Quick Start

Command Line

# Generate schema interactively
python -m fakestack.runner -g .

# Download example schema
python -m fakestack.runner -d .

# Create database and populate with fake data
python -m fakestack.runner -c -p -f schema.json

Or use the installed command:

fakestack -g .              # Interactive schema generator
fakestack -d .              # Download example
fakestack -c -p -f schema.json

Python API

from fakestack import fakestack

# Download schema
fakestack(['-d', '.'])

# Create and populate database
fakestack(['-c', '-p', '-f', 'schema.json'])

Schema Example

{
  "database": {
    "db_type": "sqlite",
    "db_name": "test.db"
  },
  "tables": [
    {
      "name": "users",
      "count": 50,
      "columns": [
        {"name": "id", "type": "INTEGER PRIMARY KEY AUTOINCREMENT"},
        {"name": "name", "type": "TEXT", "fake": "name"},
        {"name": "email", "type": "TEXT", "fake": "email"},
        {"name": "phone", "type": "TEXT", "fake": "phoneformatted"},
        {"name": "address", "type": "TEXT", "fake": "address"},
        {"name": "created_at", "type": "TEXT", "fake": "date"}
      ]
    }
  ]
}

How It Works

This package bundles pre-compiled Go binaries for all major platforms. When you run fakestack, the Python wrapper:

1. Detects your OS and architecture
2. Selects the appropriate binary from fakestack/bin/
3. Executes it with your arguments
4. Returns the exit code

This approach provides:

• ✅ Zero runtime dependencies
• ✅ Native performance
• ✅ Easy installation
• ✅ Cross-platform compatibility
