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).

Closes#41422
This completely broke line numbering as described in the linked issue
and scrolling up does not have the correct numbers any more.
Release Notes:
- NOTE: The `relative_line_numbers` change
(https://github.com/zed-industries/zed/pull/39268) was reverted and did
not make the release cut!
**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 an discussed in

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`.

This shrinks it from roughly a ~kilobyte to 8 byte, removing a bunch of
memmoves emitted by the compiler. Also `Arc`'s it instead of boxing as
we do clone it a couple times here and there, making that also a fair
bit cheaper

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

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.

## 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

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.

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

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.

Closes#36247
Fix a panic when padding inlay hints if the last character is a
multi-byte character. Regressed in

Release Notes:
- Fixed a crash that could occur when an inlay hint ended with `...`.
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#15542Closeszed-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.
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.

This gets rid of the need to pass context to all cursor functions. In
practice context is always immutable when interacting with cursors.
A nicety of this is in the follow-up PR we will be able to implement
Iterator for all Cursors/filter cursors (hell, we may be able to get rid
of filter cursor altogether, as it is just a custom `filter` impl on
iterator trait).
Release Notes:

This PR aims to improve the minimap performace. This is primarily
achieved by disabling/removing stuff that is not shown in the minimal as
well as by assuring the display map is not updated during minimap
prepaint.
This should already be much better in parts, as the block map as well as
the fold map will be less frequently updated due to the minimap
prepainting (optimally, they should never be, but I think we're not
quite there yet).
For this, I had to remove block rendering support for the minimap, which
is not as bad as it sounds: Practically, we were currently not rendering
most blocks anyway, there were issues due to this (e.g. scrolling any
visible block offscreen in the main editor causes scroll jumps
currently) and in the long run, the minimap will most likely need its
own block map or a different approach anyway. The existing
implementation caused resizes to occur very frequently for practically
no benefit. Can pull this out into a separate PR if requested, most
likely makes the other changes here easier to discuss.
This is WIP as we are still hitting some code path here we definitely
should not be hitting. E.g. there seems to be a rerender roughly every
second if the window is unfocused but visible which does not happen when
the minimap is disabled.
While this primarily focuses on the minimap, it also touches a few other
small parts not related to the minimap where I noticed we were doing too
much stuff during prepaint. Happy for any feedback there aswell.
Putting this up here already so we have a place to discuss the changes
early if needed.
Release Notes:
- Improved performance with the minimap enabled.
- Fixed an issue where interacting with blocks in the editor would
sometimes not properly work with the minimap enabled.

Also adds the code to support `textDocument/colorPresentation`
counterpart that serves as a resolve mechanism for the document colors.
The resolve itself is not run though, and the editor does not
accommodate color presentations in the editor yet — until a well
described use case is provided.
Use `lsp_document_colors` editor settings to alter the presentation and
turn the feature off.
Release Notes:
- Start showing inline previews for LSP document colors
- [x] foreground highlights

Closes#31919
Release Notes:
- Fixed a panic that could sometimes occur when the agent panel was too
narrow and contained context included via `@`.
