notepad--: A featureless text editor

notepad-- is a minimalist, featureless text editor. It supports the most basic text navigation and editing actions, and nothing else. Currently, it only supports ASCII text.

Installation

Make sure you have SDL3 and CMake installed

For example, on Arch:

sudo pacman -S cmake sdl3 sdl3_ttf
