[tiny] parser: `macro_rules` is a weak keyword r? @Centril

2020-02-15Remove extra debug print in unreachable!David Ross-2/+1
2020-02-15Keep better fix suggestion if type ascription is likely unintendedDavid Ross-9/+15
2020-02-15Type ascription outputs a Type, not CastDavid Ross-1/+3
Previously this just errored out on all usages of type ascription, which isn't helpful.
2020-02-15Refactor out error case & apply suggestions.David Ross-20/+42
This is almost entirely refactoring and message changing, with the single behavioral change of panicking for unexpected output.
2020-02-15Parse & reject postfix operators after castsDavid Ross-2/+39
This adds parsing for expressions like 'x as Ty[0]' which will immediately error out, but still give the rest of the parser a valid parse tree to continue.
2020-02-15reject assoc statics & extern consts during parsingMazdak Farrokhzad-1/+26
2020-02-15Record proc macro harness order for use during metadata deserializationAaron Hill-0/+2
Fixes #68690 When we generate the proc macro harness, we now explicitly recorder the order in which we generate entries. We then use this ordering data to deserialize the correct proc-macro-data from the crate metadata.

2020-02-15parser: `macro_rules` is a weak keywordVadim Petrochenkov-2/+2
2020-02-14Suggest a comma if a struct initializer field fails to parseAaron Hill-1/+7
Currently, we emit a "try adding a comma" suggestion if a comma is missing in a struct definition. However, we emit no such suggestion if a comma is missing in a struct initializer. This commit adds a "try adding a comma" suggestion when we don't find a comma during the parsing of a struct initializer field. The change to `src/test/ui/parser/removed-syntax-with-1.stderr` isn't great, but I don't see a good way of avoiding it.

2020-02-13parser: introduce `parse_item_kind` as central `ItemInfo` logic.Mazdak Farrokhzad-192/+156
this also extracts macro item parsers.

use new span for better diagnostics.
2020-02-13Constness -> enum Const { Yes(Span), No }Mazdak Farrokhzad-46/+43
Same idea for `Unsafety` & use new span for better diagnostics.

Account for type params on method without parentheses Account for those type parameters in the structured suggestion when forgetting to call method: ``` error[E0615]: attempted to take value of method `collect` on type `std::vec::IntoIter<_>` --> $DIR/method-missing-parentheses.rs:2:32 | LL | let _ = vec![].into_iter().collect::<usize>; | ^^^^^^^--------- | | | help: use parentheses to call the method: `collect::<usize>()` ```

change an instance of span_bug() to struct_span_err() to avoid ICE After #67148, the `span_bug()` in `parse_ty_tuple_or_parens()` is reachable because `parse_paren_comma_seq()` can return an `Ok()` even in cases where it encounters an error. This pull request prevents an ICE in such cases by replacing the `span_bug()` with `struct_span_error()`. Fixes #68890.
