How to use a single undo to undo a script which contains multiple sub-actions.

[philipc45437321]

Hi,

I had expected there to be lots of people asking this so that suggests that it's either very easy and I am being dumb or it's very hard and that's why no one is trying it.

I would like to run a Javascript function in Photoshop which contains multiple sub-actions. The script runs fine but when I undo I have to undo once for each sub-action to get back to me original state.

How do I run a script so that the entire script counts as a single undo?

Thanks

Either create a snapshop and revert back to it or use suspendHistory()

if(documents.length) app.activeDocument.suspendHistory('History Name', 'functionName()');

Perfect, thanks!

can you use the same for InDesign? If so, where do you add into the script?
