Changing colours of text in a single print/write?

Is it possible without separate prints/writes?

print("This colour is " .. term.setTextColour(colours.red) .. "red and this is " .. term.setTextColour(colours.yellow) .. "yellow.")

Technically yes, but not by default. I actually made a function like this for one of my programs a while ago. The concept of it is pretty simple, a function that can be called with a variable number of arguments, and it has a local curColor variable. When going through the arguments, if the current arg is a color, it sets curColor to that color, and if it's a string, it writes the string.

local function colorPrint(...)
  local curColor
  for i=1, #arg do -- arg is ...
    if type(arg[i]) == 'number' then
      curColor = arg[i]
    else
      if curColor then
        term.setTextColor(curColor)
      end
      write(arg[i])
    end
  end
  print() -- this is a print function, so it needs a new line.
end

So then you could do

colorPrint(colors.lightBlue, 'This is light blue, ', colors.yellow, 'and this is yellow.')

That's awesome, thanks :(/>/> I tried for quite a while to make a function like this :(/>/> Is there a way you could use the function like this:

colorPrint(lightBlue, 'This is light blue, ', yellow, 'and this is yellow.')

so you don't have to type colours. before the colour?

Well, the most I can do without much effort is have you put the colors in quotes.

colorPrint('lightBlue', 'This is light blue, ', 'yellow', 'and this is yellow.')

Here's the new function.

local function colorPrint(...)
  for i=1, #arg do
    if i%2 == 1 then
      term.setTextColor(arg[i])
    else
      write(arg[i])
    end
  end
  print() -- this is a print function, so it needs a new line.
end

However it REQUIRES that every odd argument is a color name. So you can't do this:

colorPrint('Some text', 'red', 'lightBlue')

You could also use the first function, while basically redefining every color as a global variable

local lightBlue = colors.lightBlue
local red = colors.red
local yellow = colors.yellow

or do the above using _G

for i, v in pairs(colors) do
  if type(v) == 'number' then
    _G[v] = v
  end
end

But I'm definitely overthinking this ahahaha
