A metatable in Lua defines various extraneous behaviors for a table when indexed, modified, interacted with, etc. They are Lua's core metaprogramming feature; most well known for being useful to emulate classes much like an OOP language.
Any table (and userdata) may be assigned a metatable. You can define a metatable for a table as such:
-- Our sample table
local tab = {}
-- Our metatable
local metatable = {
-- This table is then what holds the metamethods or metafields
ANSI escape sequences can be printed to a shell to as instructions. The below is a list of codes I have used often in my CLI programs and I find myself looking up over and over again.
A great article about it can be found here.
