orchid

This program was made to solve the problem resulting from the following sequence of events:

Enter a nix-shell -p $library, where $library is needed for development
In the shell, build some $program, which links with, or makes use of, $library
Exit the shell, run nix-collect-garbage
$program now lacks $library and breaks

Orchid scans the given paths for references to the nix store and pins whatever it finds.

In other words, it makes nix take roots outside of the store+environments, hence the name.

Other nice features are:

Installation

Both a traditional default.nix and a flake are provided. Install from a checkout with:

$ nix-env -f . -i

or:

nix profile add

To scan PATH for references and pin them, run

orchid pin PATH

Use the --help flag to see more options.
