# Category:Wren-seq

**Library**

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-seq** is a module which supplements the methods in the Wren programming language's Sequence and List classes with static methods in the Seq and Lst classes respectively.

It also adds new list-based FrozenList and Stack classes which do what you would expect from their names.

It is the sixth 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 *seq.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 *Cloneable* and *CloneableSeq* classes can even be imported via Wren-seq itself.
