nix-update VS nix-bundle

You should instead use the regular fetchGit, fetchFromGitHub etc. fetchers in fairly vanilla code, and yes, that often means dealing with checksums in some form. If you truly just want to yeet the latest revision into place no matter what it is, there are ways to automate that still, such as berberman/nvfetcher, or Mic92/nix-update.

Yes, however one downside is that, afaik, the inputs are downloaded eagerly, not lazily. Alternatively there are things like nix-update and nvfetcher.

You can also use https://github.com/Mic92/nix-update with a nixpkgs git clone.

I run [nix-update](https://github.com/Mic92/nix-update/) to update stuff. If you want to package something new, first identify the programming language/buildsystem the project is using and than look for a similar project in nixpkgs.

I admit that there is an element of, "but I chose an obscure and challenging linux variant, waaah why isn't it supported" here, but (a) there's currently no flatpak and (b) when, for goodness sakes, will major linux projects begin packaging for Nix/NixOS as a matter of course?

It's not hard, and the benefits go far outside merely supporting Nix, as e.g. a flake.nix file would allow this project to generate docker images, and appImage images, as basically afterthoughts. (See e.g. https://github.com/matthewbauer/nix-bundle.)

Nix flake support would also provide a perfectly reproducible build environment, which can help clarify dependencies, and thus help the project build achieve idempotence, but I'll save the full shill for some github issue.

In fact, I'm inclined to roll up my shirtsleeves and help make this real.

https://github.com/matthewbauer/nix-bundle perhaps?

Another way to approach this would be to advocate Nix as the build system for Flatpak or AppImage. Don't know what the status is of nix-bundle, but if it is possible to turn a Nix package into an AppImage with little extra work that would be ideal.

Nix itself is more focused on "distribute from this host with nix, to this other host with nix".

Though, here is e.g. https://github.com/matthewbauer/nix-bundle, which is supported as an experimental command in nix 2.4.

Yes, it's extremely powerful once you truly understand Nix.

There are efforts to improve documentation, but it still is lacking (I think the biggest problem is that Nix is so big, not just the OS but it can be utilized as a build system).

Just with NixOS is not exactly clear how can you for example build your custom image.

I think https://nix.dev/ is approaching the documentation from the right direction.

There are also many pieces that people built that you need to find.

For example some things that I found accidentally:

* https://github.com/matthewbauer/nix-bundle

* https://github.com/cleverca22/not-os

Unfortunately those side projects often have even worse documentation.
