basically just translated pipenv.fish into valid bash.
It automatically activates a pipenv when entering a directory if there is Pipfile in that directory
It also turns on pipenv tab completion
to install just clone this project into your $ZSH_CUSTOM/plugins directory
git clone https://github.com/owenstranathan/pipenv.zsh.git $ZSH_CUSTOM/plugins/pipenv
and then add this plugin to your plugins array in ~/.zshrc
plugins+=(pipenv)
if you don't want zsh to shadow the virtualenv flair on your prompt you'll need to use this plugin
with the virtualenv plugin aswell
