@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
@lillecarl:matrix.orgLilleCarl (Salsa9)https://github.com/water-sucks/optnix Haha sry i forgot to link the most essential thing! 😄19:14:28

{ lib

}:
# $FLAKE should be configured to where your repository is located
# Preferably using direnv, you can also set it into your sessionVariables
let
  dot_path = "${builtins.getEnv("FLAKE")}/sub/dir/";
  dot_paths = lib.filesystem.listFilesRecursive dot_path;
  dot_strings = builtins.map (x: builtins.toString x) dot_paths;
  dot_prefixDeleted = builtins.map (x: builtins.replaceStrings [ dot_path ] [ "" ] x) dot_strings;
  dotfile_outOfStoreLinked = lib.attrsets.genAttrs dot_prefixDeleted (name: {
    source = config.lib.file.mkOutOfStoreSymlink (dot_path + name);
  });
in
{
  home.file = dotfile_outOfStoreLinked;
}

I know I mentioned linking things from $FLAKE repo into $HOME which I'm quite happy with. This is the implementation I'm using. It'll replicate a tree subdir into $HOME for you, nothing using home.file.x.recursive so you won't get collisions with folders and stuff 😄

@claesatwork:matrix.orgClaesI didn't know you could do that! 22:36:07

@igorramazanov:matrix.orgigorramazanovWould be nice to have an additional option: "does not really matter" and also allow multichoice19:51:29

Will do it in the next iteration. I'm still exploring the options that matrix provides.

@markuskowa:matrix.orgmarkuskowaIt looks like there is a slight preference for Wednesday. Should we go with Wednesday the 21st?09:58:19
13 Feb 2024
@markuskowa:matrix.orgmarkuskowaOk, let's have the next meetup, on Wednesday 21.02. Same place, same time (19:00 at the Nordic light hotel).21:02:15
21 Feb 2024
@markuskowa:matrix.orgmarkuskowaSee you tonight. 09:47:33
@claesatwork:matrix.orgClaesHi, I told some of you about my home audio setup. I created a gist with most of it here https://gist.github.com/claes/61d0579df00a205385b5bd3ed235132c21:52:31

ah this was what you were talking about yesterday! i'm gonna try to roll with some variant of this for a while. long time ago any of my systems were impure hehe
19:05:22
@kraem:ne.bul.aekraem LilleCarl (Salsa9): also did you mean https://github.com/PRQL/prql ? in that case we thought about the same project 19:06:26

Yeah there's the fileset lib I didn't even know about until i saw "umport" that recursively imports modules 😄 So it can be "nicer"

Yeap, along with for running prql within pg https://github.com/kaspermarstal/plprql
19:09:19
@lillecarl:matrix.orgLilleCarl (Salsa9)It's early work, but it's nice to see either way. SQL has had it's best days19:10:06
@kraem:ne.bul.aekraemyeah i saw that, nice! last time i checked prql i think they were still talking about implementing the postgres layer19:10:12
@kraem:ne.bul.aekraemthis (https://github.com/neondatabase/neon) is pretty interesting as well, although not the same thing at all. it basically swaps out the storage layer of postgres, making it distributed and the backing storage is s3 :)19:24:28
