## Summary
Give red-knot the ability to infer int literal types. This is quick and
easy, mostly because these types are a convenient way to observe
control-flow handling with simple assignments.
## Test Plan
Added test.
## Summary
- Ever since https://github.com/godotengine/godot/pull/90457 was merged
into the `master` branch, Godot has been using ruff for linting and
formatting Python files. As such, this PR adds Godot to the "Who's Using
Ruff?" section of the main `README.md` file.
## Test Plan
- N/A
## Summary
In the [roadmap for `ruff
server`](https://github.com/astral-sh/ruff/discussions/10581) support
for vim and kate is listed. Therefore I added setup guides for them
based on the neovim guide. As I don't use pyright I wasn't able to
translate the corresponding part from the neovim guide.
## Test Plan
Doesn't apply.
* Potentially resolves#11619 (nondeterministic hashmap order across
different architectures) in F401 by replacing a hashmap with
nondeterministic traversal order with an ordered mapping.
I'm not sure how to test this with our CI/CD. I don't have an s390x
machine at home. Should I try it in Qemu?
## Summary
In an `__init__.py` file, it's not uncommon to lack a logical indent
(since it may just contain imports). In such cases, we were always
falling back to four-space indent. This PR adds detection for indents
within import groups.
Closes https://github.com/astral-sh/ruff/issues/11606.
## Summary
This PR aims to close#10095 by adding an option
`init-allow-undef-export` to the `pyflakes` settings. This option is
currently set to `true` such that behavior is kept identical.
But setting this option to `false` will lead to `F822` warnings to be
shown in all files, **including** `__init__.py` files.
As I've mentioned on #10095, I think `init-allow-undef-export=false`
would be the more user-friendly default option, as it creates fewer
surprises. @charliermarsh what do you think about making that the
default?
With this option in place, it's a single line fix for people that rely
on the old behavior.
And thinking longer term, for future major releases, one could probably
consider deprecating the option and eventually having people just `noqa`
these warnings if they are not wanted.
## Test Plan
I've added a `test_init_f822_enabled` test which repeats the test that
is done in the `init` test but this time with
`init-allow-undef-export=false` and the snap file correctly shows that
ruff will then trigger the otherwise suppressed F822 warning.
closes#10095
## Summary
Removed stray space in sample code snippet that is against ruff's own
default formatting rules.
This documentation appears on
https://docs.astral.sh/ruff/rules/unused-import/
## Test Plan
This is a trivially obvious change, verifiable with `ruff format
--check`
## 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
- Implements `Y066` from `flake8-pyi` as `PYI066`
- Fixes `PYI006` not being raised for `elif` clauses. This would have
conflicted with PYI006's implementation, so decided to do it in the same
PR.
## Test Plan
`cargo test` / `cargo insta review`
* Add a module type, `ModuleTypeId`
* Add an attribute lookup method `get_member` for `Type`
* Only implemented for `ModuleTypeId` and `ClassTypeId`
* [x] Should this be a trait?
*Answer: no*
* [x] Uses `unwrap`, but we should remove that. Maybe add a new variant
to `QueryError`?
*Answer: Return `Option<Type>` as is done elsewhere*
* Add `infer_definition_type` case for `Import`
* Add `infer_expr_type` case for `Attribute`
* Add a test to exercise these
* [x] remove all NOTE/FIXME/TODO after discussing with reviewers
## Summary
This PR ensures that if a variable is bound via `global`, and then the
`global` is read, the originating variable is also marked as read. It's
not perfect, in that it won't detect _rebindings_, like:
```python
from app import redis_connection
def func():
global redis_connection
redis_connection = 1
redis_connection()
```
So, above, `redis_connection` is still marked as unused.
But it does avoid flagging `redis_connection` as unused in:
```python
from app import redis_connection
def func():
global redis_connection
redis_connection()
```
Closes https://github.com/astral-sh/ruff/issues/11518.
## Summary
Follow up to https://github.com/astral-sh/ruff/pull/11521
Removes the extra added complexity for catch all match cases. This
matches the implementation of plain `else` statements.
## Test Plan
Added new test cases.

## Summary
Right now, we're discovering configuration files even within (e.g.)
virtual environments, because we're recursing without respecting the
`exclude` field on parent configuration.
Closes https://github.com/astral-sh/ruff-vscode/issues/478.
## Test Plan
Installed Pandas; verified that I saw no warnings:
## Summary
This PR fixes the bug to avoid flattening the global-only settings for
the new server.
This was added in https://github.com/astral-sh/ruff/pull/11497, possibly
to correctly de-serialize an empty value (`{}`). But, this lead to a bug
where the configuration under the `settings` key was not being read for
global-only variant.
By using #[serde(default)], we ensure that the settings field in the
`GlobalOnly` variant is optional and that an empty JSON object `{}` is
correctly deserialized into `GlobalOnly` with a default `ClientSettings`
instance.
fixes: #11507
## Test Plan
Update the snapshot and existing test case. Also, verify the following
settings in Neovim:
1. Nothing
```lua
ruff = {
cmd = {
'/Users/dhruv/work/astral/ruff/target/debug/ruff',
'server',
'--preview',
},
}
```
2. Empty dictionary
```lua
ruff = {
cmd = {
'/Users/dhruv/work/astral/ruff/target/debug/ruff',
'server',
'--preview',
},
init_options = vim.empty_dict(),
}
```
3. Empty `settings`
```lua
ruff = {
cmd = {
'/Users/dhruv/work/astral/ruff/target/debug/ruff',
'server',
'--preview',
},
init_options = {
settings = vim.empty_dict(),
},
}
```
4. With some configuration:
```lua
ruff = {
cmd = {
'/Users/dhruv/work/astral/ruff/target/debug/ruff',
'server',
'--preview',
},
init_options = {
settings = {
configuration = '/tmp/ruff-repro/pyproject.toml',
},
},
}
```
## Summary
This PR brings back the functionality to remove empty strings when
converting to an f-string in `UP032`.
For context, https://github.com/astral-sh/ruff/pull/8712 added this
functionality to remove _trailing_ empty strings but it got removed in
https://github.com/astral-sh/ruff/pull/8697 possibly unexpectedly so.
There's one difference which is that this PR will remove _any_ empty
strings and not just trailing ones. For example,

(

- ""

```
## Test Plan
Run `cargo insta test` and update the snapshots.
