fcf4197139 Add Object.same(_,_) to access built-in equality even for classes that may override ==. 
Had to add a new metaclass for Object since it now has its own static method so we
can't just use Class as its metaclass. (We don't want *every* class to have a same(_,_)
static method.)

82ce1d8be9 Fix up Meta.eval(_). 
- Made it use primitives instead of foreign functions.
- This fixed an issue where the interpreter loop was running re-entrantly.
- Which in turn fixed a GC bug.
- Report a runtime error if the argument isn't a string.
- Report a runtime error if the source doesn't compile.

a8ea2a91a6 Use deferred execution for Sequence.map and Sequence.where 
The methods Sequence.map and Sequence.where are now implemented using
deferred execution. They return an instance of a new Sequence-derived
class that performs the operation while iterating. This has three main
advantages:

* It can be computationally cheaper when not the whole sequence is
  iterated.

* It consumes less memory since it does not store the result in a newly
  allocated list.

* They can work on infinite sequences.

Some disadvantages are:

* Iterating the returned iterator will be slightly slower due to
  the added indirection.

* You should be aware that modifications made to the original sequence
  will affect the returned sequence.

* If you need the result in a list, you now need to call Sequence.list
  on the result.

c00d6ad694 Added Sequence.each 
This is a bit of a style preference since of course you can always write
the same thing with a for loop. However, I think sometimes the code
looks better when using this method.

It also provides an alternative to Sequence.map for cases where you
don't need the resulting list, and one that becomes especially necessary
when Sequence.map is changed to return a new sequence. The example in
the README.md file was using Sequence.map in a way that required this
alternative in that case.

07f9d4d2be Tweak Sequence.all() and Sequence.any(). 
When possible, they return the actual value from the predicate
instead of always just "true" and "false". This matches && and ||
which evaluate to the RHS or LHS when appropriate.

72c38a59ce 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.

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.

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.

bb647d4247 Start getting module loading working. 
Right now, it uses a weird "import_" method on String which
should either be replaced or at least hidden behind some syntax.

But it does roughly the right thing. Still lots of corner cases to
clean up and stuff to fix. In particular:

- Need to handle compilation errors in imported modules.
- Need to implicitly import all core and IO types into imported module.
- Need to handle circular imports.
  (Just need to give entry module the right name for this to work.)

bcf052436f Merge pull request #94 from edsrzf/fix-neg-number 
Don't treat negative numbers as literals
 2015-01-09 07:00:12 -08:00
Evan Shaw
75d28c083c Don't treat negative numbers as literals 
Fixes #93.

Previously, "1 -1" was lexed as two number tokens: a positive literal and
a negative literal. This caused problems when it came to parsing.

Now the '-' and the second number are separate tokens.

Note this is a breaking change, since `-16.sqrt` is now parsed as `-(16.sqrt)`,
as opposed to `(-16).sqrt`.

There is a small bit of overhead to doing it this way, but it might be possible
to optimize that out in the compiler at some point in the future.

This lets us make it a grammar feature and not a lexer trick.

an operator, but not when used as a parameter delimiter in a block
argument.

a550d6cea4 Change how new operators are compiled. 
Instead of an instruction that always instantiates an instance,
the "new" is compiled to a method call on the class, followed by a
method call on the (presumably) new instance.

The former lets built-in types like Fn do special stuff instead of
allocating an instance. In particular, it means:

  new Fn { ... }

can just return the block argument.

- Arithmetic operators error if the operand is not a number.
- Real error for method not found.
- Associate source file name, and method names with functions.
- Debug line number info for functions.

Unfortunately, this regresses perf on fib about 15%, mostly
because of the better checking in arithmetic ops.

There's still a bunch of clean up to do, but this is a big step
in the right direction.

507e89d3b3 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:

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

Since Wren needs to do a super call to get to the parent _count,
the other languages do now too.
