# Complexity Analyzer

A Python module to analyze time and space complexity of functions using static analysis and runtime profiling, with visualization via graphs.

## Features
- **Static Analysis**: Infers complexity from code structure (e.g., loops, recursion).
- **Profiling**: Measures actual time and memory usage across input sizes.
- **Visualization**: Plots time and space complexity graphs using Matplotlib.
- **Command-Line Interface**: Analyze algorithms directly from the terminal.

## Installation
```bash
pip install complexity-analyzer
```

## Quick Start
```python
from complexity_analyzer import complexity

@complexity
def bubble_sort(arr):
    n = len(arr)
    for i in range(n):
        for j in range(0, n - i - 1):
            if arr[j] > arr[j + 1]:
                arr[j], arr[j + 1] = arr[j + 1], arr[j]
    return arr

# Run with sample data
data = [5, 3, 8, 6, 7, 2]
sorted_data = bubble_sort(data)
# The decorator will automatically:
# 1. Print the static analysis complexity
# 2. Run profiling with varying input sizes
# 3. Display complexity graphs
```

## Usage

### As a Decorator
The simplest way to use Complexity Analyzer is as a decorator:

```python
from complexity_analyzer import complexity

@complexity
def your_function(input_data):
    # Your algorithm here
    return result
```

### Manual Analysis
You can also analyze code directly:

```python
from complexity_analyzer import analyze_code

code = """
def binary_search(arr, target):
    left, right = 0, len(arr) - 1
    while left <= right:
        mid = (left + right) // 2
        if arr[mid] == target:
            return mid
        elif arr[mid] < target:
            left = mid + 1
        else:
            right = mid - 1
    return -1
"""

result = analyze_code(code)
print(result)  # Outputs: "Time Complexity: O(log n), Space Complexity: O(1)"
```

### Advanced Usage

#### Custom Input Sizes
You can customize the input sizes used for profiling:

```python
from complexity_analyzer import complexity

@complexity(input_sizes=[10, 50, 100, 500, 1000])
def your_function(input_data):
    # Your algorithm here
    return result
```

#### Disable Visualization
If you don't want to display the graphs automatically:

```python
from complexity_analyzer import complexity

@complexity(visualize=False)
def your_function(input_data):
    # Your algorithm here
    return result
```

#### Silent Mode
For silent operation without any output:

```python
from complexity_analyzer import complexity

@complexity(verbose=False, visualize=False)
def your_function(input_data):
    # Your algorithm here
    return result
```

## Command-Line Interface

The package provides a command-line interface for quick analysis of Python code:

```bash
# Analyze code directly
complexity-analyzer --code "def bubble_sort(arr):
    n = len(arr)
    for i in range(n):
        for j in range(0, n - i - 1):
            if arr[j] > arr[j + 1]:
                arr[j], arr[j + 1] = arr[j + 1], arr[j]
    return arr"

# Analyze a specific function in a file
complexity-analyzer --file my_algorithm.py --function bubble_sort

# Run and profile a function
complexity-analyzer --file my_algorithm.py --function bubble_sort --run

# Run with custom input sizes and save the plot
complexity-analyzer --file my_algorithm.py --function bubble_sort --run --input-sizes 50 500 5000 --save-plot complexity_plot.png

# Analyze all functions in a file
complexity-analyzer --file my_algorithm.py --analyze-all
```
