YAML is a flexible, human readable file format that is ideal for storing object trees. YAML stands for “YAML Ain't Markup Language”. It is easier to read (by humans) than JSON, and can contain richer meta data. It is far nicer than XML.
It will be nice if envgen can take a yaml file as input to create complex HPCC topology environment.xml instead of individual parameters.
YAML may also help configure other components with HPCC Platform.
It is free to use.
