fix(nix-relative-paths): quote relative paths to allow for external sources when trying to use crane with a non local src (eg, not `./.`) we get the error ``` $ nix flake show <...> error: access to absolute path '/Cargo.toml' is forbidden in pure eval mode (use '--impure' to override) (use '--show-trace' to show detailed location information) ``` To fix this, we quote the relative paths so to properly append them to the base path. https://nixos.wiki/wiki/Nix_Expression_Language#Coercing_a_relative_path_with_interpolated_variables_to_an_absolute_path_.28for_imports.29 ## Reproduction flake ``` { description = "Build a cargo project without extra checks"; inputs = { nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable"; crane = { url = "github:ipetkov/crane"; inputs.nixpkgs.follows = "nixpkgs"; }; external-crate-source = { url = "github:ray-kast/empress"; flake = false; }; flake-utils.url = "github:numtide/flake-utils"; }; outputs = { self, nixpkgs, crane, flake-utils, external-crate-source, ... }: flake-utils.lib.eachDefaultSystem (system: let pkgs = nixpkgs.legacyPackages.${system}; test-crate = crane.lib.${system}.buildPackage { src = external-crate-source.outPath; }; in { packages.default = test-crate; }); } ``` 2022-05-09 16:38:16 +03:00			`src = path + "/input";`
