Special builders

Do I really have to build my $LANG application by hand?

No

Remember build-support ?

• Commonly used languages have specific build support in nixpkgs
• Pros: each builder can handle special cases
• Cons: each builder handles special cases

Rust builder

rustPlatform.buildRustPackage rec {
  pname = "bat";
  version = "0.22.1";

  src = fetchFromGitHub {
    owner = "sharkdp";
    repo = pname;
    rev = "v${version}";
    sha256 = "sha256-ye6GH4pcI9h1CNpobUzfJ+2WlqJ98saCdD77AtSGafg=";
  };

  cargoSha256 = "sha256-ye6GH4pcI9h1CNpobUzfJ+2WlqJ98saCdD77AtSGafg=";

  ...
}

Go builder

buildGoModule rec {
  pname = "dive";
  version = "0.10.0";

  src = fetchFromGitHub {
    owner = "wagoodman";
    repo = pname;
    rev = "v${version}";
    sha256 = "sha256-1pmw8pUlek5FlI1oAuvLSqDow7hw5rw86DRDZ7pFAmA=";
  };

  vendorSha256 = "sha256-YPkEei7d7mXP+5FhooNoMDARQLosH2fdSaLXGZ5C27o=";
}

Python builder

buildPythonPackage rec {
  version = "0.7.5";
  pname = "pickleshare";

  src = fetchPypi {
    inherit pname version;
    sha256 = "87683d47965c1da65cdacaf31c8441d12b8044cdec9aca500cd78fc2c683afca";
  };
}

Not all specific builders are defined in build-support (that would be too boring).

But a lot of them are.
