mastobots

A customizable Mastodon bot that periodically retrieves RSS feed items containing specified keywords, analyzes them in Japanese (using Juman++) or English (using Prose), and then posts automatically-generated Japanese comments. It also responds to mentions and provides weather information.

RSS feed items are stored in a MySQL database and analyzed for relevant keywords. Japanese items are parsed with Juman++, and English items are processed using Prose, but all posts are generated in Japanese.

Populate RSS items into the database beforehand using tools such as feedAggregator.

Configure multiple bots simultaneously via the config.yml file.

Dependencies

Install the following before running:

• MySQL
• Juman++ 2.0.0-rc3

Features

• Supports Japanese and English RSS feed items (all posts in Japanese).
• Highly customizable posting intervals, comments, and keywords.
• Responds positively or negatively to mentions containing the keyword "いい" plus a bot-specific suffix.
• Automatically follows users who mention it with the word "フォロー" (follow).
• Provides weather forecasts for requested location and time (current, today, tomorrow, day after tomorrow) using OpenWeatherMap. Mention "体感" (feels-like) to get perceived temperature.
• Configurable sleeping/waking hours. The bot is inactive during sleep hours. Set identical times to stay active continuously.
• With LivesWithSun set to true, sleep cycles synchronize to local sunrise/sunset based on latitude/longitude (Yahoo! YOLP API required).
• Randomly timed posts enabled via RandomFrequency and defined in RandomToots.
• Run the bot for a limited time using the -p <minutes> option.

Usage

1. Import the schema (database_tables.sql) into your MySQL database and periodically populate RSS items (e.g., using feedAggregator).
2. In cmd/mastobots, run go build to compile the mastobots binary.
3. Copy config.yml.example to config.yml and edit accordingly.
4. Launch the bot with ./mastobots. Using systemd or screen for background execution is recommended.
