Only build attributes not found in any cache.

https://github.com/Mic92/nix-build-uncached it is. Even if your flag lands in Nix it is still going to take a while until it ends in a released version. Until than nix-build-cached will pay the builds.

Similar idea for upstream NixOS/nix#3428

[Mic92]

Once there would be a wrapper around nix-build, error logging could be improved as well. Right now it nix-build is quite verbose and it is hard to search for the error that broke a particular package because the build log is quite mix of all builds. It would be better if there was a nix build output that would just iterate over full logs of each failed package individually at the end of execution.

This should probably be a wrapper or (I prefer) part of nix-build. Either way I'll leave it open here since it's relevant.

[Mic92]

This is wrapper I came up with: https://github.com/Mic92/ci-nix-build
It's a single static binary (2mb). Still look for a better name.

Nice! :)

I think it's going to be tricky to get argument passing to nix-build to work, but it's quite nice for 90% of the cases where nix-build does the job.

[Mic92]

I will add support for some build arguments later.

nice! I have a name suggestion: nix-build-uncached. I started adding a nix-build --uncached attribute to Nix itself but this is still at a very early stage.
