nixos-vars: nixos-vars: - fix naming inconsistencies (run & script, "backendModule" not being nixos-vars: clear enough (is it a generator or a prompt backend?) etc) nixos-vars: - make jsonify idempotent nixos-vars: - make jsonify accept both target and host nixpkgs instances, reusing nixos-vars: the one the given NixOS config has been built with in case none has been nixos-vars: given Signed-off-by: prescientmoon <git@moonythm.dev>

nixos-vars: nixos-vars: It was confusing, since the name doesn't specify whether the override nixos-vars: applies to the host or target instance. Will add this back once a clear nixos-vars: usecase appears, as that way I know which one it *should* refer to. Signed-off-by: prescientmoon <git@moonythm.dev>

…error code for the exists script Signed-off-by: prescientmoon <git@moonythm.dev>
nixos-vars: nixos-vars: These work by creating a wrapper script, like discussed last meeting. nixos-vars: This does add a bit of evaluation overhead (as the output store path nixos-vars: must be computed at evaluation time for every such script!), althouh we nixos-vars: make sure not to downgrade the existing cases by checking whether what nixos-vars: we receive is already a derivation or not (if it is, we can move on).

nixos-vars: nixos-vars: Unfortunately, the test requires disabling the Nix sandbox to run, as nixos-vars: internet connectivity is currently a prerequisite for running the CLI. nixos-vars: We'll discuss this in today's meetup. Signed-off-by: prescientmoon <git@moonythm.dev>

- `prompts` are now scoped per-generator - `generators` -> `store` - backends / defaults are scoped more nicely in the NixOS module - prompt.script -> prompt.ask - secret.script -> secret.generate - generator scripts are now optional - a bit more checking of --set and --generate overlaps - json schema validation for the input JSON
…ly been generated
Also fixes `from_jsom` being used instead of `from_json` (typo!)
Also fixes the lack of $prompts when --no-sanbox is used
the tests are failing... will ask for help in today's meetup
fixes a given review comment
This commit adds proper handling of: - added/removed dependencies - failed/canceled prior runs

I've been working on a re-implementation of NixOS vars as part of the Google Summer of Code project, together with my mentor @Lassulus. For info about the API, check the README included with this PR.
Things done
This PR implements a basic CLI for working with vars, a NixOS module that can be used together with the CLI, and some simple examples. There's also a simple NixOS test.
A bunch of concepts in the API have temporary names. Feel free to suggest better ones!
