Implements a specialized constructor `LanguageName::new_static` for
`&'static str` which reduces allocations.
`LanguageName::new` always backs the underlying `SharedString` with an
owned `Arc<str>` even when a `&'static str` is passed. This makes us
allocate each time we create a new `LanguageName` no matter what.
Creating a specialized constructor for `&'static str` allows us to
essentially construct them for free.
Additional change:
Encourages using explicit constructors to avoid needless allocations.
Currently there were no instances of this trait being called where the
lifetime was not `'static` saving another 48 locations of allocation.
```rust
impl<'a> From<&'a str> for LanguageName {
fn from(str: &'a str) -> Self {
Self(SharedString::new(str))
}
}
// to
impl From<&'static str> for LanguageName {
fn from(str: &'static str) -> Self {
Self(SharedString::new_static(str))
}
}
```

This mostly affects Channel Notes, but due to a change in
https://github.com/zed-industries/zed/pull/43921 we were
short-circuiting before opening links.
I moved the workspace checks back to right before we need them so that
we still follow the same control flow as usual for these editors.

## Summary
1. Split editor references to avoid borrow conflicts in event handlers
2. Check
[has_mouse_context_menu()](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html)
state directly in tooltip conditional instead of caching stale value
3. Restructured context menu deployment to ensure proper sequencing:
hide popover → build menu → deploy menu → notify for re-render

Addresses a regression introduced by
https://github.com/zed-industries/zed/pull/44021 that caused @mentions
and slash commands to stop working if you set
`show_completions_on_input: false` in your settings.
In this case, we should always show these menus, otherwise the features
won't work at all.
Release Notes:

- Replace `gpui::styled::Styled.font_family()` calls with
`gpui::styled::Styled.font()` when laying out inline diagnostics and
inline blame, to ensure that the font's features are also used, and
not just the font feature.
- Update both `editor::hover_popover::hover_markdown_style` and
`editor::hover_popover::diagnostics_markdown_style` to ensure that
both the UI and Buffer font features are used in both markdown and
diagnostics popover.
Closes#44209
Release Notes:
- Fixed font feature application for inline git blame, inline
diagnostics, markdown popovers and diagnostics popovers
Follow up to https://github.com/zed-industries/zed/pull/44162 where my
strategy for not displaying the indent guides only in the commit message
was wrong given I ended up... disabling indent guides for all the
buffers. This PR adds a new method to the editor where we can disable it
for a specific buffer ID following the pattern of
`disable_header_for_buffer`.

Closes#40757
## Summary
This PR addresses an issue where Zed incorrectly adjusts the indentation
of Markdown lists when inserting text using multiple cursors. Currently:
- Editing individual lines with a single cursor behaves correctly (no
unwanted indentation changes).
- Using multiple cursors, Zed automatically adjusts the indentation,
unlike VS Code, which preserves the existing formatting.
## Tasks
- [x] Implement a new test to verify correct Markdown indentation
behavior with multiple cursors.
- [x] Apply the fix to prevent Zed from adjusting indentation when
inserting text on multiple cursors.
------------------------
Release Notes:
- Fixed an issue where inserting text with multiple cursors inside a
nested Markdown list would cause it to lose its indentation.

The registration ID responsible for generating each diagnostic is now
tracked. This allows us to replace only the diagnostics from the same
registration ID when a pull diagnostics report is applied.
Additionally, various deficiencies in our support for pull diagnostics
have been fixed:
- Document pulls are issued for all open buffers, not just the edited
one. A shorter debounce is used for the edited buffer. Workspace
diagnostics are also now ignored for open buffers.
- Tracking of `lastResultId` is improved.
- Stored pull diagnostics are discarded when the corresponding buffer is
closed.
Release Notes:
- Improved compatibility with language servers that use the "pull
diagnostics" feature of Language Server Protocol.

#42441 moved the commit message out of the multi-buffer editor into its
own header element which looks nicer, but unfortunately can make the
view become unusable when the commit message is too long since it
doesn't scroll with the diff.
This PR maintains the metadata in its own element, but moves the commit
message back to the editor so the user can scroll past it. This does
mean that we lose markdown rendering for now, but we think this is a
good solution for the moment.

Closes#43408
Previously, we checked the setting inside `is_completion_trigger()`,
which only affects LSP completions. This was ok because user-defined
snippets were tacked onto LSP completions. Then #42122 and #42398 made
snippet completions their own thing, similar to word completions,
surfacing #43408. This PR moves the settings check into
`open_or_update_completions_menu()` so it applies to all completions.
Release Notes:
- Fixed setting `show_completions_on_input: false` so that it affects
word and user-defined snippet completions as well as LSP completions
This PR adds word/character diff for expanded diff hunks that have both
a deleted and added section, as well as a setting `word_diff_enabled` to
enable/disable word diffs per language.
- `word_diff_enabled`: Defaults to true. Whether or not expanded diff
hunks will show word diff highlights when they're able to.
### Preview
<img width="1502" height="430" alt="image"

/>
### Architecture
I had three architecture goals I wanted to have when adding word diff
support:
- Caching: We should only calculate word diffs once and save the result.
This is because calculating word diffs can be expensive, and Zed should
always be responsive.
- Don't block the main thread: Word diffs should be computed in the
background to prevent hanging Zed.
- Lazy calculation: We should calculate word diffs for buffers that are
not visible to a user.
To accomplish the three goals, word diffs are computed as a part of
`BufferDiff` diff hunk processing because it happens on a background
thread, is cached until the file is edited, and is only refreshed for
open buffers.
My original implementation calculated word diffs every frame in the
Editor element. This had the benefit of lazy evaluation because it only
calculated visible frames, but it didn't have caching for the
calculations, and the code wasn't organized. Because the hunk
calculations would happen in two separate places instead of just
`BufferDiff`. Finally, it always happened on the main thread because it
was during the `EditorElement` layout phase.
I used Zed's
[`diff_internal`](02b2aa6c50/crates/language/src/text_diff.rs (L230-L267))
as a starting place for word diff calculations because it uses
`Imara_diff` behind the scenes and already has language-specific
support.
#### Future Improvements
In the future, we could add `AST` based word diff highlights, e.g.
https://github.com/zed-industries/zed/pull/43691.
Release Notes:
- git: Show word diff highlight in expanded diff hunks with less than 5
lines.
- git: Add `word_diff_enabled` as a language setting that defaults to
true.

Follow-up to #43586--when the diff is not split, just render the primary
editor. Otherwise the child `Pane` intercepts `CloseActiveItem`. (This
is still a bug for the actual split diff, but just fixing the
user-visible regression for now.)

At some point, rust-analyzer started including the snippet expression
for some completions in the description field, but that can look like a
bug:
<img width="1570" height="578" alt="CleanShot 2025-11-27 at 20 39 49@2x"
src="https://github.com/user-attachments/assets/5a87c9fe-c0a8-472f-8d83-3bc9e9e00bbc"></img>
In these cases, we will now inline the tab stops as an ellipsis
character:
<img width="1544" height="428" alt="CleanShot 2025-12-01 at 10 01 18@2x"
src="https://github.com/user-attachments/assets/4c550891-4545-47cd-a295-a5eb07e78e92"></img>
You may also notice that we now syntax highlight the pattern closer to
what it looks like after accepted.
Alternatively, when the tab stop isn't just one position, it gets
highlighted as a selection since that's what it would do when accepted:
<img width="1558" height="314" alt="CleanShot 2025-12-01 at 10 04 37@2x"
src="https://github.com/user-attachments/assets/ce630ab2-da22-4072-a996-7b71ba21637d"
/>
Release Notes:
- rust: Display completion tab stops inline rather than as a raw LSP
snippet expression
Gist is we only need to block the foreground thread for reparsing if
immediate language changes are useful to the user. That is usually only
the case when they edit the buffer

Note that the truncation strategy on the file path is not yet perfect.
I'm just applying the regular method from the label component, but we
should wrap path text from the start rather than from the end. Some time
in the future!

src="https://github.com/user-attachments/assets/6ebc618a-4b4a-42fd-b5b7-39fec3ae5335"
/>
Release Notes:
- Fixed a bug where the "Open File" button would overflow in the
multibuffer header if the file path was too long.
There is still room for improvement here as `anchor(s)_in_excerpt` is
generally a bad API here due to it reseeking the entire excerpt tree
from the start on every call which we don't really need. But this at
least cuts the seeks down by a factor of 4 for now.
Release Notes:
- Improved performance of bracket colorization in large multibuffers
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
Fixes ZED-3P9
We only clamped the end which for a completely wrong input could cause
us to construct a reversed range which will end up underflowing later
on.
Release Notes:

Current approach is to colorize brackets based on their depth, which was
broken for markdown:
<img width="388" height="50" alt="image"
src="https://github.com/user-attachments/assets/bd8b6c2f-5a26-4d6b-a301-88675bf05920"
/>
Markdown grammar, for bracket queries
00e93bfa11/crates/languages/src/markdown/brackets.scm (L1-L8)
and markdown document `[LLM-powered features](./ai/overview.md), [bring
and configure your own API
keys](./ai/llm-providers.md#use-your-own-keys)`, matches first bracket
(offset 0) with two different ones:
* `[LLM-powered features]`
* `[LLM-powered features](./ai/overview.md), [bring and configure your
own API keys]`
which mix and add different color markers.
Now, in case multiple pairs exist for the same first bracket, Zed will
only colorize the shortest one:
<img width="373" height="33" alt="image"
src="https://github.com/user-attachments/assets/04b3f7af-8927-4a8b-8f52-de8b5bb063ac"
/>
Release Notes:
- Fixed bracket colorization mixing colors in markdown files
Follow-up to https://github.com/zed-industries/zed/pull/39367
Release Notes:
- Fixed a small issue where a scrollbar would sometimes show in the
editor although the content fix exactly on screen.
