2017-05-31Extend the unused macro lint to macros 2.0est31-4/+7
2017-05-27Auto merge of #42103 - jorendorff:master, r=estebankbors-3/+12
trace_macro: Show both the macro call and its expansion. #42072. See #42072 for the initial motivation behind this. The change is not the minimal fix, but I want this behavior almost every time I use `trace_macros`.

2017-05-24Rollup merge of #42071 - nrc:parse-mods, r=nikomatsakisMark Simulacrum-4/+8
Add an option to the parser to avoid parsing out of line modules This is useful if parsing from stdin or a String and don't want to try and read in a module from another file. Instead we just leave a stub in the AST.

2017-05-17Auto merge of #41961 - kennytm:fix-35829, r=petrochenkovbors-36/+20
Fix #35829 (`quote!()` does not handle `br#"…"#`) Fix issue #35829 (syntax extension's `quote_expr!()` does not handle `b"…"` and proc_macro's `quote!()` does not handle `r#"…"#`) * Handles `b"…"`, `br#"…"#` and `...` for `quote_expr!()`. * Refactored the match statement to allow it to complain loudly on any unhandled token. * Similarly, proc_macro's `quote!()` did not handle `br#"…"#` or `r#"…"#`, so this PR fixes it too.

2017-05-16Rollup merge of #41957 - llogiq:clippy-libsyntax, r=petrochenkovMark Simulacrum-84/+90
Fix some clippy warnings in libsyntax This is mostly removing stray ampersands, needless returns and lifetimes. Basically a lot of small changes.
2017-05-16Auto merge of #41907 - est31:macro_unused, r=jseyfriedbors-3/+11
Add lint for unused macros Addresses parts of #34938, to add a lint for unused macros. We now output warnings by default when we encounter a macro that we didn't use for expansion. Issues to be resolved before this PR is ready for merge: - [x] fix the NodeId issue described above - [x] remove all unused macros from rustc and the libraries or set `#[allow(unused_macros)]` next to them if they should be kept for some reason. This is needed for successful boostrap and bors to accept the PR. -> #41934 - [x] ~~implement the full extent of #34938, that means the macro match arm checking as well.~~ *let's not do this for now*

2017-05-13Support #[allow] etc logic on a per macro levelest31-3/+7
This commit extends the current unused macro linter to support directives like #[allow(unused_macros)] or #[deny(unused_macros)] directly next to the macro definition, or in one of the modules the macro is inside. Before, we only supported such directives at a per crate level, due to the crate's NodeId being passed to session.add_lint. We also had to implement handling of the macro's NodeId in the lint visitor.

2017-05-08Rollup merge of #41520 - estebank:trace-macro, r=nikomatsakisCorey Farwell-5/+19
Use diagnostics for trace_macro instead of println When using `trace_macro`, use `span_label`s instead of `println`: ```rust note: trace_macro --> $DIR/trace-macro.rs:14:5 | 14 | println!("Hello, World!"); | ^^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: expands to `println! { "Hello, World!" }` = note: expands to `print! { concat ! ( "Hello, World!" , "\n" ) }` ``` Fix #22597.

2017-03-22Introduce HirId, a replacement for NodeId after lowering to HIR.Michael Woerister-11/+3
HirId has a more stable representation than NodeId, meaning that modifications to one item don't influence (part of) the IDs within other items. The other part is a DefIndex for which there already is a way of stable hashing and persistence. This commit introduces the HirId type and generates a HirId for every NodeId during HIR lowering, but the resulting values are not yet used anywhere, except in consistency checks.

2017-03-19Auto merge of #40346 - jseyfried:path_and_tokenstream_attr, r=nrcbors-109/+91
`TokenStream`-based attributes, paths in attribute and derive macro invocations This PR - refactors `Attribute` to use `Path` and `TokenStream` instead of `MetaItem`. - supports macro invocation paths for attribute procedural macros. - e.g. `#[::foo::attr_macro] struct S;`, `#[cfg_attr(all(), foo::attr_macro)] struct S;` - supports macro invocation paths for derive procedural macros. - e.g. `#[derive(foo::Bar, super::Baz)] struct S;` - supports arbitrary tokens as arguments to attribute procedural macros. - e.g. `#[foo::attr_macro arbitrary + tokens] struct S;` - supports using arbitrary tokens in "inert attributes" with derive procedural macros. - e.g. `#[derive(Foo)] struct S(#[inert arbitrary + tokens] i32);` where `#[proc_macro_derive(Foo, attributes(inert))]` r? @nrc
