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 01:47:55 -07:00			`const std = @import("std");`

std.io: introduce buffered I/O and change API I started working on #465 and made some corresponding std.io API changes. New structs: * std.io.FileInStream * std.io.FileOutStream * std.io.BufferedOutStream * std.io.BufferedInStream Removed: * std.io.File.in_stream * std.io.File.out_stream Now instead of &file.out_stream or &file.in_stream to get access to the stream API for a file, you get it like this: var file_in_stream = io.FileInStream.init(&file); const in_stream = &file_in_stream.stream; var file_out_stream = io.FileOutStream.init(&file); const out_stream = &file_out_stream.stream; This is evidence that we might not need any OOP features - See #130. 2017-11-07 00:22:27 -08:00			`%return stdout_file.write("Hello, world!\n");`
