Directory specific environment variables with direnv
direnv is a very simple but useful tool. Create a .envrc file that defines some environment variables, e.g.:
export MY_VAR=123
export SOMETHING_ELSE=blahWhen you cd into that directory, the environment variables are loaded. When you cd out, they are unloaded.
