This is an example of a library. You may see a list of other libraries used on Rosetta Code at Category:Solutions by Library.
Wren-str is a module which supplements the methods in the Wren programming language's String class. It consists of static methods organized into 5 classes: Char, Str, Strs, Utf8 and Greek.
It is the second in a series of modules (listed on the language's main page) designed to assist with writing Rosetta Code tasks so the same code does not have to be written or copy/pasted time and time again thereby bloating a task's script code unnecessarily.
To use it all you need to do is to copy the source code (in the talk page) to a text file called str.wren and place this in the same directory as the importing script so the command line interpreter can find it.
