can planck do an exec? one where it passes the input/out/err to subprocess… like bash does in an exec ?

Planck has a planck.shell namespace that mimics clojure.java.shell

(So, you can't feed the subprocess a stdin for example.)

sure, the usecase I have in mind is that planck do somethings, but then invoke another program to continue.... like setting up a file with some contents and then launching vi to edit the file

I suppose I can wrap a bash script to do this.

Correction to the above: Planck's sh imitation lacks the ability to pass a stream in for the :in parameter.

quick question, since I have your brain.

cljs.user=> (instance? String "ff") ⬆️ WARNING: Use of undeclared Var cljs.user/String at line 1 Right hand side of instanceof is not an object

what is the namespace for String?

An alternative answer: Use (string? "ff")

You can check to see how ClojureScript implements string?

yea, thats what I did.

(def ^{:arglists '([x]) :doc "Return true if x is a String" :added "1.0" :static true} string? (fn ^:static string? [x] (instance? String x)))

and that seems to show (instance? String x)

https://github.com/clojure/clojure/blob/clojure-1.9.0-alpha14/src/clj/clojure/core.clj#L160

That's Clojure

cljs.user=> (source string?)
(defn ^boolean string?
  "Returns true if x is a JavaScript string."
  [x]
  (goog/isString x))

well… started from http://cljs.info/cheatsheet/

so I didnt expect to land in clojure

Thanks,!!
