std commands can block for an arbitrary duration and so runs risk of
blocking tasks for too long. This replaces all such uses where sensible
with async processes.

We noticed this PR causes the editor to hang if you hold down any of the
menu item actions like ctrl+z, ctrl+x, etc
Release Notes:
- Fixed macOS menu item actions hanging the editor when their key
combination is held down
On macOS, traditionally when a keyboard shortcut is activated, the menu
in the menu bar flashes to indicate that the action was recognised.

This PR adds this functionality to GPUI, where when a keybind is pressed
that triggers an action in the menu, the menu flashes.

Extracts and cleans up GPUI's scheduler code into a new `scheduler`
crate, making it pluggable by external runtimes. This will enable
deterministic integration testing with cloud components by providing a
unified test scheduler across Zed and backend code. In Zed, it will
replace the existing GPUI scheduler for consistent async task management
across platforms.
## Changes
- **Core Implementation**: `TestScheduler` with seed-based
randomization, session tracking (`SessionId`), and foreground/background
task separation for reproducible testing.
- **Executors**: `ForegroundExecutor` (!Send, thread-local) and
`BackgroundExecutor` (Send, with blocking/timeout support) as
GPUI-compatible wrappers.
- **Clock and Timer**: Controllable `TestClock` and future-based `Timer`
for time-sensitive tests.
- **Testing APIs**: `once()`, `with_seed()`, and `many()` methods for
configurable test runs.
- **Dependencies**: Added `async-task`, `chrono`, `futures`, etc., with
updates to `Cargo.toml` and lock file.
## Benefits
- **Integration Testing**: Facilitates reliable async tests involving
cloud sessions, reducing flakiness via deterministic execution.
- **Pluggability**: Trait-based design (`Scheduler`) allows easy
integration into non-GPUI runtimes while maintaining GPUI compatibility.
- **Cleanup**: Refactors GPUI scheduler logic for clarity, correctness
(no `unwrap()`, proper error handling), and extensibility.
Follows Rust guidelines; run `./script/clippy` for verification.
- [x] Define and test a core scheduler that we think can power our cloud
code and GPUI
- [ ] Replace GPUI's scheduler

Previously, we were using `PostThreadMessage` to pass messages to
`WindowsPlatform`. This PR switches to an approach similar to `winit`
which using a hidden window as the message window (I guess that’s why
winit uses a hidden window?). The difference is that this PR creates it
as a message-only window.
Thanks to @reflectronic for the original PR #37255, this implementation
just fits better with the current code style.

This improves font rendering quality by doing perceptual gamma+contrast
correction which makes font edges look nicer and more legible.

This is most noticeable on smaller fonts / low-dpi displays
Release Notes:
- Improved font rendering quality
Closes#36300
This PR follows Windows conventions by introducing
`KeybindingKeystroke`, so shortcuts now show up as `ctrl-shift-4`
instead of `ctrl-$`.
It also fixes issues with keyboard layouts: when `use_key_equivalents`
is set to true, keys are remapped based on their virtual key codes. For
example, `ctrl-\` on a standard English layout will be mapped to
`ctrl-ё` on a Russian layout.

Closes#24672
This PR complements a feature added earlier by @JosephTLyons (in
https://github.com/zed-industries/zed/pull/32353) where the text is
considered as the tab title in a new buffer. It piggybacks off that
change and sets the title as the suggested filename in the save dialog
(completely mirroring the same functionality in VSCode):

Release Notes:
- Text entered in a new untitled buffer is considered as the default
filename when saving
Closes#34374
This is a leftover issue from #34374. Back in #34374, I wanted to use
DirectX to handle vsync, after all, that’s how 99% of Windows apps do
it. But after discussing with @maxbrunsfeld , we decided to stick with
the original vsync approach given gpui’s architecture.
In my tests, there’s no noticeable performance difference between this
PR’s approach and DirectX vsync. That said, this PR’s method does have a
theoretical advantage, it doesn’t block the main thread while waiting
for vsync.
The only difference is that in this PR, on Windows 11 we use a newer API
instead of `DwmFlush`, since Chrome’s tests have shown that `DwmFlush`
has some problems. This PR also removes the use of
`MsgWaitForMultipleObjects`.

This PR doesn't change any logic, it just cleans up some naming and
style in the windows platform layer.
* Rename `WindowsWindowStatePtr` to `WindowsWindowInner`, since it isn't
a pointer type.
* Move window event handler methods into an impl on this type, so that
all of the `state_ptr: &Rc<WindowsWindowInner>` parameters can just be
replaced with `&self`.
* In window creation, use a `match` instead of a conditional followed by
an unwrap
There's a lot of whitespace in the diff, so view it with `w=1`.

Instead of selecting a screen to share arbitrarily, we'll now allow user
to select the screen to share. Note that sharing multiple screens at the
time is still not supported (though prolly not too far-fetched).

This PR improves key handling on Windows by moving the
`TranslateMessage` call from the message loop to after we handled
`WM_KEYDOWN`. This brings Windows behavior more in line with macOS and
gives us finer control over key events. As a result, Vim keybindings now
work properly even when an IME is active. The trade-off is that it might
introduce a slight delay in text input.
Release Notes:

https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`

This PR adds a new `PlatformKeyboardLayout` trait with two methods:
`id(&self) -> &str` and `name(&self) -> &str`. The `id()` method returns
a unique identifier for the keyboard layout, while `name()` provides a
human-readable name. This distinction is especially important on
Windows, where the `id` and `name` can be quite different. For example,
the French layout has an `id` of `0000040C`, which is not
human-readable, whereas the `name` would simply be `French`. Currently,
the existing `keyboard_layout()` method returns what's essentially the
same as `id()` in this new design.
This PR implements the `name()` method for both Windows and macOS. On
Linux, for now, `name()` still returns the same value as `id()`.
Release Notes:

While working on implementing `add_recent_documents` for Windows, I
found that the process is significantly more complex compared to macOS.
On macOS, simply registering the `add_recent_documents` function is
enough, as the system handles everything automatically.
On Windows, however, there are two cases to consider:
- **Files opened by the app**: These appear in the "Recent" section (as
shown in the screenshot, "test.txt") and are managed automatically by
Windows (by setting windows registry), similar to macOS.

- **Folders opened by the app**: This is more complicated because
Windows does not handle it automatically, requiring the application to
track opened folders manually.
To address this, this PR introduces a `History Manager` along with
`HistoryManagerEvent::Update` and `HistoryManagerEvent::Delete` events
to simplify the process of managing recently opened folders.

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 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.

There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures
- [x] Mac build issue

Closes#22653 again
In PR #23283, I thought that every `runnable` dispatched to the main
thread would correspond to an `EVENT_DISPATCHED` message in the message
queue. However, after testing, some `runnable`s occasionally weren’t
executed.
This PR updated the code as follows:
```rust
if let Ok(runnable) = self.main_receiver.try_recv() { <-- before
for runnable in self.main_receiver.drain() { <-- after
runnable.run();
}
```
This ensures that runnables are handled more proactively on the main
thread, now we handle `runnable`s with a much higher priority.
A big thanks to @MolotovCherry and @ArthurBrussee for their testing
efforts!
