If you call (interactive-p)
from inside a (catch... or (condition-case...
that is nested within a higher-level (catch... or (condition-case...,
then when you run the code interactively,
if the code has NOT been byte-compiled,
it works correctly (interactive-p returns t);
but if the code HAS been byte-compiled,
it fails (interactive-p returns nil).
The code below illustrates the problem if you run it both
byte-compiled and not byte-compiled, and compare the results.
(defun cctest ()
(interactive)
(catch 'cctest
(message "before condition-case in catch, (interactive-p) = %s"
(interactive-p))
(condition-case nil
(message "---inside condition-case in catch, (interactive-p) = %s"
(interactive-p))
(error nil))
(message "after condition-case in catch, (interactive-p) = %s"
(interactive-p))
(catch 'cctest
(message "---inside catch in catch, (interactive-p) = %s"
(interactive-p)))
(message "after catch in catch, (interactive-p) = %s"
(interactive-p)))
(message "")
(condition-case nil
(progn
(message "before catch in condition-case, (interactive-p) = %s"
(interactive-p))
(catch 'cctest
(message "---inside catch in condition-case, (interactive-p) = %s"
(interactive-p)))
(message "after catch in condition-case, (interactive-p) = %s"
(interactive-p))
(condition-case nil
(message "---inside condition-case in condition-case,
(interactive-p) = %s"
(interactive-p))
(error nil))
(message "after condition-case in condition-case, (interactive-p) = %s"
(interactive-p)))
(error nil)))
