or one of its topics), we now scroll
the sidebar so that the stream comes into view. We scroll it
just enough to get it to the top or the bottom, depending on
where it had been offscreen before.
Despite the length of this commit, it is a very straightforward
moving of code from narrow.js -> narrow_state.js, and then
everything else is just s/narrow.foo()/narrow_state.foo()/
(with a few tiny cleanups to remove some code duplication
in certain callers).
The only new functions are simple setter/getters that
encapsulate the current_filter variable:
narrow_state.reset_current_filter()
narrow_state.set_current_filter()
narrow_state.get_current_filter()
We removed narrow.predicate() as part of this, since it was dead
code.
Also, we removed the shim for narrow_state.set_compose_defaults(),
and since that was the last shim, we removed shim.js from the app.
Before this change, we would move "dormant" streams to the bottom
of your stream sidebar, but only if you had 40+ streams.
Now we do this in all cases to be more consistent.
This commit also changes the redraw strategy when we remove rows.
Before this change, we were doing incremental updates, but now we
call build_stream_list to do a complete rebuild. This was partly
motivated by adding the new divider, which would have complicated
the incrememental approach when you removed the last remaining
dormant stream.
The <hr> is supposed to separate the pinned streams from the unpinned
streams, so if the <hr> is the first element (checked by doing
$hr.prev().length === 0), then it means there are no longer any pinned
streams and therefore it isn’t necessary to have a divider.
Fixes: #4395.
The pinned streams were sorted in alphabetic order (i.e. Verona appears
before devel). The reason is that after we plucked pinned streams out from
stream_data.subscribed_streams(), we didn't sort them again, so they
remained in the alphabetic order used in stream_data.
However, we did sort unpinned streams explicitly by using custom compare
function in stream_list.js (by default sort by lowercase stream name,
but when there are more than 40 subscribed streams, sort active streams
first). That's why this issue only relates to pinned streams.
Changes were made to sort pinned streams by lowercase stream name, always,
whether they are active or not (different from unpinned streams).
Tests were added to ensure this overall sort order is correct, i.e.
1. pinned streams are always sorted by lowercase stream name.
2. pinned streams are always before unpinned streams.
3. unpinned streams are sorted by lowercase stream name, if there are more
than 40 subscribed streams, sort active streams at the top, among active
and inactive streams, still sorted by lowercase stream name.
Fixes#3701
In a96fdd18b1, I introduced a few
regressions related to the blue highlighting that happens
in the top left corner for Home, Private messages, Starred
messages, and @-mentions. Basically, we weren't clearing
the highlighting when we thought we were, so Home would stay
blue too long and the other filters wouldn't turn blue.
We went a surprising long time before noticing the regression.
This fix adds a function called deselect_top_left_corner_items()
to clear the blue backgrounds, so that will happen more explicitly.
And then I restored a line of code to pm_list.js that puts the
blue in place when you are in an is:private narrow (vs. a
specific PM narrow).
The fix works by having build_stream_sidebar_row()
automatically update its own unread count when we
build a sidebar row. Currently we rebuild sidebar
rows when we pin/unpin rows.
As an aside, we currently don't really need to rebuild
the sidebar row when we pin, since we're only moving
the DOM, not altering it. But this may change in the
future, so I decided to leave that code path in place.
We may decide to do things in the future like showing
pinned streams with bolder fonts or special icons or
whatever.
Fixes#2902
Some of the work here was done Tomasz Kolek.
When we click on "more conversations" in "Private Messages,"
we call it being "zoomed in." Before this change, when
new PMs arrived, we would rebuild the list and zoom out
again. Now we track the zoomed_in state with a variable.
Also, if you are zoomed in and switch from one PM narrow
to another, we also keep you zoomed in.
This fix also removes some extraneous/redundant code.
