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-iterate is a module which enhances Wren's built-in iteration facilities by providing the wrapper classes: Stepped, Reversed and Indexed plus a helper class SeqEntry. The first two of these enable sequences to be iterated in either (or both) a stepped fashion (steps > 1) or in reverse. The third enables the iteration to include the zero-based index of the sequence elements and SeqEntry assists with this.
It also contains:
- The Loop class which enables a parameterless function to be called repeatedly either for a fixed number of times or until some condition is met. The function is always called at least once.
- The Pipe class which iterates through a list of functions or fibers passing the output of each element to the next element in the list and returning the final result.
It is the forty-first 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 iterate.wren and place this in the same directory as the importing script or module so the command line interpreter can find it.
