RSS Bot

name: @rss:envs.net

A Bot that posts RSS feed updates to Matrix.

Usage: !rss <subcommand> [...]

• subscribe <feed URL> - Subscribe this room to a feed.
• unsubscribe <feed ID> - Unsubscribe this room from a feed.
• template <feed ID> <new template> - Change the notification template for a subscription in this room
• notice <feed ID> [true/false] - Set whether or not the bot should send updates as m.notice

Reminder

A Bot to remind you about things.

name: @reminder:envs.net

Usage: !remind <date> [message] OR !remind <subcommand> [...]

Subcommands: reschedule, help, list, locales, locale, timezone

<date> can be a time delta (e.g. 2 days 1.5 hours or friday at 15:00) or an absolute date (e.g. 2020-03-27 15:00).

To set the timezone for date parsing and output for your messages, use !remind tz <timezone>. It's recommended to use a TZ database name, but anything supported by Pytz will work.

Similarly, you can set the locale for date parsing with !remind locale <list of locales>. If you provide multiple locales, each one will be tried for parsing your input until one matches. Unlike the timezone, the locale only affects input, not output. You can view available locales using !remind locales. You can also contribute new locales by making a pull request (see locales.py, content warning: long regexes).

To list your upcoming reminders, use !remind list

Github Bot

A GitHub client and webhook receiver for maubot.

name: @github:envs.net

Usage: !github <subcommand> [...]

• ping - Check your login status.
• raw <query> - Make a raw GraphQL query.
• create [owner/repo] <title and body> - Create an issue. Title on first line, body on other lines
• webhook <subcommand> [...] - Manage webhooks.

1. **Use `!github login` to log in.**

After inviting your bot / client to a matrix channel, use the !gh or !github command to use the github instance.

Using gh login first is mandatory and needed once per instance.

The bot will reply with a link leading to your personal Github's allowed OAuth apps page, where you shall grant the necessary rights to the bot OAuth app.

By default, the bot will request access to all public repos and to add webhooks. You can control the permissions it wants with some flags:

• --no-repo makes it not ask for repo access at all. Only !github webhook add will work, other commands like !github create will not.
• --no-hook makes it not ask for webhook access. !github webhook add will not work.
• --private makes it ask for private repo access. Necessary if you want to use the bot to manage private repos.

2. **Use `!github webhook add /` to add webhooks.**

This will let you see in the current channel all the commits, comments, issues, stars, forks, pull requests, and so on, for that given repository.

You must have admin rights on the repositories you want to track, as adding webhooks to a repository requires manager access rights to a project.

Once you create a webhook and track a repository, it will be tracked only in the room from which you are in.
