Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 12:18:55 +00:00			`//@ run-pass`
Add `#![allow(..)]` as necessary to get re-migrated run-pass tests compiling with clean stderr again. Most were added mechanically. 2018-09-25 21:51:35 +00:00			`#![allow(unused_must_use)]`
rustdoc: Replace no-pretty-expanded with pretty-expanded Now that features must be declared expanded source often does not compile. This adds 'pretty-expanded' to a bunch of test cases that still work. 2015-03-22 20:13:15 +00:00			`//@ pretty-expanded FIXME #23616`

std: Implement stdio for `std::io` This is an implementation of RFC 899 and adds stdio functionality to the new `std::io` module. Details of the API can be found on the RFC, but from a high level: * `io::{stdin, stdout, stderr}` constructors are now available. There are also `_raw` variants for unbuffered and unlocked access. All handles are globally shared (excluding raw variants). * The stderr handle is no longer buffered. * All handles can be explicitly locked (excluding the raw variants). The `print!` and `println!` machinery has not yet been hooked up to these streams just yet. The `std::fmt::output` module has also not yet been implemented as part of this commit. 2015-02-25 07:27:20 +00:00			`use std::io;`
librustc: Stop reexporting the standard modules from prelude. 2013-05-25 02:35:29 +00:00
Fix run-pass tests to have 'pub fn main' This is required by the check-fast target because each test is slurped up into a submodule. 2013-09-25 07:43:37 +00:00			`pub fn main() {`
Update run-pass test suite to use dyn 2019-05-28 18:47:21 +00:00			`let stdout = &mut io::stdout() as &mut dyn io::Write;`
Deprecate the bytes!() macro. Replace its usage with byte string literals, except in `bytes!()` tests. Also add a new snapshot, to be able to use the new b"foo" syntax. The src/etc/2014-06-rewrite-bytes-macros.py script automatically rewrites `bytes!()` invocations into byte string literals. Pass it filenames as arguments to generate a diff that you can inspect, or `--apply` followed by filenames to apply the changes in place. Diffs can be piped into `tip` or `pygmentize -l diff` for coloring. 2014-06-18 18:25:36 +00:00			`stdout.write(b"Hello!");`
