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.

This simplifies some code and is also more correct in some others (I
believe some of these might've overflowed causing panics in sentry)

We've been considering removing workspace-hack for a couple reasons:
- Lukas ran into a situation where its build script seemed to be causing
spurious rebuilds. This seems more likely to be a cargo bug than an
issue with workspace-hack itself (given that it has an empty build
script), but we don't necessarily want to take the time to hunt that
down right now.
- Marshall mentioned hakari interacts poorly with automated crate
updates (in our case provided by rennovate) because you'd need to have
`cargo hakari generate && cargo hakari manage-deps` after their changes
and we prefer to not have actions that make commits.
Currently removing workspace-hack causes our workspace to grow from
~1700 to ~2000 crates being built (depending on platform), which is
mainly a problem when you're building the whole workspace or running
tests across the the normal and remote binaries (which is where
feature-unification nets us the most sharing). It doesn't impact
incremental times noticeably when you're just iterating on `-p zed`, and
we'll hopefully get these savings back in the future when
rust-lang/cargo#14774 (which re-implements the functionality of hakari)
is finished.

In the settings refactor I'd assumed server settings were like project

## 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

C projects with `"` as "brackets" that autoclose, may invoke panics when
edited at the end of the file.
With a single selection-caret (`ˇ`), at the end of the file,
```c
ifndef BAR_H
#define BAR_H
#include <stdbool.h>
int fn_branch(bool do_branch1, bool do_branch2);
#endif // BAR_H
#include"ˇ"
```
gets an LSP response from clangd
```jsonc
{
"filterText": "AGL/",
"insertText": "AGL/",
"insertTextFormat": 1,
"kind": 17,
"label": " AGL/",
"labelDetails": {},
"score": 0.78725427389144897,
"sortText": "40b67681AGL/",
"textEdit": {
"newText": "AGL/",
"range": { "end": { "character": 11, "line": 8 }, "start": { "character": 10, "line": 8 } }
}
}
```
which replaces `"` after the caret (character/column 11, 0-indexed).
This is reasonable, as regular follow-up (proposed in further
completions), is a suffix + a closing `"`:
<img width="842" height="259" alt="image"
src="https://github.com/user-attachments/assets/ea56f621-7008-4ce2-99ba-87344ddf33d2"
/>
Yet when Zed handles user input of `"`, it panics due to multiple
reasons:
* after applying any snippet text edit, Zed did a selection change:
5537987630/crates/editor/src/editor.rs (L9539-L9545)
which caused eventual autoclose region invalidation:
5537987630/crates/editor/src/editor.rs (L2970)
This covers all cases that insert the `include""` text.
* after applying any user input and "plain" text edit, Zed did not
invalidate any autoclose regions at all, relying on the "bracket" (which
includes `"`) autoclose logic to rule edge cases out
* bracket autoclose logic detects previous `"` and considers the new
user input as a valid closure, hence no autoclose region needed.
But there is an autoclose bracket data after the plaintext completion
insertion (`AGL/`) really, and it's not invalidated after `"` handling
* in addition to that, `Anchor::is_valid` method in `text` panicked, and
required `fn try_fragment_id_for_anchor` to handle "pointing at odd,
after the end of the file, offset" cases as `false`
A test reproducing the feedback and 2 fixes added: proper, autoclose
region invalidation call which required the invalidation logic tweaked a
bit, and "superficial", "do not apply bad selections that cause panics"
fix in the editor to be more robust
Release Notes:
- Fixed panic with completion ranges and autoclose regions interop

Closes#34390
This PR fixes several Bash indentation issues:
- Adding indentation or comment using multi cursors no longer breaks
relative indentation
- Adding newline now places the cursor at the correct indent
- Typing a valid keyword triggers context-aware auto outdent
It also adds tests for all of them.
Release Notes:
- Fixed various issues with handling indentation in Bash.
Closes#33761
The problem was that in the indentation regex we were treating lines
that had `:` in them as requiring an indent on the next line, even if
that `:` was inside a comment.
Release Notes:
- Fixed YAML indentation for lines containing comments with `:` in them
Closes#19644#18151
Now, rewrapping markdown lists (unordered, ordered, and to-do lists) and
block quotes wrap them separately, without merging them together.
Additionally, it correctly indents subsequent lines.
With this input:
```md
1. This is a list item that is short.
2. This list item is a bit longer because I want to see if it wraps correctly after a rewrap operation in Zed. What do you think?
3. another short item
```
Output would be:
```md
1. This is a list item that is short.
2. This list item is a bit longer because I want to see if it wraps correctly
after a rewrap operation in Zed. What do you think?
3. another short item
```
Instead of:
```md
1. This is a list item that is short. 2. This list item is a bit longer because
I want to see if it wraps correctly after a rewrap operation in Zed. What
do you think? 3. another short item
```
Release Notes:
- Improved rewrap for markdown lists, todos, and block quotes.
As part of this I refactored the logic that enabled/disabled actions in
the debugger to happen at action registration time instead of using
command palette filters. This allows the menu to grey out actions correctly.
Release Notes:
- Add a "Run" menu to contain tasks and debugger
* stopped fetching LSP tasks for too long (but still use the hardcoded
value for the time being — the LSP tasks settings part is a simple bool
key and it's not very simple to fit in another value there)
* introduced `prefer_lsp` language task settings value, to control
whether in the gutter/modal/both/none LSP tasks are shown exclusively,
if possible
Release Notes:
- Added a way to prefer LSP tasks over Zed tasks
Don't hard wrap interactively; instead, soft wrap in `Bounded` mode
(editor width or 72 chars, whichever is smaller), and then hard wrap
before sending the commit message to git.
This also makes the soft wrap mode and width for commit messages
configurable in language settings.
Previously we didn't support soft wrap modes other than `EditorWidth` in
auto-height editors; I tried to add support for this by analogy with
code that was already there, and it seems to work pretty well.
Closes#27508
Release Notes:
- Fixed confusing wrapping behavior in commit message editors.
This includes the following data:
- Where we spawned the session from (gutter, scenario list, custom form
filled by the user)
- Which debug adapter was used
- Which dock the debugger is in
Closes #ISSUE
Release Notes:
- debugger: Added telemetry for new session experience that includes

## Summary
### Actions
This PR implements actions that allow a user to "run to cursor" and
"evaluate selected text" while there's an active debug session and
exposes the functionality to the UI as well.
- Run to cursor: Can be accessed by right clicking on the gutter
- Evaluate selected text: Can be accessed by selecting text then right
clicking in the editor
### Bug fixes
I also fixed these bugs as well
- Panic when using debugger: Stop action
- Debugger actions command palette filter not working properly in all
cases
- We stopped displaying the correct label in the session's context menu
when a session was terminated

This adds a "workspace-hack" crate, see
[mozilla's](https://hg.mozilla.org/mozilla-central/file/3a265fdc9f33e5946f0ca0a04af73acd7e6d1a39/build/workspace-hack/Cargo.toml#l7)
for a concise explanation of why this is useful. For us in practice this
means that if I were to run all the tests (`cargo nextest r
--workspace`) and then `cargo r`, all the deps from the previous cargo
command will be reused. Before this PR it would rebuild many deps due to
resolving different sets of features for them. For me this frequently
caused long rebuilds when things "should" already be cached.
To avoid manually maintaining our workspace-hack crate, we will use
[cargo hakari](https://docs.rs/cargo-hakari) to update the build files
when there's a necessary change. I've added a step to CI that checks
whether the workspace-hack crate is up to date, and instructs you to
re-run `script/update-workspace-hack` when it fails.
Finally, to make sure that people can still depend on crates in our
workspace without pulling in all the workspace deps, we use a `[patch]`
section following [hakari's
instructions](https://docs.rs/cargo-hakari/0.9.36/cargo_hakari/patch_directive/index.html)
One possible followup task would be making guppy use our
`rust-toolchain.toml` instead of having to duplicate that list in its
config, I opened an issue for that upstream: guppy-rs/guppy#481.
TODO:
- [x] Fix the extension test failure
- [x] Ensure the dev dependencies aren't being unified by Hakari into
the main dependencies
- [x] Ensure that the remote-server binary continues to not depend on
LibSSL

This PR adds functionality for loading the diff for an arbitrary git
commit, and displaying it in a tab. To retrieve the diff for the commit,
I'm using a single `git cat-file --batch` invocation to efficiently load
both the old and new versions of each file that was changed in the
commit.
Todo
* Features
* [x] Open the commit view when clicking the most recent commit message
in the commit panel
* [x] Open the commit view when clicking a SHA in a git blame column
* [x] Open the commit view when clicking a SHA in a commit tooltip
* [x] Make it work over RPC
* [x] Allow buffer search in commit view
* [x] Command palette action to open the commit for the current blame
line
* Styling
* [x] Add a header that shows the author, timestamp, and the full commit
message
* [x] Remove stage/unstage buttons in commit view
* [x] Truncate the commit message in the tab
* Bugs
* [x] Dedup commit tabs within a pane
* [x] Add a tooltip to the tab
Release Notes:
- Added the ability to show past commits in Zed. You can view the most
recent commit by clicking its message in the commit panel. And when
viewing a git blame, you can show any commit by clicking its sha.
### DISCLAIMER
> As of 6th March 2025, debugger is still in development. We plan to
merge it behind a staff-only feature flag for staff use only, followed
by non-public release and then finally a public one (akin to how Git
panel release was handled). This is done to ensure the best experience
when it gets released.

Implemented by kicking of a task on the main thread at the end of
`Editor::handle_input` which waits for the buffer to be re-parsed before
checking if JSX tag completion possible based on the recent edits, and
if it is then it spawns a task on the background thread to generate the
edits to be auto-applied to the buffer

When formatting buffers or reloading them after they change on disk, we
performed a diff between the buffer's current contents and the new
content. We need this diff in order preserve the positions of cursors
and other decorations when updating the buffer's text.
In order to handle changes within lines, we would previously compute a
*character-wise* diff. This was extremely expensive for large files.
This PR gets rid of the character-wise diff, and instead performs a
normal line-wise diff. Then, for certain replace hunks, we compute a
secondary word-based diff. Also, I've switched to the
[`imara-diff`](https://github.com/pascalkuthe/imara-diff) crate, instead
of `similar`.
Release Notes:
- Fixed a hang that could occur when large files were changed on disk or
formatted.
Release Notes:
- Render unstaged hunks in the project diff editor with a slashed
background

This is a refactoring PR that does three things:
- First, it introduces a new `diff` crate that holds the previous
contents of the `git::diff` module, plus the `BufferChangeSet` type
formerly of `project::buffer_store`. The new crate is necessary since
simply moving `BufferChangeSet` into `git::diff` results in a dependency
cycle due to the use of `language::Buffer` to represent the diff base in
`BufferChangeSet`.
- Second, it renames the two main types in the new diff crate:
`BufferDiff` becomes `BufferDiffSnapshot`, and `BufferChangeSet` becomes
`BufferDiff`. This reflects that the relationship between these two
types (immutable cheaply-cloneable "value" type + stateful "resource
type" with subscriptions) mirrors existing pairs like
`Buffer`/`BufferSnapshot`. References to "change sets" throughout the
codebase are updated to refer to "diffs" instead.
- Finally, it moves the base_text field of the new BufferDiff type to
BufferDiffSnapshot.

Part of https://github.com/zed-industries/zed/issues/20925
This prototype is behind a feature flag and being merged to avoid
conflicts with further git-related resturctures.
To be a proper, public feature, this needs at least:
* showing deleted files
* better performance
* randomized tests
* `TODO`s in the `project_diff.rs` file fixed
The good thing is, >90% of the changes are in the `project_diff.rs` file
only, have a basic test and already work on simple cases.

This PR extracts the `InlineCompletionProvider` trait and its related
types out of `editor` and into a new `inline_completion` crate.
By doing so we're able to remove a dependency on `editor` from the
`copilot` and `supermaven` crates.
We did have to move `editor::Direction` into the `inline_completion`
crate, as it is referenced by the `InlineCompletionProvider`. This
should find a better home, at some point.

Fixes https://github.com/zed-industries/zed/issues/18405
In https://github.com/zed-industries/zed/pull/18313, we introduced a
problem where git addition highlights might spuriously return when
undoing certain changes. It turned out, there were already some cases
where git hunk highlighting was incorrect when editing at the boundaries
of expanded diff hunks.
In this PR, I've introduced a test helper method for more rigorously
(and readably) testing the editor's git state. You can assert about the
entire state of an editor's diff decorations using a formatted diff:
```rust
cx.assert_diff_hunks(
r#"
- use some::mod1;
use some::mod2;
const A: u32 = 42;
- const B: u32 = 42;
const C: u32 = 42;
fn main() {
- println!("hello");
+ //println!("hello");
println!("world");
+ //
+ //
}
fn another() {
println!("another");
+ println!("another");
}
- fn another2() {
println!("another2");
}
"#
.unindent(),
);
```
This will assert about the editor's actual row highlights, not just the
editor's internal hunk-tracking state.
I rewrote all of our editor diff tests to use these more high-level
assertions, and it caught the new bug, as well as some pre-existing bugs
in the highlighting of added content.
The problem was how we *remove* highlighted rows. Previously, it relied
on supplying exactly the same range as one that we had previously
highlighted. I've added a `remove_highlighted_rows(ranges)` APIs which
is much simpler - it clears out any row ranges that intersect the given
ranges (which is all that we need for the Git diff use case).
Release Notes:

This PR adds a rewrap command to the editor.
Executing this command will rewrap the text in the selection to the
maximum line width:
https://github.com/user-attachments/assets/69aa9428-17fd-4315-89f1-f354d0f5f459
If there isn't an active selection, the selection will be expanded to
contiguous text from the cursor's location.
Rewrapping only works in Markdown, Plain Text, and within comments for
any other language.
Release Notes:
- Added an `editor: rewrap` command for rewrapping text to the maximum
line width.
