when i do for example code--> emerge -p gaim <--code i get: code--> pelux@gentoo pelux $ emerge -p gaim These are the packages that I would merge, in order. Calculating dependencies ...done! [ebuild UD] x11-libs/gtk+-2.0.9 [2.1.2-r0] [ebuild U ] net-im/gaim-0.59.6 [0.59.5-r0] <--code I would like to see something like this: code--> pelux@gentoo pelux $ emerge -p gaim These are the packages that I would merge, in order. Calculating dependencies ...done! [ebuild UD] x11-libs/gtk+-2.0.9 [2.1.2-r0] [ebuild U ] net-im/gaim-0.59.6 [0.59.5-r0] The following USE flags for this action are: [enable] java ..... [disable] compose .... [unset] noirc nomozmail ..... <--code The use flags printed out are ONLY concerning this emerge action so [enable] : use var presents in IUSE in ebuilds and enabled by the user [disable] : use var presents in IUSE in ebuilds and disabled by the user [unset]: use var presents in IUSE in ebuilds but not set by the user This is usefull for various reasons! A user are not supposed to know that flags like nomozmail exists! Also if a user find a use var under the unset group he will likely search for description for it. Maybe he forgot to set it. That would really be anice improvement! Thanks to Gentoo team! Stefano Peluchetti
Nice feature, I'd like to see this added as well.
obviosly the example is about doing "emerge -p mozila" and not about emergeing gaim . Just to explain why i used these use var in the example :) , as they clearly refer to mozilla and not gaim!
I was just going to file a bug report for this! I think this would be a great feature. I built Mozilla 1.2.1r2 four times until I figured out I needed to get rid of
I was just going to file a bug report for this! I think this would be a great feature. I built Mozilla 1.2.1r2 four times until I figured out I needed to get rid of gtk2 and add xft to get Mozilla to build with xft. I would have just voted for this bug instead of replying with a me too, but I dont see this option in the Gentoo bugzilla.
And what about ChangeLog output?
Created attachment 6805 [details, diff] use flags in search I've used this for a while -- just a very quick hack... Patched against portage-2.0.46-r4.
Created attachment 6812 [details, diff] colored use flags in search Enhanced emerge's search to display which use vars a package is using -- color-coded: red: not specified in USE purple: specified not to be used (ie -kde) green: specified and used It's not a USE aware emerge but a small step in that direction :)

Just another "me, too" vote... 1.) The official "use.desc" file seems to be quite outdated and incomplete. For example, most of the moz USE flags mentioned below (including "xft"!) are not in "use.desc"! 2.) I've noticed that "use.desc" has been updated several times without updating the "Last updated" comment in it. So this is a clear indication that USE flags should be handled more dynamically!
I'm the one who proposed this improvement. I noticed that the proposed patch (last one) worked without problems. Why was'nt it included yet in the official stable portage branch? Hope that it won't follow the destiny that a lot of others very good patches have followed (see the paralled download patch and some others) : be forgotten. Thanks a lot to all the developers that contributed with patches for the hard work! :) Hope it will be included in portage soon! Waiting for some reply. Stefano Peluchetti
Please not that I am portage maintainer and that I also wrote the parallel merging/fetching code. If it doesn't make it in, then it isn't reasonable, useful, or proper patch. Parallel code conflicts with globals and thus can't be merged. It'll be added when it fits. emerge -evp world -vp == Show use flags
Thanks. I didn't notice that it was already included in the official release. So should'nt this bug be marked as closed? Anyway i hope you did't take my comment like just as a mere crtitic. I just tried to make a constructive citic as "the feeling" , also noticed in the forums, was that sometimes the proposed patch was just abbandoned. Bye Stefano Peluchetti
