Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Unable to setup GUIX_PROFILE with Fish
I am not using Guix's Fish because right I just installed it and was hoping to kinda get my packages up to snuff for what I keep on my desktop. Though I was about to install foreign-env via omf and that seems to work! I am super new to Guix so I still gotta read up on Guix Home. I literally have only installed like 6 packages right now haha.

Our Roadmap for Nix
The official installer leverages an initialization script, to be sourced at shell init time, which is written in POSIX shell. Fish can't just source it because it's not compatible with POSIX shell.
> I then searched the Internet and found a very "creative" workaround for Arch users that didn't work either.
Arch users shouldn't need anything special here.
You can use fenv¹ to source it, you can translate it to bash using babelfish, or you can exec into fish after running bash to log in (make sure to set $SHELL after if you choose that option). Just make sure you do it as early as possible if you want to use things installed by Nix in your other Fish config snippets.
I think Home Manager will also take care of this for you. (The other module systems, Nix-Darwin and NixOS, both do.)
If you wanna do it like NixOS does, you can install Fish via Nix and then create your own preinit environment script in /etc/fish. This has the advantage of setting up your Nix environment variables before any other config is sourced. You can take a look at it here, which also explains some of the Fish initialization process: https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/p...
and here's where the hooks go in the Fish package, where the comments describe the Fish initialization process in detail as well as why things are done this way on NixOS: https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/p...

Why not fish
That's just not true, most stuff already has a fish equivalent, and for the minority which doesn't there are plugins like foreign-env
- Nsh: A fish/bash-like Posix shell in Rust

Trouble with fish shell setting environment variables at login
I'm also interested in the correct way of doing this. Right now, I cheat by using the fenv plugin to source a bash ~/.profile file:

NixOS and My Descent into Insanity
Have you tried https://github.com/nickel-lang/nickel-nix ?
I didn't use it yet, but looks like this supposed to do it.

The guide to software development with Guix
These days those aren't the only options; you can also use Nickel: https://github.com/nickel-lang/nickel-nix
Which isn't fully baked, no, but here's hoping.

Announcing Nickel 1.0, a configuration language written in (and usable from) Rust
One target-use case of Nickel is to be used as an alternative front-end for Nix (instead of Nix expressions). There is a draft RFC and a repository to use Nickel to write development shell (Nixel). The goal is that, one day, you can actually just transparently call to Nix code and into Nixpkgs. Until then, I totally understand that nothing can be the power of levering Nixpkgs... so your approach makes sense :)

Our Roadmap for Nix
Undecided; see https://github.com/nickel-lang/nickel-nix for a proof-of-concept of an integration that requires making no changes to either Nickel or Nix.
What are some alternatives?
babelfish - Translate bash scripts to fish
nix-book - Nix documentation – centralized community online learning resource for Nix
nushell - A new type of shell
go-nix - Elements of Nix re-implemented as Go libraries [maintainer=@flokli]
fish-shell - The user-friendly command line shell.
flake-utils - Pure Nix flake utility functions [maintainer=@zimbatm]
vscode-yaml - YAML support for VS Code with built-in kubernetes syntax support
oursh - Your comrade through the perilous world of UNIX.
nixpkgs - Nix Packages collection & NixOS
nix-doc - An interactive Nix documentation tool providing a CLI for function search, a Nix plugin for docs in the REPL, and a ctags implementation for Nix script
guix-installer - A GNU Guix installer image with the full Linux kernel!
