How to override and build certain package from master/main branch?

Help
28

I was finally able to make even the original untouched main branch to work by looking again on the sops/package.nix file in nixpkgs.

It contained:

postPatch = ''
    substituteInPlace go.mod \
      --replace-fail "go 1.22" "go 1.22.7"
  '';

And now overriding golang to 1.23.0 and using that I was able to make it compile:

nix-build --expr 'with (import <nixpkgs> { });
(sops.override {
  buildGo122Module = args: buildGo123Module ( args // { vendorHash = "sha256-anKhfq3bIV27r/AvvhSSniKUf72gklv8waqRz0lKypQ="; });
}).overrideAttrs {
  src = fetchFromGitHub {
    owner = "getsops";
    repo = "sops";
    rev = "2eb776b01df5df04eee626da3e99e9717fffd9e0";
    hash = "sha256-VB4/DyQoQnV/AAXteJPsD2vbtAilZcJPTCXk2nvUZU8=";
  };
  postPatch = \'\'
    substituteInPlace go.mod \
      --replace-fail "go 1.22" "go 1.23.0"
  \'\';
}'

Seems interesting that the postPatch step worked but running go tidy mod in the preBuild step did not.
