This reverts commit ed7bd5a8ed.
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.

that triggers an action in the menu, the menu flashes.

Closes https://github.com/zed-industries/zed/issues/37621
Improves https://github.com/zed-industries/zed/issues/24623
Adding scrollbars withing Zed's UI currently is rather cumbersome, as it
requires the copying of a lot of code in order for these to work. Wiring
up settings for scrollbar visibilty always has to be done at the call
site and the state has to be saved and maintained by the caller as well.
Similarly, reserving space has to also be handled by the caller.
This PR changes the way scrollbars work in Zed fundamentally by making
use of the new `use_keyed_state` APIs: Instead of saving the state at
the call site, the window now keeps track of the state corresponding to
scrollbars. This enables us to add scrollbars with e.g. one simple call
on divs:
```rust
div()
.vertical_scrollbar(window, cx)
```
will add a scrollbar to the corresponding container. There are some more
improvements regarding tracking of scrollbar visibility settings (which
is now handled by a trait for each setting that supports this) as well
as reserving space.
Additionally, all needed stuff for layouting, catching events and
reserving space is also now managed by the scrollbar component instead.
This drastically reduces the amount of event listeners and makes
layouting of two scrollbars easier.
Furthermore, this paves the way for more improvements to scrollbars,
such as graceful auto-hide. Only downsight here is that we lose some
customizability in a few areas. However, once this lands, we gain the
ability to quickly follow these up without breaking stuff elsewhere.
This also already fixes a few bugs:
- Scrollbars no longer flicker on first render.
- Auto-hide now properly works for all scrollbars.
- If the content size changes, the scrollbar is updated on the same
frame. Both of these happened because we were computing the scrollbar
sizes too early, causing us to use the sizes from the previous frame or
unitialized sizes.
- The project panel no longer jumps if scrolled all the way to the
bottom and the scrollbar actually auto-hides.
Still TODO:
- [x] Fix scrolling in the debugger memory view
- [x] Clean up some more in the scrollbar component and reduce clones
there
- [x] Ensure we don't over-notify the entity the scrollbar is rendered
within
- [x] Make sure auto-hide properly works for all cases
- [x] Check whether we want to implement the scrollbar trait for
`UniformList`s as well
- ~~ [ ] Use for uniformlist where possible~~ Postponed
- [x] Improve layout for cases where we render both scrollbars.

After this the doctests will be run in CI to check that the examples are
still accurate.
Note that doctests aren't run by Nextest: you can run them locally with
`cargo test --doc`.
Summary:
* Run tests from CI
* Loosen an exact float comparison to match approximately (otherwise it
fails)
* Fixed one actual bug in the tests for `dilate` where the test code
assumed that `dilate` mutates `self` rather than returning a new object
* Add some `must_use` on some functions that seemed at risk of similar
bugs, following the Rust stdlib style to add it where ignoring the
result is almost certainly a bug.
* Fix some cases where the doc examples seem to have gone out of date
with the code
* Add imports to doctests that need them
* Add some dev-dependencies to make the tests build
* Fix the `key_dispatch` module docstring, which was accidentally
attached to objects within that module
* Skip some doctest examples that seem like they need an async
environment or that just looked hard to get running
AI usage: I asked Claude to do some of the repetitive tests. I checked
the output and fixed up some things that seemed to not be in the right
spirit of the test, or too longwinded.
I think we could reasonably run the tests on only Linux to save CI
CPU-seconds and latency, but I haven't done that yet, partly because of
how it's implemented in the action.
Release Notes:
- N/A
This is an initial implementation that isn't used for any settings yet,
but will be used once `Vec<String>` is implemented.
I also updated the window.with_state api to grant access to a
`Context<S>` app reference instead of just an App.

Removes IME bounds scaling on Wayland since it uses logical pixels,
unlike X11. We now scale only on X11. Windows and macOS don’t use these
bounds for IME anyway.
Release Notes:
- Fixed an issue where the IME popover could appear outside the window
or fail to show on Wayland.
This reverts commit 40199266b6.
The issue with the commit is: ContentMask<Pixels>::intersect is doing
intersection of corner radii which makes inner containers use the max
corner radius out of all the parents when it should be more complex to
correctly clip children (clip sorting..?)

The only warnings remaining are links to private modules/items, but I
lack knowledge to work out if the referenced modules/items should be
made public, or if the links should be rewritten into exposed
traits/items.
Links to associated items such as trait implementations have to be
written using full markdown format such as:
... [[ `App::update_global` ]](( BorrowAppContext::update_global ))
This is due to https://github.com/rust-lang/rust/issues/74563 which
sadly prohibits fully-qualified syntax:
... [[ `<App as BorrowAppContext>::update_global` ]]

Follow up of https://github.com/zed-industries/zed/pull/33334
After chatting with @MrSubidubi we found out that he had an old defaults
setting (most likely from when he encountered a previous window tabbing
bug):
```
❯ defaults read dev.zed.Zed-Nightly
{
NSNavPanelExpandedSizeForOpenMode = "{800, 448}";
NSNavPanelExpandedSizeForSaveMode = "{800, 448}";
NSNavPanelExpandedStateForSaveMode = 1;
NSOSPLastRootDirectory = {length = 828, bytes = 0x626f6f6b 3c030000 00000410 30000000 ... dc010000 00000000 };
"NSWindow Frame NSNavPanelAutosaveName" = "557 1726 800 448 -323 982 2560 1440 ";
"NSWindowTabbingShoudShowTabBarKey-GPUIWindow-GPUIWindow-(null)-HT-FS" = 1;
}
```
> That suffix is AppKit’s fallback autosave name when no tabbing
identifier is set. It encodes the NSWindow subclass (GPUIWindow), plus
traits like HT (hidden titlebar) and FS (fullscreen).
Which explains why it only happened on the Nightly build, since each
bundle has it's own defaults. It also explains why the tabbar would
disappear when he activated the `use_system_window_tabs` setting,
because with that setting activated, the tabbing identifier becomes
"zed" (instead of the default one when omitted) for which he didn't have
the `NSWindowTabbingShoudShowTabBarKey` default.
The original implementation was perhaps a bit naive and relied fully on
macOS to determine if the tabbar should be shown. I've updated the code
to always hide the tabbar, if the setting is turned off and there is
only 1 tab entry.
While testing, I also noticed that the menu's like 'merge all windows'
wouldn't become active when the setting was turned on, only after a full
workspace reload. So I added a setting observer as well, to immediately
set the correct window properties to enable all the features without a
reload.

This PR fixes two bugs and also changes one behavior in the **Keymap
Editor**.
As shown in the video, when I press `ctrl-shift-2` in the Keymap Editor,
the first keystroke is displayed as `ctrl-shift-@`, which is incorrect.
On macOS and Linux, it should be `ctrl-@`.
https://github.com/user-attachments/assets/69cfcfa0-b422-45d6-8e69-80f8608180fd
Also, after pressing `ctrl-shift-2` and then releasing `2` and `ctrl`, a
`shift` keystroke was incorrectly added.
https://github.com/user-attachments/assets/892124fd-847d-4fde-9b20-a27ba49ac934
Now, when you enter a sequence like `+ctrl+alt-alt+f` in the Keymap
Editor, it will output `ctrl-f` instead of `ctrl-alt-f`, matching VS
Code’s behavior.
Release Notes:
- Fixed incorrect keystroke reporting in the Keymap Editor.
This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.

Allows tabbing through everything in all three pages. Until #35075 is
merged it is not possible to actually "click" tab focused buttons with
the keyboard.
Additionally adds an action `onboarding::Finish` and displays the

We've noticed some issues with Zed on Intel-based Macs where typing has
become sluggish, and git bisect has seemed to point towards this PR.
Reverting for now, until we can understand why it is causing this issue.
Closes #ISSUE
`cx.intercept_keystrokes` functions as a sibling API to
`cx.observe_keystrokes`. Under the hood the two API's are basically
identical, however, `cx.observe_keystrokes` runs _after_ all event
dispatch handling (including action dispatch) while
`cx.intercept_keystrokes` runs _before_. This allows for
`cx.stop_propagation()` calls within the `cx.intercept_keystrokes`
callback to prevent action dispatch.
The motivating example usage behind this API is also included in this
PR. It is used as part of a keystroke input component that needs to
intercept keystrokes before action dispatch to display them.

Currently, the rendering path required creating a texture for each path,
which wasted a large amount of video memory. In our application, simply
drawing some charts resulted in video memory usage as high as 5G.
I removed the step of creating path textures and directly drew the paths
on the rendering target, adding post-processing global multi-sampling
anti-aliasing. Drawing paths no longer requires allocating any
additional video memory and also improves the performance of path
rendering.

Implements a chunking strategy for the element arena that allows it to
grow dynamically based on allocations, it is initialised with a single
chunk of a total size of 1 mebibyte. On allocation of data with a size
greater than the remaining space of the current chunk a new chunk is
created.
This reduces the memory allocation from the static 32 mebibytes, this
especially helps GPUI applications that don't need such a large element
arena and even Zed in most cases. This also prevents the panic when
allocations ever exceed the element arena.

This is an easy way to shave some microseconds off the critical path for
frame rendering. On my machine this reduces typical frame rendering
latency by ~100 microseconds, probably quite a bit more on slower
machines.
Here is how long it typically takes to drop elements from the arena,
from a fairly brief run:

For me this is a panic that started occurring today in my use of Zed.
The repro is to type `ctrl-x` to start a pending key sequence and then
close the collab side panel with the mouse. The issue is that
dispatching the action based on pending keystrokes uses the same
`DispatchNodeId` as when the 1 second timer was started.
`DispatchNodeId` is not stable across frames. This also means that the
wrong `DispatchNodeId` can be used in the non-panicing case, potentially
causing the action to not occur.
The mystery here is why did this only start happening now in my use of
Zed, and why isn't it showing up in the panics dashboard / issue
reports.
Panic looks like

Closes#32592
Follow-up to #31965
This PR fixes the cursor style flickering on Linux systems. The issue
arose since the window cursor style was not reused anymore for
subsequent frames after the changes in #31965. This works on MacOS for
hiding cursors, since they are hidden until the next mouse movement
occurs, which is not the case for other systems.
This PR re-adds this whilst keeping the fixes applied in #31965. We now
determine the first cursor style that is hovered and continue searching
for a cursor style that should be applied globally. If one to apply for
the whole window is found, we return that cursor style early instead.
Alternatively, we could store window cursor style request in a vector
similar to normal cursor styles. That would require more memory in
exchange for fewer checks which cursor style to apply. I preferred the
approach here, though, but can change this should the other method be
preferred.
CC @smitbarmase since you assigned yourself that issue.
Release Notes:
- Fixed an issue where the cursor would flicker whilst typing.
Follow-up to #24797
This PR ensures some cursor styles do not change for draggable elements
during dragging. The linked PR covered this on the higher level for
draggable divs. However, e.g. the pane divider inbetween two editors is
not a draggable div and thus still has the issue that the cursor style
changes during dragging. This PR fixes this issue by setting the hitbox
to `None` in cases where the element is currently being dragged, which
ensures the cursor style is applied to the cursor no matter what during
dragging.
Namely, this change fixes this for
- non-div pane dividers
- minimap slider and the
- editor scrollbars
and implements it for the UI scrollbars (Notably, UI scrollbars do
already have `cursor_default` on their parent container but would not
keep this during dragging. I opted out on removing this from the parent
containers until #30194 or a similar PR is merged).

pressing `j` will immediately show a `j`.
Allows setting element as window control elements which consist of

Fixes two things:
* ~3 months ago [in PR
#26420](https://github.com/zed-industries/zed/pull/26420/files#diff-33b58aa2da03d791c2c4761af6012851b7400e348922d64babe5fd48ac2a8e60)
`bindings_for_action` was changed to return bindings even when they are
shadowed (when the keystrokes would actually do something else).
* For edit prediction keybindings there was some odd behavior where
bindings for `edit_prediction_conflict` were taking precedence over
bindings for `edit_prediction` even when the `edit_prediction_conflict`
predicate didn't match. The workaround for this was #24812. The way it
worked was:
- List all bindings for the action
- For each binding, get the highest precedence binding with the same
input sequence
- If the highest precedence binding has the same action, include this
binding. This was the bug - this meant that if a binding in the keymap
has the same keystrokes and action it can incorrectly take display
precedence even if its context predicate does not pass.
- Fix is to check that the highest precedence binding is a full match.
To do this efficiently, it's based on an index within the keymap
bindings.
Also adds `highest_precedence_binding_*` variants which avoid the
inefficiency of building lists of bindings just to use the last.
Release Notes:
- Fixed display of keybindings to skip bindings that are shadowed by a
binding that uses the same keystrokes.
- Fixed display of `editor::AcceptEditPrediction` bindings to use the
normal precedence that prioritizes user bindings.
This PR implements the previously unimplemented window_handle and
display_handle methods in the wayland platform. It also exposes the
display_handle method through the Window struct.

tl;dr: This adds `.block_mouse_except_scroll()` which should typically
be used instead of `.occlude()` for cases when the mouse shouldn't
interact with elements drawn below an element. The rationale for
treating scroll events differently:
* Mouse move / click / styles / tooltips are for elements the user is
interacting with directly.
* Mouse scroll events are about finding the current outer scroll
container.
Most use of `occlude` should probably be switched to this, but I figured
I'd derisk this change by minimizing behavior changes to just the 3 uses
of `block_mouse_except_scroll`.
GPUI changes:
* Added `InteractiveElement::block_mouse_except_scroll()`, and removes
`stop_mouse_events_except_scroll()`
* Added `Hitbox::should_handle_scroll()` to be used when handling scroll
wheel events.
* `Window::insert_hitbox` now takes `HitboxBehavior` instead of
`occlude: bool`.
- `false` for that bool is now `HitboxBehavior::Normal`.
- `true` for that bool is now `HitboxBehavior::BlockMouse`.
- The new mode is `HitboxBehavior::BlockMouseExceptScroll`.
* Removes `Default` impl for `HitboxId` since applications should not
manually create `HitboxId(0)`.

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!(...));`
