2019-08-17initial implementation of or-pattern parsingDan Robertson-35/+12
Initial implementation of parsing or-patterns e.g., `Some(Foo | Bar)`. This is a partial implementation of RFC 2535.

2019-08-15`Ident::with_empty_ctxt` -> `Ident::with_dummy_span`Vadim Petrochenkov-3/+3
`Ident` has had a full span rather than just a `SyntaxContext` for a long time now.

Some more libsyntax::attr cleanup Much smaller patch than the last one, mostly just finishing up by removing some Span arguments. r? @petrochenkov

2019-08-03Auto merge of #63180 - varkor:trait-alias-impl-trait, r=Centrilbors-5/+9
Change opaque type syntax from `existential type` to type alias `impl Trait` This implements a new feature gate `type_alias_impl_trait` (this is slightly different from the originally proposed feature name, but matches what has been used in discussion since), deprecating the old `existential_types` feature. The syntax for opaque types has been changed. In addition, the "existential" terminology has been replaced with "opaque", as per previous discussion and the RFC. This makes partial progress towards implementing https://github.com/rust-lang/rust/issues/63063. r? @Centril

2019-07-28Rollup merge of #62550 - Centril:rest-patterns, r=petrochenkovMazdak Farrokhzad-47/+9
Implement RFC 2707 + Parser recovery for range patterns Implement https://github.com/rust-lang/rfcs/pull/2707. - Add a new basic syntactic pattern form `ast::PatKind::Rest` (parsed as `..` or `DOTDOT`) and simplify `ast::PatKind::{Slice, Tuple, TupleStruct}` as a result. - Lower `ast::PatKind::Rest` in combination with the aforementioned `PatKind` variants as well as `PatKind::Ident`. The HIR remains unchanged for now (may be advisable to make slight adjustments later). - Refactor `parser.rs` wrt. parsing sequences and lists of things in the process. - Add parser recovery for range patterns of form `X..`, `X..=`, `X...`, `..Y`, `..=Y`, and `...Y`. This should make it easy to actually support these patterns semantically later if we so desire. cc https://github.com/rust-lang/rust/issues/62254 r? @petrochenkov

Fixes https://github.com/rust-lang/rust/issues/62628
2019-07-15pprust: Remove the box from `print_tts`Vadim Petrochenkov-2/+4
Wrap the whole attribute into a box instead
2019-07-15pprust: Use `print_mac_common` for delimited token groupsVadim Petrochenkov-27/+33

2019-07-15pprust: Move some methods to the `PrintState` traitVadim Petrochenkov-135/+132

2019-07-10Use constant instead of magic numberMark Rousskov-1/+1
2019-07-10Remove needless indent argumentsMark Rousskov-11/+8
We're always indenting by INDENT_UNIT anyway
2019-07-10Move pp::Printer helpers to direct implMark Rousskov-42/+12
2019-07-10Rename is_bol -> is_beginning_of_lineMark Rousskov-9/+4
Also moves it to pp::Printer from PrintState.
2019-07-10Remove needless indirection in bcloseMark Rousskov-6/+2
2019-07-10Drop length from Token::StringMark Rousskov-1/+1
It was always set to the string's length
2019-07-10Remove is_begin/is_end functions from PrintStateMark Rousskov-16/+4
These are somewhat ambiguous (beginning/end of what?) so it's better to inline their one use into the code.
2019-07-10Move pp::Printer out field to owned StringMark Rousskov-19/+13
This enforces that eof() must be called to get the String out, and generally is better from an API perspective. No users of pretty printing pre-allocate the buffer.
