paredit

A three-minute Emacs Rocks screencast by Magnar Sveen demonstrating paredit, which edits Lisp code structurally as a tree of s-expressions rather than characters.

Elias Martenson presents his Emacs-based workflow for building a web application (the Potato chat platform) with Common Lisp on the backend and ClojureScript on the frontend. He demonstrates SLIME, Paredit, CIDER and debugger-driven interactive development. The talk is 79 minutes and was given at Emacs SG.
