Fix lints handling in rustdoc #60908

GuillaumeGomez · 2019-05-17T08:42:53Z

Part of #60664: now lints are handled just like any other lints you would setup in rustc. Still remains to handle missing code examples and missing_docs as part of the same group.

Oh awesome!

Updated! Let's just wait for CI first, a test is incomplete, I can't make it run locally so I'm waiting for CI to give me the stderr. :-°

@pietroalbini Any idea why we don't have highfive starting rustdoc UI test in here? :'(

I don't see any exception, I'll try to investigate a bit later.

Thanks!

I fixed the tests and also fixed the tests not running locally for some reasons...

Please mention in the commit description or the PR description what part of the issue is actually being fixed

I updated the first comment of the PR. Do you think this is enough or should I add something else?

@oli-obk

Fix lints handling in rustdoc Part of rust-lang#60664: now lints are handled just like any other lints you would setup in rustc. Still remains to handle `missing code examples` and `missing_docs` as part of the same group. r? @oli-obk
