den + numtide/devshell + flake-parts + with-inputs + flake-file (+ direnv?)

I have a question about the best way to connect all of these libraries together so that the DX is similar to flakes. Namely, here's my goals:

1. I want to be able to type a short, 1-2 word command to enter a devshell (like nix develop).
2. It'd be nice if it could integrate with direnv/lorri via a .envrc file.
3. I'd like to use the forwarder you've displayed in the flake-parts-modules template to define the devshell.

I've been successful with nix develop -f . devShells.aarch64-darwin.default as a way to kick-start my devshell. But I'd obviously like to be able to start it with a shorter command and without having to handwrite the system each time.

Any thoughts on how to make all these wonderful things work together?

Your .envrc should just work, my infra uses that with use nix which loads my shell.nix, and the default shell could be one provided by numtide/devshell, just see how flake-parts-modules exposes a numtide shell. Regarding flake-file, I always use the nix-shell command from flake-file, but a shortcut at Justfile can be enough.

I find that using Justfile (with args) for common stuff is enough for me.

maybe related #7, try that "nix flake"-command compatibility layer. How is speed using that ?

Try using nix flake and trix flake commands to see if you notice any significant difference, and also normal nix-shell or nix-build stable commands.

Found this: https://github.com/dtomvan/flake-parts-noflake see their results.txt maybe worth adding trix and/or Den
