Need help Scripting

[eddiee1993]

   I am a beginner at scripting, coding, and web design. I have been having questions regarding scripting.

I need help developing an Adobe Script that will 1)Automatically open a PDF file I have (created in Illustrator CC 2015)

                                                                              2) Automatically change the name of two swatches,  to new names I have

                                                                              3) Save with same file name plus "_Z.PDF" at the end

                                                                               4) Then close the file.

So you mean you've saved all your pdf file with "Preserve Illustrator Editing Capabilities" option checked on? You can start from here.

// 1)
var f = new File('path/to/filename.pdf');
var doc = app.open(f);
// 2)
doc.swatches.getByName('swatch_1').name = 'new_swatch_1';
doc.swatches.getByName('swatch_2').name = 'new_swatch_2';
// 3)
doc.saveAs(new File(f.fsName.replace(/\.pdf$/, '_Z.pdf')), new PDFSaveOptions());
// 4)
doc.close();

Thank you very much for your time and help. I tried running the script this way below but it says

there is still an error in the part :  var doc = app.open(f);

What should I do about this? I have it underlined below too in bold italics.

function test()

{

    // 1) 

    var thePath = "~/Desktop/";

    var theFile = "test_swatch_change.pdf";

    var f = new File(thePath + theFile); 

    var newFileName = theFile.replace(/\.pdf$/, "_Z.pdf");

   var doc = app.open(f);

    // 2) 

    doc.swatches.getByName('Kiss Cut').name = ('CutContourKiss-cut'); 

    doc.swatches.getByName('Through Cut').name = ('CutContourThru-cut'); 

    // 3) 

    var saveFile = new File(thePath + newFileName);

    var saveOpts = new PDFSaveOptions();

    doc.saveAs(saveFile, saveOpts); 

    // 4) 

    doc.close(); 

}

test();

Just works fine here.

try { var doc = app.open(f) } catch (e) { alert(e) }

what's the error info?

[eddiee1993]

It says its not a function. I think its app.open that they are referring too.

Oh no, did you run it from ESTK and had not set target to illustrator?

[eddiee1993]

yes, it wasnt going through
