feat(users/sterni/nix): add sternis nix lib What you see here is mostly the fallout of me implementing a correct urlencode implementation in nix for Profpatsch's blog implementation (although they'll probably keep it at arm's length). Where I want to go from here: * Extend this library towards general purpose nix™, mainly by implementing missing interfaces which you'd still have to use <nixpkgs/lib> for right now. Reexposing parts of <nixpkgs/lib> with better naming is fine for now, at some point I'd contemplate making this depend on nothing outside of depot, maybe even itself (should be easy we only use yants for an easily replaceable check). * Improve error messages possibly by carefully reintroducing yants. I originally typed essentially everything using yants, but turns out this can a) be dangerous when stuff you are handling throws because type checking means evaluating and b) has a incredible performance cost in some cases. * Reexpose builtins with better naming and slightly wrapped so they don't unrecoverably throw in cases where a null or something would suffice.

feat(users/sterni/nix): add sternis nix lib What you see here is mostly the fallout of me implementing a correct urlencode implementation in nix for Profpatsch's blog implementation (although they'll probably keep it at arm's length). Where I want to go from here: * Extend this library towards general purpose nix™, mainly by implementing missing interfaces which you'd still have to use <nixpkgs/lib> for right now. Reexposing parts of <nixpkgs/lib> with better naming is fine for now, at some point I'd contemplate making this depend on nothing outside of depot, maybe even itself (should be easy we only use yants for an easily replaceable check). * Improve error messages possibly by carefully reintroducing yants. I originally typed essentially everything using yants, but turns out this can a) be dangerous when stuff you are handling throws because type checking means evaluating and b) has a incredible performance cost in some cases. * Reexpose builtins with better naming and slightly wrapped so they don't unrecoverably throw in cases where a null or something would suffice.
