The new `ElementContext` was originally introduced to ensure the element
APIs could only be used inside of elements. Unfortunately, there were
many places where some of those APIs needed to be used, so
`WindowContext::with_element_context` was introduced, which defeated the
original safety purposes of having a specific context for elements.
This pull request merges `ElementContext` into `WindowContext` and adds
(debug) runtime checks to APIs that can only be used during certain
phases of element drawing.

This pull request introduces the new
`ElementContext::request_autoscroll(bounds)` and
`ElementContext::take_autoscroll()` methods in GPUI. These new APIs
enable container elements such as `List` to change their scroll position
if one of their children requested an autoscroll. We plan to use this in
the revamped assistant.
As a drive-by, we also:
- Renamed `Element::before_layout` to `Element::request_layout`
- Renamed `Element::after_layout` to `Element::prepaint`
- Introduced a new `List::splice_focusable` method to splice focusable
elements into the list, which enables rendering offscreen elements that
are focused.

This PR includes two relevant changes:
- Platform binds (super, windows, cmd) will now parse on all platforms,
regardless of which one is being used. While very counter-intuitive
(this means that `cmd-d` will actually be triggered by `win-d` on
windows) this makes it possible to reuse keymap files across platforms
easily
- There is now a KeyContext `os == linux`, `os == macos` or `os ==
windows` available in keymaps. This allows users to specify certain
blocks of keybinds only for one OS, allowing you to minimize the amount
of keymappings that you have to re-configure for each platform.
Release Notes:
- Added `os` KeyContext, set to either `linux`, `macos` or `windows`
- Fixed keymap parsing errors when `cmd` was used on linux, `super` was
used on mac, etc.

Fixes
https://github.com/zed-industries/zed/pull/9754#issuecomment-2060536590
Closes https://github.com/zed-industries/zed/pull/10669
* Updates the docs to use a proper max value for the centered layout
padding (0.4 instead of 0.45)
* Makes the `center` wrapper (`h_flex`) to be of size of the `center`
element always, to ensure terminal lines are displayed correctly
The letter fix is somewhat hacky: while it does the right thing right
now, it does not prevent us from future mistakes like these, and does
not explain why the bottom dock could be of one, smaller, height, and
its contents, the terminal pane/terminal element/something else would
think that it has a larger height, thus breaking the scrolling and
rendering.
cc @alygin if you're interested to solve another layout-related thing.
Release Notes:
- N/A
This PR implements the Centered Layout feature (#4685):
- Added the `toggle centered layout` action.
- The centered layout mode only takes effect when there's a single
central pane.
- The state of the centered layout toggle is saved / restored between
Zed restarts.
- The paddings are controlled by the `centered_layout` setting:
```json
"centered_layout": {
"left_padding": 0.2,
"right_padding": 0.2
}
```
This allows us to support both the VSCode-style (equal paddings) and
IntelliJ-style (only left padding in Zen mode).
Release Notes:
- Added support for Centered Layout
([#4685](https://github.com/zed-industries/zed/pull/9754)).

This PR implements the preview tabs feature from VSCode.
More details and thanks for the head start of the implementation here
#6782.
Here is what I have observed from using the vscode implementation ([x]
-> already implemented):
- [x] Single click on project file opens tab as preview
- [x] Double click on item in project panel opens tab as permanent
- [x] Double click on the tab makes it permanent
- [x] Navigating away from the tab makes the tab permanent and the new
tab is shown as preview (e.g. GoToReference)
- [x] Existing preview tab is reused when opening a new tab
- [x] Dragging tab to the same/another panel makes the tab permanent
- [x] Opening a tab from the file finder makes the tab permanent
- [x] Editing a preview tab will make the tab permanent
- [x] Using the space key in the project panel opens the tab as preview
- [x] Handle navigation history correctly (restore a preview tab as
preview as well)
- [x] Restore preview tabs after restarting
- [x] Support opening files from file finder in preview mode (vscode:
"Enable Preview From Quick Open")
I need to do some more testing of the vscode implementation, there might
be other behaviors/workflows which im not aware of that open an item as
preview/make them permanent.

Fixes#7694
The new setting accepts "last_workspace" (default) and "none" as
options.
In a follow-up PR I'll add a new option that re-launches all of the Zed
windows and not just the last one.
Release Notes:
- Added `restore_on_startup` option, accepting `last_workspace`
(default) and `none` options. With `none`, new Zed instances will not
restore workspaces that were open last.
This PR reworks the way workspace notifications are identified to use a
new `NotificationId` type.
A `NotificationId` is bound to a given type that is used as a unique
identifier. Generally this will be a unit struct that can be used to
uniquely identify this notification.
A `NotificationId` can also accept an optional `ElementId` in order to
distinguish between different notifications of the same type.
This system avoids the issue we had previously of selecting `usize` IDs
somewhat arbitrarily and running the risk of having two independent
notifications collide (and thus interfere with each other).
This also fixes a bug where multiple suggestion notifications for the
same extension could be live at once

This PR contains various improvements for the markdown preview (some of
which were originally part of #7601).
Some improvements can be seen in the video (see also release notes down
below):
https://github.com/zed-industries/zed/assets/53836821/93324ee8-d366-464a-9728-981eddbfdaf7
Release Notes:
- Added action to open markdown preview in the same pane
- Added support for displaying channel notes in markdown preview
- Added support for displaying the current active editor when opening
markdown preview
- Added support for scrolling the editor to the corresponding block when
double clicking an element in markdown preview
- Improved pane creation handling when opening markdown preview
- Fixed markdown preview displaying non-markdown files
Due to peculiarities in handling of terminal panes (namely the fact that
they are not actually tracked by the Workspace::active_pane member), it
was possible to get into a state where status bar items "lost track" of
an active pane item; one way to reproduce it was to open a new terminal
via "workspace: new terminal" with a pane open in a central view; once a
new terminal is opened, the language selector and line number indicator
lose track of an active item. Focusing central view does nothing - it
will only go away after switching a tab in the central view.
To remedy this, we now always notify the status bar items of a pane
focus change, even if Workspace::active_pane points to the same pane.
Release Notes:
- Fixed status bar focus issues when spawning a terminal via `workspace:
new terminal` action.
1. They now will not go off-screen
2. You can scroll long messages.
3. Only one notification per language server is shown at a time
4. The title/text are now distinguished visually
5. You can copy the error message to the clipboard
Fixes: #10217Fixes: #10190Fixes: #10090
Release Notes:
- Fixed language server notifications being too large
([#10090](https://github.com/zed-industries/zed/issues/10090)).
@SomeoneToIgnore This code should 100% work for future Zed users, but
for current Zed users, Zed's internal list of recents may not be synced
w/ macOS' Recent Documents at first. If needed this can be fixed by
calling `cx.refresh_recent_documents` on startup, but that feels a bit
unnecessary.
Release Notes:
- Fixes behavior of Recent Documents list on macOS
Introducing the Active File Context portion of #9705. When someone is in
the assistant panel it now includes the active file as a system message
on send while showing them a nice little display in the lower right:

For this iteration, I'd love to see the following before we land this:
* [x] Toggle-able context - user should be able to disable sending this
context
* [x] Show nothing if there is no context coming in
* [x] Update token count as we change items
* [x] Listen for a more finely scoped event for when the active item
changes
* [x] Create a global for pulling a file icon based on a path. Zed's
main way to do this is nested within project panel's `FileAssociation`s.
* [x] Get the code fence name for a Language for the system prompt
* [x] Update the token count when the buffer content changes
I'm seeing this PR as the foundation for providing other kinds of
context -- diagnostic summaries, failing tests, additional files, etc.
Release Notes:
- Added file context to assistant chat panel
([#9705](https://github.com/zed-industries/zed/issues/9705)).

Sharing a project displays a notification (window) on every screen.
Previously there was an issue with the positioning of windows on all
screens except the primary screen.
As you can see here:

Now:

@mikayla-maki and I also decided to refactor the `WindowOptions` a bit.
Previously you could specify bounds which controlled the positioning and
size of the window in the global coordinate space, while also providing
a display id (which screen to show the window on). This can lead to
unusual behavior because you could theoretically specify a global bound
which does not even belong to the display id which was provided.
Therefore we changed the api to this:
```rust
struct WindowOptions {
/// The bounds of the window in screen coordinates
/// None -> inherit, Some(bounds) -> set bounds.
pub bounds: Option<Bounds<DevicePixels>>,
/// The display to create the window on, if this is None,
/// the window will be created on the main display
pub display_id: Option<DisplayId>,
}
```
This lets you specify a display id, which maps to the screen where the
window should be created and bounds relative to the upper left of the
screen.
Release Notes:
- Fixed positioning of popup windows (e.g. when sharing a project) when
using multiple external displays.

This pull request introduces a new `InlineCompletionProvider` trait,
which enables making `Editor` copilot-agnostic and lets us push all the
copilot functionality into the `copilot_ui` module. Long-term, I would
like to merge `copilot` and `copilot_ui`, but right now `project`
depends on `copilot`, which makes this impossible.
The reason for adding this new trait is so that we can experiment with
other inline completion providers and swap them at runtime using config
settings.
Please, note also that we renamed some of the existing copilot actions
to be more agnostic (see release notes below). We still kept the old
actions bound for backwards-compatibility, but we should probably remove
them at some later version.
Also, as a drive-by, we added new methods to the `Global` trait that let
you read or mutate a global directly, e.g.:
```rs
MyGlobal::update(cx, |global, cx| {
});
```
Release Notes:
- Renamed the `copilot::Suggest` action to
`editor::ShowInlineCompletion`
- Renamed the `copilot::NextSuggestion` action to
`editor::NextInlineCompletion`
- Renamed the `copilot::PreviousSuggestion` action to
`editor::PreviousInlineCompletion`
- Renamed the `editor::AcceptPartialCopilotSuggestion` action to
`editor::AcceptPartialInlineCompletion`

make new runs of zed always match the window of the previous run of Zed,
even if it's not the same workspace
fixes https://github.com/zed-industries/zed/issues/5258
Release Notes:
- Zed will always open new windows with the same position and location
as the previous instance of Zed.
This PR continues the refinements to the `TitleBar` component.
Here are the notable changes:
- `KeyBindingDisplay` and `PlatformStyle` have been unified into a
single `PlatformStyle`.
- This provides us a consistent way for adapting UI to different
platform styles.
- `PlatformTitlebar` has been renamed to `TitleBar`.
- The `Platform` prefix was irrelevant.
- The Windows window controls have been factored out into a separate
module and have been componentized.

This reverts #9053 and #9375 because they introduced a regression on
`main` that broke the titlebars on macOS:

Two things are off:
- Left padding is missing
- Titlebar height is less than it was before, which means the
traffic-light buttons are not centered vertically
What @as-cii and I noticed while looking into this: the `cfg!(macos)`
macros that were used don't work like that. You need to check for
`cfg!(target = "macos")` etc. Means that on macOS we never used the
macOS-specific code because the condition was always false.
Overall height, we're not sure about.
Release Notes:

This is the beginning of setting up a flexible way to open items beyond
the text buffer -- think notebooks, images, GeoJSON, etc. The primary
requirement to allow opening an arbitrary file is `try_open` on the
`project::Item` trait. Now we can make new `Item`s for other types with
their own ways to render.
Under the hood, `register_project_item` uses this new opening scheme. It
supports a dynamic array of opener functions, that will handle specific
item types. By default, a `Buffer` should be able to be able to open any
file that another opener did not.
A key detail here is that the order of registration matters. The last
item has primacy. Here's an example:
```rust
workspace::register_project_item::<Editor>(cx);
workspace::register_project_item::<Notebook>(cx);
workspace::register_project_item::<ImageViewer>(cx);
```
When a project item (file) is attempted to be opened, it's first tried
with the `ImageViewer`, followed by the `Notebook`, then the `Editor`.
The tests are set up in a way that should make it _hopefully_ easy to
learn how to write a new opener. First to go after should probably be
image files.

Closes#5178
Release Notes:
- Added a `file_types` setting that can be used to associate languages
with file names and file extensions. For example, to interpret all `.c`
files as C++, and files called `MyLockFile` as TOML, add the following
to `settings.json`:
```json
{
"file_types": {
"C++": ["c"],
"TOML": ["MyLockFile"]
}
}
```
As with most zed settings, this can be configured on a per-directory
basis by including a local `.zed/settings.json` file in that directory.

Before this change we didn't consistently trigger focus events when
toggling between with windows `Cmd-backtick`. We only triggered them
when the OS decided to trigger a redraw.
That lead to a nasty bug that showed up in Vim mode where a cursor would
still be active in the hidden window, even though it was deactivated.
One then had to manually try to trigger a focus event in the new window
to activate the cursor.
With this change, we call `cx.refresh` when the window activation status
changed which triggers focus events consistently and fixes this bug.
With logging we can observe this:

When neither is specified, if you open a directory you get a new

With --new files are always opened in a new workspace
With --add directories are always added to an existing workspace
Fixes#9076Fixes#4861Fixes#5370
Release Notes:
- Added `-n/--new` and `-a/--add` to the zed CLI. When neither is
specified, if you open a directory you get a new workspace, otherwise
files are added to your existing workspace. With `--new` files are
always opened in a new workspace, with `--add` directories are always

[#4861](https://github.com/zed-industries/zed/issues/4861),
[#5370](https://github.com/zed-industries/zed/issues/5370)).
This fixes#8072 and #9061 by surfacing formatting errors in the
activity indicator.
It shows a message in the activity indicator if the last attempt
to format a buffer failed.
It only keeps track of the last attempt, so any further formatting
that succeeds will reset or update the error message.
I chose to only keep track of that, because everything else (keeping
track of formatting state per buffer, per project, per worktree) seems
complicated with little benefit, since we'd have to keep track of that
state, update it, clean it, etc.
We can still do that should we decide that we need to keep track
of the state on a per-buffer basis, but I think for now this is a
good, simple solution.
This also changes the `OpenLog` action to scroll to the end of the
buffer
and to not mark the buffer as dirty.
Release Notes:
- Added message to activity indicator if last attempt to format a buffer
failed. Message will get reset when next formatting succeeds. Clicking
on message opens log with more information.
([#8072](https://github.com/zed-industries/zed/issues/8072) and

- Changed `zed: Open Log` action to not mark the opened log file as
dirty and to always scroll to the bottom of the log.

### 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).

Release Notes:
- Fixed a bug that was causing popovers to flicker.

## 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.
