#third party management
2 messages in this thread
Tony,
Some time ago, I think you had a few things to say about third party LISP
management. I am trying to set up the server version of ACAD for our
company, and it would really be nice if you could dig that stuff out. If
you need more of a memory tickle, the problem has to do with multiple third
party apps all wanting to futz with ACAD.LSP. As I recall, you suggested
an ACAD.LSP which kept its own list of apps to load at run-time.
Ideally, I'd like to have one shared copy of ACAD.LSP which uses
individually customized LISP configurations for each user.
Is there some sort of Developer organization which attempts to coordinate
such stuff?

Dave – Well, since I could give you the bottom line of that long discussion
from memory, much faster than I could dig it up, I'll do that. The basic
problem is multiple applications that contend for definition of C:XXXX and
the S::STARTUP function. To put it simply, they can't coexist without some
changes. In the case of S::STARTUP, what I recommend is that no application
attempt to define it, and instead, each application puts the name of the file
containing its startup code into an ascii file (call it 'INIT.LSP' if you wish)
Along with that, the following is the only thing that needs to be placed in
ACAD.LSP:
(defun S::STARTUP ()
(cond ( (not (findfile "INIT.LSP")))
(t (setq init (open "init.lsp" "r"))
(while (setq lspfile (read-line init))
(cond ( (or (findfile lspfile)
(findfile (strcat lspfile ".lsp")))
(load lspfile))))
(close init)))
)
In the case of two or more applications that attempt to redefine the same
AutoCAD command and replace it with their own version, things are just not
that simple, and this will require some intergration, to modify and/or to
combine each application-defined command replacement into one. I can't give
you any advice here, because each case must be dealt with individually, and
there are no general guidelines to follow.
If you have problems relating to the latter issue, than feel free to bring
them up here, and I'm sure you'll get plenty of help and/or advice.
