I've kept my dotfiles in a git repo for a while, but I've only recently automated the installation of the rest of my dev environment with make: https://github.com/sethwoodworth/devenv-setup I have my ~/.config dir in another repo, and my (neo)vim config in a third. I use pyenv to install and select python versions, pipsi for isolated executable python packages like mycli, and I've been trying to migrate my projects to poetry after having a bad time with pipenv last year.

FYI, pipsi is unmaintained and recommends using pipx instead.
