[issue45870] There's no readline module on Windows Python (cmd.Cmd)

E:V:A added the comment: I would like to make the python community aware that there has recently been a renewed interest in updating and maintaining 'pyreadline', but in a new(ish) repository 'pyreadline3'. https://github.com/pyreadline3/pyreadline3 This apparently now works under Py3.10,

keeely added the comment: I'm attaching an example usage of cmd + readline to show how you can have context-specific history for sub-shells. WARNING: WRITES FILES TO CWD! In the event that someone does implement this on Windows it would be nice if this worked. That doesn't mean

keeely added the comment: Regrettably I cannot submit a PR for the docs because I value my online anonymity and Python submissions require a real name (IIRC), but my suggestion would be pretty simple. Taking as an example, for termios (https://docs.python.org/3/library/termios.html), we

Guido van Rossum added the comment: Okay, so that's all hypothetical. It looks like the status quo is not likely to change, so we should just document it. I wonder if keeely is interested in submitting a PR for the docs? -- ___ Python tracker

Guido van Rossum added the comment: AFAIK the reason command history works in cmd.py on Windows is that it's built into the terminal program. Or maybe into the operating system. Thus, the user can use line editing and history, but there is no API (in Python) to interact with these. I'm

[issue45870] There's no readline module on Windows Python (cmd.Cmd)

New submission from keeely : In the past this was worked around by installing a third-party module: https://github.com/pyreadline/pyreadline For Python 3.10, however this module doesn't work. And pyreadline doesn't seem to be maintained anymore, so it's possible it won't get fixed.
