lua-users wiki: Split Join
"split" [1] and "join"[2] are two common string operators that are essentially inverse operations of each other. Split separates a string containing a delimiter into the list of substrings between that delimiter. Join combines a list of strings into a new string by inserting a delimiter between each string. There are various ways to design and implement these functions in Lua, as described below.
