How to prevent duplicate cell creation?

kumarb
Hi Experts, I wrote the following SKILL to prevent duplicate cell creation while creating new cell in any of the project library.==============================procedure(DuplicateCellChk(@rest args) let((libList libName cellName tmpPath (cells_with_same_name nil))    if(car(reverse(args))=="ddViewType"   then  tmpPath=cadr(args)  libName=car(args)~>lib~>name  cellName=car(parseString(tmpPath "/"))  libList=ddGetLibList()    ;;ignoring lx*SCRATCH  temp cells   if(!rexMatchp("^lx[a-zA-Z0-9]*SCRATCH$" cellName)  then    foreach(lib libList     if(member(cellName lib~>cells~>name) then      cells_with_same_name=cons(lib~>name cells_with_same_name)      );if    );foreach   ); if SCRATCH cell check    if(length(cells_with_same_name)>1 then    if(ddGetObj(libName cellName)~>views then         hiDisplayAppDBox(                    ?name gensym('dialogBox1)                    ?dboxBanner "Warning!"                    ?dboxText  strcat("Duplicate cells exists with the name " cellName " in Libraries " sprintf(nil "%L" cells_with_same_name))                    ?buttonLayout 'Close                        );DBox                          else  ddDeleteObj(ddGetObj(libName cellName))     hiDisplayAppDBox(                    ?name gensym('dialogBox1)                    ?dboxBanner "Error!"                    ?dboxText  strcat("Can't create cell " cellName " as this already exists in libraries " sprintf(nil "%L" remd(libName cells_with_same_name)))                     ?buttonLayout 'Close                        ) ;DBox       error("\n")    );if   );if  );if t ) ;let);procddRegTrigger("PreCreateObj" 'DuplicateCellChk)========================================== This code works as far as cell creation is concerned. But, this is causing problem while instantiating pcells in the layout since function is being triggered on each object creation due to PreCreateObj. So, when I try instantiating pcell, submaster is created in VM and hence function triggers. So, this is not a practical solution. I only want to put check at the time to cell creation not all other object creation.  I need to put this check since out verification scripts expect unique cells in all the cds.lib. Do we have hook called PreCreateCell? Thanks in advance for the suggestions. Best Regards,Bhupendra

  • Hi Bhupendra,

    Code formatting/line-wrapping makes it impossible to debug. I suggest you compare against the cellName being "^zpcell.*" or "^zvia.*" to filter out the pcell ghost scratch cellViews. You should also be able to limit the check when  just a ddCellType is being created, but can't really see your code to make clearer  suggestions.

    Regards,

    Andrew.
