There are applications where ncurses is still a great approach for a controlled, structured UI, e.g., certain security appliances with complex configurations where web UIs, e.g., are not, by default, permissible.

(I spend a lot of time in ncurses on our appliances. We are looking at a web interface, but it will have to be homegrown and SELinux aware. It's a ways out yet....)

totally agree, there are a few nice books so really no need to repeat,but one covers new APIs from the last decade will be wonderful

it’s more like off topic given that ncurses/curses are ui-toolkits (hah !) than anything else.

Doesn’t top use ncurses?

And other utils like k9s
