I was looking at the rope implementation and some of the existing bugs
that crash in there, and I ran cargo-mutants to inspect test coverage. I
was motivated by bugs like
https://github.com/zed-industries/zed/issues/38556 but this doesn't fix
it and the bug may well be at a higher layer.
This PR adds coverage for a few functions that aren't tested today. I
didn't find any actual bugs yet.
I can see this tree is pretty sparse on docstrings so if you think these
are too verbose I can take them out or drop the whole PR.

When running flycheck, I've noticed that scrolling starts to lag:
https://github.com/user-attachments/assets/b0bef0a3-ccbd-479d-a385-273398086d38
When checking the trace, it is notable that project panel updates its
entire tree multiple times during flycheck:

Turns out, `target/debug` directory is loaded by Zed (presumably,
reported by langserver as there are sources generated by bindgen and
proto that need to be loaded), and `target/debug/build` directory
received multiple events of a `None` kind for Zed, which trigger the
rescans.
Rework the logic to omit the `None`-kind events in Zed, and to avoid
excessive repo updates if not needed.
Release Notes:
- Improved worktree FS event emits in gitignored directories

Follow-up: https://github.com/zed-industries/zed/pull/38590
**Note**: this PR contains changes from the [previous
PR](https://github.com/zed-industries/zed/pull/38590), when that PR gets
merged we should see the real changes.
This PR fixes 4 things in order to make:
1. Add html/markdown minifier to remove all the **\t** and **\n**
characters. This is needed as you cannot create new lines with markdown
by just adding an enter to the source file.
2. The event Event::HTML only contained a chunk of the real html for
multiline HTML code. I fixed this by storing the currently watched HTML
inside a buffer and at the end we parse it into the right elements.
Instead of trying to parse a chunck into multiple elements which would
always fail before.
3. Add support for html tables.
4. Fixed panic that occured when table does not have an header.
I also decided to keep the html minifier inside Zed, because making it a
dependency for just a few 100 lines seems to be an overkill. The
original crate had a few cve in their dependencies, so figured this
would be the best.
**Html table support**

Release Notes:
- Markdown: Added support for html tables
## Problem
When splitting a terminal pane, the new pane opens in the root directory
(`/`) instead of preserving the current working directory of the
original terminal.
For example, when working in `/Users/modestnerd/Developer/Projects/zed`
(my pc) and splitting the terminal pane, the new pane would open in `/`
instead of staying in the current directory.
## Solution
Restructured the fallback logic in
`new_pane_with_cloned_active_terminal` (terminal_panel.rs:452-456) to
ensure `default_working_directory(workspace, cx)` is called as a
fallback even when a terminal view exists but its `working_directory()`
returns `None`.
The fix changes the nested `and_then` to use `or_else` for the fallback,
ensuring the working directory is always properly resolved before
entering the async block.
Release Notes:
- Fixed terminal split pane opening in wrong directory instead of
preserving the current working directory
Fixes a `--release`-only bug in feature-flagged agents where the feature
flag isn't picked up in some situations (unless there was a settings
change to go with it - due to an early return when settings didn't
change).
Release Notes:
- N/A
If we get a `cwd` from ACP (because e.g. `codex-acp` is driving the
terminal rather than our own PTY) then use that to display the `cwd` of
the terminal process.
Release Notes:
- N/A
This only affects `codex-acp` for now.
Not using the PTY in display-only terminals means they don't display the
login prompt (or spurious `%`s) at the end of terminal output
renderings.
Release Notes:
- N/A
The ordering of path-based excerpts in multibuffers regressed with
#38744, because we changed the `path` field of `PathKey` to be a string
(from `std::path::Path`) and used the derived `Ord` implementation,
which doesn't agree with the path-based order of worktree traversals.
This PR fixes that by using `RelPath` for `PathKey`. Instead of using
`File::full_path`, which can be absolute, we always use `File::path` and
distinguish different worktrees using their ID.

This fixes an issue where the outline modal would not work in editors
that had no explicit workspace attached to them.
Release Notes:
- Enabled the outline modal to work in channel notes.
This is the first step to allowing users to type into a numeric stepper
to set its value. This PR makes the numeric stepper take in a generic
type `T` where T: `NumericStepperType`
```rust
pub trait NumericStepperType:
Display
+ Add<Output = Self>
+ Sub<Output = Self>
+ Copy
+ Clone
+ Sized
+ PartialOrd
+ FromStr
+ 'static
{
fn default_format(value: &Self) -> String {
format!("{}", value)
}
fn default_step() -> Self;
fn large_step() -> Self;
fn small_step() -> Self;
fn min_value() -> Self;
fn max_value() -> Self;
}
```
This allows setting of step sizes and min/max values as well as making
the component easier to use.

This PR introduces the `agent_buffer_font_size` setting and renames
`agent_font_size` to `agent_ui_font_size`. This allows whoever wants
`buffer_font_size` and `agent_buffer_font_size` to match, as well as
folks who want a slightly smaller size only in the agent panel (which...
also looks just better by default!).
Release Notes:
- agent: Introduced the `agent_buffer_font_size` setting and renamed
`agent_font_size` to `agent_ui_font_size`, allowing for granular buffer
font size control in the agent panel vs. regular editors.
This PR fixes the JSON schema for the `ExtensionCapabilityContent`.
Having the nested structs in the variants caused the `kind` property to
not be generated properly. Inlining the fields into the variants fixes
this.

This PR adds the ability to control the capabilities granted to
extensions by the extension host via the new
`granted_extension_capabilities` setting.
This setting is a list of the capabilities granted to any extension
running in Zed.
The currently available capabilities are:
- `process:exec` - Grants extensions the ability to invoke commands
using
[`zed_extension_api::process::Command`](https://docs.rs/zed_extension_api/latest/zed_extension_api/process/struct.Command.html)
- `download_file` - Grants extensions the ability to download files
using
[`zed_extension_api::download_file`](https://docs.rs/zed_extension_api/latest/zed_extension_api/fn.download_file.html)
- `npm:install` - Grants extensions the ability to install npm packages
using
[`zed_extension_api::npm_install_package`](https://docs.rs/zed_extension_api/latest/zed_extension_api/fn.npm_install_package.html)
Each of these capabilities has parameters that can be used to customize
the permissions.
For instance, to only allow downloads from GitHub, the `download_file`
capability can specify an allowed `host`:
```json
[
{ "kind": "download_file", "host": "github.com", "path": ["**"] }
]
```
The same capability can also be granted multiple times with different
parameters to build up an allowlist:
```json
[
{ "kind": "download_file", "host": "github.com", "path": ["**"] },
{ "kind": "download_file", "host": "gitlab.com", "path": ["**"] }
]
```
When an extension is not granted a capability, the associated extension
APIs protected by that capability will fail.
For instance, trying to use `zed_extension_api::download_file` when the
`download_file` capability is not granted will result in an error that
will be surfaced by the extension:
```
Language server phpactor:
from extension "PHP" version 0.4.3: failed to download file: capability for download_file https://github.com/phpactor/phpactor/releases/download/2025.07.25.0/phpactor.phar is not granted by the extension host
```
Release Notes:
- Added a `granted_extension_capabilities` setting to control the
capabilities granted to extensions.
Closes#39308

These changes fix an issue with vim's visual block mode when soft
wrapping is enabled. In this situation, if one was to move the cursor
either up or down, the selection would be updated to include visual
(wrapped) rows, instead of only the buffer rows. For example, take the
following contents:
```
1 | And here's a very long line that is wrapping
at this exact point.
2 | And another very long line that is will also
wrap at this exact point.
```
If one was to place the cursor at the start of the first line, character
`A`, trigger visual block mode with `ctrl-v` and then move down one line
with `j`, the selection would end up as (with [X] representing the
selected characters):
```
1 | [A]nd here's a very long line that is wrapping
[a]t this exact point.
2 | [A]nd another very long line that is will also
wrap at this exact point.
```
Instead of the expected:
```
1 | [A]nd here's a very long line that is wrapping
at this exact point.
2 | [A]nd another very long line that is will also
wrap at this exact point.
```
With the changes in this commit, `Vim.visual_block_motion` will now
leverage buffer rows in order to navigate to the next or previous row.
Release Notes:
- Fixed handling of soft wrapped lines in vim's visual block mode
This improves the design of the profile picker a bit by making every
item on it have the same height; it also makes it more consistent with
the model selector.

I'm not sure about the exact conditions for reproducing this issue, but
whenever I build Zed locally and have it open a single-file worktree on
launch, the rust-analyzer language server fails to start up because Zed
attempts to run `rust-analyzer --help` on a path that is not a
directory. This fixes that by running the command on the parent path in
the case of a single-file worktree.
Release Notes:
- Fixed rust-analyzer startup issue in single-file worktrees
Now we use GitHub Releases to detect when there's a new version of
codex-acp out, and we notify the user in the same way we do for the
other external agents.
This also moves `github_download.rs` out of the `languages` crate and
into `http_client`, because now we're not just using it for language
servers anymore, we're also using it for external agents.

Currently most icon theme extensions already support file types like
stories.tsx and stories.svelte. However within Zed itself these file
type overrides are not supported yet. This change adds support for those
Release Notes:
- Added support for icons on file extensions such as stories.tsx and
stories.svelte
This removes a long-standing thing we've done, which is send a `DidSave`
notification to the language server for the clean parts of a
multi-buffer. However, it seems like the intent of that notification is
to tell the language server to reload the file from disk.
As we didn't actually write those files to disk, it seems clearer to not
send this notification; and just remove this whole code-path.
Release Notes:
- Fixed a race where autosave in a multibuffer could cause unsaved
buffers to appear saved
Codex needs (and future projects are anticipated to need as well) a
concept of display-only terminals. This refactors terminals to decouple
the PTY part from the display part, so that we can render terminal
changes based on a series of events - regardless of whether they're
being driven from a PTY inside Zed or from an outside source (e.g.
`codex-acp`).
Release Notes:
- N/A
This was added for Codex, but had undesirable consequences for Claude
Code (on Nightly, never made it to Preview). We're going to address this
in `codex-acp` instead.
