Closes #50212

There are two unreasonable coupling account for this issue, the coupling
of `use_tree_sitter` with `languge_aware` in

https://github.com/zed-industries/zed/blob/7892b932795911516f26f3c1c1c72249ed181ba8/crates/editor/src/element.rs#L3820-L3822
and the coupling of `language_aware` with `diagnostics` in
https://github.com/zed-industries/zed/blob/7892b932795911516f26f3c1c1c72249ed181ba8/crates/language/src/buffer.rs#L3736-L3746

Because of these couplings, when the editor stops using Tree-sitter
highlighting when `"semantic_tokens"` set to `"full"`, it also
accidentally stops fetching diagnostic information. This is why error
and warning underlines disappear.

I’ve fixed this by adding a separate `use_tree_sitter` parameter to
`highlighted_chunks`. This way, we can keep `language_aware` true to get
the diagnostic data we need, but still decide whether or not to apply
Tree-sitter highlights. I chose to fix this at the `highlighted_chunks`
level because I’m worried that changing the logic in the deeper layers
of the DisplayMap or Buffer might have too many side effects that are
hard to predict. This approach feels like a safer way to solve the
problem.

Release Notes:

- Fixed a bug where diagnostic underlines disappeared when
"semantic_tokens" set to "full"

58fec75396 Add vim/emacs modeline support (#49267)
Many editors such as vim and emacs support "modelines", a comment at the
beginning of the file that allows the file type to be explicitly
specified along with per-file specific settings

- The amount of configurations, style and settings mapping cannot be
handled in one go, so this opens up a lot of potential improvements.
- I left out the possiblity to have "zed" specific modelines for now,
but this could be potentially interesting.
- Mapping the mode or filetype to zed language names isn't obvious
either. We may want to make it configurable.

This is my first contribution to zed, be kind. I struggled a bit to find
the right place to add those settings. I use a similar approach as done
with editorconfig (merge_with_editorconfig). There might be better ways.

Closes #4762

Release Notes:

- Add basic emacs/vim modeline support.

Supersedes #41899, changes:
- limit reading to the first and last 1kb
- add documentation
- more variables handled
- add Arc around ModelineSettings to avoid extra cloning
- changed the way mode -> language mapping is done, thanks to
`modeline_aliases` language config
- drop vim ex: support
- made "Local Variables:" handling a separate commit, so we can drop it
easily
- various code style improvements

Lukas WirthandBen Kunkle b21f4a3deb Prevent remote edits from triggering edit predictions when collaborating (#51196)
BufferEvent::Edited had no way to distinguish local edits from remote
(collaboration) edits. This caused edit prediction behavior to fire on
the guest's editor when the host made document changes.

Release Notes:

- Fixed edit predictions triggering on collaboration guests when the
host edits the document.

Vitaly Slobodin a6653f0d95 language: Respect combined injection sub-ranges for language queries (#48522)
Follow-up to https://github.com/zed-industries/zed/pull/41111.

PR #41111 introduced combined injection handling, but cursor language
queries still relied on layer range selection alone. For combined
injections this can surface a language from the outer combined layer
even when the cursor is outside that language's actual included
sub-range. So, we just need to add sub-range filtering based on
anchor-aware boundary checks in the same way we did in the previous PR.
That means: apply it in `Buffer::language_at`,
`Buffer::languages_at`, and `BufferSnapshot::language_scope_at`. All
places that rely on the described behavior.

I also added some additional test cases for the `HTML+ERB` lang to
verify language resolution for HTML and Ruby positions.
Thank you!

Closes https://github.com/zed-industries/zed/issues/48358

Release Notes:

- Respect combined injection sub-ranges for language queries

4186e5764f Add vim/emacs modeline support (#44210)
Many editors such as vim and emacs support "modelines", a comment at the
beginning of the file that allows the file type to be explicitly
specified along with per-file specific settings

- The amount of configurations, style and settings mapping cannot be
handled in one go, so this opens up a lot of potential improvements.
- I left out the possiblity to have "zed" specific modelines for now,
but this could be potentially interesting.
- Mapping the mode or filetype to zed language names isn't obvious
either. We may want to make it configurable.

This is my first contribution to zed, be kind. I struggled a bit to find
the right place to add those settings. I use a similar approach as done
with editorconfig (merge_with_editorconfig). There might be better ways.

Closes #4762

Release Notes:

- Add basic emacs/vim modeline support.

Supersedes #41899, changes:
- limit reading to the first and last 1kb
- add documentation
- more variables handled
- add Arc around ModelineSettings to avoid extra cloning
- changed the way mode -> language mapping is done, thanks to
`modeline_aliases` language config
- drop vim ex: support
- made "Local Variables:" handling a separate commit, so we can drop it
easily
- various code style improvements

73d935330e Integrate scheduler crate into GPUI (#44810)
## Motivation

This PR unifies the async execution infrastructure between GPUI and
other components that depend on the `scheduler` crate (such as our cloud
codebase). By having a scheduler that lives independently of GPUI, we
can enable deterministic testing across the entire stack - testing GPUI
applications alongside cloud services with a single, unified scheduler.

## Summary

This PR completes the integration of the `scheduler` crate into GPUI,
unifying async execution and enabling deterministic testing of GPUI
combined with other components that depend on the scheduler crate.

## Key Changes

### Scheduler Integration (Phases 1-5, previously completed)
- `TestDispatcher` now delegates to `TestScheduler` for timing, clock,
RNG, and task scheduling
- `PlatformScheduler` implements the `Scheduler` trait for production
use
- GPUI executors wrap scheduler executors, selecting `TestScheduler` or
`PlatformScheduler` based on environment
- Unified blocking logic via `Scheduler::block()`

### Dead Code Cleanup
- Deleted orphaned `crates/gpui/src/platform/platform_scheduler.rs`
(older incompatible version)

## Intentional Removals

### `spawn_labeled` and `deprioritize` removed
The `TaskLabel` system (`spawn_labeled`, `deprioritize`) was removed
during this integration. It was only used in a few places for test
ordering control.

cc @maxbrunsfeld @as-cii - The new priority-weighted scheduling in
`TestScheduler` provides similar functionality through
`Priority::High/Medium/Low`. If `deprioritize` is important for specific
test scenarios, we could add it back to the scheduler crate. Let me know
if this is blocking anything.

### `start_waiting` / `finish_waiting` debug methods removed
Replaced by `TracingWaker` in `TestScheduler` - run tests with
`PENDING_TRACES=1` to see backtraces of pending futures when parking is
forbidden.

### Realtime Priority removed
The realtime priority feature was unused in the codebase. I'd prefer to
reintroduce it when we have an actual use case, as the implementation
(bounded channel with capacity 1) could potentially block the main
thread. Having a real use case will help us validate the design.

## Testing
- All GPUI tests pass
- All scheduler tests pass
- Clippy clean

## Architecture

Lukas Wirth ccce05d25c language: Fix reparse timeout not actually working (#45347)
We use `block_with_timeout` to give the reparse task a millisecond to
complete, and if it takes longer we put the work off to the background.
The reason for this is that we want tree-sitter based features to feel
snappy.
The reparse task is non-cooperative though, it has no yield points,
giving us no place to actually check for our timeout, meaning we will
always drive it to completion and block for the entire duration.
This kicks out the `block_with_timeout` in favor of using the treesitter
progress callback to handle timeouts instead.

- Improved responsiveness with very language language files on edits

tidely 387059c6b2 language: Add LanguageName::new_static to reduce allocations (#44380)
Implements a specialized constructor `LanguageName::new_static` for
`&'static str` which reduces allocations.

`LanguageName::new` always backs the underlying `SharedString` with an
owned `Arc<str>` even when a `&'static str` is passed. This makes us
allocate each time we create a new `LanguageName` no matter what.
Creating a specialized constructor for `&'static str` allows us to
essentially construct them for free.

Additional change:
Encourages using explicit constructors to avoid needless allocations.
Currently there were no instances of this trait being called where the
lifetime was not `'static` saving another 48 locations of allocation.

```rust
impl<'a> From<&'a str> for LanguageName {
    fn from(str: &'a str) -> Self {
        Self(SharedString::new(str))
    }
}

// to 

impl From<&'static str> for LanguageName {
    fn from(str: &'static str) -> Self {
        Self(SharedString::new_static(str))
    }
}

7e341bcf94 Support bracket colorization (rainbow brackets) (#43172)
Deals with https://github.com/zed-industries/zed/issues/5259

Highlights brackets with different colors based on their depth.
Uses existing tree-sitter queries from brackets.scm to find brackets,
uses theme's accents to color them.


https://github.com/user-attachments/assets/cc5f3aba-22fa-446d-9af7-ba6e772029da

1. Adds `colorize_brackets` language setting that allows, per language
or globally for all languages, to configure whether Zed should color the
brackets for a particular language.

Disabled for all languages by default.

2. Any given language can opt-out a certain bracket pair by amending the
brackets.scm like `("\"" @open "\"" @close) ` -> `(("\"" @open "\""
@close) (#set! rainbow.exclude))`

3. Brackets are using colors from theme accents, which can be overridden
as

```jsonc
"theme_overrides": {
  "One Dark": {
    "accents": ["#ff69b4", "#7fff00", "#ff1493", "#00ffff", "#ff8c00", "#9400d3"]
  }
},
```

Release Notes:

- Added bracket colorization (rainbow brackets) support. Use
`colorize_brackets` language setting to enable.

Vitaly Slobodin cd87307289 language: Fix language detection for injected syntax layers (#41111)
Closes #40632

**TL;DR:** The `wrap selections in tag` action was unavailable in ERB
files, even when the cursor was positioned in HTML content (outside of
Ruby code blocks). This happened because `syntax_layer_at()` incorrectly
returned the Ruby language for positions that were actually in HTML.
**NOTE:** I am not familiar with that part of Zed so it could be that
the fix here is completely incorrect.

Previously, `syntax_layer_at` incorrectly reported injected languages
(e.g., Ruby in ERB files) even when the cursor was in the base language
content (HTML). This broke actions like `wrap selections in tag` that
depend on language-specific configuration.

The issue had two parts:
1. Missing start boundary check: The filter only checked if a layer's
end was after the cursor (`end_byte() > offset`), not if it started
before, causing layers outside the cursor position to be included. See
the `BEFORE` video: when I click on the HTML part it reports `Ruby`
language instead of `HTML`.
2. Wrong boundary reference for injections: For injected layers with
`included_sub_ranges` (like Ruby code blocks in ERB), checking the root
node boundaries returned the entire file range instead of the actual
injection ranges.

This fix:
- Adds the containment check using half-open range semantics [start,
end) for root node boundaries. That ensures proper reporting of the
detected language when a cursor (`|`) is located right after the
injection:

   ```
   <body>
    <%= yield %>|
  </body>
   ```

- Checks `included_sub_ranges` for injected layers to determine if the
cursor is actually within an injection
- Falls back to root node boundaries for base layers without sub-ranges.
This is the original behavior.

Fixes ERB language support where actions should be available based on
the cursor's actual language context. I think that also applies to some
other template languages like HEEX (Phoenix) and `*.pug`. On short
videos below you can see how I navigate through the ERB template and the
terminal on the right outputs the detected language if you apply the
following patch:

03f9cf4414 Represent relative paths using a dedicated, separator-agnostic type (#38744)
Closes https://github.com/zed-industries/zed/issues/38690
Closes #37353

### Background

On Windows, paths are normally separated by `\`, unlike mac and linux
where they are separated by `/`. When editing code in a project that
uses a different path style than your local system (e.g. remoting from
Windows to Linux, using WSL, and collaboration between windows and unix
users), the correct separator for a path may differ from the "native"
separator.

Previously, to work around this, Zed converted paths' separators in
numerous places. This was applied to both absolute and relative paths,
leading to incorrect conversions in some cases.

### Solution

Many code paths in Zed use paths that are *relative* to either a
worktree root or a git repository. This PR introduces a dedicated type
for these paths called `RelPath`, which stores the path in the same way
regardless of host platform, and offers `Path`-like manipulation APIs.
RelPath supports *displaying* the path using either separator, so that
we can display paths in a style that is determined at runtime based on
the current project.

The representation of absolute paths is left untouched, for now.
Absolute paths are different from relative paths because (except in
contexts where we know that the path refers to the local filesystem)
they should generally be treated as opaque strings. Currently we use a
mix of types for these paths (std::path::Path, String, SanitizedPath).

effect is that some settings which did not make sense in project
settings files are no-longer read from there. (For example the inline
blame settings)

b8c30f448f Improve Tab Map performance (#32243)
## Context

While looking into: #32051 and #16120 with instruments, I noticed that
`TabSnapshot::to_tab_point` and `TabSnapshot::to_fold_point` are a
common bottleneck between the two issues. This PR takes the first steps
into closing the stated issues by improving the performance of both
those functions.

### Method

`to_tab_point` and `to_fold_point` iterate through each character in
their rows to find tab characters and translate those characters into
their respective transformations. This PR changes this iteration to take
advantage of the tab character bitmap in the `Rope` data structure and
goes directly to each tab character when iterating.

The tab bitmap is now passed from each layer in-between the `Rope` to
the `TabMap`.

### Testing 

I added several randomized tests to ensure that the new `to_tab_point`
and `to_fold_point` functions have the same behavior as the old methods
they're replacing. I also added `test_random_chunk_bitmap` on each layer
the tab bitmap is passed up to the `TabMap` to make sure that the bitmap
being passed is transformed correctly between the layers of
`DisplayMap`.

`test_random_chunk_bitmap` was added to these layers:
- buffer
- multi buffer
- custom_highlights
- inlay_map
- fold_map

## Benchmarking 

I setup benchmarks with criterion that is runnable via `cargo bench -p
editor --profile=release-fast`. When benchmarking I had my laptop
plugged in and did so from the terminal with a minimal amount of
processes running. I'm also on a m4 max

### Results 

#### To Tab Point

Went from completing 6.8M iterations in 5s with an average time of
`736.13 ns` to `683.38 ns` which is a `-7.1875%` improvement

#### To Fold Point

Went from completing 6.8M iterations in 5s with an average time of
`736.55 ns` to `682.40 ns` which is a `-7.1659%` improvement

#### Editor render 

Went from having an average render time of `62.561 µs` to `57.216 µs`
which is a `-8.8248%` improvement

#### Build Buffer with one long line

Went from having an average buffer build time of `3.2549 ms` to `3.2635
ms` which is a `+0.2151%` regression within the margin of error

#### Editor with 1000 multi cursor input 

Went from having an average edit time of `133.05 ms` to `122.96 ms`
which is a `-7.5776%` improvement

Nathan SoboandAntonio Scandurra 1ae326432e Extract a scheduler crate from GPUI to enable unified integration testing of client and server code (#37326)
Extracts and cleans up GPUI's scheduler code into a new `scheduler`
crate, making it pluggable by external runtimes. This will enable
deterministic integration testing with cloud components by providing a
unified test scheduler across Zed and backend code. In Zed, it will
replace the existing GPUI scheduler for consistent async task management
across platforms.

## Changes

- **Core Implementation**: `TestScheduler` with seed-based
randomization, session tracking (`SessionId`), and foreground/background
task separation for reproducible testing.
- **Executors**: `ForegroundExecutor` (!Send, thread-local) and
`BackgroundExecutor` (Send, with blocking/timeout support) as
GPUI-compatible wrappers.
- **Clock and Timer**: Controllable `TestClock` and future-based `Timer`
for time-sensitive tests.
- **Testing APIs**: `once()`, `with_seed()`, and `many()` methods for
configurable test runs.
- **Dependencies**: Added `async-task`, `chrono`, `futures`, etc., with
updates to `Cargo.toml` and lock file.

## Benefits

- **Integration Testing**: Facilitates reliable async tests involving
cloud sessions, reducing flakiness via deterministic execution.
- **Pluggability**: Trait-based design (`Scheduler`) allows easy
integration into non-GPUI runtimes while maintaining GPUI compatibility.
- **Cleanup**: Refactors GPUI scheduler logic for clarity, correctness
(no `unwrap()`, proper error handling), and extensibility.

Follows Rust guidelines; run `./script/clippy` for verification.

- [x] Define and test a core scheduler that we think can power our cloud
code and GPUI
- [ ] Replace GPUI's scheduler

tidely 7bdc99abc1 Fix clippy::redundant_clone lint violations (#36558)
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.

claytonrcarter 1f4c9b9427 language: Update block_comment and documentation comment (#34861)
As suggested in https://github.com/zed-industries/zed/pull/34418, this
proposes various changes to language configs to make block comments and
doc-block-style comments more similar. In doing so, it introduces some
breaking changes into the extension schema.

This change is needed to support the changes I'm working on in #34418,
to be able to support `rewrap` in block comments like `/* really long
comment ... */`. As is, we can do this in C-style doc-block comments (eg
`/** ... */`) because of the config in `documentation`, but we can't do
this in regular block comments because we lack the info about what the
line prefix and indentation should be.

And while I was here, I did various other clean-ups, many of which feel
nice but are optional.

I would love special attention on the changes to the schema, version and
related changes; I'm totally unfamiliar with that part of Zed.

**Summary of changes**
- break: changes type of `block_comment` to same type as
`documentation_comment` (**this is the important change**)
- break: rename `documentation` to `documentation_comment` (optional,
but improves consistency w/ `line_comments` and `block_comment`)
- break/refactor?: removes some whitespace in the declaration of
`block_comment` delimiters (optional, may break things, need input; some
langs had no spaces, others did)
- refactor: change `tab_size` from `NonZeroU32` to just a `u32` (some
block comments don't seem to need/want indent past the initial
delimiter, so we need this be 0 sometimes)
- refactor: moves the `documentation_comment` declarations to appear
next to `block_comment`, rearranges the order of the fields in the TOML
for `documentation_comment`, rename backing `struct` (all optional)

**Future scope**
I believe that this will also allow us to extend regular block comments
on newline – as we do doc-block comments – but I haven't looked into
this yet. (eg, in JS try pressing enter in both of these: `/* */` and
`/** */`; the latter should extend w/ a `*` prefixed line, while the
former does not.)

Release Notes:

- BREAKING CHANGE: update extension schema version from 1 to 2, change
format of `block_comment` and rename `documentation_comment`

Michael Sloan 5fafab6e52 Migrate to schemars version 1.0 (#33635)
The major change in schemars 1.0 is that now schemas are represented as
plain json values instead of specialized datatypes. This allows for more
concise construction and manipulation.

This change also improves how settings schemas are generated. Each top
level settings type was being generated as a full root schema including
the definitions it references, and then these were merged. This meant
generating all shared definitions multiple times, and might have bugs in
cases where there are two types with the same names.

Now instead the schemar generator's `definitions` are built up as they
normally are and the `Settings` trait no longer has a special
`json_schema` method. To handle types that have schema that vary at
runtime (`FontFamilyName`, `ThemeName`, etc), values of
`ParameterizedJsonSchema` are collected by `inventory`, and the schema
definitions for these types are replaced.

To help check that this doesn't break anything, I tried to minimize the
overall [schema
diff](https://gist.github.com/mgsloan/1de549def20399d6f37943a3c1583ee7)
with some patches to make the order more consistent + schemas also
sorted with `jq -S .`. A skim of the diff shows that the diffs come
from:

* `enum: ["value"]` turning into `const: "value"`
* Differences in handling of newlines for "description"
* Schemas for generic types no longer including the parameter name, now
all disambiguation is with numeric suffixes
* Enums now using `oneOf` instead of `anyOf`.

claytonrcarter f4b361f04d language: Select language based on longest matching path extension (#29716)
Closes #8408  
Closes #10997

This is a reboot of [my original
PR](https://github.com/zed-industries/zed/pull/11697) from last year. I
believe that I've addressed all the comments raised in that original
review, but Zed has changed a lot in the past year, so I'm sure there
will be some new stuff to consider too.

- updates the language matching and lookup to consider not just "does
the suffix/glob match" but also "... and is it the longest such match"
- adds a new `LanguageCustomFileTypes` struct to pass user globs from
settings to the registry
- _minor/unrelated:_ updates a test for the JS extension that wasn't
actually testing what is intended to
- _minor/unrelated:_ removed 2 redundant path extensions from the JS
lang extension

**Languages that may use this**

- Laravel Blade templates use the `blade.php` compound extension
-
[apparently](https://github.com/zed-industries/zed/issues/10765#issuecomment-2091293304)
Angular uses `component.html`
  - see also https://github.com/zed-industries/extensions/issues/169
- _hypothetically_ someone could publish a "JS test" extension w/ custom
highlights and/or snippets; many JS tests use `test.js` or `spec.js`

**Verifying these changes**

I added a number of assertions for this new behavior, and I also
confirmed that the (recently patched) [Laravel Blade
extension](https://github.com/bajrangCoder/zed-laravel-blade) opens as
expected for `blade.php` files, whereas on `main` it does not.

cc @maxbrunsfeld (reviewed my original PR last year), @osiewicz and
@MrSubidubi (have recently been in this part of the code)

Release Notes:

- Added support for "compound" file extensions in language extensions,
such `blade.php` and `component.html`. Closes #8408 and #10997.

Vinicius Akira 29f0762b6c Add block_comment to JS, TSX, and TS (#31400)
This is the first step of ["Solution proposal for folding multiline
comments with no
indentation"](https://github.com/zed-industries/zed/discussions/31395):

> 1. Add block_comment in the config.toml for the languages javascript,
typescript, tsx. These are simple languages for this feature, and I am
already familiar with them.

The next step will be:

> 2. Modify the function `crease_for_buffer_row` in `DisplaySnapshot` to
handle multiline comments. `editor::fold` and `editor::fold_all` will
handle multiline comments after this change. To my knowledge,
`editor::unfold`, `editor::unfold_all`, and the **unfold** indicator in
the gutter will already work after folding, but there will be no
**fold** indicator.

Smit Barmase a50fbc9b5c language: Fix language_scope_at for markdown code comments (#29230)
Closes #29176

This PR fix an issue where uncommenting a code block in Markdown would
add Markdown comments instead of removing the language-specific
comments.

Why?
`language_scope_at` for comments in a code block in Markdown would
result in the language being detected as Markdown. This happens because
the smallest range, such as `//` or `#` on the Markdown layer, is
preferred over `// whole comment line` for any other language. This
results in language detection as Markdown for that point.

To fix this, we also use a depth factor and try to prefer the layer with
greater depth over one with lesser depth. In this case, the code block's
language depth would be preferred over Markdown. The smallest range is
now used as a tiebreaker.

Added test for this case.

Release Notes:

- Fixed issue where uncommenting a code block in Markdown would add
Markdown comments instead of removing the language comments.

Smit Barmase 69d7ea7b60 buffer: Fix broken auto indent when pasting code starting with new line (#28134)
Closes #26907

Currently, in case of new line to find delta, it is comparing old first
line indent with new second line indent. This results into incorrect
indentation. This PR fixes this delta calculation by passing correct
second line indent in that particular case.

###  DISCLAIMER

> As of 6th March 2025, debugger is still in development. We plan to
merge it behind a staff-only feature flag for staff use only, followed
by non-public release and then finally a public one (akin to how Git
panel release was handled). This is done to ensure the best experience
when it gets released.
