I was just wondering whether anyone might be able to point me to install instructions for nix on macOS 11 versions. I keep getting errors and in the GitHub issues there seems to be no clear solution.
<bierlingm>
I currently have nix and nix-shell installed, each of which are on version 2.3.10.
<bierlingm>
The error I keep getting when trying to enter nix-shell is:
<bierlingm>
```error: getting status of '/Users/moritzbierling/default.nix': No such file or directory```

bierlingm: no, I'm just pointing out that running `nix-shell` with no args and no `default.nix` or `shell.nix`, will correctly result in that error message.

yaymukun1: Derivations can install system or user *.service files into $out/lib/systemd/system or $out/lib/systemd/user respectively. On NixOS, such services can be enabled by adding the derivation to the `systemd.packages` option. This also works for all other unit types, not just services.
<infinisil>
Try building the derivation to see where the .service file ends up, it should be in the one mentioned above
<yaymukun1>
so, I've figured out how to get the file placed in /etc/systemd/system/foo.service thanks to your help. But it's still not showing up in `systemctl list-units` and it's not enabled. What gives? >_<
<yaymukun1>
it looks like enabling the gammastep package adds it as a linked-runtime by default, no extra work needed
<yaymukun1>
will trawl through other people's nix files to see if anyone knows how to enable it. but i've seen a lot of people writing their own .service files

To get a sha256 hash of a new source, you can use the Trust On First Use model: use probably-wrong hash (for example: 0000000000000000000000000000000000000000000000000000), then replace it with the correct hash Nix expected. For inserting 52 0's in vim: <esc>52i0<esc>
<dominikh>
packaging question: a program shells out to script
<dominikh>
okay, next attempt. starting point is https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/search/recoll/default.nix – recoll shells out to various scripts at runtime, some of which are written in perl. these scripts have runtime dependencies on perl modules. these don't work with the current derivation. how would one go about adding these runtime dependencies, so that the perl
<dominikh>
interpreter can find them? e.g. how do I pipe through perlPackages.ImageExifTool?
<coyotechords>
abathur, thank you, in the future what should I search to find things like that?

srhb: yea. It's a rather nasty issue :D
<srhb>
bb_: First advice: Don't -- at least not to start out with. Trying to fight idioms at the start is going to increase the learning curve tenfold :) Second advice: Just have users invoke nix-shell specifying the actual shell.nix path. From there, you can use shellHook to manipulate what happens.

<Miyu-saki>

<angerman>
Miyu-saki: if I find the proper attribute, yes :D
<Miyu-saki>
Ah, I think I get what you mean.
<Miyu-saki>
First idea I'd have would be to override stdenv, but that doesn't work because you won't be finding the other nixpkgs anyway.
<Miyu-saki>
I wonder, is there a way to introspect a derivation's dependencies? Not just inputs, but dependencies.
<Miyu-saki>
On that topic, are inputs even a thing in Nix? Or is that a Nixpkgs thing.
<Miyu-saki>
I think the answer is it's a Nixpkgs thing, but it's not structure-less in Nix either.
<Miyu-saki>
angerman: Actually, I do have an idea. Override stdenv on your main nixpkgs to include `passthru.foo = "thisisaveryuniquestring";` and then grep for drvs which don't include that string.
<Miyu-saki>
That at the very least allows you to identify which derivation doesn't belong.
<angerman>
well I *do* know this doesn't have the right nixpgks I want it to have.
<Miyu-saki>
Wait, I'm a bit confused right now. Are you saying your closure's depending on 2 different nixpkgs, or you just want to figure out what nixpkgs an arbitrary derivation has?
<Miyu-saki>
I'm confused about this reply. > 08:35:39 angerman | Miyu-saki: if I find the proper attribute, yes :D
<Miyu-saki>
s1341_: I doubt you can properly. `buildCommand` overrides the default building mechanism. You can try appending `fixupPhase` in the end though.
<Miyu-saki>
That is, `buildCommand = '' ... \n ... \n fixupPhase'' `
<Miyu-saki>
But IMO, that's somewhat hacky, and I'd rather just go with mkDerivation.
<Rovanion>
Just running `nix-build nixos/tests/prometheus-exporters.nix -A driver` doesn't work. I don't see driver declared in login.nix so I guess its something automatically inherited?

I'm not really sure; I guess--if you don't have the alias, and expansion is enabled, and the shell hook definitely runs via direnv, and the alias is available via nix-shell--it might be running in a subshell or a different shell/process for some reason

someone more familiar with direnv may be able to say something smarter :)

<abathur>
shapr the derivation is marked as broken, you can see https://nixos.org/manual/nixpkgs/stable/#sec-allow-broken for more on allowing broken packages to build; the build log, assuming it breaks, should make it clearer where the break is

I'm not familiar with the very technicals, but `nix eval` may actually still need to compile. Nixpkgs disallows IFD, so that's not the case though.
<matthewcroughan_>
no compilation needs to occur
<Miyu-saki>
There are 2 parts in a nix build, one is instantiation -- to produce a derivations, the next is building -- to produce build artifacts. When you `nix eval` you're doing the latter, and it's basically a hashed dependency tree. I don't know how they calculate the hash specifically though.
<matthewcroughan_>
Miyu-saki: Latter would mean that you are building something, are you sure about that?
<matthewcroughan_>
Former would mean you are producing derivations.
