--[[

This module is intended to provide access to basic string functions.

Most of the functions provided here can be invoked with named parameters,

unnamed parameters, or a mixture. If named parameters are used, Mediawiki will

automatically remove any leading or trailing whitespace from the parameter.

Depending on the intended use, it may be advantageous to either preserve or

remove such whitespace.

Global options

ignore_errors: If set to 'true' or 1, any error condition will result in

an empty string being returned rather than an error message.

error_category: If an error occurs, specifies the name of a category to

include with the error message. The default category is

[Category:Errors reported by Module String].

no_category: If set to 'true' or 1, no category will be added if an error

is generated.

Unit tests for this module are available at Module:String/tests.
