[Lua] How do I read strings from another file?

s_mainDir = "Omega/"
s_infoFile = "infoText.txt"
s_fullPath = s_mainDir .. s_infoFile


if not fs.isDir(s_mainDir) then	fs.makeDir(s_mainDir) end
if not fs.exists(s_fullPath) then file = fs.open(s_fullPath, "w") file.close() end

function printText()
	t_info = {}
	i = 1
	fileHandle = fs.open(s_fullPath, "r")
	if fileHandle then
		line = fileHandle.readLine()
		repeat
			table.insert(t_info, line)
			line = fileHandle.readLine()
		until line == nil
	end
	fileHandle.close()
	for i = 1, #t_info do
		print(t_info[i])
	end
end

function addText(text)
	fileHandle = fs.open(s_fullPath, "a")
	if fileHandle then
		fileHandle.writeLine(text)
	end
	fileHandle.close()
end

while true do
	term.clear()
	term.setCursorPos(1,1)
	printText()
	repeat
		e = {os.pullEvent()}
	until string.lower(e[2]) == "r"
end
