2018-09-27Auto merge of #52319 - tinco:issue_12590, r=pnkfelixbors-1/+3
Track whether module declarations are inline (fixes #12590) To track whether module declarations are inline I added a field `inline: bool` to `ast::Mod`. The main use case is for pretty to know whether it should render the items associated with the module, but perhaps there are use cases for this information to not be forgotten in the AST.

2018-09-01Auto merge of #53815 - F001:if-let-guard, r=petrochenkovbors-1/+11
refactor match guard This is the first step to implement RFC 2294: if-let-guard. Tracking issue: https://github.com/rust-lang/rust/issues/51114 The second step should be introducing another variant `IfLet` in the Guard enum. I separated them into 2 PRs for the convenience of reviewers. r? @petrochenkov

Implement try block expressions I noticed that `try` wasn't a keyword yet in Rust 2018, so... ~~Fix​es https://github.com/rust-lang/rust/issues/52604~~ That was fixed by PR https://github.com/rust-lang/rust/pull/53135 cc https://github.com/rust-lang/rust/issues/31436 https://github.com/rust-lang/rust/issues/50412

2018-06-26inclusive range syntax lint (`...` → `..=`)Zack M. Davis-2/+2
Our implementation ends up changing the `PatKind::Range` variant in the AST to take a `Spanned<RangeEnd>` instead of just a `RangeEnd`, because the alternative would be to try to infer the span of the range operator from the spans of the start and end subexpressions, which is both hideous and nontrivial to get right (whereas getting the change to the AST right was a simple game of type tennis). This is concerning #51043.

2018-06-21Parse async fn header.Without Boats-5/+3
This is gated on edition 2018 & the `async_await` feature gate. The parser will accept `async fn` and `async unsafe fn` as fn items. Along the same lines as `const fn`, only `async unsafe fn` is permitted, not `unsafe async fn`.The parser will not accept `async` functions as trait methods. To do a little code clean up, four fields of the function type struct have been merged into the new `FnHeader` struct: constness, asyncness, unsafety, and ABI. Also, a small bug in HIR printing is fixed: it previously printed `const unsafe fn` as `unsafe const fn`, which is grammatically incorrect.

rustc: Correctly pretty-print macro delimiters This commit updates the `Mac_` AST structure to keep track of the delimiters that it originally had for its invocation. This allows us to faithfully pretty-print macro invocations not using parentheses (e.g. `vec![...]`). This in turn helps procedural macros due to #43081. Closes #50840

2018-05-13Macros: Add a 'literal' fragment specifierDan Aloni-0/+1
Implements RFC 1576. See: https://github.com/rust-lang/rfcs/blob/master/text/1576-macros-literal-matcher.md Changes are mostly in libsyntax, docs, and tests. Feature gate is enabled for 1.27.0. Many thanks to Vadim Petrochenkov for following through code reviews and suggestions. Example: ````rust macro_rules! test_literal { ($l:literal) => { println!("literal: {}", $l); }; ($e:expr) => { println!("expr: {}", $e); }; } fn main() { let a = 1; test_literal!(a); test_literal!(2); test_literal!(-3); } ``` Output: ``` expr: 1 literal: 2 literal: -3 ```
