SOLVED: How do I set an attribute on all parts on a single schematic sheet?

Looks like attrib-add108.ulp is the answer.  Select the group of parts, then run that ULP.

Thanks to George at US tech support for pointing it out and to Bob Starr for writing it...

The attrib-add script does what I needed it to do, but just for grins I kept at it on my own ULP, and I figured I'd throw it up here to see if anybody else could use it as a template.  I certainly don't think it's good enough to waste on an upload to the ftp site.  Just modify the "ATTRIBUTE" line if you want to do something else to each part...

EDIT:  Looks like there are actually a couple problems with this script.  It seems that only the parts on the first sheet get the attributes.  I've played around with adding sprintf(tmp, "edit .s%d;\n", S.number); and Script += tmp; before the commands for each page, but then when I run the script, EAGLE crashes.  Weird!  It's the only time I've ever seen EAGLE crash.  My first guess is that the Script gets too big and overflows some buffer on exit().  I need to learn about the output command so that I can create the script in a text file and then run it...  -DDW 20121129

#usage "<b>Adds PAGE number attribute to each part on each page of a schematic.</b>";

 

string Version = "0.10";

string tmp = "";

string Message = "";

string Script = "";

 

if (!schematic) {

  dlgMessageBox("Start this ULP from a Schematic...", "OK");

} else {

  schematic(SCH) {

    sprintf(tmp, "Schematic Name:\n%s\n", SCH.name);

    dlgMessageBox(tmp);

    SCH.sheets(S) {

      sprintf(Message, "Sheet %d\n---------\nParts:\n", S.number);

      S.parts(P) {

        sprintf(tmp, "%s\n", P.name);

        Message += tmp;

        sprintf(tmp, "ATTRIBUTE %s PAGE '%d';\n", P.name, S.number);

        Script += tmp;

      }

    dlgMessageBox(Message);  // Dialog box with list of parts on page

    }

  }

  //dlgMessageBox(Script);  // Debugging - show script before executing

  exit(Script);

}

I wish each sheet had it's own text name instead of just a number, but that is because I'm still on version 5.  (Looks like version 6 includes both a "headline" and a "description"...)

perhapse you can use an attribute atttached to a frame (if you have

page frames)

Yep, I modified my script to use output() and wrote all the commands into a file and then I ran the file manually after the ULP finished, and it worked!

I even managed to crash things with Bob's script on a couple pages of my schematic, so I must have enough parts to fill up whatever buffer exit() uses...

Next, I just have to figure out how to get exit() to call my script properly.  The fun continues!

Sheet names would be nice.  In the mean time, have you tried:

    schematic(SCH) {

       SCH.sheets(S) {

          if (S.number == sheetOfInterest) {

             S.instances() {

                ...

             }

          }

       }

    }

or:

    schematic(SCH) {

       SCH.parts(P) {

          P.instances(I) {

             if (I.sheet == sheetOfInterest) {

                ...

             }

          }

       }

    }

I think that either of these can filter by sheet.

Take a look at the 6.2 ULP docs for UL_PART.  It talks about the

instances() loop member in the notes.

    /If the part is in a sheet context, the instances() loop member

    loops only through those/

    /instances that are actually used on that sheet. If the part is in a

    schematic context, all instances are/

    /looped through./

Also, look at the example under UL_INSTANCE

    Example

    schematic(S) {

      S.parts(P) {

        printf("Part: %s\n", P.name);

        P.instances(I) {

        if (I.sheet != 0)

          printf("\t%s used on sheet %d\n", I.name, I.sheet);

        }

      }

    }

Thanks Chuck, I was thinking that it would be nice to have names for each sheet in the GUI instead of just sheet numbers.  Version 6 does indeed have that.  In my ULP, it's pretty simple to have an array of names indexed by sheet...

Now, I just ran into something incredibly silly!!!

export partlist

is the command that I needed the whole time!
