Added Sequence.count(predicate)
 2015-03-23 07:35:17 -07:00
Bob Nystrom 1301410142 Merge branch 'num_methods' of git://github.com/bjorn/wren into bjorn-num_methods 2015-03-21 12:54:08 -07:00
Thorbjørn Lindeijer 07951bbeae Added Num.pi and some tests 2015-03-19 21:12:50 +01:00
Thorbjørn Lindeijer 94804fe1a0 Added Sequence.count(predicate) 
Returns the number of elements in the sequence that pass the
`predicate`.

It could also have been implemented as:

  count(f) { reduce(0) {|a, b| f.call(b) ? a + 1 : a } }

But I considered the simple version more readable.

Also documented Sequence.count.

Bob Nystrom be11d09bd8 Store hash code in strings. 
Makes string equality and string map keys much faster.
Also did some other general string clean-up.

Thorbjørn Lindeijer d7a91117ac Reverse the argument order of List.insert 
The previous order, insert(element, index), was counter-intuitive.
I'm not aware of any list API that uses this order. I've checked:

* Ruby Array.insert(index, obj...)
* JavaScript array.splice(start, deleteCount[, item1[, item2[, ...]]])
* C++ / QList::insert(int i, const T & value)
* C++ / std::vector::insert
* Lua table.insert (list, [pos,] value)
* C# List<T>.Insert(int index, T item)
* Java Interface List<E>.add(int index, E element)
* Python list.insert(i, x)

So it seemed to me more like an oversight in Wren.

Bob Nystrom 64eccdd9be Reorganize tests and benchmark scripts. 
Mainly to get rid of one top level directory. But this will
also be useful when there are tests of the embedding API.
