Monitor text, make new lines?

So I'm working on a computer program for a server I play on, and its going to be in the spawn. So im setting up a rules function, and everything's working except for the fact, I cant use mon.print(" ")

All I can use for text is mon.write("") and I cant figure out how to make the text go to a new line. Keep in mind, this is a function in an ongoing program, not monitor right blah.

Can anyone help me?

I haven't read that much about monitors, but shouldn't mon.write ('n') do the trick?

I thought it would, but when I have

mon.write ("Rule 1: n")

It shows a question mark. And when I have it outside of quotations, it throws an error.

I believe it's /n. Also why don't you use mon.setCursorPos?

Edit: dammit I was wrong again :P/>/> keep on getting the / and mixed up

/n inside quotations just displays Rule 1: /n.
And /n outside, gives an error for trying to use arithmetic on a string.

And Because i have over 10 lines of rules, i was trying to make it seem a bit neater. But If nothing else works, Ill just try that :P/>/>

The easier way would be to redirect the terminal output and then use print:

local mon = peripheral.wrap("<side>") -- I guess you already know this
term.redirect(mon) -- redirect the output to the monitor
print("Hello World!!") -- use print, write, and any function that uses the terminal, it will show in the minitor
term.restore() -- after printing everything, restore the output to the terminal

BTW, this is how the monitor program works.

Awesome! This will work perfect, thank you!

If you want to make a new line, you could also use setCursorPos,
so for example, you would have

local mon = peripheral.wrap("<side>") – I guess you already know this
term.redirect(mon) – redirect the output to the monitor
print("Hello World!!") – use print, write, and any function that uses the terminal, it will show in the minitor
term.restore() – after printing everything, restore the output to the terminal
as MysticT said, But if you want to make another line for rules example it would be like this:

local mon = peripheral.wrap("<side>")
term.redirect(mon)
mon.setCursorPos(1,1)
print("Rules:")
mon.setCursorPos(1,2) – this sets it to the second line
print("1: No Griefing!")
term.restore()

and so forth, it should work, it's how I did it with mine. Goodluck!!

And why don't you just do:

local mon = peripheral.wrap("<side>")
term.redirect(mon)
print("Rules:")
print("1: No Griefing!")
-- All the prints you want here
term.restore()

It would have the same effect, since print already moves the cursor to the next line.

Oh ok, I'm new to this I didn't know! Thanks! :P/>/>

I have a question: can you do the following?

local function redirector(side)
  term.redrect(peripheral.wrap(side))
  local temp={}
  for k,v in pairs(term) do
    temp[k]=v
  end
  term.restore()
  return temp
end

and that will return a table of functions including the print one

If you feel really abitious, you could write a whole new write function just for your program that automatically adds a new line break into your strings as you call back to it.

there's no print function in the term, it's a global that just uses term's write and get/setCursorPos functions, so… nope, sorry

the print function isn't magic, though. You could implement your own easily enough…

function printTo(device,text)
  local lines={}
  --break into lines on ns
  --we add a n at the end, so it behaves like print and so the match can find the last line
  string.gsub(text.."n","(.-)n",function(v) lines[#lines+1]=v end)
  local _,row=device.getCursorPos()
  local _,height=device.getSize()
  for i=1,#lines do
	--write the line
	device.write(lines[i])
	--move to next row
	row=row+1
	--if this went off the screen, scroll
	if row>height then
	  row=height
	  device.scroll(1)
	end
	--set to start of next line
	device.setCursorPos(1,row)
  end
end

:edit2: note that this doesn't support tabs (t).

Also, it would return the term api functions, wich don't change when you redirect, they are always the same.

What about using multiline strings?

mon.write [[
Rules
---------
1. Follow rule #2
2. Follow rule #3
3. Follow rule #1
]]
