Sami Vaarala	5ed6bb980b	Add initial, minimal ES6 Symbol support * Strings with 0xFF byte prefix are considered special symbols: they have typeof "symbol" but still mostly behave as strings (e.g. allow ToString) so that existing code dealing with internal keys, especially inside Duktape, can work with fewer changes. * Strings with 0x80 byte prefix are global symbols, e.g. Symbol.for('foo') creates the byte representatio: 0x80 "foo" * Strings with 0x81 byte prefix are unique symbols; the 0x81 byte is followed by the Symbol description, and an internal string component ensuring uniqueness is separated by a 0xFF byte (which can never appear anywhere in an extended UTF-8 string). The unique suffix is up to Duktape internals, currently two 32-bit counters are used. For example: 0x81 "mySymbol" 0xFF "0-17". * Well-known symbols use the 0x81 prefix but lack a unique suffix, so their format is 0x81 <description> 0xFF. * ES6 distinguishes between an undefined symbol description and an empty string symbol description. This distinction is not currently visible via Ecmascript bindings but may be visible in the future. Append an extra 0xFF to the unique suffix when the description is undefined, i.e. 0x81 0xFF <unique suffix> 0xFF.	8 years ago

Sami Vaarala	2d43ef8c04	String.prototype.repeat(), internal buf zeroing	8 years ago
Sami Vaarala	0fa879e6d3	Add internal duk_dup_xxx() helpers Saves a few hundred bytes of footprint: * duk_dup_0() = duk_dup(ctx, 0), duk_dup_1() = duk_dup(ctx, 1), etc. * duk_dup_m2() = duk_dup(ctx, -2), etc. * duk_dup_m1() is not added, because duk_dup_top() is the same thing	8 years ago

Sami Vaarala	96d301b3cb	Rename src/ to src-input/ to match dist With this change the directory naming in the main repo and dist is the same.	8 years ago
Sami Vaarala	a7f1adaf63	Remove Duktape specific error subtypes These don't play well with the API currently: the Duktape specific error codes don't have Ecmascript Error class counterparts so they don't get represented usefully as Ecmascript objects (e.g. AllocError is a plain Error from Ecmascript point of view). There's no real need for Duktape specific error code. Some of the codes had become unused; a couple were used but Ecmascript standard types can be used instead. Also minor error message tweaking.	9 years ago
Sami Vaarala	1245df1e12	Reduce error call site footprint, internal changes * Use shared error macros and shared error handler to reduce the size of call sites of common errors. * Make zero argument DUK_ERROR() calls non-vararg calls to reduce call site footprint. Non-vararg calls have smaller call sites and because there are a lot of call sites, this turns out to be significant. * Remove variadic macros from internal DUK_ERROR() macro set and add separate macros for argument counts 0 to 4; this is more portable and requires less conditional code, and works well when a non-vararg call is used for most error call sites. * Rework macro / function argument order for the error path, try to keep 'thr' in the same argument slot to avoid unnecessary register moves. * Pack linenumber and error code into a single 32-bit argument when possible, removes one more constant load from the call site. * Convert some internal errors to RangeErrors when the underlying cause is an implementation limit (such as a compiler temp limit) rather than an actual unexpected internal situation. * Simplify and share a few error messages to reduce string count.	9 years ago

Sami Vaarala	22a38b4b07	Fastint fast paths and cleanups Change a few built-ins to treat length as a 32-bit quantity even though the specification allows some operations to extend the Array length above 2^32-1. This is not very useful, because it will be read back through ToUint32().	10 years ago
Sami Vaarala	6e5acddedf	Fix MSVC warnings caused by const differences	10 years ago
Sami Vaarala	a2b9e32e9e	Add duk_def_prop(), rework defineProperty() Add a C API binding for Object.defineProperty(): duk_def_prop(). In addition to Object.defineProperty() features, the API call provides a "force" flag which allows properties to be added to non-extensible objects and non-configurable properties to be changed (except virtual properties which are immutable). Because the name duk_def_prop() conflicts with internal calls, rename them from duk_def_prop() to duk_xdef_prop(). This rename also makes it clearer that the internal duk_xdef_prop*() calls have non-compliant, internal semantics. Also reimplement Object.defineProperty() and Object.defineProperties() (and duk_def_prop()) so that they share the same internal helpers, and there is no need for a temporary property descriptor object which is unnecessary churn. Detailed changes: - New helper to prepare (validate and normalize) property descriptors - New helper to implement Object.defineProperty() internals, leaving out validation of the property descriptor - Reimplement Object.defineProperty() using the new helpers - Reimplement Object.defineProperties() using the new helpers - Reimplement duk_define_property() using the new helpers, so that a temporary property descriptor object is no longer created - Add support for "force" flag to Object.defineProperty()	10 years ago

Sami Vaarala	b14964986d	Add macros for defining properties with WEC attrs Also change call sites to use these macros. For now, the macros just call the existing def_prop_xxx() functions, but because there are relatively many call sites, these can be footprint optimized later.	11 years ago
