Windows Support?

[scruffaluff]

autohooks/terminal.py depends on the curses package, which I believe is not supported on Windows. When I run the command poetry run autohooks activate, I receive the error ModuleNotFoundError: No module named _curses. Am I suppose to use a different command to activate the git hooks on Windows?

Internally autohooks uses blessings to provide colorization of the console output. After looking at it I don't think it supports Windows :-/

Personally I am not able to write any code for Windows because my knowledge about it is very small. And I also don't have access to any Windows system.

But this doesn't mean autohooks shouldn't get support for Windows. I am only relying on PRs from external contributors.

As far as I know curses should be at least importable at windows. Could you paste the whole taceback? Maybe it is already possible to support windows by using https://github.com/tartley/colorama

FYI, I am using powershell on Windows with poetry and pyenv. I haven’t tried colorama, but here is the trace back:

Could you do me a favor and just run import curses in a python shell?

[scruffaluff]

Sure. Here is the trace back:

ok. I've done some research. Python in windows doesn't support curses. It seems you need to install an additional library to get it working https://www.lfd.uci.edu/~gohlke/pythonlibs/#curses

From https://docs.python.org/3/howto/curses.html#curses-howto

The Windows version of Python doesn’t include the curses module. A ported version called UniCurses is available. You could also try the Console module written by Fredrik Lundh, which doesn’t use the same API as curses but provides cursor-addressable text output and full support for mouse and keyboard input.

Hmm maybe blessings doesn't work at all on windows https://github.com/erikrose/blessings/issues/21

(FWIW, blessed, a fork of blessings, does work on windows)
