What is do-verbose?

[Rangarajan]

I saw use of do-verbose function in SB's "Etude1OrchestraForumExerpt.opmo" file. To the extent I remember, it is not in common lisp and it is not documented in Opusmodus. I would like to learn about it.

Also, is it perhaps possible to globally switch off the constant tracing printout likely caused by this macro. I would prefer to only see results in the listener, and to see such tracing output only when needed for debugging.

 

Thanks!

 

Best,

I don't understand what you mean by "constant tracing printout likely caused by this macro".

Thanks for coming back. Pretty much all Opusmodus functions calls are traced (https://en.wikipedia.org/wiki/Tracing_(software)) in the listener, when they are called. (Apologies if the link is over the top, just want to clarify.)

 

Example, which causes a trace of rnd-pick.

 

(loop repeat 10
  collect (rnd-pick '(1 2 3)))

 

I understand that this can be very useful for debugging, in particular if further information is shown like the function arguments etc., but I would like to disable it by default. Is that possible perhaps?

 

BTW: Below is the definition of a very similar tracing function, that allows to control which functions are currently traced, or to switch of tracing globally.

 

Best,

Torsten

 

(defvar *dbg-ids* NIL "Identifiers used by dbg")

;; was once named debug, but symbol debug is already defined in common-lisp (see opimize)
(defun dbg (id format-string &rest args)
  "Print debugging info if (DEBUG ID) has been specified"
  (when (member id *dbg-ids*)
    (fresh-line *debug-io*)
    (apply #'format *debug-io* format-string args)))

(defun start-debug (&rest ids) 
  "Start debug output on the given ids."
  (setf *dbg-ids* (union ids *dbg-ids*)))

(defun stop-debug (&rest ids) ; was once named undebug
  "Stop debug on ids. With no ids stop debugging altogether."
  (setf *dbg-ids* (if (null ids) NIL
                      (set-difference *dbg-ids* ids))))
