Blog Post with Copy Code Functionality#

This update adds a "copy code" button to all code blocks in your blog posts. When users hover over a code block, they'll see a copy button that allows them to easily copy the code to their clipboard.

Features Added#

• Click to copy button appears on hover over code blocks
• Visual feedback when code is copied
• Works with all existing code blocks
• Client-side implementation with no server changes required
• Accessible with keyboard navigation

Implementation Details#

1. Created a new client component EnhancedCodeBlock that dynamically adds copy buttons to code blocks
2. Added the component to the blog post page
3. The copy functionality works with any code language and any content

Sample Code Examples#

Here are some examples to demonstrate the copy code functionality.

JavaScript Example#

function calculateTotal(items) {
  return items
    .map(item => item.price * item.quantity)
    .reduce((total, value) => total + value, 0);
}

const cart = [
  { name: 'Widget', price: 9.99, quantity: 2 },
  { name: 'Gadget', price: 14.99, quantity: 1 }
];

const total = calculateTotal(cart);
console.log(`Total: $${total.toFixed(2)}`);

React Component Example#

import React, { useState } from 'react';

function Counter() {
  const [count, setCount] = useState(0);
  
  return (
    <div className="counter">
      <h2>Current count: {count}</h2>
      <button onClick={() => setCount(count + 1)}>
        Increment
      </button>
      <button onClick={() => setCount(count - 1)}>
        Decrement
      </button>
    </div>
  );
}

export default Counter;

CSS Example#

.code-block {
  position: relative;
  background-color: #1e293b;
  border-radius: 0.5rem;
  padding: 1rem;
  margin: 1.5rem 0;
  overflow-x: auto;
}

.copy-button {
  position: absolute;
  top: 0.5rem;
  right: 0.5rem;
  background-color: rgba(255, 255, 255, 0.1);
  border: none;
  border-radius: 0.25rem;
  padding: 0.25rem 0.5rem;
  color: #cbd5e1;
  opacity: 0;
  transition: opacity 0.2s, background-color 0.2s;
}

.code-block:hover .copy-button {
  opacity: 1;
}

.copy-button:hover {
  background-color: rgba(255, 255, 255, 0.2);
  cursor: pointer;
}

Python Example#

def fibonacci(n):
    """Generate Fibonacci sequence up to n"""
    fib_sequence = [0, 1]
    
    while fib_sequence[-1] + fib_sequence[-2] <= n:
        fib_sequence.append(fib_sequence[-1] + fib_sequence[-2])
    
    return fib_sequence

# Generate first 10 Fibonacci numbers
fib_numbers = fibonacci(100)
print(f"Fibonacci sequence up to 100: {fib_numbers}")

# Using list comprehension for even numbers
even_fibs = [num for num in fib_numbers if num % 2 == 0]
print(f"Even Fibonacci numbers: {even_fibs}")
