Auto page numbering

In reference to your question about auto page numbering:

Yes, you can change page numbering using scripting. You can also change the auto page numbering manually from the pages panel: From the list of pages in the document, select the page at which you want to change numbering. Then, from the pages panel's contextual menu (little down arrow at top right) select numbering and section options. This dialog is pretty self explanatory. Check Start Section, and Start Page Numbering at. Enter the number for the page.

If you combine your documents into a book (File > New > Book), you can update the page numbering from the Book's contextual menu. Select Update Numbering, then Update Page and Section Numbers.

With scripting the process is similar: you can create sections and indicate where the section will start, what the page number will start with, and so on. The following is for AppleScript, ExtendScript will be similar.

tell application "Adobe InDesign CC 2014"

   set docRef to document 1

   tell docRef

      set pageRef to page 1 of spread 1

      set sectionCount to count of sections

      if sectionCount > 0 then

         tell section 1

            set continue numbering to false

           set page start to pageRef

           set page number start to 1

        end tell

      else --if no sections exist

         make section with properties {name:"First", page number style:arabic, continue numbering:false, page number start:1, page start:pageRef, marker:"", length:8, section prefix:"", include section prefix:false}

      end if

   end tell

end tell

Hope this is what you needed.
