Made the fib benchmark a bit faster This way fib.wren was consistently about 6% faster for me. 2015-02-28 21:14:28 +01:00			`class Fib {`

			`if (n < 2) return n`
			`return get(n - 1) + get(n - 2)`

Add trivial fib benchmark. 2013-11-14 20:57:56 -08:00			`}`

"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			`var start = System.clock`
Range operators! Added ".." and "..." infix operators. Num implements them to return Range objects. Those in turn implement the iterator protocol, so now numeric for loops are easy: for (i in 1..10) { ... } I also cleaned up the Wren benchmarks to use this. In the process, I discovered the method_call benchmark really just showed loop peformance, so I unrolled the loops in all of the languages to stress method calls. 2013-12-25 15:01:45 -08:00			`for (i in 1..5) {`

Get a basic benchmark runner going. 2013-11-22 08:55:22 -08:00			`}`
Simple string interpolation. This allows "%(...)" inside a string literal to interpolate the stringified result of an expression. It doesn't support custom interpolators or format strings, but we can consider extending that later. 2015-11-11 07:55:48 -08:00			`System.print("elapsed: %(System.clock - start)")`
