13795 :: nimhuml – A Nim parser and serializer for HUML (Human-Oriented Markup Language)

  Hi everyone,

  I've been working on nimhuml, a Nim implementation of the HUML parser and serializer.

  What is HUML?

  HUML (huml.io) is a serialization language for documents, datasets, and config files created by Kailash Nadh. It looks like YAML but is intentionally stricter, one canonical way to write everything, no indentation ambiguity, no silent footguns.

  What does nimhuml do?

  • Parse HUML strings and files into JsonNode
  • Serialize JsonNode back to HUML
  • Full HUML v0.2.0 spec support: scalars, inline and multiline dicts/lists, multiline strings, comments, hex/octal/binary numbers, version directives

  Links:

  • GitHub: https://github.com/w3Abhishek/nimhuml
  • HUML spec: https://huml.io

  This is still early (v0.2.0) so feedback, bug reports, and contributions are very welcome. Would love to hear from anyone who's been looking for a cleaner alternative to YAML in their Nim projects.

  It's unclear why it parses into a JsonNode. I think it would be much better to create something like a HumlNode instead

  Oh an indentational serialization / markup lang, thats interesting and also befitting the python and nim community. With which data-langs is Huml isomorph (i mean like translatable without loosing info)?
