## Context / Related PRs This PR is the third part of the encoding
support improvements, following:
- #44819: Introduced initial legacy encoding support (Shift-JIS, etc.).
- #45243: Fixed UTF-16 saving behavior and improved binary detection.

## Summary
This PR implements a status bar item that displays the character
encoding of the active buffer (e.g., `UTF-8`, `Shift_JIS`). It provides
visibility into the file's encoding and indicates the presence of a Byte
Order Mark (BOM).

## Features
- **Encoding Indicator**: Displays the encoding name in the status bar.
- **BOM Support**: Appends `(BOM)` to the encoding name if a BOM is
detected (e.g., `UTF-8 (BOM)`).
- **Configuration**: The active_encoding_button setting in status_bar
accepts "enabled", "disabled", or "non_utf8". The default is "non_utf8",
which displays the indicator for all encodings except standard UTF-8
(without BOM).
- **Settings UI**: Provides a dropdown menu in the Settings UI to
control this behavior.
- **Documentation**: Updated `configuring-zed.md` and
`visual-customization.md`.

## Implementation Details
- Created `ActiveBufferEncoding` component in
`crates/encoding_selector`.
- The click handler for the button is currently a **no-op**.
Implementing the functionality to reopen files with a specific encoding
has potential implications for real-time collaboration (e.g., syncing
buffer interpretation across peers). Therefore, this PR focuses strictly
on the visualization and configuration aspects to keep the scope simple
and focused.
- Updated schema and default settings to include
`active_encoding_button`.

/>


## Configuration
To hide the button, add the following to `settings.json`:
```json
"status_bar": {
  "active_encoding_button": "disabled"
}
```

- **enabled**: Always show the encoding.
- **disabled**: Never show the encoding.
- **non_utf8**: Shows for non-UTF-8 encodings and UTF-8 with BOM. Only
hides for standard UTF-8 (Default).

src="https://github.com/user-attachments/assets/7f4f4938-3320-4d21-852c-53ee886d9a44"
/>

## Heuristic Limitations:
The underlying detection logic (implemented in #44819 and #45243)
prioritizes UTF-8 opening performance and does not guarantee perfect
detection for all encodings. We consider this margin of error
acceptable, similar to the behavior seen in VS Code. A future "Reopen
with Encoding" feature would serve as the primary fallback for any
misdetections.

Release Notes:

- Added a status bar item to display the active file's character encoding (e.g. `UTF-16`). This shows for non-utf8 files by default and can be configured with `{"status_bar":{"active_encoding_button":"disabled|enabled|non_utf8"}}`

I was seeing some surprising un-coalesced edits in the edit history when
looking at captured examples. I realized that we were only coalescing
based on the *ends* of edit ranges, but I think we want to combine hunks
where there are 8 or less unchanged lines in between changes. This PR
implements that.

Per LSP spec, when receiving `workspace/diagnostic/refresh`, clients
should refresh all pulled diagnostics including both workspace and
document diagnostics[^1]. Previously, only workspace diagnostics were
refreshed.

[^1]:
https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#diagnostic_refresh

This adds `pull_document_diagnostics_for_server()`, which refreshes
`textDocument/diagnostic` for all open buffers associated with the
given language server.

Closes #ISSUE

Release Notes:

- When handling `workspace/diagnostic/refresh`, Zed now also sends new
`textDocument/diagnostic` requests for open files, aligning with the LSP
specification.

Now when the agent reads images (which the tool now explicitly
advertises to agents that it is capable of; previously the tool said it
could only read text even though it can actually read images), we see
them in the thread, and also they are auto-expanded by default so you
can see them when scrolling through:

<img width="725" height="1019" alt="Screenshot 2026-01-06 at 2 57 11 PM"
src="https://github.com/user-attachments/assets/5c908bad-48f2-46c2-afaa-7f189a178e05"
/>

This also adds a visual regression test that verifies images render
correctly in the agent thread view.

Unlike our previous visual tests, this one only renders the agent panel,
not the entire Zed window.

The "screenshot" it generates (rendered to a Metal texture) is from
completely mocked/simulated data structures, and looks like this:

<img width="546" height="984" alt="Screenshot 2026-01-06 at 2 54 41 PM"
src="https://github.com/user-attachments/assets/89a0921f-59e9-4dfe-94b2-4c3b625a851b"
/>

## Changes

- **New visual test**: `agent_thread_with_image` renders an
`AcpThreadView` containing a tool call with image content (the Zed app
icon)
- **Test infrastructure**: Added `StubAgentServer` helper and required
feature flags for visual testing
- **Test-support API**: Added `expand_tool_call()` method to
`AcpThreadView` to allow expanding tool calls for visual testing
- **Baseline screenshot**: Included baseline image showing the Zed logo
rendered in a tool call output

## How to run

```bash
# Run the visual tests
cargo run -p zed --bin visual_test_runner --features visual-tests

# Update baselines if UI intentionally changed  
UPDATE_BASELINE=1 cargo run -p zed --bin visual_test_runner --features visual-tests
```

Adds various useful things to the repl inspired by ipynb and the julia
vscode extension which can be best seen with this video:


https://github.com/user-attachments/assets/6589715e-3783-456c-8f4b-e2d5a1c4090d

To summarize:

## Inline outputs
Added small, single-line outputs displayed inline at the end of the code
line instead of in a separate block. This provides a cleaner, more
compact view for simple results like numbers or short strings. This
occurs for execution views who only output a single mimetype/plain OR
output nothing, otherwise the default behavior of creating a block will
occur.

It looks like this: 
<img width="258" height="35" alt="image"
src="https://github.com/user-attachments/assets/ccdeca3f-c3b7-4387-a4de-53d8b9a25132"
/>
or with a Output

src="https://github.com/user-attachments/assets/0b4effc9-1bd7-4e8c-802f-8733cdcc77d1"
/>
This was inspired by julia vscode extension, but now it can be used with
any replanguage! Hooray!


<img width="524" height="450" alt="image"
src="https://github.com/user-attachments/assets/a3551e51-f5f7-4d3e-994a-213c9d2f948c"
/>

It saves lots of space compared to the ugly and distracting:
<img width="531" height="546" alt="image"
src="https://github.com/user-attachments/assets/7cf65bae-8ec1-4279-ab19-f0d4ec4052a2"
/>


## Gutters and execution numbers
Added gutters + execution number to display exactly what was executed.
The gutter highlighting is useful for when selecting multiple cells
manually to run, but you dont remember which ones

Ran at different times:
<img width="257" height="58" alt="image"
src="https://github.com/user-attachments/assets/6002ab16-156a-4598-9964-5a6b188e989c"

src="https://github.com/user-attachments/assets/2690ea35-2bd3-4207-b039-6c0f98dad6e4"
/>

The execution number is useful in the same way that a normal jupyter
notebook execution number is useful.

If a gutter-region does not have a block assigned to it, when you edit
the text in the gutter region, the gutter will disappear, which is
useful for telling when you have modified your code, but does not delete
useful experiment results in blocks:

<img width="280" height="38" alt="image"

src="https://github.com/user-attachments/assets/f306c364-1c92-44bd-9050-ecce1b7822a0"
/>
 
## Skip empty line
This is a minor fix which is intended to make lab workflow less tedious.
Currently when you execute on an empty line (which might be there for
formatting purposes) nothing will occur. This PR adds the ability to,
when executing from an empty line, skip ahead the range of inclusion
until you reach actual code, and then execute.

Before:
```
code //run execute
//empty space, so you have to move your cursor down or use arrow key
code //run execute
code //run execute
```
After:
```
code //run execute
//empty space, you can now run execute on it and it will include the next line of code
//empty space
code //automatically executed
code //run execute
```

Currently the only piece of tested code is related to this, i still have
to write tests for the gutter annotation api i added and all of the
gutter + inline related code. Also still have to add more config for
this stuff.

@rgbkrk would appreciate a review :D

Closes #22678

Current tree sitter configuration for the outline was not working
correctly since the rule required a strict order, firstly
storage_class_specifier then type_qualifier. This resulted in a failure
to recognize types such as "constexpr int", "const double", etc. This PR
proposes a solution with diagnostic capture of type and storage
qualifiers which ensures full context capture and works well with C++.

This fixes the auto-update failure by ensuring cargo-bundle picks 'zed'
as the first binary.

**Problem:** `cargo metadata` returns binaries alphabetically, so
`visual_test_runner` was coming before `zed`. When cargo-bundle looks
for the first binary to bundle (without `--bin`), it was picking
`visual_test_runner` - which doesn't exist in release builds because it
requires the `visual-tests` feature.

The previous fix (#46163) added `--bin zed` to explicitly select the
binary, but this caused cargo-bundle to use the binary name ('zed')
instead of the bundle metadata name ('Zed Nightly'), breaking
auto-updates.

**Fix:** Rename the binary to `zed_visual_test_runner` so it comes after
`zed` alphabetically. This restores the original bundle script behavior
that has worked for years.

Also reverts the `--bin zed` workaround from #46163.

- Fixed an issue on macOS where audio playback would become temporarily

The visual_test_runner binary (added in #45259) has `required-features =
["visual-tests"]`, so it doesn't get built in release builds. However,
`cargo bundle` was trying to bundle all binaries defined in the zed
crate's Cargo.toml, causing it to fail when visual_test_runner doesn't
exist.

Adding `--bin zed` tells cargo bundle to only bundle the main zed
binary.

**Note:** The `cli` binary is unaffected by this change - it's a
separate package (`crates/cli`) that's built separately via `cargo build
--package cli` and manually copied into the app bundle afterward (line
337). It was never part of `cargo bundle`'s scope.

Previously, `detail` was not included in resolvable properties, which
prevented LSP-compliant servers from lazily resolving it.

In relation to this, I also investigated vtsls issues:
- https://github.com/yioneko/vtsls/issues/213
- https://github.com/zed-industries/zed/pull/21521

My conclusion is that regardless of whether Zed registers `detail` in
resolvable properties, vtsls always lazily resolves `detail`. However, I
understand that Zed's `resolve_completions` has been improved to handle
such "misbehaving" servers gracefully already, so I expect that adding
`detail` to resolvable properties will not cause any issues.

In fact, since Zed can lazy update all properties of completion items,
it might be appropriate to include all properties as resolvable except
for `label` (which is explicitly tested for consistency) and `data`
(which is used for resolution itself once).
However, since I'm uncertain if this is entirely correct, this commit
only adds `detail` to resolvable properties, as it was required to be
supported by LSP clients up to version 3.16.

When the UI font size changes, the settings window's scrollbar would
break because list item measurements were cached and not invalidated.

We're using `ListState.measure_all()` to pre-measure all items for an
accurate scrollbar. When font size changes, these cached measurements
become stale but weren't being refreshed.

This commit fixes the issue by calling `ListState.measure_all()` when
settings change, ensuring items are re-measured on the next layout
without affecting scroll position.
