Ultra is a Leiningen plugin for an absolutely kick-ass development environment. I've written a blog post describing Ultra in greater depth here. Ultra is the rare piece of essentially "finished" software. I've ironed out most of the bugs, and don't plan on adding much in the future. In other words: it's not unmaintained, it's just done. At the moment, Ultra doesn't have ClojureScript support at the REPL. 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.

Features

  • Ultra is a Leiningen plugin for a superior development environment
  • It works best in a traditional terminal with ANSI escape codes
  • Colorized [n]REPL middleware
  • Superior test output
  • Better stacktraces
  • Ultra uses Whidbey as its pretty-printing engine
