Grenchman lets you run Clojure code quickly. By connecting to a running nREPL server you avoid JVM startup time, streamlining your development workflow. It includes its own repl client implementation featuring full GNU Readline support as well as the ability to invoke Leiningen tasks.

Just launch an nREPL server in the background with lein trampoline repl :headless or by embedding nREPL in your codebase, and grench will connect to it and run your code there.

Please report issues on GitLab or on IRC.
