Like the edit program how can I print something that can then be edited?

[oeed]

By print do you mean on screen print or paper print?

Print on screen then be able to edit it.... Like the program edit.

[immibis]

You can do it by copying the edit program into your program

[oeed]

Print only draws text to the screen. Making it editable is not a trivial task. I recommend you take a look at edit. What do you need this for?

I am also interested in this, for like a config file, so you don't have to go into the config file to change options.

So basically you want to make something simliar to the adress bar on your browser?

[Kryptanyte]

Yeah

I looked at the edit program and it seems to just return lines. I dont know how this works

This isn't all the code, and its really basic, but here is the start of what you need to do

local function editableInput( initial, mask )
  local sx, sy = term.getCursorPos()
  while true do
	local event, param = os.pullEvent()
	if event == 'key' then
	  if param == key.backspace then
		initial = initial:sub( 1, #initial - 1 )
	  end
	elseif event == 'char' then
	  initial = initial..param
	end
  end
  term.setCursorPos(sx,sy)
  if mask then
	write( string.rep( mask, #initial )..' ' )
  else
	write( initial..' ' )
  end
end

@TOB What exactly is the mask? Like I see where is it used, but don't fully understand what it is.

Its like when you do read( '*' ) for password input. it "masks" the input.

Oh, I see thank you

[theoriginalbit]

no problems.

if all you want is a single line of editable input, basically read() that can be pre-loaded with a value, you can simply queue an up arrow key event before calling read, and pass the initial value in a table as the 2nd argument to read, as so:

os.queueEvent("key",keys.up)
read(nil, { "initial value" })
