2015-01-05Rename macro_escape to macro_useKeegan McAllister-1/+1
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.
2015-01-05Implement macro re-exportKeegan McAllister-0/+2
Fixes #17103.
2015-01-05Replace LetSyntaxTT with MacroRulesTTKeegan McAllister-1/+1
The implementation of LetSyntaxTT was specialized to macro_rules! in various ways. This gets rid of the false generality and simplifies the code.

These are in scope for 1.0, and this is good to e.g. find as many bugs as possible.

2015-01-02std: Stabilize the prelude moduleAlex Crichton-0/+2
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
2015-01-01std: Enforce Unicode in fmt::WriterAlex Crichton-9/+3
This commit is an implementation of [RFC 526][rfc] which is a change to alter the definition of the old `fmt::FormatWriter`. The new trait, renamed to `Writer`, now only exposes one method `write_str` in order to guarantee that all implementations of the formatting traits can only produce valid Unicode. [rfc]: https://github.com/rust-lang/rfcs/blob/master/text/0526-fmt-text-writer.md One of the primary improvements of this patch is the performance of the `.to_string()` method by avoiding an almost-always redundant UTF-8 check. This is a breaking change due to the renaming of the trait as well as the loss of the `write` method, but migration paths should be relatively easy: * All usage of `write` should move to `write_str`. If truly binary data was being written in an implementation of `Show`, then it will need to use a different trait or an altogether different code path. * All usage of `write!` should continue to work as-is with no modifications. * All usage of `Show` where implementations just delegate to another should continue to work as-is. [breaking-change] Closes #20352

Uses the same approach as https://github.com/rust-lang/rust/pull/17286 (and subsequent changes making it more correct), where the visitor will skip any pieces of the AST that are from "foreign code", where the spans don't line up, indicating that that piece of code is due to a macro expansion. If this breaks your code, read the error message to determine which feature gate you should add to your crate. Closes #18102 [breaking-change]

If this breaks your code, read the error message to determine which feature gate you should add to your crate, and bask in the knowledge that your code won't mysteriously break should you try to use the 1.0 release.

2014-12-30auto merge of #20307 : ↵bors-46/+57
nikomatsakis/rust/assoc-types-normalization-extend-bound, r=nrc Rewrite associated types to use projection rather than dummy type parameters. This closes almost every (major) open issue, but I'm holding off on that until the code has landed and baked a bit. Probably it should have more tests, as well, but I wanted to get this landed as fast as possible so that we can collaborate on improving it. The commit history is a little messy, particularly the merge commit at the end. If I get some time, I might just "reset" to the beginning and try to carve up the final state into logical pieces. Let me know if it seems hard to follow. By far the most crucial commit is "Implement associated type projection and normalization." r? @nick29581

2014-12-30auto merge of #19941 : alexcrichton/rust/issue-19767, r=brsonbors-2/+3
This commit adds support for the compiler to distinguish between different forms of lookup paths in the compiler itself. Issue #19767 has some background on this topic, as well as some sample bugs which can occur if these lookup paths are not separated. This commits extends the existing command line flag `-L` with the same trailing syntax as the `-l` flag. Each argument to `-L` can now have a trailing `:all`, `:native`, `:crate`, or `:dependency`. This suffix indicates what form of lookup path the compiler should add the argument to. The `dependency` lookup path is used when looking up crate dependencies, the `crate` lookup path is used when looking for immediate dependencies (`extern crate` statements), and the `native` lookup path is used for probing for native libraries to insert into rlibs. Paths with `all` are used for all of these purposes (the default). The default compiler lookup path (the rustlib libdir) is by default added to all of these paths. Additionally, the `RUST_PATH` lookup path is added to all of these paths. Closes #19767

2014-12-29std: Second pass stabilization for `comm`Alex Crichton-1/+1
This commit is a second pass stabilization for the `std::comm` module, performing the following actions: * The entire `std::comm` module was moved under `std::sync::mpsc`. This movement reflects that channels are just yet another synchronization primitive, and they don't necessarily deserve a special place outside of the other concurrency primitives that the standard library offers. * The `send` and `recv` methods have all been removed. * The `send_opt` and `recv_opt` methods have been renamed to `send` and `recv`. This means that all send/receive operations return a `Result` now indicating whether the operation was successful or not. * The error type of `send` is now a `SendError` to implement a custom error message and allow for `unwrap()`. The error type contains an `into_inner` method to extract the value. * The error type of `recv` is now `RecvError` for the same reasons as `send`. * The `TryRecvError` and `TrySendError` types have had public reexports removed of their variants and the variant names have been tweaked with enum namespacing rules. * The `Messages` iterator is renamed to `Iter` This functionality is now all `#[stable]`: * `Sender` * `SyncSender` * `Receiver` * `std::sync::mpsc` * `channel` * `sync_channel` * `Iter` * `Sender::send` * `Sender::clone` * `SyncSender::send` * `SyncSender::try_send` * `SyncSender::clone` * `Receiver::recv` * `Receiver::try_recv` * `Receiver::iter` * `SendError` * `RecvError` * `TrySendError::{mod, Full, Disconnected}` * `TryRecvError::{mod, Empty, Disconnected}` * `SendError::into_inner` * `TrySendError::into_inner` This is a breaking change due to the modification of where this module is located, as well as the changing of the semantics of `send` and `recv`. Most programs just need to rename imports of `std::comm` to `std::sync::mpsc` and add calls to `unwrap` after a send or a receive operation. [breaking-change]

2014-12-27save-analysis: emit names of items that a glob import actually imports.Nick Cameron-5/+17
There is also some work here to make resolve a bit more stable - it no longer overwrites a specific import with a glob import. [breaking-change] Import shadowing of single/list imports by globs is now forbidden. An interesting case is where a glob import imports a re-export (`pub use`) of a single import. This still counts as a single import for the purposes of shadowing .You can usually fix any bustage by re-ordering such imports. A single import may still shadow (override) a glob import or the prelude.

This prints out a transformed version of the input source code where every function body is replaced with `loop { }`. All such bodies are (1.) trivial and (2.) guaranteed to pass the type-checker in a valid compiler; therefore they make very nice input to start with when narrowing down a bug exposed by a large test input (such as librustc itself).
