Add Support Paths via LISP

[DoubleD]

I know this must have been asked many times before but I need to add 2 or 3 support paths to the support folder search paths but I want to do this via a lisp routine that can be added to my acaddoc.lsp, the added folders need to be listed as the first folders in the search paths..any help.

Have you seen the AutoLISP Forums? There is a recent thread, "Get the current support paths and add new paths" with this simple solution.

You might also check out AUGI's Publications. Some past articles of AUGI HotNews contain some information on Controlling Customization.

Hi "david.5774" ( Sorry, I do not know your real name )

Please note I have *moved* this thread from the AutoCAD General forum to this one, as I feel this particular forum is a more appropriate place for such a topic.

Thanks, Mike

What am I doing wrong here and how can I have it check to see if the path exists, and if it does, do not add it?

(defun c:addpath ()
(SETQ ORIGPATH (STRCAT (GETENV "ACAD")";"))
(SETQ ONEPATH (STRCAT "C:\\TEST"))
(SETQ MYENV (STRCAT ORIGPATH ONEPATH))
(SETENV "ACAD" MYENV)
(strlen (getenv "ACAD"))

Your (defun) is missing the closing parenthesis.

To check for the existance of C:\TEST you can do this:

(vl-load-com)
(setq *files* (vla-get-files (vla-get-preferences (vlax-get-acad-object))))
(SETQ ORIGPATH (vla-get-SupportPath *files*))
(SETQ ONEPATH (setq w ";C:\\TEST"))
(if (not (vl-string-search w ORIGPATH))
  (progn
    (SETQ MYENV (STRCAT ORIGPATH ONEPATH))
    (if (< (strlen myenv) 1000); <- not sure why you are checking the length
                                         ; I've seen something referring to 800 chars
                                         ; but my normal path is over 900 and I have no problems
      (vla-put-SupportPath *files* myenv)
    )
  )
)

That is not foolproof though, If you have a path such as C:\TEST\DIR\DIR, it would still find it because it's just searching for C:\TEST. I suppose you could test for C:\TEST;, but you can't count on the ";" being there if this is the last path in the list.

Also, note that if you add a path that doesn't exist, it will show up in the OPTIONS dialog, but it will not show up when you query the current path via code.
