class RuboCop::Cop::Naming::BlockParameterName
Checks block parameter names for how descriptive they are. It is highly configurable.
The ‘MinNameLength` config option takes an integer. It represents the minimum amount of characters the name must be. Its default is 1. The `AllowNamesEndingInNumbers` config option takes a boolean. When set to false, this cop will register offenses for names ending with numbers. Its default is false. The `AllowedNames` config option takes an array of permitted names that will never register an offense. The `ForbiddenNames` config option takes an array of restricted names that will always register an offense.
@example
# bad bar do |varOne, varTwo| varOne + varTwo end # With `AllowNamesEndingInNumbers` set to false foo { |num1, num2| num1 * num2 } # With `MinNameLength` set to number greater than 1 baz { |a, b, c| do_stuff(a, b, c) } # good bar do |thud, fred| thud + fred end foo { |speed, distance| speed * distance } baz { |age, height, gender| do_stuff(age, height, gender) }
