A while back, someone posted a command that I think pu=
lled all the info
from 'emerge -eav world' into a nice neat package so that a GCC upgrade
can be done in smaller increments.  Now, however, I can't seem to find
it in the archives, or in my stored list backup.  Can someone throw me a
copy of that post or point me to the right one online?
    

emerge -pe world|grep /|cut -f2 -d"]"|sed "s/^ /=3D/"

That'll give you a list of packages, with the versions, preceded by "=3D"=
=20
for each one, so emerge will give you exactly the same versions.  You can=
=20
redirect it to a file as necessary.

If you want it without versions, so as to emerge the latest, it gets=20
somewhat hairier, because the version strings are somewhat difficult to=20
automatically delete without error.  I usually just take the lazy way=20
out, replacing that sed above with another cut, as so:

emerge -pe world|grep /|cut -f2 -d"]"|cut -f2 -d" "

That still leaves the versions.  Then I open the redirect file in my=20
favorite editor and use search and replace with prompt, playing with the=20
search pattern and repeating until I get what I want.  A regex pattern of=
=20
-[-abcr.0-9]*$, replaced with <nothing> gets most of it, but leaves=
=20
strings such as -alpha and -beta, which are easy enough to remove on=20
either further searches or manually.  Of course, it's possible to include=
=20
those in the regex search pattern as well, and would be possible to then=20
make that a sed command, but it's difficult to get exactly right, then=20
remember, and easy enough to do in a decent editor, so that's what I do.
