ดาวน์โหลด Ruff 0.12.0

Check out the blog post for a migration
guide and overview of the changes!

Breaking changes
- Detection of more syntax errors

Ruff now detects version-related syntax errors, such as the use of the `match`
statement on Python versions before 3.10, and syntax errors emitted by
CPython's compiler, such as irrefutable `match` patterns before the final
`case` arm.

- New default Python version handling for syntax errors

Ruff will default to the _latest_ supported Python version (3.13) when
checking for the version-related syntax errors mentioned above to prevent
false positives in projects without a Python version configured. The default
in all other cases, like applying lint rules, is unchanged and remains at the
minimum supported Python version (3.9).

- Updated f-string formatting

Ruff now formats multi-line f-strings with format specifiers to avoid adding a
line break after the format specifier. This addresses a change to the Python
grammar in version 3.13.4 that made such a line break a syntax error.

- **`rust-toolchain.toml` is no longer included in source distributions**

The `rust-toolchain.toml` is used to specify a higher Rust version than Ruff's
minimum supported Rust version (MSRV) for development and building release
artifacts. However, when present in source distributions, it would also cause
downstream package maintainers to pull in the same Rust toolchain, even if
their available toolchain was MSRV-compatible.

Removed Rules
The following rules have been removed:

- `suspicious-xmle-tree-usage`
(S320)

Deprecated Rules
The following rules have been deprecated:

- `pandas-df-variable-name`

Stabilization
The following rules have been stabilized and are no longer in preview:

- `for-loop-writes` (FURB122)
- `check-and-remove-from-set` (FURB132)
- `verbose-decimal-constructor` (FURB157)
- `fromisoformat-replace-z` (FURB162)
- `int-on-sliced-str` (FURB166)
- `exc-info-outside-except-handler` (LOG014)
- `import-outside-top-level` (PLC0415)
- `unnecessary-dict-index-lookup` (PLR1733)
- `nan-comparison` (PLW0177)
- `eq-without-hash` (PLW1641)
- `pytest-parameter-with-default-argument` (PT028)
- `pytest-warns-too-broad` (PT030)
- `pytest-warns-with-multiple-statements` (PT031)
- `invalid-formatter-suppression-comment` (RUF028)
- `dataclass-enum` (RUF049)
- `class-with-mixed-type-vars` (RUF053)
- `unnecessary-round` (RUF057)
- `starmap-zip` (RUF058)
- `non-pep604-annotation-optional` (UP045)
- `non-pep695-generic-class` (UP046)
- `non-pep695-generic-function` (UP047)
- `private-type-parameter` (UP049)

The following behaviors have been stabilized:

- [`collection-literal-concatenation`] (RUF005) now recognizes slices, in
addition to list literals and variables.
- The fix for [`readlines-in-for`] (FURB129) is now marked as always safe.
- [`if-else-block-instead-of-if-exp`] (SIM108) will now further simplify
expressions to use `or` instead of an `if` expression, where possible.
- [`unused-noqa`] (RUF100) now checks for file-level `noqa` comments as well
as inline comments.
- [`subprocess-without-shell-equals-true`] (S603) now accepts literal strings,
as well as lists and tuples of literal strings, as trusted input.
- [`boolean-type-hint-positional-argument`] (FBT001) now applies to types that
include `bool`, like `bool | int` or `typing.Optional[bool]`, in addition to
plain `bool` annotations.
- [`non-pep604-annotation-union`] (UP007) has now been split into two rules.
UP007 now applies only to `typing.Union`, while
[`non-pep604-annotation-optional`] (UP045) checks for use of
`typing.Optional`. UP045 has also been stabilized in this release, but you
may need to update existing `include`, `ignore`, or `noqa` settings to
accommodate this change.
