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/visitors/to_sql.rb | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'lib/arel/visitors') diff --git a/lib/arel/visitors/to_sql.rb b/lib/arel/visitors/to_sql.rb index 598bf2d984..80bea56ce6 100644 --- a/lib/arel/visitors/to_sql.rb +++ b/lib/arel/visitors/to_sql.rb @@ -801,6 +801,11 @@ module Arel alias :visit_Arel_Nodes_Multiplication :visit_Arel_Nodes_InfixOperation alias :visit_Arel_Nodes_Division :visit_Arel_Nodes_InfixOperation + def visit_Arel_Nodes_UnaryOperation o, collector + collector << " #{o.operator} " + visit o.expr, collector + end + def visit_Array o, collector inject_join o, collector, ", " end -- cgit v1.2.3
