To Do

  • Fix grammar issues of PyYAML 3000 according to the discussion on YAML-core and IRC.
  • Write an example program (yaml-highlight) for PyYAML. It should insert tags at the beginning and the end of each token and parser event and use YAML for configuration.
  • Emitter.
  • Release PyYAML 3000.
  • Write a simple "canonical" YAML parser and a paper explaining the method.
  • libyaml3000 (SoC proposal).
  • support for yaml bytecode.

YAML mailling list

There is no specific PyYAML mailling list, there is a general  yaml mailling list on sourceforge.
