Merging PDF pages

[panagiotis m]

Hello all,

There is a built-in utility on MacOS for merging PDFs. You can call it from
"shell", as Paul suggested.

This seems to work - tested on MacOS Mojave. It merges "test1.pdf" and
"test2.pdf" into "merged.pdf" on Desktop.
Just check that the path of tApp actually exists in modern MacOS as well.

on mouseUp pButtonNumber
   local tShell, tApp
   put quote & "/System/Library/Automator/Combine PDF
Pages.action/Contents/Resources/join.py" & quote \
         into tApp
   put tApp && "-o ~/Desktop/merged.pdf ~/Desktop/test1.pdf
~/Desktop/test2.pdf" \
         into tShell
   get shell(tShell)
end mouseUp

Cheers,
Panos
