Maybe you're talking about #84884: https://bugs.gentoo.org/show_bug.cgi?id=84884 I still do quick and dirty syncs of the emerge patch for my own use. It adds 4 options (when in --pretend or --ask mode): * --use-desc-special prints descriptions of global flags overloaded in use.local.desc. I don't use this one since there is currently no such specific description, but it still works. * --use-desc-new prints descriptions of the new ones (yellow flag% on packages updates). I use this one when i update world. * --use-desc-local prints descriptions of local flags. I use this one when i'm about to install some new package. * --use-desc-all prints descriptions of all USE flags. I don't think it's much useful, but who knows... Sure, if some Portage dev want to have a look at it, i can clean it up and resubmit it once again. i keep meaning to look at how other USE-type utils handle it. At least equery uses pkg/foo needs to be patched too (or it choose the global description when it finds one). Bug #84884 had a patch for that too, which is easy to sync. -- TGL. -- gentoo-dev@gentoo.org mailing list

In connection with latest globalization of mplayer USE flag I would like to ask for globalizing cairo, openexr and udev USE flags. These flags are used by enough amount of packages. cairo - 11 packages openexr - 10 packages udev - 7 packages Each of these USE flags is used by bigger amount of packages than mplayer USE flag. I hope that my proposal will be positively considered.

I don't think any specification precludes having a more descriptive per-package meaning. It would just be a matter of: a. having devs write them in use.local.desc when necessary b. Having tools look in use.local.desc first. But the whole point of global flags is really to consolidate the description functions and keep naming consistent. So I doubt (a) will ever come to pass for the majority of flags. Luckily (a) isn't a hard requirement, tools don't loose functionality by looking in use.local.desc first. -- gentoo-dev@gentoo.org mailing list
Re: [gentoo-dev] Re: Global USE flags (Was: mplayer global use flag)
And that's the problem - the user doesn't know what benefit will it bring her to use or not use a global USE flag for this particular package. yeah and it would be really nice to know these. I just thought of another useful feature. a flag for emerge that assumes --verbose but defines what the use flag's do. maybe we could have one similar to lspci? where -vv is more verbose that just -v. thx Mart for giving a better example than me. because I couldn't come up with a good one at the time. -- gentoo-dev@gentoo.org mailing list

maillog: 29/10/2006-05:26:52(+0200): Mart Raudsepp types The main problem in my eyes here is that with certain USE flags, the description doesn't really convey what the user will get. Many are in the form of adds support for this optional thing instead of by using this optional dependency [named often the same as the USE flag name] you will get this and that extra functionality. Now what good wxGTK maintainer would I be, if I didn't pick wxwindows USE flag as an example: wxwindows - Adds support for wxWindows/wxGTK GUI toolkit Lets see what the user really gets with this in the example of a few packages that use this USE flag in IUSE: app-backup/bacula: a wxWidgets console, while there are other consoles available, such as gnome2-console and having both USE flags will result in two consoles. However all of these are dependent on bacule-console local USE flag... app-emulation-bochs: Compile a wxWidgets based GUI (other are available) media-gfx/zphoto: Use wxWidgets for GUI (to get ANY kind of GUI) media-video/gpac: Build wxOsmo4 and V4Studio media-video/mkvtoolnix: Build mmg and a GUI for mkvinfo All of these support wxGTK in the sense that they pull it in and build a few things against it, but it doesn't articulate what does the user exactly get from using that global USE flag for this particular package. Sometimes she gets just some little extra GUI apps, sometimes a GUI in the first place, sometimes an extra GUI interface in addition to others, and so on. Similar things can be observed with many other global USE flags (and also some local flags) - examples on request (time consuming detail gathering). And that's the problem - the user doesn't know what benefit will it bring her to use or not use a global USE flag for this particular package. That's why the descriptions in the linux kernel are great. They mention exactly what you get and also give advice about the value: If you don't know what Access Control Lists are, say N If unsure, say N If unsure, say N.
