Groups for Pleroma!!!

and Mastodon or anything with the Mastodon API.

Usage

Building

Install the rust toolchain using rustup: https://www.rust-lang.org/tools/install

Rust 1.54+ is recommended.

Build with cargo build, or optimized: cargo build --release. The binary is placed in the target/debug or target/release directory.

You can also run the program using Cargo, that is handy for development: cargo run. When passing command line flags, use --: cargo run -- -i my@group.xyz.

Setting up a group account

Create the group's account all nice like you want it. Pleroma and Mastodon should work, others may work too but you're on your own.
Run the group service with fedigroups -a mygroup@groups.social (your account's handle) to authenticate.
Make sure you auth as the correct user!
Paste the Oauth2 token you got into the terminal, hit enter.

The program now ends. The credentials are saved in a file groups.json.

You can repeat this for any number of groups.

Editing config

Do not edit the config while the group service is running, it will overwrite your changes!

The JSON file is easily editable, you can e.g. add yourself as an admin (use the e-mail format, e.g. piggo@piggo.space). The file format is quite self-explanatory.

{
  "groups": {
    "group@myserver.xyz": {
      "enabled": true,
      "acct": "group@myserver.xyz",
      "appdata": {
        "base": "https://myserver.xyz",
        "client_id": "...",
        "client_secret": "...",
        "redirect": "urn:ietf:wg:oauth:2.0:oob",
        "token": "..."
      },
      "admin_users": [
        "admin@myserver.xyz"
      ],
      "member_users": [],
      "banned_users": [],
      "member_only": false,
      "banned_servers": [
        "bad-stuff-here.cc"
      ],
      "last_notif_ts": 1629626621000
    }
  }
}

member_users - used if member_only is true, then only members and admins can post to the group
banned_users - can't post or interact with the group service
banned_servers - work like an instance block

Running

To run the group service, simply run it with no arguments. It will read what to do from groups.json.

Note that the file must be writable, it is updated at run-time.

Commands

To share an original post, mention the group user. Posts with commands, and replies, won’t be shared.

Commands are simple text lines you use when mentioning the group user. DMs work well for this. One post can contain multiple commands; the replies will be batched to one response.

Basic commands

/ignore, /i - make the group completely ignore the post
/members, /who - show group members / admins
/boost, /b - boost the replied-to post into the group

For member-only groups

/leave - leave the group

For admins

/announce x - make a public announcement from the rest of the status
/ban x - ban a user or a server. Note that this is only on the service level, the account won't be blocked or muted.
/unban x - lift a ban
/op, /admin user - grant admin rights to the group
/deop, /deadmin user - revoke admin rights
/opengroup - make member-only
/closegroup - make public-access

For admins of private groups

/add user - add a member (use e-mail style address)
/kick, /remove user - kick a member
