How do i capture both key and a char event in the os.pullevent

while true do
  local event, param1 = os.pullEvent()
  if event == "key" then
    -- key was pressed
  elseif event == "char" then
    -- key with a char was pressed
  end
end

it prints both though

function read() do
  local input = ""
  while true do
	local event, p = os.pullEvent()
	if event == "char" then
	  input = input..p
	elseif event == "key" then
	  if p == keys.enter then
		return input
	  elseif p == keys.backspace then
		input = input:sub(1, #input - 1)
	  end
	end
  end
  error( "should never get here" )
end

keys = {}
while true do
  keys[1]=""
  keys[2]=""
  local event, param1 = os.pullEvent()
  if event == "key" then
    key[1] = param1
  elseif event == "char" then
    key[2] = param2
  end
end

i could do

keys = {}
while true do
  keys[1]=""
  keys[2]=""
  local event, param1 = os.pullEvent()
  if event == "key" then
	key[1] = param1
  elseif event == "char" then
	key[2] = param2
  end
end

ill just have to modify your coded so that it prints out the key every time instead of after the enter

function read() do
  local input = ""
  local cx,cy = term.getCursorPos()
  while true do
	local event, p = os.pullEvent()
	if event == "char" then
	  input = input..p
	elseif event == "key" then
	  if p == keys.enter then
		return input
	  elseif p == keys.backspace then
		input = input:sub(1, #input - 1)
	  end
	end
	term.setCursorPos(cx,cy)
	write(input.." ")
  end
  error( "should never get here" )
end

write("Your name: ")
local name = read()

write("Your pass: ")
local pass = read("*")

function read( mask )
  -- .... other code here

  term.setCursorPos(cx,cy)
  write( ( mask and string.rep(mask, #input) or input ).." ")
end
