Add Windows support

[wnhrt]

Known issues:

• can only handle single char input (no arrows, ctrl-KEY or alt-KEY)
• does not resize on size change of window
• no support for variable length unicode symbols

Thanks for the great job to fix #5. 👍
I think I will first separate the existing code into a terminal dependent (→ backend) and independent part to avoid all the if/else blocks and perhaps I can find some solutions to the remaining limitations. Would be great to have arrow key support, since I don't think that everyone is used to vi motions. 😊

No problem :) I hope this helps to adapt the code for Windows.
Separating the code sounds like a very good idea. Looking forward to your implementations.

Regarding arrow support, this is the best I could came up with, without using external dependencies. But still no modifier keys.
I tried to implement it with Windows legacy code from kernel32.dll and user32.dll, but had no success.

Heureka! Here are two possible solutions, which both use the Windows API:

• input
• resize event (historically CMD.exe only reacts on horizontal change, 'Windows Terminal' on both axes)

any updates on this?

Not yet. I started to work on integrating the changes, but switched to other tasks...
