For example:
$ ruff check --select=EM<Tab>
EM -- flake8-errmsg
EM10 EM1 --
EM101 -- raw-string-in-exception
EM102 -- f-string-in-exception
EM103 -- dot-format-in-exception

in the Autocompletion section in the README.)
Fixes#2808.
(The --help help change in the README is due to a clap bug,
for which I already submitted a fix:
https://github.com/clap-rs/clap/pull/4710.)
Rule::noqa_code previously return a single &'static str,
which was possible because we had one enum listing all
rule code prefixes. This commit series will however split up
the RuleCodePrefix enum into several enums ... so we'll end up
with two &'static str ... this commit wraps the return type
of Rule::noqa_code into a newtype so that we can easily change
it to return two &'static str in the 6th commit of this series.
Post this commit series several codes can be mapped to a single rule,
this commit therefore renames Rule::code to Rule::noqa_code,
which is the code that --add-noqa will add to ignore a rule.
This is causing wheel creation to fail on some of our more exotic build targets: 4159524132.
Let's figure out how to gate appropriately, but for now, reverting to get the release out.
The synopsis is as follows.
List all top-level config keys:
$ ruff config
allowed-confusables
builtins
cache-dir
... etc.
List all config keys in a specific section:
$ ruff config mccabe
max-complexity
Describe a specific config option:
$ ruff config mccabe.max-complexity
The maximum McCabe complexity to allow before triggering `C901` errors.
Default value: 10
Type: int
Example usage:
```toml
# Flag errors (`C901`) whenever the complexity level exceeds 5.
max-complexity = 5
```
The new `ruff rule` output format introduced in
551b810aeb doesn't print Markdown but
rather some rich text with escape sequences for colors and links,
it's actually the "text" format that prints Markdown, so naming the new
format "markdown" is very confusing. This commit therefore renames it to
"pretty".
This isn't a breaking change since there hasn't been a release yet.
```console
❯ cargo run rule B017
Finished dev [unoptimized + debuginfo] target(s) in 0.13s
Running `target/debug/ruff rule B017`
no-assert-raises-exception
Code: B017 (flake8-bugbear)
### What it does
Checks for `self.assertRaises(Exception)`.
## Why is this bad?
`assertRaises(Exception)` can lead to your test passing even if the
code being tested is never executed due to a typo.
Either assert for a more specific exception (builtin or custom), use
`assertRaisesRegex` or the context manager form of `assertRaises`.
