Yesterday Tim Pope published a new plugin called dotenv.vim (GitHub: tpope/vim-dotenv, License: Vim). It reads variables from a .env or Procfile and sets the corresponding variables in Vim.

This is useful if you have Procfiles for web applications and want to trigger the same commands for local development. Tim notes that you can use dotenv.vim with projectionist.vim and dispatch.vim to get a default :Start of foreman start for projects with a Procfile, which is ideal if you're working on lots of Heroku projects.
