Resize the terminal with Python?

Question

I couldn\'t find anything with a quick Google search, nor anything on here, saving for this. However, it doesn\'t do the trick. So how exactly do you resize the ter

Answer 1

To change the tty/pty setting you have to use an ioctl on the stdin file descriptor.

import termios
import struct
import fcntl

def set_winsize(fd, row, col, xpix=0, ypix=0):
    winsize = struct.pack("HHHH", row, col, xpix, ypix)
    fcntl.ioctl(fd, termios.TIOCSWINSZ, winsize)

But to change the actual window size you can use terminal escape sequences, but not all terminals support or enable that feature. If you're using urxvt you can do this:

import sys
sys.stdout.write("\x1b[8;{rows};{cols}t".format(rows=32, cols=100))

But that may not work on all terminals.

Answer 2

If you install xdotool, you can change the size of the terminal window with something like this:

import subprocess
import shlex

id_cmd='xdotool getactivewindow'
resize_cmd='xdotool windowsize --usehints {id} 100 30'

proc=subprocess.Popen(shlex.split(id_cmd),stdout=subprocess.PIPE)
windowid,err=proc.communicate()
proc=subprocess.Popen(shlex.split(resize_cmd.format(id=windowid)))
proc.communicate()

PS. On Ubuntu xdotool is provided by a package of the same name.
