Change left or right indent via script

[Ghoul Fool]

So this is a bit puzzling:

app.activeDocument.activeLayer.textItem.leftIndent = new UnitValue(10, 'pt');

Doesn't appear to do anything. Whereas something similar 

app.activeDocument.activeLayer.textItem.contents = "spoon";

changes the text layer's contents to "spoon".

So...how do you change the indent size with code??

Where did you get .leftIndent from?

Edit: I found it - https://theiviaxx.github.io/photoshop-docs/Photoshop/TextItem/leftIndent.html#textitem-leftindent

Sometimes it's just better to enter the value without a unit of measure, then wrap the entire code or block in a unit of measure.

But I haven't had time to try...

I've already tried

var srcDoc = app.activeDocument;
var theLayer = srcDoc.activeLayer;
var left = new UnitValue(10, 'pt');
theLayer.textItem.leftIndent = left; // Does nothing
theLayer.textItem.contents = "spoon"; // Changes text

What shows

alert(activeDocument.activeLayer.textItem.leftIndent)

after operation?

I have everything working

0 pt by alert and on the paragraph tab.

Strange. Something broke.

Or leftIndent or UnitValue.

What does alert(new UnitValue(10, 'pt')) show?

Doesn't work on all fonts and layers, or just your specific layer and file?

I have now had time to test and get the same results.

The only success I had was to use AM code.

set(10);

function set(startIndent) {
    function s2t(s) {
        return app.stringIDToTypeID(s);
    }
    var descriptor = new ActionDescriptor();
    var descriptor2 = new ActionDescriptor();
    var reference = new ActionReference();
    reference.putProperty(s2t("property"), s2t("paragraphStyle"));
    reference.putEnumerated(s2t("textLayer"), s2t("ordinal"), s2t("targetEnum"));
    descriptor.putReference(s2t("null"), reference);
    descriptor2.putInteger(s2t("textOverrideFeatureName"), 808464435);
    descriptor2.putUnitDouble(s2t("startIndent"), s2t("pixelsUnit"), startIndent);
    descriptor.putObject(s2t("to"), s2t("paragraphStyle"), descriptor2);
    executeAction(s2t("set"), descriptor, DialogModes.NO);
}

Stephen,

Thank you, that works!

However, the bigger question remains: why doesn't the original code work. 

So mysterious...

It must have worked at one time, who knows how long it's been broken?
