WeeChat

WeeChat is a fast and extensible IRC client.

Basic Usage

By default, the module creates a systemd unit which runs the chat client in a detached screen session.

This can be done by enabling the weechat service:

{ ... }:

{
  services.weechat.enable = true;
}

The service is managed by a dedicated user named weechat in the state directory /var/lib/weechat.

Re-attaching to WeeChat

WeeChat runs in a screen session owned by a dedicated user. To explicitly allow your another user to attach to this session, the screenrc needs to be tweaked by adding multiuser support:

{
  programs.screen.screenrc = ''
    multiuser on
    acladd normal_user
  '';
}

Now, the session can be re-attached like this:

screen -x weechat/weechat-screen

The session name can be changed using services.weechat.sessionName.
