@lillecarl:matrix.orgLilleCarl (Salsa9)I found a tool that I decided to try yesterday and regret I didn't try earlier. It's called optnix, it's essentially a terminal version of search.nixos.org for options.16:31:54
@lillecarl:matrix.orgLilleCarl (Salsa9)https://asciinema.org/a/cEbCAqfEwt0pOAPBDBVLLLj5b Here's a quick asciinema so you can check it out without installing, and they publish as a simple flake, just nixpkgs as a dependency which is nice. It's really useful when you're developing your own modules since it evaluates your own instance of your options rather than a predefined one. So it makes building option hierarchies and actually using them a lot easier, I bet a lot of you use either search.nixos.org or mynixos.org a bit and this is pretty similar :)16:38:42
@markuskowa:matrix.orgmarkuskowaThat's cool! What's the URL for the flake?16:54:31

@aevl:matrix.orgAndersHi all! Just wondering if there are any companies in Stockholm using the Nix ecosystem? (Would be interested in working at such a company!)14:58:58

I learned how to do a really cursed thing today: edit /nix/store paths

sudo unshare --mount bash -c 'mount -your /nix to /nix'

My goal wasn't to edit storepaths but to hardlink to the store, which requires being on the same mount point (which /nix/store isn't because it's RO bind-mounted over itself)

unshare --mount creates your own mount namespace (ish) where you get a clone of what is already, but you can mount over things without disrupting any other processes.

@markuskowa:matrix.orgmarkuskowaI hope everyone had a great summer. Let's start up the new meetup season on Wednesday the 27th at the Nordic light hotel. Give it a thumbs up if you are planning to join.20:13:26

@ahbk:matrix.orgI use NixOS btw

I was going to try this and saw that the maintainer (water-sucks) has integrated this tool along with other neat stuff in a unified nixos-cli. Its beta though and I got a strange error about mailserver.fqdn not being set, but apart from that it went fine and optnix is indeed very nice to use. Thanks for the tips 🤗

If you're tracking a branch of some kind of repo and don't really care about purity, trust the supply chain and just want to get the latest stuff you can use "fetchTree" in impure evaluation to fetch the the hottest shit out there. By default it uses a 1 hour cache to not fetch every time.

      testFetchTree = builtins.fetchTree {
        type = "github";
        repo = "nixpkgs";
        owner = "NixOS";
        ref = "master";
      };

My understanding from reading github comments and whatnot is that it's using the same paths as flakes use for it's inputs.
