breaking change to std.io API * Merge io.InStream and io.OutStream into io.File * Introduce io.OutStream and io.InStream interfaces - io.File implements both of these * Move mem.IncrementingAllocator to heap.IncrementingAllocator Instead of: ``` %return std.io.stderr.printf("hello\n"); ``` now do: ``` std.debug.warn("hello\n"); ``` To print to stdout, see `io.getStdOut()`. * Rename std.ArrayList.resizeDown to std.ArrayList.shrink. 2017-10-31 16:47:55 +08:00			`const std = @import("std");`

std.io.getStdOut and related fns no longer can error Thanks to the Windows Process Environment Block, it is possible to obtain handles to the standard input, output, and error streams without possibility of failure. 2019-11-13 09:36:07 +08:00			`const stdout_file = std.io.getStdOut();`

replace `%return` with `try` See #632 better fits the convention of using keywords for control flow 2018-01-08 05:51:46 +08:00			`try stdout_file.write("Hello, world!\n");`
input output 2015-08-06 06:46:40 +08:00			`}`
