I'm trying to iterate over a JArray in NLua, but can't somehow.
JArray's are treaten as userdata (what is userdata?) and thus can't be iterated over.
Converting the JArray to an JValue[] with a c# method doesn't work either.
There are two possible solutions as far as I can see. 1. Getting a working Iterable function for nlua. 2. Converting the JArray to a Lua Table and then use a for loop on top of it.
I have not succeeded at any of those two. Is there anyone with more experience on this? Thank you in advance.
things I tried:
regCommands is a JArray containing a lot of JObjects in JTokens
jArray = Json:parseJArray(regCommands)
for k, v in ipairs(jArray) do
print(k.. " ".. v)
end
this gives the error on ipairs(jArray) that jArray is userdata.
Json:parseJArray(JArray)
is a c# function wich takes a JArray and spits out a JToken[]
something else I tried:
keyVal = regCommands.First
while keyVal ~= nil do
if (type(JProperty)) then
regCommands[keyVal.Name:lower()] = keyVal.First
end
keyVal = keyVal.Next
end
this crashes at
regCommands[keyVal.Name:lower()] = keyVal.first
whitout any logical reasons.
even getting a c# enumerator doesn't work
enumCommands = regCommands:GetEnumerator()
enumCommands:MoveNext()
repeat
enumCommands:MoveNext()
until enumCommands:Current() ~= nil
To iterate over a .NET collection you can use luanet.each function, which will return the function to iterate through .NET enumerables objects.
local each = luanet.each
for k in each(jArray) do
print (k)
end
