This commit removes rule redirects such as ("U" -> "UP") from the
RuleCodePrefix enum because they complicated the generation of that enum
(which we want to change to be prefix-agnostic in the future).
To preserve backwards compatibility redirects are now resolved
before the strum-generated RuleCodePrefix::from_str is invoked.
This change also brings two other advantages:
* Redirects are now only defined once
(previously they had to be defined twice:
once in ruff_macros/src/rule_code_prefix.rs
and a second time in src/registry.rs).
* The deprecated redirects will no longer be suggested in IDE
autocompletion within pyproject.toml since they are now no
longer part of the ruff.schema.json.
Yet another refactor to let us implement the many-to-many mapping
between codes and rules in a prefix-agnostic way.
We want to break up the RuleCodePrefix[1] enum into smaller enums.
To facilitate that this commit introduces a new wrapping type around
RuleCodePrefix so that we can start breaking it apart.
[1]: Actually `RuleCodePrefix` is the previous name of the autogenerated
enum ... I renamed it in b19258a243 to
RuleSelector since `ALL` isn't a prefix. This commit now renames it back
but only because the new `RuleSelector` wrapper type, introduced in this
commit, will let us move the `ALL` variant from `RuleCodePrefix` to
`RuleSelector` in the next commit.
At present, `ISC001` and `ISC002` flag concatenations like the following:
```py
"a" "b" # ISC001
"a" \
"b" # ISC002
```
However, multiline concatenations are allowed.
This PR adds a setting:
```toml
[tool.ruff.flake8-implicit-str-concat]
allow-multiline = false
```
Which extends `ISC002` to _also_ flag multiline concatenations, like:
```py
(
"a" # ISC002
"b"
)
```
Note that this is backwards compatible, as `allow-multiline` defaults to `true`.
Ruff supports more than `known-first-party`, `known-third-party`, `extra-standard-library`, and `src` nowadays.
Not sure if this is the best wording. Suggestions welcome!
Extend test fixture to verify the targeting.
Includes two "attribute docstrings" which per PEP 257 are not recognized by the Python bytecode compiler or available as runtime object attributes. They are not available for us either at time of writing, but include them for completeness anyway in case they one day are.
