Some time ago I tried to install nix on a macOS Catalina using fish shell and it was not a pleasant experience. In the end, I just gave up because the setup was way too hacky for me.
I’m wondering if this has improved because I would really like to give nix a second try.
What kind of support do you expect?
fish is available to install and if you want to use home-manager, then it also has a couple of options to configure fish.
Sorry about that, I was not clear at my question. My concern is about the installation. For example, following the official installation instructions gives me this error:
➜ ~ sh <(curl -L https://nixos.org/nix/install) --daemon
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0

fish: Invalid redirection target:
sh <(curl -L https://nixos.org/nix/install) --daemon
^
Well, you need to translate this call that is used for POSIX compliant shells to something that fish understands.
That call would also be equivalent to curl -L https://nixos.org/nix/install | sh --daemon if I recall correctly.
Or download and save https://nixos.org/nix/install somewhere on your disk and then run it using sh. cmod +xing it and then run it should even be enough.
Or, if even that is too much work, start a bash or zsh and then run that single command in the child shell.
The command above is to be executed in a bash shell, not a fish one. And Fish is a beautiful idiosyncratic shell; it is neither a POSIX sh or a Bash clone, and will never be. Fish prefers explicit commands and regularity over crazy syntatical constructions.
The <(command) is a “bashism” for process substitution. If you want to use the exact same “one-line download and install” semantics here, you can use the Fish command psub.
I think you can try this:
sh ( curl -L https://nixos.org/nix/install | psub) --daemon
Thanks for the help guys, actually this fish plugin solved the problem.
