Script not reading values from input parameters correctly

Hello, 

below is most of the code which can magically add rules to columns and frames of differenent lengths.

there is a controller code which sets values the user puts in and then creates and xml 

and then there is the main code which can also use these xml values 

the purpose behind both scripts is the user can use the main script via shortcut with no dialogue box 

the controller script is working - and writes to xml file fine

but the main script doesnt seem to be able to get the right values for adjust top height or adjust bottom height 

it always over does it by either adding more is the user entered a positive value or takeing away too much if the user ended a negitive value 

Please may someone have a look as to what is making the main script not be able to read the controller script correctly

I have added the code below including the xml which is set up for adjust top height by 10 pt

Then the same result should happen when you run the main script which is suppose to read the values of the controller  -but it doesnt - it gives me this - much taller

The code is here 
Controller

var f = File($.fileName).parent + "/autoRule_user_preset.xml";

var xml = readXML(f);
if (xml == "") {
    xml = XML("<dialog><values><top>0</top><bottom>0</bottom><stroke>1</stroke><color>3</color></values></dialog>");
}

var tv = Number(xml.values.top); 	//var for topValue
var bv = Number(xml.values.bottom);	//var for bottom/Value
var sv = Number(xml.values.stroke); 	//var for strokeValue
var cv = Number(xml.values.color);	//var for colourValue

var t, b, s, c, cd;
makeDialog();

//Creates the box for user input

function makeDialog() {
    var d = app.dialogs.add({ name: "autoRule Controller  (。◕‿◕。)", canCancel: true });
    with (d.dialogColumns.add()) {
        staticTexts.add({ staticLabel: "Adjust top height:" });
        staticTexts.add({ staticLabel: "Adjust bottom height:" });
        staticTexts.add({ staticLabel: "Adjust stroke weight:" });
        staticTexts.add({ staticLabel: "Stroke color:" });
    }
    with (d.dialogColumns.add()) {
        t = measurementEditboxes.add({ editUnits: MeasurementUnits.POINTS, editValue: tv, minWidth: 50 });
        b = measurementEditboxes.add({ editUnits: MeasurementUnits.POINTS, editValue: bv, minWidth: 50 });
        s = measurementEditboxes.add({ editUnits: MeasurementUnits.POINTS, editValue: sv, minWidth: 50 });
        cd = dropdowns.add({stringList:getArrayNames(app.activeDocument.swatches.everyItem().getElements()), selectedIndex:cv, minWidth:80});

        s = s.editValue;
        //get the swatch object
        c = app.activeDocument.swatches.everyItem().getElements()[cd.selectedIndex];

        xml.values.bottom = b;
        xml.values.stroke = s;
        xml.values.color = cd.selectedIndex;//the selected dropdown number
        writeXML(f, xml.toXMLString());

    var f = new File(p);
    f.open("r");
    var t = f.read();
    f.close();
    return XML(t);
}





and the xml


<dialog>
  <values>
    <top>10</top>
    <bottom>0</bottom>
    <stroke>1</stroke>
    <color>8</color>
  </values>
</dialog>


Any ideas would be most helpful

 

thank you

Hopefully with a bit of work this can be solved.

 

All you have to do is add this as the first line

app.scriptPreferences.measurementUnit = MeasurementUnits.POINTS

 

And reset with this at the end

 

app.scriptPreferences.measurementUnit = AutoEnum.AUTO_VALUE;

The measurementEditboxes always return points even if the user specs some other unit, so your loaded XML numbers are points. You still have to either set the scripting measurement units or change the ruler units to points for the script without a dialog.

Hello, 

Thank you again for you advice. Was just staring at the code and finally got round to noticing that it has to be something to do with a data mismatch. Hopefully with a bit of work this can be solved. 

Have your tried the script by the way? 

Best, 

Smyth

Wow  - works like a charm. fixed. 

I think with that fix the script is now useable - until a week's time and I think of somethign else that should be incorporated. 

Many thanks for the advice, 

enjoy the rest of your weekend, 

Smyth

Your version with no dialog doesn’t work if the XML file is missing, you still need to provide a default XML string incase the XML is not there

 

 

// Load user-defined values from XML
var f = File($.fileName).parent + "/autoRule_user_preset.xml";
var xml = readXML(f);
if (xml == "") {
    xml = XML("<dialog><values><top>0</top><bottom>0</bottom><stroke>1</stroke><color>3</color></values></dialog>");
}

Yikes, good to note, at least this way a user doesnt have to always start out with the controller 😄

For exmple here the units are set to Millimeters with the starting value set to 10:

 

 

var x;
makeDialog();
function makeDialog(){
    var theDialog = app.dialogs.add({name:"Enter a Number", canCancel:true});
    with(theDialog.dialogColumns.add()){
        staticTexts.add({staticLabel:"X:"});
    }
    with(theDialog.dialogColumns.add()){
        x = measurementEditboxes.add({editUnits:MeasurementUnits.MILLIMETERS, editValue:10, minWidth:90});
    }

    if(theDialog.show() == true){
        x = x.editValue;
        main()
        theDialog.destroy();
	}
}


function main(){
    alert("Value Returned: " + x)
}

 

 

the initial dialog value is 3.528 mm (10 points)

 

Screen Shot 8.png

 

Set the value to 10 mm

Screen Shot 9.png

 

and the returned value is 28.346566929134 points
