NameError: name 'fcntl' is not defined

When I try to open the TUI, I get this error:

What's happening?

[ihabunek]

fcntl is not supported on windows. If you want to run toot tui you can try using WSL, although it might be overkill if that's the only thing you're using it for. It might also work in cygwin, not sure, don't have a windows box to test.

[igalic]

Is there no file handling library in Python that abstracts between platforms?

[ihabunek]

fnctl is used by urwid, which is used to build the TUI. I haven't really looked into how it could be made to work on windows.

[nausicaa-rose]

I think it would require switching from urwid to a library that supports Windows terminals as well, like asciimatics, blessed, prompt_toolkit, or textual.

If that's a direction you're willing to go, I'd be happy to work on it. I'd like to be able to use the TUI on Windows without resorting to WSL.

[ihabunek]

@wtee It is something I have considered. I tried blessed and prompt_toolkit and wasn't enamored. I liked the look of textual but it's very early in development, and needs a bit more time to mature. I'll probably be making incremental improvements to urwid variant for a little while longer. I'll check out asciimatics too, since I haven't looked at it yet.

version 0.42.0 works like a charm in cygwin on Windows 10. Installing with ' python -m pip install toot==0.42' hung installing urwid, so I just installed urwid separately.

If I knew it was going to be this easy with cygwin, I would have installed it whenI forked it last year, 60 commits ago.
