Basic Examples
--------------

Simple Python Function
^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: python

    from CodeVideoRenderer import CameraFollowCursorCV

    code = '''
    def fibonacci(n):
        """Calculate the nth Fibonacci number"""
        if n <= 1:
            return n
        return fibonacci(n-1) + fibonacci(n-2)

    # Example usage
    result = fibonacci(10)
    print(f"Fibonacci(10) = {result}")
    '''

    video = CameraFollowCursorCV(
        code=('string', code),
        language='python',
        formatter_style='github-dark',
        video_name='FibonacciExample'
    )
    video.render()

JavaScript Example
^^^^^^^^^^^^^^^^^^

.. code-block:: python

   js_code = '''
   function debounce(func, wait) {
       let timeout;
       return function executedFunction(...args) {
           const later = () => {
               clearTimeout(timeout);
               func(...args);
           };
           clearTimeout(timeout);
           timeout = setTimeout(later, wait);
       };
   }

   // Usage example
   const debouncedSearch = debounce(searchFunction, 300);
   '''

   video = CameraFollowCursorCV(
       code=('string', js_code),
       language='javascript',
       formatter_style='monokai'
   )
   video.render()

Intermediate Examples
---------------------

File-based Animation
^^^^^^^^^^^^^^^^^^^^

Animate code from an existing file:

.. code-block:: python

   video = CameraFollowCursorCV(
       code=('file', 'src/algorithm.py'),
       language='python',
       video_name='AlgorithmImplementation'
   )
   video.render()

Custom Typing Speed
^^^^^^^^^^^^^^^^^^^

Simulate different coding styles:

.. code-block:: python

    # Fast typing (expert coder)
    video_fast = CameraFollowCursorCV(
        code=('string', 'code'),
        language='python',
        interval_range=(0.03, 0.06)
    )

    # Slow typing (learning/teaching)
    video_slow = CameraFollowCursorCV(
        code=('string', 'code'),
        language='python',
        interval_range=(0.2, 0.4)
    )

Advanced Examples
-----------------

Multi-language Demonstration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Showcase code in different programming languages:

.. code-block:: python

    languages_examples = [
        ('python', 'print("Hello, World!")'),
        ('javascript', 'console.log("Hello, World!");'),
        ('java', 'System.out.println("Hello, World!");'),
        ('cpp', 'printf("Hello, World!");')
    ]

    for lang, code in languages_examples:
        video = CameraFollowCursorCV(
            code=('string', code),
            language=lang,
            video_name=f'{lang}_example'
        )
        video.render()

Custom Styling
^^^^^^^^^^^^^^

Experiment with different syntax highlighting themes:

.. code-block:: python

    styles = ['github-dark', 'monokai', 'solarized-dark', 'dracula']

    for style in styles:
        video = CameraFollowCursorCV(
            code=('string', 'example_code'),
            language='python',
            formatter_style=style,
            video_name=f'style_{style}'
        )
        video.render()

Real-world Use Cases
--------------------

Algorithm Explanation
^^^^^^^^^^^^^^^^^^^^^

Demonstrate sorting algorithms:

.. code-block:: python

    sorting_code = '''
    def quicksort(arr):
        if len(arr) <= 1:
            return arr
        pivot = arr[len(arr) // 2]
        left = [x for x in arr if x < pivot]
        middle = [x for x in arr if x == pivot]
        right = [x for x in arr if x > pivot]
        return quicksort(left) + middle + quicksort(right)

    # Example usage
    numbers = [3, 6, 8, 10, 1, 2, 1]
    sorted_numbers = quicksort(numbers)
    '''

Code Review Demonstration
^^^^^^^^^^^^^^^^^^^^^^^^^

Show before/after code improvements:

.. code-block:: python

    # Original code
    original = '''
    def calculate_total(items):
        total = 0
        for item in items:
            total += item.price
        return total
    '''

    # Improved code
    improved = '''
    from typing import List
    from dataclasses import dataclass

    @dataclass
    class Item:
        price: float

    def calculate_total(items: List[Item]) -> float:
        """Calculate total price of items."""
        return sum(item.price for item in items)
    '''
