Override input throws .devenv.flake.nix not found

[dejanr]

Having a non flake input, and trying to override it via --override-input throws an error:

λ devenv build --override-input non-flake "git+file://home/../non-flake"
error:
       … while updating the lock file of flake 'git+file:///project'

       … while updating the flake input 'non-flake'

       error:
       error: '/project/non-flake/.devenv.flake.nix' does not exist
Error:   × Command `/nix/store/f0yj40kxp6b92vf6nbmg7bgr1cdhymrm-nix-2.24-devenv/bin/nix --show-trace

Not really sure if this should work. Grateful if someone could show me a working example of override-input.

My use case is that i have a repo as an input, and while working locally i want to override that input with local copy of that repo, so that i could work easily on up-streaming some changes to input dependency repo.

Yeah, we use input overrides all the time. I normally use path:, though I guess this also works.

We need to narrow down this issue. What have you already tried? Have you tried using the url in devenv.yaml directly (without the override)? Have you set flake: false for this input?

I tried all 'path:', 'git+file', we are moving this repo to flake soon, but it might be a show stopper for someone else.

Yes, i use flake: false for that input, looking at nix eval eval --json .#build is still being called, so we either have to allow passing flake false or read this from input?
