alt Hacker NewsIt's a pretty special language, lazy evaluation and very basic types. However after spending the time to learn it to an intermediate level I think it's pretty great.
Flakes are not great however, they're what happens when you "overdo it", sadly the momentum is behind flakes because some UX/DX improvements came along with them (lockfile in repo).
I think the stdenv being built on bash is worse than Nix language.
Module system errors can be very hard to troubleshoot because of lazy eval, sadly I can't see a reasonable solution without worse tradeoffs :(
The flakes were the main UX/DX improvement for me. Before them I honestly could not do anything. The learning curve was so incredibly steep it almost felt like the people behind Nix were being malicious or intentionally gatekeeping. You finally stumble onto something you can at least partly understand, but then the powers that be throw two last obstacles at you like,
First, flakes are "experimental", so you have to enable them. Back then there were like three slightly different CLI commands to do it, and it felt like none worked from like 5 tutorial tabs I had open, putting it `experimental-features =` into flake you are trying to switch to does not work obviously.
Then you hit the classic situation where your flake is not committed or staged, so Nix refuses to see it. And instead of telling you that, it prints this abomination of error message "error: path '/nix/store/0ccnxa25whszw7mgbgyzdm4nqc0zwnm8-source/flake.nix' does not exist" (https://determinate.systems/blog/changelog-determinate-nix-3...)
I would not wish learning Nix from zero on my worst enemy, and I say that as someone who uses nix-darwin, devShells, deploy-rs and so on every day. The UX/DX is really bad, but nothing else comes close to its capabilities.
Sorry for rant but without flakes I would not make it.
