## Audio Preventer

**name:** [`@audio_preventer:envs.net`](https://matrix.to/#/@audio_preventer:envs.net)  
**src:** [https://github.com/MTRNord/maubot-audio-preventer](https://github.com/MTRNord/maubot-audio-preventer)

A Bot to prevent voice or audio messages to be sent into a room.

***Note: Bot account requires redact, kick and ban permissions.***

The Audio Preventer is instructed to auto redact those, warn you 3 times as text, then kick you 5 times and then ban you. The counter are per user and across all rooms the bot is in. If you reach the ban level it will ban you on a new voice or audio message also in the other rooms the Audio Preventer is active in.

## RSS Bot

**name:** [`@rss:envs.net`](https://matrix.to/#/@rss:envs.net)  
**src:** [https://github.com/maubot/rss](https://github.com/maubot/rss)

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
- `subscriptions` - List the subscriptions in the current room.

## Reminder

A Bot to remind you about things.

**name:** [`@reminder:envs.net`](https://matrix.to/#/@reminder:envs.net)  
**src:** [https://github.com/maubot/reminder](https://github.com/maubot/reminder)

**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](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones),
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](https://github.com/maubot/reminder/blob/master/reminder/locales.py), content warning: long regexes).

To list your upcoming reminders, use `!remind list`

## Poll Bot

- `results` - Prints out the current results of the poll
- `close` - Ends the poll

Example:

```

`!poll results` - Displays the results from the poll

## Github Bot

A GitHub client and webhook receiver for maubot.

**name:** [`@github:envs.net`](https://matrix.to/#/@github:envs.net)  
**src:** [https://github.com/maubot/github](https://github.com/maubot/github)

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

- `login [flags]` - Log into GitHub.
- `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.

<br />
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.

<br />
2. **Use `!github webhook add <owner>/<repo>` 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**.

## Weather Bot

> > !translate en ru Hello world.

> Привет, мир.

`!tr en ru Hello world.`

The first parameter (source language) can be set to `auto` or omitted entirely
to let Google Translate detect the source language. Additionally, you can reply

replied to.
