How to ignore rubocop check when using guard-rspec?

Question

When I add a guard-rspec gem and set the Guardfile as this:

guard :rspec, cmd: 'bundle exec rspec' do
  watch('spec/spec_helper.rb')                        { "spec" }
  watch('config/routes.rb')                           { "spec/routing" }
  watch('app/controllers/application_controller.rb')  { "spec/controllers" }
  watch(%r{^spec/.+_spec\.rb$})
end

Then run rubocop to check:

rake rubocop:rubocop

It showed:

Guardfile:5:9: C: Use %r only for regular expressions matching more than 1 '/' character.
watch(%r{^spec/.+_spec\.rb$})
      ^^^^^^^^^^^^^^^^^^^^^^

Should I try to find a way to rewrite the regular code or write a ignore code to .rubocop.yml file?

Answer 1

我改变watch(%r{^spec/(.*)/(.*)\\.rb$}) ，然后它通过了。

Answer 2

Rubocop tells you that the extended regex notation %r{} should only be used if the regex itself contains more than 1 / character. Otherwise you should use // notation and escape the / symbol

You can rewrite the line to watch(/^spec\\/.+_spec\\.rb$/) to get rid of the warning without changing the regex itself
