Is A Turtle or a Computer

Is there a way to determine in lua if the computer running the program is a turtle or a static computer?

NEVERMIND < I figured out:
if(turtle~=nil)then
–is turtle
else
–is computer
end

if turtle then
– is turtle
else
– is not turtle
end

local isTurtle = turtle ~= nil

I know you were just making an example, but the missing "then" is really bothering me :P/>/>

*GASP*
Cloudy made a noob mistake leaving out that 'then'.
Heh, I make that mistake all the time though.

give him a break, cloudy's busy doing java code all day, working on CC and CCSensors. In java, that was perfectly fine. :P/>/>

Well, when you put it that way, I guess I can give him some slack. Workin' hard to make the rest of us happy. GO CLOUDY, YOU CAN DO IT!

nothing like people going psycho on the forums to cheer you up :P/>/> lets all scream random stuff lol -rolls eyes-

Damn it! Edited :P/>/>

computerScreenSize = {51,19}
turtleScreenSize = {39,13}
actualSize = {term.getSize()}
if actualSize == computerScreenSize then
actualTerminal = "computer"
elseif actualSize == turtleScreenSize then
actualTerminal = "turtle"
else
actualTerminal = "monitor"
print("This terminal is a "..actualTerminal)

Cannot detect if run on a monitor (will print "This terminal is a monitor")

First off, it's missing an end.

computerScreenSize = {51,19}
turtleScreenSize = {39,13}
actualSize = {term.getSize()}
if actualSize == computerScreenSize then
actualTerminal = "computer"
elseif actualSize == turtleScreenSize then
actualTerminal = "turtle"
else
actualTerminal = "monitor"
end --## added the end here

print("This terminal is a "..actualTerminal)

Secondly, tables don't really work like that. They have the same values, but are entirely different objects, and won't come out as the same when compared. You'll probably just have to compare the tables' individual values. I would personally make a function for doing so for convenience.

function compare(first, second)
  for k,v in pairs(first) do
    if first[k] ~= second[k] then
      return false
    end
  end
  return true
end

computerScreenSize = {51,19}
turtleScreenSize = {39,13}
actualSize = {term.getSize()}
if compare(actualSize, computerScreenSize) then
  actualTerminal = "computer"
elseif compare(actualSize, turtleScreenSize) then
  actualTerminal = "turtle"
else
  actualTerminal = "monitor"
end --## added the end here

print("This terminal is a "..actualTerminal)

is there no way to see if the term has been redirected? can we not access the redirect stack? that would make everything sooo much easier

No, we can't access the redirect stack. One trick we can use is this:

if turtle and (term.getSize()) == 39 then
  --is a turtle.
elseif not turtle and (term.getSize() == 51 then
  --is a computer.
else
  --is a monitor. 
end
