A terminal based text editor built with C++ and ncurses. The editor focuses on fast keyboard driven editing, customizable themes, and lightweight performance in terminal environments.
Myst is designed for efficient text editing directly in the terminal. It handles user input, rendering, file operations, and a built-in command runner without relying on external editors, with a focus on responsiveness and control.
It also includes a terminal-style output panel for running system commands inside the editor.
