For consistency with `rustc_lexer::TokenKind::Bang`, and because other
`ast::TokenKind` variants generally have syntactic names instead of
semantic names (e.g. `Star` and `DotDot` instead of `Mul` and `Range`).
|
|
`BinOpToken` is badly named, because it only covers the assignable
binary ops and excludes comparisons and `&&`/`||`. Its use in
`ast::TokenKind` does allow a small amount of code sharing, but it's a
clumsy factoring.
This commit removes `ast::TokenKind::BinOp{,Eq}`, replacing each one
with 10 individual variants. This makes `ast::TokenKind` more similar to
`rustc_lexer::TokenKind`, which has individual variants for all
operators.
Although the number of lines of code increases, the number of chars
decreases due to the frequent use of shorter names like `token::Plus`
instead of `token::BinOp(BinOpToken::Plus)`.

`librustdoc`: return `impl fmt::Display` in more places instead of writing to strings
Continuation of #136784 , another attempt at landing the larger parts of #136748 .
I'd like to, gradually, make all of the building blocks for rendering docs in `librustdoc` return `impl fmt::Display` instead of returning `Strings`, or receiving a `&mut String` (or `&mut impl fmt::Write`). Another smaller end goal is to be able to get rid of [`write_str`](https://github.com/rust-lang/rust/blob/8dac72bb1d12b2649acd0c190e41524f83da5683/src/librustdoc/html/format.rs#L40-L42).
This PR is a large step in that direction.
Most of the changes are quite mechanical, and split up into separate commits for easier reviewing (hopefully). I took `print_item` and then started by converting all the functions it called (and their dependencies), and the last commit does the conversion for `print_item` itself. Ignoring whitespace should make reviewing a bit easier.
And most importantly, perf run shows pretty good results locally, hopefully CI will also show green 😁

Complete the list of resources used in rustdoc output
The Nanum Barun Gothic Font was missing in the list and should clearly be mentionned.
Arguably referencing the Rust logos is not really necessary as the file mentions "third party resources" but it doesn't hurt and should make things clearer for anybody who wants to publish their Rust doc.

New attribute parsing infrastructure
Another step in the plan outlined in https://github.com/rust-lang/rust/issues/131229
introduces infrastructure for structured parsers for attributes, as well as converting a couple of complex attributes to have such structured parsers.
This PR may prove too large to review. I left some of my own comments to guide it a little. Some general notes:
- The first commit is basically standalone. It just preps some mostly unrelated sources for the rest of the PR to work. It might not have enormous merit on its own, but not negative merit either. Could be merged alone, but also doesn't make the review a whole lot easier. (but it's only +274 -209)
- The second commit is the one that introduces new infrastructure. It's the important one to review.
- The 3rd commit uses the new infrastructure showing how some of the more complex attributes can be parsed using it. Theoretically can be split up, though the parsers in this commit are the ones that really test the new infrastructure and show that it all works.
- The 4th commit fixes up rustdoc and clippy. In the previous 2 they didn't compile yet while the compiler does. Separated them out to separate concerns and make the rest more palatable.
- The 5th commit blesses some test outputs. Sometimes that's just because a diagnostic happens slightly earlier than before, which I'd say is acceptable. Sometimes a diagnostic is now only emitted once where it would've been twice before (yay! fixed some bugs). One test I actually moved from crashes to fixed, because it simply doesn't crash anymore. That's why this PR Closes #132391. I think most choices I made here are generally reasonable, but let me know if you disagree anywhere.
- The 6th commit adds a derive to pretty print attributes
- The 7th removes smir apis for attributes, for the time being. The api will at some point be replaced by one based on `rustc_ast_data_structures::AttributeKind`
In general, a lot of the additions here are comments. I've found it very important to document new things in the 2nd commit well so other people can start using it.
Closes #132391
Closes #136717

[rustdoc] Add new setting to wrap source code lines when too long
Fixes https://github.com/rust-lang/rust/issues/127334.
Wrapped lines look like this:

It works in both source code pages and doc pages.
You can test it [here](https://rustdoc.crud.net/imperio/code-wrapping/bar/index.html).

librustdoc: Use `pulldown-cmark-escape` for HTML escaping
Implementation of `@notriddle` 's [suggestion](https://github.com/rust-lang/rust/pull/137274#issuecomment-2669001585).
Somewhat related to #137274 , but the two PRs should be complementary.
Local perf results look like a nice improvement! (so would love a perf run on the CI)

librustdoc: more usages of `Joined::joined`
Some missed opportunities from #136244
r? ```@GuillaumeGomez``` since you reviewed the last one (feel free to re-assign, of course 😊)

|

Continuing the work started in #136466.
Every method gains a `hir_` prefix, though for the ones that already
have a `par_` or `try_par_` prefix I added the `hir_` after that.

It's a trivial wrapper around the `hir_crate` query with a small number
of uses.
|
|
First of all, note that `Map` has three different relevant meanings.
- The `intravisit::Map` trait.
- The `map::Map` struct.
- The `NestedFilter::Map` associated type.
The `intravisit::Map` trait is impl'd twice.
- For `!`, where the methods are all unreachable.
- For `map::Map`, which gets HIR stuff from the `TyCtxt`.
As part of getting rid of `map::Map`, this commit changes `impl
intravisit::Map for map::Map` to `impl intravisit::Map for TyCtxt`. It's
fairly straightforward except various things are renamed, because the
existing names would no longer have made sense.
- `trait intravisit::Map` becomes `trait intravisit::HirTyCtxt`, so named
because it gets some HIR stuff from a `TyCtxt`.
- `NestedFilter::Map` assoc type becomes `NestedFilter::MaybeTyCtxt`,
because it's always `!` or `TyCtxt`.
- `Visitor::nested_visit_map` becomes `Visitor::maybe_tcx`.
I deliberately made the new trait and associated type names different to
avoid the old `type Map: Map` situation, which I found confusing. We now
have `type MaybeTyCtxt: HirTyCtxt`.
|
|
The end goal is to eliminate `Map` altogether.
I added a `hir_` prefix to all of them, that seemed simplest. The
exceptions are `module_items` which became `hir_module_free_items` because
there was already a `hir_module_items`, and `items` which became
`hir_free_items` for consistency with `hir_module_free_items`.

rustdoc: improve refdef handling in the unresolved link lint
This commit takes advantage of a feature in pulldown-cmark that makes the list of link definitions available to the consuming application. It produces unresolved link warnings for refdefs that aren't used, and can now produce exact spans for the dest even when it has escapes.
Closes #133150 since this lint would have caught the mistake in that issue, and, along with https://github.com/rust-lang/rust-clippy/pull/13707, most mistakes in this class should produce a warning from one of them.

rustdoc: Properly restore search input placeholder
Fix the search input placeholder literally getting set to the string *undefined* on blur/defocus.
This was caused by us trying to access an undefined property in the event listener.
To prevent this from regressing again, stop typescript from ignoring the relevant site.
Steps to reproduce the bug fixed in this PR:
1. Focus the search input field by clicking on it and clear the input if necessary
2. Blur/defocus it by clicking somewhere outside of it
---
First bug that would've been caught by TSC if we had had it earlier! Type (quasi-)safety, ahoy! :)
