Set haddock URLs to hackage

[GuillaumeDesforges]

I'm building documentation with nix-build -A mypackage.components.library.doc

However that give me html pages with links to other packages like: file:///nix/store/94lvmc6196dp2blza38jh21sqbm4dzzs-basement-lib-basement-0.0.11-haddock-doc/share/doc/basement/html/Basement-Compat-Base.html#t:IO

Could I set to use some other URLs like described here?

I think the current behavior is definitely the correct default; I actually really like that I can get my own local universe of packages complete with Hoogle, all accessible locally. You can even do hoogle server --local and serve your whole project's closure to an internal network.

Sorry if I was not clear. It is good that we can access the doc locally, but I believe that being able to export the doc is also necessary.
If I have to use haddock outside of haskell.nix, then I loose all the benefits of the haskell.nix infrastructure.

So I suggest adding such a feature.

In the end I wrote a doc.nix

let
    pkgs = import ./nixpkgs.nix {};

    base = import ./default.nix;
    base-doc = base.mypackage.components.library.doc;
in
    pkgs.runCommand
        "${base-doc.name}-url-corrected"
        { }
        ''
            cp -R ${base-doc}/* $out
            find $out -exec chmod 755 {} \;
            find $out -type f \
                -exec sed -i -e \
                    "s/file:\/\/\/nix\/store\/[a-z0-9]\+.\+-lib-\(.\+\)-\([0-9\.-]\+\)-haddock-doc\/share\/doc\/\(.\+\)\/html\//https:\/\/hackage.haskell.org\/package\/\1-\2\/docs\//g" \
                    {} \;
        ''
