Hi,

I noticed that you cannot return tables or functions from a peripheral method implemented in java. I don't need functions, but the lack of tables is really bad. luaj contains a huge conversion algorithm java <=> lua, but for some reason, ComputerCraft uses an own one which can only handle strings, integers, doubles, and null.

So, I would suggest using the luaj java <=> lua conversion for the peripherals.

You could always serialize them and unserialize them.

@Xfel:

function pack( ... )
  return arg
end

pack() takes an arbitrary amount of parameters, which is then accessible via the table 'arg' (which is then simply returned).
It's basically the opposite of what Lua's unpack() does.

Here's how you'd use the above function:

local periph = peripheral.wrap("right")
local tValues = pack( periph.getMultipleReturnValues() )

After the last line, 'tValues' will be a table with all the values that periph.getMultipleReturnValues() returned.

@Espen:
Yes, but that doesn't work if you want nested tables, dictionaries, or metatables

@Casper7526:
I'm currently using this solution, but it is more complicated than needed.
