Similar to how tasks are fetched via LSP, also queries for document's
code lens and filters the ones with the commands, supported in server
capabilities.
Whatever's left and applicable to the range given, is added to the
actions menu:

This way, Zed can get more actions to run, albeit neither r-a nor vtsls
seem to provide anything by default.
Currently, there are no plans to render code lens the way as in VSCode,
it's just the extra actions that are show in the menu.
------------------
As part of the attempts to use rust-analyzer LSP data about the
runnables, I've explored a way to get this data via standard LSP.
When particular experimental client capabilities are enabled (similar to
how clangd does this now), r-a starts to send back code lens with the
data needed to run a cargo command:
```
{"jsonrpc":"2.0","id":48,"result":{"range":{"start":{"line":0,"character":0},"end":{"line":98,"character":0}},"command":{"title":"▶︎ Run Tests","command":"rust-analyzer.runSingle","arguments":[{"label":"test-mod tests::ecparser","location":{"targetUri":"file:///Users/someonetoignore/work/ec4rs/src/tests/ecparser.rs","targetRange":{"start":{"line":0,"character":0},"end":{"line":98,"character":0}},"targetSelectionRange":{"start":{"line":0,"character":0},"end":{"line":98,"character":0}}},"kind":"cargo","args":{"environment":{"RUSTC_TOOLCHAIN":"/Users/someonetoignore/.rustup/toolchains/1.85-aarch64-apple-darwin"},"cwd":"/Users/someonetoignore/work/ec4rs","overrideCargo":null,"workspaceRoot":"/Users/someonetoignore/work/ec4rs","cargoArgs":["test","--package","ec4rs","--lib"],"executableArgs":["tests::ecparser","--show-output"]}}]}}}
```
This data is passed as is to VSCode task processor, registered in
https://github.com/rust-lang/rust-analyzer/blob/60cd01864a2d0d6e2231becee402ba063b59dfa1/editors/code/src/main.ts#L195
where it gets eventually executed as a VSCode's task, all handled by the
r-a's extension code.
rust-analyzer does not declare server capabilities for such tasks, and
has no `workspace/executeCommand` handle, and Zed needs an interactive
terminal output during the test runs, so we cannot ask rust-analyzer
more than these descriptions.
Given that Zed needs experimental capabilities set to get these lens:
https://github.com/rust-lang/rust-analyzer/blob/60cd01864a2d0d6e2231becee402ba063b59dfa1/editors/code/src/client.ts#L318-L327
and that the lens may contain other odd tasks (e.g. docs opening or
references lookup), a protocol extension to get runnables looks more
preferred than lens:
https://rust-analyzer.github.io/book/contributing/lsp-extensions.html#runnables
This PR does not include any work on this direction, limiting to the
general code lens support.
As a proof of concept, it's possible to get the lens and even attempt to
run it, to no avail:

Release Notes:
- Used `textDocument/codeLens` data in the actions menu when applicable
Follow-up of https://github.com/zed-industries/zed/pull/26410
* Extract word completions into their own, `editor::ShowWordCompletions`
action so those could be triggered independently of completions
* Assign `ctrl-shift-space` binding to this new action
* Still keep words returned along the completions as in the original PR,
but:
* Tone down regular completions' fallback logic, skip words when the
language server responds with empty list of completions, but keep on
adding words if nothing or an error were returned instead
* Adjust the defaults to wait for LSP completions infinitely
* Skip "words" with digits such as `0_usize` or `2.f32` from completion
items, unless a completion query has digits in it
Release Notes:
- N/A
Because of #26562, it is now possible to subscribe to extension update
events within the LSP store, where we can then update the Schemas sent
to the JSON LSP resulting in dynamic updates to the auto-complete
suggestions and diagnostics in settings. Notably, this means newly
installed languages and (icon) themes will auto-complete correctly as
soon as the extension is installed.
Closes#15436
Release Notes:
- Fixed an issue where autocomplete suggestions and diagnostics for
languages and (icon) themes in settings would not update when the
extension with which they were added was installed or uninstalled
Closes https://github.com/zed-industries/zed/issues/4957https://github.com/user-attachments/assets/ff491378-376d-48ec-b552-6cc80f74200b
Adds `"completions"` language settings section, to configure LSP and
word completions per language.
Word-based completions may be turned on never, always (returned along
with the LSP ones), and as a fallback if no LSP completion items were
returned.
Future work:
* words are matched with the same fuzzy matching code that the rest of
the completions are
This might worsen the completion menu's usability even more, and will
require work on better completion sorting.
* completion entries currently have no icons or other ways to indicate
those are coming from LSP or from word search, or from something else
* we may work with language scopes more intelligently, group words by
them and distinguish during completions
Release Notes:
- Supported word-based completions
---------

A preparation for https://github.com/zed-industries/zed/issues/4957 that
pushes all LSP-related data out from the basic completion item, so that
it's possible to create completion items without any trace of LSP
clearly.
Release Notes:
- N/A
This reduces the number of multibuffer syncs from 100,000 to 20,000.
Before this change each editor individually observed the project, so
literally any project change was amplified by the number of editors you
had open.
Now editors listen to their buffers instead of the project, and other
users of `cx.observe` on the project have been updated to use specific
events to reduce churn.
Follow up to #26237
Release Notes:
- Improved performance of Zed in large repos with lots of file system
events.
---------

Release Notes:
- Git Beta: Fixed a bug where discarding a hunk in the project diff view
performed two concurrent saves of the buffer.
- Git Beta: Fixed an issue where diff hunks appeared in the wrong state
after failing to write to the git index.
Closes#10004
This PR adds support for the organize imports action. Previously, you
had to manually configure it in the settings and then use format to run
it.
Note: Default key binding will be `alt-shift-o` which is similar to
VSCode's organize import. Also, because `cmd-shift-o` is taken by
outline picker.
Todo:
- [x] Initial working
- [x] Handle remote
- [x] Handle multi buffer
- [x] Can we make it generic for executing any code action?
Release Notes:
- Added `editor:OrganizeImports` action to organize imports (sort,
remove unused, etc) for supported LSPs. You can trigger it by using the
`alt-shift-o` key binding.
While looking at Biome LSP implementation I've noticed that they
register their rename capability dynamically, which we don't handle.
Release Notes:
- N/A
Release Notes:
- Improved Zed's handling of the following requests when the first
language server in language server settings for a given language is not
capable of handling them:
- Perform Rename
- Prepare Rename
- Document Highlights
- Find all references
- Go to implementation
- Go to definition
- Go to declaration
- Go to type definition
A call to register_buffer_with_language_servers could nuke existing
snapshots, even when the buffer was already registered with a server.
Essentially, had we had the else branch in place, this would have been
detected.
Closes #ISSUE
Release Notes:
- Fixed Rust analyzer renames sometimes failing. (Preview only)
Closes https://github.com/zed-industries/zed/issues/10122
Closes https://github.com/zed-industries/zed/issues/25034
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.
The language::markdown crate had been superceded by markdown::Mardown.
After #25117, the only two remaining use-cases were rendering git commit
messages (which are arguably not really markdown) and the signature help
(which is definitely not markdown).
Updated the former to use the new markdown component, and the latter to
do syntax highlighting manually.
Release Notes:
- Allow selecting the commit message in git commits
This reverts commit 9ef0501853 due to a
panic.

This PR makes progress on #7711 by identifying any common prefix of the
paths in the file finder's search results, and replacing the "interior"
of that prefix---every path segment but the first and last---with `...`,
when a heuristic indicates that the longest path would otherwise
overflow the modal.
The elision is not applied to any segment that contains a match for the
search query.
There may be more work to do on #7711 in the case of long result paths
that do not share a significant common prefix.
Release Notes:
- Improved display of long paths in the file finder modal

Some language servers report version 0 even if the buffer hasn't been
opened yet. We detect this case and treat it as if the version was
`None`.
Closes#23706
Release Notes:
- Fixed a bug that prevented renames for some languages.
Previously, if multiple formatters were specified for the same language,
they would be run in parallel on the state of the file, and then all
edits would be applied. This lead to incorrect output with many unwanted
artifacts.
This PR refactors the formatting code to clean it up, and ensure results
from previous formatters are passed in to subsequent formatters.
Closes#15544
Release Notes:
- Fixed an issue where when running multiple formatters they would be
ran in parallel rather than sequentially, leading to unwanted artifacts
and incorrect output.

This PR makes it so we send up the diagnostic groups as additional data
with the edit prediction request.
We're not yet making use of them, but we are recording them so we can
use them later (e.g., to train the model).

- **store `buffer::Diagnostic`as NumberOrString instead of assuming
String**
- **update zed-industries/lsp-types rev**
Closes#24081
Release Notes:
- Fixed an issue where language server diagnostic codes would be converted to strings leading to errors with some language servers
## Context
While looking through the client crate, I noticed that some of the old
functions and variables were still using gpui::model name that was
deprecated during the gpui3 transition. This PR renames those instances
of model to entity to be more inline with gpui3.
In addition, I also renamed `model` to `entity` in cases found by the
below search terms given by @someone13574
- model = cx.
- model: Entity
- model: &Entity
- OpenedModelHandle
- model.update
- model.upgrade
- model = .*\.root (regex)
- parent_model
- model = cx.new
- cx.spawn(move |model

This can only happen when either `label.runs` or `label.filter_range`
has a range that's larger than the label text, which is an error.
Instead of panicking, log such errors and fall back to last index (which
is not really helpful, but still).

Fix a bug where a GPUI macro still used `ModelContext`
Rename `AsyncAppContext` -> `AsyncApp`
Rename update_model, read_model, insert_model, and reserve_model to
update_entity, read_entity, insert_entity, and reserve_entity
Release Notes:
- N/A
There's still a bit more work to do on this, but this PR is compiling
(with warnings) after eliminating the key types. When the tasks below
are complete, this will be the new narrative for GPUI:
- `Entity<T>` - This replaces `View<T>`/`Model<T>`. It represents a unit
of state, and if `T` implements `Render`, then `Entity<T>` implements
`Element`.
- `&mut App` This replaces `AppContext` and represents the app.
- `&mut Context<T>` This replaces `ModelContext` and derefs to `App`. It
is provided by the framework when updating an entity.
- `&mut Window` Broken out of `&mut WindowContext` which no longer
exists. Every method that once took `&mut WindowContext` now takes `&mut
Window, &mut App` and every method that took `&mut ViewContext<T>` now
takes `&mut Window, &mut Context<T>`
Not pictured here are the two other failed attempts. It's been quite a
month!
Tasks:
- [x] Remove `View`, `ViewContext`, `WindowContext` and thread through
`Window`
- [x] [@cole-miller @mikayla-maki] Redraw window when entities change
- [x] [@cole-miller @mikayla-maki] Get examples and Zed running
- [x] [@cole-miller @mikayla-maki] Fix Zed rendering
- [x] [@mikayla-maki] Fix todo! macros and comments
- [x] Fix a bug where the editor would not be redrawn because of view
caching
- [x] remove publicness window.notify() and replace with
`AppContext::notify`
- [x] remove `observe_new_window_models`, replace with
`observe_new_models` with an optional window
- [x] Fix a bug where the project panel would not be redrawn because of
the wrong refresh() call being used
- [x] Fix the tests
- [x] Fix warnings by eliminating `Window` params or using `_`
- [x] Fix conflicts
- [x] Simplify generic code where possible
- [x] Rename types
- [ ] Update docs
### issues post merge
- [x] Issues switching between normal and insert mode
- [x] Assistant re-rendering failure

Closes#12553
* [x] Fix `diff_hunk_before`
* [x] Fix failure to show deleted text when expanding hunk w/ cursor on
second line of the hunk
* [x] Failure to expand diff hunk below the cursor.
* [x] Delete the whole file, and expand the diff. Backspace over the

* [x] Go-to-line now counts the diff hunks, but it should not
* [x] backspace at the beginning of a deleted hunk deletes too much text
* [x] Indent guides are rendered incorrectly
* [ ] Fix randomized multi buffer tests
Maybe:
* [ ] Buffer search should include deleted text (in vim mode it turns
out I use `/x` all the time to jump to the next x I can see).
* [ ] vim: should refuse to switch into insert mode if selection is
fully within a diff.
* [ ] vim `o` command when cursor is on last line of deleted hunk.
* [ ] vim `shift-o` on first line of deleted hunk moves cursor but
doesn't insert line
* [x] `enter` at end of diff hunk inserts a new line but doesn't move
cursor
* [x] (`shift-enter` at start of diff hunk does nothing)
* [ ] Inserting a line just before an expanded hunk collapses it
Release Notes:
- Improved diff rendering, allowing you to navigate with your cursor
inside of deleted text in diff hunks.
