Re: [gentoo-dev] Little prog to check compile-options for packages.

Nice script, thanks.

I think that we are numerous to wonder which packages have to be rebuilt
after a USE flag change: For instance, if a user adds "gtk2" to his USE
flags, applications that support it will only use it after their next
update, whereas he may want to recompile this apps right now.

So my point is that your program could be even more useful if it could
show only diffs on flags that appear in the IUSE variable from their
ebuild. This would be a nice answer to the "what should I recompile?"
question.


Here are a few other ideas of possible improvements:

 * a few options: --cflags-only (-c), --useflags-only (-u), etc.

 * integration into "qpkg" (as yet another "Information Selection"
option). I know "qpkg" is still a bash script, but I think there are
plans for a python version, am I wrong?

 * taking ebuilds cflags filters into account. (Because if you go from
"-O2" to "-O3" in make.conf, and then wonder what packages have to be
recompiled for optimisation, those which filter "-O3" to "-O2" should
not be listed.)


Having said that, I won't blame you if you don't want to implement my
suggestions. I'm not a python programmer myself, and I really don't know
how hard it would be. :)
