I've made a room with a example bot, if the basic functionality which would be nice. https://matrix.to/#/!dbclAdUzjvAPmXTUom:matrix.org?via=eyjhb.dk&via=matrix.org&via=rend.al , atm..

Has some wiki, packages, options functionality, as well as evaluating nix expressions and defining variables in the evaluated nix expressions. E.g. , wiki = "The official NixOS wiki is located at https://wiki.nixos.org" , followed by , wiki.

Deployment repo (feel free to open issues here): https://github.com/eyJhb/nixbotbot

Bot repo (to be moved into the deployment repo): https://github.com/eyJhb/gomabot

Hopefully there is some interest in this.
