Bob Nystrom 97bf314f4b Make Range a native object type. 
Still need to implement better semantics, but this is an 
important first step. It's much faster now too, which is good.

Bob Nystrom d40d04f0c5 Include numeric loop in for benchmark. 2014-01-20 08:43:10 -08:00
Bob Nystrom 83b5968340 Get static methods fully working. 
They are compiled as local variables defined in an implicit
scope surrounding the class. This has the right semantics and,
better, means that there's no VM support needed for them.

They're purely syntax sugar.

Bob Nystrom e8791b6bab Don't inherit metaclasses. 
Also disallow super() in static methods. It won't do anything
useful (it always just delegates to Class) anyway.

Still have some edge cases to implement but the basics are in
place and working now.

Bob Nystrom e64d8ace9a Ensure upvalue value is initialized. 
Avoids a crash if a GC happens before the upvalue is closed.

Variables declared in the loop were not properly disposed of
when you broke out of the loop.

Bob Nystrom b979272305 Clean up text handling a bit: 
- Rename IO.write -> IO.print.
- Make IO.write not print a newline.
- Support \u Unicode escapes in strings.
 2014-01-05 12:27:12 -08:00
Bob Nystrom 870f3b8b93 Allow more than 256 methods and constants. 
Class symbol tables now grow on demand, and the relevant
instructions take 16-bit arguments. There's a small perf hit
for this, but only a few percent, which is good.

Bob Nystrom e46b4b30b9 Make Buffer "generic". 
This lets us make a growable line-number buffer.

Bob Nystrom a6fd0b2dd2 Move SymbolTable to wren_utils. 2014-01-01 20:57:58 -08:00
Bob Nystrom b750ece08b Move object freeing over to wren_value. 
That's where allocation is, so it makes sense.

Bob Nystrom 48db3a9620 Start adding support for runtime errors: 
- Primitives can now signal an error.
- An error prints a callstack and ends the current (and right 
  now only) fiber.
- 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.

Bob Nystrom 45456733aa Fix a few GC bugs. 
Adding a to a symbol table can trigger a GC, so we need to make
sure we don't do that while sitting on an unpinned object.

Bob Nystrom a8c725ea3f Use growable buffers for bytecode and strings. 
Ensures the compiler can handle long chunks of code and strings.

Bob Nystrom 3506a39e27 Pass in all data when creating function. 2013-12-26 17:28:33 -08:00
Bob Nystrom 24686eb4be First step towards making FnObjs smarter about size. 
Currently, they have a hardcoded number of constants and 
bytecodes. That wastes memory in most cases and fails 
catastrophically when there is too much bytecode.

To fix this, we should use growable buffers for both during
compilation and then only create the FnObj when done compiling.

This moves a bunch of stuff around and gets it to the point
where functions are created at the end of compilation. It
doesn't yet size functions appropriately, but all tests are
passing, so this is a good checkpoint.
