Topic: vl-unload-com

[QuestionEverything]

Hello everyone,
Is there a way to UNLOAD the visual lisp extensions?
The reverse of (vl-load-com).

Hi MP,
This looks nice, but wouldn't (_KillProcess) commit a suicide, since it uses the vl- functions by itself? 

Is there some standard command/function for doing this, or the only way would be to collect all the vl- functions and undefine them?

[MP]

Suicide was the suggestion -- and why it was offered "in jest".

[MP]

I suppose one could walk the atoms family and abuse (set to nil) all the vla-* atoms but euuuww.

If I may be so nosey -- why do you need to do this?

It might sound stupid, but I wanted to replicate a situation to see how a code runs without ActiveX.
For example a co-worker is running a few routines on a MacOS and the only fix would be to substitute all the vl-*** functions with vanilla alternatives. 
To guarantee that everything is OK, the most practical way would be to run by yourself the same stuff on the same obstacles - meaning that unload/not load at all the activeX stuff.

Hi,

Most vl-* functions work on MAC because they do not use ActiveX at all.
Only vla-*, vlax-* and vlr-* cannot work on MAC OS systems.
Remember the "new" (since 2012) getpropertyvalue and setpropertyvalue functions can replace in many situations vla-get-* and vla-put-* (and are sometimes more powerfull).

Simply refrain from evaluating (vl-load-com) in the first place...

From this I understand that methods and reactors can not be used.
GetPropertyValue and SetPropertyValue will certainly ease the task, thanks!

I mean thats the problem, my AutoCAD automatically loads acad.lsp, from where like 300 .lsp files, so I can't trace every lsp file that uses (vl-load-com).
Alternative question would be: is there an easy way to prevent this, without messing up my own settings?

Temporarily rename the acad.lsp/acaddoc.lsp files.

Don't try this at home kids.

Code: [Select]

(defun vl-unload-com ( )

    ;;  Untested, quick and dirty, abuse to suit.
    ;;
    ;;  Note: Subsequent vl-load-com call won't restore former functionality.

    (mapcar
        (function (lambda (a) (set a nil)))
        (vl-remove-if-not
            (function (lambda (a) (wcmatch (strcase (vl-symbol-name a)) "VLAX-*,VLA-*,VLR-*")))
            (atoms-family 0)
        )
    )
   
    (princ "\nPoof: Now you're as dumb as a f'ing mac.")

Unfortunately I think that all newer ACAD releases have somewhere (vl-load-com) added inside startup autoload procedures and even until now I haven't figured out where is that initiated... I am though completely sure that this is the case as I have bunch of lisps also autoloaded inside lower releases A2010- and when I type (vlax-get-acad-object) it returns no function definition error message... This is how I check weather my lisps are written like I wanted ((vl-load-com) is specified inside defined lisp command function in all lisps where extensions are needed for correct functionality)...

@MP - you forgot ab VLR-* functions...

M.Puckett, this is awesome! 
I'm left with the impression that you've wrote many awesome stuff, and I like your sense of humour.
