> A minimalist Python profiling library - simple, elegant, and powerful

**Gattopy** makes it easy to measure the performance of your Python code. With just a decorator or a context manager, you can track execution time and memory usage with clean, human-readable output.

## Features

- **Simple to use** - Just add a decorator or use a context manager
- **Time profiling** - Accurate execution time measurement
- **Memory tracking** - Monitor peak and current memory usage
- **Clean output** - Formatted results with detailed statistics
- **Multiple export formats** - JSON, CSV, and Markdown reports
- **Flexible** - Use as decorator or context manager
- **Benchmarking tools** - Compare and analyze function performance
- **Automatic accumulation** - Track multiple function calls automatically
- **Zero dependencies** - Uses only Python standard library

## Installation

```bash
pip install gattopy
```

## Quick Start

### Using the @gatto Decorator

The `@gatto` decorator is the recommended way to profile functions. It automatically accumulates statistics across multiple calls and provides convenient methods to access results.

```python
from gattopy import gatto

# Basic usage - automatic accumulation
@gatto
def process_data(n):
    return sum(range(n))

# Call the function multiple times
process_data(1000)
process_data(5000)
process_data(10000)

# Print accumulated statistics
process_data.print_summary()

# Export results
process_data.export_stats('results.json')
process_data.export_stats('results.csv')

# Get statistics programmatically
stats = process_data.get_stats()
total_calls = process_data.call_count()
```

#### @gatto Parameters

- **`silent`** (bool, default=False): When False, prints execution details for each call. Set to True for batch processing without console output.
- **`return_data`** (bool, default=False): When False, function returns only its result. When True, returns tuple (result, stats).
- **`accumulate`** (bool, default=True): When True, stores all execution statistics in memory for later analysis.
- **`show_args`** (bool, default=True): Display function arguments in output.
- **`track_memory`** (bool, default=True): Track memory usage during execution.

#### @gatto Methods

Decorated functions gain the following methods:

- **`print_summary()`**: Print aggregated statistics for all accumulated calls
- **`get_stats()`**: Return list of all accumulated statistics dictionaries
- **`get_summary()`**: Return summary string without printing
- **`export_stats(filepath)`**: Export statistics to JSON, CSV, or Markdown (auto-detected by extension)
- **`call_count()`**: Return number of times function has been called
- **`clear_stats()`**: Clear all accumulated statistics

#### Silent Mode Example

```python
@gatto(silent=True)
def compute(x):
    return x ** 2

# Run 100 times without console spam
for i in range(100):
    compute(i)

# View summary
compute.print_summary()
print(f"Total executions: {compute.call_count()}")
```

### Using Context Managers

Context managers are ideal for profiling code blocks without modifying function definitions.

```python
from gattopy import Profiler, TimeProfiler, MemoryProfiler

# Time profiling
with TimeProfiler("Data Loading") as profiler:
    data = load_large_dataset()

print(profiler.result)

# Memory profiling
with MemoryProfiler("Data Processing") as profiler:
    processed = process_data(data)

print(profiler.result)

# Combined profiling
with Profiler("Complete Pipeline") as profiler:
    result = run_pipeline()

print(f"Took {profiler.elapsed:.2f} seconds")
```

#### Context Manager Parameters

**Profiler(name, track_memory=True)**
- **`name`** (str): Description of the profiled operation
- **`track_memory`** (bool, default=True): Enable memory tracking

**TimeProfiler(name)**
- **`name`** (str): Description of the profiled operation

**MemoryProfiler(name)**
- **`name`** (str): Description of the profiled operation

## Reporting & Exporting

### Using Reporter for Manual Collection

The Reporter class allows manual collection and aggregation of profiling results.

```python
from gattopy import Reporter
from gattopy.core import Profiler

reporter = Reporter()

# Collect results from multiple profiled operations
with Profiler("Operation 1") as p1:
    result1 = sum(range(100000))

reporter.add_result(p1.result)

with Profiler("Operation 2") as p2:
    result2 = [x ** 2 for x in range(50000)]

reporter.add_result(p2.result)

# Print summary
reporter.print_summary()
```

### Export Formats

```python
# Export to JSON
reporter.save_json("profile_results.json")

# Export to CSV
reporter.save_csv("profile_results.csv")

# Export to Markdown
reporter.save_markdown("profile_results.md")

# Or use @gatto's built-in export
@gatto
def my_function():
    pass

my_function()
my_function.export_stats('results.json')  # Auto-detects format
```

## Benchmarking

Gattopy provides powerful benchmarking tools for performance analysis and function comparison.

### benchmark()

Run a function multiple times and collect detailed statistics.

```python
from gattopy import benchmark, format_time

def my_function():
    return sum(range(1000))

results = benchmark(
    my_function,
    iterations=1000,
    track_memory=True,
    include_iterations=False
)

print(f"Average: {format_time(results['average'])}")
print(f"Median: {format_time(results['median'])}")
print(f"Min: {format_time(results['min'])}")
print(f"Max: {format_time(results['max'])}")
print(f"P95: {format_time(results['p95'])}")
print(f"P99: {format_time(results['p99'])}")
print(f"Std Dev: {format_time(results['std_dev'])}")

if results.get('memory_peak'):
    print(f"Peak Memory: {results['memory_peak']:.2f} MB")
```

### compare_functions()

Compare the performance of multiple functions.

```python
from gattopy import compare_functions

def list_comprehension():
    return [x ** 2 for x in range(1000)]

def map_function():
    return list(map(lambda x: x ** 2, range(1000)))

    map_function,
    generator,
    iterations=500,
    track_memory=True
)

for name, stats in results.items():
    print(f"{name}:")
    print(f"  Average: {format_time(stats['average'])}")
    print(f"  Memory: {stats.get('memory_peak', 0):.2f} MB")

# Using lambda
results = benchmark(lambda: process([1, 2, 3], 10), iterations=1000)

# Using partial
results = benchmark(partial(process, [1, 2, 3], 10), iterations=1000)
```

## Utilities

from gattopy import format_time, format_bytes

# Format time (seconds to human-readable)
print(format_time(0.000001))    # "1.00 μs"
print(format_time(0.001))       # "1.00 ms"
print(format_time(1.5))         # "1.50 s"
print(format_time(65))          # "1m 5.0s"
print(format_time(3665))        # "1h 1m 5.0s"

# Format bytes
print(format_bytes(1024))       # "1.00 KB"
print(format_bytes(1048576))    # "1.00 MB"
