Project Description


LCONF stands for L(ight) CONF(iguration) a light - human-friendly, simple readable data serialization format for dynamic configuration.



  • in many situations LCONF is a suitable replacement for YAML
  • LCONF can be used to replace JSON in many cases


  • LCONF python library is much faster than PyYAML 3.11
  • LCONF python library emits much faster than the python included json (c extension) defaults
  • LCONF python library parses a little bit faster than the python included json (c extension) using an OrderedDict
  • LCONF python library parses still much slower than the python included json (c extension) defaults
