Hey Dave,
Thanks for that heads up. I originally wanted auto-compiling for HAML and SCSS. But then thought why, when I could just use edn with Hiccup and Garden. Now, a lein-hiccup, or some auto compile tool doesn't exist to my knowledge. So i) I had to do that work anyways. Then I spent 20 mins replicating the functionality for Garden. Also I think lein-garden tracks edn style definitions, inlined in your existing Clojure code, whereas ii) I wanted a separate directory watcher on edn files (no namespaces needed).
But there's nothing that says that functionality in garden-watch couldn't be collapsed into lein-garden. It's pretty straightforward code.
