How to Install asdf with Nix Home-manager

1. First, add asdf to the Nix configuration with the package named asdf-vm. Add the following line to your configuration.nix file:

   environment.systemPackages = with pkgs; [
     asdf-vm
   ];

2. Next, add the following lines to your .bashrc file:

   . "$HOME/.nix-profile/share/asdf-vm/asdf.sh"
   . "$HOME/.nix-profile/share/bash-completion/completions/asdf.bash"

   These lines will load asdf into your shell.

3. Reload your .bashrc or open a new terminal to apply the changes.

4. Verify that asdf is properly installed by running the following command:

   asdf --version

   This should output the version number of asdf.

That's it! Now you can use asdf with Nix.

Using home-manager with bash I used something like this to ensure it always looked in the right place:

programs.bash = {
  enable = true;
  # ... other things here
  initExtra = ''
    . "${pkgs.asdf-vm}/share/asdf-vm/asdf.sh"
    . "${pkgs.asdf-vm}/share/asdf-vm/completions/asdf.bash"
  '';
};
