Direnv .envrc defaults for python

.envrc

### My current .envrc defaults for defaults for a python project

# I use asdf to manage runtimes.
# Using asdf with direnv like this removes the 
# annoying shims, which for me is more reliable
# less confusing and slightly faster
use asdf

unset PYTHONHOME

# auto activate virtual environemnt
export VIRTUAL_ENV=$PWD/.venv
PATH_add $VIRTUAL_ENV/bin
source activate

# modify to suit current project
export PROJECT_ROOT_PATH="${PWD}"
export PYTHONPATH=$PROJECT_ROOT_PATH

# Optionally if you have a .env file and 
# if you don't want to use dotenv from python
dotenv .env
