From c22abda79b7f0fbee5f0ef0e9648d52d7d483902 Mon Sep 17 00:00:00 2001 From: Shahbaz Javeed Date: Thu, 10 Dec 2015 16:50:28 -0500 Subject: * Support for bitwise operations as infix operators. Tests included. *** Individual commit messages included below *** * Preliminary support for bitwise operations as infix operators. Tests to follow. * Added bitwise xor, shift left and shift right operators * Fixed the BitwiseOr class so it uses the :| operator instead of :& * All the methods for the bitwise operators in the Arel::Math module now wrap them up in Arel::Nodes::Grouping so the operation becomes isolated like addition and subtraction * Preliminary set of tests for the new operators * Updated README with examples of bitwise operations * Added a new UnaryOperation class which is a riff on the InfixOperation class * Added tests for UnaryOperation (inspired by InfixOperation tests) * Added the bitwise not (~) operator as a UnaryOperation * Added tests for the bitwise not operator * Added documentation for the bitwise not operator * Updated gemspec using `rake arel.gemspec` --- lib/arel/math.rb | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) (limited to 'lib/arel/math.rb') diff --git a/lib/arel/math.rb b/lib/arel/math.rb index f3dbc7bc49..04cae84598 100644 --- a/lib/arel/math.rb +++ b/lib/arel/math.rb @@ -15,5 +15,29 @@ module Arel def /(other) Arel::Nodes::Division.new(self, other) end + + def &(other) + Arel::Nodes::Grouping.new(Arel::Nodes::BitwiseAnd.new(self, other)) + end + + def |(other) + Arel::Nodes::Grouping.new(Arel::Nodes::BitwiseOr.new(self, other)) + end + + def ^(other) + Arel::Nodes::Grouping.new(Arel::Nodes::BitwiseXor.new(self, other)) + end + + def <<(other) + Arel::Nodes::Grouping.new(Arel::Nodes::BitwiseShiftLeft.new(self, other)) + end + + def >>(other) + Arel::Nodes::Grouping.new(Arel::Nodes::BitwiseShiftRight.new(self, other)) + end + + def ~@ + Arel::Nodes::BitwiseNot.new(self) + end end end -- cgit v1.2.3
