plugin idea: tallow handling (like seedwatch)

[rh73]

Like with seedwatch, it would be nice to have a plugin which periodically checks the stocks for new sorts of tallow and forbids them in the kitchen settings. At least, until a configurable minimum number of soap bars are in the stocks/hospitals.

It would make sense for drinks as well, allowing to cook them when they are abundant, and forbid once the amount goes below a threshold.

All this (seeds, plants, drinks, tallow) is relatively similar in function, so it could/should be handled by the same plugin. Configuring the threshold(s) could be done with the lua-UI stuff; see workflow, autobutcher etc.

We have ban-cooking, which I added in 2015. It supports:

ban-cooking booze  - bans cooking of drinks
ban-cooking honey  - bans cooking of honey bee honey
ban-cooking tallow - bans cooking of tallow
ban-cooking oil    - bans cooking of oil
ban-cooking seeds  - bans cooking of plants that have seeds (tree seeds don't count)

And as of today:

ban-cooking brew   - bans cooking of plants that can be brewed into alcohol
ban-cooking mill   - bans cooking of plants that can be milled into powder
ban-cooking thread - bans cooking of plants that can be turned into thread
ban-cooking milk   - bans cooking of creature liquids that can be turned into cheese

It doesn't unban the cooking when there's a lot of that ingredient, but it might be useful for you or anyone who might stumble upon this ticket in the future.

I spent a little time today and worked out a script (based on the logic in ban-cooking) that bans/unbans brewing based on a threshold of brewed drinks, in order to encourage more variety. I can't say it's pretty, but it seems to work.
