* Enable `Layout/EmptyLinesAroundAccessModifier` copRyuta Kamizono2019-06-131-0/+4
| | | | | | | | | | | We sometimes say "✂️ newline after `private`" in a code review (e.g. https://github.com/rails/rails/pull/18546#discussion_r23188776, https://github.com/rails/rails/pull/34832#discussion_r244847195). Now `Layout/EmptyLinesAroundAccessModifier` cop have new enforced style `EnforcedStyle: only_before` (https://github.com/rubocop-hq/rubocop/pull/7059). That cop and enforced style will reduce the our code review cost.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Performance cops will be extracted from RuboCop to RuboCop Performance when next RuboCop 0.68 will be released. https://github.com/rubocop-hq/rubocop/issues/5977 RuboCop 0.67 is its transition period. Since rails/rails repository uses Performance cops, This PR added rubocop-performance gem to Gemfile.

| | | | | | | | | | | | | | * Enable `Lint/UselessAssignment` cop to avoid unused variable warnings Since we've addressed the warning "assigned but unused variable" frequently. 370537de05092aeea552146b42042833212a1acc 3040446cece8e7a6d9e29219e636e13f180a1e03 5ed618e192e9788094bd92c51255dda1c4fd0eae 76ebafe594fc23abc3764acc7a3758ca473799e5 And also, I've found the unused args in c1b14ad which raises no warnings by the cop, it shows the value of the cop.

* Enable `Style/RedundantBegin` cop to avoid newly adding redundant begin blockRyuta Kamizono2018-12-211-0/+3
| | | | | | | | | | Currently we sometimes find a redundant begin block in code review (e.g. https://github.com/rails/rails/pull/33604#discussion_r209784205). I'd like to enable `Style/RedundantBegin` cop to avoid that, since rescue/else/ensure are allowed inside do/end blocks in Ruby 2.5 (https://bugs.ruby-lang.org/issues/12906), so we'd probably meets with that situation than before.

| | | | | | | | | | | | | | | | | | | | | Since Rails 6.0 will support Ruby 2.4.1 or higher `# frozen_string_literal: true` magic comment is enough to make string object frozen.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## Summary RuboCop 0.58.2 was released. https://github.com/rubocop-hq/rubocop/releases/tag/v0.58.2 And rubocop-0-58 channel is available in Code Climate. https://github.com/codeclimate/codeclimate/releases/tag/v0.76.0 https://github.com/codeclimate/codeclimate/commit/38f21f0 In addition, the following changes are made in this PR. - Replace Custom cops with Rails cops - Add jaro_winkler gem to Gemfile.lock ### Replace Custom cops with Rails cops These are compatible replacements. - Replace `CustomCops/AssertNot` cop with `Rails/AssertNot` cop. - Replace `CustomCops/RefuteNot` cop with `Rails/RefuteMethods` cop. With this replacement, it was decided to use cop of RuboCop itself. It removes the code related to CustomCops accordingly. ### Add jaro_winkler gem to Gemfile.lock Since RuboCop 0.57.0 depends on jaro_winkler gem, it has been added to Gemfile.lock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We added `assert_not` in f75addd "to replace warty 'assert !foo'". fa8d35b agrees that it is warty, and so do I. This custom Rubocop rule turns the wart into a violation. As with my last custom cop, https://github.com/rails/rails/pull/32441, I want to make sure this looks right on code climate before pushing another commit to autocorrect everything. @toshimaru I just noticed https://github.com/toshimaru/rubocop-rails/pull/26 Is there a better way to add these custom cops, or were you saying we shouldn't have custom cops at all?

* Add custom RuboCop for `assert_not` over `refute`Daniel Colson2018-04-031-0/+7
| | | | | | | | | | | | | | | | | | | | | | | Since at least cf4afc4 we have preferred `assert_not` methods over `refute` methods. I have seen plenty of comments in PRs about this, and we have tried to fix it a few times (5294ad8, e45f176, 8910f12, 41f50be, d4cfd54, 48a183e, and 211adb4), but the `refute` methods keep sneaking back in. This custom RuboCop will take care of enforcing this preference, so we don't have to think about it again. I suspect there are other similar stylistic preferences that could be solved with some custom RuboCops, so I will definitely keep my eyes open. `assert_not` over `assert !` might be a good candidate, for example. I wasn't totally sure if `ci/custom_cops` was the best place to put this, but nothing else seemed quite right. At one point I had it set up as a gem, but I think custom cops like this would have limited value in another context. I want to see how code climate handles the new cops before autocorrecting the existing violations. If things go as expected, I will push another commit with those corrections.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ### Summary This PR changes .rubocop.yml. Regarding the code using `if ... else ... end`, I think the coding style that Rails expects is as follows. ```ruby var = if cond a else b end ``` However, the current .rubocop.yml setting does not offense for the following code. ```ruby var = if cond a else b end ``` I think that the above code expects offense to be warned. Moreover, the layout by autocorrect is unnatural. ```ruby var = if cond a else b end ``` This PR adds a setting to .rubocop.yml to make an offense warning and autocorrect as expected by the coding style. And this change also fixes `case ... when ... end` together. Also this PR itself is an example that arranges the layout using `rubocop -a`. ### Other Information Autocorrect of `Lint/EndAlignment` cop is `false` by default. https://github.com/bbatsov/rubocop/blob/v0.51.0/config/default.yml#L1443 This PR changes this value to `true`. Also this PR has changed it together as it is necessary to enable `Layout/ElseAlignment` cop to make this behavior.
