Vim is a powerful text editor. Clojure is a powerful programming language. While its been possible to edit Clojure code in vim for years, the toolchain has improved greatly over the past year. Today we're going to see how we can integrate vim with our Clojure REPL environment.

Life without integration

In a shell session, let's fire up a Clojure REPL. I'm going to use lein repl to do this. In another shell session, let's start vim and edit a clojure file.

    "template": "(ns {dot|hyphenate})\n\n"
  },
