Merge array increment by deep key

In pins 5

base array array required
array to merge into
from array array required
array to merge from
deep key value
the key to be merged, if none given, the main array wil be merged
compare key value required
the keys to be compared, based on the comparision, these objects are merged
increment keys array
Keys to increment, within the array being merged. For example quantity

Out pins 1

merged array array

Merges base_array then merge_from into one array deduplicated on the string value of compare_key: the first occurrence is kept and later occurrences shallow-merge over it, their fields overwriting, EXCEPT the increment_keys fields which are summed numerically. With deep_key set, items are drawn from the array at that path inside each element. Non-array base outputs [] plus error BASE_ARRAY_IS_INVALID; empty compare_key outputs [] plus MISSING_COMPARE_KEY.

merge increment deep key

merge deep

A typical wiring for by compare key: with values feeds the base_array pin; with values feeds the merge_from pin; value feeds the compare_key pin; the merged_array out pin feeds length.
