Re: Create dynamic vars programmatically

(doseq [s '(a b c)] (intern *ns* s 0)) creates non-dynamic var's.

However, how could I produce dynamic var's. I tried with-meta but failed. In other words, what does (def ^:dynamic a) internally do?

You can use clojure.lang.Var.setDynamic https://github.com/clojure/clojure/blob/master/src/jvm/clojure/lang/Var.java#L116

kind regards

Beware however, that interning vars programmatically is not recommended. If you need fresh vars during runtime, use with-local-vars, which also produces dynamic vars.

Sorry for delay, I had difficulties with Google Groups ... posted several times.

Thanks about the hint about with-local-vars, Marc
