* Change BindParam visit method for Dot to a noopAdam Lassek2016-08-261-1/+2
| | | | | | Since BindParam contains no information, treating it like a string adds no useful information to the graph, and results in an invalid label format.

* | | Support for unified Integer class in Ruby 2.4+yui-knk2016-05-303-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ruby 2.4 unifies Fixnum and Bignum into Integer: https://bugs.ruby-lang.org/issues/12005 Ruby ~2.3 `1234.class` is `Fixnum` and `123456789012345678901234567890.class` is `Bignum`. Ruby 2.4+ `1234.class` is `Integer` and `123456789012345678901234567890.class` is `Integer`. So what we should do is defining `visit_Integer` method to visitors.

* * Support for bitwise operations as infix operators. Tests included.Shahbaz Javeed2016-01-065-0/+85
| | | | | | | | | | | | | | | | | | | | | | *** 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`

* Inject the visitor rather than relying on other objects internalsSean Griffin2015-12-172-2/+7
| | | | | | This is ultimately messy no matter what, and increases the coupling to the database backend, but we can at least contain it somewhat into an object that's already coupled.
* Delegate to Connection Visitor in WhereSQL VisitorEdward Paget2015-12-171-1/+5
| | | | | | | | | | | | The WhereSQL visitor always uses the generic ToSQL visitor to create the where clause sql statement. This means that it'll miss database specific statements, such as 'ILIKE' in PostgreSQL. Since the `#where_sql` method is mainly used for ActiveRecord error reporting, this discrepancy could be confusing to users. This patch changes the WhereSQL visitor to use the its connection visitor to generate SQL for each statement in the SelectManager's wheres array. Then lets them be joined together with ' AND '.

* Change the interface of `having` to match that of `where`Sean Griffin2015-01-276-16/+18
| | | | | | These two clauses have nearly identical semantics with regards to how they would be constructed as an AST. It doesn't make sense for their interfaces to be separate.
* Implement equality for `BindParam`Sean Griffin2015-01-251-0/+3
| | | | | It is impossible to test equality of things constructing trees with bind params otherwise.
* Allow a type caster to be given to the `Arel::Table` objectSean Griffin2014-12-295-16/+55
| | | | | | | | | This will allow most consuming code to avoid the deprecation introduced in 008445d6fd5f825d9b445ac75a7be67f0f7ab52c. The only code which will be affected is code that is building the `Arel::Table` object manually, rather than calling `arel_table` on an Active Record class. Hopefully this case will be rare enough that we don't need to introduce any additional APIs to work around it.
* Deprecate automatic type casting within ArelSean Griffin2014-12-261-0/+11
| | | | | | | | Rails now performs all casting eagerly, before passing the value into Arel. Once we remove this, the code on both sides will be simplified greatly. Ideally, we can provide the appropriate public APIs on the Rails side to ease this transition for library authors who depend on this behavior.
* Allow for handling quoted values in rangesSean Griffin2014-12-261-6/+14
| | | | | Since Active Record needs to eagerly cast values, we need to check for quoted infinity in our range handling
* {Matches,DoesNotMatch} support the ESCAPE clause with PostgreSQLKazuya NUMATA2014-12-251-2/+14
