runce 0.1.5

Ensure only one instance of your process runs at a time.

Runce

🚀 The One-and-Done Process Wrangler

"Runce and done! No repeats, no retreats!" 🏃‍♂️💨
🔒 Guaranteed Singleton Execution • 📊 Process Tracking • ⏱️ Lifecycle Management

Features ✨

• 🚫 No Duplicates: Each command runs exactly once per unique ID
• 📝 Process Tracking: View all managed processes with status
• ⏱️ Execution Time: Track how long processes have been running
• 📂 Log Management: Automatic stdout/stderr capture
• 🛑 Clean Termination: Proper process killing

Installation 📦

pip install runce

Usage 🛠️

# Run a singleton process
runce run --id my-process -- python script.py

# List all processes
runce list

# View output
runce tail my-process -n 20

# Stop a process
runce kill my-process

# Restart a process
runce restart my-process

# Clean dead processes
runce clean

Examples 💡

1. Running a Background Service

runce run --id api-server -- python api.py

2. Checking Running Processes

$ runce list
PID     NAME        STATUS      ELAPSED    COMMAND
1234    api-server  ✅ Running  01:23:45   python api.py
5678    worker      ❌ Stopped  00:45:30   python worker.py

3. Preventing Duplicates

$ runce run --id daily-job -- python daily.py
🚀 Started: PID:5678(✅ Running) daily-job

$ runce run --id daily-job -- python daily.py
🚨 Already running: PID:5678(✅ Running) daily-job

How It Works ⚙️

1. Process Locking: Each --id creates a lock file
2. PID Tracking: Running processes are tracked in JSON files
3. Singleton Enforcement: Duplicate execution prevented
4. Cleanup: Dead processes can be automatically cleaned
