Otherwise we can sometimes end up with single line excerpts which looks
very off
Release Notes:
- Improved the minimum size of diagnostics pane excerpts
The function is unsound due to the classic fact that one can leak tasks,
sidestepping the blocking drop behavior resulting in a use after free.

## Summary
Follow-up to https://github.com/zed-industries/zed/discussions/55352,
where the conclusion was to split `editor.rs` incrementally by topic
instead of all at once.
This mechanically extracts diagnostics-related editor code into
`crates/editor/src/editor/diagnostics.rs` while preserving the existing
public API via re-exports.
## Testing
- `cargo check -p editor --lib`
- `cargo check -p diagnostics --lib`
- `cargo check -p diagnostics --tests`

## Context
### Background
Currently, a multibuffer consists of an arbitrary list of
anchor-delimited excerpts from individual buffers. Excerpt ranges for a
fixed buffer are permitted to overlap, and can appear in any order in
the multibuffer, possibly separated by excerpts from other buffers.
However, in practice all code that constructs multibuffers does so using
the APIs defined in the `path_key` submodule of the `multi_buffer` crate
(`set_excerpts_for_path` etc.) If you only use these APIs, the resulting
multibuffer will maintain the following invariants:
- All excerpts for the same buffer appear contiguously in the
multibuffer
- Excerpts for the same buffer cannot overlap
- Excerpts for the same buffer appear in order
- The placement of the excerpts for a specific buffer in the multibuffer
are determined by the `PathKey` passed to `set_excerpts_for_path`. There
is exactly one `PathKey` per buffer in the multibuffer
### Purpose of this PR
This PR changes the multibuffer so that the invariants maintained by the
`path_key` APIs *always* hold. It's no longer possible to construct a
multibuffer with overlapping excerpts, etc. The APIs that permitted
this, like `insert_excerpts_with_ids_after`, have been removed in favor
of the `path_key` suite.
The main upshot of this is that given a `text::Anchor` and a
multibuffer, it's possible to efficiently figure out the unique excerpt
that includes that anchor, if any:
```
impl MultiBufferSnapshot {
fn buffer_anchor_to_anchor(&self, anchor: text::Anchor) -> Option<multi_buffer::Anchor>;
}
```
And in the other direction, given a `multi_buffer::Anchor`, we can look
at its `text::Anchor` to locate the excerpt that contains it. That means
we don't need an `ExcerptId` to create or resolve
`multi_buffer::Anchor`, and in fact we can delete `ExcerptId` entirely,
so that excerpts no longer have any identity outside their
`Range<text::Anchor>`.
There are a large number of changes to `editor` and other downstream
crates as a result of removing `ExcerptId` and multibuffer APIs that
assumed it.
### Other changes
There are some other improvements that are not immediate consequences of
that big change, but helped make it smoother. Notably:
- The `buffer_id` field of `text::Anchor` is no longer optional.
`text::Anchor::{MIN, MAX}` have been removed in favor of
`min_for_buffer`, etc.
- `multi_buffer::Anchor` is now a three-variant enum (inlined slightly):
```
enum Anchor {
Min,
Excerpt {
text_anchor: text::Anchor,
path_key_index: PathKeyIndex,
diff_base_anchor: Option<text::Anchor>,
},
Max,
}
```
That means it's no longer possible to unconditionally access the
`text_anchor` field, which is good because most of the places that were
doing that were buggy for min/max! Instead, we have a new API that
correctly resolves min/max to the start of the first excerpt or the end
of the last excerpt:
```
impl MultiBufferSnapshot {
fn anchor_to_buffer_anchor(&self, anchor: multi_buffer::Anchor) -> Option<text::Anchor>;
}
```
- `MultiBufferExcerpt` has been removed in favor of a new
`map_excerpt_ranges` API directly on `MultiBufferSnapshot`.

Happy New Years! This PR is a second take at
https://github.com/zed-industries/zed/pull/38127 (cc @ConradIrwin)
This PR is significantly less complicated than the last attempt: while
we still keep our data on the `NavigationHistory` object, we no longer
tightly integrate it with the existing back/forward "browser history."
Instead, we keep our own stack of `(origin, target)` pairs (in a struct
to make it easy to extend with e.g., tag names in the future).
The PR is split into two separable commits. Most of the implementation
is in the second commit, which:
- Defines the stack data structure
- Implements `pane::GoToOlderTag` and `pane::GoToNewerTag` in terms of
the stack
- Hooks into `navigate_to_hover_links` to push tag stack entries
This last bit is the most fiddly. The core challenge is that we need to
keep track of the `origin` location and calculate the `target` location
across three codepaths that might involve creating a new editor and/or
splitting the pane. One thing in particular I found difficult was that
an editor's `nav_history` (an `ItemNavHistory`) seems to be populated
asynchronously. Instead of relying on it, I decided in this code to make
my own `ItemNavHistory`. I briefly tried to refactor the code in
question, but it seemed like it would significantly increase the scope
of the change.
I prefer this all-in-one tracking centered around
`navigate_to_hover_links ` to the `start/finish` approach taken in
b69a2ea200
because I find it easier to convince myself that the right data is being
populated at the right times. Of course, let me know if you think
there's a better solution.
Closes#14206
Release Notes:
- ??? I don't know what to write here! Suggestions welcome
Breadcrumb visual reorchestration which makes a couple of key changes:
- Breadcrumbs are now displayed in file headers for multibuffer views.
Singleton buffers are unchanged.
- Multibuffer views now have collapse/expand all buttons available in
the toolbar
- Search in multibuffer views now takes up less space, by occupying the
primary toolbar location erstwhile taken up by breadcrumbs

This mimics VSCode's `files.readonlyExclude` setting, to allow setting
specific path matches as readonly locations like lockfiles and generated
sources etc.
Also renders a lock icon to the right side of the path names for
readonly files now.
This does a couple more things for completion sake:
- Tabs of readonly buffers now render a file lock icon
- Multibuffer buffer headers now render a file lock icon if the excerpts
buffer is readonly
- ReadWrite multibuffers now no longer allow edits to read only buffers
contained within
Release Notes:
- Added `read_only_files` setting to allow specifying glob patterns of
files that should not be editable by default

Closes #ISSUE
Problem:
- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.
Fix:
- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

After:

Release Notes:
- Fixed: pending keybinding prefixes on the status bar now clear
immediately when focus moves to another panel or UI context.

## Summary
The diagnostics panel was ignoring the user's `toolbar.breadcrumbs`
setting and always showing breadcrumbs. This makes both
`BufferDiagnosticsEditor` and `ProjectDiagnosticsEditor` check the
`EditorSettings` to determine whether to display breadcrumbs.
## Changes
- `buffer_diagnostics.rs`: Updated `breadcrumb_location` to check
`EditorSettings::get_global(cx).toolbar.breadcrumbs`
- `diagnostics.rs`: Updated `breadcrumb_location` to check
`EditorSettings::get_global(cx).toolbar.breadcrumbs`
This follows the same pattern used by the regular `Editor` in
`items.rs`.
## Test plan
1. Set `toolbar.breadcrumbs` to `false` in settings.json
2. Open a file with diagnostics
3. Run `diagnostics: deploy current file`
4. Verify that breadcrumbs are hidden in the diagnostics panel

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.

Closes#7844
This change uses tree-sitter highlights as a method of showing
typescript errors prettily, keeping regex as simple as possible:
<img width="832" height="446" alt="Screenshot 2025-11-11 at 3 40 24 PM"
src="https://github.com/user-attachments/assets/0b3b6cf1-4d4d-4398-b89b-ef5ec0df87ec"
/>
It covers three main areas:
1. Diagnostics
Diagnostics are now rendered with language-aware typescript, by
providing the project's language registry.
2. Vtsls
The LSP provider for typescript now implements the
`diagnostic_message_to_markdown` function in the `LspAdapter` trait, so
as to provide Diagnostics with \`\`\`typescript...\`\`\`-style code
blocks for any selection of typescript longer than one word. In the
single-word case, it simply wraps with \`\`
3. Typescript's `highlights.scm`
`vtsls` doesn't provide strictly valid typescript in much of its
messaging. Rather, it returns a message with snippets of typescript
values which are invalid. Tree-sitter was not properly highlighting
these snippets because it was expecting key-value formats. For instance:
```
type foo = { foo: string; bar: string; baz: number[] }
```
is valid, whereas simply
```
{ foo: string; bar: string; baz: number[] }
```
is not.
Therefore, highlights.scm needed to be adjusted in order to
pattern-match on literal values that might be returned from the vtsls
diagnostics messages. This was done by a) identifying arrow functions on
their own, and b) augmenting the `statment_block` pattern matching in
order to match on values which were clearly object literals.
This approach may not be exhaustive - I'm happy to work on any
additional cases we might identify from `vtsls` here - but hopefully
demonstrates an extensible approach to making these messages look nice,
without taking on the technical burden of extensive regex.
Release Notes:
- Show pretty TypeScript errors with language-aware Markdown.
Fixes ZED-2CQ
We were doing the binary search by buffer points, but due to await
points within this function we could end up mixing points of differing
buffer versions.
Release Notes:
- N/A *or* Added/Fixed/Improved ...
Prior we were only updating the diagnostics pane when it is either
unfocued, saved or when a disk based diagnostic run finishes (aka cargo
check). The reason for this is simple, we do not want to take away the
excerpt under the users cursor while they are typing if they manage to
fix the diagnostic. Additionally we need to prevent dropping the changed
buffer before it is saved.
Delaying updates was a simple way to work around these kind of issues,
but comes at a huge annoyance that the diagnostics pane is not actually
reflecting the current state of the world but some snapshot of it
instead making it less than ideal to work within it for languages that
do not leverage disk based diagnostics (that is not rust-analyzer, and
even for rust-analyzer its annoying).
This PR changes this. We now always live update the view but take care
to retain unsaved buffers as well as buffers that contain a cursor in
them (as well as some other "checkpoint" properties).
Release Notes:
- Improved diagnostics pane to live update when editing within its
editor
When trying to split and clone a non clone-able workspace item we now
attempt split and move instead of doing nothing. Additionally we disable
the split menu buttons if we can't split the active item at all.
Release Notes:
- Improved handling of unsplittable panes
