I don't think this is correct. This basically implements ESC[K and ESC[K0 but ESC[K1 erases from cursor to the beginning of line. And ESC[K2 erases the whole line.

Thank you for your comment.
I didn't understand, what do you think is the best way to do this?

I mean that at least it shouldn't accept ESC[K2. But ideally implementing it and ESC[K1 properly. There are also ESCj commands which move cursor and probably worth to be supported as well.

So does that mean I only need to style spaces and 0's here?
The pager won't clear the lines in 2, but the styling will work similarly.

You screenshot shows how it should work. Except for b3K which doesn't seem valid value.
So minimally we need K and 0K.
But ideally support 1K and 2K as well.

I got it. Work only with K and 0k.
But ideally support 1K and 2K as well.
It is still unknown whether it is more correct to work as a pager.
Thank you.
