Google apps script - Speeding up getActiveDocument()?

Question

I'm working on a script to set to uppercase a selected text in a Google document. The script works ok, but it is extremely slow in a large document. So I stripped down almost everything to perform some speed test and I realised that this simple line:

      var document = DocumentApp.getActiveDocument();

already takes 9-10 seconds to perform for a 150 pages document.

Is there a way to speed up the process, i.e. precaching "document" so that when I invoke my script I can use my getCursor() or getSelection() in a reasonable time?

Answer 1

You can't precache this. The services provided for caching are:

• CacheService : only store String values
• ScriptDB : can't store Document on this.

So I'm afraid that you will need to cope with it.
