Unable to set workflow quantity of quarry bush leaves

[drakesiard]

Setup: Vanilla df 0.40.24 and dfhack 0.40.24-r1
To reproduce:

1. Create a "Process plant to bag" task at a Farmer's Workshop.
2. Use the workshop-job plugin to change the material to "quarry bush plant"
3. Try to set a range constraint using the workflow plugin
   Note that quarry bush leaves are not in the list of possible outputs.

I assume this was broken by the plant part rewrite.

This is because workflow does not understand GET_ITEM_DATA_FROM_REAGENT token used in the reaction. No idea if it's fixable or not, but changing the reaction provides a workaround (assuming you only want to process quarry bushes to bags and not any other future processable plants):

more specifically, the item type selection dialog used by workflow is implemented in the materials plugin, which uses dfhack.items.getSubtypeCount() to find the number of subtypes for a given type of item. however the function returns -1 for the type PLANT_GROWTH.

afaik to find the actual subtypes for the plant_growths one has to browse through the complete list of plant raws. if the plant material is known finding the growth is simple, but the item type dialog doesnt know about materials.
