Before, each edit in a 50 MB plaintext file would trigger a lot of
anchor calculations (as chunk is 50 lines only) done on main thread +
did extra work when no language grammar or brackets were available.

The PR now moves all anchor calculations into `computed_chunks:
Mutex<HashMap<usize, RowChunk>>,` cache miss.
`TreeSitterData` is wrapped in `Arc` and shared as a part of the
snapshot, hence the need for `Mutex` and internal mutability here.

Trace after the changes:

saberoueslatiandKirill Bulatov 97b51f2620 language: Fix JSON rainbow bracket colors across chunks (#60741)
## Context

JSON rainbow bracket colors could shift across row chunk boundaries when
large ancestor objects were omitted by the bounded tree-sitter bracket
query window. This fixes the chunk-local depth reset by caching bracket
chunk data together with the active bracket stack after each chunk, then
using that inherited stack when later chunks are computed. For JSON
object braces that are too large for the bounded query, the
implementation recovers active ancestor `{...}` pairs from the syntax
tree so sibling object braces keep the same color even when jumping
directly to a later chunk.

Closes #50185

## How to Review

`crates/language/src/buffer/row_chunk.rs` adds indexed access to row
chunks so bracket cache computation can walk from the nearest cached
chunk up to the requested chunk.

`crates/language/src/buffer.rs` changes bracket range caching from
storing only per-chunk matches to storing per-chunk matches plus the
active bracket stack after that chunk. It preserves the existing bounded
query and greedy-match repair behavior, while adding JSON-specific
ancestor recovery for large object braces omitted by
`MAX_BYTES_TO_QUERY`.

`crates/language/src/buffer_tests.rs` adds a JSON regression fixture
that exceeds `MAX_BYTES_TO_QUERY`, fetches a later chunk before earlier
chunks, and verifies all same-depth sibling object braces keep the same
`color_index` across row chunks.

Miguel Raz Guzmán Macedo 6c4b9ae965 Replace panicking unwraps in iterator and Option chains (#61277)
# Objective

Remove `.unwrap()` calls in iterator/`Option` chains that could panic at
runtime.

## Solution

Use `and_then`/`filter_map` with `.ok()` for fallible downcasts
(`entry_view_state.rs`) and keystroke parsing (`vim/command.rs`); use a
descriptive `expect` in `suggest_autoindents` where the invariant is
intentional (`buffer.rs`).

## Testing

- `cargo test -p language buffer` (69 passed)
- `cargo test -p vim command` (26 passed)

Tautik AgrahariandKirill Bulatov 756e764b90 project: Track inlay hint / code lens / document symbol registrations by ID (#55340)
extends the precedent set by #43703 (thanks @reflectronic) so that
`textDocument/inlayHint`, `textDocument/codeLens`, and
`textDocument/documentSymbol` correctly track multiple dynamic
registrations by id. previously each register call overwrote the slot on
`ServerCapabilities`, and unregister either silently did nothing
(inlayHint, documentSymbol — no match arm) or wiped the entire
capability (codeLens). now each method keeps its own id-keyed map on
`DynamicRegistrations`; the field on `ServerCapabilities` is cleared
only when the last registration is removed.

textDocument-sync notifications (`didChange`/`didSave`/`willSave`) are
deliberately out of scope — their fan-out semantics are ambiguous in the
spec and were flagged on @smitbarmase's earlier exploration in #36876.

verified with `cargo check -p project -p lsp -p editor`, `cargo test -p
project --test integration -- multi_registration` (3/3 passing), and
`cargo fmt -p project`.

closes part of #37838.

Release Notes:

- Improved support for language servers that dynamically register inlay
hints, code lens, or document symbols multiple times.

Apoorva Verma 708b65e373 Fix hard-tab block autoindent skipping unindented lines (#60406)
# Objective

Fixes #59979

With hard tabs on, expanding a multi-line snippet only re-indents the
lines that already start with a tab. Anything with no leading whitespace
(closing brackets, mostly) stays at column 0.

## Solution

Block autoindent shifts each line by the first line's delta, but only
when the line's indent kind matches the target kind. A line with no
indentation defaults to `IndentKind::Space`, so under hard tabs it never
matches and gets skipped. An empty indent doesn't really have a kind, so
I let it adopt the target kind before the check. Lines that actually
have space indentation in a tab buffer are still left alone. Normalizing
those felt like a bigger question than this bug, happy to look at it
separately if wanted.

## Testing

New `test_autoindent_block_mode_with_hard_tabs`, same shape as the
snippet in the issue. Fails on main (closing brace stays at column 0),
passes with the fix. `cargo test -p language` and `-p editor` are green,
clippy and fmt too.

G36maidandKirill Bulatov 2a3f40aba8 Add range-based whitespace and newline removal to buffer formatting (#53942)
## Summary

When formatting specific ranges (e.g. via Format Selections), trailing
whitespace removal and final newline enforcement currently operate on
the entire file. This PR makes these operations range-aware, so they
only affect lines within the target ranges.

As noted in #16509, users want `remove_trailing_whitespace_on_save` and
`ensure_final_newline_on_save` to suppress jitter by only touching
changed lines. This PR provides the foundational infrastructure for that
— range-based whitespace and newline operations — which a follow-up PR
will wire into the `format_on_save` modifications mode.

## Changes

- Added `remove_trailing_whitespace_in_ranges` and
`ensure_final_newline_in_range` to `Buffer`
- When a `FormattableBuffer` has ranges set, whitespace and newline
operations now use the range-based variants
- `format_ranges_via_lsp` returns `Ok(None)` instead of an error when
the LSP doesn't support range formatting
- Extracted `anchor_ranges_to_row_ranges` helper to deduplicate
conversion logic

<details><summary>Tests (4)</summary>

- `test_trailing_whitespace_in_ranges` — only modified lines have
whitespace removed
- `test_trailing_whitespace_empty_ranges` — empty ranges → no changes
- `test_final_newline_modified_last_line` — newline added when last line
is in range
- `test_final_newline_unmodified_last_line` — newline not added when
last line is outside range

</details>

6a6fcbebc4 Add preview to pickers and make them resizable (#59604)
Overhauls Zed's pickers to make them resizable and give them a preview.

Closes #8279 

### Background
The most requested Zed feature has the last year has been a [Telescope
like search box](https://github.com/zed-industries/zed/issues/8279)
[discussion](https://github.com/zed-industries/zed/discussions/22581).
To understand why this is so popular we need to understand search can
serve thee goals:
- Navigation: fuzzy search is faster & easier then clicking in a file
tree
- Exploration: example, find a function by a word in its doc comment
- Collecting: example, getting a list of functions to change

The project search which shows results in a multibuffer is the perfect
way to operate on a list of items. Navigation and Exploration need a lot
of context around each result and offer fast navigation between them.
For both of these live searching is also critical.

The `telescope UI` is a picker with a preview to the right or below.
It's offered in various editors and IDE's most famously Neovim (through
the Telescope plugin), IntelliJ (natively), Helix (natively) and of
course VScode (plugins) and it's _many_ forks.

While having a UI like that for text search (our project search) is most
requested the UX pattern is applied widely, from `find_all_references`
to `bookmarks`. It enhances most pickers. Note that we have over 50
different picker modals!

The community has tried to build something like this for Zed:
- https://github.com/zed-industries/zed/pull/44530
- https://github.com/zed-industries/zed/pull/45307
- https://github.com/zed-industries/zed/pull/46478
- https://github.com/zed-industries/zed/pull/43790

These all became huge PR's that we could not merge for various reasons.
This is a really hard feature to integrate in Zed!
This PR got started as https://github.com/zed-industries/zed/pull/46478
and supercedes that.

### Design
- Extend pickers to support an optional preview with minimal changes to
the pickers themselves.
- Make pickers resizable.
- Complement the existing search do not replace it by having both UI's
share the underlying search and allow freely switching between them.
- Allow extending the preview to things other then files.
- Maintain a clean design on all the pickers.

### Heigh level Implementation overview
- Adds an `Option<Preview>` to `Picker`
- Gives `PickerDelegate` a method to communicate a preview to the Picker
- Overhaul the way pickers are drawn to allow for resizing them.
Implemented on the `Shape` and `SizeBouds` structs.
- Adds a high level way to draw the `footer` and `editor` so we do not
need to change much to the pickers.
- Adds a new text finder Picker
- Adds a way to take a running search from project search and hand it to
the text finder Picker and the other way round
- Give the file finder a preview

### Next steps
A more detailed list and how to help out will be added to the tracking
issue for [Pickes with
previews](https://github.com/zed-industries/zed/issues/56037)
- Add more previews to more pickers!
- Enable selectioning multiple items in pickers and performing actions
on those
- Open selected items in a multibuffer
- Add a way to restore the last picker
- Make popovers (picker attached to some menu) resizable as well

guidelines)
- [x] Tests cover the new/changed behavior
- [x] Performance impact has been considered and is acceptable

## Showcase
TODO (will be done post merge)

---

Release Notes:
- Added resizing via dragging to all picker modals. 
- Added a preview to the File finder, the preview can be to the right or
below.
- Added a Text finder picker with a preview as alternative project
search UI. The search is shared and allowes switch between UIs while
running.

saberoueslati 7d516a1a91 Anchor sticky scroll to symbol name rows (#56333)
## Context

Sticky scroll was anchoring multiline signatures to the first outline
context row instead of the row containing the symbol name, which could
leave the sticky header showing unhelpful context. This change carries
each outline item’s `selection_range` through the tree-sitter, LSP,
multi-buffer, and editor paths, then uses that range to choose the
sticky header row.

This is intended to improve sticky scroll generically, not only for one
language. It should help wherever symbol data distinguishes the symbol
name from the larger symbol range:
- tree-sitter outlines that provide a distinct `@name` capture
- LSP document symbols whose `selectionRange` is more precise than
`range`

The actual improvement is still language-dependent, because it relies on
the quality of each language’s outline query or language server symbol
metadata.

Closes #55587

## How to Review

`crates/language/src/outline.rs`, `crates/language/src/buffer.rs`, and
`crates/language/src/buffer_tests.rs`: Adds `selection_range` to
tree-sitter outline items and verifies that multiline signatures can
anchor sticky scroll on the symbol-name row while preserving the
existing displayed outline text.

`crates/project/src/lsp_store/document_symbols.rs`: Threads LSP document
symbol `selection_range` into `OutlineItem`, keeping enriched labels and
highlight ranges intact while preserving the distinction between the
full symbol range and the selected name range.

`crates/multi_buffer/src/multi_buffer.rs`,
`crates/editor/src/document_symbols.rs`, `crates/editor/src/editor.rs`,
`crates/outline/src/outline.rs`, and
`crates/outline_panel/src/outline_panel.rs`: Propagates
`selection_range` through the places that remap outline items between
buffers, multi-buffers, editors, and outline views.

`crates/editor/src/element.rs` and `crates/editor/src/editor_tests.rs`:
Uses `selection_range` when computing sticky header rows and adds a
regression test covering a multiline signature case from the issue.

`crates/language/Cargo.toml` and `Cargo.lock`: Adds `tree-sitter-c` for
the language-level regression test fixture.

Galen EliasandLukas Wirth 550a42233b Fix incorrect mask in BufferChunks::next (#57544)
I noticed while working on a personal project which derives some logic
from the core Zed stack that I was getting very unexpected results out
of BufferChunks::next when walking through formatted chunks.

The code calculates the mask for the `tabs`, `chars`, and `newlines`
masks incorrectly, making the mask far too large when we are extracting
chunks when chunk_start != 0.

I believe the reason that this isn't a problem in Zed is that the
InlayMap ends up re-masks all the bitmasks before passing things up the
stack, so covers up the problem, preventing it from causing any damage.
It appears this isn't caught in tests because this only happens when
extracting chunks with formatting, during which we offset our retrieval
by next_capture_start, and the current chunks tests don't use
formatting.

I think the fix is sound. The test is maybe not super ideal, but I
wanted to demonstrate the issue in the pull request.

If we process the following text by chunks:
```rust
use std::cmp::Eq;
```

The first chunk is 'use ' with the chars mask being 0b1111. The second
chunk is 'std' with the chars mask being 0b1111111 when it should just
be 0b111.

7a469725d3 Refactor BufferDiff to allow multiple diffs to share the same base text buffer (#58266)
This PR changes how base texts are managed by the `buffer_diff` crate,
to enable keeping two diff entities alive that share the same base text
buffer entity. Previously, each diff owned its own base text buffer and
edited it when calling `BufferDiff::set_snapshot`, so the only way to
reuse the same base text between two diffs was to have two independent
buffers for it, which is pretty inefficient.

After this PR, each diff still has a base text buffer, but
`set_snapshot` doesn't edit it. Instead, that responsibility moves into
the caller. For updating the base text buffer, this PR also introduces a
new pair of APIs, `Buffer::snapshot_with_edits` and
`Buffer::fast_forward`, which allow us to move the parsing of the new
base text into the background and then install the new syntax tree
synchronously on the foreground.

The git store uses the low-level APIs `set_snapshot` and `fast_forward`
directly, and manages the head text and index text buffers itself
(garbage-collecting them when they're no longer needed); this enables
adding an `open_staged_diff` API which returns a diff between the
managed index buffer and the managed head buffer (the latter is also
used for the uncommitted diff's base text). Other downstreams don't need
to reuse a base text buffer, and those have been migrated to use the
high-level `set_base_text` API, which now calls `set_snapshot` and
`fast_forward` internally, with a guard to prevent concurrent updates.

Another change worthy of note is that we now always diff the old base
text with the new base text to create `snapshot_with_edits`.

There are also some incidental bug fixes:
- Fixed an issue where a dangling weak unstaged diff could stick around
in the git store forever
- Restored the `IndexMatchesHead` optimization that had become
inoperative in the remote case
- Fixed a crash in the multibuffer due to the handling of
`BufferDiffEvent::LanguageChanged`, which could cause the multibuffer to
have transforms that were inconsistent with the diff base text.

Miguel Raz Guzmán Macedo b1ba025093 Use unstable sorts if deduplicating (#58751)
# Impact

Recent Project picker, `find all references`, the sidebar's
`rebuild_contents` might get a slight speed boost.

# Reasoning

Unstable sort variants

https://doc.rust-lang.org/stable/std/primitive.slice.html#method.sort_unstable
are non-allocating but potentially destructive. Since we're
deduplicating elements anyways, use the unstable variant.

This call will use ipnsort


https://github.com/Voultapher/sort-research-rs/blob/main/writeup/unreasonable/text.md#various-generic-algorithms

I expect the speedups to be at least 30%, though it's highly input

Finn Eitreim 5b71e46f2e outline: Switch the outline search to use fuzzy_nucleo (#56477)
Nucleo tracking issue:
https://github.com/zed-industries/zed/issues/55872

This PR switches the outline picker to use `fuzzy_nucleo`. 

with that I refactored the outline fuzzy picking to take advantage of
nucleo and its multi-atom query support. The previous implementation had
a lot going on specifically to work around the lack of multiple atoms,
basically taking matters into its own hands to accomplish the same goals
within the constraints it had.

Instead of having two lists of candidates that we have to run the query
against, we just run a single query and take advantage of the fact that
nucleo chooses the matches that are the furtherest towards the end of
the haystack to implement the same ancestor/leaf filtering. It retains
the leaf only matching on single atom queries.

Anthony Eid ab913c96c6 helix: Fix paste crash (#58373)
Closes [#58343](<https://github.com/zed-industries/zed/issues/58343>)

This crash happened because Helix paste restored selection using the raw
clipboard text length, but buffer edits normalize CRLF line endings to
LF before inserting. When pasting CRLF text at or near EOF, the restored
selection could extend past the normalized snapshot length and panic in
`MutableSelectionsCollection::select_ranges`. The fix normalizes the
text before measuring it for selection restoration and adds regression
coverage for CRLF paste in Helix mode.

Smit Barmase 6fdd0daaa2 language: Support emitting multiple runnables from a single tree-sitter match (#57276)
Sets up infra for fixing #46881. Follow-up to the approach discussed in
#36802 (comment).

The initial problem: Go table tests weren't being detected reliably in
larger files. The old approach created one tree-sitter match per table
row, which hit the cursor match limit (64) and caused rows to be
silently dropped.

The suggested fix was to use query repetition to capture all rows in a
single match, then post-process in Rust.

But this hit another problem: some captured rows aren't valid runnables
(e.g., when a struct has multiple string fields and the query can't tell
which one is the test name). Tree-sitter predicates can't validate
subsets of captures within a match, that logic needs to happen in Rust.

This PR adds a `RunnableResolver` trait that lets languages post-process
multi-capture matches. When a query uses `@_run_item` to mark item
boundaries, we split the captures into per-item groups and pass them to
the resolver. The resolver can then:

- Pick which `@run` to use: e.g., compare field names against
`t.Run(tc.name, ...)` to find the right string field.
- Return per-item extras: only the captures that correspond to the
chosen `@run`.

No, sadly, the title is not a typo. See

I'll read with joy and popcorn through that root cause analysis.

It makes literally zero sense what happened here, but for some completly

https://github.com/zed-industries/zed/pull/54632.

I have no idea how it happened. It makes literally zero sense. A PR
going into the merge queue should have the same LoC when getting out of
it. GitHub obviously does not check this. GitHub causes extra work with

a5ce6f8dfb Fix freeze when binary content written to open empty file (#53074)
Opening an empty file then writing binary content to it on disk causes a
permanent freeze (not a crash — requires force kill).

`reload_impl` loads raw bytes via `load_bytes` and decodes with
`encoding_rs` but never checks if the content is binary. The existing
binary check in `decode_file_text` only runs on fresh opens, not
reloads. So binary content enters the buffer as lossy UTF-8.

Binary data has almost no newlines, producing a single enormous row. The
wrap map's sync fast path in `flush_edits` checks row count (< 100 rows)
but not line length, so it runs `wrap_line` on a multi-MB single line
synchronously on the main thread via `smol::block_on`. Font shaping
millions of non-ASCII replacement characters blocks the UI thread
indefinitely.

Two fixes, both one-condition guards:
- Null-byte check in `reload_impl` before decoding, same heuristic
(first 8000 bytes) used by `decode_file_text` on fresh opens. Binary
content never enters the buffer.
- Column-length guard (`MAX_SYNC_WRAP_COLUMNS = 10_000`) on the wrap map
sync fast path so absurdly long lines fall through to the async
background path. Defense in depth for any single-line content that's too
long to shape synchronously.

## Test plan
- [ ] Open an empty file in Zed, write binary content to it externally
(e.g. `cp /bin/ls /path/to/open-file`) — should show "Binary files are
not supported" instead of freezing
- [ ] Open a compressed file (zip, gz) that starts empty and gets filled
— same behavior
- [ ] Normal text file reload still works (no regression)
- [ ] Very long single-line text files (>10k columns) don't freeze the
editor

Max Brunsfeld f4de5d9582 Revert "language: Fix slow Tree-sitter parsing" (#54524)
It's currently not valid to limit the syntax highlighting cursor in this
way, because it prevents us from recognizing important patterns like
`(function_item name:(identifier) @function` if the function exceeds the
context length, which is common. We'll need to think harder about
whether there's a different solution the problem of slow queries in the
presence of large parse errors.

Om ChillureandMax Brunsfeld 5ddee8c145 language: Fix slow Tree-sitter parsing (#52674)
#### Context

When tree-sitter parses a file with broken syntax (e.g. a large partial
SQL `VALUES` clause, or any language where a large chunk becomes
invalid), it can produce a single `ERROR` node spanning thousands of
lines. On every render frame, Zed queries this tree for syntax
highlights via `SyntaxMapCaptures`. Previously, only `set_byte_range`
was applied to the query cursor - this limits which captures are
*returned*, but tree-sitter still had to *traverse* the entire ERROR
subtree to find them, causing O(file size) work per frame and making
scrolling/editing visibly laggy.

The fix applies `set_containing_byte_range` to the highlight query
cursor, mirroring what `SyntaxMapMatches` already does for indentation
and bracket queries. This tells tree-sitter to skip subtrees that extend
far beyond the visible window, reducing traversal to the visible range
only.

**Note:** This fix eliminates the main freeze/stall caused by full-tree
traversal. A small amount of lag may still occur on very large broken
files, as tree-sitter still needs to parse the error-recovery structure.
Further improvements would require deeper changes to tree-sitter's query
execution or incremental parsing.


#### Closes #52390

#### How to Review

Small change — focus on
[syntax_map.rs:1119-1123](crates/language/src/syntax_map.rs#L1119) (the
fix) and the `containing_byte_range_for_captures` helper below it.
Compare with the existing `SyntaxMapMatches::new` path (line ~1255)
which uses the same pattern.

Tim VermeulenandConrad Irwin 0cbdde0ca9 editor: Fix autoscroll sometimes obscuring the current row behind a sticky header (#53165)
Fixes an autoscroll bug that sometimes obscures the current row behind a
sticky header.

The bug was caused by `Editor::autoscroll_vertically` using the
`sticky_header_line_count` value that was cached during the previous
render, which isn't necessarily the number of sticky headers that the
scroll target needs, e.g.
- when jumping to a definition
- when pressing the up arrow key when the selection is in the topmost
visible row with `"vertical_scroll_margin": 0`

This fixes that by not caching `sticky_header_line_count` and instead
querying Tree-sitter on the fly to get the number of sticky headers that
the scroll target needs. Performance-wise this seem okay, I measured it
to take less than 200µs on my machine using a very large Rust file (and
there are still some possible ways to optimize this if necessary). In
particular, the pathological huge single-line file case as discussed in
#48450 shouldn't be an issue here because unlike the main sticky header
Tree-sitter query, here we query the outline items that contain a
particular point rather than those that intersect an entire row.

The `ScrollCursorTop` handler is also simplified to use the same shared
function for counting the number of sticky headers, since that action
doesn't rely on autoscroll.

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/ca8bd8681c123b995b495a79d760bc0d88220fd0/crates/editor/src/element.rs#L3820-L3822
and the coupling of `language_aware` with `diagnostics` in
https://github.com/zed-industries/zed/blob/ca8bd8681c123b995b495a79d760bc0d88220fd0/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"

ab3697f163 Extract language_core and grammars crates from language (#52238)
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.

Release Notes:

- N/A

ef282cca24 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

Kai Kozlov a88bcd3714 Fix incorrect rainbow bracket matching in Markdown (#52107)
## Context

Fixes #52022.

Rainbow bracket matching could become incorrect when tree-sitter
returned ambiguous bracket pairs for the same opening delimiter. The
repair path rebuilt pairs using a shared stack across all bracket query
patterns, which let excluded delimiters like Markdown single quotes
interfere with parenthesis matching.

This change scopes that repair logic to each bracket query pattern so
ambiguous matches are rebuilt without mixing unrelated delimiter types.
It also adds a regression test for the Markdown repro from the issue.

## How to Review

058ea457a7 Add size to DiskState to detect file changes (#49436)
## Summary

This fix addresses the cross-platform root cause identified in issue
#38109 where open buffers go stale or empty when external tools write
files.

## The Problem

The buffer's `file_updated()` method was only comparing `mtime` to
determine if a buffer needed to be reloaded. This caused a race
condition when external tools write files using `std::fs::write()`,
which uses `O_TRUNC` and creates a brief window where the file is 0
bytes:

1. Scanner re-stats → sees 0 bytes, mtime T
2. `file_updated()` sees mtime changed → emits `ReloadNeeded`
3. Buffer reloads to empty, stamps `saved_mtime = T`
4. Tool finishes writing → file has content, but mtime is still T (or
same-second granularity)
5. Scanner re-stats → mtime T matches `saved_mtime` → **no reload
triggered**
6. Buffer permanently stuck empty

## The Fix

Release Notes:

- Add the file `size` to `DiskState::Present`, so that even when mtime
stays the same, size changes (0 → N bytes) will trigger a reload. This
is the same fix that was identified in the issue by @lex00.

## Changes

- `crates/language/src/buffer.rs`: Add `size: u64` to
`DiskState::Present`, add `size()` method
- `crates/worktree/src/worktree.rs`: Pass size when constructing File
and DiskState::Present
- `crates/project/src/buffer_store.rs`: Pass size when constructing File
- `crates/project/src/image_store.rs`: Pass size when constructing File
- `crates/copilot/src/copilot.rs`: Update test mock

## Test plan

- [ ] Open a file in Zed
- [ ] Write to that file from an external tool (e.g., `echo "content" >
file`)
- [ ] Verify the buffer updates correctly without needing to reload

Fixes #38109

0a8e423a4a buffer: Reload after undo when file changed while dirty (#51037)
Closes #48697
Supersedes #48698
Related to #38109

## Problem

If you edit a file and an external tool writes to it while you have
unsaved changes, Zed tracks the new file but skips the reload to
preserve your edits. If you then undo everything, the buffer goes back
to clean but still shows the old content. The disk has moved on, but
nothing triggers a reload.

## Fix

In `did_edit()`, when the buffer transitions from dirty to clean, check
if the file's mtime changed while it was dirty. If so, emit
`ReloadNeeded`. Only fires for files that still exist on disk
(`DiskState::Present`).

7 lines in `crates/language/src/buffer.rs`.

### No double reload

`file_updated()` suppresses `ReloadNeeded` when the buffer is dirty
(that's the whole bug). So by the time `did_edit()` fires on
dirty-to-clean, no prior reload was emitted for this file change. The
two paths are mutually exclusive.

## Test plan

- New: `test_dirty_buffer_reloads_after_undo`
- No regression in `test_buffer_is_dirty` or other buffer tests
- All project integration tests pass
- clippy clean

Release Notes:

- Fixed an issue where buffer content could become stale after undoing
edits when an external tool wrote to the file while the buffer was
dirty.

Oliver Azevedo BarnesandMrSubidubi 58eac50e17 editor: Add support for no auto-indent on enter (#47751)
Closes #47550

Changes the `auto_indent` setting from a boolean to an enum with three
modes:

- **`full`** (default): Adjusts indentation based on syntax context when
typing (previous `true` behavior)
- **`preserve_indent`**: Preserves the current line's indentation on new
lines, but doesn't adjust based on syntax
- **`none`**: No automatic indentation - new lines start at column 0
(previous `false` behavior)

This gives users more control over indentation behavior. Previously,
setting `auto_indent: false` would still preserve indentation on new
lines, which was unexpected.

Includes:
- Settings migration from boolean to enum values
- Settings UI dropdown renderer

Release Notes:

- Changed `auto_indent` setting from boolean to enum with `full`,
`preserve_indent`, and `none` options

Marco Mihai Condrache 8044f484ca editor: Optimize TabMap chunks generation (#48378)
Currently, the next chunk is generated by traversing all characters of
the current folded chunk until a tab is found. Since we already have
bitmasks for characters and tabs, we can also propagate the newlines
bitmap from the rope and use it to make this computation O(1) in all

Vitaly Slobodin 82f3eca559 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

`syntax_layers` does some offset conversion that might require getting
some chunks from the rope, which is quite expensive. For detecting
autoclose, we only use the language from those syntax layers, so having
a short path that skips all the conversion should skip some sum_tree
traversals.
   
I'm pretty sure other places would benefit from this as well, but I
haven't searched them yet.

Ichimura TomooandConrad Irwin 7e35e566b3 encoding: Add "reopen with encoding" (#46553)
# Add "Reopen with Encoding" feature (Local/Single user)

## Summary

This PR adds a "Reopen with Encoding" feature to allow users to manually
specify an encoding and reload the active buffer.

This feature allows users to explicitly specify the encoding and reload
the file to resolve garbled text caused by incorrect detection.

## Changes

1.  Added encoding picker logic to `encoding_selector`

- Implemented a modal UI accessible via the command palette, shortcuts,
or by clicking the encoding status in the status bar.
- Allows users to select from a list of supported encodings (Shift JIS,
EUC-JP, UTF-16LE, etc.).

2.  Updated Buffer logic (crates/language)

- Added a `force_encoding_on_next_reload` flag to the Buffer struct.
- Updated the `reload` method to check this flag and apply the following
logic:
- **Non-Unicode (e.g., Shift JIS):** Bypasses heuristics (like BOM
checks) to force the specified encoding.
- **Unicode (e.g., UTF-8):** Performs standard BOM detection. This
ensures that the BOM is correctly handled/consumed when switching back
to UTF-8.

3.  UI / Keymap

- Made the encoding status in the status bar (ActiveBufferEncoding)
clickable.
- Added default keybindings:
  - macOS: cmd-k n
  - Linux/Windows: ctrl-k n
  - Windows: ctrl-k n

## Limitations & Scope

To ensure stability and keep the PR focused, the following scenarios are
intentionally out of scope:

1. **Collaboration and Remote Connections**

- Encoding changes are disabled when collaboration (is_shared) or SSH
remote connections (is_via_remote_server) are active.
- **Reason:** Synchronizing encoding state changes between host/guest or
handling remote reloads involves complex synchronization logic. This PR
focuses on local files only.

`Remote Connection (SSH/WSL)`

/>|

2. Dirty State

- The feature is disabled if the buffer has unsaved changes to prevent
data loss during reload.

src="https://github.com/user-attachments/assets/d170ea1e-9fcb-42e7-aa3e-0555b4a19d86"
/>|

3. Files detected as Binary

Files that worktree detects as "binary" (e.g., UTF-16 files without BOM
containing non-ASCII characters) are not opened in the editor, so this
feature cannot be triggered.
**Future Work**: Fixing this would require modifying crates/worktree
heuristics or exposing a "Force Open as Text" action for InvalidItemView
to trigger. Given the scope and impact, this is deferred to a future PR.

## Test Plan

I verified the feature and BOM handling using the following scenarios:

### Preparation

Used the following test files:

-
[**test_utf8.txt**](https://github.com/user-attachments/files/24548803/test_utf8.txt):
English-only text file. No BOM.
-
[**test_utf8_bom.txt**](https://github.com/user-attachments/files/24548822/test_utf8_bom.txt):
English-only text file. With BOM.
-
[**test_utf8_jp_bom.txt**](https://github.com/user-attachments/files/24548825/test_utf8_jp_bom.txt):
UTF-8 with BOM file containing Japanese characters.
-
[**test_shiftjis_jp.txt**](https://github.com/user-attachments/files/24548827/test_shiftjis_jp.txt):
Shift-JIS file containing Japanese characters (content designed to
trigger misdetection, e.g., using only half-width katakana).

Used an external editor (VS Code or Notepad) for verification.

### Case 1: English-only file behavior

1.  Open an English-only UTF-8 file (test_utf8.txt).
2.  Reopen as Shift JIS.
3.  **Result:**

- Text appearance remains unchanged (since ASCII is compatible).
- Status bar updates to "Shift JIS".

### Case 2: Fixing Mojibake

1. Open a Shift-JIS file (test_shiftjis_jp.txt) that causes detection
failure.
    ※Confirm it opens with mojibake
2.  Select Shift JIS from the status bar selector.
3.  **Result:**

- Mojibake is resolved, and Japanese text is displayed correctly.
- Status bar updates to "Shift JIS".

### Case 3: Unicode file with BOM behavior

1.  Open an English-only UTF-8 with BOM file (test_utf8_bom.txt).
2.  Reopen as `Shift JIS`.
3.  **Result:**

- The BOM bytes are displayed as mojibake at the beginning of the file.
- The rest of the English text is displayed normally (ASCII
compatibility).
- Status bar updates to "Shift JIS".

### Case 4: Non-Unicode file with BOM behavior

1. Open a UTF-8 with BOM file containing Japanese
(test_utf8_jp_bom.txt).
2.  Reopen as Shift JIS.
3.  **Result:**

- The BOM bytes at the start are displayed as mojibake.
- The Japanese text body is displayed as mojibake (UTF-8 bytes
interpreted as Shift JIS).
- Status bar updates to "Shift JIS" (no BOM indicator).

### Case 5: Revert to Unicode

1.  From the state in Case 4 (Shift JIS with mojibake), reopen as UTF-8.
2.  **Result:**

- The BOM mojibake at the start disappears (consumed).
- The text returns to normal.
- Status bar updates to "UTF-8 (BOM)".

### Case 6: External BOM removal (State sync)

1.  Open a UTF-8 with BOM file in Zed (test_utf8_bom.txt).
2. Open the same file in an external editor and save it as UTF-8 (No
BOM).
3.  Refocus Zed.
4.  **Result:**

- Text appearance remains unchanged.
- The (BOM) indicator disappears from the status bar.
- Saving in Zed and checking externally confirms the BOM is gone.

### Case 7: External BOM addition

1. From the state in Case 6 (UTF-8 No BOM), save as UTF-8 with BOM in
the external editor.
2.  Refocus Zed.
3.  **Result:**

- The (BOM) indicator appears in the status bar.
- Saving in Zed and checking externally confirms the BOM is present.

### Case 8: External Encoding Change (Auto-detect sync)

1.  Open an English-only UTF-8 file in Zed (`test_utf8.txt`).
    * *Status bar shows: "UTF-8".*
2. Open the same file in an external editor and save it as **UTF-16LE
with BOM**.
3.  Refocus Zed.
4.  **Result:**
    * The text remains readable (no mojibake).
* **Status bar automatically updates to "UTF-16LE (BOM)".** (Verifies
that `buffer.encoding` is correctly updated during reload).

Release Notes:

- Added "Reopen with Encoding" feature (currently supported for local
files).

a3174dab48 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
