Ultra
A Leiningen plugin for a superior development environment
...The relevant upstream issue to track work on this is greglook/puget#27; from there, Whidbey will need to be updated, and then Ultra will be able to consume the changes. For a detailed list of features, check out the wiki. Note that if you're connecting to a running nREPL server somewhere else, that server needs to have the Whidbey / Ultra middleware passed in as an nREPL server argument in order for you to get syntax-highlighted output on the client side. Stacktraces and exceptions will print in colorized form regardless.
