My father is a greate chef :)
Dad is a small configuration management tool for Clojure. This project is heavily inspired by mitamae.
-
Easy to start — Download single binary and run it.
-
Minimum to remember — May not write code for Dad often
Download binary from releases.

./dad your_task.cljHere is a example to install Clojure command line tools.
#!/usr/bin/env dad --no-color --dry-run
(package ["curl" "rlwrap"])
;; You can define function as you like
(defn curl [m]
(let [{:keys [path url]} m]
;; `file-exists?` is a built-in function in dad.
(when (and (not (file-exists? path))
(string? url))
(execute (str "curl -sfLo " path " " url)))))
(curl {:path "/tmp/install.sh"
:url "https://download.clojure.org/install/linux-install-1.10.1.489.sh"})
(file {:path "/tmp/install.sh" :mode "755"})
(execute {:cwd "/tmp" :command "./install.sh"})
(file {:path "/tmp/install.sh" :action :delete})-
