[issue43715] curses inch() and scrbkgd() documentation ommissions
New submission from Peter J. Farley III : The documentation for the result values of curses functions inch() and scrbkgd() or how to use those result values are omitted entirely. Documentation should at least describe how to use the result values of these functions without necessarily describing the actual format of the results, which do differ depending on the implementation of curses being used. A suggestion for the documentation change is attached. A separate issue will be filed questioning the need to shift the pair number result of the curses.pair_number() function in the Windows terminal environment. -- components: Extension Modules files: curses-doc-change.txt messages: 390136 nosy: pjfarleyiii priority: normal severity: normal status: open title: curses inch() and scrbkgd() documentation ommissions versions: Python 3.8, Python 3.9 Added file: https://bugs.python.org/file49930/curses-doc-change.txt ___ Python tracker <https://bugs.python.org/issue43715> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue43716] curses.pair_number() function incorrect value under Windows
New submission from Peter J. Farley III : curses.pair_number() result under Windows (console or Terminal window) value must be shifted by 16 bits to be valid to use as input to the curses.pair_content() function. If the pair number result is not shifted, the call to curses.pair_content() fails with an overflow error: Traceback (most recent call last): File "C:\Users\MyUser\test\curses-color.py", line 126, in curses.wrapper(main) File "C:\Python38\lib\curses\__init__.py", line 105, in wrapper return func(stdscr, *args, **kwds) File "C:\Users\MyUser\test\curses-color.py", line 72, in main fg, bg = curses.pair_content (pair) OverflowError: signed short integer is greater than maximum The attached curses program demonstrates the correct functioning using the pair value shift under Windows. Comment out the "if" and shift lines to reproduce the overflow error.

Peter J. Farley III added the comment: Sorry, this was not meant as a patch. I have no experience with git or pulls and would not know where to start to do as you have asked. The text I provided was intended as model text for the python documentation maintainer to type into whatever piece of python is used to describe those two functions. If I knew where to pull a source archive or zip and knew the place or source member where that documentation is stored, I could generate a "diff -u" style of patch, but that is the limit of my skill in that area.
