I have the following basic curses implementation in Python3.
#!/usr/bin/env python3
import curses
import time
from curses import wrapper
stdscr = curses.initscr() # required
curses.noecho() # don't show keyboard input
curses.cbreak() # don't require enter to send input
stdscr.keypad(True)
def main(stdscr):
# curses.newwin(5, 10, 7, 20)
stdscr.addstr("SUMMON SHOGGOTHS")
stdscr.addstr(20, 30, "Razzmatazz")
stdscr.refresh()
time.sleep(3)
wrapper(main)
# Unwind
curses.nocbreak()
stdscr.keypad(False)
curses.echo()
curses.endwin()
Pretty much everything happens that I would expect: Shoggoths are Summoned and Razzes are matazzed, however when I enter git status my lines breaks are broken.
Doing a diff between stty -a before and after showed:
5c5
< iflags: -istrip icrnl -inlcr -igncr ixon -ixoff ixany imaxbel -iutf8
---
> iflags: -istrip -icrnl -inlcr -igncr ixon -ixoff ixany imaxbel -iutf8
7c7
< oflags: opost onlcr -oxtabs -onocr -onlret
---
> oflags: opost -onlcr -oxtabs -onocr -onlret
After investigating these options, I found that issuing stty onlcr fixes the terminal. I'm surprised, however, because I thought that curses.endwin() would have reset me:
De-initialize the library, and return terminal to normal status.
I thought it might be an issue in iTerm2, so then I tried with Terminal.app. This produced the same behavior.
I'm stumped is there some other re-set technique? I saw in C-based implementations the stty data are often saved into a struct for restoration...that might be an avenue of pursuit.
Thanks for any help!
