String.split

Available since: Gideros 2022.1
Class: string

Description

Splits a string into parts based on the defined separator character(s), returning a table of ordered results.

(table) = string.split(separator)

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"

local values = input:split(",")
print(values[1], values[2], values[3])

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
