There's no escaping it: an exploration of ANSI codes

ANSI escape codes, a nearly 50-year-old standard originating from 1979, remain the backbone of modern terminal styling and interaction, enabling features like colored text, progress bars, and cursor positioning through special character sequences. These codes work by embedding escape sequences (starting with ESC character followed by brackets) into text streams that terminal emulators interpret as commands rather than displayable characters. Modern applications and libraries continue to build upon this simple standard to create sophisticated interactive terminal UIs, from basic color formatting to complex tools like Vim and htop.
