Input

class SomeClass
  def obfuscate_number(number)
    number = number.to_s
    return number if number.length <= 4
    '...' + number[-4, number.length]
  end
end

Output

class SomeClass
  def obfuscate_number(number)
    number = number.to_s
    return number if number.length > 4
    '...' + number[-4, number.length]
  end
end

it appears that comparison operators are being formatted incorrectly

before

• return '12345' if number.length <= 4 # '...2345'
• return '1234' if number.length <= 4 # '1234'

after

• return '12345' if number.length > 4 # '12345'
• return '123' if number.length > 4 which leads to '...' + number[-4, number.length] # TypeError (no implicit conversion of nil into String)
