Fix a bug where a GPUI macro still used `ModelContext`
Rename `AsyncAppContext` -> `AsyncApp`
Rename update_model, read_model, insert_model, and reserve_model to
update_entity, read_entity, insert_entity, and reserve_entity
Release Notes:

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

* Collects and reports all parse errors
* Shares parsed `KeyBindingContextPredicate` among the actions.
* Updates gpui keybinding and action parsing to return structured
errors.
* Renames "block" to "section" to match the docs, as types like
`KeymapSection` are shown in `json-language-server` hovers.
* Removes wrapping of `context` and `use_key_equivalents` fields so that
`json-language-server` auto-inserts `""` and `false` instead of `null`.
* Updates `add_to_cx` to take `&self`, so that the user keymap doesn't
get unnecessarily cloned.
In retrospect I wish I'd just switched to using TreeSitter to do the
parsing and provide proper diagnostics. This is tracked in #23333
Release Notes:
- Improved handling of errors within the user keymap file. Parse errors
within context, keystrokes, or actions no longer prevent loading the key
bindings that do parse.

- Adds the Switch component
- Updates `Selected`, `Selectable` -> `ToggleState`, `Toggleable`
- Adds `checkbox` and `switch` functions to align better with other
elements in our layout system.
We decided not to merge Switch and Checkbox. However, in a followup I'll
introduce a Toggle or AnyToggle enum so we can update
`CheckboxWithLabel` -> `ToggleWithLabel` as this component will work
exactly the same with either a Checkbox or a Switch.

This PR reverts #20076 to turn the `ThemeRegistry` back into a regular
struct again.
It doesn't actually help us by having it behind a trait.
Release Notes:
- N/A
This PR converts the `ThemeRegistry` type into a trait instead of a
concrete implementation.
This allows for the extension store to depend on an abstraction rather
than the concrete theme registry implementation.
We currently have two `ThemeRegistry` implementations:
- `RealThemeRegistry` — this was previously the `ThemeRegistry` and
contains the real implementation of the registry.
- `VoidThemeRegistry` — a null object that doesn't have any behavior.

Similar to https://github.com/zed-industries/zed/pull/18690 &
https://github.com/zed-industries/zed/pull/18695, this PR enables
required docs for `ui` and does some cleanup.
Changes:
- Enables the `deny(missing_docs)` crate-wide.
- Adds `allow(missing_docs)` on many modules until folks pick them up to
document them
- Documents some modules (all in `ui/src/styles`)
- Crate root-level organization: Traits move to `traits`, other misc
organization
- Cleaned out a bunch of unused code.
Note: I'd like to remove `utils/format_distance` but the assistant panel
uses it. To move it over to use the `time_format` crate we may need to
update it to use `time` instead of `chrono`. Needs more investigation.

Reverts #13857. Hiding tooltips for selected buttons prevents tooltips
like "Close x dock" from showing up, see #14938 for an example.
The intention of the original PR was to hide the "Show application menu"
tooltip, while the context menu is open.
In order to fix this without breaking other UI elements, we track the
state of the context menu using `PopoverMenuHandle` now, which allows us
to prevent the tooltip from showing up while the context menu is open.
Closes#14938
Release Notes:
- Fixed an issue where some tooltips would not show up
This PR pulls non-icon assets out of `ui::components::icon` in
preparation for icon standardization.
In the future icons will have standard names and sizes, and these image
assets won't conform to those constraints.
We can also add a `ui::components::image::Image` wrapper around the
`gpui::img` element in the future for any Zed-specific image styling we
want to enforce.
Of note:
```rust
#[derive(Debug, PartialEq, Eq, Copy, Clone, EnumIter, EnumString, IntoStaticStr, Serialize, Deserialize, DerivePathStr)]
#[strum(serialize_all = "snake_case")]
#[path_str(prefix = "images", suffix = ".svg")]
pub enum VectorName {
ZedLogo,
ZedXCopilot,
}
```
You can see in the above code we no longer need to manually specify
paths for image/icon enums like we currently do in
`ui::components::icon`.
The icon component will get this same treatment in the future, once we:
- do the design work needed to standardize the icons
- remove unused icons
- update icon names
Release Notes:
- N/A
This PR adds an initial set of default colors to `gpui`.
These will power default-styled gpui components (things like checkboxes,
buttons, inputs, etc.), storybook, and give a very simple,
appearance-aware set of colors out of the box for folks to build with.
These colors will evolve and be updated in the near future, they are
literally pulled from Finder for now :)
The API might not be perfect, I focused on getting something in quickly
that we can iterate on!
### Usage
```rs
use gpui::{colors, DefaultColor}
fn auto(cx: &WindowContext) -> {
// Init the full set of DefaultColors
let colors = colors(cx.appearance());
// Use a color
// It will automatically give you the correct color for the system's
// current appearance.
let background = DefaultColor::Background.hsla(&colors)
}
fn manual() -> {
// Init the full sets of DefaultColors
let light_colors = DefaultColors::light();
let dark_colors = DefaultColors::dark();
// Use a color
// Maybe for some fancy inverted element
let background = DefaultColor::Background.hsla(&light_colors)
let inverted_background = DefaultColor::Background.hsla(&dark_colors)
let inverted_text = DefaultColor::Text.hsla(&dark_colors)
}
```
Note: We need `cx` for the auto way as we need to get the system
appearance from the App/Window/ViewContext via `cx.appearance()`.
### Example
You can run `script/storybook default_colors` to open the Default Colors
story:
| Light | Dark |
|-------|------|
| 
|

This PR removes the wiring for `assistant2` that hooks it up to Zed.
Since we're focusing in on improving the current assistant, we don't
need this present in Zed.
I left the `assistant2` crate intact for now, to make it easier to
reference any code from it.

This PR adds a new `WithRemSize` element to the `ui` crate.
This element can be used to create an element tree that has a different
rem size than the base window.
`WithRemSize` can be nested, allowing for subtrees that have a different
rem size than their parent and their children.

Now, regardless of how the Zed window is closed, Zed can remember the
window's restore size.
- [x] Windows implementation
- [x] macOS implementation
- [x] Linux implementation (partial)
- [x] update SQL data base (mark column `fullscreen` as deprecated)
The current implementation on Linux is basic, and I'm not sure if it's
correct.
The variable `fullscreen` in SQL can be removed, but I'm unsure how to
do it.
edit: mark `fullscreen` as deprecated
### Case 1
When the window is closed as maximized, reopening it will open in the
maximized state, and returning from maximized state will restore the
position and size it had when it was maximized.
https://github.com/zed-industries/zed/assets/14981363/7207752e-878a-4d43-93a7-41ad1fdb3a06
### Case 2
When the window is closed as fullscreen, reopening it will open in
fullscreen mode, and toggling fullscreen will restore the position and
size it had when it entered fullscreen (note that the fullscreen
application was not recorded in the video, showing a black screen, but
it had actually entered fullscreen mode).
https://github.com/zed-industries/zed/assets/14981363/ea5aa70d-b296-462a-afb3-4c3372883ea3
### What's more
- As English is not my native language, some variable and struct names
may need to be modified to match their actual meaning.
- I am not familiar with the APIs related to macOS and Linux, so
implementation for these two platforms has not been done for now.
- Any suggestions and ideas are welcome.

This PR sets up the `assistant2` crate with the storybook so that UI

Earlier versions where a simple find-replace of `cmd` => `ctrl`. In this
PR, I've gone over every keybinding individually and checked them.
Release Notes:
- Removed the `ShowContextMenu` action, it's only usage was in the
collab panel and it's been rebound to `SecondaryConfirm`
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 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.

### 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.
