[gentoo-dev] emerge overide options

[david mattatall]

This idea hit me today at school and I wanted to get it to you guys as quickly 
as possible. So without further APU here it is:

emerge vim -o -gtk -x ncurses

This would overide the current settings for gtk x and ncurses in the 
/etc/make.conf file.

emerge vim -O ncurses

What this would do is apply nothing but the ncurses use flag to the compile.

What do you think, if you need me to elaborate I could.

I like it as a simple way to modify USE flags on the fly (i.e. to work
around a small compile issue), but as it is listed here it could likely
get out of hand quickly, and what happens when you have a use variable
called p, using -p might be confusing even if it is listed after the
ebuild name. Maybe something like a --use-mask="-x +ncurses" would work
and could be masked over the standard USE flags for that build only. The
next questions is does this count for all the dependencies that might
get built as well with that emerge command? Probably should, but could
get people in a bit of trouble if they aren't careful......Of course, so
could a lot of other things.....

This appears to work:

USE="-gtk -x ncurses" emerge vim
or
USE="-* ncurses" emerge vim

The later will ignore everything set by /etc/make.conf
but only include ncurses.

What is wrong with this method?
