--[[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 willautomatically remove any leading or trailing whitespace from the parameter.Depending on the intended use, it may be advantageous to either preserve orremove 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 [Kategoria:Dagiti biddut nga inreporta babaen ti Modulo 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 Modulo:String/subokan.]]localstr={}--[[lenThis function returns the length of the target string.Usage:{{#invoke:String|len|target_string|}}OR{{#invoke:String|len|s=target_string}}Parameters s: The string whose length to reportIf invoked using named parameters, Mediawiki will automatically remove any leading ortrailing whitespace from the target string.]]functionstr.len(frame)localnew_args=str._getParameters(frame.args,{'s'})locals=new_args['s']or''returnmw.ustring.len(s)end--[[subThis function returns a substring of the target string at specified indices.Usage:{{#invoke:String|sub|target_string|start_index|end_index}}OR{{#invoke:String|sub|s=target_string|i=start_index|j=end_index}}Parameters s: The string to return a subset of i: The fist index of the substring to return, defaults to 1. j: The last index of the string to return, defaults to the last character.The first character of the string is assigned an index of 1.

The first character of the string has index 1. Defaults to 1. match: In some cases it may be possible to make multiple matches on a single string.
