Re: How to interpret ansi escape code like "\033[; 1; 31mHello World\033[0m"?

[John Daker]

Hi, again

I've read some source you guys mentioned, and got more confused...

What's relationship of vt100,xterm,escape code, how vim produce/explain ?

What I'm doing is a program that fork a pty to exec programs like
'vim', and I use ncurses to display what I read from pty.
So I have to deal with escape code.
I've tried some google, and got more confused when 'vt100' 'vt520',
'xterm' ....comes up.

My question is where should I start?
Where can I get the whole escape code list?
Which part of the list should I interpret in my program to make sure
'vim','top' and so on can work properly?

Thanks
