|\ | | | | | | | | | | | | | | | | | | | | | | 1848: Parse `..` as a full pattern r=matklad a=ecstatic-morse Resolves #1479. This PR implements [RFC 2707](https://github.com/rust-lang/rfcs/pull/2707) in the parser. It introduces a new `DotDotPat` AST node modeled on `PlaceholderPat` and changes the parsing of tuple and slice patterns to conform to the RFC. Notably, this PR does *not* change the resulting AST when `..` appears in a struct pattern (e.g. `Struct { a, b: c, .. }`). I *think* this is the behavior mandated by RFC 2707, but someone should confirm this. Co-authored-by: Dylan MacKenzie <[email protected]>

One further improvement can be to detect if macro accepts no parameters and place the cursor differently for this case. * Add an exclamation mark to the macro completion label This helps to distinguish macros from other completion items and also allows to show only macros in completion if you type `!`: <img width="722" alt="image" src="https://user-images.githubusercontent.com/2690773/64736987-8b8ea180-d4f4-11e9-8355-2ce4f83b7aa8.png"> <img width="732" alt="image" src="https://user-images.githubusercontent.com/2690773/64737214-ffc94500-d4f4-11e9-946e-1ba2db1c7fb1.png"> Additionally, automatic formatting hooks had adjusted two `help.rs` files, I've added them as a last commit to the PR even though they are not really related.

|/ / | | | | | | | | | | | | Parser has the invariant that `{}` are balanced. Previous code tried (unsucesfuly) maintain the same invariant for `$()` as well, but it was done in a rather ad-hoc manner: it's not at all obvious that it is possible to maintain both invariants!

In `rustc`, the macro scope behave exactly the same as type and value scope. It is valid that macros, types and values having exact the same name, and a `use` statement will import all of them. This happened to module `alloc::vec` and macro `alloc::vec!`. So `Either` is not suitable here. There is a trap that not only does `#[macro_use]` import all `#[macro_export] macro_rules`, but also imports all macros `use`d in the crate root. In other words, it just _imports all macros in the module scope of crate root_. (Visibility of `use` doesn't matter.) And it also happened to `libstd` which has `use alloc_crate::vec;` in crate root to re-export `alloc::vec`, which it both a module and a macro. The current implementation of `#[macro_use] extern crate` doesn't work here, so that is why only macros directly from `libstd` like `dbg!` work, while `vec!` from `liballoc` doesn't. This PR fixes this. Another point is that, after some tests, I figure out that _`macro_rules` does NOT define macro in current module scope at all_. It defines itself in legacy textual scope. And if `#[macro_export]` is given, it also is defined ONLY in module scope of crate root. (Then being `macro_use`d, as mentioned above) (Well, the nightly [Declarative Macro 2.0](https://github.com/rust-lang/rust/issues/39412) simply always define in current module scope only, just like normal items do. But it is not yet supported by us) After this PR, in my test, all non-builtin macros are resolved now. (Hover text for documentation is available) So it fixes #1688 . Since compiler builtin macros are marked as `#[rustc_doc_only_macro]` instead of `#[macro_export]`, we can simply tweak the condition to let it resolved, but it may cause expansion error. Some critical notes are also given in doc-comments. <img width="447" alt="Screenshot_20190909_223859" src="https://user-images.githubusercontent.com/14816024/64540366-ac1ef600-d352-11e9-804f-566ba7559206.png"> Co-authored-by: uHOOCCOOHu <[email protected]>
