Quick example of ncurses in Python!

cs.py

#!/usr/bin/env python

import curses
import curses.textpad
import time

stdscr = curses.initscr()

#curses.noecho()
#curses.echo()


begin_x = 20
begin_y = 7
height = 5
width = 40
win = curses.newwin(height, width, begin_y, begin_x)
tb = curses.textpad.Textbox(win)
text = tb.edit()
curses.addstr(4,1,text.encode('utf_8'))

#hw = "Hello world!"
#while 1:
#    c = stdscr.getch()
#    if c == ord('p'): 
#    elif c == ord('q'): break # Exit the while()
#    elif c == curses.KEY_HOME: x = y = 0

curses.endwin()

I like it without wrapper() - makes it easier to type into command-line python.

D'oh! why did I think that work work??? :-)

To get out, I just hit ^C and then pasted in the endwin() call

Thanks so much ;)

If your terminal gets completely hosed, you can usually run "tset" which means Terminal reSET.

How you can avoid keyboard interrupt problems: catch it, and reset the curses variables.

def reset(screen):
    curses.nocbreak()
    screen.keypad(0)
    curses.echo()
    curses.endwin()
try:
    #your code
    #if it terminates, call `reset(screen)` here too.
except KeyboardInterrupt:
    reset(screen)
    exit()

if c == ord('p'): print hw
?

Can someone explains me the usage of curses.wrapper()? It looks pretty simple.

Quick tip, if you exit without cleaning up and your terminal is in a wonky state, just run stty sane and it'll be good as new 😀

When I try to use the curses. I use UBUNTU and the code returns this error:
Traceback (most recent call last):
File "/home/andre/Desktop/Python - Programas/exemplo curses.py", line 4, in
stdscr = curses.initscr()
File "/usr/lib/python3.6/curses/init.py", line 30, in initscr
fd=_sys.stdout.fileno())
_curses.error: setupterm: could not find terminal

Someone knows why this occurs?
