v0.1.0

Initial release of the LODE language and lodec compiler.

Features

  • Schema definition format (.lode files)
  • Vein binary encoding/decoding
  • Four primitive types: string, bool, string[], map<string,string>
  • Deterministic SHA-256 fingerprinting with canonicalization
  • Verification (decode + fingerprint + compare)
  • lodec CLI with compile, decode, fingerprint, verify, diff commands
  • Forward compatibility (unknown fields skipped by decoder)

API

// Core functions
compile(source, schema): Uint8Array
decode(vein, schema): Record<string, any>
fingerprint(obj): string
verify(vein, hash, schema): boolean
loadLode(pathOrObj): LodeSchema

Wire Format

  • Magic bytes: 0x4C44 (“LD”)
  • Header: 4 bytes (magic + version + count)
  • Fields: id(1) + tag(1) + length(2) + data(N)
  • Byte order: big-endian

Roadmap
