Output does not always end in newline

[dries007]

I've noticed that the output of this tool doesn't always end in a newline.

This has various annoying side effects, such as leaving the shell prompt behind the error message, causing extra diff lines in case the output files are added to git, but also the last line not showing up in some tools that parse newline delimited lines.

Examples:

user@host:/project$ hatch run pip-licenses --allow-only "GPL"
license Apache Software License not in allow-only licenses was found for package trove-classifiers:2023.8.7user@host:/project$ 

user@host:/project$ hatch run pip-licenses --format=markdown --output-file=licenses.md
created path: licenses.md
user@host:/project$ cat licenses.md 
| Name               | Version   | License                              |
|--------------------|-----------|--------------------------------------|
...
| zipp               | 3.16.2    | MIT License                          |user@host:/project$ 

This is generally considered bad behaviour and while it's not as big of an issue as it once was, I'd still like to see it fixed :).

@dries007 Thanks for the very detailed report. Your suggestion is reasonable.

Both cases appear to require ad-hoc solutions. I think we can provide a message modification when not found by --allow-only prior to the output file.

pip-licenses 4.3.3 has been released. https://pypi.org/project/pip-licenses/4.3.3/

It would be great if you could check the behavior in your environment and report back to us.

$ pip install -U "pip-licenses==4.3.3"
