Too Many Instance Variables
is a special case of LargeClass
.
Example
Given this configuration
TooManyInstanceVariables:
max_instance_variables: 3
and this code:
class TooManyInstanceVariables
def initialize
@arg_1 = :dummy
@arg_2 = :dummy
@arg_3 = :dummy
@arg_4 = :dummy
end
end
Reek would emit the following warning:
test.rb -- 5 warnings:
[1]:TooManyInstanceVariables has at least 4 instance variables (TooManyInstanceVariables)
FrOData::Service::Request#params is a writable attribute Open
attr_accessor :params
- Read upRead up
- Exclude checks
A class that publishes a setter for an instance variable invites client classes to become too intimate with its inner workings, and in particular with its representation of state.
The same holds to a lesser extent for getters, but Reek doesn't flag those.
Example
Given:
class Klass
attr_accessor :dummy
end
Reek would emit the following warning:
reek test.rb
test.rb -- 1 warning:
[2]:Klass declares the writable attribute dummy (Attribute)
FrOData::Service::Request#method is a writable attribute Open

This cop (by default) checks for uses of methods Hash#haskey? and
Hash#hasvalue? where it enforces Hash#key? and Hash#value?
It is configurable to enforce the inverse, using verbose
method
names also.
Example: EnforcedStyle: short (default)
# bad Hash#haskey? Hash#hasvalue?
# good Hash#key? Hash#value?
Example: EnforcedStyle: verbose
# bad Hash#key? Hash#value?
# good Hash#haskey? Hash#hasvalue?
