@Amir-Ahmad What does your packages.nix
look like?
@lilyball I was trying with this, copied from your comment https://gist.github.com/LnL7/570349866bb69467d0caf5cb175faa74#gistcomment-3372828.
self: super:
# Packages exposed as part of nixpkgs.userPackages
{
inherit (self)
fish tmux
# …
;
}
@Amir-Ahmad Oh I think you probably put this in ~/.config/nixpkgs/overlays/
directly, yes? I suppose I should have elaborated. Your directory structure should look like
~/.config/nixpkgs/overlays/
userPackages/
default.nix
packages.nix
The nested folder name (userPackages
above) doesn't matter, but the two files do need to be nested in a folder, and the main file is default.nix
in this folder.
What this does is it makes userPackages/default.nix
to be the actual overlay, and that in turn imports ./packages.nix
to construct the userPackages
set. By putting both files in the top level overlays folder you instead make them two separate overlays and the packages.nix
file is then trying to overwrite each package with itself, which causes infinite recursion.
@lilyball It's working now! thanks for the explanation 👍
@lilyball thanks for sharing that, looks great. I'm getting an infinite recursion error when trying to use your 2020 version (The older one works fine).
nix-env -f '' -r -iA userPackages
error: infinite recursion encountered, at /home/user/.config/nixpkgs/overlays/packages.nix:4:17
Any idea what could be causing this?
