stockpile presets (?) for butcherable races only

[ab9rf]

Now that corpse stockpiles are filterable, it would be useful to have some way to quickly create a stockpile that only accepts butcherable corpses (or at least corpses for butcherable races).

Note that this can't exactly be a static preset because which races are butcherable depends on the fortress entity's ethics.

[myk002]

what is the code for determining if the race is butcherable? And are there other examples of properties that we might want to filter on?

I'd find these useful as presets:

• Caged creatures that are trainable
• Caged creatures that are butcherable
• Any other caged creatures (eg for pitting)
• Corpses/bodyparts that can be butchered (ie not intelligent and not too small (weasels etc))
• Corpses/bodyparts that cannot be butchered
• Seeds that are plantable in Temperate biomes
• Seeds that are plantable in Tropical biomes
• Seeds that are plantable in Temperate and Tropical biomes
• Seeds that are plantable Underground
• Seeds that can only be eaten/cooked (acorns etc)
• Seed that are useless (inedible tree seeds)
• Plant products that can be brewed
• Plant products that can be processed (perhaps split by method/dye/flour etc)
• Plant products that can only be cooked
