2019-10-02syntax: improve parameter without type suggestionsDavid Wood-8/+25
This commit improves the suggestions provided when function parameters do not have types: - A new suggestion is added for arbitrary self types, which suggests adding `self: ` before the type. - Existing suggestions are now provided when a `<` is found where a `:` was expected (previously only `,` and `)` or trait items), this gives suggestions in the case where the unnamed parameter type is generic in a free function. - The suggestion that a type name be provided (e.g. `fn foo(HashMap<u32>)` -> `fn foo(HashMap: TypeName<u32>)`) will no longer occur when a `<` was found instead of `:`. - The ident will not be used for recovery when a `<` was found instead of `:`.

2019-10-01Rollup merge of #64910 - Centril:params-cleanup, r=petrochenkovMazdak Farrokhzad-563/+495
syntax: cleanup param, method, and misc parsing Do some misc cleanup of the parser: - Method and parameter parsing is refactored. - A parser for `const | mut` is introduced that https://github.com/rust-lang/rust/pull/64588 can reuse. - Some other misc parsing. Next up in a different PR: - ~Implementing https://github.com/rust-lang/rust/issues/64252.~ -- maybe some other time... - Heavily restructuring up `item.rs` which is a mess (hopefully, no promises ^^). r? @petrochenkov
2019-10-01Rollup merge of #64907 - alexreg:tidy-up, r=Mark-SimulacrumMazdak Farrokhzad-1/+1
A small amount of tidying-up factored out from PR #64648 As requested by @Mark-Simulacrum, I put this in a separate commit to make it easier to review. (As far as I can tell, no violations of the policy here, and they are simply in a separate PR because they're not directly related to the import of that PR.) r? @Mark-Simulacrum
2019-10-01Rollup merge of #64887 - Centril:recover-trailing-vert, r=estebankMazdak Farrokhzad-26/+79
syntax: recover trailing `|` in or-patterns Fixes https://github.com/rust-lang/rust/issues/64879. For example (this also shows that we are sensitive to the typo `||`): ``` error: a trailing `|` is not allowed in an or-pattern --> $DIR/remove-leading-vert.rs:33:11 | LL | A || => {} | - ^^ help: remove the `||` | | | while parsing this or-pattern starting here | = note: alternatives in or-patterns are separated with `|`, not `||` ``` r? @estebank

2019-09-29Rollup merge of #64894 - Centril:fix-64682, r=petrochenkovMazdak Farrokhzad-76/+41
syntax: fix dropping of attribute on first param of non-method assocated fn Fixes #64682. The general idea is that we bake parsing of `self` into `parse_param_general` and then we just use standard list parsing. Overall, this simplifies the parsing and makes it more consistent. r? @petrochenkov cc @c410-f3r

2019-09-27Auto merge of #64813 - varkor:node-to-kind, r=Centrilbors-73/+73
Rename `*.node` to `*.kind`, and `hair::Pattern*` to `hair::Pat*` In both `ast::Expr` and `hir::Expr`: - Rename `Expr.node` to `Expr.kind`. - Rename `Pat.node` to `Pat.kind`. - Rename `ImplItem.node` to `ImplItem.kind`. - Rename `Lit.node` to `Lit.kind`. - Rename `TraitItem.node` to `TraitItem.kind`. - Rename `Ty.node` to `Ty.kind`. - Rename `Stmt.node` to `Stmt.kind`. - Rename `Item.node` to `Item.kind`. - Rename `ForeignItem.node` to `ForeignItem.kind`. - Rename `MetaItem.node` to `MetaItem.kind`. Also: - Rename `hair::FieldPattern` to `hair::FieldPat`. - Rename `hair::PatternKind` to `hair::PatKind`. - Rename `hair::PatternRange` to `hair::PatRange`. - Rename `PatternContext` to `PatCtxt`. - Rename `PatternTypeProjection` to `PatTyProj`. - Rename `hair::Pattern` to `hair::Pat`. These two sets of changes are grouped together to aid with merging. The only changes are renamings. r? @petrochenkov
