Not sure if it's the right place to ask this. I've never used NixOS but I'm interested in doing so for dev. Is it possible possible to install Jetbrains IDE on NixOs and use it as I would with a regular distro? I'm not directly looking into leveraging nix shell etc. From what I've been reading online it's not supported. I like the idea behind nix and the idea of reverting to a previous *working* configuration is the main reason I'm looking to switch.

So I'm on nixos-unstable and I'm trying to update my system, but the package gnome-decoder is marked as broken and halts the build. A fix has been pushed to master, but hasn't hit nixos-unstable yet.

I've set environment.gnome.excludePackages = [pkgs.gnome-decoder] and have no references to the package anywhere else, but it still somehow keeps being added to my system, and I have no idea why or where. I've looked through the linked file in the NixOS package search, and it doesn't reference the package. GitHub search on the nixpkgs repo only shows commits and no code references to the package.

Here's the file on the commit fixing the package: https://github.com/NixOS/nixpkgs/blob/bcf8849a8144cd2dde13784e3de04d9b1e27cfb6/pkgs/applications/graphics/gnome-decoder/default.nix

Any idea what options enable this?

I'm attempting to make an overlay, but I'm a noob with all the override methods and the package doesn't call stdenv.mkDerivation, but clangStdenv.mkDerivation, so I'm not sure how to make this work. My attempts so far have yielded errors with fixed-points, missing arguments, or wiping out the other packages in nixpkgs

final: prev: { gnome-decoder = prev.gnome-decoder.overrideAttrs (attrs: { preBuild = ...; }); } should work asan overlay

GNOME decoder is not installed by GNOME NixOS module so excludePackages will not work. In fact it is not really installed by anything by default. Are you sure you are not adding it somewhere?

In reply to @jtojnar:matrix.org
you can use --show-trace to find the call chain

I use this, but the output I get is almost always entirely comprised of a super long call chain through some libs/builtins and an entrypoint I already knew was part of the fault, but not enough context about scoping & option values to diagnose why that entrypoint is broken.

I'm new to functional stuff in any real capacity outside of some scheme for a college course, are these long call traces thru external code useful? I usually only can really follow a frame or two of it before it becomes basically a black box.
