I don't like the idea of making app-specific settings in a global file. For
my money I think that a command line switch to emerge/ebuild to turn certain
USE variables on or off would be better. The idea that a user ALWAYS or
NEVER wants to use a particular thing seems a bit rigid to me.

Agreed.

You can do this with BASH already.  just set the use variably as you
like it and then emerge.  or

% USE="foo bar baz" emerge foo/bar

I am not up on the syntax, but you can also use += or -= to remove
variables, I think.

That would work, but I'd rather see a non-shell specific like:

emerge --do-not-use=foo --do-not-use=bar --use=baz foo/bar

Makes it easier for a GUI frontend too....

I think this is the best way of doing this. In other words, I seconds
this approach.

[gentoo-dev] USE settings for specific apps

[Tom von Schwerdtner]

Hey all,

    Some people have suggested that they would like to be able to set some
USE variables for specific apps.....examples escape me, but I know it has
been brought up.

    Anyways, I was thinking something along these lines would work:

----
# Global settings
USE = "this that other etc"

# App specific
USE-mozilla = "!this !that foo"
----

Basicaly, the syntax would be "USE-<appname>".  This portion should be
simple enough to impliment, however the variables pose more of a problem
since you dont want to have to repeat all of the normal USE settings for a
specific app and most of the time you just want to specify a USE setting not
to use (hence the !'s).  Special vars might be good here too, like
"defaults" to inherit all the global USE settings...or "no-defaults" to
ignore them all...

.....thats the general idea....comments?

Hey Tom,

I've heard these requests too; however, adding more complexity doesn't
seem, to me, like the thing to do.  Why not the user read the ebuild prior
to emerging, and modify her USE variables to taste?  I thought this was
standard practice, in fact.

The current state encourages ebuild reading prior to merging, understanding
of how Portage works, and maintains existing elegance.  

More practically, would it even be feasable to add such a feature to
Portage at this stage in its lifecycle?

Very Best Regards,
Gontran

gaim is one example - i *hate* having it built with gnome support because it ends up as a pannel applet then. Otherwise i use gnomesupport for everything else :)
