Add new lint `negative_feature_names` and `redundant_feature_names`
Add new lint [`negative_feature_names`] to detect feature names with prefixes `no-` or `not-` and new lint [`redundant_feature_names`] to detect feature names with prefixes `use-`, `with-` or suffix `-support`
changelog: Add new lint [`negative_feature_names`] and [`redundant_feature_names`]
* Captures by sub closures are now considered
* Copy types are correctly borrowed by reference when their value is used
* Fields are no longer automatically borrowed by value
* Bindings in `match` and `let` patterns are now checked to determine how a local is captured
Add `unwrap_or_else_default` lint

*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: Add a new [`unwrap_or_else_default`] style lint. This will catch `unwrap_or_else(Default::default)` on Result and Option and suggest `unwrap_or_default()` instead.
`never_loop`: suggest using an `if let` instead of a `for` loop
changelog: suggest using an `if let` statement instead of a `for` loop that [`never_loop`]s
Fixes#7537, r? `@camsteffen.`
Don't emit `too_many_lines` for closures
changelog: don't emit the [`too_many_lines`] lint inside closures to avoir duplicated diagnostics.
Fixes#7517.
Make `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` warn by default
This PR makes the `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` lint warn by default.
To avoid showing a large number of un-actionable warnings to users, we only enable the lint for macros defined in the same crate. This ensures that users will be able to fix the warning by simply removing a semicolon.
In the future, I'd like to enable this lint unconditionally, and eventually make it into a hard error in a future edition. This PR is a step towards that goal.
This updates all the deploy scripts and the deploy workflow.
The deploy workflow now runs the metadata collector to collect the lint
documentation. It also changes the files that are checked out in the
deploy workflow from master and adds an explanation why we have to do
this.
Explain flags missing in cargo check in --help
This commit closes#7389. As stated in the issue, `cargo clippy --help`
provides explanation for some flags and states that the rest are same
as in `cargo check --help`, even though some clippy specific flags
exist.
This commit extends the `cargo clippy --help` with two additional flags,
- `cargo clippy --fix`
- `cargo clippy --no-deps`
If there are more flags which are not present in `cargo check --help`
please bring these to my attention, I will include these aswell.
For now, I noticed only the two flags mentioned above.
changelog: `cargo clippy --help` now explains additional flags missing in `cargo check --help`.
Fix docs of disallowed_type
Add ability to name primitive types without import path
Move primitive resolution to clippy_utils path_to_res fn
Refactor Res matching, fix naming and docs from review
Use tcx.def_path_str when emitting the lint
As proposed in the pull request thread, there is some inconsistency in
handling the `--no-deps` flag which requires `--` before it, and
`--fix` flag which does not.
In this commit the `--no-deps` flag does not need the `--` anymore.
However, it can still be used that way: `cargo clipyy -- --no-deps`.
Use diagnostic items where possible
Clippy still uses a bunch of paths in places that could easily use already defined diagnostic items. This PR updates all references to such paths and also removes a bunch of them that are no longer needed after this cleanup.
Some paths are also used to construct new paths and can therefore not be removed that easily. I've added a doc comment to those instances that recommends the use of the diagnostic item where possible.
And that's it, cleaning crew signing off 🧹🗑️
