dotfiles | dotfiles for my Python centric Mac OS X setup

To setup a new Mac from scratch, run $ source setup.up --all which will install Homebrew (if necessary), as well as any useful utilities or Mac applications that may be missing. Note that this setup.sh only handles some basic initial setup, and most new machines will need the following additional installation steps.
Install any desired Python versions with pyenv
Install pip
Install pipx
Install poetry with pipx
Create SSH keys and add them to GitHub. These keys should appear in dotfiles/.ssh where they will be gitignored
Create new GPG keys and add them to GitHub.
Create a new file with [user] signingkey={public GPG key} in a file named dotfiles/.gitconf/local (it will be gitignored)
I use pyenv to manage multiple versions of Python, with the latest Python version set as the default. I use pipx to install global standalone Python command lines tools such as poetry or black. poetry is my preferred dependency management solution, because unlike pip by itself, poetry allows for a clean separation between application dependencies and package dependencies. A sample of how I setup new Python projects can be seen in the pynew function declared in dotfiles/.zsh/02-aliases.zsh.
