Pretty printing exception stack trace¶

Function pretty_print_stacktrace accepts a stacktrace (third element of a caught exception tuple, see exceptions syntax). It produces a string, with lines, each representing one stack frame, first being the most recent one.

Example:

try
    expression
catch
    (:badarg, error_msg, stacktrace)  -> Exception::pretty_print_stacktrace stacktrace |> IO::println_err
end
