2015-01-06rollup merge of #20653: alexcrichton/entry-unstableAlex Crichton-1/+1
There's been some debate over the precise form that these APIs should take, and they've undergone some changes recently, so these APIs are going to be left unstable for now to be fleshed out during the next release cycle.
2015-01-07Cleanup and followup to PR #17830: parsing changesPiotr Czarnecki-26/+44

2015-01-06core: split into fmt::Show and fmt::StringSean McArthur-2/+2
fmt::Show is for debugging, and can and should be implemented for all public types. This trait is used with `{:?}` syntax. There still exists #[derive(Show)]. fmt::String is for types that faithfully be represented as a String. Because of this, there is no way to derive fmt::String, all implementations must be purposeful. It is used by the default format syntax, `{}`. This will break most instances of `{}`, since that now requires the type to impl fmt::String. In most cases, replacing `{}` with `{:?}` is the correct fix. Types that were being printed specifically for users should receive a fmt::String implementation to fix this. Part of #20013 [breaking-change]

2015-01-06syntax: implement 'macro input future proofing'Corey Richardson-8/+140
See RFC 550 (https://github.com/rust-lang/rfcs/pull/550) for the motivation and details. If this breaks your code, add one of the listed tokens after the relevant non-terminal in your matcher. [breaking-change]
2015-01-05Modernize macro_rules! invocationsKeegan McAllister-2/+2
macro_rules! is like an item that defines a macro. Other items don't have a trailing semicolon, or use a paren-delimited body. If there's an argument for matching the invocation syntax, e.g. parentheses for an expr macro, then I think that applies more strongly to the *inner* delimiters on the LHS, wrapping the individual argument patterns.
2015-01-05Move #[macro_reexport] to extern crateKeegan McAllister-41/+0
2015-01-05Reformat metadata for exported macrosKeegan McAllister-19/+10
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.

2015-01-05Replace LetSyntaxTT with MacroRulesTTKeegan McAllister-16/+5
The implementation of LetSyntaxTT was specialized to macro_rules! in various ways. This gets rid of the false generality and simplifies the code.

2014-11-17Switch to purely namespaced enumsSteven Fackler-0/+4
This breaks code that referred to variant names in the same namespace as their enum. Reexport the variants in the old location or alter code to refer to the new locations: ``` pub enum Foo { A, B } fn main() { let a = A; } ``` => ``` pub use self::Foo::{A, B}; pub enum Foo { A, B } fn main() { let a = A; } ``` or ``` pub enum Foo { A, B } fn main() { let a = Foo::A; } ``` [breaking-change]

2014-10-30collections: Enable IndexMut for some collectionsAlex Crichton-6/+4
This commit enables implementations of IndexMut for a number of collections, including Vec, RingBuf, SmallIntMap, TrieMap, TreeMap, and HashMap. At the same time this deprecates the `get_mut` methods on vectors in favor of using the indexing notation. cc #18424
2014-10-30Use common variants for open and close delimitersBrendan Zabarauskas-16/+9
This common representation for delimeters should make pattern matching easier. Having a separate `token::DelimToken` enum also allows us to enforce the invariant that the opening and closing delimiters must be the same in `ast::TtDelimited`, removing the need to ensure matched delimiters when working with token trees.
2014-10-29Rename fail! to panic!Steve Klabnik-3/+3
https://github.com/rust-lang/rfcs/pull/221 The current terminology of "task failure" often causes problems when writing or speaking about code. You often want to talk about the possibility of an operation that returns a Result "failing", but cannot because of the ambiguity with task failure. Instead, you have to speak of "the failing case" or "when the operation does not succeed" or other circumlocutions. Likewise, we use a "Failure" header in rustdoc to describe when operations may fail the task, but it would often be helpful to separate out a section describing the "Err-producing" case. We have been steadily moving away from task failure and toward Result as an error-handling mechanism, so we should optimize our terminology accordingly: Result-producing functions should be easy to describe. To update your code, rename any call to `fail!` to `panic!` instead. Assuming you have not created your own macro named `panic!`, this will work on UNIX based systems: grep -lZR 'fail!' . | xargs -0 -l sed -i -e 's/fail!/panic!/g' You can of course also do this by hand.

This should be clearer, and fits in better with the `TTNonterminal` variant. Renames: - `TTTok` -> `TTToken` - `TTDelim` -> `TTDelimited` - `TTSeq` -> `TTSequence`
2014-10-26Add Span and separate open/close delims to TTDelimBrendan Zabarauskas-37/+37
This came up when working [on the gl-rs generator extension](https://github.com/bjz/gl-rs/blob/990383de801bd2e233159d5be07c9b5622827620/src/gl_generator/lib.rs#L135-L146). The new definition of `TTDelim` adds an associated `Span` that covers the whole token tree and enforces the invariant that a delimited sequence of token trees must have an opening and closing delimiter. A `get_span` method has also been added to `TokenTree` type to make it easier to implement better error messages for syntax extensions.
