Failure on Windows 10

pip install reports success:

But when I try to run the first example:
python -m pudb.run binsearch.py

I see:

Sorry, I don't think Urwid (the widget library used by pudb) works on Windows.

[inducer]

Cygwin might be an option. At any rate--if and when Urwid does start supporting Windows, pudb should (famous last words) work there, too.

At any rate, thanks for the report.

I'm curious if you can make it work on the Linux subsystem. I don't have Windows, otherwise I would play around with this.

[BruceEckel]

Trying that now.

If you can get it to work on Cygwin or the Linux subsystem or some other way, please report back. Would love to have some docs for it if it can be made to work.

[BruceEckel]

Works on Windows 10 Linux subsystem, at least for Python 2.7. You have to explicitly install pip if it's not there; it doesn't come as part of the Python installation. Other than that the basic instructions seem to do the trick.

Does the Linux subsystem require using a separate Python from the Windows one?

[BruceEckel]

If I remember correctly it comes with its own Python. This idea is reinforced because no amount of apt-get remove could get rid of all the Pythons. Plus I know Ubuntu uses a lot of Python internally, so that makes sense. And yes, if Python 3 is installed on Windows it doesn't show up automatically in the Ubuntu shell -- you have to apt-get it yourself.

So it's a completely different environment. I wasn't sure if you could mix and match Windows executables somehow. That's a bit limiting, as it means you'd have to get whatever you're debugging running in the Linux subsystem to use PuDB. But if it doesn't have many dependencies it's probably not that bad.

[BruceEckel]

Well, not precisely. If you install pure command-line apps in Ubuntu you can call them from DOS/Powershell as if they were native Windows programs, which is pretty amazing IMO. And for other apps you can just say "bash appname" and it runs them. But yes, as far as I can tell there's no way to call Windows programs from within Ubuntu.
