🐕 Shelldog - Your Faithful Command Companion

Your loyal companion for tracking shell commands - because every good developer needs a faithful friend who remembers everything!

    > ^ <   "Woof! I'm watching... silently."

Shelldog is a silent, intelligent command tracker for your terminal. Think of it as your development diary that writes itself - tracking every command you run, so you never have to remember "what did I do yesterday?" ever again!

🎯 Why Shelldog?

Ever found yourself thinking:

• "What was that curl command I ran last week?"
• "How did I set up this environment again?"
• "I need to write documentation... if only I could remember what I did!"
• "What commands did I run before that bug appeared?"

Shelldog sits quietly in the background and remembers EVERYTHING for you! 🧠

✨ Features

• 🤫 Silent Tracking - Works invisibly without cluttering your terminal
• 🔒 Privacy First - Automatically masks passwords, tokens, and API keys
• 🎯 Smart Detection - Knows when you're in a virtual environment
• 📁 Project-Level Logs - Each venv gets its own history file at the project root
• 🎭 Personality - Because who says CLI tools have to be boring?
• 🚀 Zero Performance Impact - Logs asynchronously in the background
• 🌈 Both Bash & Zsh - Works with your favorite shell

📦 Installation

🔧 How It Works

The Magic Behind the Scenes

1. Shell Hook: Shelldog installs a tiny hook in your shell (via DEBUG trap in Bash or preexec in Zsh)
2. Silent Logger: Every command gets logged asynchronously - zero impact on your workflow
3. Smart Masking: Sensitive data (passwords, tokens, API keys) are automatically masked
4. Venv Detection: Automatically detects if you're in a virtual environment

Virtual Environment Awareness

When you're in a virtual environment:

• Shelldog creates shelldog_history.txt at your project root (next to your venv folder)
• Each project gets its own command history
• No more mixing up commands from different projects!

my-project/
├── venv/
│   └── .shelldog/          # Hidden config folder
├── shelldog_history.txt     # Your project's command history! 📝
├── src/
└── README.md

Privacy & Security

Shelldog automatically masks sensitive information:

# What you type:
export API_KEY=super_secret_key_123

# What gets logged:
export API_KEY=****

Protected patterns:

• export VARNAME=value → export VARNAME=****
• --password, --token, --api-key, --secret
• Authorization headers in curl commands
• And more!

💡 Usage Examples

Example 1: Track Your Development Session

# Start your day
cd my-project
source venv/bin/activate
eval "$(shelldog follow -q)"

# Do your work
git pull origin main
pip install -r requirements.txt
python manage.py migrate
python manage.py runserver

# Later, review what you did
shelldog log --today

Example 2: Debug Like a Pro

# Something broke! What did you do?
shelldog log -n 50

# Find that specific command
shelldog log | grep docker

# See statistics
shelldog stats

Example 3: Document Your Setup

# After setting up a new environment
shelldog log > SETUP.md

# Now you have automatic documentation! 📚

⚙️ Configuration

Log File Locations

• In a venv: <project_root>/shelldog_history.txt
• Global: ~/.shelldog/shelldog_history.txt

State Files

Shelldog keeps its configuration in:

• In a venv: <venv>/.shelldog/
• Global: ~/.shelldog/

🤝 Shell Integration

Manual Activation

If you want to manually control when Shelldog watches:

# Start tracking
source ~/.shelldog/shelldog_hook.sh

# Stop tracking
source ~/.shelldog/shelldog_unhook.sh

Add to Shell Profile (Optional)

Want Shelldog to start automatically? Add to your ~/.bashrc or ~/.zshrc:

# Auto-start Shelldog in virtual environments
if [[ -n "$VIRTUAL_ENV" ]]; then
    eval "$(shelldog follow -q)" 2>/dev/null
fi

🐛 Troubleshooting

"Shelldog is enabled but not logging!"

Make sure the hook is active:

shelldog status

# If hook is not active, run:
eval "$(shelldog follow -q)"

"Commands are logged twice!"

This can happen if you source the hook multiple times. Run:

shelldog stop
eval "$(shelldog follow -q)"

"Shelldog logs its own commands!"

It shouldn't! Shelldog filters itself out. If you see this, please file a bug report! 🐛
