Installation

Using UV (Recommended)

# Clone the repository
git clone <repository-url>
cd stocktool

# Install with uv
uv sync

# Run the DESKTOP application
uv run stock-tool

# OR run the WEB application
uv run stock-tool-web
# Then open browser to http://localhost:5000

Manual Installation

# Install dependencies
pip install sv-ttk pillow requests pyyaml

# Run the application
python src/stocktool/stock_tool_gui_v2.py

Configuration

Create a configuration file at ~/.config/scan_and_import.yaml:

host: https://your-inventree-server.com
token: your-api-token-here

Required Fields

• host: Your InvenTree server URL (without trailing slash)
• token: Your InvenTree API token

Usage

1. Select Location: Scan a location barcode or enter location ID
2. Select Mode: Choose operation mode (Add Stock, Update Stock, Check Stock, or Locate Part)
3. Scan Parts: Scan part barcodes to perform operations

Async Part Import (New!)

When you scan a part that doesn't exist in the system:

1. Part is automatically queued for background import
2. Continue scanning other parts - no waiting required!
3. Watch the "Pending Imports" section to see import progress
4. Part is automatically processed when import completes
5. Failed imports retry automatically (up to 3 attempts)

Benefits:

• No more UI freezing when importing parts
• Scan multiple unknown parts in quick succession
• Visual feedback showing import progress
• Automatic error handling and retry logic

Supported Barcode Formats

The application supports multiple barcode formats:

1. JSON-like format: {PM:PART-CODE,QTY:10}
2. Separator-based format: Fields separated by \x1D or \x1E
