我如何扭转否定条件并在此红宝石语法中交换IF-ELSE分支

发布于 2025-02-09 02:49:26 字数 679 浏览 1 评论 0原文

VS代码在这条线上显示一条线条，我想知道为什么。这是代码行：

if answer != ""

它说：

扭转否定条件并交换if-else分支。

在代码片段下面找到下面

def coach_answer(your_message)
  if your_message.downcase == "i am going to work right now!"
    ""
  elsif your_message.end_with?("?")
    "Silly question, get dressed and go to work!"
  else
    "I don't care, get dressed and go to work!"
  end
end

def coach_answer_enhanced(your_message)
  answer = coach_answer(your_message)
  if answer != ""
    if your_message.upcase == your_message
      "I can feel your motivation! #{answer}"
    else
      answer
    end
  else
    ""
  end
end

VS Code is showing a squiggly line on this line and I wonder why.
Here is the line of code:

if answer != ""

It says:

Invert the negated condition and swap the if-else branches.

Find below the code snippet

def coach_answer(your_message)
  if your_message.downcase == "i am going to work right now!"
    ""
  elsif your_message.end_with?("?")
    "Silly question, get dressed and go to work!"
  else
    "I don't care, get dressed and go to work!"
  end
end

def coach_answer_enhanced(your_message)
  answer = coach_answer(your_message)
  if answer != ""
    if your_message.upcase == your_message
      "I can feel your motivation! #{answer}"
    else
      answer
    end
  else
    ""
  end
end

转换代码：

if obj != expression
  # branch A
else
  # branch B
end

，这意味着您应该从以下方面

if obj == expression
  # branch B
else
  # branch A
end

当Vs说“倒置否定条件并交换If-else分支” 成为==，因此，如果 branch “分支a” 和else branch “分支” b“ 交换了。

应用于您的代码，建议这样写：

def coach_answer_enhanced(your_message)
  answer = coach_answer(your_message)
  if answer == ""
    ""
  else
    if your_message.upcase == your_message
      "I can feel your motivation! #{answer}"
    else
      answer
    end
  end
end

When VS says "Invert the negated condition and swap the if-else branches" it means that you should convert your code from:

if obj != expression
  # branch A
else
  # branch B
end

to:

if obj == expression
  # branch B
else
  # branch A
end

The negated condition != was inverted to become == and accordingly, the if branch "branch A" and the else branch "branch B" were swapped.

Applied to your code, it suggests to write it this way:

def coach_answer_enhanced(your_message)
  answer = coach_answer(your_message)
  if answer == ""
    ""
  else
    if your_message.upcase == your_message
      "I can feel your motivation! #{answer}"
    else
      answer
    end
  end
end
