resolve: Improve candidate search for unresolved macro suggestions Use same scope visiting machinery for both collecting suggestion candidates and actually resolving the names. The PR is better read in per-commit fashion with whitespace changes ignored (the first commit in particular moves some code around). This should be the last pre-requisite for https://github.com/rust-lang/rust/pull/62086. r? @davidtwco

2019-07-18resolve: Use `feature(custom_attribute)` fallback only if the feature is enabledVadim Petrochenkov-75/+34
Normally `#![feature(...)]` shouldn't change behavior, but custom attributes in particular are in the process of retirement, and we should not produce a message telling to enable them. It also helps with unifying diagnostics for unresolved macros.

Add a test for the issue resolved by removing `resolve_macro_path` Add a test making sure that extern prelude entries introduced from an opaque macro are not visible anywhere, even it that macro Fix test output after rebase
2019-07-11resolve/expand: Catch macro kind mismatches early in resolveVadim Petrochenkov-16/+72
This way we are processing all of them in a single point, rather than separately for each syntax extension kind. Also, the standard expected/found wording is used.
2019-07-11resolve: Make proc macro stubs less stubbyVadim Petrochenkov-29/+47
Create real working and registered (even if dummy) `SyntaxExtension`s for them. This improves error recovery and allows to avoid all special cases for proc macro stubs (except for the error on use, of course). The introduced dummy `SyntaxExtension`s can be used for any other inappropriately resolved macros as well.
2019-07-10Rollup merge of #62393 - petrochenkov:notto-disu, r=Mark-SimulacrumMazdak Farrokhzad-8/+153
Fix pretty-printing of `$crate` (take 4) Pretty-print `$crate` as `crate` or `crate_name` in unstructured tokens like `a $crate c` in `foo!(a $crate c)`, but only if those tokens are printed as a part of AST pretty-printing, rather than as a standalone token stream. Fixes https://github.com/rust-lang/rust/issues/62325 Previous iterations - https://github.com/rust-lang/rust/pull/56647, https://github.com/rust-lang/rust/pull/57155, https://github.com/rust-lang/rust/pull/57915.

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

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, }

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.
