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.
2017-12-28Auto merge of #47013 - topecongiro:issue-46655, r=petrochenkovbors-79/+103
Do not expand a derive invocation when derive is not allowed Closes #46655. The first commit is what actually closes #46655. The second one is just a refactoring I have done while waiting on a test.

2017-12-26Do not expand a derive invocation when derive is not allowedSeiichi Uchida-79/+103
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).

2017-09-21only set non-ADT derive error once per attribute, not per traitZack M. Davis-0/+18
A slight eccentricity of this change is that now non-ADT-derive errors prevent derive-macro-not-found errors from surfacing (see changes to the gating-of-derive compile-fail tests). Resolves #43927.

2017-08-21Auto merge of #43540 - petrochenkov:pathrelax, r=nikomatsakisbors-3/+1
syntax: Relax path grammar TLDR: Accept the disambiguator `::` in "type" paths (`Type::<Args>`), accept the disambiguator `::` before parenthesized generic arguments (`Fn::(Args)`). The "turbofish" disambiguator `::<>` in expression paths is a necessary evil required for path parsing to be both simple and to give reasonable results. Since paths in expressions usually refer to values (but not necessarily, e.g. `Struct::<u8> { field: 0 }` is disambiguated, but refers to a type), people often consider `::<>` to be inherent to *values*, and not *expressions* and want to write disambiguated paths for values even in contexts where disambiguation is not strictly necessary, for example when a path is passed to a macro `m!(Vec::<i32>::new)`. The problem is that currently, if the disambiguator is not *required*, then it's *prohibited*. This results in confusion - see https://github.com/rust-lang/rust/issues/41740, https://internals.rust-lang.org/t/macro-path-uses-novel-syntax/5561. This PR makes the disambiguator *optional* instead of prohibited in contexts where it's not strictly required, so people can pass paths to macros in whatever form they consider natural (e.g. disambiguated form for value paths). This PR also accepts the disambiguator in paths with parenthesized arguments (`Fn::(Args)`) for consistency and to simplify testing of stuff like https://github.com/rust-lang/rust/pull/41856#issuecomment-301219194. Closes https://github.com/rust-lang/rust/issues/41740 cc @rust-lang/lang r? @nikomatsakis

Fix include! in doc tests By making the path relative to the current file. Fixes #43153 [breaking-change] - if you use `include!` inside a doc test, you'll need to change the path to be relative to the current file rather than relative to the working directory.
