### Problem
After transitioning Zed to GPUI 2, we started noticing that interacting
with the mouse on many UI elements would lead to a pretty annoying
flicker. The main issue with the old approach was that hover state was
calculated based on the previous frame. That is, when computing whether
a given element was hovered in the current frame, we would use
information about the same element in the previous frame.
However, inspecting the previous frame tells us very little about what
should be hovered in the current frame, as elements in the current frame
may have changed significantly.
### Solution
This pull request's main contribution is the introduction of a new
`after_layout` phase when redrawing the window. The key idea is that
we'll give every element a chance to register a hitbox (see
`ElementContext::insert_hitbox`) before painting anything. Then, during
the `paint` phase, elements can determine whether they're the topmost
and draw their hover state accordingly.
We are also removing the ability to give an arbitrary z-index to
elements. Instead, we will follow the much simpler painter's algorithm.
That is, an element that gets painted after will be drawn on top of an
element that got painted earlier. Elements can still escape their
current "stacking context" by using the new `ElementContext::defer_draw`
method (see `Overlay` for an example). Elements drawn using this method
will still be logically considered as being children of their original
parent (for keybinding, focus and cache invalidation purposes) but their
layout and paint passes will be deferred until the currently-drawn
element is done.
With these changes we also reworked geometry batching within the
`Scene`. The new approach uses an AABB tree to determine geometry
occlusion, which allows the GPU to render non-overlapping geometry in
parallel.
### Performance
Performance is slightly better than on `main` even though this new
approach is more correct and we're maintaining an extra data structure
(the AABB tree).

## Problem
We're trying to figure out why we sometimes see high latency when
collaborating, even though the collab server logs indicate that messages
are not taking long to process.
We think that high volumes of certain types of messages, including
`UpdateFollowers` may cause a lot of messages to queue up, causing
delays before collab sees certain messages.
## Fix
This PR reduces the number of `UpdateFollowers` messages that clients
send to collab when scrolling around or moving the cursor, using a
time-based throttle.
The downside of this change is that scrolling will not be as smooth when
following someone. The advantage is that it will be much easier to keep
up with the stream of updates, since they will be sent much less
frequently.
## Release Notes:
- Fixed slowness that could occur when collaborating due to excessive
messages being sent to support following.

This PR moves the Clippy configuration up to the workspace level.
We're using the [`lints`
table](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-lints-table)
to configure the Clippy ruleset in the workspace's `Cargo.toml`.
Each crate in the workspace now has the following in their own
`Cargo.toml` to inherit the lints from the workspace:
```toml
[lints]
workspace = true
```
This allows for configuring rust-analyzer to show Clippy lints in the
editor by using the following configuration in your Zed `settings.json`:
```json
{
"lsp": {
"rust-analyzer": {
"initialization_options": {
"check": {
"command": "clippy"
}
}
}
}
```
Release Notes:

This solves a major usability problem in Zed, that there's no way to
temporarily disable auto formatting without toggling the whole feature
off.
fixes https://github.com/zed-industries/zed/issues/5230
Release Notes:
- Added a new `workspace::SaveWithoutFormatting`, bound to `cmd-k s`, to
save a file without invoking the auto formatter.
Fixes: #8050
For some reason that we didn't investigate, if you have view caching
enabled,
and you have non-integer sized bounds, and you are right aligning
things, the
co-ordinates can differ by +/- 1px when using the cached view.
The easiest fix for now is to just not do that.

Release Notes:
- Fixed the pane icons flickering
([#8050](https://github.com/zed-industries/zed/issues/8050)).

I would like to keep diagnostics open on one side, and process them on
the other.
Release Notes:
- Added `editor::OpenExcerptsSplit` (bound to `cmd-k enter`) to open the
selected excerpts in the adjacent pane
- vim: Added `ctrl-w d`, `ctrl-w shift-d` and `ctrl-w space` for
`editor::GoTo{,Type}Definition` and `editor::OpenExcerptsSplit`
This reverts commit 0cebf68306.
Although this thing is very cool, it is a top source of crashes.
Example crash:
```
Segmentation fault: 11 on thread 26
objc_retain +16
invocation function for block in Overlay::onCommandBufferCommit(id<MTLCommandBuffer>) +60
MTLDispatchListApply +52
```
Release Notes:
- Removed "Toggle Graphics Profiler" as it crashes too much.
This uses bounds checking alone to determine hover state to avoid
flicker. It's a short-term solution because the rendering is incorrect.
We think this is better than flickering though and buys us some time as
we work on a more robust solution overall.
Release Notes:
- Fixed flickering when hovering.

Release Notes:
- Added
[`:tabo[nly][!]`](https://neovim.io/doc/user/tabpage.html#%3Atabonly),
closes all the tabs except the active one but in the current pane only,
every other split pane remains unaffected.
The version with the `!` force closes the tabs while the one without
asks you to save or discard the changes.
- Added [`:on[ly][!]`](https://neovim.io/doc/user/windows.html#%3Aonly),
closes all the tabs *and* panes except the active one.
The version with the `!` force closes the tabs while the one without
asks you to save or discard the changes.
Since Zed does not have different splits per tab like in Neovim `:only`
works the same as it does in VscodeVim.

Add plumbing for hosted projects. This will currently show them if they
exist
but provides no UX to create/rename/delete them.
Also changed the `ChannelId` type to not auto-cast to u64; this avoids
type
confusion if you have multiple id types.
Release Notes:
- N/A

Fixes https://github.com/zed-industries/zed/issues/7419 by changing the
way "recent projects" modal confirm actions work:
* `menu::Confirm` now reuses the current window when opening a recent
project
* `menu::SecondaryConfirm` now opens a recent project in the new window
* neither confirm tries to open the current project anymore
* modal's placeholder is adjusted to emphasize this behavior
Release Notes:
- Added a way to open recent projects in the new window
This PR adds a `SystemClock` trait for abstracting away the system
clock.
This allows us to swap out the real system clock with a
`FakeSystemClock` in the tests, thus allowing the fake passage of time.
We're using this in `Telemetry` to better mock the clock for testing
purposes.
Release Notes:
- N/A
Release Notes:
- Added `workspace::SendKeystrokes` to enable mapping from one key to a
sequence of others
([#7033](https://github.com/zed-industries/zed/issues/7033)).
Improves #7033. Big thank you to @ConradIrwin who did most of the heavy
lifting on this one.
This PR allows the user to send multiple keystrokes via custom
keybinding. For example, the following keybinding would go down four
lines and then right four characters.
```json
[
{
"context": "Editor && VimControl && !VimWaiting && !menu",
"bindings": {
"g z": [
"workspace::SendKeystrokes",
"j j j j l l l l"
],
}
}
]
```

Part of #7108
This PR includes just the static runnables part. We went with **not**
having a dedicated panel for runnables.
This is just a 1st PR out of N, as we want to start exploring the
dynamic runnables front. Still, all that work is going to happen once
this gets merged.
Release Notes:
- Added initial, static Runnables support to Zed. Such runnables are defined in
`runnables.json` file (accessible via `zed: open runnables` action) and
they can be spawned with `runnables: spawn` action.

This could cause following to get into a bad state temporarily
Release Notes:
- Fixed a bug around following if the follow started while the workspace
was inactive.
