[![Tests](https://github.com/dewe/pysnurr/actions/workflows/tests.yml/badge.svg)](https://github.com/dewe/pysnurr/actions/workflows/tests.yml)

A beautiful terminal spinner library for Python. Provides non-blocking spinner animations at the current cursor position.

## Installation

```bash
pip install pysnurr
```

## Usage

```python
from pysnurr import Snurr, SPINNERS
import time

# Basic usage with context manager (recommended)
with Snurr() as spinner:
    spinner.status = "Working..."
    time.sleep(2)  # Do some work

# Traditional usage
spinner = Snurr()
spinner.start()
spinner.status = "Processing..."
time.sleep(2)  # Do some work
spinner.stop()

# Choose from various spinner styles
spinner = Snurr(frames=SPINNERS["CLASSIC"])  # /-\|
spinner = Snurr(frames=SPINNERS["EARTH"])    # 🌍🌎🌏
spinner = Snurr(frames=SPINNERS["HEARTS"])   # 💛💙💜💚
spinner = Snurr(frames=SPINNERS["MOON"])     # 🌑🌒🌓🌔🌕🌖🌗🌘
...

# Show spinner at end of line
print("Processing", end="")
with Snurr() as spinner:
    time.sleep(2)
print(" Done!")

# Set initial status message
with Snurr(status="Starting up...") as spinner:
    time.sleep(1)
    spinner.status = "Processing..."
    time.sleep(1)

# Update status message during spinning
with Snurr(frames=SPINNERS["EARTH"]) as spinner:
    spinner.status = "Starting a long process..."
    time.sleep(1)
    spinner.status = "Step 1: Data processing"
    time.sleep(1)
    spinner.status = "Step 2: Analysis complete"
```

## Features

- Non-blocking animation
- Dynamic status messages
- Multiple built-in spinner styles:
  - `CLASSIC`: Classic ASCII spinner (/-\|)
  - `ARROWS`: Arrow rotation (←↖↑↗→↘↓↙)
  - `BAR`: ASCII loading bar (▁▂▃▄▅▆▇█▇▆▅▄▃▂▁)
  - `BLOCKS`: Minimal blocks (▌▀▐▄)
  - `DOTS_BOUNCE`: Bouncing dots (.oOᐤ°ᐤOo.)
  - `EARTH`: Earth rotation (🌍🌎🌏)
  - `HEARTS`: Colorful hearts (💛💙💜💚)
  - `MOON`: Moon phases (🌑🌒🌓🌔🌕🌖🌗🌘)
  - `SPARKLES`: Sparkling animation (✨⭐️💫)
  - `TRIANGLES`: Rotating triangles (◢◣◤◥)
  - `WAVE`: Wave pattern (⎺⎻⎼⎽⎼⎻)
- Cursor hiding during animation
- Thread-safe status updates
- Flexible positioning at current cursor position
- Python 3.10+ support
