made `parser::Parser::expect_lifetime` public, so it can be called from `macro_parser::parse_nt`
2017-12-28Resurrecting #33135Michael Hewson-0/+1
Started rebasing @sgrif's PR #33135 off of current master. (Well, actually merging it into a new branch based off current master.) The following files still need to be fixed or at least reviewed: - `src/libsyntax/ext/tt/macro_parser.rs`: calls `Parser::parse_lifetime`, which doesn't exist anymore - `src/libsyntax/parse/parser.rs`: @sgrif added an error message to `Parser::parse_lifetime`. Code has since been refactored, so I just took it out for now. - `src/libsyntax/ext/tt/transcribe.rs`: This code has been refactored bigtime. Not sure whether @sgrif's changes here are still necessary. Took it out for this commit.
2017-08-30Make fields of `Span` privateVadim Petrochenkov-3/+4
2017-08-21Auto merge of #43540 - petrochenkov:pathrelax, r=nikomatsakisbors-3/+1
syntax: Relax path grammar TLDR: Accept the disambiguator `::` in "type" paths (`Type::<Args>`), accept the disambiguator `::` before parenthesized generic arguments (`Fn::(Args)`). The "turbofish" disambiguator `::<>` in expression paths is a necessary evil required for path parsing to be both simple and to give reasonable results. Since paths in expressions usually refer to values (but not necessarily, e.g. `Struct::<u8> { field: 0 }` is disambiguated, but refers to a type), people often consider `::<>` to be inherent to *values*, and not *expressions* and want to write disambiguated paths for values even in contexts where disambiguation is not strictly necessary, for example when a path is passed to a macro `m!(Vec::<i32>::new)`. The problem is that currently, if the disambiguator is not *required*, then it's *prohibited*. This results in confusion - see https://github.com/rust-lang/rust/issues/41740, https://internals.rust-lang.org/t/macro-path-uses-novel-syntax/5561. This PR makes the disambiguator *optional* instead of prohibited in contexts where it's not strictly required, so people can pass paths to macros in whatever form they consider natural (e.g. disambiguated form for value paths). This PR also accepts the disambiguator in paths with parenthesized arguments (`Fn::(Args)`) for consistency and to simplify testing of stuff like https://github.com/rust-lang/rust/pull/41856#issuecomment-301219194. Closes https://github.com/rust-lang/rust/issues/41740 cc @rust-lang/lang r? @nikomatsakis

Like #43008 (f668999), but _much more aggressive_.

2017-06-08Speed up expansion.Mark Simulacrum-17/+23
This reduces duplication, thereby increasing expansion speed.
2017-05-18Add an option to the parser to avoid parsing out of line modulesNick Cameron-2/+6
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.
2017-05-16Rollup merge of #41957 - llogiq:clippy-libsyntax, r=petrochenkovMark Simulacrum-28/+29
Fix some clippy warnings in libsyntax This is mostly removing stray ampersands, needless returns and lifetimes. Basically a lot of small changes.

2017-01-20Rollup merge of #39118 - jseyfried:token_tree_based_parser, r=nrcAlex Crichton-20/+4
Refactor the parser to consume token trees This is groundwork for efficiently parsing attribute proc macro invocations, bang macro invocations, and `TokenStream`-based attributes and fragment matchers. This improves parsing performance by 8-15% and expansion performance by 0-5% on a sampling of the compiler's crates. r? @nrc
