Ladies and gentlemen of a Lisp persuasion, Clojurians and Clojuristas, followers of the paren and everyone else covetously eyeing the greener grass,<p>I made an open-source thing that I would like to share with you. My elevator pitch is that it'll make you forget all about regular print debugging in 10 minutes straight. The slightly longer pitch is this:<p>#>(tag'n'trace any Clojure(-Script) form to `tap>` and Portal with automatic last-input function replay on eval, instant re-render and hassle-free insertion of traced data into the REPL)<p>And before I end up pasting half the README here in bits and pieces, just go and check out the damn thing, will ya. There's a screencast and everything.<p><a href="https://github.com/gnl/playback">https://github.com/gnl/playback</a>
