[gentoo-user] Find ebuilds that use a flag

[James]

Hello,


I need to be able to find which packages use a particular flag.

"gpac" to be specific:

Enable GPAC support when exporting to 3GPP format.


Any simple/global tools to find and list each and every
package available on Gentoo that has this flag as a option?


There is also an ebuild named "gpac"

Kino is one package the has this "gpac" flag.
How so I know it is the only one that requires
this gpac flag?

You can use

equery hasuse gpac ==> shows all install packages which have

or

qgrep -v IUSE|grep gpac ==> extensive but should bring you all packages which have it in USE

Since it's a local use flag, I suppose 'euse -i gpac' should do the
trick. euse is a part of app-portage/gentoolkit package.

This only searches my installed base of software:



[ Searching for USE flag gpac in all categories among: ]
 * installed packages
[I--] [  ] media-video/kino-1.3.1 (0)


How do I search for ebuilds (packages) that have this flag
as an option, for all of the software I do not have installed?

euse -i gpac
global use flags (searching: gpac)
************************************************************
no matching entries found

local use flags (searching: gpac)
************************************************************
[-    ] gpac (media-video/kino):
Enable GPAC support when exporting to 3GPP format

OK, how do I know this is an exhaustive search of both packages installed
and other packages I do not have install on the system it is ran on?

Simple: you have to trust in euse :)

Also, I've noticed that there's q-analog of euse in
app-portage/portage-utils package: quse

'quse -e gpac' should give you pretty much what you need and should
work for both global and local use flags.

euse is often not correct in its output!!!

Using eix (emerge eix; update-eix):
eix -e -U gpac

Using equery:
equery hasuse -p -o gpac

-p meaning search portage tree
-o meaning search any overlays you might have

Listening to your hard drive grind away should convince you it's doing 
what you want. It should also convince you to use eix.


Either way you do it, media-video/keno is the only one
