This is just a hack to allow rustup to work on macOS and windows again to distribute std documentation (hopefully once rust-lang/rfcs#3097 or an equivalent is merged).

Fixes #80504. Prevents #83154 and rust-lang/rustup#2694 in future releases.

@GuillaumeGomez could you double check this generates keyword.SelfTy.html? Ideally I'd like the lint I mention in rust-lang/rfcs#3097 (comment), but you don't need to add it if it's a burden, just manually checking that the list of duplicates from

build_case_insensitive_map(&krate, &options)
is empty is fine by me.

You need to update

fn is_doc_keyword(s: Symbol) -> bool {
s <= kw::Union
}
.

Err actually I think I would just #[allow] the lint for now on that specific item.

Sure, adding a test for it then.

I intended to do that. :3 (and yet another lint I added which prevents me from doing bad things. Sorry past me...)

Actually, testing the existence of a file isn't that easy. But I can confirm that the rust/build/x86_64-unknown-linux-gnu/doc/std/keyword.SelfTy.html file was generated for me.

What about something like this?

#![crate_name = "foo"]

#[doc(keyword = "banana")]
mod banana_keyword {}

// @has foo/keyword.banana.html ''

@camelid We already check that the doc(keyword) is working. I think that @jyn514 was talking specifically about SelfTy.

Hmm, maybe we should also add a note to the SelfTy docs that say that the actual keyword is Self and it's named SelfTy because of a bug? Otherwise I imagine it could be quite confusing for readers of the docs.
