C2 Visual REPL

Render your Clojure visualizations as you write 'em.

To start:

lein run  --port 8987 --path resources/samples/

Serves up the final form of the most recently changed file in resources/samples/ and automatically refreshes your browser.

If you don't have Leiningen installed, you can download the pre-built JAR file:

java -jar c2-starter.jar --extract

which will extract pre-built sample visualizations to the default samples/ directory and start watching. Change any files in there (or add a new ones) to update the web server visualization.


  • Auto-compile+refresh ClojureScript
  • Pretty stacktraces in browser
  • ProGuard or otherwise shrink UberJAR.
