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.

Although SimpleBar automatically sets itself up on elements with a
`data-simplebar` attribute, sometimes we try to set event listeners
before that happens. Create the SimpleBar early in that case.

With perfectScrollbar, we needed to call a function from JavaScript to
enable a scrollbar on a new element, but simplebar has a much simpler
default API one can do by using data-simplebar attributes in the HTML.
So we can delete all the scrollbar creation/deletion code.

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.

In between releases, the following commit introduced
a bug where we agressively scroll to the top every
place we call `ui.update_scrollbar`:
092b73d0b7
The main symptoms were that the left and right sidebars
would go to the top for things like selecting a topic,
getting activity updates from the server, and resizing
the window. It was very jarring.
The recent commit looked innocuous--the root of the problem
was the original API expressed an intent to scroll to the
top, but didn't actually do it, so it was a bug in hiding.
There are **some** occasions where it's actually appropriate
to scroll to the top, mostly around search filtering, and
in those places we now call the new `ui.reset_scrollbar`
function.
This is a bit of an emergency fix, so particularly with
the settings stuff, we may get more reports of glitches here.
The important thing here is that you almost never want to
reset the scrollTop for sidebars.
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 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.
There are several ways we open help for keyboard shortcuts,
markdown help, and search operators.
- from the gear menu
- from the compose box
- from the search box
- hitting ? for keyboard help
- arrowing/clicking through the tabs
This just moves the relevant code into a module and changes a
bunch of one-line calls in various places.
Update perfect-scrollbar to fix stutter space-scrolling in #8544. Also
reworked deprecated `element.perfectScrollbar` to `new
PerfectScrollbar(element)`. Lastly, updated provision version and
changed node module path to new path.
This also refactors perfect-scrollbar in help.js to work with updated
version of perfect-scrollbar. Because the update also changed
perfect-scrollbar's css selectors for all scrollbars in zulip, we
update those too.
Fixes#8544.
This mostly moves code from ui.js.
We change the arguments to `message_fetch.load_more_messages()`
to be `opts` with callbacks for `show_loading` and `hide_loading`.
We also defer starting the scroll handler until `message_fetch.js`
has been initialized.
There is a bug on MacOS on Zulip where the categories are all
duplicated due to faulty looping logic, while also changing the Map to
an Array since maps have less cross-browser support.
We now do all of the main logic for starring/unstarring
a message in `message_flags.toggle_starred`:
* mark the message as read (just in case)
* update the UI (i.e. the green star in the message)
* update the server
The calling code in both the click handler and the hotkey
handler remains simple--they just handle minor details like
finding the message and clearing popovers.
For updating the server, we now call the new
`send_flag_update` helper.
And we continue to delegate some of the logic to
`ui.update_starred`, but we remove some code there that's
now pushed up to `message_flags.toggle_starred`.
This change should be mostly transparent to users, but it
does remove some inconsistent behaviors between the click
handler and the hotkey handler. Before this change, the
click handler was more aggressive about updating the UI
and marking the message as read. For people using the "*"
key to star/unstar, they probably would only have noticed
different behavior on a slow connection or in an edge
case scenario where only half of the message was onscreen.
More importantly, by simplifying how we talk to the server,
this eliminated up to a one-second lag due to the debounce
logic in the batch_updater code. The complicated debounce
logic is only really needed for batch-updating "read"
messages, and it was overkill and sluggish for starring
messages.
Last but not least, we add defensive code for the local
echo case. (Users have to wait till the message gets acked
to star it.)
This adds custom CSS through JavaScript for things that do not
scope well and will override other inherited styles.
This should ONLY be used for problematic CSS that has no obvious
or easy CSS-only solution.
(Specifically, we need this for the "default link" styling, which is
hard to override because we don't want to start winning ties due to
specificity that we would not have won in the light theme).
The `have_scrolled_away_from_top` logic goes way back
to November 2012.
Now we unconditionally load older messages when we scroll
to the top of the feed. Before this bug, you could get
"stuck." It was a bit difficult to reproduce, but with
the right combination of render window sizes and batch
sizes, you would hit the home key quickly and hit the top
of the feed in a way that the flag got in the way of
going back in history.
Fixes#6628
This commit switches to use sprite sheets for rendering emojis
in all the remaining places, i.e., message bodies and composebox
typeahead. This commit also includes some changes to notifications.py
file so that the spans used for rendering emojis can be converted
to corresponding image tags so that we don't break the emoji rendering
in missed message emails since we can't use sprite sheets there.
As part of switching the bugdown system to use sprite sheets, we need
to switch the name_to_codepoint mappings to match the new sprite
sheets. This has the side effect of fixing a bunch of emoji like
numbers and flag emoji in the emoji pickers.
Fixes: #3895.
Fixes: #3972.
Our old optimizations to prevent re-rendering of locally echoed
messages created a lot of code complexity. This commit is an
experiment to simplify the code, which it clearly does. The
danger of re-rendering messages is flicker, but our message
view has changed since the original local echo code was written.
Checking for window.bridge !== undefined is how the old desktop app
had always been tested for in the JS codebase.
Also, "Zulip Desktop" is how this should have been spelled in the first place.
Tweaked by tabbott to provide a proper commit message.
Fixes#6580.
This displays an error at the top of the screen on page load that
will inform any user with the userAgent string "ZulipDesktop" that
they should upgrade to our newer electron app
Fixes: #6551.
These are some strings I spotted in English when playing around a bit
with the UI set to German, where our translations are near complete.
It'd be great to have a more systematic way of spotting this kind of
omission. Probably a fairly simple linter could catch a lot of cases.
This makes it possible for Zulip administrators to delete messages.
This is primarily intended for use in deleting early test messages,
but it can solve other problems as well.
Later we'll want to play with the permissions model for this, but for
now, the goal is just to integrate the feature.
Note that it saves the deleted messages for some time using the same
approach as Zulip's message retention policy feature.
Fixes#135.
