Bob Nystrom 4ad4953196 Fix typo. 
Thanks, Michel!
 2015-12-26 20:12:35 -08:00
Bob Nystrom 8ab329ff91 Make wren.mk log wren_to_c_string. 
Thanks, Michel!
 2015-12-26 20:11:48 -08:00
Bob Nystrom 8203baf7bd Initialize match in the test script. 
Thanks, Michel!
 2015-12-26 20:08:20 -08:00
Bob Nystrom 0ac793d4f8 Add Directory.list() to io. 2015-12-24 10:12:12 -08:00
Bob Nystrom 1ebc711c30 Allow call and unary expressions as map keys. 2015-12-22 16:00:50 -08:00
Bob Nystrom 55beda3ea9 Simplify the foreign call preamble a bit. 
We don't need to store the number of arguments since we can calculate
it from the start and top of the stack.
 2015-12-15 17:10:02 -08:00
Bob Nystrom 01e8f9053e Add a benchmark to test the Wren C API. 
I've got some ideas on how to tweak the embedding API, but I want to
see what performance impact they have first, so this adds a little
benchmark that just calls a foreign method a ton of times.
 2015-12-15 16:02:13 -08:00
Bob Nystrom 873926915f Don't allow fibers as map keys. 
I hacked in support for it for a misguided reason (trying to fake
"thread-local storage") and ended up not using it for that anyway.
 2015-12-15 10:42:21 -08:00
Bob Nystrom 8d9feb4bc9 Fix typo in benchmark. 2015-12-15 10:37:53 -08:00
Bob Nystrom bcc40ab66a Clean up a few little things: 
- Fix the instruction output when debug dumping code.
- Don't pass around the classCompiler since Compiler stores it.
 2015-12-14 17:10:10 -08:00
Bob Nystrom e7d10218db Grow the stack as needed. 
This is untuned for performance, but seems to be doing the right thing.
 2015-12-14 08:00:22 -08:00
Bob Nystrom c7cd1fb1ac Track the maximum number of slots each function may use. 
This is the first step towards dynamically grown stacks. We don't want
to check for stack overflow on every single push, so we store the max
number of slots a function might need and (in later patches) ensure
at function call time that that many slots are available.
 2015-12-13 22:57:40 -08:00
Bob Nystrom 2df5362ab2 Handle compile errors in imported modules. 2015-12-08 07:49:37 -08:00

Bob Nystrom c46507d937 Fix .gitignore (and add incorrectly ignored file!) 2015-11-27 11:22:09 -08:00
Bob Nystrom 5454152dff Merge pull request #313 from acook/patch-1 
Fixing a couple of typos in the classes docs.
 2015-11-25 08:59:16 -08:00
Bob Nystrom 69a5c1d017 Avoid empty array initializer which seems to be problematic on VC++. 2015-11-25 08:36:42 -08:00
Bob Nystrom 5bde04db4c Eagerly evaluate interpolated expressions. 
If we ever support custom string templates, we'll need to go back to
compiling them to functions. But, for now, they can be evaluated
eagerly, leading to simpler code.
 2015-11-23 07:08:14 -08:00
Bob Nystrom fb72e0fff7 Document method scope. 2015-11-21 14:00:21 -08:00
Bob Nystrom 03163a760f Document interpolation. 2015-11-21 09:20:50 -08:00
Bob Nystrom 78655c68b0 Simple string interpolation. 
This allows "%(...)" inside a string literal to interpolate the
stringified result of an expression.

It doesn't support custom interpolators or format strings, but we can
consider extending that later.
 2015-11-11 07:55:48 -08:00
Bob Nystrom 71575d9179 Switch to O3 for release builds. 
It now seems to be fairly consistently faster on my machine:

binary_trees - wren     0.22s 0.0023 100.10% relative to baseline
binary_trees_gc - wren  0.85s 0.0160 112.63% relative to baseline

 2015-11-10 07:33:15 -08:00
Bob Nystrom aaab14959f Get rid of extraneous "," in module macros. 
Thanks, Michel!
 2015-11-10 07:13:19 -08:00
Bob Nystrom de7b062a03 Tweak module docs a bit. 2015-11-09 07:42:48 -08:00

Bob Nystrom 82706b74fc Reorganize site to make room for documenting the other built-in modules. 2015-11-08 13:31:22 -08:00
Bob Nystrom 8c0dae1320 Move precedence table to syntax page. 2015-11-08 10:59:23 -08:00
Bob Nystrom 0bf5dc42ef Remove outdated docs. 2015-11-07 13:00:49 -08:00
Bob Nystrom 7ae9888c4f It turns out "is" is just a normal overridable operator. Who knew? 2015-11-07 13:00:24 -08:00
Bob Nystrom 931d9ca4d3 Reorganize the language guide. 
- Rename "Expressions" -> "Method Calls".
- Organize "Types" and "Language" into a single linear narrative.
- Mobile-specific navigation to handle the longer guide.
- Rename "Fibers" -> "Concurrency".
- Get rid of duplicate stuff about signatures in "Classes".
- Add next/prev links to each page in the guide.
- Move "Contributing" and "Community" up to the top level.
- Move the precendence table to a separate "Grammar" page.
- Lots of other little stuff.
 2015-11-07 11:09:04 -08:00
Bob Nystrom bbd6b827b5 Fix C++ compile errors. 2015-11-04 07:07:33 -08:00
Bob Nystrom 2ff8acbe1a Tweak a few things in the new GC. 
- Make sure it handles an empty gray set.
- Make sure growing the gray stack doesn't itself trigger a GC.
- Make sure it works when stress testing is enabled.
- Ensure the tests kick off a GC.
 2015-10-29 07:38:09 -07:00
Bob Nystrom 25bd182c58 Fix some typos and rename some functions. 
Makes the tri-color abstraction more explicit throughout the code.
 2015-10-28 07:55:04 -07:00
Bob Nystrom e3c9324dd9 Merge branch 'master' into iwillspeak-iterative-gc 2015-10-28 07:46:06 -07:00
Bob Nystrom e985e6fe07 Make sure binary_trees_gc actually stresses GC. 2015-10-28 07:45:52 -07:00
Bob Nystrom b365c07d7a Add a benchmark that explicitly invokes the GC. 2015-10-24 11:00:17 -07:00
Bob Nystrom 0f7d4dd4d0 Add a timeout to the test runner. 
This ensures that when you run the tests while stress testing the GC,
that a pathological test won't hang forever.
 2015-10-24 10:58:21 -07:00
Bob Nystrom 720c03cf49 Add System.gc(). 2015-10-24 10:56:27 -07:00
Bob Nystrom f145662158 "Auxiliary" -> "optional". 
Fixes #309.
 2015-10-24 09:23:25 -07:00
Bob Nystrom 545a4cbf7e Style example output and errors in the docs. 2015-10-18 15:56:52 -07:00
Bob Nystrom 2174ff31e7 Merge pull request #308 from iwillspeak/master 
Add Will Speak to Authors File
 2015-10-18 10:35:14 -07:00
Bob Nystrom 30e7d9e508 Move core.wren to be next to wren_core.wren.inc. 2015-10-17 22:17:10 -07:00
Bob Nystrom e5176607d9 Move meta and random to "aux" modules. 
Wren now has three classes of modules:

- The one magic "core" module that's built in and always needed.
- Auxiliary libraries like "meta" and "random". These do not have any
  dependencies, so can be used even when you embed Wren inside an
  application. But they're also optional and can be disabled if you
  don't need them.
- CLI modules. These ones need libuv and are tied to the CLI wrapper
  around the VM.

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

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().
 2015-09-24 08:02:31 -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.

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
