YAML BasicsFor Ansible, nearly every YAML file starts with a list.Each item in the list is a list of key/value pairs, commonlycalled a “hash” or a “dictionary”. So, we need to know howto write lists and dictionaries in YAML.There’s another small quirk to YAML. All YAML files (regardless of their association with Ansible or not) can optionallybegin with - and end with. This is part of the YAML format and indicates the start and end of a document.All members of a list are lines beginning at the same indentation level starting with a '- ' (a dash and a space).

Basic round trip of parsing YAML to Python objects, modifying and generating YAML. You can change this default indentation by e.g. Using yaml.indent.

It is C-based.Parsers for YAML subsetsLuckily, you may not need the full YAML spec. These libraries can parse only the sweetest parts of YAML spec that you may reuse in your configs.Unfortunately, there doesn't seem to be any Python code that parses YAML subset - pretty much every lib uses PyYAML.
But still it worth to list honorable mentions that may be modified to build mininal parsers:.rsolnite -.kivy - andYAML (last edited 2017-08-07 19:45:34 by ).
