Create new doc if is not already open

[siomosp]

I am trying hours without success..

I want to create a new document, if it is not already an opened document with the same name

The following always creates another document Temp100x70.psd, even if a Temp100x70.psd is already open

What I am doing wrong!

var originalUnit = app.preferences.rulerUnits;
preferences.rulerUnits = Units.CM;

var fName= "";

for (var i = 0; i < app.documents.length; i++) {
    var fName = app.documents[i].name
  if(fName.match(/(.*Temp100x70.psd).*/i)) { 
        app.activeDocument = app.documents.getByName(fName)
  } else {
 app.documents.add(100, 70, 72, "Temp100x70.psd")
 break;
} }

Unless the file is saved already, it doesn't exist. That's one of those quirks you have to account for.

@Mylenium – I don't believe that is it as @siomosp isn't using .path() or .fullName() in the code.

[siomosp]

I think @Mylenium  is right
Similar code works fine for an existing file

var myFileList = [
    'C:/BackgroundsSync/_usefull/Temp100x70.psd',
    'C:/Temp100x70.psd'
];
for (var i = 0; i < app.documents.length; i++) {
    var fName = app.documents[i].name
    if(fName.match(/(.*Temp100x70.psd).*/i)) { 
        app.activeDocument = app.documents.getByName(fName)
    } else {
        for (var a in myFileList) {
            var currentFile = new File(myFileList[a])
            if (currentFile.exists) {
                app.open(currentFile)
                break;
            };
        }
    }
}

Anyway, if someone finds another solution, it would be great

I haven't had any success either.

The following lists all open docs, one by one by name, whether they are saved or not, which is why I was thinking that it shouldn't matter whether the file has been saved.

for (var i = 0; i < documents.length; i++) {
var theDoc = app.documents[i];
app.activeDocument = theDoc;
    alert(theDoc.name);
}

@siomosp – Does this work for you? I have tested with unsaved docs:

/*
https://community.adobe.com/t5/photoshop-ecosystem-discussions/create-new-doc-if-is-not-already-open/td-p/13428283
*/

#target photoshop;

if (documents.length) {

	// Set the open documents name variable
	var theNames = getDocInfo().join(",");

	//alert(theNames);
	//$.writeln(theNames);

	// Test the open documents array for an open doc named: Temp100x70.psd
	if (/Temp100x70.psd/i.test(theNames)) {
		// Do nothing...
		alert("The doc exists, do nothing!");
	} else {
		// Do something...
		alert("The doc doesn't exist!" + "\r" + "Create the temp doc...");
	}


	function getDocInfo() {
		/*
		Function modified from the original by Supermerlin:
		https://community.adobe.com/t5/photoshop-ecosystem-discussions/get-list-of-all-photoshop-documents/m-p/9552414
		*/
		var IDs = new Array();
		var count = app.documents.length;
		for (var a = 1; a < count + 1; a++) {
			var ref = new ActionReference();
			ref.putIndex(charIDToTypeID('Dcmn'), a);
			var desc = executeActionGet(ref);
			var Title = desc.getString(stringIDToTypeID('title'));
			IDs.push([
				Title
			]);
		}
		return IDs;
	}

} else {
	alert("A document must be open to run this script!");
}

Edit:

And here it is in standard DOM code rather than AM code:

/*
https://community.adobe.com/t5/photoshop-ecosystem-discussions/create-new-doc-if-is-not-already-open/td-p/13428283
*/

#target photoshop;

if (documents.length) {

	// Set the open documents name variable
	var theNames = getDocName().join(",");

	//alert(theNames);
	//$.writeln(theNames);

	// Test the open documents array for an open doc named: Temp100x70.psd
	if (/Temp100x70.psd/i.test(theNames)) {
		// Do nothing...
		alert("The doc exists, do nothing!");
	} else {
		// Do something...
		alert("The doc doesn't exist!" + "\r" + "Create the temp doc...");
	}


	function getDocName() {
		var IDs = new Array();
		var count = app.documents.length;
		for (var a = 1; a < count + 1; a++) {
			var Title = activeDocument.name;
			IDs.push([
				Title
			]);
		}
		return IDs;
	}

} else {
	alert("A document must be open to run this script!");
}

Hi!

The AM code detects the name Temp100x70.psd if exists

But how can I activate it ?

[Stephen_A_Marsh]

Both the DOM and AM code should detect the name.

To activate, do similar to what you were originally doing, this time using a string rather than a variable:

	// Test the open documents array for an open doc named: Temp100x70.psd
	if (/Temp100x70.psd/i.test(theNames)) {
		// Set the active document...
		activeDocument = documents.getByName("Temp100x70.psd");
	} else {
		// Create the temp doc...
        documents.add(100, 70, 72, "Temp100x70.psd");
	}

P.S. I think you need to look into the code for documents.add() to see if it performs as you expect...

Edit – Here it is in full, just in case the documentation isn't clear:

documents.add(UnitValue(100, "px"), UnitValue(70, "px"), 72, "Temp100x70.psd", NewDocumentMode.RGB, DocumentFill.WHITE, 1, BitsPerChannelType.EIGHT, "sRGB IEC61966-2.1");

You can sometimes use a value of null or undefined instead.

The name is detected, (only with your first AM code, not in your second standard DOM code) but I need to activate the temp100x70.psd, when the active document is another document

Actually, I did it, modifying the https://stackoverflow.com/questions/67467344/find-item-from-an-array-adobe-cep
It is "kindergarten" code, but works

app.preferences.rulerUnits = Units.CM;
// Set the open documents name variable
	var theNames = getDocInfo().join(",");
	// Test the open documents array for an open doc named: Temp100x70.psd
	if (/Temp150x70.psd/i.test(theNames)) {

var array = new Array(theNames);
var found   = "";
var sample  = "Temp150x70.psd";
var counter = 0;
while (counter<array.length) {
  if (array[counter] = sample) {
    found = sample;
    break;
  }
  counter++;
}

if (found != "") {
	app.activeDocument = app.documents.getByName(found)
} else {
//  alert("Nothing was found");
}	
	
	} else {
	// Do something...
	 app.documents.add(150, 70, 72, "Temp150x70.psd")
	}
			}
