kiba-common

This is a maintenance release with code clean-up.

• Support for Kiba 4
• Breaking: Drop support for Ruby < 2.5
• Breaking: Require Kiba 3+
• StandardRB has been added for formatting & linting the codebase.

• Support for Ruby 2.7+ (affects CSV source and destination)
• Breaking: show_me! is now compatible with both awesome_print and its modern replacement amazing_print. You will have to require the one you want to use in your code from now on.
• Breaking: SourceTransformAdapter has been removed due to complexities with Ruby 2.7+ keyword arguments. The suggested replacement is to use Enumerator and EnumerableExploder like this:

# before
transform SourceTransformAdapter

# after
transform do |klass, args|
  Enumerator.new do |y|
    # NOTE: you may have to use double-splat (**) here instead
    # if you provide keyword arguments, or other variants
    klass.new(*args).each do |r|
      y << r
    end
  end
end

transform Kiba::Common::Transforms::EnumerableExploder

• Kiba ETL v3 compatibility
• New: Kiba::Common::Destinations::Lambda lets you write block-form destinations (handy for one-off scripts).

0.9.0

• New: Kiba::Common::Sources::CSV provides a basic CSV source for simple needs.
