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-long is a module which adds support for 64-bit integer arithmetic to the Wren programming language. It consists of 4 classes: ULong, Long, ULongs and Longs. The latter two contain static methods for dealing with lists of ULong and Long objects, respectively and instance methods for creating and iterating through ranges of such objects.
It is the nineteenth 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 you need to copy the source code (in the talk page) to a text file called long.wren and place this in the same directory as the importing script so the command line interpreter can find it.
As there is a dependency on the Wren-trait module, you also need to copy that (if it is not already present) to the same directory as described here. Unless you are using classes in that module directly, there is no need to import them into your script and the Comparable class can even be imported via Wren-long itself.
