For example, the search queries `simd -> simd` and `simd -> simd` don't link to the same function, but most of the functions have the same names. This change should probably be FCP-ed, especially since it adds a new anchor link format for `main.js` to handle, so that URLs like `struct.Vec.html#impl-AsMut<[T]>-for-Vec/method.as_mut` redirect to `struct.Vec.html#method.as_mut-2`. It's a strange design, but there are a few reasons for it: * I'd like to avoid making the HTML bigger. Obviously, fixing this bug is going to add at least a little more data to the search index, but adding more HTML penalises viewers for the benefit of searchers. * Breaking `struct.Vec.html#method.len` would also be a disappointment. On the other hand: * The path-style anchors might be less prone to link rot than the numbered anchors. It's definitely less likely to have URLs that appear to "work", but silently point at the wrong thing. * This commit arranges the path-style anchor to redirect to the numbered anchor. Nothing stops rustdoc from doing the opposite, making path-style anchors the default and redirecting the "legacy" numbered ones. --- src/librustdoc/formats/cache.rs | 13 ++++ src/librustdoc/html/render/mod.rs | 41 +++++++---- src/librustdoc/html/render/search_index.rs | 33 ++++++++- src/librustdoc/html/render/sidebar.rs | 3 +- src/librustdoc/html/static/js/main.js | 24 +++++++ src/librustdoc/html/static/js/search.js | 19 ++++- .../search-result-impl-disambiguation.goml | 41 +++++++++++ tests/rustdoc-gui/src/test_docs/lib.rs | 18 +++++ tests/rustdoc-js-std/simd-type-signatures.js | 70 +++++++++++++++++++ .../rustdoc-js/search-method-disambiguate.js | 28 ++++++++ .../rustdoc-js/search-method-disambiguate.rs | 22 ++++++ tests/rustdoc/issue-32077-type-alias-impls.rs | 2 +- 12 files changed, 293 insertions(+), 21 deletions(-) create mode 100644 tests/rustdoc-gui/search-result-impl-disambiguation.goml create mode 100644 tests/rustdoc-js-std/simd-type-signatures.js create mode 100644 tests/rustdoc-js/search-method-disambiguate.js create mode 100644 tests/rustdoc-js/search-method-disambiguate.rs diff --git a/src/librustdoc/formats/cache.rs b/src/librustdoc/formats/cache.rs index 898aaa3e1962..b916baecc140 100644 --- a/src/librustdoc/formats/cache.rs +++ b/src/librustdoc/formats/cache.rs @@ -350,6 +350,11 @@ impl<'a, 'tcx> DocFolder for CacheBuilder<'a, 'tcx> { desc, parent, parent_idx: None, + impl_id: if let Some(ParentStackItem::Impl { item_id, .. }) = self.cache.parent_stack.last() { + item_id.as_def_id() + } else { + None + }, search_type: get_function_type_for_search( &item, self.tcx, @@ -369,6 +374,13 @@ impl<'a, 'tcx> DocFolder for CacheBuilder<'a, 'tcx> { parent, item: item.clone(), impl_generics, + impl_id: if let Some(ParentStackItem::Impl { item_id, .. }) = + self.cache.parent_stack.last() + { + item_id.as_def_id() + } else { + None + }, });

This results in the format changing a little bit; full paths are used in spots where they aren't strictly necessary, and the path sometimes uses generics where the old system used the trait's own name, but it shouldn't matter since the orphan rules will prevent it anyway. --- tests/rustdoc-js-std/simd-type-signatures.js | 40 +++++++++---------- tests/rustdoc/blanket-reexport-item.rs | 2 +- tests/rustdoc/const-generics/const-impl.rs | 2 +- tests/rustdoc/generic-impl.rs | 4 +- tests/rustdoc/issue-78701.rs | 2 +- .../primitive/primitive-generic-impl.rs | 2 +- .../rustdoc/sidebar-links-to-foreign-impl.rs | 4 +- tests/rustdoc/src-links-auto-impls.rs | 4 +- tests/rustdoc/where-clause-order.rs | 13 +++++- 9 files changed, 42 insertions(+), 31 deletions(-) diff --git a/tests/rustdoc-js-std/simd-type-signatures.js b/tests/rustdoc-js-std/simd-type-signatures.js index bd1682709573..5c7cf372bce1 100644 --- a/tests/rustdoc-js-std/simd-type-signatures.js +++ b/tests/rustdoc-js-std/simd-type-signatures.js @@ -11,29 +11,29 @@ const EXPECTED = [ 'query': 'simd, simd -> simd', 'others': [ { -

This also lets `State::Stabilized` (which was a terrible name) be removed. --- compiler/rustc_expand/src/config.rs | 12 +++--------- compiler/rustc_feature/src/lib.rs | 5 +---- compiler/rustc_feature/src/removed.rs | 27 +++++---------------------- 3 files changed, 9 insertions(+), 35 deletions(-) diff --git a/compiler/rustc_expand/src/config.rs b/compiler/rustc_expand/src/config.rs index e3d0af80c6a2..d3f792601b79 100644 --- a/compiler/rustc_expand/src/config.rs +++ b/compiler/rustc_expand/src/config.rs @@ -15,9 +15,7 @@ use rustc_attr as attr; use rustc_data_structures::flat_map_in_place::FlatMapInPlace; use rustc_data_structures::fx::FxHashMap; use rustc_feature::{Feature, Features, State as FeatureState}; -use rustc_feature::{ - ACCEPTED_FEATURES, ACTIVE_FEATURES, REMOVED_FEATURES, STABLE_REMOVED_FEATURES, -}; +use rustc_feature::{ACCEPTED_FEATURES, ACTIVE_FEATURES, REMOVED_FEATURES}; use rustc_parse::validate_attr; use rustc_session::parse::feature_err; use rustc_session::Session; @@ -154,12 +152,8 @@ pub fn features(sess: &Session, krate_attrs: &[Attribute]) -> Features { } // If the declared feature is removed, issue an error. - let removed = REMOVED_FEATURES.iter().find(|f| name == f.name); - let stable_removed = STABLE_REMOVED_FEATURES.iter().find(|f| name == f.name); - if let Some(Feature { state, .. }) = removed.or(stable_removed) { - if let FeatureState::Removed { reason } | FeatureState::Stabilized { reason } = - state - { + if let Some(Feature { state, .. }) = REMOVED_FEATURES.iter().find(|f| name == f.name) { + if let FeatureState::Removed { reason } = state { sess.emit_err(FeatureRemoved { span: mi.span(), reason: reason.map(|reason| FeatureRemovedReason { reason }), diff --git a/compiler/rustc_feature/src/lib.rs b/compiler/rustc_feature/src/lib.rs index d4dc5920becc..4721bff0ec71 100644 --- a/compiler/rustc_feature/src/lib.rs +++ b/compiler/rustc_feature/src/lib.rs @@ -32,7 +32,6 @@ pub enum State { Accepted, Active { set: fn(&mut Features) }, Removed { reason: Option<&'static str> }, - Stabilized { reason: Option<&'static str> }, } impl fmt::Debug for State { @@ -41,7 +40,6 @@ impl fmt::Debug for State { State::Accepted { .. } => write!(f, "accepted"), State::Active { .. } => write!(f, "active"), State::Removed { .. } => write!(f, "removed"), - State::Stabilized { .. } => write!(f, "stabilized"), } } } @@ -113,7 +111,6 @@ fn find_lang_feature_issue(feature: Symbol) -> Option { .chain(ACTIVE_FEATURES) .chain(ACCEPTED_FEATURES) .chain(REMOVED_FEATURES) - .chain(STABLE_REMOVED_FEATURES) .find(|t| t.name == feature); match found { @@ -151,4 +148,4 @@ pub use builtin_attrs::{ is_valid_for_get_attr, AttributeGate, AttributeTemplate, AttributeType, BuiltinAttribute, GatedCfg, BUILTIN_ATTRIBUTES, BUILTIN_ATTRIBUTE_MAP, }; -pub use removed::{REMOVED_FEATURES, STABLE_REMOVED_FEATURES}; +pub use removed::REMOVED_FEATURES; diff --git a/compiler/rustc_feature/src/removed.rs b/compiler/rustc_feature/src/removed.rs index da18cb2a239e..de15deef1789 100644 --- a/compiler/rustc_feature/src/removed.rs +++ b/compiler/rustc_feature/src/removed.rs @@ -20,23 +20,6 @@ macro_rules! declare_features { ),+ ]; }; - - ($( - $(#[doc = $doc:tt])* (stable_removed, $feature:ident, $ver:expr, $issue:expr, None), - )+) => { - /// Represents stable features which have since been removed (it was once Accepted) - pub const STABLE_REMOVED_FEATURES: &[Feature] = &[ - $( - Feature { - state: State::Stabilized { reason: None }, - name: sym::$feature, - since: $ver, - issue: to_nonzero($issue), - edition: None, - } - ),+ - ]; - }; } #[rustfmt::skip] @@ -141,6 +124,11 @@ declare_features!

The new way of doing things: - Avoids some code duplication. - Distinguishes the `crate_edition` (which comes from `--edition`) and the `features_edition` (which combines `--edition` along with any `rustc_20XX_preview` features), which is useful. - Has a simpler initial loop, one that just looks for `rustc_20XX_preview` features in order to compute `features_edition`. - Creates a fallible alternative to `Features::enabled`, which is useful. It's not easy to see how exactly the old and new code are equivalent, but it's reassuring to know that the test coverage is quite good for this stuff. --- compiler/rustc_expand/src/config.rs | 103 +++++++++++++--------------- 1 file changed, 46 insertions(+), 57 deletions(-) diff --git a/compiler/rustc_expand/src/config.rs b/compiler/rustc_expand/src/config.rs index d3f792601b79..b3ee755f565d 100644 --- a/compiler/rustc_expand/src/config.rs +++ b/compiler/rustc_expand/src/config.rs @@ -13,7 +13,7 @@ use rustc_ast::NodeId; use rustc_ast::{self as ast, AttrStyle, Attribute, HasAttrs, HasTokens, MetaItem}; use rustc_attr as attr; use rustc_data_structures::flat_map_in_place::FlatMapInPlace; -use rustc_data_structures::fx::FxHashMap; +use rustc_data_structures::fx::FxHashSet; use rustc_feature::{Feature, Features, State as FeatureState}; use rustc_feature::{ACCEPTED_FEATURES, ACTIVE_FEATURES, REMOVED_FEATURES}; use rustc_parse::validate_attr; @@ -55,55 +55,37 @@ pub fn features(sess: &Session, krate_attrs: &[Attribute]) -> Features { } let mut features = Features::default(); - let mut edition_enabled_features = FxHashMap::default(); + + // The edition from `--edition`. let crate_edition = sess.edition(); - // Enable edition umbrella feature-gates based on the crate edition. - // - enable `rust_2015_preview` always - // - enable `rust_2018_preview` if the crate edition is 2018 or higher - // - enable `rust_2021_preview` if the crate edition is 2021 or higher - // - etc. - for &edition in ALL_EDITIONS { - if edition <= crate_edition { - edition_enabled_features.insert(edition.feature_name(), edition); - } - } - - // Enable edition-dependent features based on the crate edition. - // - E.g. `test_2018_feature` if the crate edition is 2018 or higher - for feature in active_features_up_to(crate_edition) { - feature.set(&mut features); - edition_enabled_features.insert(feature.name, crate_edition); - } - - // Enable edition umbrella feature-gates that are declared in the code.

The word "active" is currently used in two different and confusing ways: - `ACTIVE_FEATURES` actually means "available unstable features" - `Features::active_features` actually means "features declared in the crate's code", which can include feature within `ACTIVE_FEATURES` but also others. (This is also distinct from "enabled" features which includes declared features but also some edition-specific features automatically enabled depending on the edition in use.) This commit changes the `Features::active_features` to `Features::declared_features` which actually matches its meaning. Likewise, `Features::active` becomes `Features::declared`. --- compiler/rustc_expand/src/config.rs | 6 +++--- compiler/rustc_feature/src/active.rs | 15 +++++++++------ compiler/rustc_middle/src/middle/stability.rs | 6 +++--- .../clippy_lints/src/manual_float_methods.rs | 2 +- 4 files changed, 16 insertions(+), 13 deletions(-) diff --git a/compiler/rustc_expand/src/config.rs b/compiler/rustc_expand/src/config.rs index b3ee755f565d..ed619e02f57f 100644 --- a/compiler/rustc_expand/src/config.rs +++ b/compiler/rustc_expand/src/config.rs @@ -155,7 +155,7 @@ pub fn features(sess: &Session, krate_attrs: &[Attribute]) -> Features { if let Some(Feature { since, .. }) = ACCEPTED_FEATURES.iter().find(|f| name == f.name) { let since = Some(Symbol::intern(since)); features.declared_lang_features.push((name, mi.span(), since)); - features.active_features.insert(name); + features.declared_features.insert(name); continue; } @@ -173,14 +173,14 @@ pub fn features(sess: &Session, krate_attrs: &[Attribute]) -> Features { if let Some(f) = ACTIVE_FEATURES.iter().find(|f| name == f.name) { f.set(&mut features); features.declared_lang_features.push((name, mi.span(), None)); - features.active_features.insert(name); + features.declared_features.insert(name); continue; } // Otherwise, the feature is unknown.

From 28ee5da4b7595465633e5852e0d5d1632fec02ae Mon Sep 17 00:00:00 2001 From: Michael Howell Date: Mon, 18 Sep 2023 11:59:49 -0700 Subject: [PATCH 269/350] rustdoc: show crate name beside small logo This commit changes the layout to something a bit less "look at my logo!!!111" gigantic, and makes it clearer where clicking the logo will actually take you. It also means the crate name is persistently at the top of the sidebar, even when in a sub-item page, and clicking that name takes you back to the root. | | Short crate name | Long crate name | |---------|------------------|-----------------| | Root | ![short-root] | ![long-root] | Subpage | ![short-subpage] | ![long-subpage] [short-root]: https://github.com/rust-lang/rust/assets/1593513/fe2ce102-d4b8-44e6-9f7b-68636a907f56 [short-subpage]: https://github.com/rust-lang/rust/assets/1593513/29501663-56c0-4151-b7de-d2637e167125 [long-root]: https://github.com/rust-lang/rust/assets/1593513/f6a385c0-b4c5-4a9c-954b-21b38de4192f [long-subpage]: https://github.com/rust-lang/rust/assets/1593513/97ec47b4-61bf-4ebe-b461-0d2187b8c6ca https://notriddle.com/rustdoc-html-demo-4/logo-lockup/image/index.html https://notriddle.com/rustdoc-html-demo-4/logo-lockup/crossbeam_channel/index.html https://notriddle.com/rustdoc-html-demo-4/logo-lockup/adler/struct.Adler32.html https://notriddle.com/rustdoc-html-demo-4/logo-lockup/crossbeam_channel/struct.Sender.html This improves visual information density (the construct with the logo and crate name is *shorter* than the logo on its own, because it's not square) and navigation clarity (we can now see what clicking the Rust logo does, specifically). Compare this with the layout at [Phoenix's Hexdocs] (which is what this proposal is closely based on), the old proposal on [Internals Discourse] (which always says "Rust standard library" in the sidebar, but doesn't do the side-by-side layout). [Phoenix's Hexdocs]: https://hexdocs.pm/phoenix/1.7.7/overview.html [Internals Discourse]: https://internals.rust-lang.org/t/poc-of-a-new-design-for-the-generated-rustdoc/11018 In newer versions of rustdoc, the crate name and version are always shown in the sidebar, even in subpages. Clicking the crate name does the same thing clicking the logo always did: return you to the crate root. While this actually takes up less screen real estate than the old layout on desktop, it takes up more HTML. It's also a bit more visually complex. I could do what the Internals POC did and keep the vertically stacked layout all the time, instead of doing a horizontal stack where possible. It would take up more screen real estate, though. This design is lifted almost verbatim from Hexdocs. It seems to work for them. [`opentelemetry_process_propagator`], for example, has a long application name. [`opentelemetry_process_propagator`]: https://hexdocs.pm/opentelemetry_process_propagator/OpentelemetryProcessPropagator.html Has anyone written the rationale on why the Rust logo shows up on projects that aren't the standard library? If we turned it off on non-standard crates by default, it would line wrap crate names a lot less often. Or maybe we should encourage crate authors to include their own logo more often? It certainly helps give people a better sense of "place." I'm not sure of anything that directly follows up this one. Plenty of other changes could be made to improve the layout, like * coming up with a less cluttered way to do disclosure (there's a lot of `[-]` on the page) * doing a better job of separating lateral navigation (vec::Vec links to vec::IntoIter) and the table of contents (vec::Vec links to vec::Vec::new) * giving readers more control of how much rustdoc hows them, and giving doc authors more control of how much it generates * better search that reduces the need to browse But those are mostly orthogonal, not future possibilities unlocked by this change. --- src/librustdoc/html/layout.rs | 1 + src/librustdoc/html/render/context.rs | 6 +-- src/librustdoc/html/render/sidebar.rs | 9 ++-- src/librustdoc/html/static/css/rustdoc.css | 57 +++++++++++++++++----- src/librustdoc/html/static/js/main.js | 8 ++- src/librustdoc/html/templates/page.html | 22 ++++++--- src/librustdoc/html/templates/sidebar.html | 3 -- tests/rustdoc-gui/huge-logo.goml | 4 +- tests/rustdoc-gui/sidebar-mobile.goml | 2 +- tests/rustdoc-gui/sidebar.goml | 24 +++++---- tests/rustdoc/crate-version-escape.rs | 2 +- tests/rustdoc/crate-version.rs | 2 +- tests/rustdoc/titles.rs | 3 +- 13 files changed, 95 insertions(+), 48 deletions(-) diff --git a/src/librustdoc/html/layout.rs b/src/librustdoc/html/layout.rs index 8c5871d91264..25ca67db6491 100644 --- a/src/librustdoc/html/layout.rs +++ b/src/librustdoc/html/layout.rs @@ -17,6 +17,7 @@ pub(crate) struct Layout { pub(crate) external_html: ExternalHtml, pub(crate) default_settings: FxHashMap, pub(crate) krate: String, + pub(crate) krate_version: String, /// The given user css file which allow to customize the generated /// documentation theme. pub(crate) css_file_extension: Option, diff --git a/src/librustdoc/html/render/context.rs b/src/librustdoc/html/render/context.rs index 97714afaa458..62c7dbe78eca 100644 --- a/src/librustdoc/html/render/context.rs +++ b/src/librustdoc/html/render/context.rs @@ -534,6 +534,7 @@ impl<'tcx> FormatRenderer<'tcx> for Context<'tcx> { external_html, default_settings, krate: krate.name(tcx).to_string(), + krate_version: cache.crate_version.as_deref().unwrap_or_default().to_string(), css_file_extension: extension_css, scrape_examples_extension: !call_locations.is_empty(), };
