2022-05-11Remove some unnecessary invisible delimiter checks.Nicholas Nethercote-2/+1
These seem to have no useful effect... they don't seem useful from a code inspection point of view, and they affect anything in the test suite.
2022-04-28Rollup merge of #96433 - petrochenkov:delim, r=nnethercoteDylan DPC-42/+43
rustc_ast: Harmonize delimiter naming with `proc_macro::Delimiter` Compiler cannot reuse `proc_macro::Delimiter` directly due to extra impls, but can at least use the same naming. After this PR the only difference between these two enums is that `proc_macro::Delimiter::None` is turned into `token::Delimiter::Invisible`. It's my mistake that the invisible delimiter is called `None` on stable, during the stabilization I audited the naming and wrote the docs, but missed the fact that the `None` naming gives a wrong and confusing impression about what this thing is. cc https://github.com/rust-lang/rust/pull/96421 r? ``@nnethercote``

2022-04-23Better handle too many `#` recovery in raw strEsteban Küber-9/+34
Point at all the unnecessary trailing `#`. Better handle interaction with outer attributes when `;` is missing. Fix #95030.
2022-04-05errors: implement fallback diagnostic translationDavid Wood-14/+22
This commit updates the signatures of all diagnostic functions to accept types that can be converted into a `DiagnosticMessage`. This enables existing diagnostic calls to continue to work as before and Fluent identifiers to be provided. The `SessionDiagnostic` derive just generates normal diagnostic calls, so these APIs had to be modified to accept Fluent identifiers. In addition, loading of the "fallback" Fluent bundle, which contains the built-in English messages, has been implemented. Each diagnostic now has "arguments" which correspond to variables in the Fluent messages (necessary to render a Fluent message) but no API for adding arguments has been added yet. Therefore, diagnostics (that do not require interpolation) can be converted to use Fluent identifiers and will be output as before.
2022-04-05span: move `MultiSpan`David Wood-3/+3
`MultiSpan` contains labels, which are more complicated with the introduction of diagnostic translation and will use types from `rustc_errors` - however, `rustc_errors` depends on `rustc_span` so `rustc_span` cannot use types like `DiagnosticMessage` without dependency cycles. Introduce a new `rustc_error_messages` crate that can contain `DiagnosticMessage` and `MultiSpan`. Signed-off-by: David Wood <david.wood@huawei.com>

Suggest `i += 1` when we see `i++` or `++i` Closes #83502 (for `i++` and `++i`; `--i` should be covered by #82987, and `i--` is tricky to handle). This is a continuation of #83536. r? `@estebank`

2022-03-27Fix from rebaseNoah Lev-5/+5
I changed the test functions to be `pub` rather than called from a `main` function too, for easier future modification of tests.

Fixes #95208
2022-03-23Fix rustfix panic on testNoah Lev-1/+1
`run-rustfix` applies all suggestions regardless of their Applicability. There's a flag, `rustfix-only-machine-applicable`, that does what it says, but then the produced `.fixed` file would have invalid code from the suggestions that weren't applied. So, I moved the cases of postfix increment, in which case multiple suggestions are given, to the `-notfixed` test, which does not run rustfix. I also changed the Applicability to Unspecified since MaybeIncorrect requires that the code be valid, even if it's incorrect.

This records that the suggestions are mutually-exclusive (i.e., only one should be applied).

* Recover from invalid `'label: ` before block. * Make suggestion to enclose statements in a block multipart. * Point at `match`, `while`, `loop` and `unsafe` keywords when failing to parse their expression. * Do not suggest `{ ; }`. * Do not suggest `|` when very unlikely to be what was wanted (in `let` statements).
