This PR fixes the following incorrect auto-correct for EnforcedStyle: require_parentheses of Style/MethodCallWithArgsParentheses with EnforcedStyle: conditionals of Style/AndOr.

% cat example.rb
if foo and bar :arg
end

% rubocop --only Style/AndOr,Style/MethodCallWithArgsParentheses -a
(snip)

Offenses:

example.rb:1:8: C: [Corrected] Style/AndOr: Use && instead of and.
if foo and bar :arg
       ^^^
example.rb:1:12: C: [Corrected] Style/MethodCallWithArgsParentheses: Use
parentheses for method calls with arguments.
if foo and bar :arg
           ^^^^^^^^

Before

% cat example.rb
if foo && bar(:arg))
end

% ruby -c example.rb
example.rb:1: syntax error, unexpected ')', expecting `then' or ';' or '\n'
if foo && bar(:arg))

After

% cat example.rb
if foo && bar(:arg)
end

Before submitting the PR make sure the following are checked:

  • The PR relates to only one subject with a clear title and description in grammatically correct, complete sentences.
  • Wrote good commit messages.
  • Commit message starts with [Fix #issue-number] (if the related issue exists).
  • Feature branch is up-to-date with master (if not - rebase it).
  • Squashed related commits together.
  • Added tests.
  • Ran bundle exec rake default. It executes all tests and runs RuboCop on its own code.
  • Added an entry (file) to the changelog folder named {change_type}_{change_description}.md if the new code introduces user-observable changes. See changelog entry format for details.
