Anatomy of a Terminal Emulator
The terminal is a ubiquitous platform that has been fairly stable for many years. There are plenty of resources out there for understanding its inner workings, but most of them are either fairly arcane or offer deep knowledge about a very specific area. This post aims to bridge this gap by offering a gentle and broad introduction to the terminal emulator as a platform for development.
We’ll talk about the different parts of the terminal and how they interact, build a small program to read input from the shell and understand how it’s interpreted, discuss how to create a user interface in the terminal and finally see how we can use all of this to cause some mischief.
