2017-08-13Rollup merge of #43782 - nrc:include, r=GuillaumeGomezGuillaume Gomez-5/+6
Fix include! in doc tests By making the path relative to the current file. Fixes #43153 [breaking-change] - if you use `include!` inside a doc test, you'll need to change the path to be relative to the current file rather than relative to the working directory.

2016-10-14Avoid many CrateConfig clones.Nicholas Nethercote-1/+1
This commit changes `ExtCtx::cfg()` so it returns a `CrateConfig` reference instead of a clone. As a result, it also changes all of the `cfg()` callsites to explicitly clone... except one, because the commit also changes `macro_parser::parse()` to take `&CrateConfig`. This is good, because that function can be hot, and `CrateConfig` is expensive to clone. This change almost halves the number of heap allocations done by rustc for `html5ever` in rustc-benchmarks suite, which makes compilation 1.20x faster.

2016-06-27Auto merge of #34424 - jseyfried:breaking_batch, r=Manishearthbors-11/+11
Batch up libsyntax breaking changes Batch of the following syntax-[breaking-change] changes: - #34213: Add a variant `Macro` to `TraitItemKind` - #34368: Merge the variant `QPath` of `PatKind` into the variant `PatKind::Path` - #34385: Move `syntax::ast::TokenTree` into a new module `syntax::tokenstream` - #33943: - Remove the type parameter from `visit::Visitor` - Remove `attr::WithAttrs` -- use `attr::HasAttrs` instead. - Change `fold_tt`/`fold_tts` to take token trees by value and avoid wrapping token trees in `Rc`. - Remove the field `ctxt` of `ast::Mac_` - Remove inherent method `attrs()` of types -- use the method `attrs` of `HasAttrs` instead. - #34316: - Remove `ast::Decl`/`ast::DeclKind` and add variants `Local` and `Item` to `StmtKind`. - Move the node id for statements from the `StmtKind` variants to a field of `Stmt` (making `Stmt` a struct instead of an alias for `Spanned<StmtKind>`) - Rename `ast::ExprKind::Again` to `Continue`. - #34339: Generalize and abstract `ThinAttributes` to `ThinVec<Attribute>` - Use `.into()` in convert between `Vec<Attribute>` and `ThinVec<Attribute>` - Use autoderef instead of `.as_attr_slice()` - #34436: Remove the optional expression from `ast::Block` and instead use a `StmtKind::Expr` at the end of the statement list. - #34403: Move errors into a separate crate (unlikely to cause breakage)
2016-06-26Rollup merge of #34385 - cgswords:tstream, r=nrcJeffrey Seyfried-8/+9
syntax-[breaking-change] cc #31645 (Only breaking because ast::TokenTree is now tokenstream::TokenTree.) This pull request refactors TokenTrees into their own file as src/libsyntax/tokenstream.rs, moving them out of src/libsyntax/ast.rs, in order to prepare for an accompanying TokenStream implementation (per RFC 1566).

2016-06-16Add an abs_path member to FileMap, use it when writing debug info.Ted Mielczarek-2/+2
When items are inlined from extern crates, the filename in the debug info is taken from the FileMap that's serialized in the rlib metadata. Currently this is just FileMap.name, which is whatever path is passed to rustc. Since libcore and libstd are built by invoking rustc with relative paths, they wind up with relative paths in the rlib, and when linked into a binary the debug info uses relative paths for the names, but since the compilation directory for the final binary, tools trying to read source filenames will wind up with bad paths. We noticed this in Firefox with source filenames from libcore/libstd having bad paths. This change stores an absolute path in FileMap.abs_path, and uses that if available for writing debug info. This is not going to magically make debuggers able to find the source, but it will at least provide sensible paths.

2015-06-16Fix file!(), line!() and column!() macrosSimonas Kazlauskas-3/+3
These used to return wrong results in case they were expanded inside compiler’s iternal syntax sugar (closures, if-let) expansions Fixes #26322
2015-04-21syntax: remove #![feature(box_syntax, box_patterns)]Erick Tryzelaar-1/+1
2015-04-14include_bytes! now registers the file includedTheo Belaire-0/+5
This is a little bit tricky, since with include_str!, we know that we are including utf-8 content, so it's safe to store the source as a String in a FileMap. We don't know that for include_bytes!, but I don't think we actually need to track the contents anyways, so I'm passing "". new_filemap does check for the zero length content, and it should be reasonable, howeven I'm not sure if it would be better to pass None instead of Some(Rc::new("")) as the src component of a FileMap. Fixes bug #24348
2015-04-05Work towards a non-panicing parser (libsyntax)Phil Dawes-2/+2
- Functions in parser.rs return PResult<> rather than panicing - Other functions in libsyntax call panic! explicitly for now if they rely on panicing behaviour. - 'panictry!' macro added as scaffolding while converting panicing functions. (This does the same as 'unwrap()' but is easier to grep for and turn into try!()) - Leaves panicing wrappers for the following functions so that the quote_* macros behave the same: - parse_expr, parse_item, parse_pat, parse_arm, parse_ty, parse_stmt
2015-03-23Add generic conversion traitsAaron Turon-1/+1
This commit: * Introduces `std::convert`, providing an implementation of RFC 529. * Deprecates the `AsPath`, `AsOsStr`, and `IntoBytes` traits, all in favor of the corresponding generic conversion traits. Consequently, various IO APIs now take `AsRef<Path>` rather than `AsPath`, and so on. Since the types provided by `std` implement both traits, this should cause relatively little breakage. * Deprecates many `from_foo` constructors in favor of `from`. * Changes `PathBuf::new` to take no argument (creating an empty buffer, as per convention). The previous behavior is now available as `PathBuf::from`. * De-stabilizes `IntoCow`. It's not clear whether we need this separate trait. Closes #22751 Closes #14433 [breaking-change]
2015-03-13syntax: use lookahead to distinguish inner and outer attributes, instead of ↵Eduard Burtescu-1/+1
passing the latter around.
2015-03-12Stabilize std::pathAaron Turon-5/+1
This commit stabilizes essentially all of the new `std::path` API. The API itself is changed in a couple of ways (which brings it in closer alignment with the RFC): * `.` components are now normalized away, unless they appear at the start of a path. This in turn effects the semantics of e.g. asking for the file name of `foo/` or `foo/.`, both of which yield `Some("foo")` now. This semantics is what the original RFC specified, and is also desirable given early experience rolling out the new API. * The `parent` function now succeeds if, and only if, the path has at least one non-root/prefix component. This change affects `pop` as well. * The `Prefix` component now involves a separate `PrefixComponent` struct, to better allow for keeping both parsed and unparsed prefix data. In addition, the `old_path` module is now deprecated. Closes #23264 [breaking-change]
2015-03-04std: Deprecate std::old_io::fsAlex Crichton-13/+20
This commit deprecates the majority of std::old_io::fs in favor of std::fs and its new functionality. Some functions remain non-deprecated but are now behind a feature gate called `old_fs`. These functions will be deprecated once suitable replacements have been implemented. The compiler has been migrated to new `std::fs` and `std::path` APIs where appropriate as part of this change.
2015-02-27Replace MacExpr / MacPat / MacItems with MacEagerKeegan McAllister-7/+7
MacEager is a MacResult implementation for the common case where you've already built each form of AST that you might return. Fixes #17637. Based on #18814. This is a [breaking-change] for syntax extensions: * MacExpr::new becomes MacEager::expr. * MacPat::new becomes MacEager::pat. * MacItems::new becomes MacEager::items. It takes a SmallVector directly, not an iterator.
