Add gender data to populator or to data files / better gender handling

[MathyFurret]

Pokecat should have some kind of gender checking to make sure Pokemon are given the correct gender. To prevent PBR crashing all it needs is a gendered vs genderless check, but checking for male-only or female-only Pokemon would be helpful as well. Currently gender is not checked at all by pokecat itself to my knowledge.

A better default for gender would also be useful: default to null, m, f, or [m, f] depending on the gender of that species.

I believe this fits under the "error tolerance against common mistakes" requirement.

I'm all for a better default, but the PBR-crash-check in question is difficult as pokecat operates on a per-pokeset basis, so the individual processes don't have any shared context. However, exactly that check is already implemted in pokeset-ci, but that was shut down somewhen (or stopped working and noone cared, I don't exactly know).

EDIT: Or do you mean checking against each species' native "gendering"? Like checking legendaries are always genderless? That would work and sounds sensible, probably as a warning

[MathyFurret]

Yes, checking against each species' gendering

also wow I didn't know we had CI for pokesets! I'll have to check it out and maybe help rewrite it if it's needed

[Felk]

I don't think it needs a rewrite, it works fine. I remember massive warning spam being a problem, so once this pokeset-ci issue is resolved and the data adjusted accordingly, I could just start it again if I get a github token with the webhook creation permission (see the config_default.yml)
