This extracts a `language_core` crate from the existing `language`
crate, and creates a `grammars` data crate. The goal is to separate
tree-sitter grammar infrastructure, language configuration, and LSP
adapter types from the heavier buffer/editor integration layer in
`language`.
## Motivation
The `language` crate pulls in `text`, `theme`, `settings`, `rpc`,
`task`, `fs`, `clock`, `sum_tree`, and `fuzzy` — all of which are needed
for buffer integration (`Buffer`, `SyntaxMap`, `Outline`,
`DiagnosticSet`) but not for grammar parsing or language configuration.
Extracting the core types lets downstream consumers depend on
`language_core` without pulling in the full integration stack.
## Dependency graph after extraction
```
language_core ← gpui, lsp, tree-sitter, util, collections
grammars ← language_core, rust_embed, tree-sitter-{rust,python,...}
language ← language_core, text, theme, settings, rpc, task, fs, ...
languages ← language, grammars
```
## What moved to `language_core`
- `Grammar`, `GrammarId`, and all query config/builder types
- `LanguageConfig`, `LanguageMatcher`, bracket/comment/indent config
types
- `HighlightMap`, `HighlightId` (theme-dependent free functions
`highlight_style` and `highlight_name` stay in `language`)
- `LanguageName`, `LanguageId`
- `LanguageQueries`, `QUERY_FILENAME_PREFIXES`
- `CodeLabel`, `CodeLabelBuilder`, `Symbol`
- `Diagnostic`, `DiagnosticSourceKind`
- `Toolchain`, `ToolchainScope`, `ToolchainList`, `ToolchainMetadata`
- `ManifestName`
- `SoftWrap`
- LSP data types: `BinaryStatus`, `ServerHealth`,
`LanguageServerStatusUpdate`, `PromptResponseContext`, `ToLspPosition`
## What stays in `language`
- `Buffer`, `BufferSnapshot`, `SyntaxMap`, `Outline`, `DiagnosticSet`,
`LanguageScope`
- `LspAdapter`, `CachedLspAdapter`, `LspAdapterDelegate` (reference
`Arc<Language>` and `WorktreeId`)
- `ToolchainLister`, `LanguageToolchainStore` (reference `task` and
`settings` types)
- `ManifestQuery`, `ManifestProvider`, `ManifestDelegate` (reference
`WorktreeId`)
- Parser/query cursor pools, `PLAIN_TEXT`, point conversion functions
## What the `grammars` crate provides
- Embedded `.scm` query files and `config.toml` files for all built-in
languages (via `rust_embed`)
- `load_queries(name)`, `load_config(name)`,
`load_config_for_feature(name, grammars_loaded)`, and `get_file(path)`
functions
- `native_grammars()` for tree-sitter grammar registration (behind
`load-grammars` feature)
## Pre-cleanup (also in this PR)
- Removed unused `Option<&Buffer>` from
`LspAdapter::process_diagnostics`
- Removed unused `&App` from `LspAdapter::retain_old_diagnostic`
- Removed `fs: &dyn Fs` from `ToolchainLister` trait methods
(`PythonToolchainProvider` captures `fs` at construction time instead)
- Moved `Diagnostic`/`DiagnosticSourceKind` out of `buffer.rs` into
their own module
## Backward compatibility
The `language` crate re-exports everything from `language_core`, so
existing `use language::Grammar` (etc.) continues to work unchanged. The
only downstream change required is importing `CodeLabelExt` where
`.fallback_for_completion()` is called on the now-foreign `CodeLabel`
type.

This PR refactors the highlight map capture name resolution to be faster
and more predictable. Speficically,
- it changes the capture name matching to explicit prefix matching
(e.g., `function.call.whatever.jsx` will now be matched by only
`function`, `function.call`, `function.call.whatever` and
`function.call.whatever.jsx`). This matches the behavior VSCode has
- resolving highlights is now much more efficient, as we now look up
captures in a BTreeMap as opposed to searching in a Vector for these.
This substantially improves the performance for resolving capture names
against themes. With the benchmark added here for creating the
HighlightMap, we see quite some improvements:
```

Performance has improved.

1 (1.00%) low mild
```
For large themes and many capture names, the revised approach is much
faster.
With that in place, we can also add better fallbacks whenever we change
tokens, since e.g. a change from `@variable` to `@preproc` would
previously cause tokens to not be highlighted at all, whereas now we can
add fallbacks for such cases more efficiently. I'll add this later on to
this PR.

Release Notes:
- Improved resolution speed of theme highlight capture names. This might
change highlighting in some rare edge cases, but should overall make
highlighting more predicatable. Theme captures will now follow a strict
prefix matching, so e.g. function.call.decorator.jsx` will now be
matched by only `function`, `function.call`, `function.call.decorator`
and `function.call.decorator.jsx` with the most specific capture always
taking precedence.

Mentioned in #47258
Release Notes:
- Added hotkey options and actions for toggling light and dark theme.
- Add default keymap as `cmd/ctrl+k cmd/ctrl+shift+t`
`.cppm` is the widely used extension for C++20 module interface units,
supported by MSVC, Clang, and GCC. Currently Zed doesn't recognize it as
C++, so users get no syntax highlighting or LSP support.
Changes:
`crates/languages/src/cpp/config.toml`: add cppm to path_suffixes
`crates/theme/src/icon_theme.rs`: add cppm to the C++ icon matcher
https://github.com/search?q=path%3A*.cppm&type=code

* Add a dedicated `vim.yank.background` theme color for the yank
highlight, which was previously hardcoded to
`editor.document_highlight.read_background`.
* When a theme doesn't define `vim.yank.background`, it falls back to
`editor.document_highlight.read_background` for backwards
compatibility.
* The VS Code theme importer maps `editor.rangeHighlightBackground` to
this new color.
Release Notes:
- Added configurable `vim.yank.background` theme color for vim yank
background highlight

The binary search insertion scheme in `highlight_text` works fine for
small numbers of elements but does not handle large amounts of ranges
well, as that will cause constant memcpying of the latter half of the
vec. Bracket colorization tends to have a huge amount of entries though,
so this can cause massive lags on the foreground thread. The better
approach here is to just collect all elements and re-sort them once.
Release Notes:
- Reduced mini-stutters occuring due to large amount of bracket
colorization in big buffers and agent diffs
Part of #7450

Closes #ISSUE
Moves the settings content definitions into their own crate, so that
they are compiled+cached separately from settings, primarily to avoid
recompiles due to changes in gpui. In that vain many gpui types such as
font weight/features, and `SharedString` were replaced in the content
crate, either with `*Content` types for font/modifier things, or
`String`/`Arc<str>` for `SharedString`. To make the conversions easy a
new trait method in the settings crate named `IntoGpui::into_gpui`
allows for `into()` like conversions to the gpui types in
`from_settings` impls.

Closes https://github.com/zed-industries/zed/issues/44091
The issue here was that we were missing a proper default for
`ThemeSelection`. This is a disadvantage of not having the defaults in
code but actually in the `default.json`, so this here basically copies
the default from the `default.json` into code for the settings UI to
work properly.
Release Notes:
- Fixed an issue where the theme was not configurable from the settings
UI if no theme was configured prior.
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
<img width="1502" height="430" alt="image"
src="https://github.com/user-attachments/assets/1a8d5b71-449e-44cd-bc87-d6b65bfca545"
/>
### 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`](https://github.com/zed-industries/zed/blob/02b2aa6c50c03d3005bec2effbc9f87161fbb1e8/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.

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

key)

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

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

`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.

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`

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

level settings paths thereby removing the need to duplicate the path in
both `Settings::KEY` and `#[settings_ui(path = "...")]`
