This is a small repo for storing some information related to ANSI-VT100 control sequences.

I used it in some of my Node.js or Python projects and it was a bit bizzarre to work with inside CMD on Windows, hence I made a tiny knowledge stash, which I will likely expand further. I actually forgot what exactly I was going to do with it. I believe that I created some kind of mini colors library that I could use for printing out colorful debug messages. Makes sense in that aspect I guess...

I might want to give it another try when I have some time the other day.
