2013-05-09Use a specialized string interner to reduce the need for owned stringsBjörn Steinbrink-22/+22
&str can be turned into @~str on demand, using to_owned(), so for strings, we can create a specialized interner that accepts &str for intern() and find() but stores and returns @~str.

before this change, the parser would parse 14.a() as a method call, but would parse 14.ø() as the floating-point number 14. followed by a function call. This is because it was checking is_alpha, rather than ident_start, and was therefore wrong with respect to unicode.

2013-04-08auto merge of #5787 : alexcrichton/rust/less-mut-fields, r=catamorphismbors-6/+4
This removes some of the easier instances of mutable fields where the explicit self can just become `&mut self` along with removing some unsafe blocks which aren't necessary any more now that purity is gone. Most of #4568 is done, except for [one case](https://github.com/alexcrichton/rust/blob/less-mut-fields/src/libcore/vec.rs#L1754) where it looks like it has to do with it being a `const` vector. Removing the unsafe block yields: ``` /Users/alex/code/rust2/src/libcore/vec.rs:1755:12: 1755:16 error: illegal borrow unless pure: creating immutable alias to const vec content /Users/alex/code/rust2/src/libcore/vec.rs:1755 for self.each |e| { ^~~~ /Users/alex/code/rust2/src/libcore/vec.rs:1757:8: 1757:9 note: impure due to access to impure function /Users/alex/code/rust2/src/libcore/vec.rs:1757 } ^ error: aborting due to previous error ``` I also didn't delve too much into removing mutable fields with `Cell` or `transmute` and friends.

2013-04-03auto merge of #5559 : jbclements/rust/change-to-tt-based-parsing, r=jbclementsbors-1/+6
Changes the parser to parse all streams into token-trees before hitting the parser proper, in preparation for hygiene. As an added bonus, it appears to speed up the parser (albeit by a totally imperceptible 1%). Also, many comments in the parser. Also, field renaming in token-trees (readme->forest, cur->stack).

Adds an assert_eq! macro that asserts that its two arguments are equal. Error messages can therefore be somewhat more informative than a simple assert, because the error message includes "expected" and "given" values.

2013-03-18librustc: Make the compiler ignore purity.Patrick Walton-2/+2
For bootstrapping purposes, this commit does not remove all uses of the keyword "pure" -- doing so would cause the compiler to no longer bootstrap due to some syntax extensions ("deriving" in particular). Instead, it makes the compiler ignore "pure". Post-snapshot, we can remove "pure" from the language. There are quite a few (~100) borrow check errors that were essentially all the result of mutable fields or partial borrows of `@mut`. Per discussions with Niko I think we want to allow partial borrows of `@mut` but detect obvious footguns. We should also improve the error message when `@mut` is erroneously reborrowed.

r? It looks to me like the string_reader and tt_reader structs are GC pointers only because they predate the modern borrow system. This commit leaves the type names string_reader and tt_reader alone (they still refer to GC-ed pointers), but internally the functions now use borrowed pointers to refer to these structures. My guess would be that it's possible to move this change outward and not use the GCed pointers at all, but that change looks like it could be a larger one. Actually, I'm delighted at how quick this change was.

2013-02-03Converted libcore/uint-template.rs to the new string functions.Marvin Löbel-2/+2
- Moved ToStr implementation of unsigned integers to uint-template.rs. - Marked the `str()` function as deprecated. - Forwarded all conversion functions to `core::num::to_str_common()` and `core::num::from_str_common()`. - Fixed most places in the codebase where `to_str()` is being used. - Added uint-template to_str and from_str overflow tests.

2013-01-29libstd: Remove "dual impls" from the language and enforce coherence rules. ↵Patrick Walton-1/+1
r=brson "Dual impls" are impls that are both type implementations and trait implementations. They can lead to ambiguity and so this patch removes them from the language. This also enforces coherence rules. Without this patch, records can implement traits not defined in the current crate. This patch fixes this, and updates all of rustc to adhere to the new enforcement. Most of this patch is fixing rustc to obey the coherence rules, which involves converting a bunch of records to structs.
