getting terminal display size?

[jeff]

I looked around a lot on the internet and couldn't find out how to do
this, how do I get the sizer (in rows and columns) of the view?

You use the TIOCGWINSZ ioctl() call on the tty device in question.

import termios, fcntl, struct, sys

s = struct.pack("HH HH", 0, 0, 0, 0)
fd_stdout = sys.stdout.file no()
x = fcntl.ioctl(fd_ stdout, termios.TIOCGWI NSZ, s)
print '(rows, cols, x pixels, y pixels) =',
print struct.unpack(" HHHH", x)

You may also want to handle the WINCH signal so that you know
when the window size has been changed.

I don't really understand any of that; can you right me a function
that'll return the size as a tuple?

Did you even *try* his code? I ran this:

import termios, fcntl, struct, sys

s = struct.pack("HH HH", 0, 0, 0, 0)
fd_stdout = sys.stdout.file no()
x = fcntl.ioctl(fd_ stdout, termios.TIOCGWI NSZ, s)
print '(rows, cols, x pixels, y pixels) =',
print struct.unpack(" HHHH", x)

And got this result:

(36, 96, 0, 0)

Looks like a tuple to me. return 'return' instead of 'print' the result.
We don't mind helping, but it's nice to know that the user has made some
attempt to understand what is going on before asking for free work to be
done.
