+

+ + class Ameba::Rule::Naming::BinaryOperatorParameterName + +

+ + + + + + + +

+ + + + Overview +

+ +

A rule that enforces that certain binary operator methods have +their sole parameter named other.

+

For example, this is considered valid:

+
class Money
+  def +(other)
+  end
+end
+

And this is invalid parameter name:

+
class Money
+  def +(amount)
+  end
+end
+

YAML configuration example:

+
Naming/BinaryOperatorParameterName:
+  Enabled: true
+  ExcludedOperators: ["[]", "[]?", "[]=", "<<", "=~"]
+ + + + + +
