We recently added a feature to warn users that they
may need to scroll down to view messages that they
just sent, but it was broken due to various complexities
in the rendering code path.
Now we compute it a bit more rigorously.
It requires us to pass some info about rendering up
and down the stack, which is why it's kind of a long
commit, but the bulk of the logic is in these JS files:
* message_list_view.js
* notifications.js
I choose to pass structs around instead of booleans,
because I anticipate we may eventually add more metadata
about rendering to it, plus bools are just kinda brittle.
(The exceptions are that `_maybe_autoscroll`, which
is at the bottom of the stack, just passes back a simple
boolean, and `notify_local_mixes`, also at the bottom
of the stack, just accepts a simple boolean.)
This errs on the side of warning the user, even if the
new message is partially visible.
Fixes#11138
We now have two functions:
add_new_messages
add_old_messages
This is a lot easier on the eyes, and it will also
prevent us from exceeding line length in future commits.
We also remove an unneeded stub in the narrow_activate
tests.
This commit makes it a bit more explicit about
why we're updating 2 or 3 message lists every time.
It looks funny now to repeat the home-list updates
in both sides of the conditional, but this will be
more obvious in a subsequent commit, where we want
to capture return values from rendering.
In a recent commit we allowed for `scroll_amount`
to be zero (as an indirect consequence of letting
`scroll_limit` be zero without early exiting).
See 0f75be3e8e
We want to short circuit the call to
`system_initiated_animate_scroll`, partly to save
unnecessary computation, but in particular to avoid
invoking the suppress-pointer-update logic.
It's convenient to have visible_bottom as well
as top/height, and the extra computation is
trivial (it's just arithmetic, no extra jQuery
involved).
There's some minor cleanup here too.
Guest users can not add subscribers to subscribed or unsubscribed
streams. Therefore hide add-subs html element if current user
is guest user.
Tweaked by tabbott to use the early-return pattern.
Add explanation in popover on disabled add-subscriptions input elements,
admin can't add subscribers to non subscribed private streams, only
subscribed users can.
Fixes#10593
There's a subtle change here in how we handle the
hypothetical case that the selected message is above
the top of the feed. Instead of early-exiting
from _maybe_autoscroll(), we just treat the limit
as zero, which will have the same effect.
We also change a var name be just `scroll_limit`
instead of `available_space_for_scroll`. A longer
name would be valuable if it were somehow more
specific, but it was needlessly verbose.
The idea is to use this field for storing the best matching alias
to be displayed in search results. In subsequent commits I will
replace the search and rendering logic to use this field instead
of creating new objects on each search.
Since we have already added the `invite_as` field to models, we can now
replace usage of `invite_as_admin` properly with its equivalent `invite_as
== PreregistrationUser.INVITE_AS['REALM_ADMIN']`.
Hence, also removed now redundant `invite_as`.
This couples the behavior of Enter to Save with Enter to Send.
Extracts and exports functions responsible for checking if enter
does send/edit and handling default behavior otherwise.
Changes made in static/js/message_edit.js and
static/js/composebox_typeahead.js
Fixes#10320.
This adds two functions to static/js/composebox_typeahead.js.
should_enter_send(event) checks if enter should actually send.
handle_enter(textarea,event) emulates browser's default behavior
if enter doesn't send.
These two are just straight extractions of portions of the compose box
logic.
It's a bit dangerous for the user to hit escape
to close the feedback widget, since it can
disappear suddenly, but users will try it, and
we should just close the widget.
(Hitting escape should be a noop if the box
is closed, but now it goes to "All Messages".)
We only need these once, not during every show()
call. We actually were only setting up the
click handlers one time, but we had redundant
mouse handlers.
More importantly, we stop a runaway timer
that tries to fade out our feedback widget
every 100ms or ten times per second!
A few things are still hard coded, but the class exposes
show() and dismiss() now.
The show() method is configured with callbacks for
populate() and on_undo().
We calculate a few values higher up in the function.
This reduces a bit of code duplication and removes
a somewhat janky expression that happens against
a mutated list.
I use shorter var names in frb_botom() and do early
return in obscured_recipient_bar().
Also, we always call exports.hide() if we don't find
a valid recipient bar to "float."
There is no reason not to initialize people.js
super early in the process, as it only reads
data from page_params. Also, other modules
are likely to want its data during their own
initialization steps.
This is the preferred way to check that a user
id belongs to the current user.
We have a recent bug where the current user's
circle doesn't turn green right away. It's not
clear this is the fix, though. (It's hard to
repro locally.)
This is mostly for testing purposes. The code
structure here is pretty stable--we will probably
always use level() here to either sort or
group users, and being able to test it directly
is nice, rather than bringing in all the other
machinery.
This makes it possible it include our standard markdown formatting in
one's custom profile fields, allowing for links, emphasis, emoji, etc.
Fixes#10131.
While we're at it, we remove the JSON parsing that was part of the
user field code path, since this function isn't responsible for
rendering user fields.
Apparently, our custom profile fields feature was parsing the "user
list" field type in multiple places, and ignoring the results in one
of them. That code had been causing some confusion; the correct
solution is to just delete it, since the template rendering process
ignores that value for this field type.
Our logic for doing pageup/pagedown calculation inside compose was
written too tightly, and ended up breaking the keys inside message
editing.
Fix this by using generic selectors that don't hardcode compose.
Previously, messages with more than one line did not parse '/me' at
the beginning of the message. Since there's a reasonable way to
render multi-line messages, this commit adds support for doing so.
This change does potentially break with the expected behavior of other
slash commands, but it seems worth providing useful functionality over
a blind focus on consistency.
Fixes#11025.
If branch for showing the profile details would
not have executed if the subdomain was root ("").
The check was changed to check for select input
instead of checking for subdomain.
This avoids a bunch of potential confusion around users trying to
interact with these UI in situations that don't make sense.
(E.g. showing a menu to start editing the message when the menu is
already open).
Fixes#3802.
We instead get the specific fields from message
that we use. This is particularly helpful
for subject -> topic migration; we no longer
have to account for "subject" fields in
client-side templates.
This continues the effort to isolate "subject" references
to util calls.
Also, we fix a comment.
Finally, we use canonicalized operators in a switch
statement.
As part of giving the stream/topic fields in the
compose box longer ids, I broke the autocomplete
code that handles re-focusing the cursor after
a user hits enter. The worst symptom of this was
that we tried to send a message before compose
finished (although it wouldn't fully deliver the
message).
The new code should be a bit easier to grep for
if we rename these fields again, as we explicitly
use selector syntax.
Previously, we were searching the whole message_row object for emoji,
mentions, etc., which has a bunch of UI elements that can't contain
the syntax we want to modify. This should be a slight improvement in
the performance of message post-processing, which runs a lot of times
and thus is fairly important.
