2015-01-05Reformat metadata for exported macrosKeegan McAllister-0/+4
Instead of copy-pasting the whole macro_rules! item from the original .rs file, we serialize a separate name, attributes list, and body, the latter as pretty-printed TTs. The compilation of macro_rules! macros is decoupled somewhat from the expansion of macros in item position. This filters out comments, and facilitates selective imports.
2015-01-05Rename macro_escape to macro_useKeegan McAllister-1/+2
In the future we want to support #[macro_use(foo, bar)] mod macros; but it's not an essential part of macro reform. Reserve the syntax for now.

2015-01-04serialize: Use assoc types + less old_orphan_checkAlex Crichton-0/+17
This commit moves the libserialize crate (and will force the hand of the rustc-serialize crate) to not require the `old_orphan_check` feature gate as well as using associated types wherever possible. Concretely, the following changes were made: * The error type of `Encoder` and `Decoder` is now an associated type, meaning that these traits have no type parameters. * The `Encoder` and `Decoder` type parameters on the `Encodable` and `Decodable` traits have moved to the corresponding method of the trait. This movement alleviates the dependency on `old_orphan_check` but implies that implementations can no longer be specialized for the type of encoder/decoder being implemented. Due to the trait definitions changing, this is a: [breaking-change]
2015-01-05Change `&` pat to only work with &T, and `&mut` with &mut T.Huon Wilson-2/+7
This implements RFC 179 by making the pattern `&<pat>` require matching against a variable of type `&T`, and introducing the pattern `&mut <pat>` which only works with variables of type `&mut T`. The pattern `&mut x` currently parses as `&(mut x)` i.e. a pattern match through a `&T` or a `&mut T` that binds the variable `x` to have type `T` and to be mutable. This should be rewritten as follows, for example, for &mut x in slice.iter() { becomes for &x in slice.iter() { let mut x = x; Due to this, this is a [breaking-change] Closes #20496.

2015-01-03Remove deprecated functionalityAlex Crichton-10/+2
This removes a large array of deprecated functionality, regardless of how recently it was deprecated. The purpose of this commit is to clean out the standard libraries and compiler for the upcoming alpha release. Some notable compiler changes were to enable warnings for all now-deprecated command line arguments (previously the deprecated versions were silently accepted) as well as removing deriving(Zero) entirely (the trait was removed). The distribution no longer contains the libtime or libregex_macros crates. Both of these have been deprecated for some time and are available externally.

2015-01-03auto merge of #20154 : P1start/rust/qualified-assoc-type-generics, ↵bors-34/+10
r=nikomatsakis This modifies `Parser::eat_lt` to always split up `<<`s, instead of doing so only when a lifetime name followed or the `force` parameter (now removed) was `true`. This is because `Foo<<TYPE` is now a valid start to a type, whereas previously only `Foo<<LIFETIME` was valid. This is a [breaking-change]. Change code that looks like this: ```rust let x = foo as bar << 13; ``` to use parentheses, like this: ```rust let x = (foo as bar) << 13; ``` Closes #17362.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-2/+6
This commit is an implementation of [RFC 503][rfc] which is a stabilization story for the prelude. Most of the RFC was directly applied, removing reexports. Some reexports are kept around, however: * `range` remains until range syntax has landed to reduce churn. * `Path` and `GenericPath` remain until path reform lands. This is done to prevent many imports of `GenericPath` which will soon be removed. * All `io` traits remain until I/O reform lands so imports can be rewritten all at once to `std::io::prelude::*`. This is a breaking change because many prelude reexports have been removed, and the RFC can be consulted for the exact list of removed reexports, as well as to find the locations of where to import them. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0503-prelude-stabilization.md [breaking-change] Closes #20068

Since runtime is removed, rust has no tasks anymore and everything is moving from being task-* to thread-*. Let’s rename TaskRng as well! This is a breaking change. If a breaking change for consistency is not desired, feel free to close.

2014-12-30Remove ExprSlice by hacking the compilerNick Cameron-4/+11
[breaking-change] The `mut` in slices is now redundant. Mutability is 'inferred' from position. This means that if mutability is only obvious from the type, you will need to use explicit calls to the slicing methods.
