I built a text editor in C (Part 2) – Entering into RAW mode using C

In this episode of the Build a Text Editor in C series, we’ll go deeper into raw mode — understanding exactly how terminal input works under the hood.

Here’s what we’ll cover in this video:

How the overall architecture of the text editor fits together

How to create and store the original termios backup safely

Understanding how to modify flag bits and why it matters

Setting up local flags to disable canonical mode and echo

Configuring input flags for precise control

Using VMIN and VTIME to manage input timing behavior

By the end, you’ll not only know how to enter raw mode, but why every flag and bit matters — mastering the foundation of every real terminal-based program.
