What would it take to set up a custom process, probably on the Farmers Workshop, to extract seeds directly from plants?
I have absolutely zero experience in modding DF, so any hints on where to start looking (or if you're feeling generous, a complete solution) would be very appreciated.
Basically I would like to extract seeds directly from plants, destroying the plant in the process, without having to muck about with barrels and such (like brewing booze requires).

Edit every plant that has seeds and add the following to the STRUCTURAL material:

Code: [Select]

[MATERIAL_REACTION_PRODUCT:SEED_MAT:LOCAL_PLANT_MAT:SEED]

Then add the following to reaction_other.txt:

Code: [Select]

[REACTION:EXTRACT_SEEDS]
[NAME:extract seeds]
[BUILDING:KITCHEN:CUSTOM_S]
[REAGENT:A:1:PLANT:NONE:NONE:NONE][UNROTTEN]
[HAS_MATERIAL_REACTION_PRODUCT:SEED_MAT]
[PRODUCT:100:3:SEEDS:NONE:GET_MATERIAL_FROM_REAGENT:A:SEED_MAT]
[SKILL:PROCESSPLANTS]

Finally, edit entity_default.txt and allow your civilization to perform the EXTRACT_SEEDS reaction, then generate a new world.

As a note, this one uses the kitchen because it's not possible to add custom reactions to the farmer's workshop.
