Pretty Stacktrace

[mode89]

Hi there :)

Is there any way to get pretty stacktrace from an exception object?
It would be nice to see something similar to what scittle logs on an unhandled exception.

@mode89 Yes, it's possible but only under some restrictions.

You need to catch the js/Error like this:

(ns dude-ex
  (:require [sci.core :as sci]))

(defn foobar []
  (try (assoc 1 2 3)
       (catch ^:sci/error #?(:clj Exception :cljs js/Error) e
         (->> (sci/stacktrace e)
              (sci/format-stacktrace)
              (run! println)))))

(foobar)

This works in both babashka and nbb/scittle.
