New experimental nixvim configurations fail without devshell input

Can you share a minimal reproducible example?

Do you still have inf-recursion if you use config instead of self'?

Yes

[HeitorAugustoLN]

Maybe this could help: https://flake.parts/dogfood-a-reusable-module? As in the flake-parts documentation says it helps to avoid infinite recursion, but haven't looked into it too see if it this would help in this case.

[MattSturgeon]

Thanks. I have read that a few times, but re-reading it never hurts 🧐

The inf-recursion discussed there would be relevant if our flake-modules depended on something else from nixvim's flake outputs. However IIRC the modules are self contained.

For reference, @khaneliman has been successfully using the modules in his flake: khaneliman/khanelivim#12. It'd be interesting to see what's different between yours and his implementations.

[HeitorAugustoLN]

In my neovim configuration, it is working fine currently, with the new experimental configurations. I just can't remove the devshell input specifically from the nixvim inputs as I used to before.

[HeitorAugustoLN]

Okay, nevermind, it is not specific to devshell, it also happens when removing git-hooks and treefmt-nix.

[MattSturgeon]

[it] happens when removing [nixvim's optional flake inputs]

Ah, gotcha. I missed that detail at first.

I'll try and find time to investigate. Otherwise remind me in a few days.
