UL_TEXT value resolves

Hi Chuck

 

I have no idea why the CHANGE command can recover the original text but

UL_TEXT cannot.

It  works differently in version 4 than it does in v5 and v6

In v4  CHANGE  TEXT reveals the resolved text as you see it on the board.

You dont get to see  >DRAWING_NAME  again once its been resolved for the

initial placement on the board. It is active though because if you change

the board file name the text changes with it, after a refresh.

 

It's an easy job to code your ULP to calculate what  >DRAWING_NAME will

resolve to so you can test for that and not  >DRAWING_NAME

Warren,

That's exactly what I've had to do.  Just for brevity, below are some

code snippets.

We usually keep the part number of each board encoded in the board's

file name, such as "513456.brd".  We use this to place the board's file

name in copper or silkscreen.  So with a board in hand, it's relatively

easy to quickly identify it and the schematic/drawing from whence it

originated.

As soon as it gets saved as "xxx-Array", the resolved text expands to

interfere with other board elements (component names if the text is on

the silkscreen, or traces, pads, smd's, vias if the text is on a copper

layer).  What passed DRC as the original file name, now has clearance

and overlap errors.  So part of the panelization ULP converts anything

based on the file name to just the base part number.

It's not the perfect way to do it, but it works for now.

Thanks for your input.

B/R,

    board(B) {

        //

        // Extract the base part number.  This really should be

        // a project level attribute, but for the time being, just

        // pull everything in the file name up to but not including

        // the first dash.

        //

        int dashIndex = strchr(filename(B.name), '-');

        if (dashIndex > 0)

            drawing = strsub(filename(B.name), 0, dashIndex);

        else

            drawing = filesetext(filename(B.name), "");

        ...

        //

        // Convert the drawing names to the base drawing number

        //

        cmd += "display none 21 22 1 16;\n";

        B.texts(T) {

            if (T.layer == 21 || T.layer == 22      // tplace or bplace

             || T.layer ==  1 || T.layer == 16) {   // or top or bottom

                /*

• For some reason, this does not work properly

• T.value is the resolved string.

                 *

• if (T.value == ">DRAWING_NAME") {

                 *

• The workaround is below.

                 */

                if (strsub(T.value, 0, strlen(drawing)) == drawing) {

                    sprintf(tmp, "change text '" + drawing + "' (%f %f);\n",

                        u2mil(T.x), u2mil(T.y));

                    cmd += tmp;

                }

            }

        }

        cmd += "display last;\n";

        ...

        exit(cmd);

If I just spin through all the text elements on a layer, the T.value

has already resolved to "513942".

 

board(B) {

    B.texts(T) {

        if (T.layer == 21) {

            sprintf(buf, "Text found in layer %d: %s.",

T.layer, T.value);

            dlgMessageBox(buf);

            if (T.value == ">DRAWING_NAME") {

                dlgMessageBox("Drawing name found in layer.");

            }

        }

    }

}

 

I get several message boxes with "Text found..." (appropriately).

What's displayed is "513942", not ">DRAWING_NAME".

 

The goal is to take this board and save it as 513942-Array.brd.  In

this case, all the drawing name texts become "513942-Array".  I want

the ULP to spin through the texts and produce script to replace all

the occurrences of ">DRAWING_NAME" with "513942".

 

The problem is that the value of the UL_TEXT object has already

resolved when the ULP is run.

 

Using the GUI, if i do a Change->Text, the string ">DRAWING_NAME"

shows up in the value.

 

So... why is the value different in the GUI that in ULP?

Hmmm... nope.  That didn't work either.

Good morning,

I have some text on the tPlace layer (21) of a board that has the value

">DRAWING_NAME".  In a ULP, the value of this element resolves to the actual

drawing name.  How can I get it's unresolved value?

board(B) {

    B.texts(T) {

        if (T.layer == 21 && T.value == ">DRAWING_NAME") {

            dlgMessagebox("Drawing name found in layer 21.");

        }

    }

}

The above code never presents a dialog box.

Ideas?

Thanks,

    - Chuck

In version 5.12, in a board editor,

If I specify the text value to be >DRAWING_NAME it immediately resolves to

the board name so I can never get >DRAWING_NAME on the board.

If I specify the text value to be ">DRAWING_NAME" I  get  it ">DRAWING_NAME"

on the board.

In the second case a ULP returns ">DRAWING_NAME"
