 elikoga | If you were able you would be able to smuggle information into the evaluation process | 11:07:43 |
| elikoga | Why do you want to access that string? | 11:08:07 |
 cleverca22 | In reply to @elikoga:matrix.org
Why do you want to access that string? i need the path to something in the working tree, to pass to a util i'm running in a shell
i dont want to have to re-load the shell every single time things get modified, thats already caused bugs because this wasnt noticed
i could use the working directory, but then it will fail if you cd into the wrong sub-dir
| 11:54:07 |
| elikoga | I use git rev-parse --show-toplevel in a shellHook in the dev shell and if you run it from outside the repo that's on you | 11:55:42 |
| cleverca22 | ah yes, that sounds perfect | 11:56:48 |
| cleverca22 | i'm also using direnv, so you cant run it from outside the repo | 11:57:19 |
| cleverca22 | the shell would unload all of those utils | 11:57:24 |
| cleverca22 | error: attribute 'self' missing
22| _module.args = {

| 12:01:32 |
| cleverca22 | now that just leaves this puzzle, it was working earlier | 12:01:40 |
| elikoga | I do not know inherit (flake) I've never met this man in my life | 12:02:34 |
| elikoga | Also self is in inputs | 12:02:49 |
| cleverca22 | nix-repl> x = builtins.getFlake (toString ./.);
nix-repl> x.inputs.self

| 12:03:14 |
| cleverca22 | i think i just want flake.outputs | 12:03:55 |
| elikoga | I think you have access from the inside | 12:04:04 |
| elikoga | From the outside you can just toString getFlake to get the path I think | 12:04:25 |
| cleverca22 | in this case, i want one of the outputs on the flake | 12:04:41 |
| cleverca22 | x.outputs.packages.x86_64-linux.netinstall_image so yeah, i just want outputs | 12:05:00 |

| solomon | Hi. is there any way to have nested package outputs like this?
packages = {
foo = pkgs.foo;
bar = {
baz = pkgs.baz;
qux = pkgs.qux;
};
};
| 00:15:10 |
| solomon | so that you can do something like nix build '.#bar.baz' | 00:15:28 |
| solomon | I thought flake-utils' flattenTree would do this but it doesnt seem to | 00:18:23 |
| solomon | * I thought flake-utils' flattenTree would allow this but it doesnt seem to | 00:18:30 |
| elikoga | I think you can place them in the root of the flake outputs | 00:19:01 |
| solomon | what do you mean? | 00:19:16 |
| elikoga | Right now you're trying to use shorthand package selection syntax but it probably fails due to there not being an architecture | 00:19:27 |
| solomon | sorry let me give a real example:
packages = flake-utils.lib.flattenTree {
docker = import ./nix/docker.nix {
inherit pkgs;
cofree-bot = hsPkgs.cofree-bot;
};
ghc982 = flake-utils.lib.flattenTree {
chat-bots = hsPkgs.chat-bots;
chat-bots-contrib = hsPkgs.chat-bots-contrib;
cofree-bot = hsPkgs.cofree-bot;
default = hsPkgs.cofree-bot;
};
chat-bots = hsPkgs.chat-bots;
chat-bots-contrib = hsPkgs.chat-bots-contrib;
cofree-bot = hsPkgs.cofree-bot;
default = hsPkgs.cofree-bot;
};
