Hi John,
You’ll have to arrange in some way to create a namespace so that defs work.
While the cljs.user namespace is the default namespace when :ns is not
specified, it is not automatically created for you.
Here is a way to do it directly in the script:
function evalstr() {
clgs.core.evalCljs("(ns cljs.user)");
var s = "(def x 3)";
var res = clgs.core.evalCljs(s);
Logger.log("output: " + res);
var s = "(+ x 2)";
var res = clgs.core.evalCljs(s);
Logger.log("output: " + res);
return res;
// In the menu above, click "Run" -> "evalstr"
// Then click "View" -> "Log"
}
[16-09-07 18:39:26:408 PDT] cljs in: (ns cljs.user)
[16-09-07 18:39:26:539 PDT] cljs out: {:value nil}
[16-09-07 18:39:26:540 PDT] cljs in: (def x 3)
[16-09-07 18:39:26:672 PDT] cljs out: {:value 3}
[16-09-07 18:39:26:673 PDT] output: 3
[16-09-07 18:39:26:674 PDT] cljs in: (+ x 2)
[16-09-07 18:39:26:767 PDT] cljs out: {:value 5}
[16-09-07 18:39:26:769 PDT] output: 5
If you are curious, Planck sets up cljs.user here

And Replumb accomplishes the same in a different way here:
