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.

2018-01-15Point at unused arguments for format stringEsteban Küber-19/+19
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`.

2017-12-26Do not expand a derive invocation when derive is not allowedSeiichi Uchida-0/+12
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()`).

2017-05-13Support #[allow] etc logic on a per macro levelest31-1/+1
This commit extends the current unused macro linter to support directives like #[allow(unused_macros)] or #[deny(unused_macros)] directly next to the macro definition, or in one of the modules the macro is inside. Before, we only supported such directives at a per crate level, due to the crate's NodeId being passed to session.add_lint. We also had to implement handling of the macro's NodeId in the lint visitor.
