defcmdcljmacro
(defcmd name docstring? [params*] body)Like defn, but the resulting function can be invoked from the command line The docstring? and the arguments metadata are used to generate the cli options.
Example: (defcmd say-hello "Say Hello command" [name & [^{:short "-l" :enum ["en" "es"] :default "en"} lang]] ;; do something with name and lang )
The arguments metadata supports the following attributes: :short The short option prefix, e.g "-o" :long? Allow long name option. Defaults to true. Long name is generated from the argument name. :default The default value. :default-fn A function invoke to get the default value :validate A tuple like [validate-fn validate-msg] to validate the passed option value :enum A vector of allowed values :parse-fn A function to convert the option value string to the desired type

(defopt name docstring? [options*])Declares a global variable that's exposed as a command line option. The docstring? and the options are used to generate the cli options. Example: (defopt verbose "Verbosity Level" :long? false :short "-v" :update-fn inc)
The following options are allowed, and have the semantics as the corresponding options in Clojure tools.cli :short The short option prefix, e.g "-o" :long? Allow long name option. Defaults to true.
