Flesh out string byte handling a bit: - Get rid of public byteAt(_) method on strings. It's redundant and longer than .bytes[_]. - Implement bytes.count natively so it's O(1). 2015-09-10 23:52:18 -07:00			`var bytes = "\x00\x12\x34\x56\x78\xab\xCD\xfFf".bytes`
More stuff for working with strings and bytes! - "\x" escape sequence to put byte values in strings: "\x34" - String.byteAt(index) gets value of byte in string. - String.bytes returns a raw sequence of bytes for a string. - String.codePointAt(index) gets the code point at an offset as a raw number. 2015-03-27 20:44:07 -07:00
"IO" -> "System". Get rid of the separate opt-in IO class and replace it with a core System class. - Remove wren_io.c, wren_io.h, and io.wren. - Remove the flags that disable it. - Remove the overloads for print() with different arity. (It was an experiment, but I don't think it's that useful.) - Remove IO.read(). That will reappear using libuv in the CLI at some point. - Remove IO.time. Doesn't seem to have been used. - Update all of the tests, docs, etc. I'm sorry for all the breakage this causes, but I think "System" is a better name for this class (it makes it natural to add things like "System.gc()") and frees up "IO" for referring to the CLI's IO module. 2015-09-15 07:46:09 -07:00			`System.print(bytes[0]) // expect: 0`
