2020-08-05Show backtrace numbers in backtrace whenever more than one is involvedAaron Hill-2/+2
Previously, we only displayed 'frame' numbers in a macro backtrace when more than two frames were involved. This commit should help make backtrace more readable, since these kinds of messages can quickly get confusing.
2020-06-25emitter: column width defaults to 140David Wood-3/+7
This commit modifies the column width computation in the emitter when `termize::dimensions` returns `None` so that it uses the default value of 140 (which is used in UI testing currently) instead of `usize::MAX` which just ends up causing overflows in later computations. This is hard to test but appears to produce the same output as using saturating functions instead. Signed-off-by: David Wood <david@davidtw.co>
2020-04-24Replace filter_map().next() calls with find_map()Josh Stone-13/+10
These are semantically the same, but `find_map()` is more concise.

(clippy::single_match) Makes code more compact and reduces nestig.
2020-03-20Revised span-to-lines conversion to produce an empty vec on DUMMY_SP.Felix S. Klock II-1/+1
This required revising some of the client code to stop relying on the returned set of lines being non-empty.

2020-03-10Store `TokenStream` in `rmeta::MacroDef`.Mazdak Farrokhzad-8/+8
This removes a hack from `load_macro_untracked` in which parsing is used.

2020-01-30Rollup merge of #68626 - Zoxc:termize, r=estebankDylan DPC-1/+1
Use termize instead of term_size `termize` is a fork of `term_size` which uses `winapi` 0.3 instead of 0.2. This is a step towards removing the `winapi` 0.2 dependency. r? @Mark-Simulacrum

2020-01-05Handle multiple error fix suggestions carefulyLaurent Bonnans-5/+13
The existing code seems to assume that substitutions spans are disjoint, which is not always the case. In the example: pub trait AAAA {} pub trait B {} pub trait C {} pub type T<P: AAAA + B + C> = P; , we get three substituions starting from ':' and ending respectively at the end of each trait token. With the former offset calculation, this would cause `underline_start` to eventually become negative before being converted to `usize`... The new version may report erroneous results for non perfectly overlapping substitutions but I don't know if such examples exist. Alternatively, we could detect these cases and trim out overlapping substitutions.

2019-11-15Remove SourceMapper traitMark Rousskov-12/+13
SourceMap is now in the root of all rustc-specific crates, syntax_pos, so there's no need for the trait object to decouple the dependencies between librustc_errors and libsyntax as was needed previously.

https://github.com/rust-lang/rust/pull/64272 replaced `DiagnosticBuilder` with `Diagnostic` in some places. This commit just renames the DB variable from `db` to `diag` where it wasn't renamed.
