Pygount is printing blank lines

[susumuasaga]

Windows 11
Powershell
Version 1.4.0

After I upgraded, Pygount is printing blank lines:

C:\> pygount src

I downgrade to version 1.3.0 and it is working now:

C:\> pygount src 
0       __unknown__     src     src\spark_tests.egg-info\PKG-INFO

Hm, might be related to the recent switch to rich to show the output as table. 🤔

Sadly I'm unable to investigate this with a setup similar to yours as I don't access to any Windows 11 box.

You could try to upgrade rich to the most current version:

pip install --upgrade rich

As a workaround, keep using version 1.3.0 until someone can look into this.

I'm on Windows 10 and I also get just a bunch of blank lines instead of any output. Downgrading to 1.3.0 fixes it. I don't use Powershell, just plain cmd. It's broken in both Windows Terminal app and the classical cmd.exe window.

Confirmed on Windows 10 Powershell, pygount 1.4.0
Upgrading rich did not help.

Also confirmed windows 10 pygount v1.4.0, no powershel

Rich 12.6 includes a fix for #2513 which might be related to this. In summary, running python using pythonw results in stdout being None and nothing to be rendered.

During the holidays I decided to install Python on my Windows 10 box that otherwise is exclusively used for gaming and finally track this down.

Turns out the bug shows as soon as the output for --format=sloccount is wrapped between:

with Progress(transient=True) as progress:
    try:
        ...
    finally:
        progress.stop()

Even without any progress.track().

I also noticed that using --format=sloccount on macOS in the PyCharm terminal results into weird output where tracking information is mixed with SLOC information. This might not be the case on all terminals but I found it discerning enough on this one.

So I decided to disable progress tracking for --format=sloccount for good. When writing to the terminal this should not be an issue because each file is written immediately, so there is always something going on. The only annoying case is when redirecting the output to a file. Then one can only stare at no output and wait until it's finished. So there might be a better solution but I'm not going to look into it any further.

The other writers do not have this issue because they collect all information where processing files in the background, and only once all are processed, write their findings. By then, the progress is already at 100% and not updated anymore.

This fix is included with pygount 1.5.1, which is now available from PyPI.
