# Changelog Generator

## Description

This Python script allows you to generate changelogs and release notes based on Redmine tickets.
It uses the OpenAI API to automatically create the changelog entries.

## Features

- Retrieve projects and versions from Redmine
- Retrieve tickets for a specific project and version
- Generate changelog entries based on the ticket information using the OpenAI API
- Output the changelog in AsciiDoc format

## Prerequisites

- Python 3.x
- The following Python packages:
  - urllib
  - json
  - dotenv
  - ssl
  - argparse
- Redmine API key
- OpenAI API key

## Usage

1. Copy the `.env.example` file and rename it to `.env`. Fill in the environment variables `REDMINE_HOST`, `REDMINE_API_KEY`, and `OPENAI_API_KEY` with your access credentials.
2. Run the script with the following arguments:

- `-p, --project`: The project ID for which the changelog should be generated.
- `-f, --fixed-version`: The version ID for which the changelog should be generated.
- `-t, --type`: The type of text to be generated (Changelog or Release Notes).

3. If you don't provide a project ID or version ID, a list of available projects and versions will be displayed for you to choose from.
4. The generated changelog will be output in AsciiDoc format on the console.

```bash
python3 changelog_generator.py -p 47 -f 755 -t Changelog
