Bob Nystrom 919605b7ba Couple of tiny tweaks. 2016-02-24 06:52:12 -08:00
Bob Nystrom 2c4e497c54 Fix a couple of doc bugs. 2016-02-22 07:48:53 -08:00
Bob Nystrom 60162575ee More file system checking functions: 
- Stat#isFile
- Stat#isDirectory
- Directory.exists()
- File.exists()
 2016-02-21 12:23:33 -08:00
Bob Nystrom c6148f8941 Make Stat a foreign class. 
Instead of copying the uv_fs_stat struct to a list of Wren numbers, we
store it directly in the Stat object. This is important because we'll
need to implement later methods like isDirectory() in C so we can use
S_ISDIR(). For that, we need to have access to the original stat data.
 2016-02-21 11:34:10 -08:00
Bob Nystrom b331915259 Add stat instance method to File. 2016-02-21 10:18:45 -08:00
Bob Nystrom 3101d9c499 Fix file flags to be OS-independent. 2016-02-20 17:25:41 -08:00

Bob Nystrom 8e90e3577b More file IO! 
Can now create, delete, and write to files.
 2016-02-20 09:23:42 -08:00
Bob Nystrom bec5181bdb Add separate targets for building just the shared or static library. 
make static
make shared

Running "make vm" will build both, as usual.

Fixes #322.

It's too slow on the Travis bots and times out.

Passing along a Variable lets us get rid of some duplicate code around
loading the class.
 2016-02-12 07:43:44 -08:00
Bob Nystrom 68f801a525 Unnecessary strncmp -> memcmp. 2016-02-12 07:27:42 -08:00
Bob Nystrom 5b5c258f55 Make a little Variable struct. 
Gets rid of the slightly ugly loadInstruction output parameter that
gets passed around. Now a reference to a variable is a first-class
concept in the compiler.

Bob Nystrom f19888d328 Merge branch 'master' of https://github.com/munificent/wren 2016-01-22 06:42:16 -08:00
Bob Nystrom 7e8bc2a89a Disable link-time-optimization for now. 
It's failing when building with clang on Travis. The underlying problem
seems to be something broken with how LLVM is looking for the gold
linker, and working around that is outside of my skillset.

Bob Nystrom 678251a00c Fix type for fileFinalizer(). 2015-12-29 21:07:26 -08:00
Bob Nystrom 2c31985e54 Make Directory.list() create and return a list from C. 2015-12-29 08:37:47 -08:00
Bob Nystrom e0ac88c22a Revamp wrenCall to work with slots. 
Now, you call wrenEnsureSlots() and then wrenSetSlot___() to set up the
receiver and arguments before the call. Then wrenCall() is passed a
handle to the stub function that makes the call. After that, you can
get the result using wrenGetSlot___().

This is a little more verbose to use, but it's more flexible, simpler,
and much faster in the VM. The call benchmark is 185% of the previous
speed.
 2015-12-29 07:58:47 -08:00
Bob Nystrom ed6fad6153 Get rid of fiber for finalizers. 
Instead, finalizers just get access to the foreign object's raw bytes.
This is deliberately limiting, since it discourages the user from
interacting with the VM in the middle of a GC.
 2015-12-28 08:06:29 -08:00
Bob Nystrom a447b66380 Make slots available to the API outside of foreign methods. 
At any point in time, the user can call wrenEnsureSlots() which will
implicitly create a fiber and point to its stack if needed.
 2015-12-28 07:49:47 -08:00
Bob Nystrom a09892de32 Use a fiber for a finalizer's foreign stack. 2015-12-27 21:43:08 -08:00

Bob Nystrom 910049cd19 Update the docs around slots. 2015-12-16 16:39:27 -08:00
Bob Nystrom 6f37d379f4 Add C API functions for working with lists: 
- wrenEnsureSlots()
  Lets you go the foreign slot stack to make room for a temporary work
  area.

- wrenSetSlotNewList()
  Creates a new empty list and stores it in a slot.

- wrenInsertInList()
  Takes a value from one slot and inserts it into the list in another.

Still need more functions like getting elements from a list, removing,
etc. but this at least lets you create, populate, and return lists from
foreign methods.
 2015-12-16 16:28:26 -08:00
Bob Nystrom 7fcdcf2f1a wrenReturn___() -> wrenSlotSet___(). 
This turns those functions into general-purpose functions for writing
raw C values into slots on the foreign call stack.

Writing a return just means writing a value to slot 0.
 2015-12-16 13:00:13 -08:00
Bob Nystrom 4b3c818ec5 Start moving embedding API towards "slot" register-API. 
- wrenGetArgumentCount() -> wrenGetSlotCount()
- wrenGetArgument___() -> wrenGetSlot___()

Also, the get functions assert that the value is the right type instead
of checking at runtime. This puts the onus on the caller to be safe,
but maximizes performance.
 2015-12-16 10:22:42 -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

 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.

Bob Nystrom 5bde04db4c Eagerly evaluate interpolated expressions. 
If we ever support custom string templates, we'll need to go back to

eagerly, leading to simpler code.

This allows "%(...)" inside a string literal to interpolate the

It doesn't support custom interpolators or format strings, but we can
consider extending that later.
