Tutorial: Coding Assistance

Goal: Explain and refactor a complex piece of legacy code. Level: Advanced Time: 3 minutes

Scenario​

You are looking at a confusing C# function in Visual Studio and don't understand what it does.

Step 1: Select Code​

Highlight the function in your IDE:

public void P(int a) {
    if (a > 10) Console.WriteLine("X");
    else Console.WriteLine("Y");
    // ... more spaghetti code ...
}

Step 2: Trigger Rephlo​

Press Ctrl+Shift+Alt+C.

Step 3: Run "Explain Code"​

Execute a command with the prompt: "Explain this code step-by-step and suggest improvements."

Step 4: Review Explanation​

Rephlo provides a breakdown:

  1. Explanation: "The function P takes an integer... It prints X if..."
  2. Issues: "Variable names are non-descriptive. Logic is nested too deeply."

Step 5: Refactor​

Now run a second command on the same selection: "Refactor Code".

Prompt: "Rename variables to be descriptive and simplify logic."

Output:

public void ProcessThreshold(int thresholdValue)
{
    string message = thresholdValue > 10 ? "X" : "Y";
    Console.WriteLine(message);
}

Step 6: Copy​

Click Copy and paste the clean code back into Visual Studio.
