what version ... os.get_terminal_geometry() ...

[Skaperen]

ok, it will be easy to switch to shutil. i decided that since i would need to do an import anyway (of sys to check the minor version) that i could just do from os import get_terminal_size in try/except where i def get_terminal_geometry(): one of two different ways (eliminating testing this in the function call). replacing os with shutil will be trivial.

the code:

try:
    from shutil import get_terminal_size
    def get_terminal_geometry(fd=1):
        """Get current terminal geometry (width,heght)
    
function        get_terminal_geometry
purpose         get terminal geometry (width,heght)
arguments       (1,fd=) open file or file descriptor of tty to get geometry from
return          (width,height)
"""
        return get_terminal_size(fd)
except ImportError:
    def get_terminal_geometry(fd=1):
        """Get current terminal geometry (width,heght)
    
function        get_terminal_geometry

return          (width,height)
"""
        import fcntl,os,struct,termios
        if 'fileno' in dir(fd):
            fd=fd.fileno()
        try:
            height,width=struct.unpack('4H',fcntl.ioctl(fd,
                termios.TIOCGWINSZ,
                struct.pack('4H',0,0,0,0)))[:2]
        except:
            height,width=None,None
        if height is None or width is None:
            try:
                fd = os.open('/dev/tty',os.O_WRONLY)
                height,width=struct.unpack('4H',fcntl.ioctl(fd,

                    struct.pack('4H',0,0,0,0)))[:2]
                os.close(fd)
            except:
