;; ns cheatsheet https://gist.github.com/ghoseb/287710/

;; Work with library in REPL - example Cheshire
(boot.core/set-env! :dependencies #(conj % '[cheshire "5.5.0"]))
(require '[cheshire.core])

;; add dependency
(set-env! :dependencies #(conj % '[foo/bar "1.2.3"]))

;;start repl in project namespace
(task-options!
  repl {:init-ns 'cli.core 
        :eval '(print "Welcome \n")}

;; Make changes to files available to repl without restart
(require '[clojure.tools.namespace.repl :refer [refresh]])
(apply clojure.tools.namespace.repl/set-refresh-dirs (boot.core/get-env :directories))
boot.core => (clojure.tools.namespace.repl/refresh)
; for some reason, required to provide namespace despite previous require
  
;; Changes to files available to repl automatically
(deftask dev
  ""
  []
  (comp
    (repl :port repl-port )
    (watch)
    (speak)
    (refresh)))
 ; then start a seperate REPL client
  boot repl -c --port 5600
  
;; Add dependency without a REPL restart 
boot.core => (set-env! :dependencies '[[group-id/artifact-id version-string]])
boot.core => (require '[dep :refer :all])

;; TODO Execute tests from within REPL
;; TODO Execute all tests when files change
;; TODO Only execute tests related to the changed files 
  
(merge-env! :dependencies '[[foo/bar "1.0"] [baz "2.0"]])
