@robby Is there a way to programmatically deactivate background expansion?

(I need to get the activation state, deactivate for a while, do some work, then reactivate it if it was activated)

It looks like (preferences:set 'drracket:online-compilation-default-on #f) should disable it.

Setting the preference is the same as clicking on the little bubble and choosing the menu item that appears. Using preferences:get tells you what state it is in.

Perfect, thanks!
