[Nix-dev] Importing .narinfo into nix store.

[Kevin Cox]

Hello everyone,

I have been trying to get a cluster of computers set up running Nix and
it has been working really well so far. However I am trying to do
something possible a little strange and was looking for a little help
or suggestions for alternative methods of accomplishing my goal.

I am trying to get a method for downloading the dependencies of a
program and run it. This is similar to `nix-shell` but I want to use
precompiled binaries exclusively instead of downloading a Nix
expression and evaluating it.

I have most of the pieces in place, I can build my program and use nix-
push to generate a binary cache of the program as well as all of its
dependencies. This basically leaves me with a file called hash.narinfo
in my binary cache. I feel like it should be fairly easy to use that
file to pull down all of the dependencies required into the nix store
so that my program can run, however I can't find a way to do this.

`nix-store --import` seems very close but it works on a different input
format that includes all dependencies into a single file. Is there a
similar command that can work with binary caches over the web?

I hope my rambling made sense, and thanks for any suggestions.
