As I know squat about the curses module is this a time when a bug
report could be put into the docs to clarify things, or do you have to
know something about curses before you try using the Python wrapper?
Well, both.
The Python curses module is mostly a thin shim around the curses(3) C
library. So the real semantics come from that; the Python module doco
test closely resembles the text from the curses(3) manual entry (what
you get from the "man 3 curses" command).
The curses(3) manual entry (well, ncurses on my Mac here) says:
The ncurses library includes facilities for responding to window resizing
events, e.g., when running in an xterm. See the resizeterm(3X) and
wresize(3X) manual pages for details. In addition, the library may be
configured with a SIGWINCH handler.
and resizeterm(3) says in part:
resizeterm
The function resizeterm resizes the standard and current windows to
the specified dimensions, and adjusts other bookkeeping data used by
the ncurses library that record the window dimensions such as the
LINES and COLS variables.
However, since people using the Python module might reasonably be
expected to know less than those using the C library directly it would
be useful to make it more clear that resizeterm() is essentailly "tell
curses the terminal size" function, not a "make the terminal a specific
size" function, and that because curses normally notices changes
automatically then it is uncommon to need to call resizeterm().
