The doc expressions take both a pkgs packageset as well as a nixpkgs argument whose purpose is unclear.

I traced all the usage of nixpkgs and it appears to be simply "any attrset with a revision attribute". Let's replace this argument with nixpkgs-revision so people know what its purpose is.

I did not change the arguments to doc/default.nix because it might
be considered an exposed public interface (does Hydra
nix-instantiate it directly?). We should give it an entry in
all-packages.nix and access it that way.

The `doc` expressions take both a `pkgs` packageset as well as a
`nixpkgs` argument whose purpose is unclear.

That's probably the right thing to do, but I don't feel qualified to call that shot alone.

@pennae @roberth 👍 👎 ?

is this even necessary after #226057? looks like both achieve the same thing.

Does this work with [nixpkgs]$ nix-build ./doc?

No, it doesn't.

I guess there's some ambiguity about what are valid entry points into nixpkgs. Maybe this should wait until that question gets answered.

Keeping nixpkgs around as a convenience method seems like a good thing, but I agree that these functions have no business depending on a whole flake, if that's what you're going for. Not sure how useful such interface segregation is, in this instance.

That was sort of the idea. I wanted to make the manual callable from situations where you really shouldn't assume the ability to import <nixpkgs> (i.e. from top-level/all-packages.nix).

It turned out that the docs don't use that argument for anything except the revision, so the idea was to pass only that.
