Add supports for new type = "file" locks added in NixOS/nix@5b8c1de. Unfortunately, the hash provided by the lock file is a recursive hash, while fetchurl wants a flat hash. So we have to use a custom fetchurl function using the builtin:fetchurl builder. Hopefully okay just to add compat for this very useful lock type.
Add support for local files in addition to http / https.
so that fetchurl outputs a real path instead of a source, and our hashes match correctly between flake and non-flake. also it looks like fetchTarball can support local files

Is this ready to merge? Would love to be able to use this |

Hi, do you mind squashing all your commits? Then I will cherry-pick the patch into https://github.com/nix-community/flake-compat |

Doesn't this cause use of these inputs to be import-from-derivation? That doesn't seem desirable behaviour. |

The goal here is that we have an ability to develop flake-compat and actually have tests and be able to validate it is correct. This also imports the file input stuff originally written by matthewbauer here: NixOS/flake-compat#44 This bore fruit already in the form of finding a years old bug lying around in Lix: https://git.lix.systems/lix-project/lix/issues/750
