chore: Improve how the other suggestions message gets rendered Note: This change is part of my ongoing work to use `annotate-snippets` as `rustc`'s emitter This change started as a way to remove some specialty code paths from `annotate-snippets`, by making the "and {} other candidates" message get rendered like a secondary message with no level, but turned into a fix for the message's Unicode output. Before this change, when using the Unicode output, the other suggestions message would get rendered outside of the main suggestion block, making it feel disconnected from what it was referring to. This change makes it so that the message is on the last line of the block, aligning its rendering with other secondary messages, and making it clear what the message is referring to. Before: ``` error[E0433]: failed to resolve: use of undeclared type `IntoIter` ╭▸ $DIR/issue-82956.rs:28:24 │ LL │ let mut iter = IntoIter::new(self); │ ━━━━━━━━ use of undeclared type `IntoIter` ╰╴ help: consider importing one of these structs ╭╴ LL + use std::array::IntoIter; ├╴ LL + use std::collections::binary_heap::IntoIter; ├╴ LL + use std::collections::btree_map::IntoIter; ├╴ LL + use std::collections::btree_set::IntoIter; ╰╴ and 9 other candidates ``` After: ``` error[E0433]: failed to resolve: use of undeclared type `IntoIter` ╭▸ $DIR/issue-82956.rs:28:24 │ LL │ let mut iter = IntoIter::new(self); │ ━━━━━━━━ use of undeclared type `IntoIter` ╰╴ help: consider importing one of these structs ╭╴ LL + use std::array::IntoIter; ├╴ LL + use std::collections::binary_heap::IntoIter; ├╴ LL + use std::collections::btree_map::IntoIter; ├╴ LL + use std::collections::btree_set::IntoIter; │ ╰ and 9 other candidates ```

2025-03-14Do not suggest using `-Zmacro-backtrace` for builtin macrosEsteban Küber-4/+10
For macros that are implemented on the compiler, we do *not* mention the `-Zmacro-backtrace` flag. This includes `derive`s and standard macros.

2025-03-07Fix multiline span start special caseEsteban Küber-1/+1
2025-03-07Refactor `emitter` to better account for unicode chars when trimmingEsteban Küber-78/+99
Change the way that underline positions are calculated by delaying using the "visual" column position until the last possible moment, instead using the "file"/byte position in the file, and then calculating visual positioning as late as possible. This should make the underlines more resilient to non-1-width unicode chars. Unfortunately, as part of this change (which fixes some visual bugs) comes with the loss of some eager tab codepoint handling, but the output remains legible despite some minor regression on the "margin trimming" logic.
2025-03-07On long spans, trim the middle of them to make them fit in the terminal widthEsteban Küber-0/+27
When encountering a single line span that is wider than the terminal, we keep context at the start and end of the span but otherwise remove the code from the middle. This is somewhat independent from whether the left and right margins of the output have been trimmed as well. ``` error[E0308]: mismatched types --> $DIR/long-span.rs:6:15 | LL | ... = [0, 0, 0, 0, ..., 0, 0]; | ^^^^^^^^^^^^^...^^^^^^^ expected `u8`, found `[{integer}; 1681]` ``` Address part of #137680 (missing handling of the long suggestion). Fix #125581.
2025-03-07Remove highlighting of spans on `-Zteach`Esteban Küber-11/+0
`-Zteach` is perma-unstable, barely used, the highlighting logic buggy and the flag being passed around is tech-debt. We should likely remove `-Zteach` in its entirely.

Couple of changes to run rustc in miri This is not the full set of patches required to run rustc in miri, but it is the fast majority of the changes to rustc itself. There is also a change to the jobserver crate necessary and on arm64 a change to the memchr crate. Running rustc in miri has already found some UB: https://github.com/rust-lang/rust/pull/136579 cc https://github.com/rust-lang/rust/issues/135870#issuecomment-2612470540

2024-12-20Rollup merge of #134366 - harrisonkaiser:no-break-space, r=davidtwcoDianQK-2/+8
Fix logical error with what text is considered whitespace. There appears to be a logical issue around what counts as leading white-space. There is code which does a subtraction assuming that no errors will be reported inside the leading whitespace. However we compute the length of that whitespace with std::char::is_whitespace and not rustc_lexer::is_whitespace. The former will include a no-break space while later will excluded it. We can only safely make the assumption that no errors will be reported in whitespace if it is all "Rust Standard" whitespace. Indeed an error does occur in unicode whitespace if it contains a no-break space. In that case the subtraction will cause a ICE (for a compiler in debug mode) as described in https://github.com/rust-lang/rust/issues/132918.

2024-12-12Tweak multispan renderingEsteban Küber-2/+6
Consider comments and bare delimiters the same as an "empty line" for purposes of hiding rendered code output of long multispans. This results in more aggressive shortening of rendered output without losing too much context, specially in `*.stderr` tests that have "hidden" comments.
