How do I delete the wires in a layer by ULP?

fabiodl

I am new to ULP.

I can count how many wires there're in a layer by this code

 

int i=0;

string buff;

board(B) {

  B.wires(w) {

    if (w.layer==46){

      i++;

    }

    }

  }

sprintf(buff,"%d wires",i);

dlgMessageBox(buff);

 

 

What I would like is deleting the wires of layer 46 by a ULP. Is there any built in function for that? Something like

  delete(w)

?

If it is not possible, what other approach could I use to delete the content of a layer programmatically?

    ULPs are a bit... unexpected in that there are no facilities in the

    language for making any change at all to the design. You just can't.

     

    However, you can do something after the event. If your ULP passes a

    string to the "exit" function on completion, then Eagle will execute

    that string as if you'd typed it in the command box. So either

    accumulate all your deletion commands into a string and end with:

     

       exit(cmd);

     

    or write them to a script file and end with:

     

       exit("SCRIPT '" + scriptfile + "';");

     

    There are examples of both in the ULPs supplied with Eagle.

    Thank you, I tried looking at scripts. Still I didn't progress much.

     

    DISPLAY NONE 46;

    GROUP ALL;

     

    but then DELETE *, DELETE ALL or DELETE GROUP do not seem to exists. Do you know any command that serves the purpose?

    Check the help, under "Editor Commands -> Command Syntax"

     

    If you were doing this operation by hand, you would set only layer 46

    shown, select the group tool and sweep over the whole lot. That much you

    have done. Then you would select the delete tool and click the right

    mouse button (with the control key if you're on the V5 user interface -

    I'm still mostly using V4.15) anywhere on screen.

     

    That help page explains the syntax, but for "delete tool

    ctrl-right-click" you want:

     

    DELETE (C> 0 0);
