bors f8c9aec344 auto merge of #14400 : kballard/rust/lexer_crlf_handling, r=cmr The lexer already ignores CRLF in between tokens, but it doesn't properly handle carriage returns inside strings and doc comments. Teach it to treat CRLF as LF inside these tokens, and to disallow carriage returns that are not followed by linefeeds. This includes handling an escaped CRLF inside a regular string token the same way it handles an escaped LF. This is technically a breaking change, as bare carriage returns are no longer allowed, and CRLF sequences are now treated as LF inside strings and doc comments, but it's very unlikely to actually affect any real-world code. This change is necessary to have Rust code compile on Windows the same way it does on Unix. The mozilla/rust repository explicitly sets eol=lf for Rust source files, but other Rust repositories don't. Notably, rust-http cannot be compiled on Windows without converting the CRLF line endings back to LF. [breaking-change]		2014-06-19 05:21:16 +00:00

The Rust Programming Language

This is a compiler for Rust, including standard libraries, tools and documentation.

Quick Start

Download a binary installer for your platform.
Read the tutorial.
Enjoy!

Note: Windows users can read the detailed getting started notes on the wiki.

Building from Source

Make sure you have installed the dependencies:
- g++ 4.7 or clang++ 3.x
- python 2.6 or later (but not 3.x)
- perl 5.0 or later
- GNU make 3.81 or later
- curl
- git
Download and build Rust:

You can either download a tarball or build directly from the repo.

To build from the tarball do:
```
 $ curl -O http://static.rust-lang.org/dist/rust-nightly.tar.gz
 $ tar -xzf rust-nightly.tar.gz
 $ cd rust-nightly
```
Or to build from the repo do:
```
 $ git clone https://github.com/rust-lang/rust.git
 $ cd rust
```
Now that you have Rust's source code, you can configure and build it:
```
 $ ./configure
 $ make && make install
```
Note: You may need to use sudo make install if you do not normally have permission to modify the destination directory. The install locations can be adjusted by passing a --prefix argument to configure. Various other options are also supported, pass --help for more information on them.

When complete, make install will place several programs into /usr/local/bin: rustc, the Rust compiler, and rustdoc, the API-documentation tool. system.
Read the tutorial.
Enjoy!

Notes

Since the Rust compiler is written in Rust, it must be built by a precompiled "snapshot" version of itself (made in an earlier state of development). As such, source builds require a connection to the Internet, to fetch snapshots, and an OS that can execute the available snapshot binaries.

Snapshot binaries are currently built and tested on several platforms:

Windows (7, 8, Server 2008 R2), x86 only
Linux (2.6.18 or later, various distributions), x86 and x86-64
OSX 10.7 (Lion) or greater, x86 and x86-64

You may find that other platforms work, but these are our officially supported build environments that are most likely to work.

Rust currently needs about 1.5 GiB of RAM to build without swapping; if it hits swap, it will take a very long time to build.

There is a lot more documentation in the wiki.
