Tengo una persona que busca contar páginas de quizás 2-3000 PDF. Necesita un recuento total de todos los archivos PDF combinados (probablemente ascenderá a algo así como 20 000 repartidos entre los 3000 archivos PDF); no se necesitan más detalles.
Consideré Adobe Combine y luego obtuve un recuento de páginas, pero solo probando en ~ 500 archivos, ¡es bastante lento!
¡Vale la pena mencionar que solía poder abrir varios archivos PDF simultáneamente en la vista previa y obtener un recuento de páginas! ¡Solía funcionar bastante bien, incluso en 2-300 archivos!
Gracias por tus pensamientos.
Simple.
Cree un Apple Script y expórtelo como una aplicación y luego envíele la aplicación.
Código AppleScript:
set totalPages to 0
set numDocs to 1
set myFiles to choose file with prompt "Select all PDF's" with multiple selections allowed
set nummyFiles to length of myFiles
set progress total steps to nummyFiles
set progress completed steps to 0
set progress description to "Processing PDF's..."
set progress additional description to "Preparing to process."
repeat with i in myFiles
set progress additional description to "Processing PDF " & numDocs & " of " & nummyFiles
set progress completed steps to numDocs
set myfile to POSIX path of i
set pageCount to (do shell script "/usr/bin/mdls " & quoted form of myfile & " | /usr/bin/awk '/kMDItemNumberOfPages/{print $3}'") as integer
set totalPages to (totalPages + pageCount)
set numDocs to (numDocs + 1)
end repeat
display dialog "There are " & totalPages & " pages in this PDF"
/Applications/Utilities/Script Editor.app
myFiles
podría romperse con varios cientos de archivos seleccionados. 3,0000 es un montón de archivos. ¿Por qué no hacer que el usuario seleccione una carpeta y luego ejecute el bucle en el script de shell?Probé el enfoque de Josh usando mdls
y encontré una cantidad sorprendente de (nulos) para kMDItemNumberOfPages.
Así que cambié de rumbo y usé AppleScriptObjC para contar directamente las páginas en los archivos PDF encontrados.
El script se ejecutará directamente desde Script Editor.app o desde un subprograma de script.
Producirá un informe en TextEdit que se ve así:
--------------------------
PDF files found : 460
Total Pages : 27052
Total Errors : 0
--------------------------
Esta ejecución duró 10 segundos en mi MacBook Pro i7 de mediados de 2010 de 17".
La siguiente línea debe modificarse en el script para reflejar correctamente el directorio de destino en el sistema del usuario:
property searchPath : "~/Downloads"
(Aunque me encantaría que funcione en la ventana frontal del Finder si lo solicita).
Actualmente, el script está configurado para ser recursivo en el directorio de destino.

Como esta criatura solo se ha probado ligeramente, no doy garantías, pero hasta ahora estoy satisfecho con ella.
