GPT Changelog

GPT Changelog is a powerful tool that automatically generates high-quality changelogs using OpenAI's advanced language models. By analyzing commit messages since the most recent tag, GPT Changelog creates a well-structured, markdown-formatted changelog and seamlessly integrates it into your CHANGELOG.md file.

Features

• Fast and Efficient: Quickly generates changelogs by leveraging OpenAI's GPT models.
• High Quality: Produces clear, concise, and informative changelogs to keep your project documentation up-to-date.
• Seamless Integration: Automatically prepends the generated changelog to your existing CHANGELOG.md file or creates one if it doesn't exist.
• Customizable: Supports configuration of the OpenAI model and context token limits.
• Semantic Versioning: Determines the next version number based on semantic versioning principles.

Installation

Prerequisites

• Python 3.6 or higher: Ensure that Python is installed on your system.
• OpenAI API Key: You need an OpenAI API key to use this tool. Sign up at OpenAI to obtain one.

Using pip

Install GPT Changelog via pip:

pip install gptchangelog

Configuration

Before using GPT Changelog, you need to configure your OpenAI API key and settings. You can initialize the configuration using the built-in command:

gptchangelog config init

This command will guide you through setting up your configuration file, where you can specify your OpenAI API key, the model to use, and other settings.

By default, the configuration file is created in one of the following locations:

• Global Configuration: $HOME/.config/gptchangelog/config.ini
• Project Configuration: ./.gptchangelog/config.ini

Manual Configuration

Alternatively, you can manually create a configuration file named config.ini with the following content:

[openai]
api_key = your_openai_api_key_here
model = gpt-4
max_context_tokens = 8000

• Replace your_openai_api_key_here with your actual OpenAI API key.
• Set the model parameter to the desired OpenAI model (e.g., gpt-4 or gpt-3.5-turbo).
• Optionally adjust max_context_tokens based on your model's token limit.

Usage

Navigate to your Git repository directory and run:

gptchangelog

This command will:

1. Fetch commit messages since the most recent tag or specified commit.
2. Refine commit messages for clarity and conciseness.
3. Determine the next version number based on semantic versioning.
4. Generate a changelog using the specified OpenAI model.
5. Prepend the generated changelog to the CHANGELOG.md file. If the file doesn't exist, it will create one.

Command-Line Options

• --since <commit>: Specify the commit hash or tag to start fetching commit messages from. If not provided, it uses the most recent tag.

Example:

gptchangelog --since v1.2.3

Configuration Commands

• gptchangelog config init: Initialize the configuration file.
• gptchangelog config show: Display the current configuration.

Example

Here's how to use GPT Changelog:

cd /path/to/your/repo
gptchangelog

Within seconds, your CHANGELOG.md will be updated with the latest changes, keeping your project documentation current and professional.
