Class: string
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
Corner Cases
Empty String
<syntaxhighlight lang="lua"> "" --> "" </source>
Empty Slices
<syntaxhighlight lang="lua"> "foo,,bar" --> "foo", "", "bar" ",foo" --> "", "foo" "foo," --> "foo", "" "," --> "", "" ",," --> "", "", "" </source>
Whitespace Preserved
<syntaxhighlight lang="lua"> " whitespace " --> " whitespace " "foo , bar" --> "foo ", " bar" </source>
Invalid UTF-8
<syntaxhighlight lang="lua"> "\xFF" --> "\xFF" "\xFD,\xFE" --> "\xFD", "\xFE" </source>
Unicode
<syntaxhighlight lang="lua"> "，" --> U+FF0C FULLWIDTH COMMA "我很高兴，你呢？" --> "我很高兴", "你呢？" "•" --> U+2022 BULLET "hello•world" --> "hello", "world" </source>
Parameters
separator: (string) separator character(s) to be used for splitting the string optional, default value ","
Return values
Returns (table) table of ordered results
