As I said in the previous post, I'm trying to create a "Any Value" case type.
Another problem I have is supporting "seq[AnyValue]". Seq of anything else
seems to work. Maybe it's a type recursion problem? Is there a work-around?
Here's the example:
type
AnyValueType* = enum
avBool,
# ...
avBoolSeq,
# ...
avAnySeq
AnyValue* = object
case kind*: AnyValueType
of avBool: boolValue*: bool
# ...
of avBoolSeq: boolSeqValue*: seq[bool]
# ...
of avAnySeq: anyseqValue*: seq[AnyValue]
converter toBoolAnyValue*(v: bool): AnyValue {.inline, noSideEffect.} =
result.kind = avBool
result.boolValue = v
converter toBoolSeqAnyValue*(v: seq[bool]): AnyValue {.inline,
noSideEffect.} =
result.kind = avBoolSeq
result.boolSeqValue = v
converter toSeqAnyValueAnyValue*(v: seq[AnyValue]): AnyValue {.inline,
noSideEffect.} =
result.kind = avAnySeq
result.anyseqValue = v
when isMainModule:
let boolValue: bool = true
let boolValueAV: AnyValue = boolValue
let boolSeqValue: seq[bool] = @[boolValue]
let boolSeqValueAV: AnyValue = boolSeqValue
let anyseqValue: seq[AnyValue] = @[boolValueAV]
let anyseqValueAV: AnyValue = anyseqValue
assert(boolValueAV.boolValue == boolValue)
assert(boolSeqValueAV.boolSeqValue == boolSeqValue)
assert(anyseqValueAV.anyseqValue == anyseqValue) # Compiler bug :(
