2015-11-27Auto merge of #30064 - fhartwig:macro-suggestions, r=sanxiynbors-0/+88
Fixes #13677 This does the same sort of suggestion for misspelt macros that we already do for misspelt identifiers. Example. Compiling this program: ```rust macro_rules! foo { ($e:expr) => ( $e ) } fn main() { fob!("hello!"); } ``` gives the following error message: ``` /Users/mcp/temp/test.rs:7:5: 7:8 error: macro undefined: 'fob!' /Users/mcp/temp/test.rs:7 fob!("hello!"); ^~~ /Users/mcp/temp/test.rs:7:5: 7:8 help: did you mean `foo`? /Users/mcp/temp/test.rs:7 fob!("hello!"); ``` I had to move the levenshtein distance function into libsyntax for this. Maybe this should live somewhere else (some utility crate?), but I couldn't find a crate to put it in that is imported by libsyntax and the other rustc crates.

Part of https://github.com/rust-lang/rust/issues/29935 The deprecation lint is still called "deprecated", so people can continue using `#[allow(deprecated)]` and similar things.

2015-11-17Auto merge of #29766 - oli-obk:impl_item, r=nikomatsakisbors-38/+37
[breaking change] I'm not sure if those renames are ok. [TokenType::Tt* to TokenType::*](https://github.com/rust-lang/rust/pull/29582) was obvious, but for all those Item-enums it's less obvious to me what the right way forward is due to the underscore.

2015-11-13Move the panicking parse functions out of the parserKyle Mayes-50/+52
Since these functions are only used by the AST quoting syntax extensions, they should be there instead of in the parser.

2015-11-12Auto merge of #29780 - KyleMayes:quote-ext, r=nrcbors-1/+86
This is my first code contribution to Rust, so I'm sure there are some issues with the changes I've made. I've added the `quote_arg!`, `quote_block!`, `quote_path!`, and `quote_meta_item!` quasiquoting macros. From my experience trying to build AST in compiler plugins, I would like to be able to build any AST piece with a quasiquoting macro (e.g., `quote_struct_field!` or `quote_variant!`) and then use those AST pieces in other quasiquoting macros, but this pull request just adds some of the low-hanging fruit. I'm not sure if these additions are desirable, and I'm sure these macros can be implemented in an external crate if not.
2015-11-12Auto merge of #29544 - Ryman:reduce_doc_warnings, r=steveklabnikbors-17/+24
Did this alphabetically, so I didn't see [how `std` was doing things](https://dxr.mozilla.org/rust/source/src/libstd/lib.rs#215) till I was nearly finished. If you prefer to add crate-level-whitelists like std instead of test-level, I can rebase with that strategy. A number of these commits can probably be dropped as the crates don't have much to test, and are deprecated. Let me know which if any to drop! (can also squash after review if desired) r? @steveklabnik

2015-11-10Auto merge of #29725 - aturon:lang-features, r=huonwbors-45/+59
This commit adds issue numbers to the vast majority of active feature gates. The few that are left without issues are rustc/runtime-internal features that are essentially private APIs. Closes #28244 r? @huonw
