Duplicated Code
Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).
Tuning
This issue has a mass of 70.
We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.
The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.
If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

This cop checks for the use of Time methods without zone.
Built on top of Ruby on Rails style guide (https://github.com/rubocop-hq/rails-style-guide#time) and the article http://danilenko.org/2012/7/6/rails_timezones/
Two styles are supported for this cop. When EnforcedStyle is 'strict' then only use of Time.zone is allowed.
When EnforcedStyle is 'flexible' then it's also allowed to use Time.intimezone.
Example: EnforcedStyle: strict
# `strict` means that `Time` should be used with `zone`.
# bad
Time.now
Time.parse('2015-03-02 19:05:37')
# bad
Time.current
Time.at(timestamp).in_time_zone
# good
Time.zone.now
Time.zone.parse('2015-03-02 19:05:37')
Example: EnforcedStyle: flexible (default)
# `flexible` allows usage of `in_time_zone` instead of `zone`.
# bad
Time.now
Time.parse('2015-03-02 19:05:37')
# good
Time.zone.now
Time.zone.parse('2015-03-02 19:05:37')
# good
Time.current
Time.at(timestamp).in_time_zone
Freeze mutable objects assigned to constants. Open
ALTERNATE_VALUES_FOR = [:name, :acronym]
- Read upRead up
- Exclude checks
This cop checks whether some constant value isn't a mutable literal (e.g. array or hash).
Strict mode can be used to freeze all constants, rather than just literals. Strict mode is considered an experimental feature. It has not been updated with an exhaustive list of all methods that will produce frozen objects so there is a decent chance of getting some false positives. Luckily, there is no harm in freezing an already frozen object.
Example: EnforcedStyle: literals (default)
# bad
CONST = [1, 2, 3]
# good
CONST = [1, 2, 3].freeze
# good
CONST = <<~TESTING.freeze
This is a heredoc
TESTING
# good
CONST = Something.new
Example: EnforcedStyle: strict
# bad
CONST = Something.new
# bad
CONST = Struct.new do
def foo
puts 1
end
end
# good
CONST = Something.new.freeze
# good
CONST = Struct.new do
def foo
puts 1
end
end.freeze
