Direnv is pretty neat and I use it all the time. But in repos that are not exclusively mine, you cannot add .envrc files and I kept losing them. direnv-new, above, will create a file under ~/.config/direnv and symlink it, and direnv-install-links will install all these links in case you cleaned a repo or something. I combine it with dotfiles in git so I can version control my .envrc files and share them between machines.
