Ropes in Go

A value-oriented, immutable, functional rope in Go.

Introduction

This module provides an implementation of the rope data structure in Go. Ropes allow for the efficient manipulation of long strings of text.

The rope structure implemented by this module is immutable, value-oriented, and immutable.

There is no way to modify an existing rope: all operations on a rope return a new rope.

One notable use case that this makes particularly nice is undo/redo: simply keep the old versions of the rope around.

Example

A simple example:

	rope := NewString("hello")
	rope = rope.AppendString(", world!")
	fmt.Printf("The value of the rope is: %v\n", rope.String())
