Getting the feel for the Light Table's instarepl (screencast)

Today I was sitting at a coffee shop and none of the wireless networks worked so I started to explore my local stuff and I did find recent version of the Light Table sitting in my Downloads folder. I didn't have much time to play with any of the previous versions so I thought this could be the good time to give it a try. I was especially interested in how instarepl could help me solve problems in Clojure so I tried it on my favorite code kata called String Calculator. I recorded screencast of this experiment which you can see below.

My first impressions are pretty positive as it helped me multiple times to get the code to work pretty fast. There were also times where I could use a little more help (e.g. it didn't show much useful information in the add function at the beginning). But overall it was pleasant experience and I'm looking forward for future versions. Maybe someday I'll switch from the Emacs/Evil to the Light Table. Or the best stuff will get ported to the Emacs... :)

Q: Does the Light Table contain some Clojure documentation functionality? E.g. something like eldoc-mode / clojure-cheatsheet in Emacs?


  1. To answer your Q - not yet :) But according to the original LightTable blogpost it will http://www.chris-granger.com/2012/04/12/light-table---a-new-ide-concept/ And I'm very much looking forward to that. However LT is still far from being as powerful Lisp editor as Vim & SLIMV or Emacs are.

  2. Excellent video, thanks so much for sharing.

  3. I just had a look at LightTable - coming from Emacs and judging from a brief look, a bunch of things are still missing to get me into that emacs-clojure-feeling.
    I really enjoyed your video, though!
