Basic Command Line REPL UI

The clojure command will start a REPL by default or if given the --repl argument.

clj is a script that wraps the clojure command and uses rlwrap, an external readline command, to navigate REPL history via the ↑ and ↓ keys.

Use clj when you want to run a repl (or preferably use rebel readline instead) and clojure for everything else.

Hint::rebel readline feature rich repl

rebel readline is a command line REPL UI that provides interactive help, function autocomplete, signature prompts and many other features to provide a very rich REPL experience.

practicalli/clojure-deps-edn includes the -A:rebel alias to run rebel readline REPL.

clojure command in a terminal window starts a Clojure REPL and shows the version of Clojure used. The command does not need to be in a directory containing a Clojure project.

Clojure code can now be run in the REPL by typing the code and pressing the ENTER key.

Exit the REPL by typing Ctrl+D (pressing the Ctrl and D keys at the same time).
