2018-01-12Auto merge of #46551 - jseyfried:improve_legacy_modern_macro_interaction, r=nrcbors-0/+39
macros: improve 1.0/2.0 interaction This PR supports using unhygienic macros from hygienic macros without breaking the latter's hygiene. ```rust // crate A: #[macro_export] macro_rules! m1 { () => { f(); // unhygienic: this macro needs `f` in its environment fn g() {} // (1) unhygienic: `g` is usable outside the macro definition } } // crate B: #![feature(decl_macro)] extern crate A; use A::m1; macro m2() { fn f() {} // (2) m1!(); // After this PR, `f()` in the expansion resolves to (2), not (3) g(); // After this PR, this resolves to `fn g() {}` from the above expansion. // Today, it is a resolution error. } fn test() { fn f() {} // (3) m2!(); // Today, `m2!()` can see (3) even though it should be hygienic. fn g() {} // Today, this conflicts with `fn g() {}` from the expansion, even though it should be hygienic. } ``` Once this PR lands, you can make an existing unhygienic macro hygienic by wrapping it in a hygienic macro. There is an [example](https://github.com/rust-lang/rust/pull/46551/commits/b766fa887dc0e4b923a38751fe4d570e35a75710) of this in the tests. r? @nrc

2017-08-18Auto merge of #43832 - huntiep:compiler-desugaring-enum, r=nikomatsakisbors-3/+23
Implement CompilerDesugaringKind enum This is the first step outlined in #35946. I think that the variants of `CompilerDesugaringKind` should be changed, I didn't know what the official names for `...` and `<-` are. I'm not to sure how tests for the compiler work, but I would imagine that tests should be added such that `Symbol::intern(s) == CompilerDesugaringKind::from(s).as_symbol()` for valid `s`.
