Bob Nystrom 49601e67c5 Don't require nonstandard __builtin_unreachable() in UNREACHABLE(). 
Fix #304 (I hope).
 2015-10-16 21:51:30 -07:00
Bob Nystrom 29eebe4928 Tweak libuv.py a bit. 2015-10-16 21:33:22 -07:00
Bob Nystrom 82d6453a7e Merge branch 'master' of https://github.com/ppearson/wren into ppearson-master 2015-10-16 21:24:22 -07:00
Bob Nystrom d431c2eaa8 Start sketching in support for reading from stdin. 2015-10-16 21:05:24 -07:00
Bob Nystrom c714c53c83 "Library" -> "module". 2015-10-15 19:38:25 -07:00
Bob Nystrom 3b09b35b59 Get rid of source path in module. 
It wasn't useful anyway since it always had the module name for all but
the main script.
 2015-10-15 18:17:42 -07:00
Bob Nystrom d5b9f0096c Move Meta to a separate module. 
Also cleaned up some of the code around loading the core module.
 2015-10-15 18:08:56 -07:00
Bob Nystrom 06a4e00f31 Store the module debug path in the ObjModule. 
Thanks, Michel!

Bob Nystrom 8980d34ee5 Only close an upvalue for a local if there actually is one for it. 2015-10-08 08:06:29 -07:00
Bob Nystrom 24cbb7f399 Fix closures in methods. 
A local name inside a method should always resolve to a self send even
if there is a local variable with that name outside of the method.

Bob Nystrom e968b4bf98 Fix two typos in the docs. 2015-10-03 21:45:59 -07:00
Bob Nystrom 76d188e018 Get rid of PrimitiveResult. 
Primitives still have a return value to indicate normal value returning
versus runtime errors or fiber switching since it minimizes branches
in the common case of a normal value result.
 2015-10-03 20:43:12 -07:00
Bob Nystrom 812bc15380 Get rid of the special "call" primitive result type. 
Instead, Fn.call(...) is a special *method* type that has the same
special sauce. The goal is eventually to get rid of the primitive
result type entirely.
 2015-10-03 19:04:11 -07:00
Bob Nystrom e41d9eac7c Tweak the embedding docs a bit. 2015-10-02 21:25:55 -07:00

Thanks, Michel!

Bob Nystrom b7ed774da3 Reading files! 
- File.close()
- File.open()
- File.read()
- file.readBytes()

And a few other little methods. Still lots more work to do, but it's a
start.
 2015-09-30 21:13:36 -07:00

Bob Nystrom 5129597c63 Unify PRIM_ERROR and PRIM_RUN_FIBER. 2015-09-30 07:32:39 -07:00
Bob Nystrom b05a74da19 Revamp how runtime errors and fiber switching is handled. 
- Add Fiber.transferError(_).
- Primitives place runtime errors directly in the fiber instead of on
  the stack.
- Primitives that change fibers set it directly in the VM.
- Allow a fiber's error to be any object (except null).
 2015-09-29 22:57:03 -07:00
Bob Nystrom 79354f5a97 Do some work on wrenCall(). 
- Add an explicit va_list version. That lets variadic functions
  forward to it.
- Fix a GC bug in wrenCall() with return values.
- Make the call API test not re-enter the VM.
 2015-09-29 19:29:10 -07:00
Bob Nystrom f757c9efac Better embedding API support (and tests!) for strings with null bytes. 
- Test that a foreign method can return strings.
- Test that a foreign method can return a string with null bytes.
- Test wrenCall().
- Allow passing NULL for "v" to wrenCall().
- Allow "a" for passing an explicit length byte array to wrenCall().

Bob Nystrom efceee4320 Let the host application control how System prints text. 2015-09-15 23:01:43 -07:00
Bob Nystrom 58e4d26648 "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
Bob Nystrom 66b89a493f Combine io.c and vm.c. 
(This is mainly to free up io.c as a built in module.)
 2015-09-13 22:29:47 -07:00

 2015-09-12 10:45:18 -07:00
Bob Nystrom 1a27593993 Error if a class tries to inherit from null. 
Fix #246.
 2015-09-12 10:14:04 -07:00
Bob Nystrom e1f979e78a Don't use string length in map benchmark (since it's slow now). 2015-09-12 09:59:30 -07:00
Bob Nystrom 92c2b2d5e0 Copy edit the string docs. 2015-09-12 09:42:31 -07:00
Bob Nystrom fe143644b3 Rationalize string lengths. 
The .count getter on string returns the number of code points. That's
O(n), but it's consistent with the rest of the main string API.

If you want the number of bytes, it's "string".bytes.count.

Updated the docs.

Fixes 68. Woo!
 2015-09-11 21:33:26 -07:00
Bob Nystrom c0b5ec9f15 Move codePointAt() to separate CodePointSequence class. 2015-09-11 07:56:01 -07:00
Bob Nystrom bda9ad880a Flesh out string byte handling a bit: 
- Get rid of public byteAt(_) method on strings. It's redundant and
  longer than .bytes[_].
- Implement bytes.count natively so it's O(1).
 2015-09-10 23:52:18 -07:00

Bob Nystrom 2b044666ee Reorganize trailing comma code a bit. 
- Split out syntax error tests.
- Avoid redundant handling of empty literals.
 2015-08-31 07:23:36 -07:00
Bob Nystrom 6559edbc56 Update docs to mention libuv. 2015-08-30 22:38:40 -07:00
Bob Nystrom 556af50f83 Revise low level fiber semantics to play nicer with schedulers. 
Now that I'm starting to write a real async scheduler on top of Wren's
basic fiber API, I have a better feel for what it needs. It turns out
run() is not it.

- Remove run() methods.
- Add transfer() which leaves the caller of the invoked fiber alone.
- Add suspend() to return control to the host application.
- Add Timer.schedule() to start a new independently scheduled fiber.
- Change Timer.sleep() so that it only transfers control to explicitly
  scheduled fibers, not any one.

Bob Nystrom b4deb30a02 Reorganize build scripts for libuv. 
- Create separate libs for each architecture. OS X doesn't need this
  (we just build a universal binary), but it will help Linux.
- Move the libuv build stuff into wren.mk where the actual dependency
  on the lib is.
- Download libuv to deps/ instead of build/. That way "make clean"
  doesn't blow it away.
- Don't redownload libuv unless needed.

Fixed some broken links in the readme
 2015-08-15 19:58:42 -07:00
Bob Nystrom 48bdbc7745 First pass at implementing foreign classes. 
Most of the pieces are there:

- You can declare a foreign class.
- It will call your C function to provide an allocator function.
- Whenever a foreign object is created, it calls the allocator.
- Foreign methods can access the foreign bytes of an object.
- Most of the runtime checking is in place for things like subclassing
  foreign classes.

There is still some loose ends to tie up:

- Finalizers are not called.
- Some of the error-handling could be better.
- The GC doesn't track how much memory a marked foreign object uses.

Bob Nystrom d4acbe8a70 A vertical slice of real libuv integration. 
This adds a "timer" module to the CLI that provides a Timer class with
a static sleep() method. Not the most exciting functionality in the
world, but it requires the full hunk of libuv integration:

- The CLI sets up libuv and runs the event loop.
- Added a new directory src/module for CLI modules.
- Updated all the make scripts to handle it.
- Reorganized some other CLI code.
