python3-pretty-yaml

module to produce pretty and readable YAML-serialized data (Python 3)

Description

YAML is generally nice and easy format to read if it was written by humans. PyYAML can a do fairly decent job of making stuff readable. pyaml tries to improve on that a bit, with the following tweaks:

  - Most human-friendly representation options in PyYAML get picked as
    defaults.
  - Does not dump "null" values, if possible, replacing these with just empty
    strings, which have the same meaning but reduce visual clutter and are
    easier to edit.
  - Dicts, sets, OrderedDicts, defaultdicts, namedtuples, etc are
    representable and get sorted on output (OrderedDicts and namedtuples keep
    their ordering), so that output would be as diff-friendly as possible,
    and not arbitrarily depend on Python internals.
  - It appears that at least recent PyYAML versions also do such sorting for
    Python dicts.
  - List items get indented, as they should be.
  - bytestrings that can't be auto-converted to unicode raise error, as yaml
    has no "binary bytes" (i.e. unix strings) type.
  - Attempt is made to pick more readable string representation styles,
    depending on the value.
  - "force_embed" option to avoid having &id stuff scattered all over the
    output (which might be beneficial in some cases, hence the option).
  - "&id" anchors, if used, get labels from the keys they get attached to, not
    just use meaningless enumerators.
  - "string_val_style" option to only apply to strings that are values, not
    keys.
  - Has an option to add vertical spacing (empty lines) between keys on
    different depths, to make output much more seekable.
