This changes some constructs like this
struct FmtScope {
enum value { Local, Global };
};
struct GroupType {
enum value { NoType, Seq, Map };
};
struct FlowType {
enum value { NoType, Flow, Block };
};
into this
enum class FmtScope { Local, Global };
enum class GroupType { NoType, Seq, Map };
enum class FlowType { NoType, Flow, Block };
The full list of pseudo enum classes now turned into real enum classes:
enum class State { WaitingForSequenceEntry, WaitingForKey, WaitingForValue };
enum class EmitterNodeType { NoType, Property, Scalar, FlowSeq, BlockSeq, FlowMap, BlockMap };
enum class Type { Verbatim, PrimaryHandle, NamedHandle };
enum class EmitterStyle { Default, Block, Flow };
enum class iterator_type { NoneType, Sequence, Map };
enum class NodeType { Undefined, Null, Scalar, Sequence, Map };
enum class CollectionType { NoCollection, BlockMap, BlockSeq, FlowMap, FlowSeq, CompactMap };
enum class FmtScope { Local, Global };
enum class GroupType { NoType, Seq, Map };
enum class FlowType { NoType, Flow, Block };
enum class StringFormat { Plain, SingleQuoted, DoubleQuoted, Literal };
enum class StringEscaping { None, NonAscii, JSON };
