## Summary
This PR creates separate functions to check whether the document path is
excluded for linting or formatting. The main motivation is to avoid the
double `Option` for the call sites and makes passing the correct
settings simpler.
## Summary
Refer to the VS Code PR
(https://github.com/astral-sh/ruff-vscode/pull/659) for details on the
change.
This PR changes the following:
1. Add tracing span for both request (request id and method name) and
notification (method name) handler
2. Remove the `RUFF_TRACE` environment variable. This was being used to
turn on / off logging for the server
3. Similarly, remove reading the `trace` value from the initialization
options
4. Remove handling the `$/setTrace` notification
5. Remove the specialized `TraceLogWriter` used for Zed and VS Code
(https://github.com/astral-sh/ruff/pull/12564)
Regarding the (5) for the Zed editor, the reason that was implemented
was because there was no way of looking at the stderr messages in the
editor which has been changed. Now, it captures the stderr as part of
the "Server Logs".
(82492d74a8/crates/language_tools/src/lsp_log.rs (L548-L552))
### Question
Regarding (1), I think having just a simple trace level message should
be good for now as the spans are not hierarchical. This could be tackled
with #12744. The difference between the two:

**Todo**
- [x] Update documentation (I'll be adding a troubleshooting section
under "Editors" as a follow-up which is for all editors)
- [x] Check for backwards compatibility. I don't think this should break
backwards compatibility as it's mainly targeted towards improving the
debugging experience.
~**Before I go on to updating the documentation, I'd appreciate initial
review on the chosen approach.**~

## Summary
This PR updates the language server to avoid indexing the workspace for
single-file mode.
**What's a single-file mode?**
When a user opens the file directly in an editor, and not the folder
that represents the workspace, the editor usually can't determine the
workspace root. This means that during initializing the server, the
`workspaceFolders` field will be empty / nil.
Now, in this case, the server defaults to using the current working
directory which is a reasonable default assuming that the directory
would point to the one where this open file is present. This would allow
the server to index the directory itself for any config file, if
present.
It turns out that in VS Code the current working directory in the above
scenario is the system root directory `/` and so the server will try to
index the entire root directory which would take a lot of time. This is
the issue as described in
https://github.com/astral-sh/ruff-vscode/issues/627. To reproduce, refer
https://github.com/astral-sh/ruff-vscode/issues/627#issuecomment-2401440767.
This PR updates the indexer to avoid traversing the workspace to read
any config file that might be present. The first commit
(8dd2a31eef)
refactors the initialization and introduces two structs `Workspaces` and
`Workspace`. The latter struct includes a field to determine whether
it's the default workspace. The second commit
(61fc39bdb6)
utilizes this field to avoid traversing.
Closes: #11366
## Editor behavior
This is to document the behavior as seen in different editors. The test
scenario used has the following directory tree structure:
```
.
├── nested
│ ├── nested.py
│ └── pyproject.toml
└── test.py
```
where, the contents of the files are:
**test.py**
```py
import os
```
**nested/nested.py**
```py
import os
import math
```
**nested/pyproject.toml**
```toml
[tool.ruff.lint]
select = ["I"]
```
Steps:
1. Open `test.py` directly in the editor
2. Validate that it raises the `F401` violation
3. Open `nested/nested.py` in the same editor instance
4. This file would raise only `I001` if the `nested/pyproject.toml` was
indexed
### VS Code
When (1) is done from above, the current working directory is `/` which
means the server will try to index the entire system to build up the
settings index. This will include the `nested/pyproject.toml` file as
well. This leads to bad user experience because the user would need to
wait for minutes for the server to finish indexing.
This PR avoids that by not traversing the workspace directory in
single-file mode. But, in VS Code, this means that per (4), the file
wouldn't raise `I001` but only raise two `F401` violations because the
`nested/pyproject.toml` was never resolved.
One solution here would be to fix this in the extension itself where we
would detect this scenario and pass in the workspace directory that is
the one containing this open file in (1) above.
### Neovim
**tl;dr** it works as expected because the client considers the presence
of certain files (depending on the server) as the root of the workspace.
For Ruff, they are `pyproject.toml`, `ruff.toml`, and `.ruff.toml`. This
means that the client notifies us as the user moves between single-file
mode and workspace mode.
https://github.com/astral-sh/ruff/pull/13770#issuecomment-2416608055
### Helix
Same as Neovim, additional context in
https://github.com/astral-sh/ruff/pull/13770#issuecomment-2417362097
### Sublime Text
**tl;dr** It works similar to VS Code except that the current working
directory of the current process is different and thus the config file
is never read. So, the behavior remains unchanged with this PR.
https://github.com/astral-sh/ruff/pull/13770#issuecomment-2417362097
### Zed
Zed seems to be starting a separate language server instance for each
file when the editor is running in a single-file mode even though all
files have been opened in a single editor instance.
(Separated the logs into sections separated by a single blank line
indicating 3 different server instances that the editor started for 3
files.)

```
## Test Plan
When using the `ruff` server from this PR, we see that the server starts
quickly as seen in the logs. Next, when I switch to the release binary,
it starts indexing the root directory.
For more details, refer to the "Editor Behavior" section above.
## Summary
When working on improving Ruff integration with Zed I noticed that it
errors out when we try to resolve a code action of a `QUICKFIX` kind;
apparently, per @dhruvmanila we shouldn't need to resolve it, as the
edit is provided in the initial response for the code action. However,
it's possible for the `resolve` call to fill out other fields (such as
`command`).
AFAICT Helix also tries to resolve the code actions unconditionally (as
in, when either `edit` or `command` is absent); so does VSC. They can
still apply the quickfixes though, as they do not error out on a failed
call to resolve code actions - Zed does. Following suit on Zed's side
does not cut it though, as we still get a log request from Ruff for that
failure (which is surfaced in the UI).
There are also other language servers (such as
[rust-analyzer](c1c9e10f72/crates/rust-analyzer/src/handlers/request.rs (L1257)))
that fill out both `command` and `edit` fields as a part of code action
resolution.
This PR makes the resolve calls for quickfix actions return the input
value.

## Summary
Follow-up from #11901
This PR adds a new server setting to show / hide syntax errors.
## Test Plan
### VS Code
Using https://github.com/astral-sh/ruff-vscode/pull/504 with the
following config:
```json
{
"ruff.nativeServer": true,
"ruff.path": ["/Users/dhruv/work/astral/ruff/target/debug/ruff"],
"ruff.showSyntaxErrors": true
}
```
First, set `ruff.showSyntaxErrors` to `true`:

src="5d77547a-a908-4a00-8714-7c00784e8679">
And then set it to `false`:

### Neovim
Using the following Ruff server config:
```lua
require('lspconfig').ruff.setup {
init_options = {
settings = {
showSyntaxErrors = false,
},
},
}
```
First, set `showSyntaxErrors` to `true`:

## Summary
Follow-up to #11902
This PR simplifies the `LinterResult` struct by avoiding the generic and
not store the `ParseError`.
This is possible because the callers already have access to the
`ParseError` via the `Parsed` output. This also means that we can
simplify the return type of `check_path` and avoid the generic `T` on
`LinterResult`.
## Test Plan
`cargo insta test`
## Summary
Fixes#11651.
Fixes#11851.
We were double-closing a notebook document from the index, once in
`textDocument/didClose` and then in the `notebookDocument/didClose`
handler. The second time this happens, taking a snapshot fails.
I've rewritten how we handle snapshots for closing notebooks / notebook
cells so that any failure is simply logged instead of propagating
upwards. This implementation works consistently even if we don't receive
`textDocument/didClose` notifications for each specific cell, since they
get closed (and the diagnostics get cleared) in the notebook document
removal process.
## Test Plan
1. Open an untitled, unsaved notebook with the `Create: New Jupyter
Notebook` command from the VS Code command palette (`Ctrl/Cmd + Shift +
P`)
2. Without saving the document, close it.
3. No error popup should appear.
4. Run the debug command (`Ruff: print debug information`) to confirm
that there are no open documents
## Summary
Fixes https://github.com/astral-sh/ruff-vscode/issues/496.
Cells are no longer removed from the notebook index when a notebook gets
updated, but rather when `textDocument/didClose` is called for them.
This solves an issue where their premature removal from the notebook
cell index would cause their URL to be un-queryable in the
`textDocument/didClose` handler.
## Test Plan
Create and then delete a notebook cell in VS Code. No error should
appear.
## Summary
This PR updates the server capabilities to include the commands that
Ruff supports. This is similar to how there's a list of possible code
actions supported by the server.
I noticed this when I was trying to find whether Helix supported
workspace commands or not based on Jane's comment
(https://github.com/astral-sh/ruff/pull/11831#discussion_r1634984921)
and I found the `:lsp-workspace-command` in the editor but it didn't
show up anything in the picker.
So, I looked at the implementation in Helix
(9c479e6d2d/helix-term/src/commands/typed.rs (L1372-L1384))
which made me realize that Ruff doesn't provide this in its
capabilities. Currently, this does require `ruff` to be first in the
list of language servers in the user config but that should be resolved
by https://github.com/helix-editor/helix/pull/10176. So, the following
config should work:
```toml
[[language]]
name = "python"
# Ruff should come first until https://github.com/helix-editor/helix/pull/10176 is released
language-servers = ["ruff", "pyright"]
```
## Test Plan
1. Neovim's server capabilities output should include the supported
commands:
```
executeCommandProvider = {
commands = { "ruff.applyFormat", "ruff.applyAutofix", "ruff.applyOrganizeImports", "ruff.printDebugInformation" },
workDoneProgress = false
},
```
2. Helix should now display the commands to pick from when
`:lsp-workspace-command` is invoked:

src="09048ecd-c974-4e09-ab56-9482ff3d780b">
## Summary
Fixes#11744.
We now show a distinct popup message when we fail to get a document
snapshot during command execution. This message more clearly
communicates the issue to the user, instead of a generic "ruff
encountered an error" message.
## Test Plan
Try running `Fix all auto-fixable problems` on an incompatible file (for
example: `settings.json`). You should see the following popup message:
<img width="456" alt="Screenshot 2024-06-11 at 11 47 16 AM"
src="3a28e3d7-3896-4dd0-b117-f87300dd3b68">
## Summary
Closes#11715.
Introduces a new command, `ruff.printDebugInformation`. This will print
useful information about the status of the server to `stderr`.
Right now, the information shown by this command includes:
* The path to the server executable
* The version of the executable
* The text encoding being used
* The number of open documents and workspaces
* A list of registered configuration files
* The capabilities of the client
## Test Plan
First, checkout and use [the corresponding `ruff-vscode`
PR](https://github.com/astral-sh/ruff-vscode/pull/495).
Running the `Print debug information` command in VS Code should show
something like the following in the Output channel:

src="ab93c009-bb7b-4291-b057-d44fdc6f9f86">
## Summary
Fixes#10968.
Fixes#11545.
The server's tracing system has been rewritten from the ground up. The
server now has trace level and log level settings which restrict the
tracing events and spans that get logged.
* A `logLevel` setting has been added, which lets a user set the log
level. By default, it is set to `"info"`.
* A `logFile` setting has also been added, which lets the user supply an
optional file to send tracing output (it does not have to exist as a
file yet). By default, if this is unset, tracing output will be sent to
`stderr`.
* A `$/setTrace` handler has also been added, and we also set the trace
level from the initialization options. For editors without direct
support for tracing, the environment variable `RUFF_TRACE` can override
the trace level.
* Small changes have been made to how we display tracing output. We no
longer use `tracing-tree`, and instead use
`tracing_subscriber::fmt::Layer` to format output. Thread names are now
included in traces, and I've made some adjustment to thread worker names
to be more useful.
## Test Plan
In VS Code, with `ruff.trace.server` set to its default value, no logs
from Ruff should appear.
After changing `ruff.trace.server` to either `messages` or `verbose`,
you should see log messages at `info` level or higher appear in Ruff's
output:
<img width="1005" alt="Screenshot 2024-06-10 at 10 35 04 AM"
src="6050d107-9815-4bd2-96d0-e86f096a57f5">
In Helix, by default, no logs from Ruff should appear.
To set the trace level in Helix, you'll need to modify your language
configuration as follows:
```toml
[language-server.ruff]
command = "/Users/jane/astral/ruff/target/debug/ruff"
args = ["server", "--preview"]
environment = { "RUFF_TRACE" = "messages" }
```
After doing this, logs of `info` level or higher should be visible in
Helix:
<img width="1216" alt="Screenshot 2024-06-10 at 10 39 26 AM"
src="8ff88692-d3f7-4fd1-941e-86fb338fcdcc">
You can use `:log-open` to quickly open the Helix log file.
In Neovim, by default, no logs from Ruff should appear.
To set the trace level in Neovim, you'll need to modify your
configuration as follows:
```lua
require('lspconfig').ruff.setup {
cmd = {"/path/to/debug/executable", "server", "--preview"},
cmd_env = { RUFF_TRACE = "messages" }
}
```
You should see logs appear in `:LspLog` that look like the following:
<img width="1490" alt="Screenshot 2024-06-11 at 11 24 01 AM"
src="576cd5fa-03cf-477a-b879-b29a9a1200ff">
You can adjust `logLevel` and `logFile` in `settings`:
```lua
require('lspconfig').ruff.setup {
cmd = {"/path/to/debug/executable", "server", "--preview"},
cmd_env = { RUFF_TRACE = "messages" },
settings = {
logLevel = "debug",
logFile = "your/log/file/path/log.txt"
}
}
```
The `logLevel` and `logFile` can also be set in Helix like so:
```toml
[language-server.ruff.config.settings]
logLevel = "debug"
logFile = "your/log/file/path/log.txt"
```
Even if this log file does not exist, it should now be created and
written to after running the server:

src="ab533cf7-d5ac-4178-97f1-e56da17450dd">
## Summary
Fixes https://github.com/astral-sh/ruff-vscode/issues/482.
I've made adjustments to `format` and `format_range` that handle parsing
errors before they become server errors. We'll still log this as a
problem, but there will no longer be a visible popup.
## Test Plan
Instead of seeing a visible error when formatting a document with syntax
issues, you should see this warning in the LSP logs:

src="9d68947d-6462-4ca6-ab5a-65e573c91db6">
Similarly, if you try to format a range with syntax issues, you should
see this warning in the LSP logs instead of a visible error popup:

## Summary
Closes https://github.com/astral-sh/ruff/issues/11587.
## Test Plan
- Added a lint error to `test_server.py` in `vscode-ruff`.
- Validated that, prior to this change, diagnostics appeared in the
file.
- Validated that, with this change, no diagnostics were shown.
- Validated that, with this change, no diagnostics were fixed on-save.
## Summary
Fixes#11516
`ruff server` was sending both regular source actions and notebook
source actions back when passed an empty action filter. This PR makes a
few small changes so that notebook source actions are not sent when
regular source actions are sent, which means that an empty filter will
only return regular source actions.
## Test Plan
I confirmed that duplicate code actions no longer appeared in Neovim,
using a configuration similar to the one from the original issue.

## Summary
Recent changes made in the [Jupyter Notebook feature
PR](https://github.com/astral-sh/ruff/pull/11206) caused automatic
configuration reloading to stop working. This was because we would check
for paths to reload using the changed path, when we should have been
using the parent path of the changed path (to get the directory it was
changed in).
Additionally, this PR fixes an issue where `ruff.toml` and `.ruff.toml`
files were not being automatically reloaded.
Finally, this PR improves configuration reloading by actively publishing
diagnostics for notebook documents (which won't be affected by the
workspace refresh since they don't use pull diagnostics). It will also
publish diagnostics for text documents if pull diagnostics aren't
supported.
## Test Plan
To test this, open an existing configuration file in a codebase, and
make modifications that will affect one or more open Python / Jupyter
Notebook files. You should observe that the diagnostics for both kinds
of files update automatically when the file changes are saved.
Here's a test video showing what a successful test should look like:

## Summary
Previously, `ruff.applyFormat`, seen in VS Code as the command `Ruff:
Format Document`, would only format the currently active notebook cell
inside a notebook document. This PR makes `ruff.applyFormat` format the
entire notebook document at once, operating on each code cell in order.
## Test Plan
1. Open a notebook document that has multiple unformatted code cells.
2. Run `Ruff: Format Document` through the Command Palette
(`Ctrl/Cmd+Shift+P` by default)
3. Observe that all code cells in the notebook have been formatted.
## Summary
Closes https://github.com/astral-sh/ruff/issues/10858.
`ruff server` now supports `*.ipynb` (aka Jupyter Notebook) files.
Extensive internal changes have been made to facilitate this, which I've
done some work to contextualize with documentation and an pre-review
that highlights notable sections of the code.
`*.ipynb` cells should behave similarly to `*.py` documents, with one
major exception. The format command `ruff.applyFormat` will only apply
to the currently selected notebook cell - if you want to format an
entire notebook document, use `Format Notebook` from the VS Code context
menu.
## Test Plan
The VS Code extension does not yet have Jupyter Notebook support
enabled, so you'll first need to enable it manually. To do this,
checkout the `pre-release` branch and modify `src/common/server.ts` as
follows:
Before:
After:
I recommend testing this PR with large, complicated notebook files. I
used notebook files from [this popular
repository](https://github.com/jakevdp/PythonDataScienceHandbook/tree/master/notebooks)
in my preliminary testing.
The main thing to test is ensuring that notebook cells behave the same
as Python documents, besides the aforementioned issue with
`ruff.applyFormat`. You should also test adding and deleting cells (in
particular, deleting all the code cells and ensure that doesn't break
anything), changing the kind of a cell (i.e. from markup -> code or vice
versa), and creating a new notebook file from scratch. Finally, you
should also test that source actions work as expected (and across the
entire notebook).
Note: `ruff.applyAutofix` and `ruff.applyOrganizeImports` are currently
broken for notebook files, and I suspect it has something to do with
https://github.com/astral-sh/ruff/issues/11248. Once this is fixed, I
will update the test plan accordingly.

## Summary
Fixes https://github.com/astral-sh/ruff/issues/10594.
Code actions to disable a diagnostic via `noqa` comment are now
available.
6d3bcf11-a9d9-499b-8c7f-a10cd39cfbba
`DiagnosticFix` has been changed so that `noqa` code actions appear even
for diagnostics with no available quick fix. It can contain quick fix
edits, `noqa` comment edits, or both.
## Test Plan
The scenarios that need to be tested are as follows:
* A code action to disable a diagnostic should be available for every
diagnostic.
* Using this code action should append to the appropriate line with the
diagnostic, or modify an existing `noqa` comment.
* Adding a `noqa` comment manually should make a diagnostic disappear
* `Fix all auto-fixable problems` should not add `noqa` comments
* Removing a code from a `noqa` comment should make the diagnostic
re-appear
## Summary
Fixes https://github.com/astral-sh/ruff/issues/11207.
The server would hang after handling a shutdown request on
`IoThreads::join()` because a global sender (`MESSENGER`, used to send
`window/showMessage` notifications) would remain allocated even after
the event loop finished, which kept the writer I/O thread channel open.
To fix this, I've made a few structural changes to `ruff server`. I've
wrapped the send/receive channels and thread join handle behind a new
struct, `Connection`, which facilitates message sending and receiving,
and also runs `IoThreads::join()` after the event loop finishes. To
control the number of sender channels, the `Connection` wraps the sender
channel in an `Arc` and only allows the creation of a wrapper type,
`ClientSender`, which hold a weak reference to this `Arc` instead of
direct channel access. The wrapper type implements the channel methods
directly to prevent access to the inner channel (which would allow the
channel to be cloned). ClientSender's function is analogous to
[`WeakSender` in
`tokio`](https://docs.rs/tokio/latest/tokio/sync/mpsc/struct.WeakSender.html).
Additionally, the receiver channel cannot be accessed directly - the
`Connection` only exposes an iterator over it.
These changes will guarantee that all channels are closed before the I/O
threads are joined.
## Test Plan
Repeatedly open and close an editor utilizing `ruff server` while
observing the task monitor. The net total amount of open `ruff`
instances should be zero once all editor windows have closed.
The following logs should also appear after the server is shut down:
<img width="835" alt="Screenshot 2024-04-30 at 3 56 22 PM"
src="404b74f5-ef08-4bb4-9fa2-72e72b946695">
This can be tested on VS Code by changing the settings and then checking
`Output`.
## Summary
Fixes#11185Fixes#11214
Document path and package information is now forwarded to the Ruff
linter, which allows `per-file-ignores` to correctly match against the
file name. This also fixes an issue where the import sorting rule didn't
distinguish between third-party and first-party packages since we didn't
pass in the package root.
## Test Plan
`per-file-ignores` should ignore files as expected. One quick way to
check is by adding this to your `pyproject.toml`:
```toml
[tool.ruff.lint.per-file-ignores]
"__init__.py" = ["ALL"]
```
Then, confirm that no diagnostics appear when you add code to an
`__init__.py` file (besides syntax errors).
The import sorting fix can be verified by failing to reproduce the
original issue - an `I001` diagnostic should not appear in
`other_module.py`.
## Summary
Fixes#11114.
As part of the `onClose` handler, we publish an empty array of
diagnostics for the document being closed, similar to
[`ruff-lsp`](187d7790be/ruff_lsp/server.py (L459-L464)).
This prevent phantom diagnostics from lingering after a document is
closed. We'll only do this if the client doesn't support pull
diagnostics, because otherwise clearing diagnostics is their
responsibility.
## Test Plan
Diagnostics should no longer appear for a document in the Problems tab
after the document is closed.

## Summary
Add support for hover menu to ruff_server, as requested in
[10595](https://github.com/astral-sh/ruff/issues/10595).
Majority of new code is in hover.rs.
I reused the regex from ruff-lsp's implementation. Also reused the
format_rule_text function from ruff/src/commands/rule.rs
Added capability registration in server.rs, and added the handler to
api.rs.
## Test Plan
Tested in NVIM v0.10.0-dev-2582+g2a8cef6bd, configured with lspconfig
using the default options (other than cmd pointing to my test build,
with options "server" and "--preview"). OS: Ubuntu 24.04, kernel
6.8.0-22.

## Summary
This is a follow-up to https://github.com/astral-sh/ruff/pull/10984 that
implements configuration resolution for editor configuration. By 'editor
configuration', I'm referring to the client settings that correspond to
Ruff configuration/options, like `preview`, `select`, and so on. These
will be combined with 'project configuration' (configuration taken from
project files such as `pyproject.toml`) to generate the final linter and
formatter settings used by `RuffSettings`. Editor configuration takes
priority over project configuration.
In a follow-up pull request, I'll implement a new client setting that
allows project configuration to override editor configuration, as per
[this issue](https://github.com/astral-sh/ruff-vscode/issues/425).
## Review guide
The first commit, e38966d8843becc7234fa7d46009c16af4ba41e9, is just
doing re-arrangement so that we can pass the right things to
`RuffSettings::resolve`. The actual resolution logic is in the second
commit, 0eec9ee75c10e5ec423bd9f5ce1764f4d7a5ad86. It might help to look
at these comments individually since the diff is rather messy.
## Test Plan
For the settings to show up in VS Code, you'll need to checkout this
branch: https://github.com/astral-sh/ruff-vscode/pull/456.
To test that the resolution for a specific setting works as expected,
run through the following scenarios, setting it in project and editor
configuration as needed:
| Set in project configuration? | Set in editor configuration? |
Expected Outcome |
|-------------------------------|--------------------------------------------------|------------------------------------------------------------------------------------------|
| No | No | The editor should behave as if the setting was set to its
default value. |
| Yes | No | The editor should behave as if the setting was set to the
value in project configuration. |
| No | Yes | The editor should behave as if the setting was set to the
value in editor configuration. |
| Yes | Yes (but distinctive from project configuration) | The editor
should behave as if the setting was set to the value in editor
configuration. |
An exception to this is `extendSelect`, which does not have an analog in
TOML configuration. Instead, you should verify that `extendSelect`
amends the `select` setting. If `select` is set in both editor and
project configuration, `extendSelect` will only append to the `select`
value in editor configuration, so make sure to un-set it there if you're
testing `extendSelect` with `select` in project configuration.
## Summary
Fixes#11059
Several major editors don't support [pull
diagnostics](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_pullDiagnostics),
a method of sending diagnostics to the client that was introduced in
version `0.3.17` of the specification. Until now, `ruff server` has only
used pull diagnostics, which resulted in diagnostics not being available
on Neovim and Helix, which don't support pull diagnostics yet (though
Neovim `10.0` will have support for this).
`ruff server` will now utilize the older method of sending diagnostics,
known as 'publish diagnostics', when pull diagnostics aren't supported
by the client. This involves re-linting a document every time it is
opened or modified, and then sending the diagnostics generated from that
lint to the client via the `textDocument/publishDiagnostics`
notification.
## Test Plan
The easiest way to test that this PR works is to check if diagnostics
show up on Neovim `<=0.9`.
## Summary
The server now requests a [workspace diagnostic
refresh](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#diagnostic_refresh)
when a configuration file gets changed. This means that diagnostics for
all open files will be automatically re-requested by the client on a
config change.
## Test Plan
You can test this by opening several files in VS Code, setting `select`
in your file configuration to `[]`, and observing that the diagnostics
go away once the file is saved (besides any `Pylance` diagnostics).
Restore it to what it was before, and you should see the diagnostics
automatically return once a save happens.
## Summary
Fixes#10866.
Introduces the `show_err_msg!` macro which will send a message to be
shown as a popup to the client via the `window/showMessage` LSP method.
## Test Plan
Insert various `show_err_msg!` calls in common code paths (for example,
at the beginning of `event_loop`) and confirm that these messages appear
in your editor.
To test that panicking works correctly, add this to the top of the `fn
run` definition in
`crates/ruff_server/src/server/api/requests/execute_command.rs`:
```rust
panic!("This should appear");
```
Then, try running a command like `Ruff: Format document` from the
command palette (`Ctrl/Cmd+Shift+P`). You should see the following
messages appear:
## Summary
Fixes#10780.
The server now send code actions to the client with a Ruff-specific
kind, `source.*.ruff`. The kind filtering logic has also been reworked
to support this.
## Test Plan
Add this to your `settings.json` in VS Code:
```json
{
"[python]": {
"editor.codeActionsOnSave": {
"source.organizeImports.ruff": "explicit",
},
}
}
```
Imports should be automatically organized when you manually save with
`Ctrl/Cmd+S`.
## Summary
Configuration is no longer the property of a workspace but rather of
individual documents. Just like the Ruff CLI, each document is
configured based on the 'nearest' project configuration. See [the Ruff
documentation](https://docs.astral.sh/ruff/configuration/#config-file-discovery)
for more details.
To reduce the amount of times we resolve configuration for a file, we
have an index for each workspace that stores a reference-counted pointer
to a configuration for a given folder. If another file in the same
folder is opened, the configuration is simply re-used rather than us
re-resolving it.
## Guide for reviewing
The first commit is just the restructuring work, which adds some noise
to the diff. If you want to quickly understand what's actually changed,
I recommend looking at the two commits that come after it.
f7c073d441 makes configuration a property
of `DocumentController`/`DocumentRef`, moving it out of `Workspace`, and
it also sets up the `ConfigurationIndex`, though it doesn't implement
its key function, `get_or_insert`. In the commit after it,
fc35618f17, we implement `get_or_insert`.
## Test Plan
The best way to test this would be to ensure that the behavior matches
the Ruff CLI. Open a project with multiple configuration files (or add
them yourself), and then introduce problems in certain files that won't
show due to their configuration. Add those same problems to a section of
the project where those rules are run. Confirm that the lint rules are
run as expected with `ruff check`. Then, open your editor and confirm
that the diagnostics shown match the CLI output.
As an example - I have a workspace with two separate folders, `pandas`
and `scipy`. I created a `pyproject.toml` file in `pandas/pandas/io` and
a `ruff.toml` file in `pandas/pandas/api`. I changed the `select` and
`preview` settings in the sub-folder configuration files and confirmed
that these were reflected in the diagnostics. I also confirmed that this
did not change the diagnostics for the `scipy` folder whatsoever.
## Summary
This is a follow-up to https://github.com/astral-sh/ruff/pull/10764.
Support for diagnostics, quick fixes, and source actions can now be
disabled via client settings.
## Test Plan
### Manual Testing
Set up your workspace as described in the test plan in
https://github.com/astral-sh/ruff/pull/10764, up to step 2. You don't
need to add a debug statement.
The configuration for `folder_a` and `folder_b` should be as follows:
`folder_a`:
```json
{
"ruff.codeAction.fixViolation": {
"enable": true
}
}
```
`folder_b`
```json
{
"ruff.codeAction.fixViolation": {
"enable": false
}
}
```
Finally, open up your VS Code User Settings and un-check the `Ruff > Fix
All` setting.
1. Open a Python file in `folder_a` that has existing problems. The
problems should be highlighted, and quick fix should be available.
`source.fixAll` should not be available as a source action.
2. Open a Python file in `folder_b` that has existing problems. The
problems should be highlighted, but quick fixes should not be available
for any of them. `source.fixAll` should not be available as a source
action.
3. Open up your VS Code Workspace Settings (second tab under the search
bar) and un-check `Ruff > Lint: Enable`
4. Both files you tested in steps 1 and 2 should now lack any visible
diagnostics. `source.organizeImports` should still be available as a
source action.
## Summary
This builds off of the work in
https://github.com/astral-sh/ruff/pull/10652 to implement a command
executor, backwards compatible with the commands from the previous LSP
(`ruff.applyAutofix`, `ruff.applyFormat` and
`ruff.applyOrganizeImports`).
This involved a lot of refactoring and tweaks to the code action
resolution code - the most notable change is that workspace edits are
specified in a slightly different way, using the more general `changes`
field instead of the `document_changes` field (which isn't supported on
all LSP clients). Additionally, the API for synchronous request handlers
has been updated to include access to the `Requester`, which we use to
send a `workspace/applyEdit` request to the client.
## Test Plan
7932e30f-d944-4e35-b828-1d81aa56c087
## Summary
This builds on top of the work in
https://github.com/astral-sh/ruff/pull/10597 to support `Ruff: Organize
imports` as an available source action.
To do this, we have to support `Clone`-ing for linter settings, since we
need to modify them in place to select import-related diagnostics
specifically (`I001` and `I002`).
## Test Plan
04282d01-dfda-4ac5-aa8f-6a92d5f85bfd
## Summary
`ruff server` now has source action `source.fixAll` as an available code
action.
This also fixes https://github.com/astral-sh/ruff/issues/10593 in the
process of revising the code for quick fix code actions.
## Test Plan
f4c07425-e68a-445f-a4ed-949c9197a6be
## Summary
Fixes#10618.
This PR introduces a proper API for sending requests to the client and
handling any response sent back. Dynamic capability registration now
uses this new API, fixing an issue where a much more simplistic response
handler silently flushes a code action request that needed a response.
## Test Plan
#10618 can no longer be reproduced. No errors about unhandled responses
should appear in the extension output, and you should see this new log
when the server starts:
```
<DATE> <TIME> [info] <DURATION> INFO ruff_server::server Configuration file watcher successfully registered
```
## Summary
Fixes#10366.
`ruff server` now registers a file watcher on the client side using the
LSP protocol, and listen for events on configuration files. On such an
event, it reloads the configuration in the 'nearest' workspace to the
file that was changed.
## Test Plan
N/A
## Summary
I used `codespell` and `gramma` to identify mispellings and grammar
errors throughout the codebase and fixed them. I tried not to make any
controversial changes, but feel free to revert as you see fit.

## Summary
This PR introduces the `ruff_server` crate and a new `ruff server`
command. `ruff_server` is a re-implementation of
[`ruff-lsp`](https://github.com/astral-sh/ruff-lsp), written entirely in
Rust. It brings significant performance improvements, much tighter
integration with Ruff, a foundation for supporting entirely new language
server features, and more!
This PR is an early version of `ruff_lsp` that we're calling the
**pre-release** version. Anyone is more than welcome to use it and
submit bug reports for any issues they encounter - we'll have some
documentation on how to set it up with a few common editors, and we'll
also provide a pre-release VSCode extension for those interested.
This pre-release version supports:
- **Diagnostics for `.py` files**
- **Quick fixes**
- **Full-file formatting**
- **Range formatting**
- **Multiple workspace folders**
- **Automatic linter/formatter configuration** - taken from any
`pyproject.toml` files in the workspace.
Many thanks to @MichaReiser for his [proof-of-concept
work](https://github.com/astral-sh/ruff/pull/7262), which was important
groundwork for making this PR possible.
## Architectural Decisions
I've made an executive choice to go with `lsp-server` as a base
framework for the LSP, in favor of `tower-lsp`. There were several
reasons for this:
1. I would like to avoid `async` in our implementation. LSPs are mostly
computationally bound rather than I/O bound, and `async` adds a lot of
complexity to the API, while also making harder to reason about
execution order. This leads into the second reason, which is...
2. Any handlers that mutate state should be blocking and run in the
event loop, and the state should be lock-free. This is the approach that
`rust-analyzer` uses (also with the `lsp-server`/`lsp-types` crates as a
framework), and it gives us assurances about data mutation and execution
order. `tower-lsp` doesn't support this, which has caused some
[issues](https://github.com/ebkalderon/tower-lsp/issues/284) around data
races and out-of-order handler execution.
3. In general, I think it makes sense to have tight control over
scheduling and the specifics of our implementation, in exchange for a
slightly higher up-front cost of writing it ourselves. We'll be able to
fine-tune it to our needs and support future LSP features without
depending on an upstream maintainer.
## Test Plan
The pre-release of `ruff_server` will have snapshot tests for common
document editing scenarios. An expanded test suite is on the roadmap for
future version of `ruff_server`.
