Don't forget the changelog! 😈

Thanks Erick, this is pretty impressive, but I'd be lying if I said I understood all of it. Can we chat about the implementation on Monday? I'd like to wrap my head around it a bit before approving.

[PietropaoloFrisoni]

I would suggest a # pragma no cover if testing is not an option right now : )

[erick-xanadu]

Can we chat about the implementation on Monday?

Definitely, I also need your help with the linter. I am not sure how to apply it 😅 In Catalyst we use a make format command. :)

[erick-xanadu]

@mudit2812 or @PietropaoloFrisoni how can I run the linter from PennyLane, in Catalyst I use make format

[PietropaoloFrisoni]

@erick-xanadu In PennyLane there's no Makefile, so I usually just format with black/isort and I check locally by running pylint on the relevant file(s)

[mudit2812]

Hey @erick-xanadu , if you use pre-commit, pylint should automatically get run every time you try to commit to pennylane. You can set it up by doing:

pip install pre-commit
pre-commit install

After this, the pre-commit hook (which includes black, pylint, and isort), should get run automatically every time you commit.

[erick-xanadu]

@PietropaoloFrisoni and/or @mudit2812 is there a way to disable codecov? I already tried no cover. 🤔

[mudit2812]

@erick-xanadu this is a good reference. Apparently using # pragma: exclude file should disable coverage for the whole file. # pragma: no cover is for single lines and closures, not files.

[erick-xanadu]

@mudit2812 , I think your link says I should modify the pyproject.toml file:

[tool.coverage.report]
exclude_also = [
    # 1. Exclude an except clause of a specific form:
    'except ValueError:\n\s*assume\(False\)',
    # 2. Comments to turn coverage on and off:
    'no cover: start(?s:.)*?no cover: stop',
    # 3. A pragma comment that excludes an entire file:
    '\A(?s:.*# pragma: exclude file.*)\Z',
]

Thanks a lot @erick-xanadu !
