README

mergemap

mergemap is a Go library to recursively merge JSON maps.

Behavior

mergemap performs a simple merge of the src map into the dst map. That is, it takes the src value when there is a key conflict.

The only special behavior is when the conflicting key represents a map in both src and dst. Then, mergemap recursively descends into both maps, repeating the same logic. The max recursion depth is set by mergemap.MaxDepth.

Usage

var m1, m2 map[string]interface{}
json.Unmarshal(buf1, &m1)
json.Unmarshal(buf2, &m2)

merged := mergemap.Merge(m1, m2)

See the test file for some pretty straightforward examples.

Functions

func Merge

func Merge(dst, src map[string]interface{}) map[string]interface{}

Merge recursively merges the src and dst maps. Key conflicts are resolved by preferring src, or recursively descending, if both src and dst are maps.
