Rainbow Text!

Well, here is the story behind me making this:

This is pretty cool… as long as we don't start seeing rainbow text everywhere :P/>/>

There are two forms of this script, function adapted(ran behind code), or file adapted (Being ran in the CraftOS command-line like 'edit <path>') I basically made this just for fun, well, and to make oeed mad of course ;)/>

--[[Function Adapted]]--
local roygbiv = {
  colours.red,
  colours.orange,
  colours.yellow,
  colours.lime,
  colours.lightBlue,
  colours.blue,
  colours.purple
}

local function rainbow(text)
  local num = 1
  for i = 1,#text do
	local letter = string.sub(text,i,i)
	if num > #roygbiv then num = 1 end
	term.setTextColour(roygbiv[num])
	term.write(letter)
	num = num+1
  end
end

--Example:
--rainbow("Rainbow")

Or:

--[[File Adapted]]
local tArgs = {...}

if #tArgs <= 0 then
  print("Usage: "..shell.getRunningProgram().." <text>")
  return
end

local roygbiv = {
  colours.red,
  colours.orange,
  colours.yellow,
  colours.lime,
  colours.lightBlue,
  colours.blue,
  colours.purple
}

local num = 1
for i = 1,#tArgs[1] do
  local letter = string.sub(tArgs[1],i,i)
  if num > #roygbiv then num = 1 end
  term.setTextColour(roygbiv[num])
  term.write(letter)
  if num == #tArgs[1] then
	print("")
  end
  num = num+1
end

With the commandline version just type:

programName <textToColor>

Also, you may use this in your Graphical Shells as long as I am given full credit. This code CAN be modified for personal use, but nothing more.

Lol :P/>, nice. You should make it with more than just for 6 colors though :P/>.

It should be fully customizable (colour wise) as is.

Amazing….

It is indeed amazing what you can do with the proper knowledge. Now it's your turn. Excite our community and flourish into something incredible.

You could also do this for random colors, Just saying..

term.setTextColor(2 ^ math.random(1,15) )

But anyway this is pretty awesome as it is and I like it..
So you like rainbows? :3

Yes, yes I could. But this is fully customizable with interchangeable colours. So that is not an option.

Thanks, and I like rainbows to an extent. I don't really care for rainbow text all that much :P/>

Here you go :P/>.

local roygbiv = {
<Put Color 1 Here>;
<Put Color 2 Here>;
<Continue for as many colors as you want>;
}
local function rainbow(text)
  for i=1, #text do
	term.setTextColor(roygbiv[math.random(1, #roygbiv)]
	write(text:sub(i, i))
  end
end

I purposely made it a larger script than usual, so clueless members would understand what is happening on each line. I may compact it further, however it will stay as is for now.

I wasn't compacting it, I was giving you a version that uses math.random() instead of ordered colors because you said that it's not an option because you couldn't customized the colors, but you can :P/>.

The colours MUST go in order. If I wanted to randomize it, I would've ;)/> I didn't see the math.random in your script which is why I thought you were trying to compact it :P/>

Ah, OK, by "not an option" I thought you meant that there was no way to do it :P/>.

There is nothing impossible to him who will try
