shell.nix

# Note: This shell.nix is deprecated. The complete setup
# of my development environment in the unstable.nix file
# inside of the gkapfham/nixos repository handles everything.

# Note: Enter this shell before running the following commands

# Command to enter the shell environment: nix-shell shell.nix
# Command to run Quarto to make web site: quarto render
# Command to run Quarto to perform a preview: quarto preview

# Note: This shell environment does not contain the minify-html
# Python package because it is not included in the nixpkgs
# repository. However, this is available through the Poetry shell
# when you type the command: poetry shell in the directory that
# contains the pyproject.toml file. Importantly, note that the
# quarto commands do not "pick up" the poetry shell's environment.
