This mod adds a merging feature for json files which are normally of the type "last man wins", such as advancements, recipes, loot tables, and the new worldgen in 1.16.2 which was the main reason I originally made a forge PR for.

 

The merging can be enabled by specifying a custom element in the json file, "_jm_combine", which contains information teaching JsonMerge how to combine the information with the previous JSON structure. See the source repository for more details and examples.

 

Actions that can be performed through the combining system: OVERWRITE, COMBINE, ZIP, APPEND, INSERT, DELETE. The valid actions in each context (objects, arrays, ...) are described int he source repository readme file.

 

Can I use this in <X>?

Yes. Unless <X>'s license is incompatible with this mod's, which is unlikely.
