zipper -package:streams -package:traverse-with-class package:text-zipper

This module provides a two-dimensional text zipper data structure. This structure represents a body of text and an editing cursor which can be moved throughout the text, along with a set of editing transformations. Text zippers are generalized over the set of data types that might be used to store lists of characters (e.g., String, Text, etc.). As a result, the most general way to create a text zipper is to use mkZipper and provide all of the functions required to manipulate the underlying text data. Implementations using Text and String are provided.
A text editor zipper library This library provides a zipper and API for editing text.
