nix-gui VS dhall-lang

This is pretty close https://github.com/nix-gui/nix-gui

Nix based aiming at beginners. If it combines/works with https://github.com/nix-gui/nix-gui, then an amazing distro may be created. It would be user friendly, but also extremely powerful, allowing basically everything to be configured via the gui. Both softwares are alpha state, but I am excited to see what they bring.

Maybe https://github.com/nix-gui/nix-gui? I dunno if it can do userspace config though.

Would it make sense to integrate something like nix gui into this?

I remember when I first started using NixOS, as a confused beginner I tried to find a graphical application to manage and edit my configuration. I stumbled upon Nix-Gui, however, I didn’t really like the look, it crashed a fair amount, and I never really figured out how to use it. That said, their idea and all of the hard work they put into their project inspired me to make a similar application that focuses more on simplicity and ease of use.

I was wondering if you are aware of https://github.com/nix-gui/nix-gui and how your tool compares to it

There is also a GUI in development, hopefully it will help casual users in the future.

There's https://github.com/nix-gui/nix-gui for a gui like experience.

Configuration language usage: Probably a major win for programmers, but a major negative for non-programmers. However, nix-gui has shown that there's potential for gui-based nixos configuration. And this might one day be extended to use as part of the graphical installer. https://discourse.nixos.org/t/why-is-there-no-installer-for-nixos/16644/21. Since nix can be serialized and deserialized to json, there's actually a fair amount of interoperability able to be done to manipulate nix configuration using existing libraries.

Fail to see how this is any different than Dhall (https://dhall-lang.org/) other than it produces plists too.

Kubernetes config is a decent example. I had ChatGPT generate a representative silly example -- the content doesn't matter so much as the structure:

https://gist.github.com/cstrahan/528b00cd5c3a22e3d8f057bb1a7...

Now consider 100s (if not 1000s) of such files.

I haven't given Pkl an in depth look yet, but I can say that the Industry Standard™ of "simple YAML" + string substitution (with delicate, error prone indentation -- since YAML is indentation sensitive) is easily beat by any of:

- https://jsonnet.org/

- https://nickel-lang.org/

- https://nixos.org/manual/nix/stable/language/index.html

- https://dhall-lang.org/

- (insert many more here, probably including Pkl)

There are underpowered languages / tools, that can only solve a problem for which they are intended poorly. But not all limited tools are like that.

Say, eBPF is prominently not Turing-complete, which allows to guarantee that a eBPF program terminates, and even how soon. Still eBPF is hugely useful in its area.

Or, say, regular expressions are limited to regular languages; in particular, they famously [1] cannot process recursive structures, like trees. Still tools like grep / ag / rg are mightily useful.

Yes, I agree that YAML is underpowered for proper k8s configuration! But it's also too powerful for its own good in other aspects [2]. I wish Google used Dhall [3] or their own purely functional config language (FCL? I already forgot the name) instead of YAML; sadly, they did not.

Dhall: Dhall is a programmable configuration language that combines features like JSON, functions, types, and import capabilities. Its style leans towards functional programming, so if you're familiar with functional-style languages such as Haskell, you might find Dhall to be quite intuitive.

I've been thinking along these lines but more 'strongly validated' than statically typed in the sense that you'd be better off being able to load the entire config and then produce a list of problems (and should be able to offer good editor support if done correctly).

Though https://dhall-lang.org/ demonstrates that you can statically type quite a lot of configuration to great advantage, which appears to be programmatically embeddable in multiple languages per https://docs.dhall-lang.org/howtos/How-to-integrate-Dhall.ht...

Configuration processing. E.g. I'd like my yamls to be decidable, though I'd settle for guaranteed to halt[1].

Maybe you'd like jsonnet: https://jsonnet.org/

I find it particularly useful for configurations that often have repeated boilerplate, like ansible playbooks or deploying a bunch of "similar-but" services to kubernetes (with https://tanka.dev).

Dhall is also quite interesting, with some tradeoffs: https://dhall-lang.org/

A few years ago I did a small comparison by re-implementing one of my simpler ansible playbooks: https://github.com/retzkek/ansible-dhall-jsonnet
