I have many exception handlers, mostly handle-exceptions but some
condition-case, and I'd like to run some tests and turn OFF the
exception handling. I tried using a proc but that does not work:
(define (mt-faux-handle-exceptions exn alt . cmds)
(let ((alt-proc (lambda ()
(let ((exn exn))
alt))))
(apply lambda '() cmds)))
The exn variable is not seen by the alt code and a "Error: unbound
variable: exn" message is issued.
I've tried a macro but I don't know enough to make it work. This
starting point works:
(define-syntax common:handle-exceptions
(syntax-rules ()
((_ exn-in errstmt ...)
(handle-exceptions exn-in errstmt ...))))
But I run into trouble as soon as I try to replace the actual
handle-exceptions with something else.
Is there any built-in switchable on/off exception handler or does
someone have a macro they can share that does what I need or something
similar?
Any help appreciated.
Thanks,
Matt
