Check what will an USE flag pull in?

[midnite]

Take kde-apps/kdesdk-meta as an example. By default all its USE flags are disabled. Installing kde-apps/kdesdk-meta with default USE flags options almost install nothing.

Thanks both pietinger and Genone for reply.

Sorry if I caused the confusion.

Before the USE flag was enabled, USE='webengine' emerge -pv kde-apps/kdesdk-meta would list the packages going to be emerged, (This output is quoted from my first post):

equery d doesn't filter its output according to active USE flags.

So once the most recent package install has pulled any new package,
equery d will report about any installed package which COULD require such new package to be installed.

It would be indeed be nice if equery could only report packages which DO require new package installed according to their current settings.

Thks 4 ur attention, interest & support.

Ok, it was a language issue. Your question is "How to check what packages were pulled in due to a specific USE flag?"
That is a complex topic. In your example, kdevelop-php and kdevelop-python were pulled in by USE=webengine, but only because you also had set USE="php python". And other relationsships are even more complex. Properly resolving all that in reverse and displaying it in a usable way is quite tricky.
