Method searchIndexableWithPathPrefixes

viper.go:517–540

searchIndexableWithPathPrefixes recursively searches for a value for path in source map/slice. While searchMap() considers each path element as a single map key or slice index, this function searches for, and prioritizes, merged path elements. e.g., if in the source, "foo" is defined with a sub-key

(source any, path []string)

//
// Note: This assumes that the path entries and map keys are lower cased.
func (v *Viper) searchIndexableWithPathPrefixes(source any, path []string) any {
	if len(path) == 0 {
		return source
	}

	// search for path prefixes, starting from the longest one
	for i := len(path); i > 0; i-- {
		prefixKey := strings.ToLower(strings.Join(path[0:i], v.keyDelim))

		var val any
		switch sourceIndexable := source.(type) {
		case []any:
			val = v.searchSliceWithPathPrefixes(sourceIndexable, prefixKey, i, path)
		case map[string]any:
			val = v.searchMapWithPathPrefixes(sourceIndexable, prefixKey, i, path)
		}
		if val != nil {
			return val
		}
	}

	// not found
	return nil
}

// searchSliceWithPathPrefixes searches for a value for path in sourceSlice
