Tracking Issue (does not close):
https://github.com/zed-industries/zed/issues/35552
This is somewhat of a blocker for
https://github.com/zed-industries/zed/pull/40035 (but also the current
behavior doesn't really make sense).
The current behavior of `ThemeSelectorDelegate::set_theme` (the theme
selector menu) is to simply set the in-memory settings to `Static`,
regardless of if it is currently `Dynamic`. The reason this doesn't
matter now is that the `theme::set_theme` function that updates the
user's settings file _will_ make this check, so dynamic settings stay
dynamic in `settings.json`, but not in memory.
But this is also sort of strange, because `theme::set_theme` will set
the setting of whatever the old appearance was to the new theme name. In
other words, if I am currently on a light mode theme and I change my
theme to a dark mode theme using the theme selector, the `light` field
of `theme` in `settings.json` is set to a dark mode theme!
_I think this is because displaying the new theme in the theme selector
does not update the global context, so
`ThemeSettings::get_global(cx).theme.name(appearance).0` returns the
original theme appearance, not the new one._
---
This PR makes `ThemeSelectorDelegate::set_theme` keep the current
`ThemeSelection`, as well as changes the behavior of the
`theme::set_theme` call to always choose the correct setting to update.
One edge case that might be slightly strange now is that if the user has
specified the mode as `System`, this will now override that with the
appearance of the new theme. I think this is fine, as otherwise a user
might set a dark theme and nothing will change because the
`ThemeAppearanceMode` is set to `light` or `system` (where `system` is
also light).
I also have an `unreachable!` in there that I'm pretty sure is true but
I don't really know how to formally prove that...

This PR adds word/character diff for expanded diff hunks that have both
a deleted and added section, as well as a setting `word_diff_enabled` to
enable/disable word diffs per language.
- `word_diff_enabled`: Defaults to true. Whether or not expanded diff
hunks will show word diff highlights when they're able to.
### Preview

/>
### Architecture
I had three architecture goals I wanted to have when adding word diff
support:
- Caching: We should only calculate word diffs once and save the result.
This is because calculating word diffs can be expensive, and Zed should
always be responsive.
- Don't block the main thread: Word diffs should be computed in the
background to prevent hanging Zed.
- Lazy calculation: We should calculate word diffs for buffers that are
not visible to a user.
To accomplish the three goals, word diffs are computed as a part of
`BufferDiff` diff hunk processing because it happens on a background
thread, is cached until the file is edited, and is only refreshed for
open buffers.
My original implementation calculated word diffs every frame in the
Editor element. This had the benefit of lazy evaluation because it only
calculated visible frames, but it didn't have caching for the
calculations, and the code wasn't organized. Because the hunk
calculations would happen in two separate places instead of just
`BufferDiff`. Finally, it always happened on the main thread because it
was during the `EditorElement` layout phase.
I used Zed's
[`diff_internal`](02b2aa6c50/crates/language/src/text_diff.rs (L230-L267))
as a starting place for word diff calculations because it uses
`Imara_diff` behind the scenes and already has language-specific
support.
#### Future Improvements
In the future, we could add `AST` based word diff highlights, e.g.
https://github.com/zed-industries/zed/pull/43691.
Release Notes:
- git: Show word diff highlight in expanded diff hunks with less than 5
lines.
- git: Add `word_diff_enabled` as a language setting that defaults to
true.

There was a TODO in `crates/settings/src/settings_content/theme.rs` to
make this rename.
This PR is just splitting off this change from

one a bit easier since that PR is a bit more involved than expected.

Follow-up: https://github.com/zed-industries/zed/pull/34655
We should use an opaque fallback color for `panel.overlay_hover`. This
helps when a custom theme doesn’t provide it, nor `element.hover`. For
example, VSCode’s default modern dark theme doesn’t include an
`element.hover` color after import.
Release Notes:
- Fixed an issue where the project panel’s sticky entry could appear
transparent on hover with certain themes.
We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

This PR primarily does two things:
- replace `serde_json::from_reader` with `serde_json::from_slice`, as
the latter is much much faster, even with loading the file into memory
first.
- runs the initial loading of themes and icon themes coming from
extensions in parallel instead of sequential.
Measuring the `eager_load_active_theme_and_icon_theme` method, this
drastically improves the speed at which this happens (tested this method
primarily with debug builds on my MacBook Pro, but the `Before`
measurement was also confirmed against a `release-fast` build):
- Before: ~260ms on average (in one run, it even took 600ms)
- After: ~20ms on average
Which reduces the time this method takes to load these by around ~92%.
Given that we block on this during the initial app startup, this should
drastically improve Zeds initial startup loading time. Yet, it also
improves responsiveness when installing theme extensions and trying
these.
I also replaced all other `serde_json::from_reader` implementations with
`serde_json::from_slice` and added the former to `disallowed_methods`,
given
https://github.com/serde-rs/json/issues/160#issuecomment-253446892.
Release Notes:
- Improved Zed startup speed when using themes provided by extensions
Closes https://github.com/zed-industries/zed/issues/39259
- Fixes import of `editor.fontFamily` (we were looking for the wrong
key)
- Adds basic support for the CSS font-family syntax used by VS Code,

Follow up to https://github.com/zed-industries/zed/pull/39468.
Unlike `agent_ui_font_size`, the `agent_buffer_font_size` setting does

UI font size, but rather to its default value.
Release Notes:

Before this change the active theme and icon theme were retrofitted onto
the ThemeSettings.
Now they're in their own new global (GlobalTheme::theme(cx) and
GlobalTheme::icon_theme(cx))
This lets us remove cx from the settings traits, and tidy up a few other
things along the way.

This PR adds the numeric stepper component to the settings ui and
implements some settings that rely on this component as well.
I also switched {buffer/ui}_font_weight to the `gpui::FontWeight` type
and added a manual implementation of the Schemars trait. This allows Zed
to send min, max, and default information to the JSON LSP when a user is
manually editing the settings file.
The numeric stepper elements added to the settings ui are below:
- ui font size
- ui font weight
- Buffer font size
- Buffer font weight
- Scroll sensitivity
- Fast scroll sensitivity
- Vertical scroll margin
- Horizontal scroll margin
- Inline blame padding
- Inline blame delay
- Inline blame min column
- Unnecessary code fade
- Tab Size
- Hover popover delay

Follow up to https://github.com/zed-industries/zed/pull/38726
This PR introduces the `agent_buffer_font_size` setting and renames
`agent_font_size` to `agent_ui_font_size`. This allows whoever wants
`buffer_font_size` and `agent_buffer_font_size` to match, as well as
folks who want a slightly smaller size only in the agent panel (which...
also looks just better by default!).
Release Notes:
- agent: Introduced the `agent_buffer_font_size` setting and renamed
`agent_font_size` to `agent_ui_font_size`, allowing for granular buffer
font size control in the agent panel vs. regular editors.
https://github.com/zed-industries/zed/pull/38367 introduced panic:

serde 1.0.221 introduced serde_core into the build graph, which should
render explicitly depending on serde_derive for faster build times an
obsolote method.
Besides, I'm not even sure if that worked for us. My hunch is that at
least one of our deps would have `serde` with derive feature enabled..
and then, most of the crates using `serde_derive` explicitly were also
depending on gpui, which depended on `serde`.. thus, we wouldn't have
gained anything from explicit dep on `serde_derive`

Adds a `named_directory_icons` field to the icon theme that can be used
to specify a collection of icons for collapsed and expanded folders
based on the folder name.
The `named_directory_icons` is a map from the folder name to a
`DirectoryIcons` object containing the paths to the expanded and
collapsed icons for that folder:
```json
{
"named_directory_icons": {
".angular": {
"collapsed": "./icons/folder_angular.svg",
"expanded": "./icons/folder_angular_open.svg"
}
}
}

Fixed an issue where the first frame of the `Editing` page in onboarding
would have a slight delay before rendering the first time it was

This PR separates out the associated constant `KEY` from the `Settings`
trait into a new trait `SettingsKey`. This allows for the key trait to
be derived using attributes to specify the path so that the new
`SettingsUi` derive macro can use the same attributes to determine top
level settings paths thereby removing the need to duplicate the path in
both `Settings::KEY` and `#[settings_ui(path = "...")]`

Closes #ISSUE
Initially, the `SettingsUi` trait was tied to `Settings`, however, given
that the `Settings::FileContent` type (which may be the same as the type
that implements `Settings`) will be the type that more directly maps to
the JSON structure (and therefore have the documentation, correct field
names (or `serde` rename attributes), etc) it makes more sense to have
the deriving of `SettingsUi` occur on the `FileContent` type rather than
the `Settings` type.
In order for this to work a relatively important change had to be made
to the derive macro, that being that it now "unwraps" options into their
inner type, so a field with type `Option<Foo>` where `Foo: SettingsUi`
will treat the field as if it were just `Foo`, expecting there to be a
default set in `default.json`. This imposes some restrictions on what
`Settings::FileContent` can be as seen in 1e19398 where `FileContent`
itself can't be optional without manually implementing `SettingsUi`, as
well as introducing some risk that if the `FileContent` type has
`serde(default)`, the default value will override the default value from
`default.json` in the UI even though it may differ (but it should!).
A future PR should probably replace the other settings with `FileContent
= Option<T>` (all of which currently have `T == bool`) with wrapper
structs and have `KEY = None` so the further niceties
`derive(SettingsUi)` will provide such as path renaming, custom UI, auto
naming and doc comment extraction can be used.

## Goal
This PR creates the initial settings ui structure with the primary goal
of making a settings UI that is
- Comprehensive: All settings are available through the UI
- Correct: Easy to understand the underlying JSON file from the UI
- Intuitive
- Easy to implement per setting so that UI is not a hindrance to future
settings changes
### Structure
The overall structure is settings layer -> data layer -> ui layer.
The settings layer is the pre-existing settings definitions, that
implement the `Settings` trait. The data layer is constructed from
settings primarily through the `SettingsUi` trait, and it's associated
derive macro. The data layer tracks the grouping of the settings, the
json path of the settings, and a data representation of how to render
the controls for the setting in the UI, that is either a marker value
for the component to use (avoiding a dependency on the `ui` crate) or a
custom render function.
Abstracting the data layer from the ui layer allows crates depending on
`settings` to implement their own UI without having to add additional UI
dependencies, thus avoiding circular dependencies. In cases where custom
UI is desired, and a creating a custom render function in the same crate
is infeasible due to circular dependencies, the current solution is to
implement a marker for the component in the `settings` crate, and then
handle the rendering of that component in `settings_ui`.
### Foundation
This PR creates a macro and a trait both called `SettingsUi`. The
`SettingsUi` trait is added as a new trait bound on the `Settings`
trait, this allows the type system to guarantee that all settings
implement UI functionality. The macro is used to derived the trait for
most types, and can be modified through attributes for unique cases as
well.
A derive-macro is used to generate the settings UI trait impl, allowing
it the UI generation to be generated from the static information in our
code base (`default.json`, Struct/Enum names, field names, `serde`
attributes, etc). This allows the UI to be auto-generated for the most
part, and ensures consistency across the UI.
#### Immediate Follow ups
- Add a new `SettingsPath` trait that will be a trait bound on
`SettingsUi` and `Settings`
- This trait will replace the `Settings::key` value to enable
`SettingsUi` to infer the json path of it's derived type
- Figure out how to render `Option<T> where T: SettingsUi` correctly
- Handle `serde` attributes in the `SettingsUi` proc macro to correctly
get json path from a type's field and identity

This removes around 900 unnecessary clones, ranging from cloning a few
ints all the way to large data structures and images.
A lot of these were fixed using `cargo clippy --fix --workspace
--all-targets`, however it often breaks other lints and needs to be run
again. This was then followed up with some manual fixing.
I understand this is a large diff, but all the changes are pretty
trivial. Rust is doing some heavy lifting here for us. Once I get it up
to speed with main, I'd appreciate this getting merged rather sooner
than later.
Release Notes:
- N/A
Ensures issues like #36242 and #36295 do not arise where users are
confused that the agent panel does not follow the default UI font size
whilst also keeping the possibility of customization. The agent font
size was matching the UI font size previously alredy, which makes it
easier to change it for most scenarios.
Also cleans up some related logic around modifying the font sizes.
Release Notes:
- The agent panel font size will now inherit the UI font size by default
if not set in your settings.
Closes#18565
I could use some advice on the color palette / theming. A couple
options:
1. The `drop_target_background` color could be used for the border if we
didn't use it for the background of the tab. In VSCode, the background
color of tabs doesn't change as you're dragging, there's just a border
between tabs. My only concern with this option is that the current
`drop_target_background` color is a bit subtle when used for a small
area like a border.
2. Another option could be to add a `drop_target_border` theme color,
but I don't know how much complexity this adds to implementation
(presumably all existing themes would need to be updated?).
