Get Working RGB/CMYK in Illustrator with ExtendScript without Open Doc

oops, my bad, I misunderstood the assignment.

try this version, if you start with an open document, the script won't need to create the temp doc

// get color profiles, both rgb and cmyk
// carlos canto

function getProfile() {

    var deleteDoc = false;

    if (app.documents.length > 0) {
        var doc = app.activeDocument;
    }
    else {
        var doc = app.documents.add(DocumentColorSpace.CMYK, 1, 1);
        deleteDoc = true;
    }

    var order = [0, 1]; // use to tell whether doc is rgb or cmyk and to switch color modes
    var colorSpaces = [DocumentColorSpace.RGB, DocumentColorSpace.CMYK];
    var commands = ["doc-color-rgb", "doc-color-cmyk"];
    var profiles = [0,1];

    // get color mode and profile
    var colorSpace = activeDocument.documentColorSpace; 
    var profile = activeDocument.colorProfileName;

    // save the profile in the righ order
    if (colorSpace == colorSpaces[1]) {
        order.reverse();
        profiles[1] = profile;
    }
    else {
        profiles[0] = profile;
    }

    // change color mode
    app.executeMenuCommand (commands[order[1]]);

    profiles[order[1]] = activeDocument.colorProfileName;

    // reverse color mode to its original mode
    app.executeMenuCommand (commands[order[0]]);

    // delete temp doc if any
    if (deleteDoc) {
        activeDocument.close(SaveOptions.DONOTSAVECHANGES);
    }

    return profiles;
}

var profiles = getProfile();

alert("\nRGB Profile:\n" + profiles[0] + "\n\nCMYK Profile:\n" + profiles[1]);

Here’s one way to get the document color mode without opening the files. If your ai files have swatches in them, we could use the swatches color mode in the XMP metadata.

Here’s a working Illustrator sample script. I have plenty of comments let me know if you have additional questions

place a couple of ai files in a folder before running the script

// get file color mode without opening the file
// carlos canto 2/12/26

/* method
    - select folder
    - get ai files
    - get xmp
    - serialize xmp object into String
    - convert string to XML
    - get first Colorant (color) Mode ("xmpG:mode") - Colorants are swatches in the document
*/

function main() {
    //var f = new File(File.openDialog("chose file"));
    var aiFolder = new Folder(Folder.selectDialog ("Select Folder with Illustrator Files"));

    //var aiFolder = "/c/temp";

    // load the XMPScript library
    if (ExternalObject.AdobeXMPScript == undefined)
    ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript');

    // go through the files in the folder
    var aiFiles = aiFolder.getFiles("*.ai");

    for (f in aiFiles) {
        var file = aiFiles[f];

        // applies only to files, not to folders
        if (file instanceof File) {
            var xmpFile = new XMPFile(file.fsName, XMPConst.UNKNOWN, XMPConst.OPEN_FOR_READ);
            var xmp = xmpFile.getXMP();

            var xmpString = xmp.serialize();

            xmpFile.closeFile(XMPConst.CLOSE_UPDATE_SAFELY);

            var xmlObj = new XML(xmpString);
            var swatchesMode = xmlObj.descendants("xmpG:mode");

            alert (file.fsName + "\n\nColor Mode: " + swatchesMode[0]);

        }
    }
}

main();
