## What it is
Ultra is a Leiningen plugin that enhances the Clojure development environment with a colorized REPL, syntax-highlighted source, clearer test output, and improved stacktraces. It is built on top of Whidbey for pretty-printing and is configured via Leiningen profiles.

## Use cases
- colorize my clojure repl output
- get better stacktraces in clojure tests
- pretty-print clojure data structures in the repl
- improve leiningen test output readability
- syntax highlight source code in the clojure repl

## When to choose
- you use Leiningen with Clojure on the JVM and want a nicer REPL and test output out of the box
- you want colorized stacktraces and pretty-printed data without manual setup

## When to avoid
- you need ClojureScript REPL support
- you use very recent JDK or Clojure versions, as the project is effectively finished and may no longer work with modern toolchains

## Facets
- artifact type: plugin
- maturity: maintenance
- function: developer-tools, testing, logging
- domain: developer-tools
- platform: jvm, cli
- tags: clojure, leiningen, repl, pretty-printing, stacktraces, test-output, command-line
