korb 0.3.1

🏀 korb
A CLI toolkit for DBB basketball league analysis

korb is a zero-dependency Python CLI that parses HTML from the DBB (Deutscher Basketball Bund) legacy JSP platform and provides standings, results, schedules, predictions, and more.

Features

• 📊 Standings — full league table with points, differentials, averages
• 🏀 Team — game-by-game results, sparklines, quality metrics
• 📋 Ergebnisse — all completed game results with optional team filter
• 📅 Schedule — with back-to-back detection, filtering, pending games
• 🔮 Predict — efficiency-model-based final standings forecast
• 🥇 Top — quick leaderboard with ASCII bar chart
• 📥 Download — fetch fresh HTML data directly from basketball-bund.net
• 🔧 --json — machine-readable output for data commands (not download)

Installation

# With uv (recommended)
git clone https://github.com/malvavisc0/korb && cd korb
uv sync

# With pip (end-user install)
pip install .

After installation, the korb CLI is available inside the virtual environment. Use uv run korb to invoke it, or activate the venv first.

Quick Start

# Download league data
uv run korb --ligaid 51187 download

# View standings
uv run korb --ligaid 51187 standings

# Download fresh data + predict in one go
uv run korb --ligaid 51187 --download predict

Finding your Liga ID

The --ligaid value comes from the liga_id parameter in the DBB league URL:

https://www.basketball-bund.net/index.jsp?Action=103&liga_id=51187
                                                           ^^^^^
                                                           this is your liga ID

Global flags

How Predictions Work

The predict command estimates final standings using a multiplicative efficiency model:

Data Notes

• DBB encodes forfeits as 20:0 / 0:20; korb counts them as completed games, awards the winner 2 points, and deducts 1 point from the loser.
• Struck-through and cancelled rows are skipped.
