Center curses output

mhearse has asked for the wisdom of the Perl Monks concerning the following question:

I have a curses app which is designed to run on a standard 80x25 console. By that I mean the output has a width of 80 characters and a height of 25 characters. When running this app in a terminal emulator I'm trying to figure out how to center my output. Can someone help me figure out how to calculate the beginning x,y coordinates?

Is this a Perl question? In order to get a useful answer you probably have to provide some details about your app. If your question is simply: on a screen of width $w and height $h and a centered window of 80x25, how wide is my left and top margin (or bottom?), the following should be helpful: `$left = ($w - 80) / 2; $top = ($h - 25) / 2;` [download] which both might be negative on a small screen.

Hi hdb, ..which both might be negative on a small screen... easy maths?! Huh!!! I remembered my programming days with V.B 6.0.. Nice one bro.. Update: hdb, am not undermining your point, am only emphasizing it... If you tell me, I'll forget. If you show me, I'll remember. if you involve me, I'll understand. --- Author unknown to me	[reply]

As I said, for a useful answer, more details might be needed...	[reply] [d/l]
