| ttrss | Hi, im using the nixops4 rust bindings crate and im trying to set the "tarball-ttl" option like this,
settings::set("tarball-ttl", "0")
.context("failed to set the tarball-ttl nix option")?;
but unfortunately i get error: failed to initialize evaluator: failed to set the tarball-ttl nix option: Setting not found. Is nix::fetchers::Settings
in libfetchers not being registered? Does anyone know what could be going on?

| lillecarl | * I've vibed these pretty hard, but https://github.com/lillecarl/nanopynix is binding Python to C++ Nix with nanobind. Has both inproc and rpc "mode" for both eval, store, flake and friends, run through ASan and TSan in CI. Supports Python primops, Python stores and yadayada | 09:17:34 |
| lillecarl | Builds and tests against 2.31, 2.34, 2.35 and git/2.36 😄 | 09:22:53 |
| lillecarl | https://asciinema.org/a/5RRpZt6LwneIuwSs I'm using the bindings to build an alternative Nix CLI as well, here's a demo of the REPL. It's using prompt-toolkit for the editing experience, tree-sitter-nix for highlights and triggering autocompletion.
The idea is that I think it's a shame that "doing cool things" with Nix is locked behind the C++ gate, by driving Nix from Python it opens the door for many more developers to build tooling and workflows around Nix and nixpkgs 😄
nix run github:lillecarl/nanopynix/develop#pynix -- repl --flake github:nixos/nixpkgs

 raf | why not help improve the C API? | 19:56:25 |
| raf | I've made a pretty nice nix REPL using my rust bindings for it | 19:56:43 |
| raf | I think it's got a lot of unrealized potential | 19:56:51 |

| lillecarl | raf: I'm more interested in building now than later, C++ has everything now and nanobind exists. I don't care about ABI compatibility | 00:26:46 |
