[racket] How to make racket to show the call stack when get an exception?

Bonjour,

For having the stack trace you need to use the errortrace library http://docs.racket-lang.org/errortrace/.

If you run drracket you can activate it or not when you choose the language.

If you run geiser you can put "(require errortrace)" in ~/.racket-geiser.

If you run from the command line so "racket -l errortrace my-script.rkt" will show you the stacktrace.
