Fixed-Output Derivation version of flake-compat

This is a fork of flake-compat which uses fetchers from nixpkgs to create fixed-output derivations.

This flake compat fork therefore only works if you have access to a copy of nixpkgs.

Usage

To use, add the following to your flake.nix:

inputs.flake-compat = {
  flake = false;
  url = "github.com:hraban/flake-compat/fixed-output";
};

Afterwards, create a default.nix file containing the following:

# Alternatively, you could lock nixpkgs in your flake.lock and fetch that, if you preferred
{ pkgs ? import <nixpkgs> {} }:
let
  lock = builtins.fromJSON (builtins.readFile ./flake.lock);
  sourceInfo = lock.nodes.flake-compat.locked;
  flake-compat = fetchTarball {
    url = "https://github.com/${sourceInfo.owner}/${sourceInfo.repo}/archive/${sourceInfo.rev}.tar.gz";
    sha256 = sourceInfo.narHash;
  };
  flake = pkgs.callPackage flake-compat { src = ./.; }
in
flake.defaultNix

If you would like a shell.nix file, create one containing the above, replacing defaultNix with shellNix.

Rationale

This fork was created for cl-nix-lite, because of the large amount of inputs, most of them being unnecessary for actual end users of the scope.
