Compare v0.3.0...v0.3.1

v0.3.0 2015-07-12

This release deprecates a couple of APIs and changes the way functions can be accessed. The global Transproc() function registry is now deprecated and you should define your own function registry via extend Transproc::Registry and its import interface. See API docs for the details.

Proper deprecation warnings will appear as this is still a backward-compatible release, however, please update to the new API as the global registry will be gone in 1.0.0.

Added

• HashTransformations.eval_values which evaluates callable values in a hash recursively (solnic)
• HashTransformations.deep_symbolize_keys which, surprise surprise, symbolizes keys in a hash, recursively (solnic)
• Shared examples :transforming_immutable_data and :mutating_input_data to specify transformations in RSpec (nepalez)

Changed

• Transproc::Registry now uses singleton methods that can be imported from arbitrary modules via import interface (nepalez)
• Updated all built-in modules to the new registry API (nepalez + solnic)
• Transproc() has been deprecated (solnic)
• Transproc::Helper has been deprecated (solnic)

Compare v0.2.4...v0.3.0

v0.2.4 2015-06-20

Added

• Transproc::Registry extension for registering reusable functions within modules (nepalez)
• :recursion recurse over an enumerable (AMHOL)

Changed

• :group, :nest, and :wrap support adding new data to existing groups/wraps (nepalez)
• Transproc::MalformedInputError includes original backtrace now (solnic)

Compare v0.2.3...v0.2.4

• :ungroup is an inverse array transormation with respect to the :group (nepalez)
• :insert_key (and :insert_key!) is the partial inversion of :extract_key. The method converts array of values into array of tuples with given key (nepalez)
• :add_keys (and :add_keys!) adds missing keys to all tuples in array (nepalez)

Fixed

• Warning about circular requires is gone now (splattael)

Compare v0.2.2...v0.2.3
