Add package flake

[Ben-PH]

This means that someone using nix can add this to their flake inputs:

    dora-rs = {
      url = "github:dora-rs/dora";
      inputs.nixpkgs.follows = "nixpkgs";
    };

and that allows them to add dora-cli, v0.3.6, as one of the declared packages of the system.

This is the first step towards adding dora to the nix package repo.

Maybe making the step use:

cargo install dora-cli --locked

Might make this file simpler and remove the need to fetch from github, having to copy around binaries.

What do you think?

{ lib, fetchFromGitHub, rustPlatform }:

rustPlatform.buildRustPackage rec {
  pname = "ripgrep";
  version = "12.1.1";

  src = fetchFromGitHub {
    owner = "BurntSushi";
    repo = pname;
    rev = version;
    hash = "sha256-+s5RBC3XSgb8omTbUNLywZnP6jSxZBKSS1BmXOjRF8M=";
  };

  cargoHash = "sha256-jtBw4ahSl88L0iuCXxQgZVm1EcboWRJMNtjxLVTtzts=";

  meta = {
    description = "Fast line-oriented regex search tool, similar to ag and ack";
    homepage = "https://github.com/BurntSushi/ripgrep";
    license = lib.licenses.unlicense;
    maintainers = [ ];
  };
}

I'll give that a try

not a adding the install step means that the system doesn't have access to the binary. I'm not entirely sure why that's the case, as distributing rust binaries is not a rabbit hole I've dived down, but I suspect it relates to the install-from-source instruction where you build a package and add target/release/dora to PATH. I tried just with the install step, and not the build step, but had trouble finding where the dora binary was outputted to. Adding the build step meant it was easily found in target/release/

Maybe making the step use cargo install dora-cli --locked

I'm not exactly sure what you mean by this.

I understand thanks for trying!

I'll merge it in that case as is :)

Thanks a lot :)

[Ben-PH]

I'll put it to the test today, and report back.

I'll also probably need to add some CI/CD stuff to make sure that the nix-install approach works.

Thanks for the merge :)
