2022-12-12Properly calculate best failure in macro matchingNilstrieb-0/+4
Previously, we used spans. This was not good. Sometimes, the span of the token that failed to match may come from a position later in the file which has been transcribed into a token stream way earlier in the file. If precisely this token fails to match, we think that it was the best match because its span is so high, even though other arms might have gotten further in the token stream. We now try to properly use the location in the token stream.

propagate the error from parsing enum variant to the parser and emit out While parsing enum variant, the error message always disappear Because the error message that emit out is from main error of parser The information of enum variant disappears while parsing enum variant with error We only check the syntax of expecting token, i.e, in case https://github.com/rust-lang/rust/issues/103869 It will error it without telling the message that this error is from pasring enum variant. Propagate the sub-error from parsing enum variant to the main error of parser by chaining it with map_err Check the sub-error before emitting the main error of parser and attach it.

2022-12-05Parameterise `Parser::{recover_unclosed_char,handle_missing_lit}`.Nicholas Nethercote-30/+49
These two methods both produce a `MetaItemLit`, and then some of the call sites convert the `MetaItemLit` to a `token::Lit` with `as_token_lit`. This commit parameterises these two methods with a `mk_lit_char` closure, which can be used to produce either `MetaItemLit` or `token::Lit` directly as necessary.
2022-12-04Rollup merge of #105141 - ohno418:fix-ice-on-invalid-var-decl-in-macro-call, ↵Matthias Krüger-19/+24
r=compiler-errors Fix ICE on invalid variable declarations in macro calls This fixes ICE that happens with invalid variable declarations in macro calls like: ```rust macro_rules! m { ($s:stmt) => {} } m! { var x } m! { auto x } m! { mut x } ``` Found this is because of not collecting tokens on recovery, so I changed to force collect them. Fixes https://github.com/rust-lang/rust/issues/103529.

2022-12-01While parsing enum variant, the error message always disappearYiming Lei-1/+8
Because the error message that emit out is from main error of parser The information of enum variant disappears while parsing enum variant with error We only check the syntax of expecting token, i.e, in case #103869 It will error it without telling the message that this error is from pasring enum variant.

2022-12-02Remove `token::Lit` from `ast::MetaItemLit`.Nicholas Nethercote-6/+7
`token::Lit` contains a `kind` field that indicates what kind of literal it is. `ast::MetaItemLit` currently wraps a `token::Lit` but also has its own `kind` field. This means that `ast::MetaItemLit` encodes the literal kind in two different ways. This commit changes `ast::MetaItemLit` so it no longer wraps `token::Lit`. It now contains the `symbol` and `suffix` fields from `token::Lit`, but not the `kind` field, eliminating the redundancy.
2022-12-01rustc_ast_lowering: Stop lowering imports into multiple itemsVadim Petrochenkov-1/+1
Lower them into a single item with multiple resolutions instead. This also allows to remove additional `NodId`s and `DefId`s related to those additional items.
2022-11-29Avoid unnecessary `MetaItem`/`Attribute` conversions.Nicholas Nethercote-17/+26
`check_builtin_attribute` calls `parse_meta` to convert an `Attribute` to a `MetaItem`, which it then checks. However, many callers of `check_builtin_attribute` start with a `MetaItem`, and then convert it to an `Attribute` by calling `cx.attribute(meta_item)`. This `MetaItem` to `Attribute` to `MetaItem` conversion is silly. This commit adds a new function `check_builtin_meta_item`, which can be called instead from these call sites. `check_builtin_attribute` also now calls it. The commit also renames `check_meta` as `check_attr` to better match its arguments.

2022-11-22Rollup merge of #104559 - nnethercote:split-MacArgs, r=petrochenkovMatthias Krüger-62/+61
Split `MacArgs` in two. `MacArgs` is an enum with three variants: `Empty`, `Delimited`, and `Eq`. It's used in two ways: - For representing attribute macro arguments (e.g. in `AttrItem`), where all three variants are used. - For representing function-like macros (e.g. in `MacCall` and `MacroDef`), where only the `Delimited` variant is used. In other words, `MacArgs` is used in two quite different places due to them having partial overlap. I find this makes the code hard to read. It also leads to various unreachable code paths, and allows invalid values (such as accidentally using `MacArgs::Empty` in a `MacCall`). This commit splits `MacArgs` in two: - `DelimArgs` is a new struct just for the "delimited arguments" case. It is now used in `MacCall` and `MacroDef`. - `AttrArgs` is a renaming of the old `MacArgs` enum for the attribute macro case. Its `Delimited` variant now contains a `DelimArgs`. Various other related things are renamed as well. These changes make the code clearer, avoids several unreachable paths, and disallows the invalid values. r? `@petrochenkov`
