libfyaml is a feature-complete YAML 1.2 parser/emitter written in C. It passes the entire official YAML test suite and focuses on high performance with zero-copy operation.

  What's new in v0.9.4:

  • Full native Windows support (MSVC, clang-cl, Clang) - all tests pass
  • Comment handling moved out of experimental - comments can now be reliably preserved and round-tripped

  Happy to answer questions about the implementation or YAML parsing in general.
