Description

Splits a string into parts based on the defined separator character(s), returning a table of ordered results. <syntaxhighlight lang="lua"> (table) = string.split(separator) </source>

If an empty "slice" is located, that part will be returned as an empty string. For instance string.split("abc||def", "|") will return a table with three strings: "abc", "", and "def"

<syntaxhighlight lang="lua"> local values = input:split(",") print(values[1], values[2], values[3]) </source>

Also note that whitespace from the original string will be preserved, for example string.split("abc _ def", "_") will honor the whitespace on both sides of the _ separator. By default, the separator character is , but you can specify an alternative character or series of characters
