Minimum Viable Editor | Line Editor in C #1
41Starting an ed clone as a "bootstrapped" line editor project.
I wanted to learn more about line editing historically, how the core of vim or other tools works, and if it's still useful as an editor or scripting tool today.
ed was probably written in assembly, with little to no headers or libraries.
I'm using C instead for some semblance of portability and an easier visual structure of the code, wanting to try some C23 features, and because I'm lazy.
Errata: ex is a program, not an extended mode of em (it is a non-visual mode of vi though!), that was a slip up.
