2018-05-22rustc: Correctly pretty-print macro delimitersAlex Crichton-54/+50
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 ```

2018-05-03Auto merge of #50030 - flip1995:rfc2103, r=petrochenkovbors-16/+21
Implement tool_attributes feature (RFC 2103) cc #44690 This is currently just a rebased and compiling (hopefully) version of #47773. Let's see if travis likes this. I will add the implementation for `tool_lints` this week.

2018-04-18Auto merge of #49993 - nnethercote:shrink-Token, r=alexcrichtonbors-3/+3
Change the hashcounts in raw `Lit` variants from usize to u16. This reduces the size of `Token` from 32 bytes to 24 bytes on 64-bit platforms.

2018-04-05Rollup merge of #49350 - abonander:macros-in-extern, r=petrochenkovAlex Crichton-0/+9
Expand macros in `extern {}` blocks This permits macro and proc-macro and attribute invocations (the latter only with the `proc_macro` feature of course) in `extern {}` blocks, gated behind a new `macros_in_extern` feature. A tracking issue is now open at #49476 closes #48747

AST/HIR: Add a separate structure for labels
2018-01-23Adds support for immovable generators. Move checking of invalid borrows ↵John Kåre Alsaker-1/+10

2018-01-13Remove `impl Foo for ..` in favor of `auto trait Foo`leonardo.yvens-12/+0
No longer parse it. Remove AutoTrait variant from AST and HIR. Remove backwards compatibility lint. Remove coherence checks, they make no sense for the new syntax. Remove from rustdoc.
2017-12-28Resurrecting #33135Michael Hewson-0/+1
Started rebasing @sgrif's PR #33135 off of current master. (Well, actually merging it into a new branch based off current master.) The following files still need to be fixed or at least reviewed: - `src/libsyntax/ext/tt/macro_parser.rs`: calls `Parser::parse_lifetime`, which doesn't exist anymore - `src/libsyntax/parse/parser.rs`: @sgrif added an error message to `Parser::parse_lifetime`. Code has since been refactored, so I just took it out for now. - `src/libsyntax/ext/tt/transcribe.rs`: This code has been refactored bigtime. Not sure whether @sgrif's changes here are still necessary. Took it out for this commit.
2017-12-21Add GenericParam, refactor Generics in ast, hir, rustdocJonas Platte-67/+44
The Generics now contain one Vec of an enum for the generic parameters, rather than two separate Vec's for lifetime and type parameters. Additionally, places that previously used Vec<LifetimeDef> now use Vec<GenericParam> instead.
