Contains one function, wrapper(), which runs another function which
4
should be the rest of your curses-based application. If the
5
application raises an exception, wrapper() will restore the terminal
6
to a sane state so you can read the resulting traceback.

def wrapper(func, *args, **kwds):
13
"""Wrapper function that initializes curses and calls another function,
14
restoring normal keyboard/screen behavior on error.

The callable object 'func' is then passed the main window 'stdscr'
16
as its first argument, followed by any other arguments passed to

# Turn off echoing of keys, and enter cbreak mode,
26
# where no buffering is performed on keyboard input
30
# In keypad mode, escape sequences for special keys
31
# (like the cursor keys) will be interpreted and
32
# a special value like curses.KEY_LEFT will be returned
35
# Start color, too. Harmless if the terminal doesn't have
36
# color; user can test with has_color() later on. The try/catch
37
# works around a minor bit of over-conscientiousness in the curses
38
# module -- the error return from C start_color() is ignorable.
