python312Packages.google-cloud-documentai: init at 3.1.0

[AdrienLemaire]

Newbie learning NixOS and how to submit a new package.
I'm not sure how to test it in local given there's a generator to build this package for different python versions.

Things done

• Built on platform(s)
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin
  • aarch64-darwin
• For non-Linux: Is sandboxing enabled in nix.conf? (See Nix manual)
  • sandbox = relaxed
  • sandbox = true
• Tested, as applicable:
  • NixOS test(s) (look inside nixos/tests)
  • and/or package tests
  • or, for functions and "core" functionality, tests in lib/tests or pkgs/test
  • made sure NixOS tests are linked to the relevant packages
• Tested compilation of all packages that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review rev HEAD". Note: all changes have to be committed, also see nixpkgs-review usage
• Tested basic functionality of all binary files (usually in ./result/bin/)
• 25.05 Release Notes (or backporting 24.11 and 25.05 Release notes)
  • (Package updates) Added a release notes entry if the change is major or breaking
  • (Module updates) Added a release notes entry if the change is significant
  • (Module addition) Added a release notes entry if adding a new NixOS module
• Fits CONTRIBUTING.md.

Suggested change

	hash = "sha256-7b156175efe99cc4faafc81beefe4a7867fd54b827ba5ca40c7e8f7d9cd4b525";
	hash = "";

It's better to use the sri hash, you can find it from the error message of the build

Thanks for the review @aucub, I tried to fix most of them.

Still unsure about this one though, here's what I tried:

       error: invalid SRI hash '0q4zallgs8l0yc0ipw5zfha1czw682yxw1azlkirdnj3afw59f3r'

Not sure if I got the wrong hash or the wrong way to build the package.

[aucub]

hash = "sha256-exVhde/pnMT6r8gb7v5KeGf9VLgnulykDH6PfZzUtSU=";

[AdrienLemaire]

Indeed. Thank you.
What command did you run ?

[aucub]

When using nix build, you can typically leave hash = ""; empty. The actual hash will be provided in the error message. You can then convert the SHA256 hash to an SRI hash using the command: nix hash convert --hash-algo sha256 --to sri.
