Cursor User Guide: Solve 98% of Development Pain Points

Introduction

As an experienced developer, I am well aware of the various pain points encountered during daily coding: repeatedly checking documentation, insufficiently intelligent code completion, difficulty quickly locating bugs, and time-consuming code refactoring… These problems not only affect development efficiency but also easily interrupt the thought process. Until I encountered Cursor, this AI-driven next-generation IDE, it felt like having a 24/7 programming assistant that can solve 98% of daily development pain points.

This tutorial will help you fully grasp the core functionalities of Cursor, boosting your coding efficiency by 300%. Whether developing new features quickly or refactoring old projects, you will find it effortless.

1. AI Code Completion: Say Goodbye to Tedious Searches

Concept Overview

Cursor integrates a powerful AI model that can intelligently predict and complete code based on context, supporting various mainstream programming languages.

Steps to Operate

1. Enter your code intention in the editor 2. Press Ctrl+Enter to trigger AI completion 3. Choose the appropriate completion suggestion

# Example: Quickly create a Web server
from flask import Flask
app = Flask(__name__)

@app.route('/')  # AI will intelligently complete the route handler function
def home():
    return 'Hello, Cursor!'

if __name__ == '__main__':
    app.run(debug=True)

💡 Tip: Enter comment descriptions of functionality, and the AI can directly generate the corresponding code.

⚠️ Note: It is recommended to check the logic of the AI-generated code when using it for the first time.

2. Intelligent Debugging: Quickly Locate and Fix Issues

Concept Overview

Cursor can automatically analyze code errors and provide repair suggestions, significantly reducing debugging time.

Steps to Operate

1. When a code error occurs, click the error message 2. View the AI analysis results 3. Apply the repair suggestions

// Example: Automatically fix common errors
function calculateTotal(items) {
    let total = 0;
    items.forEach(item => {
        total += item.price * item.quantity;  // AI will check for null values and type errors
    });
    return total.toFixed(2);
}

📌 Key Point: Cursor supports real-time error detection, so you don’t have to wait until runtime to find issues.

3. Code Refactoring Assistant

Concept Overview

Utilizing AI to assist in code refactoring improves code quality and maintainability.

Steps to Operate

1. Select the code block to refactor 2. Right-click and choose “Refactor with AI” 3. Select the refactoring method

// Example: Before refactoring
public void processOrder(Order order) {
    if(order.getStatus() == "PENDING") {
        order.setStatus("PROCESSING");
        // Process order logic
        sendNotification(order);
        updateInventory(order);
        order.setStatus("COMPLETED");
    }
}

// After AI refactoring
public void processOrder(Order order) {
    if(!order.isPending()) return;

    order.setProcessing();
    processOrderSteps(order);
    order.complete();
}

private void processOrderSteps(Order order) {
    sendNotification(order);
    updateInventory(order);
}

💡 Tip: You can guide the AI to refactor according to specific design patterns by using comments during refactoring.

Core Points Summary

1. AI code completion capability is powerful and supports multi-language scenarios 2. Intelligent debugging can quickly locate and fix issues 3. Code refactoring assistant enhances code quality

Practice Recommendations

1. Try using the AI completion feature to complete a small project 2. Practice using the debugging feature to resolve errors in actual projects 3. Perform AI-assisted refactoring on existing code

Remember, the value of a tool lies in its use. It is recommended to start practicing immediately and integrate Cursor into your daily development workflow. Once you master these features, you will find that the joy of programming greatly increases and work efficiency significantly improves.
