    As sibling comments mention, this would struggle with edge-cases, and require too much buy-in from packagers.

    A less ambitious approach would be creating/extending a static analyser/linter for Nix (there are already a few out there). This could nudge packagers towards certain styles, which language implementations could optimise for.

    For example, an interpreter could have multiple implementations of the attrset interface (key/value mappings) with different performance characteristics, using some default for literals like '{ foo = "bar"; }' and a specialised version for known use-cases like nixpkgs.lib.nameValuePair ( ) (mentioned in a sibling)

    Linters could then spot when such functions are appropriate, e.g.

    Cross-posting from - Read my small guide about nix language - Use sourcegraph for searching. Github isn't too good for that. Example - Read/ask questions here or at - search for issues here - At the beginning try to use as little as possible additional abstraction layers like home-manager, devos etc. - You may look at my config there are other documentation sources listed at Be aware that those sources maybe outdated.

    which would likely be copy-pasted from the project README. The yml file specifies version numbers for dependencies. The SAT solver is deterministic. For other languages like C maybe the project didn't specify dependency version. So you need to figure them out when you first get a successful build, then specify their versions in apt. You can specify version numbers in the apt-get install line.

    Yes, this is reproducible. Definitely good enough for most business use cases. When I say reproducible I do not mean ivory tower math proof reproducible. I just mean that the code will run on the relevant machines they are targeting. As I wrote in my initial comment. And as I defined at the top of this comment.

    Also Nix provides a worse experience for pinning dependency versions since it does not have a native concept of version numbers [0]. Instead people have to grep through the Nixpkgs repo to find the correct hash of their dependency version.

    > This is even more true for Nix, which has the largest and most up-to-date package repositories out there

    No, Docker has the closure (to borrow Nix's terminology) of all of the package managers in that graph. If you add the height of the Debian packages with Pypi and Hackage you already have Nix beat. You can keep adding - cargo, ruby gems, etc all in their native package managers. If Nix were better off then people would be adapting Nix packages to other ecosystems. But the reality is the other way around.

    > Plus, with Nix, you can easily make a new package based on existing packages with a mere few lines of code if the existing packages doesn't fit your needs. Other package managers besides Guix doesn't offer you that flexibility so you'd have to compile from scratch

    With Nix, you are forced to make new packages based on existing packages. That is not a benefit. Regarding "if the existing packages doesn't fit your needs", compiling from source is not a big deal since Docker caches output artifacts.
