2016-03-07implement the `?` operatorJorge Aparicio-0/+4
The `?` postfix operator is sugar equivalent to the try! macro, but is more amenable to chaining: `File::open("foo")?.metadata()?.is_dir()`. `?` is accepted on any *expression* that can return a `Result`, e.g. `x()?`, `y!()?`, `{z}?`, `(w)?`, etc. And binds more tightly than unary operators, e.g. `!x?` is parsed as `!(x?)`. cc #31436
2016-03-07syntax: Always pretty print a newline after doc commentsErick Tryzelaar-1/+2
Before this patch, code that had a doc comment as the first line, as in: ```rust /// Foo struct Foo; ``` Was pretty printed into: ```rust ///Foostruct Foo; ``` This makes sure that that there is always a trailing newline after a doc comment. Closes #31722

2016-01-28libsyntax: fix pretty printing of macro with bracesTomasz Miąsko-5/+2
Pretty printing of macro with braces but without terminated semicolon removed more boxes from stack than it put there, resulting in panic. This fixes the issue #30731.
2016-01-26Auto merge of #31120 - alexcrichton:attribute-deny-warnings, r=brsonbors-1/+0
This commit removes the `-D warnings` flag being passed through the makefiles to all crates to instead be a crate attribute. We want these attributes always applied for all our standard builds, and this is more amenable to Cargo-based builds as well. Note that all `deny(warnings)` attributes are gated with a `cfg(stage0)` attribute currently to match the same semantics we have today
2016-01-26Fix warnings during testsAlex Crichton-1/+0
The deny(warnings) attribute is now enabled for tests so we need to weed out these warnings as well.

2015-12-19Auto merge of #30184 - petrochenkov:ascr, r=nikomatsakisbors-1/+6
This PR is a rebase of the original PR by @eddyb https://github.com/rust-lang/rust/pull/21836 with some unrebasable parts manually reapplied, feature gate added + type equality restriction added as described below. This implementation is partial because the type equality restriction is applied to all type ascription expressions and not only those in lvalue contexts. Thus, all difficulties with detection of these contexts and translation of coercions having effect in runtime are avoided. So, you can't write things with coercions like `let slice = &[1, 2, 3]: &[u8];`. It obviously makes type ascription less useful than it should be, but it's still much more useful than not having type ascription at all. In particular, things like `let v = something.iter().collect(): Vec<_>;` and `let u = t.into(): U;` work as expected and I'm pretty happy with these improvements alone.
