This PR fixes several possible memory leaks due to loading images in
markdown files and the image viewer, using the new image cache APIs
TODO:
- [x] Ensure this didn't break rendering in any of the affected
components.
Release Notes:
- Fixed several image related memory leaks
cc: @sunli829 @huacnlee @probably-neb
I really liked the earlier PR, but had an idea for how to utilize the
element state so that you don't need to construct the cache externally.
I've updated the APIs to introduce an `ImageCacheProvider` trait, and
added an example implementation of it to the image gallery :)
Release Notes:
- N/A
Closes#27414
`ImageCache` is independent of the original image loader and can
actively release its cached images to solve the problem of images loaded
from the network or files not being released.
It has two constructors:
- `ImageCache::new`: Manually manage the cache.
- `ImageCache::max_items`: Remove the least recently used items when the
cache reaches the specified number.
When creating an `img` element, you can specify the cache object with
`Img::cache`, and the image cache will be managed by `ImageCache`.
In the example `crates\gpui\examples\image-gallery.rs`, the
`ImageCache::clear` method is actively called when switching a set of
images, and the memory will no longer continuously increase.

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:
- N/A
Earlier, I merged #24723
Before merging it, I made a change that was incorrect and fast followed
with a fix: #28548
Following that fix, @bennetbo discovered that the modals where no longer
highlighting correctly, particularly the outline modal.
So I'm going to revert it all.

Fix this long-standing issue so that we can support Link hover colors.
And renamed `text_layout` example to `text_style`.
---
I spent some time studying the process of this text style change and
found it a bit complicated.
At first, I thought there was a problem with refine and it was not
passed properly. After changing it, I found that it was not the problem.
Then I found that it was because `TextRun` had already stored the
`color`, `background`, `underline`, `strikethrough` in TextRun in the
`request_layout` stage. They area calculate at the `request_layout`
stage, but request_layout stage there was no `hitbox`, so the hover
state was not obtained.
```bash
cargo run -p gpui --example text_style
```

Closes#4461
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.

I will try to do some test.
For example: With a threshold for the hold number of caches in
`FrameCache`, and only when the threshold is greater than a certain

This example is added to help us to test.

- [x] PatternDash
- [x] `pattern_horizontal_dash` & `pattern_vertical_dash`
- [x] Metal dash shader
- [x] Blade dash shader
- [x] Update ui::Divider to use new pattern
---
This PR introduces proper dashed dividers using the new `PatternDash`
background shader.

Before this we were using 128 elements to create a dashed divider, which
is both expensive, and would not scale beyond a certain size. This
allows us to simplify the divider element as well.
Changes:
- Adds `BackgroundOrientation` to `gpui::color::Background` to allow
specifying a direction for a pattern
- Adds the PatternDash pattern variant
- Updates `ui::Divider`'s dashed variants to be more efficient
Misc:
- Documents the `ui::Divider` component
- Treat `.metal` files as `C` in the Zed project until we get some metal
syntax highlighting.
Release Notes:
- N/A
TODO:
- [x] Add BackgroundTag::PatternSlash
- [x] Support metal slash pattern fills
- [x] Support blade slash pattern fills
---
Adds support for a new background type in gpui, `pattern_slash`.
Usage:
```rust
div().size(px(56.0)).bg(pattern_slash(gpui::red()))
```
This will create a 56px square with a red slash pattern fill.
You can run the pattern example with `cargo run -p gpui --example
pattern`:

---
After talking with @as-cii at length about how we want to support
patterns in gpui, we decided for now we'll simply add a new
BackgroundTag specific to this pattern.
It isn't the best long term plan however – we'll likely want to
introduce the concept of a `Fill` at some point so we can have
`Fill::Solid`, `Fill::Gradient(LinearGradient)`, etc in the future.
The pattern is designed to seamlessly tile vertically for elements of
the same height. For example, for use in editor line backgrounds:

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:
- N/A
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

the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`

When launching the Pinyin keyboard, macOS will sometimes try to peek one
character back in the string.
This caused a panic if the preceding character was an emoji. The docs
say
"don't assume the range is valid", so now we don't.
Release Notes:
- (macOS) Fixed a panic when using the Pinyin keyboard with emojis
As part of the recent changes to keyboard support, ime_key is no longer
populated by the IME; but instead by the keyboard.
As part of #20877 I changed some code to assume that falling back to key
was
ok, but this was not ok; instead we need to populate this more similarly
to how
it was done before #20336.
The alternative fix could be to instead of simulating these events in
our own
code to push a fake native event back to the platform input handler.

- Fixed a bug where tapping `shift` coudl type "shift" if you had a

I added this demo to verify the detailed support of Path drawing in
GPUI.
Because of, when we actually used GPUI to draw a 2D line chart, we found
that the straight line Path#line_to did not support `anti-aliasing`, and
the drawn line looked very bad.
As shown in the demo image, if we zoom in on the image, we can clearly
see that all the lines are jagged.
I read and tried to make some appropriate adjustments to the functions
in Path, but since I have no experience in the graphics field, I still
cannot achieve anti-aliasing support so far.
I don't know if I used it wrong somewhere. I checked `curve_to` and
found that the curves drawn have anti-aliasing effects, as shown in the
arc part of the figure below.

@iamnbutler edit:
This pull request enhances the image element by introducing the ability
to display loading and fallback states.
Changes:
- Implemented the loading and fallback states for image elements using
`.with_loading` and `.with_fallback` respectively.
- Introduced the `StyledImage` trait and `ImageStyle` to enable a fluent
API for changing image styles across image types (`Img`,
`Stateful<Img>`, etc).
Example Usage:
```rust
fn loading_element() -> impl IntoElement {
div().size_full().flex_none().p_0p5().rounded_sm().child(
div().size_full().with_animation(
"loading-bg",
Animation::new(Duration::from_secs(3))
.repeat()
.with_easing(pulsating_between(0.04, 0.24)),
move |this, delta| this.bg(black().opacity(delta)),
),
)
}
fn fallback_element() -> impl IntoElement {
let fallback_color: Hsla = black().opacity(0.5);
div().size_full().flex_none().p_0p5().child(
div()
.size_full()
.flex()
.items_center()
.justify_center()
.rounded_sm()
.text_sm()
.text_color(fallback_color)
.border_1()
.border_color(fallback_color)
.child("?"),
)
}
impl Render for ImageLoadingExample {
fn render(&mut self, _cx: &mut ViewContext<Self>) -> impl IntoElement {
img("some/image/path")
.id("image-1")
.with_fallback(|| Self::fallback_element().into_any_element())
.with_loading(|| Self::loading_element().into_any_element())
}
}
```
Note:
An `Img` must have an `id` to be able to add a loading state.

Re-land of #20515 with less brokenness
In particular it turns out that for control, the .characters() method
returns the control code. This mostly didn't make a difference, except
when the control code matched tab/enter/escape (for
ctrl-y,ctrl-[/ctrl-c) as we interpreted the key incorrectly.
Secondly, we were setting IME key too aggressively. This led to (in vim
mode) cmd-shift-{ being interpreted as [, so vim would wait for a second
[ before letting you change tab.
Release Notes:
- N/A
This reverts commit https://github.com/zed-industries/zed/pull/20515
I'm reverting for now to fix issues with key bindings on Nightly:
* `ctrl-c` and `ctrl-m` are being treated as `ctrl-enter`
* `ctrl-[` isn't working in vim mode
* there's a delay before `cmd-shift-[` switches tabs w/ vim mode enabled
Release Notes:
- N/A
