adisbladis d831b947fc Fix go.mod parser for repeated replace directives
Constructs such as
```
replace google.golang.org/grpc => google.golang.org/grpc v1.33.2
replace github.com/gogo/protobuf => github.com/regen-network/protobuf v1.3.3-alpha.regen.1
```

Are perfectly valid and we previously discarded every one but the last of them.

Gomod2nix

Convert applications using Go modules -> Nix

Usage

From the Go project directory execute:

$ gomod2nix

This will create gomod2nix.toml that's used like so

let
  pkgs = import <nixpkgs> {
    overlays = [
      (self: super: {
        buildGoApplication = super.callPackage ./builder { };
      })
    ];
  };
in pkgs.buildGoApplication {
  pname = "gomod2nix-example";
  version = "0.1";
  src = ./.;
  modules = ./gomod2nix.toml;
}

FAQ

Why not continue work on vgo2nix?

Vgo2nix was built on top of the old Nixpkgs build abstraction buildGoPackage, this abstraction was built pre-modules and suffered from some fundamental design issues with modules, such as only allowing a single version of a Go package path inside the same build closure, something that Go itself allows for.

We need a better build abstraction that takes Go modules into account, while remaining import from derivation-free.

Will this be included in Nixpkgs

Yes. Once the API is considered stable.
