PATH of home manager profile is still first with suffix-path=false

[dwinkler1]

I set suffix-path = false here but the path to my global home-manager packages still comes first (this is nix darwin). Am I doing it wrong? Anything I can do to prefix?

> $ echo $PATH

This... Might be a bug? What you did should work. The setting is being accurately reflected in NixCats settings output. So you did it correctly. Let me double check real quick. Edit: no it seems to be working for me actually, I set suffix-path = false and now all my stuff is first (but only within nvim)

Are you echoing the path from within the nvim terminal? The path is only modified inside of nvim.

Ha in fact the nix profile path is there twice which makes me think it gets added again after nixCats sets the path:

I am running this with nix run . in the directory with the flake. Could this be a problem?

It shouldn't be, that's what I just did to test it.

Very strange, yes I am showing the path within nvim and the /nix/store/... paths are only there in nvim. They get prefixed with respect to the MacOS paths (e.g., homebrew) but not the home manager ones.

very strange indeed. Because this means that nixCats is correctly passing --prefix option to makeWrapper, and yet makeWrapper seems to not be prefixing it correctly on macos.

What nixCats does is create a wrapper script via pkgs.makeWrapper, which you launch instead of nvim itself. The wrapper script directly prefixes or suffixes the variable.

You can see the logic for prefix vs suffix here

parsing function

call site for said function

Thats the only thing that I could think would be causing it yeah

Very weird.

That doesnt seem to be the case on linux though? Im unsure why mac home manager would be adding itself a second time after starting nvim

Are you doing :echo $PATH or are you doing :term and then echo $PATH? Maybe your shell config adds home manager paths when the shell is started by :term?

I think the culprit is the determinate nix installer: DeterminateSystems/nix-installer#782
Thank you so much for your help! If this persists I'll install nix directly without determinate.

edit: updating determinate to the newest seems to fix it

[BirdeeHub]

yay glad you were able to diagnose it!

That was a weird one!

[BirdeeHub]

Oh, also, if you don't want to set it for all values and would like particular ones to be prefixed and others to be suffixed, you can set it on an individual basis by putting { pre = true; value = pkgs.thepackage; } or { pre = false; value = pkgs.thepackage; } instead of just pkgs.thepackage

This works for both lspsAndRuntimeDeps and sharedLibraries sections.

suffix-path and suffix-LD set the default behavior, and then for individual, there is the above.

[dwinkler1]

That is awesome!
