term.redirect()

From what I understand, in LUA you can reference a function using a variable. For example:

a = function(n)
return n^2
end
print(a(2))

The above code will create a function, which takes a single variable and return its square.
So, in ComputerCraft we have a handy "term.redirect()" function. Perhaps, instead of passing this a monitor object we could pass it a table of functions? Seeing as you can access LUA table entries by non int based keys (for example a["cake"] = true) then why not use the function names (so a valid term.redirect() call would need a table with entries such as var["write"] = function(n), var["setCursor"] = function(n,n) and so on). This way, we could create our own objects, and redirect the computer's output to them.

For example, a remote control program could use term.redirect() to redirect output to its own functions that use rednet to send the output back to the controller.

Term.redirect already does this. It works with a monitor object because a monitor object is a table of term functions for the monitor.

Have you actually tried what you're suggesting here? I used exactly that numerous times. One of the applications I used it for was a monitor API that displays on the term as well and worked over rednet. So you can just do what you're describing here.

You can? I tried palying around with the various bits of CraftOS and it seemed much like the monitor object was all Java with a few IDs LUA side. I'll do some more wokr and see if I can get this to work :D/>/>.

Every API in CC is a lua table, the values stored under each key can be a reference to a java function or a lua function. What it references too is irrelevant, what is important is that the references are there and are of type function.

Ok. Thanks :D/>/>.
This will aid my turtles greatly in over taking the world.
