If an else block only contains an if statement, the two can be
combined into an if-else block, which cuts down on indentation
and usually helps legibility.
There are exceptions (for instance where the outer if and else
blocks are mirrored), but where it makes sense, change the code
to avoid lonely ifs.

Resizing effects are more finicky as other effects, as the actual
animation is delayed until we receive the ::size-changed signal.
However that signal may never be emitted if the window is destroyed
just after starting the size-change effect, in which case the effect
is never completed, blocking mutter from destroying the corresponding
window actor.
Address this by tracking when a resize effect is pending, and complete
the effect when appropriate.

Clutter originally cluttered its namespace with key symbols, before
prefixing all symbols with KEY. We still use the unprefixed symbols
occasionally, replace them so mutter can drop the deprecated symbols.

Every since commit aa394754, StBoxLayout has supported ClutterActor's
expand/align properties in addition to the container-specific child
properties. Given that that's the only container left with a special
child meta, it's time to fully embrace the generic properties (and
eventually remove the child meta).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/780
Remove all transformations from window actors after a window animation
was either cancelled or finished. Right now we only do that if the
transition finished successfully, which seems kind of pointless (it can
probably be historically explained because the callbacks inside the
"kill-window-effects" signal handler are connected to those
`*WindowDone()` functions though and the `*WindowOverwritten()`
functions were only added later in [1]).
This fixes a recent regression where a window animation would get
cancelled and remain stuck by switching workspaces. The regression
probably happened due to different behaviour of the `onOverwritten`
callback of Tweener and the `onStopped` callback of Clutter transitions:
For the workspace-switching animation the window actors get reparented
to a temporary container, which makes Clutter transititons emit
"stopped" (`clutter_actor_remove_child_internal()` stops transitions on
its children), while Tweener would continue the animation.

Remove the `this.actor = ...` and `this.actor._delegate = this` patterns in most
of classes, by inheriting all the actor container classes.
Uses interfaces when needed for making sure that multiple classes will implement
some required methods or to avoid redefining the same code multiple times.

As arrow functions have an implicit return value, an assignment of
this.foo = bar could have been intended as a this.foo === bar
comparison. To catch those errors, we will disallow these kinds
of assignments unless they are marked explicitly by an extra pair
of parentheses.

We now do 2 things along Xwayland startup/shutdown:
- Start or stop the gnome-session-x11-services target, that will
pull all X11 related services that the session might depend on.
- As we start ibus-daemon manually, trigger a restart in order to
toggle the XIM daemon on and off along with Xwayland presence.

Properties that aren't marked as animatable don't support *implicit*
animations, but they can still be animated with explicit transitions.
Use the newly added convenience method to cut down further on Tweener
usage.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
The set_brightness() method is the most convenient way of controlling
the effect's brightness, but Clutter animations only deal with properties,
so start using the (ClutterColor) brightness property instead.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
Currently WindowDimmer exposes a JS property that is used to control the
underlying effect. This works fine with Tweener, but not with Clutter
animations which we want to use ultimately.
As a first step towards that, expose a setDimmed() method instead of
the property and handle the animation internally, so it can be adapted
more easily.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/666
We now have everything in place to replace Tweener for all animatable
properties with implicit animations, which has the following benefits:
- they run entirely in C, while Tweener requires context switches
to JS each frame
- they are more reliable, as Tweener only detects when an animation
is overwritten with another Tween, while Clutter considers any
property change
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/22
The different units - seconds for Tweener and milliseconds for
timeouts - are not a big issue currently, as there is little
overlap. However this will change when we start using Clutter's
own animation framework (which uses milliseconds as well), in
particular where constants are shared between modules.
In order to prepare for the transition, define all animation times
as milliseconds and adjust them when passing them to Tweener.

Those unused arguments aren't bugs - unbeknownst to eslint, they all
correspond to valid signal parameters - but they don't contribute
anything to clarity, so just remove them anyway.

While mutter supports a variety of different grid layouts (n columns/rows,
growing vertically or horizontally from any of the four corners), we
hardcode a fixed vertical layout of a single column.
Now that mutter exposes the actual layout to us, add support for a more
traditional horizontal layout as well.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/575
Braces are optional for single-line arrow functions, but there's a
subtle difference:
Without braces, the expression is implicitly used as return value; with
braces, the function returns nothing unless there's an explicit return.
We currently reflect that in our style by only omitting braces when the
function is expected to have a return value, but that's not very obvious,
not an important differentiation to make, and not easy to express in an
automatic rule.
So just omit braces consistently as mandated by gjs' coding style.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/608
While we have some style inconsistencies - mostly regarding split lines,
i.e. aligning to the first arguments vs. a four-space indent - there are
a couple of places where the spacing is simply wrong. Fix those.
Spotted by eslint.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/608
We are currently inconsistent on whether case labels share the same
indentation level as the corresponding switch statement or not. gjs
goes with the default of no additional indentation, so go along with
that.

We can use that newer method where we don't care about the actual position
of an element inside the array.
(Array.includes() and Array.indexOf() do behave differently in edge cases,
for example in the handling of NaN, but those don't matter to us)

Using one variable to initialize all gestures will update the address of
the "gesture" pointer with every newly initialized object. This means
that event handlers which also use the "gesture" pointer like the
'keyboard-visible-changed' handler will update a different gesture as
soon as the pointer is changed.
This lead to a bug where the handler of 'keyboard-visible-changed'
wrongly nabled the unfullscreen gesture. Fix that by assigning each
gesture its own variable.

The `switch-to-application-n` shortcuts are essentially "launch the nth
app in the dash" actions, so they are at the very least confusing when
the dash isn't available because the overview itself is disabled (for
example in initial-setup mode).
So disable the shortcuts when the overview is disabled, but delegate the
decision to a separate function so that extensions like 'panel-favorites'
which expose favorites by some other means can easily re-enable them.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1333
Make the dialog a widget itself, removing the `_group` property used for
handling the actor.
Update all the inherited classes to be also GObject implementations, moving all
the signals to proper object ones.

To prevent a small gap between windows in the workspace switching
animation, we temporarily shift windows up or down by the height of the
panel. This obviously breaks the animation for fullscreen windows, those
will overlap with the ones on the other workspace since there is no
panel shown in that case.
Fix this by checking whether the old or new workspace includes a
fullscreen window and don't shift the windows if there is one.
Fixes https://gitlab.gnome.org/GNOME/gnome-shell/issues/757https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/322
If a window gets destroyed right before it's resize
animation starts the user can get confronted with an undead
zombie clone that doesn't go away.
This commit makes sure said clones get reaped with their
actors.

Inserting a workspace is implemented by appending a new workspace, then
shifting all windows after the "new" workspace up. This has an unintended
side effect on sticky windows, as changing its workspace will unstick it.
Fix this by excluding sticky windows - there's little point in moving them
anyway, given that they should be on all workspaces (including the original
workspace and the target one).
https://gitlab.gnome.org/GNOME/gnome-shell/issues/1151
The window group is hidden while in overview, so the stick-to-content
animation isn't visible either. Worse, the gestures messes up the
position of window actors in that case. Just limit the gesture to
normal mode for now, we will soon add it back in the overview with
its own animation handling.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/516
The touch/touchpad gestures to switch workspace currently hard-code
the modes in which we want the gestures to work. While these modes
are correct, the existing switch animation only works in NORMAL mode,
not in the overview where the window group is hidden. The easiest way
to address this is to handle both cases completely separately, namely
use separate actions in- and outside the overview.
Make the existing usable in that way by making the list of allowed
modes a constructor parameter.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/516
The top drag gesture is not of any use if the topmost window is not
a fullscreen window and will only block events near the important top
screen edge (i.e. the panel). To fix this, only enable this gesture if
the focus window is a fullscreen window.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/552
Having Unity-like shortcuts for activating the first nine applications
in the dash has been a long requested feature, but somehow nobody got
around to implement it.
As the shortcut is most useful outside the overview where the dash is
not visible, only consider favorite apps as they have a predictable
order.

ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

When using dynamic workspaces, it is possible to try to change to a
non-existent one if the user defines hotkeys for changing to desktop
1, 2, 3... This case is not detected, and gnome shell shows an error:
JS ERROR: TypeError: workspace is null
actionMoveWorkspace@resource:///org/gnome/shell/ui/windowManager.js:2130:13

This patch adds a check before trying to change the workspace, to avoid
switching to a non-existent one.

Instead of defaulting to a natural scroll behavior,
have the workspace switch action use the natural-scroll setting
in org.gnome.peripherals.touchpad to determine the correct
direction of travel when swiping. 4 finger swipes will then
match the behavior of the rest of the UI.

Shell.GenericContainer exposes the size negotiation machinery
through the use of signals. Signals are not specially performant.
One of the reasons is that they acquire a global lock for signal
handlers lookup. GNOME Shell has more than 2,000 actors at any
given point in time, up to 20 levels deep in hierarchy, making
size negotiation and painting non-trivial tasks. Such a critical
section of Clutter's machinery shouldn't rely on signals
whatsoever.
Regardless of that, Shell.GenericContainer is a workaround to
a non-existing issue anymore. It shouldn't be used anyway, and
any performance improvements that removing it can potentially
yield are bonuses to it.
This commit starts this work by removing Shell.GenericContainer
usage from Panel.Panel class. The class now extends St.Widget,
and as such, it has no "this.actor" field set anymore. A couple
of places where this actor field was used are adjuste as well.
It is important to notice that we now allocate the Panel itself
inside vfunc_allocate(). This was previously done before emitting
the signal by Shell.GenericContainer.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/153
Since we always keep the active workspace until the user switches
to a different one, we may end up with two empty workspaces at
the end. It's not obvious to users why this happens, and there's
indeed no good reason for the behavior - just remove the trailing
workspace in that case.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/536
GSettings now recognizes per-desktop overrides that can be used
to change schemas' default values for a particular desktop. This
is not entirely unlike our existing custom override mechanism in
mutter, except that it is not limited to keys in org.gnome.mutter,
and it doesn't require a separate schema - the latter means that
we (and gnome-teak-tool) no longer have to figure out the correct
schema for the current login session and just use the original one.

Commit e5c95b910d refactored the workspace animation to also handle
animations that involve all surrounding workspaces, but due to an
ill-advised review comment (guess whose) it broke the animation
for non-neighboring workspaces.
Update the code to handle correctly whether in a given direction:
- we have the target workspace of a given index
- we have a neighboring workspace
- we don't need to animate anything
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/182
When 4fg swipe motion happens, set up early the workspace switching
animation with all surrounding workspaces. This allows us to move
all content back and forth in any direction. This works on both
touchcreens and touchpads.
When the gesture is activated, the same data is reused to follow
up with the tween animation.
The threshold has been also doubled, it was fairly small to start
with, and feels better now that workspaces stick to fingers.
https://bugzilla.gnome.org/show_bug.cgi?id=788994
Besides the separation into distinct functions, the stored data has
been made able to generically store windows from all surrounding
workspaces. All while keeping a special mode to animate between two
workspaces (The usual till now), this is the only mode exercised so
far.
In order to ease animations, all window groups are now children of
a common container, which is then animated.
Fullscreen windows cannot be restored by touch device users unless the
application adds support for it.
As it is unlikely to change all application lets introduce a top edge
drag gesture which unmakes fullscreen windows.

Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved

When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.

On the screen shield, the only possible interaction is lifting the
shield. The on-screen-keyboard is not useful for that, and the drag
gesture from the bottom may in fact conflict with dragging up the
shield, so disable it.

Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.
https://bugzilla.gnome.org/show_bug.cgi?id=785084
The destroy effect currently relies on a monkey-patched property
added from the map effect. However on X11 it is possible that we
did no map animation for a window that is destroyed when the shell
was restarted or had taken over from another WM. Just use the real
MetaWindow property to avoid a warning in that case.
https://bugzilla.gnome.org/show_bug.cgi?id=781471
The fullscreen animation code is now generic enough to handle any
size change animations, so stop limiting it to (un)fullscreen to
get animations on (un)maximize as well.
https://bugzilla.gnome.org/show_bug.cgi?id=766685
Currently, the translation values are set with the assumption that
one of the actors represents a fullscreen window. In order to
generalize it for any size change transition, we can simply swap
the monitor rect with the source or target rect as appropriate,
and translate the actor from the target to the source position by
subtracting the former and adding the latter.
https://bugzilla.gnome.org/show_bug.cgi?id=766685
Since there is already targetRect that represents where the
window is going to move, rename oldRect to sourceRect to
represent from where the window is moving.

GJS implements a basic signal system that allows monkey-patching
