While `scap` does have support for Wayland and Windows, but haven't seen
screensharing work properly there yet. So for now just adding support
for X11 screensharing.
WIP branches for enabling wayland and windows support:
* https://github.com/zed-industries/zed/tree/wayland-screenshare
* https://github.com/zed-industries/zed/tree/windows-screenshare
Release Notes:
- Added support for screensharing on X11 (Linux)

Closes#4461
Take 2 on https://github.com/zed-industries/zed/pull/25040.
Fixes panic caused due to using `setHiddenUntilMouseMoves` return type
to `set` cursor on macOS.
Release Notes:
- Now cursor hides when the user is typing in editor. It will stay
hidden until it is moved again. This behavior is `true` by default, and
can be configured with `hide_mouse_while_typing` in settings.

This reverts commit a8610fbd13.
I've been seeing some reports of segmentation faults that appear to
point to this change as the culprit.
Closes#25366.
Release Notes:
- Community: Reverted #25040, so remove the corresponding entry from the
release notes.
Closes https://github.com/zed-industries/zed/issues/4461
This PR improves the coding experience by hiding the mouse while the
user is typing so it does not accidentally get in their way, making it
challenging to ready characters in the editor.
Release Notes:
- The following PR hides the cursor when the user is typing by adding a
new cursor style called `None`.
- Assuming the user does not move the mouse, it will stay hidden until
it is moved again.

Closes#24139
For weird reasons, Sway on few linux distoros sends `NoKeymap` event when
switching windows. Zed crashes due to assertion on this event to be `XkbV1`.
To fix this, we ignore `NoKeymap` event instead crashing Zed.
Release Notes:
- Fixed a crash in Wayland-based compositors like Sway when switching windows via the keyboard.
No issue, as the functionality is currently not being used in Zed. This
is more of a GPUI improvement.
Currently, `keyboard_layout` and `on_keyboard_layout_change` are already
handled on macOS. This PR implements the same for X11 and Wayland.
Linux supports up to 4 keyboard layout groups (e.g., Group 0: English
US, Group 1: Bulgarian, etc). On X11 and Wayland, `event` provides a new
active group, which maps to the `layout_index`. We already store keymap
state from where we can get the current `layout_index`. By comparing
them, we determine if the layout has changed.

Closes#17005
Release Notes:
- Improved GPU context management: share a single context with multiple
surfaces.
### High Level
Blade got a proper support for Surface objects in
https://github.com/kvark/blade/pull/203.
That was mainly motivated by Zed needing to draw multiple windows. With
the Surface API, Zed is now able to have the GPU context tied to the
"Platform" instead of "Window". Practically speaking, this means:
- architecture more sound
- faster to open/close windows
- less surprises, more robust
### Concerns
1. Zed has been using a temporary workaround for the platform bug on
some Intel+Nvidia machines that makes us unable to present -
https://github.com/kvark/blade/pull/144 . This workaround is no longer
available with the new architecture. I'm looking for ideas on how to
approach this better.
- we are now picking up the change in
https://github.com/kvark/blade/pull/210, which allows forcing a specific
Device ID. This should allow Zed users to work around the issue. We
could help them to automate it, too.
2. ~~Metal-rs dependency is switched to
https://github.com/kvark/metal-rs/tree/blade, since upstream isn't
responsive in merging changes that are required for Blade. Hopefully,
temporary.~~
- ~~we can also hack around it by just transmuting the texture
references, since we know those are unchanged in the branch. That would
allow Blade to use it's own version of Metal, temporarily, if switching
metal-rs in the workspace is a concern.~~
- merged my metal-rs changes and updated Zed to use the upstream github
reference

Closes#15788, #13258
This is a long-standing issue with a few previous attempts to fix it,
such as [this one](https://github.com/zed-industries/zed/pull/17496).
However, that fix was later reverted because it resolved the blur issue
but caused a size issue. Currently, both blur and size issues persist
when you set a custom cursor size from GNOME Settings and use fractional
scaling.
This PR addresses both issues.
---
### Context
A new Wayland protocol,
[cursor-shape-v1](https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/194),
allows the compositor to handle rendering the cursor at the correct size
and shape. This protocol is implemented by KDE, wlroots (Sway-like
environments), etc. Zed supports this protocol, so there are no issues
on these desktop environments.
However, GNOME has not yet
[adopted](https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/6212) this
protocol. As a result, apps must fall back to manually rendering the
cursor by specifying the theme, size, scale, etc., themselves. Zed also
implements this fallback but does not correctly account for the display
scale.
---
### Scale Fix
For example, if your cursor size is `64px` and you’re using fractional
scaling (e.g., `150%`), the display scale reported by the window query
will be an integer value, `2` in this case. Why `2` if the scale is
`150%`? That’s what the new protocol aims to improve. However, since
GNOME Wayland uses this integer scale everywhere, it’s sufficient for
our use case.
To fix the issue, we set the `buffer_scale` to this value. But that
alone doesn’t solve the problem. We also need to generate a matching
theme cursor size for this scaled version. This can be calculated as
`64px` * `2`, resulting in `128px` as the theme cursor size.
---
### Size Fix
The XDG Desktop Portal’s `cursor-size` event fails to read the cursor
size because it expects an `i32` but encounters a type error with `u32`.
Due to this, the cursor size was interpreted as the default `24px`
instead of the actual size set via user.
---
### Tested
This fix has been tested with all possible combinations of the
following:
- [x] GNOME Normal Scale (100%, 200%, etc.)
- [x] GNOME Fractional Scaling (125%, 150%, etc.)
- [x] GNOME Cursor Sizes (**Settings > Accessibility > Seeing**, e.g.,
`24px`, `64px`, etc.)
- [x] GNOME Experimental Feature `scale-monitor-framebuffer` (both
enabled and disabled)
- [x] KDE (`cursor-shape-v1` protocol)
---
**Result:**
64px custom cursor size + 150% Fractional Scale:
https://github.com/user-attachments/assets/cf3b1a0f-9a25-45d0-ab03-75059d3305e7
---
Release Notes:
- Fixed mouse cursor size and blur issues on Wayland
As part of the recent changes to keyboard support, ime_key is no longer
populated by the IME; but instead by the keyboard.
As part of #20877 I changed some code to assume that falling back to key
was
ok, but this was not ok; instead we need to populate this more similarly
to how
it was done before #20336.
The alternative fix could be to instead of simulating these events in
our own
code to push a fake native event back to the platform input handler.
Closes #ISSUE
Release Notes:
- Fixed a bug where tapping `shift` coudl type "shift" if you had a
binding on "shift shift"
Closes#17771
Reverts zed-industries/zed#17496
This PR turns out to need more work than I thought when I merged it.
Release Notes:
- Linux: Fix a bug where the cursor would be the wrong size on Wayland
Closes #14089, #14416, #15970, #17230, #18485
Release Notes:
- Fixed some cases where Linux X11 mouse scrolling doesn't work at all
(#14089, ##15970, #17230)
- Fixed handling of switching between Linux X11 devices used for
scrolling (#14416, #18485)
Change details:
Also includes the commit from PR #18317 so I don't have to deal with
merge conflicts.
* Now uses valuator info from slave pointers rather than master. This
hopefully fixes remaining cases where scrolling is fully
broken. https://github.com/zed-industries/zed/issues/14089,
https://github.com/zed-industries/zed/issues/15970,
https://github.com/zed-industries/zed/issues/17230
* Per-device recording of "last scroll position" used to calculate
deltas. This meant that swithing scroll devices would cause a sudden
jump of scroll position, often to the beginning or end of the
file (https://github.com/zed-industries/zed/issues/14416).
* Re-queries device metadata when devices change, so that newly
plugged in devices will work, and re-use of device-ids don't use old
metadata with a new device.
* xinput 2 documentation describes support for multiple master
devices. I believe this implementation will support that, since now it
just uses `DeviceInfo` from slave devices. The concept of master
devices is only used in registering for events.
* Uses popcount+bit masking to resolve axis indexes, instead of
iterating bit indices.

This PR fixes two issues:
1. The prompt library window didn't set an `app_id` on Linux, which
caused it to be missing the Zed logo
2. A dangling reference to the window in the Wayland client code, which
caused the prompt library window not to close. See:

Closes#14415
(also removed an unused serial while I was at it)
Release Notes:
- Linux: Fixed cross-window copy/paste not working in some Wayland
configurations.
This changes the workspace/session serialization to also persist the
order of windows across restarts.
Release Notes:
- Improved restoring of windows across restarts: the order of the
windows is now also restored. That means windows that were in the
foreground when Zed was quit will be in the foreground after restart.
(Right now only supported on Linux/X11, not on Linux/Wayland.)
Demo:
https://github.com/user-attachments/assets/0b8162f8-f06d-43df-88d3-c45d8460fb68
This restores https://github.com/zed-industries/zed/pull/13943 which was
reverted in #13974 because it was possible to get in a state where focus
could not be restored on a window.
In this PR there's an additional change: `FocusIn` and `FocusOut` events
are always handled, even if the `event.mode` is not "NORMAL". In my
testing, `alt-tabbing` between windows didn't produce `FocusIn` and
`FocusOut` events when we had that check. Now, with the check removed,
it's possible to switch focus between two windows again with `alt-tab`.

This PR consists of two main changes:
1. The first commit changes the `open` crate for opening URLs/paths for
the `OpenURI` desktop portal. This fixes the activation token not being
passed to programs (at least on KDE).
2. The second commit implements the window `activate()` API on Wayland.
This allows KWin and Mutter to show a visual indicator when the window
is requesting attention. (see

This changes the implementation of the X11 client to use `mio`, as a
polling mechanism, and a custom run loop instead of `calloop` and its
callback-based approach.
We're doing this for one big reason: more control over how we handle
events.
With `calloop` we don't have any control over which events are processed
when and how long they're processes for. For example: we could be
blasted with 150 input events from X11 and miss a frame while processing
them, but instead of then drawing a new frame, calloop could decide to
work off the runnables that were generated from application-level code,
which would then again cause us to be behind.
We kinda worked around some of that in
https://github.com/zed-industries/zed/pull/12839 but the problem still
persists.
So what we're doing here is to use `mio` as a polling-mechanism. `mio`
notifies us if there are X11 on the XCB connection socket to be
processed. We also use its timeout mechanism to make sure that we don't
wait for events when we should render frames.
On top of `mio` we now have a custom run loop that allows us to decide
how much time to spend on what — input events, rendering windows, XDG
events, runnables — and in what order we work things off.
This custom run loop is consciously "dumb": we render all windows at the
highest frame rate right now, because we want to keep things predictable
for now while we test this approach more. We can then always switch to
more granular timings. But considering that our loop runs and checks for
windows to be redrawn whenever there's an event, this is more an
optimization than a requirement.
One reason for why we're doing this for X11 but not for Wayland is due
to how peculiar X11's event handling is: it's asynchronous and by
default X11 generates synthetic events when a key is held down. That can
lead to us being flooded with input events if someone keeps a key
pressed.
So another optimization that's in here is inspired by [GLFW's X11 input
handling](b35641f4a3/src/x11_window.c (L1321-L1349)):
based on a heuristic we detect whether a `KeyRelease` event was
auto-generated and if so, we drop it. That essentially halves the amount
of events we have to process when someone keeps a key pressed.

The KeyEnter serial will be too old if another client replaces the
selection before the user unfocuses and refocuses the window (i.e.,
triggers another KeyEnter event).
The KeyPress event is more likely to be new enough.
Release Notes:
- Fixed setting clipboard sometimes not working on wayland
([#13445](https://github.com/zed-industries/zed/issues/13445)).
Fixes https://github.com/zed-industries/zed/issues/12054
Replaces the `copypasta`/`smithay-clipboard` implementation with a new,
custom one
TODO list:
- [x] Cleanup code
- [x] Remove `smithay-clipboard`
- [x] Add more mime types to the supported list
Release Notes:
- Fixed drag and drop on Gnome
- Fixed clipboard paste on Hyprland
On most platforms, things were working correctly, but had the wrong
type. On X11, there were some problems with window and display size
calculations.
Release Notes:
- Fixed issues with window positioning on X11

This PR adds support for `org.gnome.desktop.interface`'s `cursor-theme`
setting on Wayland. This should fix cursors not showing up on some GNOME
installs. This PR also adds the wiring to watch the current cursor theme
value.
Thanks to @apricotbucket28 for helping debug the issue.
Release Notes:
- N/A
TODO:
- [x] Finish GPUI changes on other operating systems
This is a largely internal change to how we report data to our
diagnostics and telemetry. This PR also includes an update to our blade
backend which allows us to report errors in a more useful way when
failing to initialize blade.

This change ensures that the event loop prioritizes enqueueing another
render or handling user input over executing runnables.
It's a subtle change as a result of a week of digging into performance
on X11. It's also not perfect: ideally we'd get rid of the intermediate
channel here and had more control over when and how we run runnables vs.
X11 events, but I think short of rewriting how we use an event loop,
this is good cost/benefit change.
To illustrate:
Before this change, it was possible to block the app from rendering for
a long time by just creating a ton of futures that were executed on the
"main" thread (we don't have a "main" thread on Linux, but we have a
single thread in which we run the event loop).
That was relatively easy to reproduce by opening the `zed` repository
and starting `rust-analyzer`: at some point `rust-analyzer` sends us so
many notifications, that are all handled in futures, that the event loop
is busy just working off the runnables, never getting to the events that
X11 sends us or our own timer to re-enqueue another render.
When you put print statements into the code to show when which event was
handled, you'd see something like this **before this change**:
```

```
Note the `lag: 56ms`: that's the difference between when we wanted to
execute the callback that enqueues another render and when it ran.
Longer lags are possible, this is just the first one I grabbed from the
logs.
Now, compare this with the logs **after this change**:
```

```
In-between many `runnable.run()` we'll always handle events.
So, in essence, what this change does is to introduce 2 priorities into
the X11 event queue:
- high: X11 events (user events, render events, ...), render tick, XIM
events, ...
- low: all async rust code
I've tested this with a debug build and release build and I think the
app now feels more responsive. It doesn't feel perfect still, especially
in the slow debug builds, but I couldn't observe 10s lockups anymore.
Since it's a pretty small change, I think we should go for it and see
how it behaves.
Thanks to @maan2003 this now also includes the same change to Wayland.

Fixes multiple issues that prevented window bounds restoration to not
work on Wayland.
Note: Since the display uuid depends on the `wl_output.name` field, this
only works properly on KDE 5.26+ or Gnome 44+ ([kwin
commit](330a02d862),
[mutter](7e838b1115)).

Fixes#12198 and some minor fixes:
* IBus was intercepting normal keys like `a`, `k` which caused some
problems in vim mode.
* Wayland: Trying to commit the pre_edit on click wasn't working
properly, should be fixed now.
* X11: The pre_edit was supposed to be cleared when losing keyboard
focus.
* X11: We should commit the pre_edit on click.
