In order to avoid confusing new developers. When a debug build panics
chances are that the panic is caused by local changes and should in
fact not be reported on GitHub.
Ruff allows rules to be enabled with `select` and disabled with
`ignore`, where the more specific rule selector takes precedence,
for example:
`--select ALL --ignore E501` selects all rules except E501
`--ignore ALL --select E501` selects only E501
(If both selectors have the same specificity ignore selectors
take precedence.)
Ruff always had two quirks:
* If `pyproject.toml` specified `ignore = ["E501"]` then you could
previously not override that with `--select E501` on the command-line
(since the resolution didn't take into account that the select was
specified after the ignore).
* If `pyproject.toml` specified `select = ["E501"]` then you could
previously not override that with `--ignore E` on the command-line
(since the resolution didn't take into account that the ignore was
specified after the select).
Since d067efe265 (#1245)
`extend-select` and `extend-ignore` always override
`select` and `ignore` and are applied iteratively in pairs,
which introduced another quirk:
* If some `pyproject.toml` file specified `extend-select`
or `extend-ignore`, `select` and `ignore` became pretty much
unreliable after that with no way of resetting that.
This commit fixes all of these quirks by making later configuration
sources take precedence over earlier configuration sources.
While this is a breaking change, we expect most ruff configuration
files to not rely on the previous unintutive behavior.
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
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.
`ruff --help` previously listed 37 options in no particular order
(with niche options like --isolated being listed before before essential
options such as --select). This commit remedies that and additionally
groups the options by making use of the Clap help_heading feature.
Note that while the source code has previously also referred to
--add-noqa, --show-settings, and --show-files as "subcommands"
this commit intentionally does not list them under the new
Subcommands section since contrary to --explain and --clean
combining them with most of the other options makes sense.
We already enforced pedantic clippy lints via the
following command in .github/workflows/ci.yaml:
cargo clippy --workspace --all-targets --all-features -- -D warnings -W clippy::pedantic
Additionally adding #![warn(clippy::pedantic)] to all main.rs and lib.rs
has the benefit that violations of pedantic clippy lints are also
reported when just running `cargo clippy` without any arguments and
are thereby also picked up by LSP[1] servers such as rust-analyzer[2].
However for rust-analyzer to run clippy you'll have to configure:
"rust-analyzer.check.command": "clippy",
in your editor.[3]

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.
To enable ruff_dev to automatically generate the rule Markdown tables in
the README the ruff library contained the following function:
Linter::codes() -> Vec<RuleSelector>
which was slightly changed to `fn prefixes(&self) -> Prefixes` in
9dc66b5a65 to enable ruff_dev to split
up the Markdown tables for linters that have multiple prefixes
(pycodestyle has E & W, Pylint has PLC, PLE, PLR & PLW).
The definition of this method was however largely redundant with the
#[prefix] macro attributes in the Linter enum, which are used to
derive the Linter::parse_code function, used by the --explain command.
This commit removes the redundant Linter::prefixes by introducing a
same-named method with a different signature to the RuleNamespace trait:
fn prefixes(&self) -> &'static [&'static str];
As well as implementing IntoIterator<Rule> for &Linter. We extend the
extisting RuleNamespace proc macro to automatically derive both
implementations from the Linter enum definition.
To support the previously mentioned Markdown table splitting we
introduce a very simple hand-written method to the Linter impl:
fn categories(&self) -> Option<&'static [LinterCategory]>;
ParseCode was a fitting name since the trait only contained a single
parse_code method ... since we now however want to introduce an
additional `prefixes` method RuleNamespace is more fitting.
543865c96b introduced
RuleCode::origin() -> RuleOrigin generation via a macro, while that
signature now has been renamed to Rule::origin() -> Linter we actually
want to get rid of it since rules and linters shouldn't be this tightly
coupled (since one rule can exist in multiple linters).
Another disadvantage of the previous approach was that the prefixes
had to be defined in ruff_macros/src/prefixes.rs, which was easy to
miss when defining new linters in src/*, case in point
INP001 => violations::ImplicitNamespacePackage has in the meantime been
added without ruff_macros/src/prefixes.rs being updated accordingly
which resulted in `ruff --explain INP001` mistakenly reporting that the
rule belongs to isort (since INP001 starts with the isort prefix "I").
The derive proc macro introduced in this commit requires every variant
to have at least one #[prefix = "..."], eliminating such mistakes.
More accurate since the enum also encompasses:
* ALL (which isn't a prefix at all)
* fully-qualified rule codes (which aren't prefixes unless you say
they're a prefix to the empty string but that's not intuitive)
