automatical line breaks

I have special area with information but I want to have auto line breaks like print()
So does anyone know how to do this?

Note: the text is form the user himself!

Hmmm, you'll need to be more clear on what you want to do. I cannot understand what you mean by "Auto line breaks" Though I'm assuming you want to know the regex for a new line in lua? well it's

n

*whoops, edited*

Why don't you use print?
If it's for a monitor, redirect the terminal to the monitor before printing, using term.redirect, and then use print.

I mean the user has input information and I want it to display it in a box e.g. 15x15
but I don't know how to :)/>/>

code:

function boxPrint(str)
  for n=1, math.floor(string.len(str) / 15) do
    write(string.sub(str, n*15,(n+1)*15).."n")
  end
end
boxPrint("This text will print in 15*15")

I didnt test it, but i think it will work…

Nope didn't work :)/>/>

Well I know that!
I only want to split the string at a space so it fits in the box:

e.g.:

+------------------+
| This is a text   |
| that fits in the |
| box!		   |
|		   |
|		   |
|		   |
|		   |
|		   |
|		   |
|		   |
|		   |
+------------------+

And why don't you copy the write code and change the size to the one you want?
write and print functions (from bios.lua):

function write( sText )
	local w,h = term.getSize() -- change the size here (eg: 15, 10)
	local x,y = term.getCursorPos()
	
	local nLinesPrinted = 0
	local function newLine()
		if y + 1 <= h then
			term.setCursorPos(1, y + 1)
		else
			term.scroll(1)
			term.setCursorPos(1, h)
		end
		x, y = term.getCursorPos()
		nLinesPrinted = nLinesPrinted + 1
	end
	
	-- Print the line with proper word wrapping
	while string.len(sText) > 0 do
		local whitespace = string.match( sText, "^[ t]+" )
		if whitespace then
			-- Print whitespace
			term.write( whitespace )
			x,y = term.getCursorPos()
			sText = string.sub( sText, string.len(whitespace) + 1 )
		end
		
		local newline = string.match( sText, "^n" )
		if newline then
			-- Print newlines
			newLine()
			sText = string.sub( sText, 2 )
		end
		
		local text = string.match( sText, "^[^ tn]+" )
		if text then
			sText = string.sub( sText, string.len(text) + 1 )
			if string.len(text) > w then
				-- Print a multiline word				
				while string.len( text ) > 0 do
				if x > w then
					newLine()
				end
					term.write( text )
					text = string.sub( text, (w-x) + 2 )
					x,y = term.getCursorPos()
				end
			else
				-- Print a word normally
				if x + string.len(text) > w then
					newLine()
				end
				term.write( text )
				x,y = term.getCursorPos()
			end
		end
	end
	
	return nLinesPrinted
end

function print( ... )
	local nLinesPrinted = 0
	for n,v in ipairs( { ... } ) do
		nLinesPrinted = nLinesPrinted + write( tostring( v ) )
	end
	nLinesPrinted = nLinesPrinted + write( "n" )
	return nLinesPrinted
end

You can simply copy that to your program, change the function names and the line that sets the size.

Thanks MysticT!
I thought that print is a "main" method that doesn't need to get rewritten in bios.lua

Edit: not finished yet B)/>/>
I want to use special x-coor but it always prints at the beginning of the screen B)/>/>

Does anyone know how to fix it? :)/>/>
