CLOJURE(1) General Commands Manual CLOJURE(1)

clj, clojure - runners to launch Clojure programs

clj [clj-opts] [-Aaliases]
clojure [clj-opts] -X[aliases] my/fn? [kpath v ...] kv-map?
clojure [clj-opts] -T[name|aliases] my/fn [kpath v ...] kv-map?
clojure [clj-opts] -M[aliases] [init-opts] [main-opts] [args]

The clojure tool is a runner for Clojure programs. clj is a wrapper for clojure that uses rlwrap to provide a better interactive experience. Users will typically run clj.

You can launch a Clojure REPL by running clj.

See the Deps and CLI Guide below for more complex usage.

The clj and clojure scripts can take three types of options, as shown in the synopsis. clj-opts are used to build the java-opts and classpath. init-opts refer to Clojure code to execute. main-opts are options to clojure.main.

Pass opt through in java_opts, ex: -J-Xmx512m
Concatenated aliases for REPL execution, ex: -A:dev:mem
Exec alias to invoke one or more functions that take a map, with keypath/value overrides. Function must either be supplied or be in :exec-fn argmap for alias
Exec clojure.main, either from opts in alias or command line
Prepare - download libs, cache classpath without executing
Deps data to use as the last deps file to be merged
Compute classpath and echo to stdout only
Print dependency tree
Do NOT compute or cache classpath, use this one instead
Ignore the ~/.clojure/deps.edn config file
Force recomputation of the classpath (don't use the cache)
Print important path info to console
Print environment and command parsing info as data
Set specific number of download threads
Write a trace.edn file that traces deps expansion
--
Stop parsing dep options and pass remaining arguments to clojure.main
Write version to stdout and exit
Write version to stderr and exit

Load a file or resource located at path
Eval exprs in string; print non-nil values
Report uncaught exception to target: "file" (default), "stderr", or "none", overrides System property clojure.main.report

Call the -main function from namespace w/args
Run a repl
Run a script from a file or resource located at path
-
Run a script from standard input
Print this help message and exit

This script reads configuration from deps.edn files. It will check against deps.edn files in the system root location, the user configuration directory (usually ~/.clojure), and the local directory. Files in each of these locations, if they exist, are merged to form one combined configuration file. The last specified configuration file's options overwrites any earlier files (e.g. local configs take priority).
