ChunkSplit

Split a string into groups of "length" each ending with "endChars" (identical to the PHP function of the same name).

table = &lt;PREFIX&gt;_ChunkSplit(string [, length [, endChars]])

Arguments

 * string : String - containing words that you would like split.
 * length : Integer - number of characters to split the string by. Default is 76.
 * endChars : String - Add this to the end of each chunk. Default is "\n".

Returns

 * chunks: Table - array of chunks

Example
chunks = &lt;PREFIX&gt;_ChunkSplit("World of Warcraft", 2)

Result
chunks = { "Wo\n", "rl\n", "d \n", "of\n", " W\n", "ar\n", "cr\n", "af\n", "t\n", }

Code
function &lt;PREFIX&gt;_ChunkSplit(string, length, endChars) if not string then return {} end -- Sanity check: make sure length is an integer. length = floor(tonumber(length)) if not length then length = 76 end if not endChars then endChars = "\n" end local Table = {} for i=1, strlen(string), length do       table.insert(Table, strsub(string, i, i + length) .. endChars) end return Table end
