Building a Text Editor in Haskell, Part 1

27 Mar 2024

I am building a little text editor in Haskell.¹ Why would I do such a thing? Because I’m in a class and this fulfills the requirement, and building a text editor is the kind of thing that I’ve always wanted to take a crack at.

This is part 1, and I will describe how to build a rope data structure in Haskell. A rope is a bunch of strings (literally, and in the CS sense) and is optimized for cheap edits. You can see my implementation on Codeberg.
