Closes https://github.com/astral-sh/ruff/issues/8076
Follow-up to #8358
Doubles the amount of ecosystem checks we do, adding separate groups for
the stable sections.
We're likely to run into GitHub comment length restrictions if there are
significant deviations. However, it should not be common for changes in
stable and preview to occur at the same time, nor should it be common
for linter and formatter changes to occur at the same time.
Extends https://github.com/astral-sh/ruff/pull/8416 activating the
`black-and-ruff` and `black-then-ruff` formatter comparison modes for
ecosystem checks allowing us to compare changes to Black across the
ecosystem.
Previously, the ecosystem checks formatted with the baseline then
formatted again with `--diff` to get the changed files.
Now, the ecosystem checks support a new mode where we:
- Format with the baseline
- Commit the changes
- Reset to the target ref
- Format again
- Check the diff from the baseline commit
This effectively tests Ruff changes on unformatted code rather than
changes in previously formatted code (unless, of course, the project is
already using Ruff).
While this mode is the new default, I've retained the old one for local
checks. The mode can be toggled with `--format-comparison <type>`.
Includes some more aggressive resetting of the GitHub repositories when
cached.
Here, I've also stubbed comparison modes in which `black` is used as the
baseline. While these do nothing here, #8419 adds support.
I tested this with the commit from #8216 and ecosystem changes appear
https://gist.github.com/zanieb/a982ec8c392939043613267474471a6e
Requiring `cargo build` per commit is way too slow. Instead, we use the
production Ruff version. Additionally, Black is replaced with the Ruff
formatter.
**Summary** Simplify CI by ensuring that the source distribution is
always built with the rust version that has been explicitly tested. See
discussion in #8389Closes#8389

Until https://github.com/astral-sh/ruff/issues/8076 is ready, it seems
beneficial to get feedback on preview mode changes.
Tested locally, updated logs to output the flags passed to `ruff` and
verified `--preview` is used.
## Summary
We typically avoid enforcing exclusions if a file was passed to Ruff
directly on the CLI. However, we also allow `--force-exclude`, which
ignores excluded files _even_ if they're passed to Ruff directly. This
is really important for pre-commit, which always passes changed files --
we need to exclude files passed by pre-commit if they're in the
`exclude` lists.
Turns out the new `lint.exclude` and `format.exclude` settings weren't
respecting `--force-exclude`.
Closes https://github.com/astral-sh/ruff/issues/8391.
## Summary
By using `set`, we were setting the bracket flag to `false` if another
operator was visited.
Closes https://github.com/astral-sh/ruff/issues/8379.
## Test Plan
`cargo test`
## Summary
This PR adds a new `LiteralExpressionRef` which wraps all of the literal
expression nodes in a single enum. This allows for a narrow type when
working exclusively with a literal node. Additionally, it also
implements a `Expr::as_literal_expr` method to return the new enum if
the expression is indeed a literal one.
A few rules have been updated to account for the new enum:
1. `redundant_literal_union`
2. `if_else_block_instead_of_dict_lookup`
3. `magic_value_comparison`
To account for the change in (2), a new `ComparableLiteral` has been
added which can be constructed from the new enum
(`ComparableLiteral::from(<LiteralExpressionRef>)`).
### Open Questions
1. The new `ComparableLiteral` can be exclusively used via the
`LiteralExpressionRef` enum. Should we remove all of the literal
variants from `ComparableExpr` and instead have a single
`ComparableExpr::Literal(ComparableLiteral)` variant instead?
## Test Plan
`cargo test`
This PR updates the editor integration section of the documentation for
Neovim.
* Removes the now archived `null-ls` plugin
* Add `nvim-lint` (for linters) and `conform.nvim` (for formatter)
plugins

## Summary
We were considering the `{` within an f-string to be a left brace, which
caused the "space-after-colon" rule to trigger incorrectly.
Closes https://github.com/astral-sh/ruff/issues/8299.
## Summary
Uses `warn_user_once!` instead of `warn!` to ensure that every warning
is shown exactly once, regardless of whether there are duplicates in the
list, or warnings that are raised by multiple configuration files.
Closes#8271.
## Summary
If the value of `shell` wasn't literally `True`, we now show a message
describing it as truthy, rather than the (misleading) `shell=True`
literal in the diagnostic.
Closes https://github.com/astral-sh/ruff/issues/8310.
**Summary** Previously, own line comment following after a docstring
followed by newline(s) before the first content statement were treated
as trailing on the docstring and we didn't insert a newline after the
docstring as black would.
Before:
```python
class ModuleBrowser:
"""Browse module classes and functions in IDLE."""
# This class is also the base class for pathbrowser.PathBrowser.
def __init__(self, master, path, *, _htest=False, _utest=False):
pass
```
After:
```python
class ModuleBrowser:
"""Browse module classes and functions in IDLE."""
# This class is also the base class for pathbrowser.PathBrowser.
def __init__(self, master, path, *, _htest=False, _utest=False):
pass
```
I'm not entirely happy about hijacking
`handle_own_line_comment_between_statements`, but i don't know a better
spot to put it.
Fixes#7948
**Test Plan** Fixtures
We previously incorrectly treated byte strings in docstring position as
docstrings because black does so
(https://github.com/astral-sh/ruff/pull/8283#discussion_r1375682931,
https://github.com/psf/black/issues/4002), even CPython doesn't
recognize them:
```console
$ python3.12
Python 3.12.0 (main, Oct 6 2023, 17:57:44) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

## Summary
This PR adds `Default` for the following literal nodes:
* `StringLiteral`
* `BytesLiteral`
* `BooleanLiteral`
* `NoneLiteral`
* `EllipsisLiteral`
The implementation creates the zero value of the respective literal
nodes in terms of the Python language.
## Test Plan
`cargo test`
## Summary
This PR inlines the formatting logic for `ExprNumberLiteral` and removes
the need of having dedicated `Format*` struct for each number type.
## Test Plan
`cargo test`
## Summary
This PR splits the `Constant` enum as individual literal nodes. It
introduces the following new nodes for each variant:
* `ExprStringLiteral`
* `ExprBytesLiteral`
* `ExprNumberLiteral`
* `ExprBooleanLiteral`
* `ExprNoneLiteral`
* `ExprEllipsisLiteral`
The main motivation behind this refactor is to introduce the new AST
node for implicit string concatenation in the coming PR. The elements of
that node will be either a string literal, bytes literal or a f-string
which can be implemented using an enum. This means that a string or
bytes literal cannot be represented by `Constant::Str` /
`Constant::Bytes` which creates an inconsistency.
This PR avoids that inconsistency by splitting the constant nodes into
it's own literal nodes, literal being the more appropriate naming
convention from a static analysis tool perspective.
This also makes working with literals in the linter and formatter much
more ergonomic like, for example, if one would want to check if this is
a string literal, it can be done easily using
`Expr::is_string_literal_expr` or matching against `Expr::StringLiteral`
as oppose to matching against the `ExprConstant` and enum `Constant`. A
few AST helper methods can be simplified as well which will be done in a
follow-up PR.
This introduces a new `Expr::is_literal_expr` method which is the same
as `Expr::is_constant_expr`. There are also intermediary changes related
to implicit string concatenation which are quiet less. This is done so
as to avoid having a huge PR which this already is.
## Test Plan
1. Verify and update all of the existing snapshots (parser, visitor)
2. Verify that the ecosystem check output remains **unchanged** for both
the linter and formatter

## Summary
This PR adds a new `Singleton` enum for the `PatternMatchSingleton`
node.
Earlier the node was using the `Constant` enum but the value for this
pattern can only be either `None`, `True` or `False`. With the coming PR
to remove the `Constant`, this node required a new type to fill in.
This also has the benefit of narrowing the type down to only the
possible values for the node as evident by the removal of `unreachable`.
## Test Plan
Update the AST snapshots and run `cargo test`.
## Summary
Refactor for isort implementation. Closes#7738.
I introduced a `NatOrdString` and a `NatOrdStr` type to have a naturally
ordered `String` and `&str`, and I pretty much went back to the original
implementation based on `module_key`, `member_key` and
`sorted_by_cached_key` from itertools. I tried my best to avoid
unnecessary allocations but it may have been clumsy in some places, so
feedback is appreciated! I also renamed the `Prefix` enum to
`MemberType` (and made some related adjustments) because I think this
fits more what it is, and it's closer to the wording found in the isort
documentation.
I think the result is nicer to work with, and it should make
implementing #1567 and the like easier :)
Of course, I am very much open to any and all remarks on what I did!
## Test Plan
I didn't add any test, I am relying on the existing tests since this is
just a refactor.
