bors 1765c5da90 Auto merge of #5363 - yaahc:clippy-fix, r=phansch,flip1995 ... add --fix support to `cargo-clippy` Prior to this we had started work on integrating clippy as a subcommand directly into cargo in the form of `cargo clippy-preview` and `cargo fix --clippy`. In the course of that work it was decided that the best approach would be to strictly add the features clippy needed to cargo in order to insert `clippy-driver` only for workspace crates. This was accomplished by adding a `RUSTC_WORKSPACE_WRAPPER` env variable to cargo that will override the normal `RUSTC_WRAPPER` when both are present and the current crate is a workspace crate. This change adds support to clippy to use this by setting the `RUSTC_WORKSPACE_WRAPPER` env variable instead `RUSTC_WRAPPER` and by detecting `--fix` as an arg and swapping out the `check` cargo command for `fix` when it is present. WIP, here are the current issues that I still need to resolve - [x] Detect if we're running on nightly rust - [x] Set `RUSTC_WORKSPACE_WRAPPER` on nightly, and `RUSTC_WRAPPER` on stable - [x] Error out on stable when `--fix` is specified, because stable currently hasn't landed the PR for `RUSTC_WORKSPACE_WRAPPER` so if we set this it just runs check and silently fails - [ ] Update the help text - [ ] The current plan is to shell out to `cargo check --help` and then postprocess the output to mention clippy instead of check where appropriate and to add the extra info about `--fix` and the `-- -A lint` options. - [x] tests? changelog: add `--fix` arg to `cargo-clippy`		2020-04-15 22:38:42 +00:00
