cli Simple Dialog CLI

I am working on making another program and needed to port some old code from computer craft so I figured I may as well share. This file conaints 2 types of menus, a vertical list which takes an array and optional header text, and a yes/no style menu that can be customized.

local term = require("term")
local event = require("event")
local methods = {}
 
function methods.list(m, header)
  header = header or "Menu List"
  n=1
 
  while(true) do
    term.clear()
    term.setCursor(1,1)
    term.write(header)
    term.setCursor(1,2)
 
    for i=1, #m, 1 do
      if(i==n) then
        term.write(" [" .. m[i] .. "]\n")
      else
        term.write("  " ..  m[i] .. "\n")
      end
    end
 
    local _,_,_,key = event.pull("key_down")  
 
    if(key==200 and n>1) then --go up
      n = n-1
    end
    if(key==208 and n<#m) then --go down
      n = n+1
    end
    if(key==28) then --exit
      break
    end
  end
 
  term.clear()
  term.setCursor(1,1)
  return n
end
 
function methods.dialog(prompt, lOpt, rOpt)
  prompt = prompt or "Continue"
  lOpt = lOpt or "YES"
  rOpt = rOpt or "NO"
 
  local n = 1
 
  term.write(prompt.."\n")
 
  while true do
    local x, y =term.getCursor()
    term.clearLine()    
   
    if n==1 then
      term.setCursor(x, y)
      term.clearLine()
      term.write ("["..lOpt.."]   "..rOpt)
    else
      term.setCursor(x, y)
      term.clearLine()
      term.write(" "..lOpt.."   ["..rOpt.."]")
    end
 
  term.setCursor(x, y)  
  local _,_,_,key = event.pull("key_down")  
 
  if key==203 then n=1 end
  if key==205 then n=2 end
  if key==28  then term.write("\n") return n end
  end
end
 
return methods
