Ross A. BakerRiffing on a new flake parts project, Le Grille. Similar to Shell Game, but it also tries to keep the treefmt config in sync. Adding a language should add not just a devshell, but a treefmt config using the same tool versions. Also takes care of some other boilerplate, like deadnix+statix+nixfmt and checking headers with REUSE.

raphiz`nix develop`/`nix-shell` are designed to debug derivations.
Yet we all use it to create developer environments - even for projects that don't produce Nix derivations.
Is that an anti-pattern? 🤔

Looking for clarity on Nix developer shells and their design
While digging deeper, I found a few interesting GitHub issues and PRs: "Lighter" and "cleaner" shell for `nix develop` and `nix shell` · Issue #4609 · NixOS/nix · GitHub Allow to get rid of `nix develop` "shell" logic · Issue #7501 · NixOS/nix · GitHub flakes: rename devShell to developPackages by Mic92 · Pull Request #3833 · NixOS/nix · GitHub How to get rid of mkNakedShell entirely · Issue #240 · cachix/devenv · GitHub A recurring theme in these discussions is that there are two very differ...
0hlov3Yesterday I discovered a simple trick to keep my .zshrc loaded when entering a Nix environment:
nix develop . --command zsh -l
# or
nix-shell -p zsh --run "zsh -l"
And because I use it all the time, I added two handy aliases:
alias ndz='nix develop . --command zsh -l'
alias nsz='nix-shell -p zsh --run "zsh -l"'
Now every nix develop feels just like my normal shell =)

It would be really nice to have my personal configs for #Helix, #Neovim, or #Codium in my #homemanager config, but also let a #devshell provide extra config specific to that repo.
Any ideas on how something like this could be achieved?
A big shortcoming of #Nix #devshells is that it's difficult to wrap #editor & #LSP configs for your project.
This is the number one thing I would want a #devshell for after installing dependencies, rendering them always inadequate/incomplete.
Been playing around with numtide's blueprint and devshell to set up a dev environment for a #Gradle application - turns out, it's pretty fun! 🎉
What started as just a simple #DevShell ended up with pre-commit hooks, a basic gradle derivation and a #NixOS module with tests.
This should be a good starting point for my next projects.
#Nix continues to be a rabbit hole I love falling into 🌀
