#
# Built-in objects
#
# YAML conventions:
#
# - Indent by two, indent lists of objects too.
# - Quoted used for keys, explicit string values, hex data, attributes.
# Not used for classes, built-in ID values, etc, unless necessary.
# - Double quotes used throughout to allow escaping.
#
# Top level object format is mostly self explanatory, a few notes:
#
# - The "id" string is used for referencing objects from property table
# - Class names must match array in genbuiltins.py
# - If the top level object is a function:
# - varargs: if true, function is vararg (nargs = DUK_VARARGS)
# - nargs: nargs (ignored if varargs true); if missing, default from 'length' property
# - magic: see below
# - native: native function name
# - callable: true/false, depending on function
# - constructable: true/false, depending on function
# - special_call: true/false, used for .call(), .apply(), etc which
# need special casing in runtime call handling
# - To disable an object without removing its metadata, you can
# use 'disable: true'.
# - If the object is dependent on Duktape configuration, you can make the
# object optional using e.g. 'present_if: DUK_USE_BUFFEROBJECT_SUPPORT'.
# If the value is a list, the object is present if all listed options are
# enabled (logical AND).
# - If the object needs a DUK_BIDX_xxx define in Duktape source code, which
# also implies it'll get a slot in thr->builtins[] array, use 'bidx: true'.
#
# Property format:
#
# - key: verbatim string key, codepoints U+0000...U+00FF map to bytes,
# so that \u0082 is 0x82 prefix, \u00FF is 0xFF prefix, etc. Key
# can also be a symbol, with the same format as for symbol values.
# - value: see below
# - attributes: string of format /w?e?c?a?/, e.g. "wc" is writable and
# configurable
# + w: writable
# + e: enumerable
# + c: configurable
# + a: accessor (determined automatically, not necessary to give explicitly)
# - auto_lightfunc: if true (which is default), function property may be
# automatically converted to a lightfunc if other automatic lightfunc
# conversion criteria are met; use "auto_lightfunc: false" to prevent
# lightfunc conversion
# - May also have feature tags like "es6: true" to indicate property
# is related to a specific standard
# - To disable a property without removing its metadata, you can use
# 'disable: true'.
# - If the property is dependent on Duktape configuration, you can make the
# property optional using e.g. 'present_if: DUK_USE_BUFFEROBJECT_SUPPORT'.
# List of options is interpreted as for objects (logical AND).
#
# Property value format:
#
# - ECMAScript undefined:
# - type: undefined
# - Plain YAML/JSON null (parses as Python None)
# - treated as ECMAScript null
# - Plain string:
# - treated as plain string, string data as with keys
# - Plain symbol:
# - type: symbol
# - variant: global, wellknown, hidden, userhidden
# - string: symbol string without any prefix
# - NOTE: ES2015 well-known symbols are local symbols with 'string' as
# their description, and a fixed suffix never overlapping with
# runtime local symbols
# - NOTE: "hidden symbols" are Duktape specific internal properties
# (called just internal properties in 1.x)
# - Plain number:
# - treated as a fastint/ieee double
# - IEEE double:
# - type: double
# - bytes: IEEE bytes in big endian format, hex encoded
# - NOTE: if you define a NaN, make sure it is in the Duktape normalized
# form (see bi_global 'NaN' property): otherwise strange things will
# happen with packed duk_tval
# - Buffer:
# - type: buffer
# - NOTE: not supported yet, type is reserved
# - Pointer:
# - type: pointer
# - NOTE: not supported yet, type is reserved
# - Lightfunc:
# - type: lightfunc
# - native: native function name
# - magic: -128 to 127
# - length: 0 to 15
# - nargs: 0 to 14; or varargs: true
# - varargs: if true, target has variable arguments
# - Reference to a built-in object:
# - type: object
# id: ID string of target object
# - Accessor (setter/getter):
# - type: accessor
# - getter_id: object ID of getter
# - setter_id: object ID of setter
# - Native function shorthand; alternative to defining a function as a
# native object and referencing it using an ID:
# - type: function (implicitly callable)
# - callable: default is true
# - constructable: default is false
# - native: native function name
# - length: function .length (optional, defaults to 0)
# - nargs: function nargs (optional, defaults to length)
# - varargs: if true, function is vararg (nargs = DUK_VARARGS)
# - magic: magic value for function (see below)
# - name: optional, provides .name property (non-writable, non-enumerable, non-configurable)
# - special_call: recognized in shorthand
# - Accessor (setter/getter) shorthand:
# - type: accessor
# - callable: default is true
# - constructable: default is false
# - getter: native function name
# - setter: native function name
# - getter_magic: magic value for getter
# - setter_magic: magic value for setter
# - getter_nargs: nargs value for getter
# - setter_nargs: nargs value for setter
# - getter_length: length value for getter (0 if missing)
# - setter_length: length value for setter (0 if missing)
# - Structured object shorthand:
# - type: structured
# - value: arbitrary JSON-like value
# - NOTE: value is converted into object(s) with properties
# similarly to JSON.parse() results: properties will be
# writable, enumerable, and configurable, inherit from
# Object.prototype, etc.
#
# Magic format:
#
# - Plain number: direct magic value
# - Array iterator magic:
# - type: array_iter
# - funcname: function name, e.g. "forEach"
# - Built-in object index:
# - type: bidx
# - id: id of built-object, idx to thr->builtins[]
# - One-argument math function:
# - type: math_onearg
# - funcname: name of function, e.g. "cos"
# - Two-argument math function:
# - type: math_twoarg
# - funcname: name of function, e.g. "atan2"
# - Typed array constructor
# - type: typedarray_constructor
# - elem: element type, e.g. "int8"
# - shift: shift for element size (0 = 1 byte element, 2 = 4 byte element etc)
objects:
# internal prototype: implementation specific
# Smjs: Object.prototype
