2022-11-03Use `Mode` less.Nicholas Nethercote-7/+7
It's passed to numerous places where we just need an `is_byte` bool. Passing the bool avoids the need for some assertions. Also rename `is_bytes()` as `is_byte()`, to better match `Mode::Byte`, `Mode::ByteStr`, and `Mode::RawByteStr`.
2022-11-02Rollup merge of #103703 - Nilstrieb:flag-recovery-1, r=compiler-errorsDylan DPC-6/+32
Gate some parser recovery behind the check Mainly in `expr.rs`. `may_recover` doesn't do anything useful yet until I implement that on top of #103439. r? `@compiler-errors`
2022-11-01Rollup merge of #103575 - Xiretza:suggestions-style-attr, r=davidtwcoManish Goregaokar-24/+47
Change #[suggestion_*] attributes to use style="..." As discussed [on Zulip](https://rust-lang.zulipchat.com/#narrow/stream/336883-i18n/topic/.23100717.20tool_only_span_suggestion), this changes `#[(multipart_)suggestion_{short,verbose,hidden}(...)]` attributes to plain `#[(multipart_)suggestion(...)]` attributes with a `style = "{short,verbose,hidden}"` parameter. It also adds a new style, `tool-only`, that corresponds to `tool_only_span_suggestion`/`tool_only_multipart_suggestion` and causes the suggestion to not be shown in human-readable output at all. Best reviewed commit-by-commit, there's a bit of noise in there. cc #100717 `@compiler-errors` r? `@davidtwco`
2022-11-01Auto merge of #103217 - mejrs:track, r=eholkbors-0/+2
Track where diagnostics were created. This implements the `-Ztrack-diagnostics` flag, which uses `#[track_caller]` to track where diagnostics are created. It is meant as a debugging tool much like `-Ztreat-err-as-bug`. For example, the following code... ```rust struct A; struct B; fn main(){ let _: A = B; } ``` ...now emits the following error message: ``` error[E0308]: mismatched types --> src\main.rs:5:16 | 5 | let _: A = B; | - ^ expected struct `A`, found struct `B` | | | expected due to this -Ztrack-diagnostics: created at compiler\rustc_infer\src\infer\error_reporting\mod.rs:2275:31 ```

2022-10-27Rollup merge of #103544 - Nilstrieb:no-recovery-pls, r=compiler-errorsMatthias Krüger-2/+30
Add flag to forbid recovery in the parser To start the effort of fixing #103534, this adds a new flag to the parser, which forbids the parser from doing recovery, which it shouldn't do in macros. This doesn't add any new checks for recoveries yet and is just here to bikeshed the names for the functions here before doing more. r? `@compiler-errors`

2022-10-23Auto merge of #103345 - Nilstrieb:diag-flat, r=compiler-errorsbors-199/+185
Flatten diagnostic slug modules This makes it easier to grep for the slugs in the code. See https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Localization.20infra.20interferes.20with.20grepping.20for.20error for more discussion about it. This was mostly done with a few regexes and a bunch of manual work. This also exposes a pretty annoying inconsistency for the extra labels. Some of the extra labels are defined as additional properties in the fluent message (which makes them not prefixed with the crate name) and some of them are new fluent messages themselves (which makes them prefixed with the crate name). I don't know whether we want to clean this up at some point but it's useful to know. r? `@davidtwco`

2022-10-12Rollup merge of #102927 - compiler-errors:let, r=davidtwcoDylan DPC-6/+11
Fix `let` keyword removal suggestion in structs (1.) Fixes a bug where, given this code: ```rust struct Foo { let x: i32, } ``` We were parsing the field name as `let` instead of `x`, which causes issues later on in the type-checking phase. (2.) Also, suggestions for `let: i32` as a field regressed, displaying this extra `help:` which is removed by this PR ``` help: remove the let, the `let` keyword is not allowed in struct field definitions | 2 - let: i32, 2 + : i32, ``` (3.) Makes the suggestion text a bit more succinct, since we don't need to re-explain that `let` is not allowed in this position (since it's in a note that follows). This causes the suggestion to render inline as well. cc `@gimbles,` this addresses a few nits I mentioned in your PR.

2022-10-03Invert `is_top_level` to avoid negation.Nicholas Nethercote-5/+5
2022-10-03Remove `TokenStreamBuilder`.Nicholas Nethercote-37/+20
It's now only used in one function. Also, the "should we glue the tokens?" check is only necessary when pushing a `TokenTree::Token`, not when pushing a `TokenTree::Delimited`. As part of this, we now do the "should we glue the tokens?" check immediately, which avoids having look back at the previous token. It also puts all the logic dealing with token gluing in a single place.
