Will Speak d45c0d7f82 Add Support for \U Style Unicode Escapes 
This allows fuky things such as 🚀 and 😀 to be Direclty encoded in
Wren strings.

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!
 2015-10-14 07:37:13 -07:00
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.
 2015-10-05 07:44:51 -07:00
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
Bob Nystrom d61d7fd5b4 Don't pass fiber explicitly to primitives. 
Thanks, Michel!
 2015-10-02 07:51:12 -07:00
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 bacbd85543 Add .isInfinity and .isInteger to Num. 2015-09-30 08:41:43 -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().

Peter Pearson 52b1b7698f Modified libuv.py file to be able to work with Python 2.6 2015-09-24 21:05:08 +12:00
Bob Nystrom a944ead5b4 Give the docs some love. 2015-09-22 21:19:38 -07:00
Bob Nystrom 505b48fdac Add a real Pygments lexer for Wren (finally!). 2015-09-22 07:59:54 -07:00
Bob Nystrom 36f7d74183 Unify "script" and "project" under "util". 2015-09-22 07:45:58 -07:00
Bob Nystrom 2f9ba2beaa Merge branch 'buildfix' of https://github.com/krypt-n/wren into krypt-n-buildfix 2015-09-21 19:48:08 -07:00
Bob Nystrom f6083b1756 Simplify how built-in foreign methods and classes are wired up. 2015-09-21 07:58:39 -07:00
krypt-n 9c92d90374 Use python2 executable for libuv buildscripts 
Fixes build for systems with python == python3, as long as a python2
executable exists
 2015-09-20 00:49:29 +02:00
Bob Nystrom 8ef4ea6186 Allow super calls in static methods. 2015-09-19 15:19:41 -07:00
Bob Nystrom 19f70b4035 Simplify and optimize how keywords are lexed. 2015-09-17 20:51:24 -07:00
Bob Nystrom dc527c8d86 Add "io" module with beginnings of a File class. 2015-09-16 07:34:49 -07:00
Bob Nystrom 251752fcfb Make join() require parentheses without a separator. 2015-09-16 07:15:48 -07:00
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
Bob Nystrom ea5c3b01eb Add module for Scheduler. 
Also reorganizes some code to make it easier to add more modules.
 2015-09-13 11:32:39 -07:00
Bob Nystrom f36a795534 Automatically update the string constants when a builtin module changes. 2015-09-13 10:03:02 -07:00
Bob Nystrom e1cf8e22c3 Merge pull request #300 from jesskay/patch-1 
Correct platform.system() call
 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 adcb5bccba Simplify emitConstant(). 
Thanks, Michel!
 2015-09-09 06:44:26 -07:00
Bob Nystrom 1df7565bb9 Fix bug in passing a range as the string subscript. 2015-09-08 20:59:47 -07:00
Jess Kay 6330aae20c Correct platform.system() call 
An "arch" somehow ended up in the platform.system() call, which takes no arguments.
 2015-09-06 02:11:08 +01:00
Bob Nystrom 783a5b750a Get ranges working in string subscripts (again). 
Now with UTF-8 hotness!
 2015-09-01 22:14:55 -07:00
Bob Nystrom 2e83f056c1 No more default constructors. 
Fixes #296.
