gem 'rubocop-ipepe', require: falseYou need to tell RuboCop to load the Ipepe extension. There are three ways to do this:
Put this into your .rubocop.yml.
require: rubocop-ipepeAlternatively, use the following array notation when specifying multiple extensions.
require:
- rubocop-other-extension
- rubocop-ipepeNow you can run rubocop and it will automatically load the RuboCop Ipepe
cops together with the standard cops.
rubocop --require rubocop-ipepeRuboCop::RakeTask.new do |task|
task.requires << 'rubocop-ipepe'
endAll cops are located under
lib/rubocop/cop/ipepe, and contain
examples/documentation.
In your .rubocop.yml, you may treat the Ipepe cops just like any other
cop. For example:
Ipepe/SpecificMatcher:
Exclude:
- spec/my_spec.rbChecks for multiple conditions in unless statement.
# bad
unless foo && bar
do_something
end
# good
if !(foo && bar)
do_something
endProhibits any use of ternary operator.
# bad
foo ? bar : baz
# good
if foo
bar
else
baz
endbundle exec rake 'new_cop[Ipepe/TestOperator]'
