nickel VS AppImageKit

So, its key features are:

1. domain-specific: designed for conveniently creating and composing derivations. This reason alone already justifies a new language, or an embedded domain-specific language (such as the Guile/Scheme for guix), or a mix of both (Starlark, the build language of Bazel embedded in a restricted Python-variant).

2. purely functional: this ties well into the philosophical backing of Nix the package manager, which aims to be purely functional, also known as hermeticity in other build systems (Bazel).

3. lazily evaluated: similar to other build systems (including Bazel), so that you can build only what you need on demand.

4. dynamically typed: this one is controversial. Being dynamically typed—in other words, not developing a type system—gets Nix out of the door first. But users often complain about the lack of proper types and modularity. There are experiments to address this, such as Nickel (https://github.com/tweag/nickel).

It is understandable that a one-pager may not have space for the whys.

Nickel：Nickel is a straightforward configuration language aimed at automatically generating static configuration files. Essentially, it's akin to JSON with the addition of functions and types.

Also look at nickel which is an evolution of nix. It's my favorite in this space.

Nickel is a programming language. While HCL is just a configuration format, so not really comparable.

Here's a comparison with similar tools: https://github.com/tweag/nickel#comparison

As for 'providence', I suppose you meant provenance :) it's been delayed because this was less critical for 1.0 to decide on or to implement (as it: it doesn't break backward compatibility in any way to add this feature in the short term), but this is very much on the roadmap: Issue #235. That's a must-have in a language with merging like Nickel.

Have you considered using a different language for templating? this could be a BIG selling point. Some good ones are cue-lang (though I haven't seen support for rust), kcl or nickel-lang.

What you're looking for sounds like AppImages (https://appimage.org/) . I have only used them while downloading games from itch.io, etc. (since i prefer package managers) but they seem to work out of the box on popular distros.

Ideally a new instance of the application is installed for each user. This also provides better isolation if one user upgrades/removes/breaks their application instance. I, for one, have really come around to the AppImage model [0] in the last couple of years.

I found a similar issue on github and tried this solution but still getting the same error .

There is AppImage[1], which packs a lot of stuff into a SquashFS filesystem, appends it to the executable, so everything is in one file.

Nah i think yall just hating appimage. Real gold standard.

Although I haven't used plugins feature myself yet, this does sound like the perfect use case for them. Not every patient needs to access every single source. With plugins you can load only the source (or few sources) that they actually need. You can still use something like https://appimage.org/ to give them "a single binary", but will actually contain your slim binary and all the plugins.

```dlopen(): error loading libfuse.so.2 AppImages require FUSE to run. You might still be able to extract the contents of this AppImage if you run it with the --appimage-extract option. See https://github.com/AppImage/AppImageKit/wiki/FUSE for more information```

This doesn't look like a squashfs image. Cannot mount AppImage, please check your FUSE setup. You might still be able to extract the contents of this AppImage  if you run it with the --appimage-extract option.  See https://github.com/AppImage/AppImageKit/wiki/FUSE  for more information open dir error: No such file or directory

appimages. Appimages are similar to flatpaks, exept that they are a file you download and double click to run. Think of them as portable softwares like windows has (portable apps). They are sandboxed too. You can learn more about appimages here
