Right now, the actor hierarchy is such that the scroll view
does not contain the actual grid. It looks as follows:
StScrollView
↓
StBoxLayout
↓
ShellStack
↓ ↓
PaginatedIconGrid StWidget
This hierarchy can be slightly reorganized by changing it to be as
follows:
ShellStack
↓ ↓
StScrollView StWidget
↓
StBoxLayout
↓
PaginatedIconGrid
This will simplify future work where the PaginatedIconGrid will be
an implementation of StScrollable, in which case we'll be able to
simply remove the StBoxLayout from there.

If a search provider is installed by an app which is blacklisted for the
current user by their parental controls, don’t show it or results for
it.
Currently, this only filters ‘remote’ (not built-in to the shell) search
providers. This seems fine for now; in future it could be expanded to
also filter built-in search providers, if any of them end up needing to
be filtered.
No corresponding changes need to be made `remoteSearch.js`, because the
results of `loadRemoteSearchProviders()` are filtered in `search.js`.

Filter the apps shown on the desktop and in search results according to
whether they are blacklisted by the user’s parental controls.
This supports dynamically updating the filter during the user’s session.
This adds an optional dependency on libmalcontent. If that’s unavailable, no
parental controls filtering will occur.

While we now deal more gracefully with adapter removals, we can
still mess up the hadSetupDevices tracking:
As adapters become available before any devices, we'll always
reset the setting to false when Bluetooth is turned on. And if
no set up device happens to be in range, it will still be false
when Bluetooth is turned off again.
To address that, only update the setting if we have an adapter
(like we do now) and we had one before (so it wasn't the adapter
itself that changed).
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1174
Our intended behavior when bluetooth is turned off is to keep
the menu visible if devices had been set up previously.
However since gnome-bluetooth@c437c729, devices are removed
first before removing the default adapter, so we now end up
always setting the property to false before checking for it.
Fix this by deferring all model changes to an idle, so that
we can process them as a unit. Do the same for proxy property
changes, as those may trigger a row-removal.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1174
Since commit 26c2cb9f65, nDevices is always the actual number of
paired/trusted devices. So when bluetooth is turned off, it is
now 0 rather than forced to 1 if devices were set up previously.
Fix this by checking the property that tracks set up devices instead.

Pretty much the same case of the previous commit: we want this size
to be scale-dependant, and using the width and height properties of
ClutterActor doesn't automatically update.
Use CSS to set the width and height.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1176
The return value of st_theme_node_lookup_length() is scaled according
to the scale factor. IconGrid.ICON_SIZE is not. However, when BaseIcon
tries to fetch the CSS value for "icon-size" (which returns a scaled
value), it uses it as-is, mixing the two coordinate systems.
Use a single coordinate system (unscaled sizes) in IconGrid.BaseIcon.

Usually the screen is woken up before the shield is deactivated, but
it is also possible to unlock the session programmatically via the
org.gnome.ScreenSaver D-Bus API.
The intention is very likely not to unlock a turned off screen in

state without any indication.
Waking up the screen is more likely to meet expectations and is
more reasonable too, so do that.

Extension that want to expose their own preferences (for example as menu
items) do that by passing their UUID to gnome-shell-extension-prefs.
But since 3.36.1 the app is optional and no longer accepts arguments on
the command line. To adjust, extensions now need to make a D-Bus call
the extensions portal, just like the app and gnome-shell.
We will add a convenience method for that purpose, so it makes
sense to share the existing code. As it's extension-related, the
extension manager looks like the right place ...

A promisified method expects the callback parameter to be either
a function (in which case the original method is called normally)
or omitted altogether (in which case a Promise is returned).
The call to open application details in Software does neither and
passes null instead, which will result in a warning (because no
function argument means a promise will be used, but not omitting
the parameter means we end up with too many arguments).

During the shell initialization we call the (deprecated) function to
override the Desktop environment in Gio DesktopAppInfo to make sure that
applications are correctly shown (as per commit b2fbf5a2), however this
might break the cases in which $XDG_CURRENT_DESKTOP is already set and
contains GNOME (given that is now a list).
In Ubuntu this is in fact set to: ubuntu:GNOME.
Now, if an application contains NotShowIn=ubuntu, the key will be ignored by
the shell, and the application is still listed everywhere.
So, override the DesktopAppInfo desktop environment only in the case that
the current desktop is not already GNOME.
At the current date I think we could just safely get rid of this override at
all, but there could be still cases where it still might be useful, like when
running as nested in some other environment, so keeping it.

Promises make asynchronous operations easier to manage, in particular
when used through the async/await syntax that allows for asynchronous
code to closely resemble synchronous one.

Promise when called without a callback argument.
Use that to get rid of all those GAsyncReadyCallbacks!

Starting the animation from the actor 'paint' signal has various
unwanted consequences, such as sometimes trigger a
clutter_actor_queue_relayout() during the paint phase. One unwanted
consequence was that an offscreen actor effect was disabled during
painting, meaning the effect would begin being active, but later during
the post-paint processing being disabled. The caused said effect to push
an offscreen framebuffer to the paint context, but then just destroy it
instead of popping it. When this happened, we'd end up trying to operate
on a framebuffer that may had been finalized, or not, depending on the
garbage collector. Sometimes, for some users, this caused a segmentation
fault when trying to pop a matrix from the framebuffer matrix stack.
Deal with this more properly, by using the 'view-loaded' signal to wait
with animation until the view is loaded, as well as using MetaLater to
schedule the start of the animation.
For when a view was signalled to be ready, we're in a state where we can
start animation before the next frame as the layout is ready, but when
not, we have to add back the "hack" where we must wait for one frame for
the target icon positions to be up to date. Do this by adding a
MetaLater IDLE callback that starts the animation *after* the next
frame. This also needs the old 'opacity = 0' work around to not show an
incorrect first frame.

It seems there is a weird race condition between Clutter trying to
destroy the keyboard actor and Clutter trying to hide the keyboardBox
container actor: If the keyboardBox is hidden before destroying the
keyboard actor, Clutter doesn't repaint anything and the keyboard
remains visible until something else draws over it.
To fix this issue until we find the underlying Clutter bug, simply
destroy the keyboard actor before hiding the keyboardBox. The order in
which we call these doesn't matter anyway since hideKeyboard(true) hides
the keyboard immediately without an animation.

We're dealing with attached keyboards now using the touch_mode property
of ClutterSeat: If a device has a keyboard attached, the touch-mode is
FALSE and we won't automatically show the OSK on touches, also the
touch-mode gets set to FALSE when an external keyboard is being plugged
in, so that also hides the OSK automatically.
With that, we can now ignore keyboard devices when updating the last
used device and no longer have to special-case our own virtual devices.
Because there was no special-case for the virtual device we use on
Wayland now, this fixes a bug where the keyboard disappeared after
touching keys like Enter or Backspace.

The Extensions app code is now independent enough from the rest of the code
base to move it to its own subprojects, like we did for the extensions-tool.
This allows for stand-alone builds of the app, which we are about to use
for distributing it as flatpak.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1133
We include config.js because it is a dependency of ExtensionUtils,
but it's not actually used in the code paths we exercise.
As we want to allow stand-alone builds of the app, it is much easier to
fake the module than to either include a generated file from elsewhere
in the tree or generate it ourselves.

Instead of adding a dragMonitor for every icon in the grid as soon as
one icon is getting dragged, only add a dragMonitor for the icon that is
currently being dragged over (ie. the current drag-target). With a large
number of icons in the iconGrid, this should significantly reduce lags
while dragging.
We can do this by detecting the DnD-entering of an icon or folder using
the `handleDragOver()` callback of drag-targets, adding the dragMonitor
because we know an icon is hovering above the drag-target and then
detecting the DnD-leaving of the drag-target by using the `dragMotion()`
handler, where we remove the dragMonitor again as soon as the
targetActor is no longer our actor (ie. the drag-target).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/849
While it should be impossible to destroy a FolderIcon while a DnD action
is still going on, there might still be rare cases where this happens
(ie. when a folder is removed because an app got deleted during DnD).
So make sure we're on the safe side here and don't potentially leave
dragMonitors around after the icon is destroyed by removing the
dragMonitor inside the onDestroy handler of the FolderIcon, just like we
do for AppIcons.

Forward the arguments at the 'delete-surrounding-text' signal
from IBusInputContext to clutter_input_method_delete_surrounding()
so that ibus-typing-booster use the deleting surrounding text function.
Input method engines can delete the output text in applications

This change will require a change of mutter of mutter!517
because the first arguemnt of the 'delete-surrounding-text' is INT
to express the offset of the current cursor position but
the first one of clutter_input_method_delete_surrounding() is UINT
since the Wayland spec accepts UINT in delete_surrounding()
mutter will change the type of the first one to INT in

Blacklist support was added all the way back in commit 1e286e43, but
the code had been defunctional until recently. While uninstalling an
extension that has been blacklisted makes sense off-hand, unfortunately
we don't know if an extension was *actually* blacklisted:
The website returns that operation for any extensions for which it
doesn't find any versions that match the shell version. That is, the
most likely reason is that the user updated to a new GNOME release
which the extension doesn't support yet.
It doesn't look like the website is going to change that behavior any
time soon[0], so drop the 'blacklist' handling for the time being.

Since PackageKit 1.11.1, the prompt to install updates on the end
session dialog has been (mostly) broken. The problem is that it only
works if PackageKit is running at the time the end session dialog is
opened; otherwise, our GDBusProxy has invalidated all of its properties,
which we read to see if update is possible. We need to autostart
PackageKit before reading its properties to fix this problem. That would
be easy if we were calling a method to see if an update or distro
upgrade were available, but since we're just checking a property, using
cached properties won't suffice. We'll have to manually check the
property value to ensure we autostart PackageKit.
Most of the code is written by Florian. Thanks Florian!

As outlined earlier, in order to turn the Extensions app into a properly
sandboxed application, we need to split out the extension prefs dialog
and move it elsewhere.
With "elsewhere" being the new Extensions D-Bus service, effectively
turning it into a shell extensions portal.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1106
Similar to the previously added org.freedesktop.Notifications proxy,
this exposes the org.gnome.Shell.Extensions API and forwards any
request to the real implementation in gnome-shell.
The motivation differs though: We want to be able to package the
extension app as flatpak and distribute it separately, but the
extension prefs dialog is hard to impossible to sandbox:
- filenames need translating between host and sandbox, and we
can only do that in some cases (serializing/deserializing
extensions), but not others (extension settings that refer
to files)
- system extensions install their GSettings schemas in the system
path; the best we can do there is assume a host prefix of /usr
and set GSETTINGS_SCHEMA_DIR in the flatpak (eeks)
- extensions may rely on additional typelibs that are present on
the host (for example because gnome-shell itself depends on
them), but not inside the sandbox - unless we bundle all of
gnome-shell's dependencies
- if gjs/mozjs differ between host and sandbox, extensions must
handle different runtimes for the extension and its prefs
And all those issues occur despite a very permissive sandbox (full
host filesystem access, full dconf access, full org.gnome.Shell
access (including Eval()!)).
This new service will give us an alternative place for handling
the preference dialog:
- it runs outside of gnome-shell process, so can open windows
- it runs on the host, so the extension's prefs get to run
in the same namespace as the extension itself
That is, the service will provide portal-like functionality (albeit
not using the org.freedesktop.portal.* namespace, as extension
management is an inherently privileged operation).
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1106
We are jumping through quite some hoops to support showing only the
preference dialog when given a UUID on the command line.
As gnome-shell is about to stop calling out to us for the prefs dialog,
the reason for supporting this is going away, so remove all the special
handling.
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1106
The dialog that contains the extension's preference widget has become
fairly complex over time, mostly due to the error handling.

On X11, _onFocusChanged() updates the input region, as well as the
reactive-ness of the dialog's buttons.
That method is not only used as signal handlers (which are correctly
disconnected when the dialog is hidden), it also runs when the "show"
transition completes.
That's a problem if the transition is still ongoing when the dialog is
hidden, as it will then only complete when it is replaced by the "hide"
transition, after the this._dialog has been reset to null, and trying
to access the dialog's buttons results in an error.
Avoid this by explicitly removing all transition on hide before
resetting the dialog.

Commit c1ec7b2ff meant to fall back to the base layout in case

Using the "regular" loadInterfaceXML() helper means less code duplication,
but it also ties us to the resource used by gnome-shell.
In order to untangle the extension app from core gnome-shell, change that

We want to make the extensions app code more self-contained to make it

libnm doesn't only search for plugins in the regular VPN plugin directory,

There are two ways for applications to provide a high contrast icon:
1. install an icon into the HighContrast theme
2. install a symbolic icon into the default hicolor theme
The latter is preferred nowadays, and implemented in the high-contrast
CSS variant by enforcing the symbolic icon style.
However together with the way we currently enable/disable high-contrast,
this can lead to the following race:
1. the GTK theme is changed from HighContrast
2. we reload the default stylesheet
3. the icon style changes to "regular", so we request a
new icon from the HighContrast icon theme
4. the icon theme is changed from HighContrast
5. we evict existing icons from the cache
6. we reload icons for the new icon theme; however as we
find a pending request (from 3), we re-use it
7. the request from 3 finishes, and we end up with a
wrong icon in the cache
The simplest fix is to change the icon theme before the GTK theme: Unlike the
theme name, the icon style is encoded in the cache key, so we won't re-use
an old (and incorrect) request in that case.

- as evolution can now be distributed via flatpak, we can no longer
assume that 'evolution-calendar.desktop' exists when evolution does
(even though we ship the .desktop file ourselves, it is considered
invalid if the executable isn't found)

At least for the time being, this looks like the easiest option to
launch the service:
- we could add a systemd unit, but then we'd need to update the
RequiredComponents in the fallback session definition as well,
making it necessary for gnome-shell, gnome-shell-extensions and
gnome-session to be updated to 3.36.1 in lockstep
- autostart is problematic as it would make gnome-shell conflict
with other notification daemons; also autostart is most useful
with automatic shutdown, which would require tracking signal
subscriber to determine when the service is unused

Add a small service that exposes the Fdo notification API under the

There are a couple of D-Bus services that are currently provided by

This caches GAppInfo so that the compositor thread does not have to perform
costly disk access to load them. Instead, they are loaded from a worker
thread and the ShellAppCache notifies of changes.
To simplify maintenance, ShellAppCache manages this directly and the
existing ShellAppSystem wraps the cache. We may want to graft these
together in the future, but now it provides the easiest way to backport
changes to older Shell releases.
Another source of compositor thread disk access was in determining the
name for an application directory. Translations are provided via GKeyFile
installed in "desktop-directories". Each time we would build the name
for a label (or update it) we would have to load all of these files.
Instead, the ShellAppCache caches that information and updates the cache
in bulk when those change. We can reduce this in the future to do less
work, but chances are these will come together anyway so that is probably
worth fixing if we ever come across it.

These paths are meant for Xwayland, not for X11 compositors being restarted

Since the FolderViews are not connected to the "installed-changed"
signal, we need to reload their apps by calling _redisplay() when an app
is removed or installed. We can't connect to "installed-changed" inside
FolderView because we need to ensure _redisplay() of the FolderView is
called before AppView tries to access the apps of the folder inside
_refilterApps(). So reload the FolderViews inside AllViews _redisplay()
implementation to ensure everything is up to date before accessing the
apps of the folder.
Since the "apps-changed" signal of FolderIcon now indirectly triggers a
_redisplay() of the FolderViews, the 'changed' handler of FolderView is
now redundant and can be removed. Because of this, we also need to move
the emission of the "apps-changed" signal to the start of the signal
handler to make sure the view is updated before we try to access items
of the view.

The _redisplay() function is usally used for subclasses of BaseAppView

functions _sync() and _rebuildMenu() instead.

The viewBox has a border applied, so when we call adaptToSize using only
the content box of the container, the width of the border is not removed
from the content box and the grid will be allocated less space than what
we told it before using adaptToSize.
Fix that by adjusting the content box for the size of the viewBox, too.
This makes sure the correct amount of columns can be shown inside a

Since 38da479ee we correctly ceil the non-integer radius of the slider

Unlike any other methods in the Extensions API, LaunchExtensionPrefs()
opens what appears to be an application dialog, except that it is
really a separate application that the caller has no control over.
In order to address that, add a new OpenExtensionPrefs() method that

that will make it possible to improve the behavior in the future.
The new parameters are ignored for now, but pushing the API out now
will allow us to fill in the functionality post the .0 release.

This (mistakenly) now only depends on signals triggered on Wayland
sessions. Hardcoding the XIM support on X11 sessions will make input

Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1690
Currently, a failure to start the Systemd unit `gsd-xsettings.target`
would be considered a failure to start Xwayland.
That means that if `gsd-xsettings.target` fails to start for whatever
reason, no X11 client can be used on Wayland.
However, XSettings is by no mean mandatory for X11 clients and many
legacy X11 clients do not implement XSettings. Those who do always have
a fallback path and therefore can still work without XSettings.
Make a failure to start the Systemd unit `gsd-xsettings.target` non
blocking for Xwayland, and just log a warning message.

We ended up always showing the switch-user button on the lock screen,
as showing and hiding it with the prompt was too visually distracting.
But now that we have a fancy transition in place, we can easily extend
it to the switch-user button as well.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/1029
We only call _updateSensitivity() to make elements sensitive, and
nothing ever touches the sensitivity of the switch-user button; so
just call the corresponding authPrompt method directly, which is the
only bit that has an actual effect.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/1029
We do spawn gsd-xsettings, and watch its name before notifying on the
given task, so the mutter bits can proceed with X11 startup.
One notable change is that we only start gsd-xsettings, instead of the
generic gnome-session-x11-services target. We do so as we have to wait
on a dbus name to appear in order to deem the initialization done, and
making it all depend on gsd-xsettings seems tidier.
Less notably, we also use ::shutdown-xserver to shutdown the related
services. Its major benefit is that it'd allow us to ensure the olderly
shutdown of those services, but it's unused at the moment.

When a window is being resized by the compositor, with Wayland the
compositor first asks the window to change its size and emits the
"size-change" signal, and then emits the "size-changed" signal after
the window acknowledges the new size. To show a fancy resize animation,
gnome-shell creates a "screenshot" of the resizing window on the
"size-change" signal, and later animates that "screenshot" to the new
window size on the "size-changed" signal.
Now if a client is not responding to our requests asking it to change
its size, we get a "size-change" signal and start showing the
window-clone, but never a "size-changed" signal, animating and hiding
the clone again. This causes a so called "ghost window" that is shown
above everything else and never disappears again.
To fix that, start showing the window clone once we get the
"size-changed" signal instead of the "size-change" signal. This makes
sure the window actually updates its size and the clone is going to be
hidden again.

The thumbnails actor `this._thumbnails` has already been destroyed when

When the switcherPopup was initiated successfully, we return true,
otherwise the WindowManager will try to destroy it. Since an early

Right now the index that gets selected on click and motion events is set
when connecting the event inside the addItem function. If items are
added or removed (for example when an application is closed by pressing
"q"), this index isn't valid anymore and has to be updated.
To fix this, use the items themselves instead of the index as arguments
for the event handlers and lookup the index of the item inside the event
handler.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/167
Set the accessible states of the switcherList items by calling a
function instead of manipulating class-internal variables from outside
the class, which is considered bad practice.
The check whether the item at `_selectedIndex` exists can also be
removed since we always select a new index after an item was removed
(i.e. an app was closed) and destroy the alt-tab switcher right away if
no more items exist (see `SwitcherPopup._itemRemovedHandler`).

Limit the minimum and maximum value to scroll to inside the box to 0 and
the upper limit, for some reason this was done right in _scrollToRight,
but not in _scrollToLeft.
This fixes the behavior of scrolling to the left: Before, scrolling one
item to the left moved the view to the first element of the list (this
can make the selected element invisible in large lists). Instead, scroll
one item to the left, just like scrolling to the right works.

Make sure the index that's being scrolled to doesn't change while the
scrolling animation is running by using an argument instead of the
this._highlighed class scope variable.
This fixes wrongly shown arrows when selecting new elements faster than
the scrolling animation takes for one index. The check run to disable
the arrow might be checking against a newer index than the one at the
start of the animation which results in the arrow not getting hidden
even if no more scrolling is possible.

Since this._highlighted is always set to the currently highlighted
index, there's no need to save the index to a separate variable. This
obviously depends on getting the new item highlighted as a result of the
item-entered event.
This fixes bugs in situations where the highlighted element changes
after an event that is not calling _onItemEnter, for example after
scrolling or pressing a key. In those cases the _currentItemEntered
variable wouldn't be updated and the old item couldn't be entered
anymore without entering another one before.

If the sessionMode does not allow to show the overview, we should also

The button is hidden on the lock screen, so it shouldn't be allowed to

Since commit mutter/a2a8f0cda we force the focus surface of the
meta-wayland-pointer to NULL while the pointer is hidden. This
introduced an issue with the magnifier, where we use
`set_pointer_visible` to hide the real cursor and show our own cursor at
the correct position: Because the meta-wayland-pointer is still used to
communicate with Wayland clients, the UI of the windows will not respond
to mouse movement anymore as soon as the real cursor is hidden.
To fix this, use the newly added clutter_seat_inhibit_unfocus() API to
temporarily disable unsetting the focus-surface while the magnifier is
hiding the system cursor.

If we are transitioning the label from 0 to its natural height, we
must set natural-height-set again after querying the preferred height,
otherwise Clutter would skip the transition.
However when transitioning in the opposite direction, setting the
property to true can go horribly wrong:
If the actor hasn't been allocated before, it will store a fixed
natural height of 0. But as there is no fixed min-height, we can
end up with min-height > natural-height, which is a fatal error.
(This isn't an issue when *actually* setting a fixed height, as
that will set both natural and minimum height)
So instead of always setting natural-height-set to true, restore
its previous value to fix the issue.

repeatCount and autoReverse don't play well with animations disabled:
They cause password entries to wiggle themselves off-screen (by ending
up with some off-scale translation-x value).
While we should handle this more gracefully in the transition helpers,
it also makes sense to handle the case directly in wiggle(): As it
uses a chain of three transitions, we would still end up with a crude
one-frame-per-transition wiggle "animation".
Instead, do no animation at all as you would expect when animations are
disabled.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/2236
Now that we apply a strong blur effect to the background, it doesn't
make too much sense to use a separate lock-screen background: It will
be mostly unrecognizable anyway.
The alternative would be to turn off the blur effect if a different
background is used (or have a hidden setting for that), but that would
then imply that we must keep the contents readable without blur.
Let's avoid that rabbit hole and just re-use the regular background.

To bypass offscreening in cases where continuous animation is happening.
Offscreening is slower in such cases so this reduces the render time of

For reasons not yet fully understood, `Main.uiGroup.add_actor` takes around
10 milliseconds to complete.
Because of this, each `actor.opacity = 0` has a good chance of falling
on a different frame. And when it does, `_opacityChangedId` also lands
on multiple different frames each incurring a separate relayout cycle.
It is this excessive number of relayouts that causes stuttering in the
icon grid animation (#2065). But it is the slowness of `uiGroup.add_actor`
that causes the number to be excessive when it should be one.
By creating the clones and adding them to `uiGroup` early, we then enable
the existing loop starting the animation to complete within a single frame.
And by completing within a single frame all the opacity changes land within
the same frame interval, thus incurring only a single relayout instead of
many.
This issue went unnoticed until 004a5e1042 (!704), after which the slow
emissions of `notify::opacity` became a more visible performance problem.

Now that the bind constraint changes the preferred size of
the actor, a major flaw in the AppDisplay code was exposed:
the folder dialog depends on the preferred size of a parent,
and the parent depends on the preferred size of the folder
dialog.
While we know this is not actually true, we shouldn't rely
on broken behavior to achieve this result. What's interesting
is that the bind constraint used by the folder dialog is a
relic of the development phase; we now control the position
and size of the dialog with a combination of CSS, and alignment.
Remove the unnecessary bind constraint.

To make sure the GC really disposes the KeyboardController object we
