module RuboCop
module Cop
module Naming
# This cop checks method 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 3.
# 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 whitelisted names that will never register an
# offense. The `ForbiddenNames` config option takes an array of
# blacklisted names that will always register an offense.
#
# @example
# # bad
# def bar(varOne, varTwo)
# varOne + varTwo
# end
#
# # With `AllowNamesEndingInNumbers` set to false
# def foo(num1, num2)
# num1 * num2
# end
#
# # With `MinArgNameLength` set to number greater than 1
# def baz(a, b, c)
# do_stuff(a, b, c)
# end
#
# # good
# def bar(thud, fred)
# thud + fred
# end
#
# def foo(speed, distance)
# speed * distance
# end
#
# def baz(age_a, height_b, gender_c)
# do_stuff(age_a, height_b, gender_c)
# end
