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
int fn_branch(bool do_branch1, bool do_branch2);
```
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#33510https://github.com/zed-extensions/php/issues/29
If certain language servers do not provide an insert/replace range, we
use `surrounding_word` as a fallback for that range, which internally
uses `word_characters`. It makes sense to use
`completion_query_characters` instead of `word_characters` to get that
range, because we use `completion_query_characters` to query completions
in the first place.
That means, for some hypothetical reason (e.g., if the Tailwind server
stops providing insert/replace ranges), we would correctly fall back to
the range "bg-blue-200^" instead of "200^", because
`completion_query_characters` includes "-" in this case.
For this particular fix, right now the default PHP language server
`phpactor` does not provide an insert/replace range, and hence
completion query character is used, which is `$` in this case.
Note that `$` isn't in word characters for reasons mentioned here:
https://github.com/zed-extensions/php/issues/14
Release Notes:
- Fixed an issue where accepting variable completion in PHP would result
in a double $ sign in the prefix.
Closes#33442
Release Notes:
- Resolved an issue where the ESLint language server returned an empty
string for the CodeDescription.href field in diagnostics, leading to
missing diagnostics in editor.
This fixes an issue where lower-priority language servers cannot provide
contentful responses even when the first capable server returned empty
responses.
Most of the diffs are copypasted since the existing implementations were
also copypasted.
Release Notes:
- Improved Go to Definition / Declaration / Type Definition /
Implementation and Find All References to include all results from
different language servers
This PR revives zed-industries/zed#27818 and aims to complete the
partially implemented overloaded signature help feature.
The first commit is a rebase of zed-industries/zed#27818, and the
subsequent commit addresses all review feedback from the original PR.
Now the overloaded signature help works like
https://github.com/user-attachments/assets/e253c9a0-e3a5-4bfe-8003-eb75de41f672Closes#21493
Release Notes:
- Implemented signature help for overloaded items. Additionally, added a
support for rendering signature help documentation.

Closes https://github.com/zed-industries/zed/issues/33522
Turns out a bunch of Zed requests were not checking their capabilities
correctly, due to odd copy-paste and due to default that assumed that
the capabilities are met.
Adjust the code, which includes the document colors, add the test on the
colors case.
Release Notes:
- Fixed excessive document colors requests for unrelated files
https://github.com/user-attachments/assets/ad0fa304-e4fb-4598-877d-c02141f35d6f
Closes https://github.com/zed-industries/zed/issues/4678
Also adds the code to support `textDocument/colorPresentation`
counterpart that serves as a resolve mechanism for the document colors.
The resolve itself is not run though, and the editor does not
accommodate color presentations in the editor yet — until a well
described use case is provided.
Use `lsp_document_colors` editor settings to alter the presentation and
turn the feature off.
Release Notes:
- Start showing inline previews for LSP document colors
Follow-up of https://github.com/zed-industries/zed/pull/19230
`BufferId` can change between file reopens: e.g. open the buffer, close
it, go back in history to reopen it — the 2nd one will have a different
`BufferId`, but the same `result_ids` semantically.
Release Notes:

Follow-up of https://github.com/zed-industries/zed/pull/19230
Implements the workspace diagnostics pulling, and replaces "pull
diagnostics every open editors' buffer" strategy with "pull changed
buffer's diagnostics" + "schedule workspace diagnostics pull" for the
rest of the diagnostics.
This means that if the server does not support the workspace diagnostics
and does not return more in linked files, only the currently edited
buffer has its diagnostics updated.
This is better than the existing implementation that causes a lot of
diagnostics pulls to be done instead, and we can add more heuristics on
top later for querying more diagnostics.
Release Notes:
- N/A
Follow-up of https://github.com/zed-industries/zed/pull/19230
* starts to send `result_id` in pull requests to allow servers to reply
with non-full results
* fixes a bug where disk-based diagnostics were offset after pulling the
diagnostics
* fixes a bug due to which pull diagnostics could not be disabled
* uses better names and comments for the workspace pull diagnostics part
Release Notes:

Closes [#13107](https://github.com/zed-industries/zed/issues/13107)
Enabled pull diagnostics by default, for the language servers that
declare support in the corresponding capabilities.
```
"diagnostics": {
"lsp_pull_diagnostics_debounce_ms": null
}
```
settings can be used to disable the pulling.
Release Notes:
- Added support for the LSP `textDocument/diagnostic` command.
# Brief
This is draft PR that implements the LSP `textDocument/diagnostic`
command. The goal is to receive your feedback and establish further
steps towards fully implementing this command. I tried to re-use
existing method and structures to ensure:
1. The existing functionality works as before
2. There is no interference between the diagnostics sent by a server and
the diagnostics requested by a client.
The current implementation is done via a new LSP command
`GetDocumentDiagnostics` that is sent when a buffer is saved and when a
buffer is edited. There is a new method called `pull_diagnostic` that is
called for such events. It has debounce to ensure we don't spam a server
with commands every time the buffer is edited. Probably, we don't need
the debounce when the buffer is saved.
All in all, the goal is basically to get your feedback and ensure I am
on the right track. Thanks!

## In action
You can clone any Ruby repo since the `ruby-lsp` supports the pull
diagnostics only.
Steps to reproduce:
1. Clone this repo https://github.com/vitallium/stimulus-lsp-error-zed
2. Install Ruby (via `asdf` or `mise).
4. Install Ruby gems via `bundle install`
5. Install Ruby LSP with `gem install ruby-lsp`
6. Check out this PR and build Zed
7. Open any file and start editing to see diagnostics in realtime.

Also adds reuse of the markdown documentation cache even when
completions are re-queried, so that markdown documentation doesn't
flicker when `is_incomplete: true` (completions provided by rust
analyzer always set this)
Release Notes:
- Added support for filtering language server completions instead of
re-querying.
https://github.com/zed-industries/zed/issues/30972 brought up another
case where our context is not enough to track the actual source of the
issue: we get a general top-level error without inner error.
The reason for this was `.ok_or_else(|| anyhow!("failed to read HEAD
SHA"))?; ` on the top level.
The PR finally reworks the way we use anyhow to reduce such issues (or
at least make it simpler to bubble them up later in a fix).
On top of that, uses a few more anyhow methods for better readability.
* `.ok_or_else(|| anyhow!("..."))`, `map_err` and other similar error
conversion/option reporting cases are replaced with `context` and
`with_context` calls
* in addition to that, various `anyhow!("failed to do ...")` are
stripped with `.context("Doing ...")` messages instead to remove the
parasitic `failed to` text
* `anyhow::ensure!` is used instead of `if ... { return Err(...); }`
calls
* `anyhow::bail!` is used instead of `return Err(anyhow!(...));`
Release Notes:
- N/A
Adds actions so you can have customized keybindings for `insert` and
`replace` modes.
And add `shift-enter` as a default for `replace`, this will override the
default setting
`completions.lsp_insert_mode` which is set to `replace_suffix`, which
tries to "smartly"
decide whether to replace or insert based on the surrounding text.
For those who come from VSCode, if you want to mimic their behavior, you
only have to
set `completions.lsp_insert_mode` to `insert`.
If you want `tab` and `enter` to do different things, you need to remap
them, here is
an example:
```jsonc
[
// ...
{
"context": "Editor && showing_completions",
"bindings": {
"enter": "editor::ConfirmCompletionInsert",
"tab": "editor::ConfirmCompletionReplace"
}
},
]
```
Closes#24577
- [x] Make LSP completion insertion mode decision in guest's machine
(host is currently deciding it and not allowing guests to have their own
setting for it)
- [x] Add shift-enter as a hotkey for `replace` by default.
- [x] Test actions.
- [x] Respect the setting being specified per language, instead of using
the "defaults".
- [x] Move `insert_range` of `Completion` to the Lsp variant of
`.source`.
- [x] Fix broken default, forgotten after
https://github.com/zed-industries/zed/pull/27453#pullrequestreview-2736906628,
should be `replace_suffix` and not `insert`.
Release Notes:
- LSP completions: added actions `ConfirmCompletionInsert` and
`ConfirmCompletionReplace` that control how completions are inserted,
these override `completions.lsp_insert_mode`, by default, `shift-enter`
triggers `ConfirmCompletionReplace` which replaces the whole word.
(and any other LSP server in theory, if it exposes any LSP-ext endpoint
for the same)
Closes https://github.com/zed-industries/zed/issues/16160
* adds a way to disable tree-sitter tasks (the ones from the plugins,
enabled by default) with
```json5

language settings
* adds a way to disable LSP tasks (the ones from the rust-analyzer
language server, enabled by default) with
```json5
"lsp": {
"rust-analyzer": {
"enable_lsp_tasks": false,

}
```
* adds rust-analyzer tasks into tasks modal and gutter:

src="https://github.com/user-attachments/assets/bd818079-e247-4332-bdb5-1b7cb1cce768"
/>
Release Notes:
- Added tasks from rust-analyzer
This PR adds `completions.lsp_insert_mode` and effectively changes the
default from `"replace"` to `"replace_suffix"`, which automatically
detects whether to use the LSP `replace` range instead of `insert`
range.
`"replace_suffix"` was chosen as a default because it's more
conservative than `"replace_subsequence"`, considering that deleting
text is usually faster and less disruptive than having to rewrite a long
replaced word.
Fixes#27197Fixes#23395 (again)
Fixes#4816 (again)
Release Notes:
- Added new setting `completions.lsp_insert_mode` that changes what will
be replaced when an LSP completion is accepted. The default is
`"replace_suffix"`, but it accepts 4 values: `"insert"` for replacing
only the text before the cursor, `"replace"` for replacing the whole
text, `"replace_suffix"` that acts like `"replace"` when the text after
the cursor is a suffix of the completion, and `"replace_subsequence"`
that acts like `"replace"` when the text around your cursor is a
subsequence of the completion (similiar to a fuzzy match). Check [the
documentation](https://zed.dev/docs/configuring-zed#LSP-Insert-Mode) for
more information.

Closes#25761#21603
When `text_edit` is not available we directly fallback to to `label`.
That means, when we have range to replace, we never use `insertText` and
only use it when we haven't found any range.
This PR fixes, this and uses `insertText` as fallback first, and then
`label`.
Release Notes:
- Fixed an issue where accepting LSP snippet completion would insert the
label instead of expanding the snippet.
This is the core change:

- [x] Implement it in the whole app
- [x] Implement it in the debugger
- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.

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
60cd01864a/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:
60cd01864a/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
Closes https://github.com/zed-industries/zed/issues/21277
To the left is current Zed, right is the improved version.
3rd message, from Zed, to resolve the item, does not have `textEdit` on
the right side, and has one on the left.
Seems to not influence the end result though, but at least Zed behaves
more appropriate now.
<img width="1727" alt="image"
src="https://github.com/user-attachments/assets/ca1236fd-9ce2-41ba-88fe-1f3178cdcbde"
/>
Instead of modifying the original LSP completion item, store completion
list defaults and apply them when the item is requested (except `data`
defaults, needed for resolve).
Now, the only place that can modify the completion items is this method,
and Python impl seems to be the one doing it:
ca9c3af56f/crates/languages/src/python.rs (L182-L204)
Seems ok to leave untouched for now.
Release Notes:
- Fixed LSP completion items modified before resolve request
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
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
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

the wrong refresh() call being used
- [x] Fix the tests

(Late) follow up to #9634.
Fixes#23395
Release Notes:
- Accepting completions while the cursor is in the middle of suggested
completion will now result in smaller edits being applied.
This PR introduces a new entity called Project Tree which is responsible
for finding subprojects within a worktree;
a subproject is a language-specific subset of a worktree which should be
accurately tracked on the language server side. We'll have an ability to
set multiple disjoint workspaceFolders on language server side OR spawn
multiple instances of a single language server (which will be the case
with e.g. Python language servers, as they need to interact with
multiple disjoint virtual environments).
Project Tree assumes that projects of the same LspAdapter kind cannot
overlap. Additionally project nesting is not allowed within the scope of
a single LspAdapter.
Closes https://github.com/zed-industries/zed/issues/5108
Re-lands #22182 which I had to revert due to merging it into todays
Preview.

- Language servers now track their working directory more accurately.

This adds support for LSPs that use the old rename flow which does not
first ask the LSP for the rename range and check that it is a valid
range to rename.
Closes#16663
Release Notes:
* Fixed rename symbols action when the language server does not have the
capability to prepare renames - such as `luau-lsp`.
Closes https://github.com/zed-industries/zed/issues/19214
Closes https://github.com/zed-industries/zed/pull/22443
Adds `resolved` property into Zed completion item data, to ensure we
resolve every completion item exactly once.
There are 2 paths for singplayer Zed, and corresponding 2 analogues for
multi player code, where resolve may happen:
* completions menu display & selection, that ends up using
`resolve_completions` in `lsp_store.rs`
* applying a completion menu entry, that ends up using
`apply_additional_edits_for_completion` in `lsp_store.rs`
Now, all local counterparts check `enabled` field before resolving and
set it to true afterwards, and reuse the same `resolve_completion_local`
method for resolving the items.
A logic for re-generating docs and item labels was moved out from the
`resolve_completion_local` method into a separate method, as
`apply_additional_edits_for_completion` does not need that, but needs
the rest of the logic for resolving.
During the extraction, I've noted that multiplayer clients are not
getting the item labels, regenerated after the resolve — as the Zed
protocol-based flow is not the exact copy of the local resolving.
To improve that, `resolve_completion_remote` needs to be adjusted, but
this change is omitted to avoid bloating the PR.
Release Notes:
- Fixed autocomplete inserting multiple imports
