The idea with this pull request is to move code generated out of lib.rs and into includes.

The benefit is that moves a lot of clutter out of lib.rs. It's also easier to do the generation as a whole file can be replaced instead of a region and these files aren't formatted by rustfmt.

Some things still be done are:

  • Fix cargo dev new_lint
  • Agree on what the include filenames should be
  • Agree on the format of the generated code (e.g. comment at the top, end in new line etc.)
  • Refactor the update_lints code

This is a big change and it might be a bad idea. Feel free to close.

I'll finish this off if it gets a thumbs up.

I like this change. This will also make syncing with rustc easier, since conflicts in those auto-generated files can just be ignored and lib.rs won't have as much churn.

Agree on the format of the generated code (e.g. comment at the top, end in new line etc.)

I would add a newline at the end of the file and keep the format consistent. Some files have indentation, some don't. I would format those files as close as possible to what rustfmt would do. (see comments below)

Before you continue working on this, I'd wait for more feedback from @rust-lang/clippy though

I like the idea, +1 from me.

If we continue this, could you please make sure to also include the automatically generated files in our pre-commit hook? 🙃

Sounds like a good idea, I like it.

Do we want to move this PR forward once it was rebased? There seems to be no objections so far 🙃

Sorry for the late reviewing. I've been a bit busy. Please give me a few more days.

Generated files LGTM. I didn't review the clippy_dev changes.

There were no objections to this in the last meeting, so once @giraffate is done with the review, this can be merged.

Also change the generation functions to return `String` instead of
`Vec<String>`. This makes sense now as the updates aren't line oriented

Sorry for the late review, again.

Over all looks good, Thanks! I made one minor comment.

Ooh, this has made rustfmt stop working for the entire codebase since the modules are include!d and rustfmt doesn't read that.

Trying to fix that in #7773

Auto merge of #7773 - Manishearth:update-lints-mods, r=flip1995

Move module declarations back into lib.rs

With #7673 we moved a lot of things from lib.rs to lib.foo.rs. Unfortunately, rustfmt doesn't seem to work when module declarations are included via `include!` (and trying the `mod foo; use foo::*;` trick doesn't seem to work much either in our specific case).

With this PR we continue generating everything in subfiles except for module declarations, which are now generated within lib.rs.
