I've recently installed the windows-curses
module on my machine, via py -m pip install windows-curses
run in an elevated command prompt.
I wrote the following code to test if it was working correctly. If it runs correctly, it should print the string test
to the console. However, nothing happens - i.e the terminal remains blank, with no characters displayed.
#initialise curses
import curses
stdscr=curses.initscr()
curses.noecho()
curses.cbreak()
stdscr.keypad(True)
#write text
stdscr.addstr(0,0,'test')
#loop program so the terminal does not close
while 1:
pass
I've tried putting the addstr
call inside the while loop, as well as using the wrapper
, but neither resolved the issue.
What's going on, and how can I resolve this issue? Thanks in advance!
You have to refresh the screen. Curses does a physical screen update when you ask for input, e.g. with window.getch()
or call window.refresh()
directly.
Try this snippet:
#write text
stdscr.addstr(0, 0, 'test')
#loop program so the terminal does not close
while 1:
c = stdscr.getch()
key = curses.keyname(c)
if key == b'q':
break
else:
stdscr.addstr(1, 0, repr(key))
curses.endwin()
