Function stringFromMap

cli/plugins/args_extract.go:76–86

stringFromMap returns the first non-empty string value found for any of the given keys in the JSON map. Numbers and booleans are ignored — DescribeCall is for showing human-readable identifiers.

(m map[string]json.RawMessage, keys []string)

// of the given keys in the JSON map. Numbers and booleans are ignored
// — DescribeCall is for showing human-readable identifiers.
func stringFromMap(m map[string]json.RawMessage, keys []string) string {
	for _, k := range keys {
		if raw, ok := m[k]; ok {
			var s string
			if err := json.Unmarshal(raw, &s); err == nil && s != "" {
				return s
			}
		}
	}
	return ""
}

// jsonString is the shorthand used by atomic-tool plugins (@read,
// @search, @tree, @todo, …) that own the parsed JSON object directly.
