Script to populate the file info from Paragraph Styles?

[LynxKx]

Is there a way auto-populate the file info of my document using paragraph styles? basically like variable text.

or is there a script that would fill in the file info with text that is assigned a paragraph so i could run the same script on multiple documents but it will fill in the doc specific info?

app.activeDocument.metadataPreferences gives to access to the File Info. So I'm thinking you could use FindGrep() to get the contents of the first paragraph using your main_title style, and copy it to app.activeDocument.metadataPreferences.description, for example.

I found some language that looks like it should work ... but gives me an error, any thoughts on how to fix?

var myDoc = app.activeDocument;
var docTitle ="";
var docDesc ="";
var docKeywords ="";
var docCopyright ="";

app.findGrepPreferences = app.changeGrepPreferences = null;
app.findGrepPreferences.findWhat = '.+';
found = app.activeDocument.findGrep (true);
for (j = found.length-1; j >=0 ; j--){

    
var foundText = found.contents;
    if(found.texts[0].appliedParagraphStyle.name == "main_title") {
         docTitle=found.contents;
     }
    else if(found.texts[0].appliedParagraphStyle.name == "metadata_desc") {
         docDesc=found.contents;
     }
    else if(found.texts[0].appliedParagraphStyle.name == "metadata_keywords") {
         docKeywords=found.contents;
     }
    else(found.texts[0].appliedParagraphStyle.name == "metadata_copyright") {
         docCopyright=found.contents;
     }
}

with (myDoc.metadataPreferences){
    documentTitle = docTitle;
    copyrightNotice = docCopyright;
    copyrightStatus = CopyrightStatus.yes;
    description = docDesc;
    keywords = [docKeywords];

    }

found is an arraty so you need to use the subscript operator to reference the items within the array. Try the following

var myDoc = app.activeDocument;
var docTitle = "";
var docDesc = "";
var docKeywords = "";
var docCopyright = "";

app.findGrepPreferences = app.changeGrepPreferences = null;
app.findGrepPreferences.findWhat = '.+';
found = app.activeDocument.findGrep(true);
for (j = found.length - 1; j >= 0; j--) {
    if (found[j].texts[0].appliedParagraphStyle.name == "main_title") {
        docTitle = found[j].contents;
    }
    else if (found[j].texts[0].appliedParagraphStyle.name == "metadata_desc") {
        docDesc = found[j].contents;
    }
    else if (found[j].texts[0].appliedParagraphStyle.name == "metadata_keywords") {
        docKeywords = found[j].contents;
    }
    else (found[j].texts[0].appliedParagraphStyle.name == "metadata_copyright") {
        docCopyright = found[j].contents;
    }
}
with (myDoc.metadataPreferences) {
    documentTitle = docTitle;
    copyrightNotice = docCopyright;
    copyrightStatus = CopyrightStatus.yes;
    description = docDesc;
    keywords = [docKeywords];

}

Thank you so much! I'm still learning to understand arrays!

Another suggestion, you might wanna use the appliedParagraphStyle property of findGrepPreferences to find the text with the required paragraphstyle instead of looping on all the text in the document.

Also reset the findGrepPreferences at the end

app.findGrepPreferences = null;

that is a good idea! thank you!
