Lukas Wirth 8f8a92ccf0 editor: Reduce amount of sumtree traversals in header_and_footer_blocks (#43709)
Introduces new "mapping point cursors" for the different display map
layers allowing one to map multiple points in increasing order more
efficiently than using the one shot operations.

This is used in the `BlockMap::sync` for `header_and_footer_blocks`
which spends a significant time in sumtree traversal due to repeatedly
transforming points between the different layers. This effectively turns
the complexity of those operations from quadratic in the number of
excerpts to linear, as we only go through the respective sumtrees once
instead of restarting from the start over and over again.

Release Notes:

- Improved performance for editors of large multibuffers with many
different files

Lukas Wirth 8e04706c4d editor: Fix panic in wrap_map (#43650)

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.

Lukas Wirth c98b2d6944 multi_buffer: Typed MultiBufferOffset (#42707)
This PR introduces a new `MultiBufferOffset` new type wrapping size. The
goal of this is to make it clear at the type level when we are
interacting with offsets of a multi buffer versus offsets of a language
/ text buffer. This improves readability of things quite a bit by making
it clear what kind of offsets one is working with while also reducing
accidental bugs by using the wrong kin of offset for the wrong API.

This PR also uncovered two minor bugs due to that.

Does not yet introduce the MultiBufferPoint equivalent, that is for a
follow up PR.

Thomas Heartman fb410ab3ae Support relative line number on wrapped lines (rework) (#41805)
## Add relative line numbers on wrapped lines, take 2

This is a rework of https://github.com/zed-industries/zed/pull/39268
that excludes
https://github.com/zed-industries/zed/pull/39268/commits/e7096d27a6463f6eb7c2a821637c5773b2460c10.
This commit introduced some line number rendering issues as described in
https://github.com/zed-industries/zed/issues/41422.

While @ConradIrwin suggested we try to pass in the buffer rows from the
calling method instead of the snapshot, that
appears to have had unintended consequences and I don't think the two
calculations were intended to do the same thing. Hence, this PR has
removed those changes.

This PR also includes the migration fix originally done by @MrSubidubi
in https://github.com/zed-industries/zed/pull/41351.

## Original PR description and release notes.

**Problem:** Current relative line numbering creates a mismatch with
vim-style navigation when soft wrap is enabled. Users must mentally
calculate whether target lines are wrapped segments or logical lines,
making `<n>j/k` navigation unreliable and cognitively demanding.

**How things work today:**
- Real line navigation (`j/k` moves by logical lines): Requires
determining if visible lines are wrapped segments before jumping. Can't
jump to wrapped lines directly.
- Display line navigation (`j/k` moves by display rows): Line numbers
don't correspond to actual row distances for multi-line jumps.

**Proposed solution:** Count and number each display line (including
wrapped segments) for relative numbering. This creates direct
visual-to-navigational correspondence, where the relative number shown
always matches the `<n>j/k` distance needed.

**Benefits:**
- Eliminates mental overhead of distinguishing wrapped vs. logical lines
- Makes relative line numbers consistently actionable regardless of wrap
state
- Preserves intuitive "what you see is what you navigate" principle
- Maintains vim workflow efficiency in narrow window scenarios

Also explained and discussed in
https://github.com/zed-industries/zed/discussions/25733.

Release Notes:

- Added support for counting wrapped lines as relative lines and for
displaying line numbers for wrapped segments. Changes
`relative_line_numbers` from a boolean to an enum: `enabled`,
`disabled`, or `wrapped`.

Lukas Wirth ac3b232dda Reduce amount of foreground tasks spawned on multibuffer/editor updates (#41479)
When doing a project wide search in zed on windows for `hang`, zed
starts to freeze for a couple seconds ultimately starting to error with
`Not enough quota is available to process this command.` when
dispatching windows messages. The cause for this is that we simply
overload the windows message pump due to the sheer amount of foreground
tasks we spawn when we populate the project search.

This PR is an attempt at reducing this.

Release Notes:

- Reduced hangs and stutters in large project file searches

Anthony Eid d44437d543 display map: Fix left shift debug panic (#38656)
Closes https://github.com/zed-industries/zed/issues/38558

The bug occurred because TabStopCursor chunk_position.1 is bounded
between 0 and 128. The fix for this was changing the bound to 0 and 127.

This also allowed me to simplify some of the tab stop cursor code to be
a bit faster (less branches and unbounded shifts).

ed5b9a4705 Rework inlay hints system (#40183)
Closes https://github.com/zed-industries/zed/issues/40047
Closes https://github.com/zed-industries/zed/issues/24798
Closes https://github.com/zed-industries/zed/issues/24788

Before, each editor, even if it's the same buffer split in 2, was
querying for inlay hints separately, and storing the whole inlay hint
twice, in `Editor`'s `display_map` and its `inlay_hint_cache` fields.

Now, instead of `inlay_hint_cache`, each editor maintains a minimal set
of metadata (which area was queried by what task) instead, and all LSP
inlay hint data had been moved into `LspStore`, both local and remote
flavors store the data.
This allows Zed, as long as a buffer is open, to reuse the inlay hint
data similar to how document colors and code lens are now stored and
reused.

Unlike other reused LSP data, inlay hints data is the first one that's
possible to query by document ranges and previous version had issue with
caching and invalidating such ranges already queried for.
The new version re-approaches this by chunking the file into row ranges,
which are queried based on the editors' visible area.

Among the corresponding refactoring, one notable difference in inlays
display are multi buffers: buffers in them are not
[registered](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_didOpen)
in the language server until a caret/selection is placed inside their
excerpts inside the multi buffer.

New inlays code does not query language servers for unregistered
buffers, as servers usually respond with empty responses or errors in
such cases.

Release Notes:

- Reworked inlay hints to be less error-prone

Vinicius da Motta f9a2724a8b Remove empty line when collapsing diagnostics (#39459)
Closes #39028

Fixed empty lines appearing when collapsing files with diagnostic
messages in the diagnostics panel.

Added a flag to track when processing a `FoldedBuffer` and skip
`Near/Below` blocks (diagnostic messages) that immediately follow it.
This prevents diagnostics from rendering as empty lines when their file
is collapsed.

Lukas Wirth e1b57f00a0 sum_tree: Reduce Cursor size for contextless summary types (#38776)
This reduces the size of cursor by a usize when the summary does not
require a context making Cursor usages and constructions slightly more
efficient.

This change is a bit annoying though, as Rust has no means of
specializing, so this uses a `ContextlessSummary` trait with a blanket
impl while turning the `Context` into a GAT `Context<'a>`. This means
`Summary` implies are a bit more verbose now while contextless ones are
slimmer. It does come with the downside that the lifetime in the GAT is
always considered invariant, so some lifetime splitting occurred due to
that.

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

Finn Evers 6441099a67 gpui: Fix blending of colors in HighlightStyle::highlight (#37666)
Whilst looking into adding support for RainbowBrackes, we stumbled upon
this: Whereas for all properties during this blending, we take the value
of `other` if it is set, for the color we actually take `self.color`
instead of `other.color` if `self.color` is at full opacity.
`Hsla::blend` returns the latter color if it is at full opacity, which
seems wrong for this case. Hence, this PR swaps these.

Will not merge before the next release, to ensure that we don't break
something somewhere unexpected.

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.

Conrad Irwin bd61eb0889 Use IBM Plex Sans / Lilex (#36084)
The Zed Plex fonts were found to violate the OFL by using the word Plex
in the name.

Lilex has better ligatures and box-drawing characters than Zed Plex
Mono, but Zed Plex Sans should be identical
to IBM Plex Sans.

Closes #15542
Closes zed-industries/zed-fonts#31

Release Notes:

- The "Zed Plex Sans" and "Zed Plex Mono" fonts have been replaced with
"IBM Plex Sans" and "Lilex". The old names still work for backward
compatibility. Other than fixing line-drawing characters, and improving
the ligatures, there should be little visual change as the fonts are all
of the same family.
- Introduced ".ZedSans" and ".ZedMono" as aliases to allow us to easily
change the default fonts in the future. These currently default to "IBM
Plex Sans" and "Lilex" respectively.

Piotr Osiewicz 07e3d53d58 sum_tree: Do not implement Dimension on tuples, use new Dimensions wrapper instead (#35482)
This is a bit of a readability improvement IMHO; I often find myself
confused when dealing when dimension pairs, as there's no easy way to
jump to the implementation of a dimension for tuples to remind myself
for the n-th time how exactly that impl works. Now it should be possible
to jump directly to that impl.

Another bonus is that Dimension supports 3-ary tuples as well - by using
a () as a default value of a 3rd dimension.
