2018-04-10Auto merge of #49390 - Zoxc:sync-syntax, r=michaelwoeristerbors-29/+18
More thread-safety changes r? @michaelwoerister
2018-04-09in which `!` is suggested for erroneous identifier `not`Zack M. Davis-2/+52
Impressing confused Python users with magical diagnostics is perhaps worth this not-grossly-unreasonable (only 40ish lines) extra complexity in the parser? Thanks to Vadim Petrochenkov for guidance. This resolves #46836.
2018-04-09don't suggest placing code in block if next token is open-braceZack M. Davis-0/+5
Thanks to the inestimably inimitable Esteban "Estebank" Küber for pointing this out. This is relevant to #46836.

2018-04-05Rollup merge of #49350 - abonander:macros-in-extern, r=petrochenkovAlex Crichton-55/+71
Expand macros in `extern {}` blocks This permits macro and proc-macro and attribute invocations (the latter only with the `proc_macro` feature of course) in `extern {}` blocks, gated behind a new `macros_in_extern` feature. A tracking issue is now open at #49476 closes #48747

2018-04-02Auto merge of #49124 - abonander:attr-macro-stmt-expr, r=abonanderbors-0/+3
Expand Attributes on Statements and Expressions This enables attribute-macro expansion on statements and expressions while retaining the `stmt_expr_attributes` feature requirement for attributes on expressions. closes #41475 cc #38356 @petrochenkov @jseyfried r? @nrc
2018-04-02Expand attribute macros on statements and expressions.Austin Bonander-0/+3

2018-04-01Auto merge of #49478 - Phlosioneer:fix-windows-file-not-found, r=petrochenkovbors-1/+1
Fix escaped backslash in windows file not found message When a module is declared, but no matching file exists, rustc gives an error like `help: name the file either foo.rs or foo/mod.rs inside the directory "src/bar"`. However, at on windows, the backslash was double-escaped when naming the directory. It did this because the string was printed in debug mode (`"{:?}"`) to surround it with quotes. However, it should just be printed like any other directory in an error message and surrounded by escaped quotes, rather than relying on the debug print to add quotes (`"\"{}\""`). I also checked the test suite to see if this output is being correctly tested. It's not - it only tests up to the word "directory". Presumably this is so that the test is not dependent on its exact position in the source tree. I don't know a better way to test this, unless the test suite supports regex?

libsyntax: Remove obsolete.rs This little piece of infra is obsolete (ha-ha) and is unlikely to be used in the future, even if new obsolete syntax appears.

2018-03-15Disallow &a..=b and box a..=b in pattern.kennytm-2/+27
They are disallowed because they have different precedence than expressions. I assume parenthesis in pattern will be soon stabilized and thus write that as suggestion directly.

(Meanwhile, a couple of parse-fail tests are moved to UI tests so that the reader can see the new output, and an existing UI test is given a more evocative name.)
