docopt.clj

Clojure implementation of the docopt description language.

Forked from @signalpillar's fork of docopt, originally by @postamar.

Usage

babashka

In order to add docopt.clj to the classpath, you can either

• Use an environment variable

  cd babashka
  export BABASHKA_CLASSPATH=$(clojure -Spath -Sdeps '{:deps {dev.nubank/docopt {:mvn/version "0.6.1-fix6"}}}')
  ./naval_fate_env.clj
  

• Dynamically include it with (require '[babashka.classpath :refer [add-classpath])

  cd babashka
  ./naval_fate_dynamic.clj
  

babashka/common.clj contains an example of how to call docopt's entrypoint function.

In both cases, the output should be

$ ./naval_fate_env.clj ship Unicorn move $'20°37\'42.0"N' $'70°52\'25.0"W' 
{"--drifting" false,
 "--help" false,
 "--moored" false,
 "--speed" "10",
 "--version" false,
 "<lat>" "20°37'42.0\"N",
 "<long>" "70°52'25.0\"W",
 "<name>" "Unicorn",
 "mine" false,
 "move" true,
 "new" false,
 "remove" false,
 "set" false,
 "ship" true}

tools.deps

Save the following script as test-script and make it executable with chmod +x:

#!/bin/sh
#_(
  DEPS='
   {:deps {dev.nubank/docopt {:mvn/version "0.6.1-fix6"}}}
   '

  OPTS='
  -J-Xms256m -J-Xmx256m
  -J-client
  -J-Dclojure.spec.skip-macros=true
  '

  exec clojure $OPTS -Sdeps "$DEPS" -i "$0" -m docopt.example "$@"
)

(ns docopt.example
  (:require [docopt.core :as docopt]))

Tests

Run lein test to validate all tests. The tests are automatically downloaded from the language-agnostic testcases.docopt file in the reference implementation, master branch commit 511d1c57b5. Please feel free to (re)open an issue in case this implementation falls behind.
