# 示例代码

本项目包含JavaScript和Python的示例代码，用于测试代码执行功能。

## JavaScript示例

[examples/test_js.js](mdc:examples/test_js.js)是一个简单的JavaScript示例，包含：

```javascript
// Sample JavaScript file with handler function

// Log some debug information
console.log("Initializing JavaScript test...");

// Define a simple add function
function add(a, b) {
    console.log(`Adding ${a} + ${b}`);
    return a + b;
}

// Some processing
const numbers = [1, 2, 3, 4, 5];
console.log("Processing numbers:", numbers);

// Handler function that will be called to get the result
function handler() {
    console.log("Handler function called");
    
    // Calculate sum
    const sum = numbers.reduce((acc, num) => add(acc, num), 0);
    console.log("Final calculation completed");
    
    return `The sum of [${numbers.join(", ")}] is ${sum}`;
} 
```

执行这个示例将输出：

```
--- Logs ---
Initializing JavaScript test...
Processing numbers: [1,2,3,4,5]
Handler function called
Adding 0 + 1
Adding 1 + 2
Adding 3 + 3
Adding 6 + 4
Adding 10 + 5
Final calculation completed
------------
Result: The sum of [1, 2, 3, 4, 5] is 15
```

## Python示例

[examples/test_python.py](mdc:examples/test_python.py)是一个简单的Python示例，包含：

```python
#!/usr/bin/env python3
# Sample Python file with handler function

import time

# Log some debug information
print("Initializing Python test...")

# Define a simple function
def multiply(a, b):
    print(f"Multiplying {a} * {b}")
    return a * b

# Some processing
numbers = [1, 2, 3, 4, 5]
print(f"Processing numbers: {numbers}")

# Handler function that will be called to get the result
def handler():
    print("Handler function called")
    
    # Calculate product
    product = 1
    for num in numbers:
        product = multiply(product, num)
    
    print("Final calculation completed")
    
    return f"The product of {numbers} is {product}"

# This part won't be executed when the code is run through the MCP runner
if __name__ == "__main__":
    print("Running directly, calling handler...")
    result = handler()
    print(f"Result: {result}")
```

执行这个示例将输出：

```
--- Logs ---
Handler function called
Multiplying 1 * 1
Multiplying 1 * 2
Multiplying 2 * 3
Multiplying 6 * 4
Multiplying 24 * 5
Final calculation completed
------------
Result: The product of [1, 2, 3, 4, 5] is 120
```

## 如何创建自己的示例

创建自己的示例代码时，需要遵循以下规则：

1. 必须包含一个名为`handler`的函数，作为执行结果的返回点
2. `handler`函数的返回值将作为执行结果
3. 使用`console.log`（JavaScript）或`print`（Python）输出日志
4. 可以定义其他函数和变量，它们将在执行过程中被使用

示例：

```javascript
// JavaScript示例
function handler() {
    return "Hello from JavaScript!";
}
```

```python
# Python示例
def handler():
    return "Hello from Python!"
```
