**Schedule Python tasks with one line of code. Works everywhere. Now with async support, task persistence, and safe mode!**

AutoCron makes task scheduling painless—no cron syntax, no platform-specific setup. Just Python.

📊 **Status:** Active development | Small/medium production ready | [Enterprise-ready in 3 weeks](ACTION_PLAN.md)

## 🚀 Quick Start

**Install:**
```bash
pip install autocron-scheduler[all]  # With all features
```

**Schedule a task:**
```python
from autocron import schedule

@schedule(every='5m')
def my_task():
    print("Running every 5 minutes!")

# Or use async!
@schedule(every='10m')
async def async_task():
    await fetch_data()
```

That's it. AutoCron handles the rest.

## ✨ What's New in v1.2.0

### � **Safe Mode** (Security & Resource Control)
Run untrusted scripts safely with subprocess isolation and resource limits!

```python
scheduler.add_task(
    name="untrusted_script",
    script="user_script.py",
    every="1h",
    safe_mode=True,        # Subprocess isolation
    max_memory_mb=256,     # Memory limit
    timeout=300            # Hard timeout
)
```

**Features:**
- ✅ Process isolation (failures don't affect parent)
- ✅ Memory limits (prevents OOM crashes)
- ✅ CPU limits (prevents system lockup - Unix)
- ✅ Timeout enforcement at OS level
- ✅ Output sanitization (10KB limit)

**Perfect for:**
- User-provided scripts (Unix/Linux/Mac with full resource limits)
- Multi-tenant environments (subprocess isolation on all platforms)
- Production systems with strict SLAs
- Processing untrusted data

**Note:** Windows currently supports subprocess isolation and timeout, but not memory/CPU limits. Full Windows Job Objects support coming soon.

### �🔄 **Async/Await Support**
Schedule async functions natively—no extra configuration needed!

```python
@schedule(every='5m')
async def fetch_api():
    async with aiohttp.ClientSession() as session:
        data = await session.get('https://api.example.com')
        return await data.json()
```

### 💾 **Task Persistence**
Save and restore tasks across system restarts. Your schedules survive reboots!

```python
scheduler = AutoCron()
scheduler.add_task(name="backup", script="backup.py", every="1h")

# Save tasks to file
scheduler.save_tasks("my_tasks.yaml")

# Load them back after restart
scheduler.load_tasks("my_tasks.yaml")
```

### 📊 **Visual Dashboard**
Monitor task execution with beautiful terminal dashboards!

```bash
autocron dashboard          # View all tasks
autocron stats task_name    # Detailed analytics
autocron dashboard --live   # Real-time monitoring
```

## 💡 Examples

### Simple Decorator

```python
from autocron import schedule

@schedule(every='30m')
def fetch_data():
    # Runs every 30 minutes
    print("Fetching data...")

@schedule(cron='0 9 * * *')  # Every day at 9 AM
def daily_report():
    print("Generating report...")
```

### Async Tasks (New in v1.2!)

```python
import aiohttp
from autocron import schedule

@schedule(every='5m')
async def fetch_async():
    async with aiohttp.ClientSession() as session:
        async with session.get('https://api.example.com') as resp:
            return await resp.json()

@schedule(every='10m')
async def process_data():
    # Multiple async operations
    results = await asyncio.gather(
        fetch_data_1(),
        fetch_data_2(),
        fetch_data_3()
    )
    return results
```

### Task Persistence (New in v1.2!)

```python
from autocron import AutoCron

scheduler = AutoCron()

# Add tasks
scheduler.add_task(
    name="backup",
    script="backup.py",
    every='1h',
    retries=3
)

# Save to file (survives restarts!)
scheduler.save_tasks()  # Saves to ~/.autocron/tasks.yaml

# Later, after system restart...
scheduler.load_tasks()  # Restores all tasks
scheduler.start()
```

### Visual Dashboard (New in v1.1!)

```bash
# View task summary
autocron dashboard

# Task details with analytics

show_dashboard()  # Display all tasks
show_task("backup_task")  # Show specific task stats
```

### Scheduler Class

    notify='desktop'
)

scheduler.start()
```

### With Retry & Timeout

```python
@schedule(every='10m', retries=3, timeout=60)

    response = requests.get('https://api.example.com/data')
    return response.json()
```
