# Draupnir
|
|
|
|
A highly capable [Matrix](https://matrix.org) moderation bot and protection
|
|
platform, trusted by room moderators and homeserver admins alike.
|
|
|
|
Visit [#draupnir:matrix.org](https://matrix.to/#/#draupnir:matrix.org) in your
|
|
client and come say hi.
|
|
|
|
Please see the
|
|
[draupnir documentation](https://the-draupnir-project.github.io/draupnir-documentation/)
|
|
for installation instructions and usage guides.
|
|
|
|
## Features
|
|
|
|
- Draupnir's UX is centred around prompting you with questions to carry out
|
|
specific moderation tasks by shadowing the actions taken by your Matrix
|
|
Client.
|
|
|
|
- Draupnir synchonises bans for users, and servers across all of the matrix
|
|
rooms that you moderate
|
|
|
|
- Draupnir can protect your community by applying policies from community
|
|
curated policy lists. For example lists such as the the
|
|
[community moderation effort](https://matrix.to/#/#community-moderation-effort-bl:neko.dev),
|
|
can be watched to protect your rooms around the clock. This means that
|
|
adjacent Matrix communities can warn and protect each other of known threats.
|
|
Draupnir and the list provided by the community moderation effort are the
|
|
bread and butter essentials of moderating public spaces on Matrix.
|
|
|
|
- Draupnir includes a series of
|
|
[protections](https://the-draupnir-project.github.io/draupnir-documentation/protections)
|
|
that can be enabled that can help you in given scenarios when your community
|
|
is being targeted.
|
|
|
|
- Draupnir includes
|
|
[homeserver administrative](https:/the-draupnir-project.github.io/draupnir-documentation/bot/homeserver-administration)
|
|
features, such as reviewing abuse reports, deactivating user accounts and
|
|
shutting down rooms. This also includes protecting your homeserver with
|
|
Draupnir's watched policy rooms.
|
|
|
|
- Draupnir is primarily a room moderation bot and can be used with or without
|
|
server administrative capabilities.
|
|
|
|
- **Draupnir is a forwards and backwards compatible drop in replacement for
|
|
[Mjolnir](https://github.com/matrix-org/mjolnir)**.
|
|
|
|
### Prompt UX
|
|
|
|
The main difference from Mjolnir is that it is no longer necessary to use
|
|
commands for some functions. Banning a user in a protected room from your Matrix
|
|
client will cause Draupnir to show a prompt in the management room, which will
|
|
offer to add the ban to a policy list[^the-gif-width].
|
|
|
|

|
|
|
|
You can also unban users the same way, and Draupnir will prompt you to unban
|
|
them without any confusing hiccups. If you do still wish to use the ban command,
|
|
please note that users and other entities that are being banned are now the
|
|
first argument to the ban command. It is now also possible to provide only the
|
|
entity to Draupnir and have Draupnir prompt you for the policy list and the ban
|
|
reason.
|
|
|
|

|
|
|
|
In general, all commands have been migrated to a new interface which feature
|
|
better error messages for common problems and allow admins to trace the cause of
|
|
unexpected errors much more easily.
|
|
|
|
[^the-gif-width]:
|
|
Yes, i know they don't align horizontally, you are welcome to suggest how
|
|
this should be fixed.
|
|
|
|
### Technical differences from Mjolnir and other moderation bots
|
|
|
|
> I offer you the ring, which was burned, laid upon the pyre of Baldr by Odin.
|
|
|
|
Draupnir started as a fork of [Mjolnir](https://github.com/matrix-org/mjolnir),
|
|
in order to radically refactor the code base and break a feature freeze.
|
|
Draupnir has now completed this refactor and large sections of the the code base
|
|
are now very distinct, as much of Draupnir was rewritten.
|
|
|
|
**Draupnir remains a forwards and backwards compatible drop in replacement for
|
|
Mjolnir**.
|
|
|
|
- Draupnir is much less dependant on commands and will automatically send
|
|
prompts to the management room. Prompts are sent for inviting Draupnir to
|
|
protect rooms, watch policy lists, ban users, and unban users.
|
|
|
|
- Draupnir is much more responsive. Unlike Mjolnir and other bots, Draupnir does
|
|
not need to request any data from the homeserver before applying new bans or
|
|
to ban new users.
|
|
|
|
- Draupnir uses an advanced persistent revision system for room state, members,
|
|
policies, and policy matches. By using revisions, Draupnir only has to process
|
|
room state once in terms of simple deltas as room state is updated.
|
|
|
|
- Draupnir offers a
|
|
[room state backing store](https://github.com/the-draupnir-project/Draupnir/blob/69b666e56d89472c05175685267b333a7ab988fe/config/default.yaml#L186-L192),
|
|
allowing Draupnir to startup quickly, even when deployed at distance from the
|
|
homeserver.
|
|
|
|
- Draupnir's core functionality is implemented as protections, which can be
|
|
configured and dynamically turned on and off. If you can write even a little
|
|
JS/TS, Draupnir's behaviour can be radically changed or customized. And
|
|
because the core functionality is implemented with the extension system, there
|
|
are less limits.
|
|
|
|
- A huge effort has been spent refactoring the code base, paving the way for
|
|
future feature development of Draupnir and adjacent projects. This includes
|
|
the rewrite of the core of Draupnir into the
|
|
[matrix-protection-suite](https://github.com/Gnuxie/matrix-protection-suite),
|
|
providing all the Matrix client code required to operate a protection
|
|
platform. The matrix-protection-suite also covers severall shortfalls in the
|
|
available SDK's, providing event parsing and types that keep code secure and
|
|
sound. The
|
|
[interface-manager](https://github.com/the-draupnir-project/interface-manager)
|
|
providing an advanced command-oriented interface (note, this does not mean
|
|
command-line interface). The
|
|
[matrix-basic-types](https://github.com/the-draupnir-project/matrix-basic-types)
|
|
library for dealing with Matrix's various string types. And finally the
|
|
introduction of [prettier](https://prettier.io/),
|
|
[eslint](https://eslint.org/) and
|
|
[typescript-eslint](https://typescript-eslint.io/) into Draupnir's development
|
|
tooling, modernising TypeScript development.
|
|
|
|
## Status
|
|
|
|
Draupnir is being supported with a grant from NLnet, the goals of the work are
|
|
described [here](https://marewolf.me/posts/draupnir/24-nlnet-goals.html)
|
|
|
|
Currently The UX and code base of Draupnir has been overhauled and we have
|
|
recently passed a huge milestone: Draupnir's 2.0.0 release.
|
|
|
|
### Migration
|
|
|
|
Migrating from Mjolnir is straightforward and requires no manual steps,
|
|
migration for your setup is likely as simple as changing your server config to
|
|
pull the latest Draupnir docker image instead of a mjolnir one. Draupnir remains
|
|
backwards compatible so that it is possible to try Draupnir and still have the
|
|
option to switch back to Mjolnir.
|
|
|
|
Any problems with migration should be reported to our
|
|
[support room](https://matrix.to/#/#draupnir:matrix.org).
|
|
|
|
## Setting up
|
|
|
|
See the
|
|
[setup documentation](https://the-draupnir-project.github.io/draupnir-documentation/bot/setup)
|
|
for first-time setup documentation.
|
|
|
|
See the [configuration sample with documentation](config/default.yaml) for
|
|
detailed information about Draupnir's configuration.
|
|
|
|
See
|
|
[homeserver administration](https://the-draupnir-project.github.io/draupnir-documentation/bot/homeserver-administration)
|
|
for how to use Draupnir's features to protect your homeserver and users.
|
|
|
|
## Quickstart guide
|
|
|
|
After your bot is up and running, you'll want to run a couple commands to get
|
|
everything set up:
|
|
|
|
1. `!draupnir list create my-coc code-of-conduct-ban-list` - This will create a
|
|
new ban list with the shortcode `my-coc` and an alias of
|
|
`#code-of-conduct-ban-list:example.org`. You will be invited to the room it
|
|
creates automatically where you can change settings such as the visibility of
|
|
the room.
|
|
2. Review the
|
|
[Moderator's Guide](https://the-draupnir-project.github.io/draupnir-documentation/moderator/setting-up-and-configuring).
|
|
3. Review `!draupnir help` to see what else the bot can do.
|
|
|
|
## Legacy documentation (`v1.87.0` and below)
|
|
|
|
For information about the legacy version of Draupnir, see `v1.87.0`, the
|
|
documentation for which can be found
|
|
[here](https://github.com/the-draupnir-project/Draupnir/tree/v1.87.0).
|
|
|
|
## Contributing & Opening Issues
|
|
|
|
Draupnir wants to be yours as much as it is ours. Please see or
|
|
[contributing document](https://the-draupnir-project.github.io/draupnir-documentation/contributing),
|
|
but do not worry too much about following the guidance to the letter. And keep
|
|
that in mind throughout.
