When I try to do instrument my-test-err4 below for edebug with
C-u C-M-x
I get an error saying
edebug-syntax-error: Invalid read syntax: "Expected", (&rest
&or (symbolp &optional form) symbolp)
Can someone please explain to me what I have done wrong here?
(defvar mumamo-use-condition-case nil)
(make-variable-buffer-local 'mumamo-use-condition-case)
(put 'mumamo-use-condition-case 'permanent-local t)
(defvar mumamo-debugger 'mumamo-debug-to-backtrace)
(make-variable-buffer-local 'mumamo-debugger)
(put 'mumamo-debugger 'permanent-local t)
(defmacro mumamo-condition-case (var body-form &rest handlers)
"Like `condition-case', but optional.
If `mumamo-use-condition-case' is nil then just evaluate
BODY. Otherwise do the same thing as
(condition-case VAR
BODY
HANDLERS)."
(declare (indent 2) (debug let))
`(if (not mumamo-use-condition-case)
(let* ((debugger mumamo-debugger)
(debug-on-error (if debugger t debug-on-error)))
,body-form)
(condition-case ,var
,body-form
,@handlers)))
(defun my-test-err4 ()
(interactive)
(mumamo-condition-case err
(my-errx)
(arith-error (message "here"))
(error (message "%s, %s" err (error-message-string err)))
))

It's because you've told edebug that mumamo-condition-case has the same
syntax as `let', but then you go on and use it very differently.
You need to fix your `debug' declaration.

Thanks, I see - at least what to do. But the (debug ...) form is still
mysterious.
