  • Run the main function of a specified namespace:

clj -M -m {{namespace}} {{args}}

  • Prepare a project by resolving dependencies, downloading libraries, and making/caching classpaths:

clj -P

  • Start an nREPL server with the CIDER middleware:

clj -Sdeps '{:deps {nrepl {:mvn/version "0.7.0"} cider/cider-nrepl {:mvn/version "0.25.2"}}}' -m nrepl.cmdline --middleware '["cider.nrepl/cider-middleware"]' --interactive

  • Start a REPL for ClojureScript and open a web browser:
