Fish is supported?

[hedefalk]

Originally reported here because I thought it was zed's fault (because I seldom just start a fish from my fish): zed-industries/zed#21269 (comment)

I'm on Macos with nix-darwin and fish is my default shell. To reproduce:

mkdir new-devenv-scaffold
cd new-devenv-scaffold/
devenv init

then just

>fish

🐟fish

So some bashism here that I don't fully understand…

A simple direnv with a flake is working fine, but as soon as I introduced devenv into my mix this happens.

Note, I've added:

impure: true

to the deveny.yaml, forgot to write that. In my original use I had "use flake --impure" in the .envrc instead.
