Previously Linter::parse_code("E401") returned
(Linter::Pycodestyle, "401") ... after this commit it returns
(Linter::Pycodestyle, "E401") instead, which is important
for the future implementation of the many-to-many mapping.
(The second value of the tuple isn't used currently.)
Fairly mechanical. Did a few of the simple cases manually to make sure things were working, and I think the rest will be easily achievable via a quick `fastmod` command.
ref #1871
I think we've never run into this case, since it's rare to import `*` from a module _and_ import some other member explicitly. But we were deviating from `isort` by placing the `*` after other members, rather than up-top.
Closes#2318.
`RUF100` does not take into account a rule ignored for a file via a `per-file-ignores` configuration. To see this, try the following pyproject.toml:
```toml
[tool.ruff.per-file-ignores]
"test.py" = ["F401"]
```
and this test.py file:
```python
import itertools # noqa: F401
```
Running `ruff --extend-select RUF100 test.py`, we should expect to get this error:
```
test.py:1:19: RUF100 Unused `noqa` directive (unused: `F401`)
```
The issue is that the per-file-ignores diagnostics are filtered out after the noqa checks, rather than before.
Fixes a regression introduced in eda2be6350 (but not yet released to users). (`-v` is a real flag, but it's an alias for `--verbose`, not `--version`.)
Closes#2299.
We probably want to introduce multiple explain subcommands and
overloading `explain` to explain it all seems like a bad idea.
We may want to introduce a subcommand to explain config options and
config options may end up having the same name as their rules, e.g. the
current `banned-api` is both a rule name (although not yet exposed to
the user) and a config option.
The idea is:
* `ruff rule` lists all rules supported by ruff
* `ruff rule <code>` explains a specific rule
* `ruff linter` lists all linters supported by ruff
* `ruff linter <name>` lists all rules/options supported by a specific linter
(After this commit only the 2nd case is implemented.)
This commit greatly simplifies the implementation of the CLI,
as well as the user expierence (since --help no longer lists all
options even though many of them are in fact incompatible).
To preserve backwards-compatability as much as possible aliases have
been added for the new subcommands, so for example the following two
commands are equivalent:
ruff explain E402 --format json
ruff --explain E402 --format json
However for this to work the legacy-format double-dash command has to
come first, i.e. the following no longer works:
ruff --format json --explain E402
Since ruff previously had an implicitly default subcommand,
this is preserved for backwards compatibility, i.e. the following two
commands are equivalent:
ruff .
ruff check .
Previously ruff didn't complain about several argument combinations that
should have never been allowed, e.g:
ruff --explain RUF001 --line-length 33
previously worked but now rightfully fails since the explain command
doesn't support a `--line-length` option.
I presume the reasoning for not including clippy in `pre-commit` was that it passes all files. This can be turned off with `pass_filenames`, in which case it only runs once.
`cargo +nightly dev generate-all` is also added (when excluding `target` is does not give false positives).
(The overhead of these commands is not much when the build is there. People can always choose to run only certain hooks with `pre-commit run [hook] --all-files`)
