so i have an idea for instrumentation with spec. It would be nice if the arguments to a function with a failing fdef were saved somewhere so they could be inspected in the repl, since a lot of times the spec error message is not very useful, and sometimes is so large it nearly crashes emacs.

speaking of that, is there a way to truncate the length of spec error messages?

spec error messages should be really short as of the last changes

what version clojure + spec are you using?

org.clojure/spec.alpha "0.2.176" and clojure 1.10.0

are you sure you're not mistaking the ex-data for the exception message?

(that's the latest release)

yeah, it's the explain data. it's when it's showing the "actual" datatype, which can be huge

that's a tooling thing... CIDER should have a toggle for it

oh ok

(It used to be that the ex-data was also serialized into the message string, which is admittedly awful, but that is no longer the case)

oh yeah i remember those times
