v0.3.0 - Session Summary Generation Tool (2025-12-22)

What Changed?

This release introduces a new create_session_summary.py script that automatically generates comprehensive session summary TOML files from collected event data. The tool analyzes event timestamps to extract measurement metadata, device information, and location details, providing a structured format for measurement documentation.

What's New

Main Feature: Session Summary Generator

What it does: Automatically creates a structured TOML file containing comprehensive measurement session information, including event statistics, device metadata, timestamps in JST (Japan Standard Time), and location/device orientation fields for future data collection.

How to use it:

# Basic usage
uv run create_session_summary.py ./measurement_directory

# With verbose output
uv run create_session_summary.py ./measurement_directory --verbose

Generated TOML Structure:

The script creates session_summary.toml with the following sections:

  • [overview]: Run metadata, event counts, timestamps, duration
  • [device]: MAC address, firmware versions (kurikintons, kazunoko)
  • [description]: Short/long descriptions, remarks, commands used
  • [location]: Device location, coordinates, orientation angles
  • [files]: List of event data files processed

Installation

Quick Start

# Get the release
git checkout vX.Y.Z

# Setup
task env:setup

# Run CLI
uv run kazunoko --help

What's Different from the Last Version?

✅ Added

  • New create_session_summary.py script for automated session summary generation
  • PEP 723 compliant uv script executable via uv run
