Hi thanks for your reply. Sorry my post did suggest I was simply just swapping
.exec for .spawn and hopping it would work ha ha. I've studied the docs and
tried to apply the differences as you can see below.
(def child-process (nd/require "child_process"))
(defn spawn [cmd arg opt] (.spawn child-process cmd arg opt))
(let [opt (utl/cmap->jobj {:cwd project-path})
proc (env/spawn "silk" (array "reload") opt)]
(.on (.-stdout proc) 'data' (fn [data]
(.log js/console data))))
The process runs (I can see it creating the file and directories I expect) but
no logging is preformed. Can you pass a clojurescript anonymous function to a
JavaScipt method?
