Please switch to vendorSha256, this should fix also the CI error.

Oh I see you commented at ryantm/nixpkgs-update#203, I think it'll work out for you if you'd not only rename the variable modSha256 to vendorSha256, but also zero it out before you rerun nix-build.

This works:

@Enteee, personally, I like this PR much more then yours - it's just so much cleaner and regular. I think I've sort of understood now what was your motivation behind the IFD thing, it's just that I didn't catch initially that you tried to push Nix support upstream at juruen/rmapi#78 .

Never the less, I'm still a bit puzzled - almost every Go app that we ship doesn't include default.nix, shell.nix and all of those files, and most people seem happy about it. Even packages which do have these files and naturally are maintained both upstream and downstream by Nixpkgs contributors, are not packaged using IFD hooks such as you want to apply in #74657. Examples: https://github.com/NixOS/nixpkgs/search?q=maintainers.mic92&unscoped_q=maintainers.mic92

I think you'll like the yet unstable feature flakes - NixOS/rfcs#49 . When it'll stabilized, it'll be possible to do cool stuff like you tried in #74657 with less workarounds.

@doronbehar Oh nice it works now. I wonder why it gave me an empty output before (even though the build log appeared to get all the dependencies and actually compile it). Nonetheless I've updated it so i think it ought to be good to go
