Hi Roman, I haven't done this with ExtendScript, but in FrameScript you have to programmatically open each corresponding document in each book and run the compare at the document level. I think that is the only way to get the level of detail that you normally get from the GUI. You could check the FDK docs and see if there are more details about the process. -Rick
I considered running doc.compare() as you've mentioned, but I first wanted to see if this function works at the book level. It seems that it doesn't.
It's not clear to me how to further utilize the CompareRet object that is the result of the function execution. I've checked the corresponding FDK function, but of course the syntax in this IDE is different and I am not sure if a working example is provided there.
It's a pity that the Adobe guys do not monitor this forum and don't answer questions as well. Shame...
