[Compare v0.4.1...v0.4.2(https://github.com/dry-rb/dry-logic/compare/v0.4.1...v0.4.2)

v0.4.1 2017-01-23

Compare v0.4.0...v0.4.1

v0.4.0 2016-09-21

This is a partial rewrite focused on internal clean up and major performance improvements. This is also the beginning of the work to make this library first-class rather than "just" a rule backend for dry-validation and dry-types.

Added

  • Rule#[] which applies a rule and always returns true or false (solnic)
  • Rule#bind which returns a rule with its predicate bound to a given object (solnic)
  • Rule#eval_args which evaluates unbound-methods-args in the context of a given object (solnic)
  • Logic.Rule builder function (solnic)
  • Nice #inspect on rules and operation objects (solnic)

Changed

  • [BRAEKING] New result API (solnic)
  • [BREAKING] Predicate is now Rule::Predicate (solnic)
  • [BREAKING] Rule::Conjunction is now Operation::And (solnic)
  • [BREAKING] Rule::Disjunction is now Operation::Or (solnic)
  • [BREAKING] Rule::ExlusiveDisjunction is now Operation::Xor (solnic)
  • [BREAKING] Rule::Implication is now Operation::Implication (solnic)
  • [BREAKING] Rule::Set is now Operation::Set (solnic)
  • [BREAKING] Rule::Each is now Operation::Each (solnic)
  • [BREAKING] Rule.new accepts a predicate function as its first arg now (solnic)
  • [BREAKING] Rule#name is now Rule#id (solnic)
  • Rule#parameters is public now (solnic)

Compare v0.3.0...v0.4.0

v0.3.0 2016-07-01

Added

  • :type? predicate imported from dry-types (solnic)
  • Rule#curry interface (solnic)

Changed

  • Predicates AST now includes information about args (names & possible values) (fran-worley + solnic)
  • Predicates raise errors when they are called with invalid arity (fran-worley + solnic)
  • Rules no longer evaluate input twice when building result objects (solnic)

Compare v0.2.3...v0.3.0

v0.2.3 2016-05-11

Added

  • not_eql?, includes?, excludes? predicates (fran-worley)

Changed

  • Renamed inclusion? to included_in? and deprecated inclusion? (fran-worley)
  • Renamed exclusion? to excluded_from? and deprecated exclusion? (fran-worley)

Compare v0.2.2...v0.2.3

v0.2.2 2016-03-30

Added

  • number?, odd?, even? predicates (fran-worley)

Compare v0.2.1...v0.2.2

v0.2.1 2016-03-20

Fixed

  • Result AST for Rule::Each correctly maps elements with eql inputs (solnic)

v0.2.0 2016-03-11

Changed

  • Entire AST has been redefined (solnic)

Compare v0.1.4...v0.2.0

v0.1.4 2016-01-27

Added

  • Support for hash-names in Check and Result which can properly resolve input from nested results (solnic)

Compare v0.1.3...v0.1.4

v0.1.3 2016-01-27

Added

  • Support for resolving input from Rule::Result (solnic)

Changed

  • Check and Result carry original input(s) (solnic)

Compare v0.1.2...v0.1.3

v0.1.2 2016-01-19

Fixed

  • xor returns wrapped results when used against another result-rule (solnic)

Compare v0.1.1...v0.1.2

v0.1.1 2016-01-18

Added

  • Rule::Attr which can be applied to a data object with attr readers (SunnyMagadan)
  • Rule::Result which can be applied to a result object (solnic)
  • true? and false? predicates (solnic)
