clirun

Run any function from clojure's cli.

Usage

Add an alias to your deps.edn:

  :run
  {:extra-deps {com.phronemophobic/clirun {:mvn/version "1.0.0"}}
   :main-opts ["-m" "com.phronemophobic.clirun"]}

Run any clojure function from the command line. Arguments are parsed as edn.

$ clj -M:run my.ns/foo arg1 arg2 

Examples:

# Write to a file using clojure.core/split
$ clj -M:run clojure.core/spit '"foo.txt"' '[1 2 3]'
$ cat foo.txt
[1 2 3]

# prn the return value by
# adding -p as the first argument
$ clj -M:run -p clojure.core/+ 1 2 3 4
10

# pretty print the return value by
# adding -pp as the first value
$ clj -M:run -pp  clojure.core/macroexpand-1 '(time (+ 1 2 3))'
(clojure.core/let
 [start__6153__auto__
  (. java.lang.System (clojure.core/nanoTime))
  ret__6154__auto__
  (+ 1 2 3)]
 (clojure.core/prn
  (clojure.core/str
   "Elapsed time: "
   (clojure.core//
    (clojure.core/double
     (clojure.core/-
      (. java.lang.System (clojure.core/nanoTime))
      start__6153__auto__))
