Closes https://github.com/zed-industries/zed/issues/23505
Now `zed::IncreaseBufferFontSize` (and all the same UI- and
Buffer-related settings) action is parameterized with `{ "persist": true
}` (default).
Using `"persist": false` brings back resizing behavior prior to
https://github.com/zed-industries/zed/pull/23265
Release Notes:
- Added a way to toggle font size without settings adjustments
This PR formalizes design components with the Component and
ComponentPreview traits.
You can open the preview UI with `workspace: open component preview`.
Component previews no longer need to return `Self` allowing for more
complex previews, and previews of components like `ui::Tooltip` that
supplement other components rather than are rendered by default.
`cargo-machete` incorrectly identifies `linkme` as an unused dep on
crates that have components deriving `IntoComponent`, so you may need to
add this to that crate's `Cargo.toml`:
```toml
# cargo-machete doesn't understand that linkme is used in the component macro
[package.metadata.cargo-machete]
ignored = ["linkme"]
```

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
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure
- [x] Vim test failures
- [x] Mac build issue

Density tracking issue: #18078
This PR refactors our spacing system to use a more flexible and
maintainable approach. We've replaced the static `Spacing` enum with a
dynamically generated `DynamicSpacing` enum using a proc macro.
Enum variants now use a `BaseXX` format, where XX = the pixel value @
default rem size and the default UI density.
For example:
`CustomSpacing::Base16` would return 16px at the default UI scale &
density.
I'd love to find another name other than `Base` that is clear (to avoid
base_10, etc confusion), let me know if you have any ideas!
Changes:
- Introduced a new `derive_dynamic_spacing` proc macro to generate the
`DynamicSpacing` enum
- Updated all usages of `Spacing` to use the new `DynamicSpacing`
- Removed the `custom_spacing` function, mapping previous usages to
appropriate `DynamicSpacing` variants
- Improved documentation and type safety for spacing values
New usage example:
```rust
.child(
div()
.flex()
.flex_none()
.m(DynamicSpacing::Base04.px(cx))
.size(DynamicSpacing::Base16.rems(cx))
.children(icon),
)
```
vs old usage example:
```
.child(
div()
.flex()
.flex_none()
.m(Spacing::Small.px(cx))
.size(custom_spacing(px(16.)))
.children(icon),
)
```

This PR adds a theme preview tab to help get an at a glance overview of
the styles in a theme.

You can open it using `debug: open theme preview`.
The next major theme preview PR will move this into it's own crate, as
it will grow substantially as we add content.
Next for theme preview:
- Update layout to two columns, with controls on the right for selecting
theme, layer/elevation-index, etc.
- Cover more UI elements in preview
- Display theme colors in a more helpful way
- Add syntax & markdown previews
Release Notes:
- Added a way to preview the current theme's styles with the `debug:
open theme preview` command.
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.
Release Notes:
- N/A
Continuing from #13597, this PR refactors platform controls to extract a
generic set of platform controls that can be used for any platform that
does not define it's own/we don't use the system ones.
In the future, these controls will likely be used as a fallback on
windows as well when the windows icon font isn't available.
Release Notes:
- Added updated window controls on Linux
This PR replaces the rem size literals with the `BASE_REM_SIZE_IN_PX`
constant.
This way we can retain our source of truth for the rem size that we're
designing against.
Release Notes:
- N/A
Note: You shouldn't use the `unstable.ui_density` setting – it is only
being added for testing and to enable new UI components to be built with
density in mind. Don't expect this to work well, or at all right now.
Adds some of the basic wiring we'll need to start scaling UI elements
throughout the app based on a desired density setting.
Release Notes:
- N/A
- Centralizes typography-related UI styles and methods in
`styles/typography.rs`
- Breaks the typography-related styles out of `StyledExt`. This means we
add a `StyledTypography` trait – this should more or less be an
invisible change as we publish it in the prelude.
- adds the ability to easily grab the UI or Buffer font sizes
(`ui_font_size`, `buffer_font_size`) with `TextSize::UI`,
`TextSize::Editor`
Release Notes:
- N/A
This is a crate only addition of a new version of the AssistantPanel.
We'll be putting this behind a feature flag while we iron out the new
experience.

This adds so-called "inline git blame" to the editor that, when turned
on, shows `git blame` information about the current line inline:

When the inline information is hovered, a new tooltip appears that
contains more information on the current commit:

The commit message in this tooltip is rendered as Markdown, is
scrollable and clickable.
The tooltip is now also the tooltip used in the gutter:

## Settings
1. The inline git blame information can be turned on and off via
settings:
```json
{
"git": {
"inline_blame": {
"enabled": true
}
}
}
```
2. Optionally, a delay can be configured. When a delay is set, the
inline blame information will only show up `x milliseconds` after a
cursor movement:
```json
{
"git": {
"inline_blame": {
"enabled": true,
"delay_ms": 600
}
}
}
```
3. It can also be turned on/off for the current buffer with `editor:
toggle git blame inline`.
## To be done in follow-up PRs
- [ ] Add link to pull request in tooltip
- [ ] Add avatars of users if possible
## Release notes
Release Notes:
- Added inline `git blame` information the editor. It can be turned on
in the settings with `{"git": { "inline_blame": "on" } }` for every
buffer or, temporarily for the current buffer, with `editor: toggle git
blame inline`.
This PR updates the color of the label used for Git-aware items to use
the `ignored` color from the theme when the item is ignored by Git.
The built-in themes have had their `ignored` color updated to match
`text.disabled`, as the existing `ignored` color did not sufficiently
differentiate from non-ignored items.
Fixes#9976.
Release Notes:
- Updated items in the project panel to use the `ignored` color from the
theme when they are ignored by Git
([#9976](https://github.com/zed-industries/zed/issues/9976)).
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 PR adds a new `rems_from_px` helper function that can be used to
compute rem values based on a pixel value.
This is something we do fairly commonly, where we want to express a size
that is a given pixel size at the base rem size (e.g., "14px when the
rem size is 16px").
`rems_from_px` helps make the intent more explicit, as well as prevent
the base rem size from being duplicated everywhere.
Note: Ideally we would want `rems_from_px` to be `const`, but that
depends on https://github.com/rust-lang/rust/issues/57241.

### 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.
