## Summary
This PR adds support for named expressions when analyzing `__all__`
assignments, as per https://github.com/astral-sh/ruff/issues/7672. It
also loosens the enforcement around assignments like: `__all__ =
list(some_other_expression)`. We shouldn't flag these as invalid, even
though we can't analyze the members, since we _know_ they evaluate to a
`list`.
Closes https://github.com/astral-sh/ruff/issues/7672.
## Test Plan
`cargo test`
## Summary
Per the discussion in
https://github.com/astral-sh/ruff/discussions/6183, this PR adds an
`implicit_concatenated` flag to the string and bytes constant variants.
It's not actually _used_ anywhere as of this PR, but it is covered by
the tests.
Specifically, we now use a struct for the string and bytes cases, along
with the `Expr::FString` node. That struct holds the value, plus the
flag:
```rust
#[derive(Clone, Debug, PartialEq, is_macro::Is)]
pub enum Constant {
Str(StringConstant),
Bytes(BytesConstant),
...
}
#[derive(Clone, Debug, PartialEq, Eq)]
pub struct StringConstant {
/// The string value as resolved by the parser (i.e., without quotes, or escape sequences, or
/// implicit concatenations).
pub value: String,
/// Whether the string contains multiple string tokens that were implicitly concatenated.
pub implicit_concatenated: bool,
}
impl Deref for StringConstant {
type Target = str;
fn deref(&self) -> &Self::Target {
self.value.as_str()
}
}
#[derive(Clone, Debug, PartialEq, Eq)]
pub struct BytesConstant {
/// The bytes value as resolved by the parser (i.e., without quotes, or escape sequences, or
/// implicit concatenations).
pub value: Vec<u8>,
/// Whether the string contains multiple string tokens that were implicitly concatenated.
pub implicit_concatenated: bool,
}
impl Deref for BytesConstant {
type Target = [u8];
fn deref(&self) -> &Self::Target {
self.value.as_slice()
}
}
```
## Test Plan
`cargo test`
## Summary
This PR adds a new `Arguments` AST node, which we can use for function
calls and class definitions.
The `Arguments` node spans from the left (open) to right (close)
parentheses inclusive.
In the case of classes, the `Arguments` is an option, to differentiate
between:
```python
# None
class C: ...
# Some, with empty vectors
class C(): ...
```
In this PR, we don't really leverage this change (except that a few
rules get much simpler, since we don't need to lex to find the start and
end ranges of the parentheses, e.g.,
`crates/ruff/src/rules/pyupgrade/rules/lru_cache_without_parameters.rs`,
`crates/ruff/src/rules/pyupgrade/rules/unnecessary_class_parentheses.rs`).
In future PRs, this will be especially helpful for the formatter, since
we can track comments enclosed on the node itself.
## Test Plan
`cargo test`
## Summary
This PR moves two rules (`invalid-all-format` and `invalid-all-object`)
out of the name-binding phase, and into the dedicated pass over all
bindings that occurs at the end of the `Checker`. This is part of my
continued quest to separate the semantic model-building logic from the
actual rule enforcement.
