Can we add integrations to Discourse?

Would it be possible, for instance, to integrate the Discourse board with Nix github repos? For instance, in “Nixops: deploy a custom kernel module”, rbrewer123 refered to “Nixops issue #893.” I’d be kind of rad if that could automatically onebox to

github.com/NixOS/nixops

machine configs ignore overlay

I've defined a [nixpkgs overlay](https://nixos.org/nixpkgs/manual/#sec-overlays-…install) but nixops isn't picking it up. I'm using the method where I set `NIX_PATH` / `-I` to `MYDIR` where `MYDIR` contains `MYDIR/nixpkgs-overlays/default.nix` with contents like [these](https://nixos.org/nixpkgs/manual/#sec-overlays-definition). Because [nix searches in `$NIX_PATH/nixpkgs-overlays/default.nix`](https://nixos.org/nixpkgs/manual/#sec-overlays-install) by default, that overlay is picked up. So when I `pkgs = import <nixpkgs> {};`, that `pkgs` contains my overrides. But the `pkgs` passed to machine configs like `machine1 = { pkgs, config, ... }: ...` do NOT get passed my overrides, they get passed an un-overridden nixpkgs. Why is that? I can work around it by setting ```nix machine1 = { pkgs, config, ... }: { nixpkgs.config.packageOverrides = pkgs: (import <nixpkgs> {}); ... } ``` but it seems overlays are supposed to work without doing this manually for every machine.

Is that within the featureset of @discourse?

I think that onebox is only working with full URLs. Do you want to have a look and report back? The source code is available at GitHub - discourse/discourse: A platform for community discussion. Free, open, simple.

I found a couple of related plugins, which might actually be better for the vague use cases I had in mind:

GitHub - discourse/discourse-github-linkback: DEPRECATED: Links github content back to a Discourse forum - which seems to add links to Github issues (and presumably PRs) when they’re mentioned in Discourse topics and vice versa.

GitHub - featheredtoast/hubot-discourse-adapter: Adapter for Discourse - which, I guess, would add a bot like Discobot to Discord, but with Github related commands. My understanding is the hubot is fairly flexible in terms of what it can do, so maybe “@hubot, that PR about the thing” could work?

Sounds good. Especially the discourse-github-linkback plugin, it makes sense to help integrate the conversations between nixpkgs and discourse.

I think for Hubot I would first like to see it connected to our IRC channel(s) and provide some useful functionality before adding it to Discourse.

In either case we would have to go with a self-hosted solution as the hosted version only has a fixed set of plugins available. This would also be useful for importing the old mailing list.
