2018-02-07libsyntax/ext: trailing commas in builtin macrosMichael Lamparski-2/+4
Most notably this changes 'syntax::ext::base::get_single_str_from_tts' to accept a trailing comma, and revises the documentation so that this aspect is not surprising. I made this change under the understanding that this crate is private rustc implementation detail (I hope this is correct!). After reviewing all call sites, I believe the revised semantics are closer to the intended spirit of the function.

2018-01-30Rollup merge of #47603 - mark-i-m:markim_comments_0000, r=jseyfriedkennytm-39/+173
Run rustfmt and add doc comments to libsyntax/ext/tt/quoted.rs I was already going to try to understand this code to try to implement rust-lang/rfcs#2298. I figured I would put that knowledge into comments and share... This PR contains _no changes_ to the code itself -- just formatting and comments. I'm not sure what the best way to do this is. I plan to make more such PR for other files, but I figured it would have fewer conflicts if I do it file by file...

Point at unused arguments for format string Avoid overlapping spans by only pointing at the arguments that are not being used in the argument string. Enable libsyntax to have diagnostics with multiple primary spans by accepting `Into<MultiSpan>` instead of `Span`. Partially addresses #41850.

2017-12-28Resurrecting #33135Michael Hewson-7/+16
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.

1. Change the return type of `expand_invoc()` and its subroutines to `Option<Expansion>` from `Expansion`. 2. Return `None` when expanding a derive invocation if the item cannot have derive on it (in `expand_derive_invoc()`).

2017-12-22Auto merge of #46732 - estebank:silence-recovered-blocks, r=petrochenkovbors-0/+1
Do not emit type errors on recovered blocks When a parse error occurs on a block, the parser will recover and create a block with the statements collected until that point. Now a flag stating that a recovery has been performed in this block is propagated so that the type checker knows that the type of the block (which will be identified as `()`) shouldn't be checked against the expectation to reduce the amount of irrelevant diagnostic errors shown to the user. Fix #44579.

2017-12-22Rollup merge of #46858 - QuietMisdreavus:external-doc-error, r=estebankkennytm-7/+11
tweaks and fixes for doc(include) This PR makes a handful of changes around `#[doc(include="file.md")]` (https://github.com/rust-lang/rust/issues/44732): * Turns errors when loading files into full errors. This matches the original RFC text. * Makes the `missing_docs` lint check for `#[doc(include="file.md")]` as well as regular `#[doc="text"]` attributes. * Loads files included by `#[doc(include="file.md")]` into dep-info, mirroring the behavior of `include_str!()` and friends. * Adds or modifies tests to check for all of these.
2017-12-21Add GenericParam, refactor Generics in ast, hir, rustdocJonas Platte-1/+1
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.

2017-11-14avoid the pprust infrastructure in macro expansionAriel Ben-Yehuda-3/+24
This changes macro expansion to format the path of a macro directly instead of usng the pprust infrastructure. The pprust infrastructure tries to perform line-breaking in a slow fashion, which is undesired when formatting the path of a macro. This should to speed up expansion by a fair amount (I saw 20% on a profiler on `rustc_mir`, and 50% of the time marked as "expansion" in the profiler/time-passes is actually spent loading dependencies).
