Is there a way to convert tArgs to a string value?

This is a program called run which simply sends a global message of what ever program you want to run


local tArgs = {...}
rednet.broadcast(tArgs)

The other computers/turtles have this code


event,id,message = os.pullEvent(rednet_mesage)
os.run(message)

and they give this error


bois:336: Expected String, string

Any possible fixes?

Instead of the tArgs in rednet.broadcast:
If there's only one argument, use tArgs[1]. If there can be multiple, use unpack(tArgs)

Also, use shell.run() instead of os.run(). It's easier.

I think a better way is to serialize it…


local strVersion=textutils.serialize(tArgs)
rednet.broadcast(strVersion)

then once you receive the message on the other side use textutils.unserialize to convert it back

Its actually up to what the purpose of this is. If this is an user based message, I would use table.concat:


local tArgs = {...}
rednet.broadcast(table.concat(tArgs, ' ')) -- open rednet first!
