YARB

Yet Another Reminder Bot

YARB can be used to create reminders for a specific time at a day. It uses the Trixnity framework.

Features

  • Create reminders for a specific time at the current day.
  • Change display name per room
  • Configure an offset for the reminder time
  • Simple rights management (same as for my other bots)

Functions

Setup

  1. Get a matrix account for the bot (e.g., on your own homeserver or on matrix.org)
  2. Prepare configuration:
    • Copy config-sample.json to config.json
    • Enter baseUrl to the matrix server and username / password for the bot user
    • Add yourself to the admins (and delete my account from the list :))
    • You can limit the users that can interact with the bot by defining the users list
  3. Either run the bot via jar or run it via the provided docker.
    • If you run it locally, you can use the environment variable CONFIG_PATH to point at your config.json (defaults to ./config.json)
    • If you run it in docker, you can use a command similar to this docker run -itd -v $LOCAL_PATH_TO_CONFIG:/usr/src/bot/data/config.json:ro ghcr.io/dfuchss/yarb

Usage

  • An admin can invite the bot to an unencrypted room. If the room has enabled encryption or if the invite was not sent by an admin, the bot ignores it (without logging it)
  • After the bot has joined use !yarb help to get an overview about the features of the bot (remember: the bot only respond to users)
  • In order to create a new reminder use !yarb <time> <message>. The time has to be in the format HH:mm (e.g., !yarb 12:00 Lunch time!).
  • You can configure the bot name in the config.json

Development

I’m typically online in the Trixnity channel. So feel free to tag me there if you have any questions.

  • The bot is build using the Trixnity framework.
  • The basic functionality is located in Main.kt. There you can also find the main method of the program.
