2019-05-29Rollup merge of #61024 - petrochenkov:proctest, r=nikomatsakisMazdak Farrokhzad-525/+475
tests: Centralize proc macros commonly used for testing Many proc macros in `ui\proc-macro\auxiliary` were doing same things. (I added a fair share of those myself.) Now commonly used macros (empty, identity, etc) are collected in one place - `ui\proc-macro\auxiliary\test-macros.rs`.
2019-05-25Reword malformed attribute input diagnosticsEsteban Küber-45/+43
- Handle empty `cfg_attr` attribute - Reword empty `derive` attribute error - Use consistend error message: "malformed `attrname` attribute input" - Provide suggestions when possible - Move note/help to label/suggestion - Use consistent wording "ill-formed" -> "malformed" - Move diagnostic logic out of parser
2019-05-24Tweak macro parse errors when reaching EOF during macro call parseEsteban Küber-2/+2
- Add detail on origin of current parser when reaching EOF and stop saying "found <eof>" and point at the end of macro calls - Handle empty `cfg_attr` attribute - Reword empty `derive` attribute error

2019-04-05Include trailing comma in multiline Debug representationDavid Tolnay-80/+80
This commit changes the behavior of Formatter::debug_struct, debug_tuple, debug_list, debug_set, and debug_map to render trailing commas in {:#?} mode, which is the dominant style in modern Rust code. Before: Language { name: "Rust", trailing_commas: false } After: Language { name: "Rust", trailing_commas: true, }
2019-03-25Auto merge of #59258 - euclio:suggestions-filter-crate, r=oli-obkbors-1/+1
filter suggestions from extern prelude Fixes #59027. Modifies the candidate gathering code to call `filter_fn` on extern crates, which causes them to be filtered out when looking for a type.

2019-02-05Auto merge of #57973 - davidtwco:issue-52891, r=estebankbors-9/+8
Add suggestion for duplicated import. Fixes #52891. This PR adds a suggestion when a import is duplicated (ie. the same name is used twice trying to import the same thing) to remove the second import.

add typo suggestion to unknown attribute error Provides a suggestion using Levenshtein distance to suggest built-in attributes and attribute macros. Fixes #49270.
2019-01-28Unused variable suggestions on all patterns.David Wood-1/+1
This commit extends existing suggestions to prefix unused variable bindings in match arms with an underscore so that it applies to all patterns in a match arm.

2019-01-16Auto merge of #57321 - petrochenkov:atokens, r=nikomatsakisbors-32/+32
Implement basic input validation for built-in attributes Correct top-level shape (`#[attr]` vs `#[attr(...)]` vs `#[attr = ...]`) is enforced for built-in attributes, built-in attributes must also fit into the "meta-item" syntax (aka the "classic attribute syntax"). For some subset of attributes (found by crater run), errors are lowered to deprecation warnings. NOTE: This PR previously included https://github.com/rust-lang/rust/pull/57367 as well.

2018-12-28Auto merge of #57155 - petrochenkov:dcrate3, r=dtolnaybors-0/+113
Resolve `$crate`s for pretty-printing at more appropriate time Doing it in `BuildReducedGraphVisitor` wasn't a good idea, identifiers wasn't actually visited half of the time. As a result some `$crate`s weren't resolved and were therefore pretty-printed as `$crate` literally, which turns into two tokens during re-parsing of the pretty-printed text. Now we are visiting and resolving `$crate` identifiers in an item right before sending that item to a proc macro attribute or derive. Fixes https://github.com/rust-lang/rust/issues/57089
