3.8.0

[wwkimball]

Enhancements:

• The yaml-set and yaml-merge command-line tools now support a new option:
  --json-indent/-J. This applies only to JSON output. By default, JSON
  documents are written/printed as single-line documents. This new option
  enables users to vertically expand JSON output with a specified indentation
  size for nest levels.
• Additional *YAMLPathExceptions have been added to increase the specificity of
  various error conditions. You do not need to change any of your code as a
  result of this change; all new exceptions are subclasses of the original
  YAMLPathException. The new exceptions include:
  • UnmatchedYAMLPathException: No matching nodes
  • DuplicateKeyYAMLPathException: Duplicate key creation attempted
  • TypeMismatchYAMLPathException: Data Type mismatch
  • BadAliasYAMLPathException: Anchor/Alias/YMK error
  • NoDocumentYAMLPathException: Attempt to delete the entire document
  • RecursionYAMLPathException: Recursion nesting error
• The Processor class now enables consumers to verify whether a YAMLPath would
  resolve to at least one node in the present document. The result is a simple
  Boolean (True when the path resolves; False, otherwise). The document is not
  modified by this test. See: Processor.exists(yaml_path)

Bug Fixes:

• Pursuant to the addition of the intersection operator (&) added in 3.7.0, the
  text of one of the YAMLPathExceptions has been updated:
  Former:
  Adjoining Collectors without an operator has no meaning; try + or -
  between them, {yaml_path}
  New:
  Adjoining Collectors without an operator has no meaning; try +, -, or &
  between them, {yaml_path}
