I know that vim lets me do things like
$ ls | vim -
where it will read the data from stdin, but then take over the screen
TUI curses-style, and interact directly with the keyboard input
without being limited to input from stdin.
I've played around with something like
import sys
import curses
d = list(sys.stdin) # read/process/store it
def main(stdscr):
stdscr.clear()
for i, s in enumerate(d):
stdscr.addstr(i, 1, s.strip())
stdscr.refresh()
stdscr.getkey()
curses.wrapper(main)
but it complains when I run it with
$ seq 10 | python myprog.py
...
_curses.error: no input
I've tried adding (after the imports)
tty = open('/dev/tty', 'r+b')
curses.setupterm(fd=tty.fileno())
to coerce it, but it doesn't seem to do anything fruitful.
Any advice for how to go about replicating this vim-like behavior in
Python?
Thanks!
