## Minutes

* P-rad format:
* Code: https://github.com/phyzicist/pradformat/tree/main/Python
* Docs: https://scott.cikeys.com/prad/overview/
* came out of a workshop and very early in development
* reading and writing to HDF5 geared for proton radiography
* 3 part output:
* initial condition for particles
* field grid
* output radiograph
* Is the package too young to become a dependency?
* not just the package; metadata standard
* Smilar to openPMD: https://www.openpmd.org/#/start
* Would openPMD be a better option?
* sounds like a subset, actually!
* does not, IIRC, support the radiograph output
* openPMD is more of metadata scheme
* documentation uses HDF5 files as examples
* version 0.2;
* https://join.slack.com/t/openpmd/shared_invite/zt-q7rtw6s3-lDca4ckkEgnF9xsboVjnkA
* Adopting dependencies
* probably a case-by-case basis
* e.g. Dominik needs https://github.com/RemDelaporteMathurin/plasma-boundaries for neoclassics
* let's not be too hasty in adopting new code dependencies; let's be enthusiastic adopters of new metadata standards
* Automodapi needs review
* code doesn't need that much strict review; docs would
* Integer charge to charge number?
* `FutureWarning`: Will be removed in version 0.9
* Astropy deprecation decorator: https://docs.astropy.org/en/stable/api/astropy.utils.decorators.deprecated.html
* takes https://docs.astropy.org/en/stable/_modules/astropy/utils/exceptions.html#AstropyDeprecationWarning by default; flexible enough to hot swap for a PlasmaPyDeprecationWarning

class AbstractParticle:
    @property
    # @deprecated()
    def interger_charge(self):
        warn("blah blah", RemoveIn09)
        return self.charge_number
    
    @property
    def charge_number(self):
        return self._charge_number


@pytest.mark.skipif(plasmapy.version > (0, 7))
def test_dependent_on_version(): # but doesn't catch anything on dev
# needs cleverness that I think can be arranged


# utils:

class PlasmaPyFutureWarning(FutureWarning):
    ...
    
deprecated = partial(astropy.deprecated, warningtype = PlasmaPyFutureWarning, pending=False)
"""
Thin wrapper on top of `astropy.utils.decorators.deprecated`.

* https://stackoverflow.com/questions/55377831/difference-between-deprecationwarning-pendingdeprecationwarning-and-futurewarni
* [Old issue on PlasmaPy `deprecated` decorator](https://github.com/PlasmaPy/PlasmaPy/issues/945)
* could close it with #1126

* Automodapi has subtle difference between ours and astropy's
* astropy creates TWO stub files for each function (plasmapy.formulary and plasmapy.formulary.parameters)
* we link, instead, for everything that's not a variable
* those have no module dunder
* [as I understand it:] canonical path is original path, rather than the reimport path
* always use the long name to where *thing* is originally defined
* Paschen:
* Nick's meeting with Christoph
* 1 on 1 so as to avoid an overabundance of cooks
* has docstrings! :tada:
* Vaccine after-effects suck, but not as much as SARS-COV-2 does!
