need to bring formatters back from tablib

[Doug Hellmann]

Several useful formatters that depend on tablib were moved to a separate lib to satisfy debian packaging requirements (something to do with tablib vendoring some other library). We should revisit, and either reimplement them or just bring them back into cliff.

[Steve Baker (steve-stevebaker)]

Arguments for removing the tablib formatters:
- tablib vendors mulitple dependencies
- tablib is supposed to be for formatting tabular data, but yaml and json are not tabular formats so would be better off being implemented in cliff
- since the table formatter is already from cliff, this would leave the html formatter as the only remaining formatter. Its possible nobody is even interested in this one

    Implement a yaml formatter in cliff

    This change replaces the cliff-tablib yaml formatter with an internal
    replacement. It differs from the tablib formatter in the following ways:
    - always outputs with block formatting rather than the PyYAML default
      of deciding based on value content
    - emit_one serialises a simple dict where the column name is the key
      and the data item is the value (rather than a list of dicts with
      'Field' and 'Value' keys)
    - emit_one preserves column order by printing a single-item dict for
      each column_name

    The cliff release which contains this change will need a corresponding
    cliff-tablib release which removes the yaml formatter from its setup.py
    entry_points.

    Implement a json formatter in cliff

    This change replaces the cliff-tablib json formatter with an internal
    replacement. It differs from the tablib formatter in the following ways:
    - by default outputs with an indent of 2 spaces. The --noindent formatting
      argument outputs with no indentation, to save space or to pipe to tools
      which can't handle multi-line input.
    - emit_one serialises a simple dict where the column name is the key
    and the data item is the value (rather than a list of dicts with
    'Field' and 'Value' keys)

    The cliff release which contains this change will need a corresponding

Assuming that nobody cares about the html formatter, this could be marked FixedReleased in 1.15.0

[Steve Martinelli (stevemar)]

This was released a long time ago.
