Bob Nystrom 46c1ba9249 Fix #2. Finish implementing Range. 
Covers error and edge cases and fully tested now.
 2014-01-20 13:20:22 -08:00
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.
 2014-01-20 08:45:15 -08:00
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.

Bob Nystrom f3a1f7e677 Fibers! 
Still have some edge cases to implement but the basics are in
place and working now.
 2014-01-12 11:02:07 -08:00

Bob Nystrom e64d8ace9a Ensure upvalue value is initialized. 
Avoids a crash if a GC happens before the upvalue is closed.
 2014-01-07 23:03:15 -08:00
Bob Nystrom 3be059a137 Fix scoping and break statements. 
Variables declared in the loop were not properly disposed of
when you broke out of the loop.
 2014-01-06 08:01:04 -08:00
Bob Nystrom 90a769b6d1 Correctly terminate debug function name. 2014-01-06 07:54:00 -08:00
Bob Nystrom 46e1e7f069 Make string buffer for converting number to string large enough. 2014-01-06 07:53:41 -08:00
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.
 2014-01-04 11:08:31 -08:00
Bob Nystrom f82a034b57 Add time to GC tracing. 2014-01-03 13:17:14 -08:00

Bob Nystrom e46b4b30b9 Make Buffer "generic". 
This lets us make a growable line-number buffer.
 2014-01-01 22:23:03 -08:00
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.
 2014-01-01 13:31:19 -08:00
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.
 2014-01-01 13:25:24 -08:00
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.
 2013-12-30 07:30:50 -08:00
Bob Nystrom c8fe27d6c4 Allow empty blocks. 2013-12-29 10:46:21 -08:00
Bob Nystrom a9323376ec "native" -> "foreign". 2013-12-29 10:14:38 -08:00
Bob Nystrom 63d1255566 Start sketching in the FFI. 2013-12-29 10:06:35 -08:00
Bob Nystrom 667d393fbb Write a bunch of docs. 2013-12-28 09:37:41 -08:00
Bob Nystrom afdcafcecb Remove explicit calls to free() and malloc(). 2013-12-27 09:07:35 -08:00
Bob Nystrom a8c725ea3f Use growable buffers for bytecode and strings. 
Ensures the compiler can handle long chunks of code and strings.
 2013-12-27 07:22:43 -08:00
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.
 2013-12-26 16:58:03 -08:00
Bob Nystrom 350c0194b6 "unsigned char" -> "uint8_t". 2013-12-25 16:31:30 -08:00
Bob Nystrom e62bccd7f2 Inline the bytecode array in ObjFn. 2013-12-25 16:19:35 -08:00
Bob Nystrom 8c4a58a0a3 Make CallFrame and Method use Obj* for functions. 
There's no point in packing it in a Value since it will always
be an ObjFn or ObjClosure. Leaving it an Obj* is a bit faster.

Also fixed a bug where it was freeing the closure's flexible
array of upvalues.
 2013-12-25 16:12:07 -08:00
Bob Nystrom ba0f39a5e0 Tweak README. 2013-12-25 15:03:17 -08:00
Bob Nystrom 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:

    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
Bob Nystrom 2b65e47747 Use getNumArguments() in method bind. 2013-12-24 22:10:30 -08:00
