This script is meant to be used for your bash prompt. It simply detects if the current directory likely includes a virtual environment that can be activated.

1. $ git clone https://github.com/tstringer/venvdetect.git
2. Create a symlink from a path in $PATH to the python script
3. Change your $PS1 env var in your .bashrc to include a call to the python script

A few things to note...

1. This script will use an optional env var VENV_DIRS for a comma-separated list of your common virtual environment directories. This will default to venv if unset
2. It won't show an "available" virtual environment if that virtual environment is already activated
