Compare specific properties of two pdf files (beginner)

[tkittel]

Hello,



I've a flow, where incoming folders always contain two pdf files (only). In the 1st step, 'ungroup job' splits the pdf files out of their folder. In the 2nd step the modification dates of both pdfs should be compared and the prefix "top_" should be added to the newer one. The 3rd step, should move both pdf files back into their original folder using the 'assemble job' element.



What's the best way to realize step 2 ?



Thanks for help!

Your comparison will have to occur before the Ungroup. The two files will be in separate jobs and can't be (easily) compared.

Hello Dwight,



thanks for your info - I was afraid that it will not be easy.

I was able to create a script that performs the function you requested. Create a Scripted element with a single property named "prefix". Set the property to "out_" when you add Script to your flow.





function jobArrived( s : Switch, job : Job )

{

if (job.isFile()) {

job.sendToSingle(job.getPath());

} else {

var theJobDir = new Dir(job.getPath());

var theDirEntries = theJobDir.entryList("*.pdf", Dir.Files, Dir.Time);

var i;



for (i=0; i < theDirEntries.length; i++) {

var fileName = theJobDir.path + "/" + theDirEntries;

if (i==0) {

// rename the oldest file

var theFile = new File(fileName);

var theNewName = s.getPropertyValue("prefix", job) + theFile.name;

var outFilename = job.createPathWithName(theNewName, false);

s.copy(fileName, outFilename);

job.sendToSingle(outFilename);

job.sendToNull(fileName);

} else {

job.sendToSingle(fileName);

}

}

}

}

Hello Dwight,



today I found your code, copied it to the switch script editor and created the script element for the prefix, how you noticed it. Well, what shall I say: "It works perfectly".

So I started to adapt some details and implemented it to my flow. Now I 'only' have to analyze it to understand, how it works ;o)

Thank you very much for this code!



Have a nice day!

Thomas
