Template:String split/doc

Template:String split is a convenience wrapper for the  function in Module:String2.

The  function splits text at boundaries specified by separator and returns the chunk for the index idx (starting at 1). It can use positional parameters or named parameters (but these should not be mixed): Any double quotes (") in the separator parameter are stripped out, which allows spaces and wikitext like  to be passed. Use   for the pipe character.

If the optional plain parameter is set to  then separator is treated as a Lua pattern. The default is plain=true, i.e. normal text matching.

The index parameter is optional; it defaults to the first chunk of text. A negative parameter value counts chunks backward from the end of the text.

Examples


Modules may return strings with | as separators like this:

Lua patterns can allow splitting at classes of characters such as punctuation: Or split on anything that isn't a letter (no is treated as false): Named parameters force the trimming of leading and trailing spaces in the parameters and are generally clearer when used: A negative index will count back from the end of the text: An easy mistake to make when using negative parameters is to forget that a trailing space in the text when passed as an unnamed parameter will induce an empty last chunk:
