Utilities for operating with nix-shell environments

[svenkeidel]

Hi,

independently from this repository, I developed a few utility functions for working with nix-shell environments link. I think these functions could be beneficial for this repository and I would like to merge my work with yours.

The functions include:

• nix-shell-command to compose a nix-shell command string that can be passed to the commandline
• nix-shell that directly executes a command in the given sandbox
• nixos-find-sandbox searches from the given path upwards until it finds a *.nix file.
• nixos-current-sandbox searches from the current working directroy upwards until it finds a *.nix file
• nixos-executable-find, a replacement for the built-in executable-find. It searches in the given sandbox for executables.

Let me know what you think.

Best, Sven

Yeah, looks good to me. Perhaps would could add this to this repo, update the MELPA request to pull in another library, and make you a collaborator?

The only thing I see that this would need (just at first glance) is probably some autoload lines.

Looks good. I may not have time until tomorrow to get to this, but I appreciate you sharing!
