All Reflect functions specified in ECMAScript 2016 are implemented, and
most share Duktape/C helpers with their ES5 twins from Object.
* Reflect.apply()
* Reflect.construct()
* Reflect.defineProperty()
* Reflect.deleteProperty()
* Reflect.get()
* Reflect.getOwnPropertyDescriptor()
* Reflect.getPrototypeOf()
* Reflect.has()
* Reflect.isExtensible()
* Reflect.ownKeys()
* Reflect.preventExtensions()
* Reflect.set()
* Reflect.setPrototypeOf()
Presence of the Reflect object is controlled by DUK_USE_REFLECT_BUILTIN
and enabled by default in the standard configuration.
note: Reflect.enumerate() was retroactively removed in ES7, so it will
not be implemented in Duktape.
Change handling of plain buffers so that they behave like ArrayBuffer
instances to Ecmascript code, with limitations such as not being
extensible and all properties being virtualized. This simplifies
Ecmascript code as plain buffers are just lightweight ArrayBuffers
(similarly to how lightfuncs appear as function objects). There are
a lot of small changes in how the built-in objects and methods, and
the C API deals with plain buffer values.
Also make a few small changes to plain pointer and lightfunc handling
to improve consistency with how plain buffers are now handled.
* Add 'at foo' to indicate function name
* Put file/line into parentheses for better readability
* Use [anon] for anymous functions, which is better than an empty string but
distinguishable from a function actually named 'anon'
* Rename tailcalled flag to tailcall
* Switch from tab indent to 4 space indent
- Split built-in strings metadata into a separate YAML file.
- Split built-in objects metadata into a separate YAML file.
- Merge genstrings.py into genbuiltins.py to allow better refactoring.
- Automatic scan for string indices referenced by Duktape internals
(DUK_STRIDX_xxx, DUK_HTHREAD_STRING_xxx, etc), so that only those
strings are placed in heap->strs[].
- Add support for ROM built-in strings/objects.
- Change RAM init data format so that property keys can be either
stridx values or raw strings, so that heap->strs[] can be minimized.
