Tables, functions, etc. in lua are pointers that refer to a memory slot, therefor they should be saved as binary code.
What i've been searching for is a way to "read" that pointer as an array of bytes, but i haven't found any solutions for this anywhere (even not in the lua users forum).
I want to use this for example to send and receive tables and functions, as bytes are numbers and you can send or receive them via rednet or redpower bundled cables...

I hope anyone knows if or how this is possible...

String.dump(f) will allow you to send simple functions which contain no upvalues.

Rednet doesn't work with string dump. just use the textutils api specifically serialize and unserialize to send your tables as strings.

Just a side note. if you're using CC1.5+ you can no longer use the RP2 bundled cables for Rednet.

[JokerRH]

Using the textutils api I cannot serialize functions, that's why I hoped you could read the machine code directly...
And to the RP2 bundled cables: I didn't know it was possible to use them as rednet...I just thought about creating a serial comunication

More accurately, Events don't work with string.dump

You could write a custom serialisation. but sadly, since the rednet api doesn't support some of the chars that would exist when dumping a function........ pastebin, then send the paste bin link over rednet, anyone? (please don't take that seriously)... maybe encoding the dump to base64 could work, since rednet is designed, kinda, for ASCII and not binary...

Same difference, still doesn't work.
