Set project based Unix environment variables

Emacs side of things

package-install RET envrc

In your project

This is what I used for Python based projects. I use pipenv and Pipfiles. Thus, I need to set VIRTUAL_ENV to make everything work.

$ cd ~/src/awesome-app
$ direnv allow

Find where the virtual environemnt actualy resides:

$ pipenv run which python3 | sed 's#/bin/python3$##'

Add this to an .envrc in your project root:

$ vim .envrc
export VIRTUAL_ENV=/home/torstein/.local/share/virtualenvs/awesome-app-EpEGAS3U
export PATH=${VIRTUAL_ENV}/bin:$PATH
