Please indicate that Windows is not supported #376

excalamus · 2020-02-17T18:35:19Z

According to #257, Windows is not supported. I had mistakenly assumed it was since I saw Azure and DOS references. It doesn't seem like system requirements are indicated anywhere on the README.

I put a mention under "Features" for lack of a better place.

Respectfully,
Matt

https://en.wikipedia.org/wiki/Windows_Terminal claims that Windows Terminal (the new one, not the old "Command Prompt" thing) supports ANSI sequences now, so that might actually work. Could you try?

I think it also works under WSL.

Upgraded to Windows 10 1909 and installed Windows_Terminal. Same error:

I notice now that pudb only supports up to Python 3.5 (from PyPi). That might be worth putting in the README, too.

For kicks I tried it with Python 3.4:

Thanks for trying and relaying the results.

Could you try the curses display? (Edit $HOME/.config/pudb/pudb.cfg to set display to curses.

The 3.x version specifics are outdated nonsense. I routinely use pudb with 3.7 and 3.8. 411614c gets rid of them.

asmeurer · 2020-02-17T22:01:51Z

I would also note here that the issue is with the urwid library, not pudb. I believe PuDB should work just fine with Windows once urwid supports it.

Does import curses succeed? It looks like you're still on the raw display:

  File "C:\projects\tester\py34\lib\site-packages\urwid\raw_display.py", line 92, in __init__
    fcntl.fcntl(self._resize_pipe_rd, fcntl.F_SETFL, os.O_NONBLOCK)

As far as I know, I'm using the preview terminal:

No go on the import curses:

According to https://docs.python.org/3/howto/curses.html, the Windows build of Python doesn't include curses. It suggests you could use https://pypi.org/project/UniCurses/ instead.

UniCurses fails to install through pip. Last update seems to be from 2014.
