[Style/SoleNestedConditional] Syntax error when autocorrecting nested if conditions with a block

[tom-kuca]

If there are nested if statesments, where the second if condition is a function with an arugment and a block, autocorrecting causes a syntax error. Given snippet test.rb

def foo
  if cond
    if validate :strict do
        "hello"
      end
    end
  end
end

and running

rubocop test.rb --force-default-config --only Style/SoleNestedConditional -a

there is a syntax error reported by ruby (see below). Prior to autocorrect, there was no syntax error.

---

Expected behavior

ruby test.rb do not report syntax error after autocorrect. Proposed solution is to add parenthesis around arguments.

def foo
  if cond && validate(:strict) do
        "hello"
      end
    end
end

Actual behavior

The source code is autocorrected to

def foo
  if cond && validate :strict do
        puts "hello"
      end
    end
end

ruby test.rb reports syntax error:

/tmp/test.rb:2: syntax error, unexpected symbol literal, expecting `do' or '{' or '('
  if cond && validate :strict do
/tmp/test.rb:5: syntax error, unexpected `end', expecting end-of-input
    end

RuboCop version

$ [bundle exec] rubocop -V
1.33.0 (using Parser 3.1.2.0, rubocop-ast 1.19.1, running on ruby 2.7.4 x86_64-linux)

Thanks for the fix!
