clj

Clojure tool to start a REPL or invoke a specific function with data. All options can be defined in a deps.edn file. More information: https://clojure.org/guides/deps_and_cli.

• Start a REPL (interactive shell):

clj

• Execute a function:

clj -X {{namespace/function_name}}

• 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:

clj -Sdeps '{:deps {org.clojure/clojurescript {:mvn/version "1.10.758"}}}' --main cljs.main --repl
