Interesting USE flags link + what it is for.

http://gentoo-portage.com/USE

I am sure someone has posted this but it seems to be updated or somehting and explains the USE flags and what it does + list portage files / new ones.

Very neat website to use as referance.

Have this in installing + upgrading forum part as well but it should likely be here.

Another page I use that has similar information, but laid out in a different way is:

http://www.gentoo.org/dyn/use-index.xml

I like the way the page you reference has links out to more detail, but I've found this page really useful for figuring out which packages use a given USE flag.

Code: Select all

euse -i $flag

...

as an example:

Code: Select all

necoro@Devoty ~ % euse -i gtk
global use flags (searching: gtk)
************************************************************
[+ CD ] gtk - Adds support for x11-libs/gtk+ (The GIMP Toolkit)

local use flags (searching: gtk)
************************************************************

Thanks!

I hadn't run across that command yet.

yumy ... i don't know it .... a very nice addition to my gentoo arsenal ...

thanks

but still not as much info as i want ... i use http://gentoo-portage.com every time ... a lot of info here ... my way of work:

1. jump at 'http://gentoo-portage.com', search for a particular package
2. do a 'emerge -av package', keep it hanging around waiting for my yes or no response
3. jump again at gentoo-portage.com package page, jump again to use flags of that package
4. Now is time to begin the 'scratch my heads' part, some smoke here?, who is thinking so hard?
5. After a lot of comparation i see the light, answer no to point 2 command
6. Begin another USE='something' emerge -av package command, answer yes here, pray, sleep, or hang around for a while
7. Then if something is wrong jump again to point 3, if all is ok i forgot all hassle and move on to next package ...

i'm still learning ...

This is were a GUI comes in handy...

[totedati]

maybe in near future can be but not now ... no portage GUI apps can beat the combinaţion between http://gentoo-portage.com and konsole ... and of course, this means that i love command line & command line utilities very much ... but also love to work in a GUI environment like kde or gnome not in a real and pure console session ... i don't like that ...

when a GUI portage interface can handle live info pulled in realtime from a fresh portage repository, like is now in http://gentoo-portage.com web page, and can show to me all USE flags relevant to that package, with info for what can be used, and why ... then will be a real candidate to try to use it ...

Interesting nobody has mentioned ufed or profuse in this thread yet. They are console based "GUI"(ncurses) editors for USE flags with descriptions, and profuse can be used in X as well with GTK iirc. Nice for when you need more info on a flag but don't have a browser handy.

Oh yeah, and eix can also pull in all the use flags possible for any given package, while another tool (I think equery) allows you to look up relevant use flags for specific versions (because they can and do change occasionally).
