-- This is a set of common functions that
-- most of the system programs will use.

-- Always set the monitor peripheral.
local monitor = peripheral.wrap("back")

-- A generic function to allow us to print text
-- to the monitor at a specific location and in
-- a specific color.
function tp(textToPrint, column, row, fgcolour, bgcolour)
	monitor.setCursorPos(column, row)
	monitor.setTextColor(fgcolour)
	monitor.setBackgroundColor(bgcolour)
	monitor.write(textToPrint)
end

-- Clears the monitor.
function clear()
	monitor.setCursorPos(0, 0)
	monitor.setTextColor(colors.white)
	monitor.setBackgroundColor(colors.black)
	monitor.clear()
end

-- Menu Box
-- This function will create a clickable region
-- in a box format. You provide it with the
-- dimensions, label, and colour palette, and
-- it will return a table with the clickable
-- dimensions.
function menuBox(title, boxFG, boxBG, textFG, textBG, xA, yA, width, height)
	drawBox(boxFG, boxBG, xA, yA, width, height)
	tp(title, xA + 2, yA + 2, textFG, textBG)
end

-- Draws just a box.
function drawBox(boxFG, boxBG, xA, yA, width, height)
	local bline = ""

	for hCount = 0, height - 1, 1 do
		bline = ""
		for wCount = 1, width, 1 do
			bline = bline.." "
		end
		tp(bline, xA, yA + hCount, boxFG, boxBG)
	end
end
